What Is ARC Audio Return Channel?

Audio Return Channel is a feature that is available on TVs, radios, and home theater systems starting with HDMI version 1.4, commonly known as High Speed HDMI. In theory, it’s a pretty basic function that allows you to transport audio from your TV (think of the built-in tuner) to your home theater set or receiver through an HDMI cable so that you can hear it via your speakers. All of this is accomplished using the same HDMI wire that transmits audio and video from the home theater system or receiver to the television. As a result, Audio Return Channel works both ways.

The Audio Return Channel (ARC) uses a single High Speed HDMI cable to link your TV and audio system, eliminating the need for a separate composite audio or optical line.

In brief, you just need one HDMI cable to display images from your receiver or home theater system (such as Blu-ray / DVD movies) to your TV and to listen to audio from your TV. Of course, you don’t use both at the same time; one time, the picture of a film is sent to the television, and the other time, the audio from a television programme is sent to your home theater system. Previously, you had to run a separate audio wire from the TV to your audio system in order to hear TV broadcasts (through the built-in tuner) through your speakers; today, one HDMI cable suffices.

When connecting an Audio/Video (A/V) receiver or surround sound system to a TV, the ARC function removes the need for an extra composite audio wire or an optical cable. 

ARC, or Audio Return Channel, is one of the greatest and least-understood HDMI features. It’s a function that allows you to streamline your system and is compatible with the majority of televisions, receivers, and soundbars.

ARC uses an HDMI connection to transport audio from a TV back to a receiver or soundbar in its most basic form. That means you may utilize a single connection for both audio and video, such as via your TV’s Netflix app or a connected gaming console, and then switch between them using your TV.

What Is An Audio Return Channel?

You know how quickly home theatre difficulties can become complicated if you put more than one or two devices into a TV. While HDMI cables make connections easier, they can pose nearly as many issues as they solve.

Because audio and video are carried over the same wire, audio is a particularly difficult challenge with HDMI. HDMI Audio Return Channel (aka HDMI ARC) is a feature that simplifies your home theatre setup. Let’s look at how it works and what you can get from it.

What Is HDMI ARC and How Does It Work?

HDMI is supposed to make connecting audio and video devices easier. For even the most basic connections, we used to need anywhere from two to five connection ports and many wires. In many cases, HDMI reduces this to a single cable.

Let’s pretend you’re utilizing a soundbar. This is where things become a little more complicated, especially if you want to control the level of the soundbar using your Roku remote. Two alternative HDMI technologies, ARC and Consumer Electronics Control (CEC) were created to address this issue.

CEC allows your remote to send signals to other devices over your HDMI connections. This means you could use a single remote control to control all of the devices connected to your TOnon. ARC ensures that all of your audio ends up in the same spot regardless of source. This may seem straightforward, but it isn’t.

HDMI Audio Return Channel

If you wanted all of your audio to play through a soundbar or A/V receiver before ARC, you had to route all of your devices through the soundbar or receiver, then to the TV. This means that your TV and your receiver must support 4K, HDR, and any other new technology.

The audio return channel handles all audio, both to and from a given device, using a single port. This means that you may connect a soundbar to one of your TV’s HDMI inputs, and audio from other devices will automatically play through that soundbar without any additional preparation.

That’s how it’s meant to operate, at least. HDMI ARC, like most other home entertainment solutions, has flaws. For example, because of the delay in the connection, you may experience situations where the audio and video do not precisely sync.

What is an HDMI Audio Return Channel?

The Audio Return Channel (ARC) removes the need for an extra composite audio or optical cable by connecting your TV and audio system with a single High Speed HDMI cable.

Features of the ARC

When an ARC-compatible audio system is connected to an ARC-compatible TV, the following features become available:

  • Audio from the TV should be sent to the audio system.
  • View and listen to movies and other content transmitted to the TV from the audio system.
  • Control capabilities such as using a single remote to control many devices.

The acronym ARC stands for “Audio Return Channel,” and it’s been available on TVs, soundbars, and receivers since the HDMI 1.4 standard was launched. Over a single HDMI connection, this protocol allows two-way communication between devices. The HDMI ARC connector essentially allows you to utilize HDMI as both an input and an audio output.

HDMI is a connector that can send picture and audio from the source to the receiver and is found on practically all new TVs, Blu-ray players, and receivers. There are several HDMI standards and cables, however many HDMI-equipped devices also have an additional feature called HDMI Audio Return Channel (ARC).

We’re hearing this word more and more, but many people aren’t aware that their TV or receiver has it, let alone what it means or how to use it. Not unexpected, given that manufacturers pay little attention to files other than the words “HDMI ARC support.” Nonetheless, it’s an intriguing feature that provides you additional alternatives with a single wire.

There are two methods to use the Audio Return Channel. To begin with, audio from the TV itself may be supplied to the receiver or home theater set through the built-in (digital) TV tuner, or even audio from applications utilized on a Smart TV platform, and this audio can then be sent over your speakers. Second, the cable may transmit audio from HDMI sources connected to the TV. You may stream audio from your TV to your receiver or home theater set, for example, if you have a digital TV decoder connected to your TV through HDMI. The television functions as a hub for audio transmission in this situation. The latter approach isn’t used by all manufacturers, and it’s also not well defined. Unfortunately, it’s typically a case of trying and failing.

What Is Multi-Channel Audio Recording?

The multi-channel recording is the simultaneous recording of more than two independent audio channels on the same computer, all of which must be synchronized. On most Windows consumer computers, this does not operate “out of the box” and requires the use of suitable hardware and drivers, as well as recording software that can work with that hardware/drivers combination.

Requirements

Hardware support: To do multi-channel recording, you’ll need a sound card or an external audio interface with adequate Analog to Digital Converters (ADCs). Most consumer cards only have one stereo pair of ADCs that can be swapped between other inputs like Line-In and “Mic.” To find support for multi-channel recording, you’ll need at least semi-professional gear.

Driver Support

The device’s drivers must allow for simultaneous recording of more than two channels. This is more difficult than it appears because many operating systems’ basic sound interfaces were created long before multi-channel recording was available, and so only allow for two recording channels. Furthermore, consumer-level systems aren’t built to deliver the short latencies and high throughputs required for high-quality multi-channel recordings.

Program Support

The application you’re recording into should be able to handle multiple audio channels. You can record as many channels as the device allows (for example, In the Devices page of Preferences, you can choose the number of channels you want. Currently, there are two limitations:

  1. Channel Selection

You can’t pick and choose which channels are used. The program will use the first ones it discovers. You might need to raise the number of recording channels in options (perhaps to the maximum enabled by the device, even if you’re only recording a portion of them) until you’ve got what you want. This may necessitate the deletion of silent tracks after they have been recorded. However, certain audio interfaces will show a “Multi” device. When you select this as a recording device, it should immediately record all channels.

  1. Allocation tracking channel

It is not possible to record specific channels of the sound device to specific tracks. After recording, multi-channel files can be exported by selecting the appropriate mixdown option in the Preferences (Import/Export tab). The program supports currently supports stereo playback only. Tus, all multi-channel recordings will be transmitted to your sound device as stereo. If the front left and right speakers are used, or the output is duplicated to the surround channels, your device can probably be set.

What Can You Do With a Music Technology Degree?

A degree in music technology or sound engineering and production may lead to a wide range of job options, from working with artists to make sound for theatre and live events to assisting the police solve crimes via the use of audio forensic technology. After finishing your education, you might work in any of these fields.

Music and Recording Industry

Is that something you’d be interested in doing if you’re a music producer? Before a new album can reach listeners, it must go through many stages of sound production, engineering, mixing, and programming. It also needs a label to represent the artist (A&R), publish their work, and sell it to customers. Record labels like Sony Music or recording studios like Abbey Road can hire you as a music producer or engineer with the abilities you’ve learned in your degree programme.

Radio and TV Broadcasting

Every radio show, TV show, and podcast has a staff of music and/or sound specialists that mix, produce, and edit sound in order to provide viewers and listeners with a faultless and carefully crafted broadcast. As a Sound Engineer for a broadcasting corporation like the BBC, you may edit and mix audio for a wide range of programmes.

Management Of The Audio And Music Industries

To become a manager for artists, venues, music stores or studios and record companies, students who specialise in this field are often interested.

How Has Technology Impacted Pop Music?

Throughout human history, music has been a crucial part of our lives, even before civilization took hold of the human race. It’s impossible to find a civilization on the planet that hasn’t danced to a certain melody of music. In the last two centuries, technology has advanced in ways that were previously unimaginable. In both positive and bad ways, they have changed the way music is made, delivered, and accessible. Since the 18th century, there have been several technical improvements in music, but digitalization of music has been the most significant. It has been a major shift in the music industry’s dynamics and economics since music can be read by computers. Let’s take a look at how technology has both helped and hindered the music industry.

Improved Production

From the instruments to the recording process, music creation has never been greater. In the last two centuries, musical instruments have improved and evolved, capturing the attention of anybody with a keen ear for music. For example, the Electric Guitar, which would go on to have enormous cultural impact, was born in the 1920s. There were many innovators and artists that tried to think outside the box in order to produce louder string sounds by employing electricity. Once it hit the big time, millions of people all around the world began to hear it and love it.

Promotion

In the early 2000s, musicians would appear on shows like Top of the Pops, chart shows, and even in magazines and newspapers to promote their newest singles. It has become easier for musicians to get their music into the hands of consumers via viral videos and social media posts. Consider Canadian sensation Justin Bieber, who was signed to a record company almost immediately after being found by talent manager Scooter Braun through Bieber’s YouTube account in 2008. A few years later, Bieber became one of the world’s most popular performers.

Piracy

As a result of how music is discovered and consumed today, there is also a detrimental side effect to the music industry’s overwhelming reliance on technology. Piracy has cost artists and businesses millions of dollars in lost revenue.

The way we listen to music has undergone a radical transformation. Our mobile devices now allow us to access millions of songs through subscriptions to internet streaming platforms rather than downloading them from sites like LimeWire or relying on the enormous demand for MP3 players in the early noughties. Sales of CDs in the United Kingdom fell from 132 million in 2008 to 32 million in 2018, a dramatic reduction.

However, recent years have seen an increase in the speed at which this paradigm shift has progressed. There was a time when Spotify had 30 million paying customers throughout the world, but by 2019 that number had more than tripled to almost 100 million. Apple Music, which launched in 2015 and currently boasts 60 million paying subscribers worldwide, has a similar story.

Digital Mental Health Interventions

What are digital mental health interventions? Digital technology is employed in innovative therapy treatments for mental health problems. The technologies and techniques vary in design and target different aspects or signs to diagnose mental health issues and work towards therapy or ‘treatment’. Three main functions such interventions serve are; learning, application, and review.

We have asked experts in digital mental health interventions to share their experience and knowledge with us.

Implementation of Digital Tools Provide Access to Mental Health Care

“Mental health is probably the last thing you might think about when talking about health care. We tend to overlook mental health because we can not see the physical consequences of a mental disorder. Until it becomes too serious or until it is too late. According to the World Health Organization, 1 in 4 people will suffer from a mental disorder at least once in their life. If you think about the world population which is around 7 billion people, then you have a gigantic number of people suffering from their mental health. The digital world is not only about Social Media and fancy-looking gadgets, it also produces and offers humanity new tools to make their lives easier and better. Digital Mental Health interventions are digital programs designed to address, treat and help with mental health struggles, especially on people who lack health care providers/resources. Sadly, the accessibility and availability of proper mental health care is a luxury in most parts of our world. The implementation of digital tools that can provide an access to mental health diagnosis and treatments suggest a great hope for humanity, especially in these recent times where in-person appointments are not considered essential, or people don’t have the access to afford a mental health specialist.”

Tom Winter, HR Tech recruitment Advisor & Co-founder of DevSkiller

Mindfulness Tools

“Running a business is not like a walk in the park. It’s hard and you can go insane if you don’t manage yourself effectively. One of my favorite hacks for mindfulness is “Headspace”. It is a mental health app that helps me in meditation and also keeps my stress levels in check. With Headspace I can juggle being a dad as well as a CEO without going crazy.”

Sandra Saenz, Marketing Manager The Spanish Group LLC

Dedicated Line and Live Calling For Patient Care

“OnPage Corporation, a Boston-based clinical communication and collaboration (CC&C) company, recognizes the importance of behavioral therapy and a patient’s need for immediate access to care. The company is dedicated to streamlining care team communication processes in the industry through cutting-edge technology. Aside from relying on OnPage’s CC&C system for care team collaboration, mental health organizations also trust OnPage’s dedicated lines with live call routing capabilities as the first line of intervention. Dedicated lines allow patients to dial one number to reach a clinician’s office. If the patient’s call is answered, the patient connects with the mental health representative on a live phone call. In the event that the first on-call health representative is unavailable, the call automatically routes to the next on-call representative. In the event that no one picks up the call, the patient gets a prompt to leave a voicemail with their contact details. This voicemail then routes through the escalation path until someone responds to it. OnPage’s alert-until-read technology ensures that critical messages are never missed. The feature is designed to rapidly improve patient-to-clinician communications and patient access to immediate care. It ensures that patients receive timely care in times of crisis. Our dedicated lines and live call capabilities are trusted by large mental health organizations including Distress  Center of Ottawa and Region and The Dragonfly House Children’s Advocacy Center. These organizations have shared positive experiences with the OnPage platform. Among both clinicians and crisis line volunteers, their experiences with OnPage resulted in: Improved organizational communications and accelerated patient care, Improved accessibility to immediate care, Seamless workflows.

Judit Sharon, CEO OnPage

Eye-Tracking Software to Diagnose Anxiety

“MindReset: Utilising the very latest in eye tracking software we have partnered with an organisation who created the worlds first eye tracking for mobile phones. The technology traces the users eye movements as they are asked certain context specific questions, for example anxiety. The science behind EMDR tells us that the eye movement correlates to emotional problems, so we are literally able to track the users subconsciously stored memories that are related to the subject matter. Next we use the most up to date research on memory reconsolidation, basically when we access an old memory it comes to life neurochemically for a few hours, by changing the thoughts during this time period, we have a window of opportunity that can allow healing to take place. The app then scans at the end to ensure that the client has had a shift. The funky part of the MindReset app is that it allows the user to access it without giving away any personal data, whatsoever! This is a vital step because research shows that autonomy, the ability to choose freely for oneself, is paramount to helping people to take control of their lives. The mental health crisis is now worse than ever, so we need an effective way to help people improve their mental health on their own terms. The sessions take just 2 minutes, but how can it be so fast? This is where the Split-second Unlearning (SSU) model (under peer review) comes in to play. Trauma and or adverse childhood experiences (ACE’s) can leave life long memories that impact mental and physical health. The memory of the original event is stored as an emotional memory image (EMI) inside the minds eye. This EMI is accessed subconsciously whenever anything resembling the original experience occurs. The SSU model seeks to interrupt the connection between the EMI and the fight/flight/freeze response. This process of ‘unlearning’ must take place rapidly, at the same speed the original trauma took place. The MindReset app technology merges all that we currently know about trauma, mental health and the brain, to give a fast, effective and affordable solution to the the mental health pandemic.”

Matt Hudson, behavior expert, Mind International Training Associates LTD

Digital Mental Health Intervention Tools can greatly aid in mental health diagnosis and treatment, as studies have shown. It is high time mental health was granted the care and attention as physical well-being.

The Discovery of X-Ray

Imagine practicing medicine without seeing inside the body, performing surgery without knowing beforehand which bone is broken. We’re trying to diagnose a condition based solely on the patient’s outward symptoms. The ability to see inside a living human body without cutting it open was a turning point in medical history.

In the late 1800s, Dr. Wilhelm Conrad Röntgen, a German scientist and mathematician, studied at the Polytechnic Institute in Zurich. He was appointed to the University of Furstenberg faculty and was the Physical Institute director at his discovery time. As a teacher and researcher, his academic interest was the conduction of high voltage electricity through low vacuum tubes. A low vacuum tube is simply a glass tube with some of the air evacuated from it. The specific type of tube that Röntgen was working with was called a crooks tube. Upon ending his workday on November 8, 1895, Röntgen prepared his research apparatus for the next experimental session to be conducted and when he would return to his workplace. He darkened his laboratory to observe the electrical glow, the cathode rays that occurred when the two were energized. The tube’s glow would indicate that the two were receiving electricity and were ready for the next experiment. 

On this day, Röntgen covered his two with black cardboard and again electrified the tube. By chance, he noticed a faint glow coming from some material located several feet away from his electrified to the source was a piece of paper coated with barium Platinum cyanide. He did not believe that the cathode rays could reach that far from the tube rock and repeated the experiment. Each time Röntgen energized his tube, he observed this glow coming from the barium Platner cyanide-coated paper. He understood that energy emanating from his tube was causing this paper to produce light or to fluoresce. Fluorescence refers to the instantaneous production of light resulting from some energy interaction, x rays, and some element or compound. In this case, barium plant no cyanide. 

Here is a demonstration of the principle of fluorescence. When a particular material is exposed to radiation, it gives off light. When the radiation stops, so does the glowing light. This is how Röntgen first noticed there was a different type of radiation being produced from the crooks tube. Röntgen was understandably excited about this apparent discovery. But he was also cautious not to make any early assumptions about what he had observed. Before sharing information about his discovery with colleagues, Röntgen spent some time meticulously investigating this new type of energy’s properties. Knowing that others were doing similar research, Röntgen worked earnestly to determine just what broke this energy. He spent the next several weeks working feverishly in his laboratory to investigate as many properties of this energy as he could. He noticed that when he placed his hand between the energized tube and the barium Platinum cyanide coated paper, he could see the bones of his hand glowing on the paper with this fluoroscopic image moving as he moved his hand. Curious about this, he called us, called to his wife Bertha, and said, let me show you what I’m doing because no one will believe this. Then he placed his wife’s hand under the tube and produced a static image of her head using a 15-minute exposure. Upon seeing the image of the bones in her hand, she said, “I have seen my death”. In those days, people only saw skeletons after someone had died. The idea of seeing part of the body on an image of a living person was beyond anyone’s imagination. This became the world’s first radiograph in December 1895. 

After much study, Röntgen decided that his investigations of this energy were completed to inform his physicist colleagues of what they now believed to discover a new form of energy. He called this energy x rays with x, representing the mathematical symbol. On December 28, 1895, Röntgen submitted a scholarly paper on his local professional society’s research activities. Vers Burg Physio Medical Society, written in his native German. His article was titled upon a new kind of race, and it caused a buzz of excitement in the medical and scientific communities. Within a short time, an English translation of this article appeared in the journal Nature, dated January 23, 1896. Rankin views his discovery as an important one, but he also viewed it as primarily academic interest. His interest was in the X-ray itself as a form of energy, not possible practical uses.

Others quickly began assembling their X-ray-producing devices and exposed inanimate objects and tissue, both human and animal, both living and dead, to determine the range of the use of these x rays. Their efforts were primarily driven by skepticism, not belief that x rays could do what had been claimed. Skepticism eventually gave way to productive curiosity, as investigations concentrated on imaging the living human body for medical benefit. 

Rankin’s discovery was lauded as a great significance to science and medicine for his efforts and discoveries. In 1901, Röntgen received the first Nobel Prize presented for physics. The branch of medicine that was concerned with using x rays was called Röntgenology, a unit of radiation exposure was called the Röntgen, and x rays were in the early days, often referred to as Röntgen rays. Within a few weeks, the world had changed. 

The Legacy left by Röntgen can be found throughout medicine, in plain film, x rays, and complex CT scans. And to NASA’s Chandra telescope, astronomers are using to observe and record x rays from across the universe. All from a discovery which happened by accident.

NASA is going to unveil an ‘exciting new discovery’ about the moon

The discovery will ‘inform’ the agency’s Artemis program work, Fox News has learned

By Chris Ciaccia | Fox News October 23, 2020


Ahead of NASA’s return to the moon in 2024, the space agency is teasing an “exciting new discovery” about the celestial satellite.

According to a source familiar with the situation, the discovery, to be announced Monday at noon EST, is expected to “inform” the agency’s Artemis program work.

“This new discovery contributes to NASA’s efforts to learn about the Moon in support of deep space exploration,” NASA said in a statement.

NASA HAS A PLAN FOR YEARLY ARTEMIS MOON FLIGHTS THROUGH 2030. THE FIRST ONE COULD FLY IN 2021.

The announcement will be made from NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA), described as “the world’s largest airborne observatory.”

SOFIA is a modified Boeing 747 airplane capable of flying high in Earth’s atmosphere, allowing for its 9-foot telescope to get a “clear view of the universe and objects in our solar system.” It is able to observe infrared wavelengths that are capable of detecting “phenomena impossible to see with visible light,” NASA added.

NASA’s Artemis program aims to land American astronauts on the moon by 2024 and establish a sustainable human presence.

In 2019, NASA revealed details of its vision for the Artemis Moon Lander that will return American astronauts to the lunar surface. Artemis will also make history by landing the first woman on the moon.

Initial mission capability for 2024 involves landing two astronauts on the moon’s South Pole. Astronauts will live and work out of the lander for six and a half days, according to NASA.

After Apollo 11 astronauts Neil Armstrong and Buzz Aldrin set foot on the moon on July 20, 1969, only 10 more men, all Americans, have walked on the lunar surface. The last NASA astronaut to set foot on the moon was Apollo 17 Mission Commander Gene Cernan, on Dec. 14, 1972.

Why 5G Is the First Stage of a Tech War Between the U.S. and China

by Prabir Purkayastha, Citizen Truth
August 12, 2020


The U.S. tech war on China continues, banning Chinese equipment from its network, and asking its Five Eyes partners and NATO allies to follow suit. It is a market and a technology denial regime that seeks to win back manufacturing that the U.S. and European countries have lost to China.

International trade assumed that goods and equipment could be sourced from any part of the world. The first breach in this scheme was the earlier round of U.S. sanctions on Huawei last year, that any company that used 25 percent or more of U.S. content had to play by the U.S. sanction rules. This meant U.S. software, or chips based on U.S. designs, could not be exported to Huawei. The latest round of U.S. sanctions in May this year stretched the reach of U.S. sanctions to cover any goods produced with U.S. equipment, extending its sovereignty well beyond its borders.

In the last three decades of trade globalization, the U.S. has increasingly outsourced manufacturing to other countries, but still retained control over the global economy through its control over global finance—banks, payment systems, insurance, investment funds. With the fresh slew of sanctions, another layer of U.S. control over the global economy has been revealed: its control over technology, both in terms of intellectual property and critical manufacturing equipment in chip making.

The new trade sanction that the U.S. has imposed is in violation of the World Trade Organization’s rules. It invokes national security, the nuclear option in the WTO, on matters that are clearly trade-related. Why the U.S. has gutted the WTO, refusing to agree to any new nominations to the dispute settlement tribunal, has now become clear. China cannot bring the illegal U.S. sanctions to the WTO for a dispute settlement, as the dispute settlement body itself has been made virtually defunct by the United States.

The battle over 5G and Huawei has become the ground on which the U.S.-China tech war is being fought. The 5G market (including installation and network equipment) is expected to reach $48 billion by 2027, but more importantly, it is expected to drive trillions of dollars of economic output over the installed 5G networks. Any company or country that controls the 5G technology will then have an advantage over others in this economic and technological space.

5G networks will boost wireless internet speeds by a factor of 10 to 40. For consumers, slow internet speed is the bottleneck for applications such as video conferencing and multiplayer online gaming, where both upload and download speeds need to be high. This is not the case with video streaming services like Netflix, where only download speeds are important. Currently, high-speed internet is only available in dense urban areas, and only over fiber-optic cable networks. 5G networks will widen the availability of high-speed internet beyond these limits—and enable it to be accessible by mobile devices.

The two other areas that would benefit from 5G are self-driving cars and the internet of things (IoT), in which our gadgets communicate with each other over wireless internet. While self-driving cars are still some distance away, IoT could soon be much more important, e.g., in improving efficiency and maintaining the physical infrastructure of electricity, traffic lights, water and sewage systems in future “smart cities.”

The G in telecom networks refers to generations, and each generation of technology in wireless communications means increasing the amount of information the radio waves carry. The 5G networks are much faster than the equivalent 4G networks, and can support a much higher number of devices in a given area. The price is that, unlike the current 3G and 4G, 5G cannot travel long distances, and needs a number of repeater hops, meaning cells and antennas, to cover the same distance. Still, a 5G network can provide the high speeds that current fiber-optic cable networks provide, without the large cost of physical cabling. It can, therefore, reach less-dense population centers, including rural areas, with high-speed internet at much lower costs.

Who are the other players in the 5G space? Apart from Huawei, other major players are Samsung (South Korea), Nokia (Finland), Ericsson (Sweden) and ZTE (China). While the U.S. has no major player at the network equipment level, it has Qualcomm, which manufactures wireless components and chipsets, and Apple, which is the market leader in smartphones.

The U.S. sanctions had earlier attacked Huawei using its dominant position on software. Google’s Android powers most of China’s mobile phones, as it does most other non-Apple mobile phones. In semiconductor chips, ARM processors have a leading position in the embedded systems and the mobile market, with most companies that require advanced processors switching over from Intel to ARM. ARM, a UK-based company owned by SoftBank of Japan, does not manufacture chips themselves, but provides designs for cores that go into processors. These are licensed to companies like Huawei, Qualcomm, Samsung and Apple, who design their processors based on ARM cores and get them fabricated in silicon foundries. These processors power mobile network equipment, mobile phones or laptops from different manufacturers.

The silicon foundries that fabricate the actual processors using ARM cores from the designs of Huawei, Samsung or Apple are companies like Taiwan Silicon Manufacturing Company (TSMC). TSMC is the largest silicon foundry in the world, with 48 percent of the global market. Samsung also has a high-capacity silicon foundry, with another 20 percent of the global market. It uses its captive facility for its internal needs, but also for other manufacturers. China has the fifth-largest silicon foundry in the world, Semiconductor Manufacturing International Corporation (SMIC), but it is only one-tenth the size of TSMC. TSMC and Samsung have more-advanced 7-nanometer technology, while SMIC currently has less-advanced 14-nanometer technology.

The earlier U.S. attack on Huawei and China banning U.S. software from Huawei systems meant that Huawei had to change over from Google’s Android mobile operating system and various apps that rode on top of the Android system in Google’s app store (the Google Play Store). Huawei had anticipated this attack and created its own operating system, HarmonyOS, and its own app store. It is also using an open-source version of Android, and its app store—App Gallery—as a replacement for the Google Play Store. How its users will cope without the Google Play Store remains to be seen. It would depend on how many of the app developers switch to Huawei, and the quality of apps developed for Huawei users on the Chinese market.

It was initially thought that ARM processors would not be available for Huawei in the future. This raised a question mark over Huawei’s equipment, as it is critically dependent on the ARM-designed processors for its networking equipment, mobile phones and laptops. ARM initially suspended all future sales of its designs of processors to Huawei, as the U.S. had claimed that it has more than 25 percent U.S. content and therefore fell within the U.S. sanctions regime. Subsequently, ARM has come to the conclusion that its U.S. content is less than 25 percent and therefore not subject to the U.S. sanctions.

This is what precipitated the new sanctions that the U.S. imposed in May. Under these sanctions, if any equipment of U.S. origin is used to produce components or systems for Huawei, then those components or systems also come within its sanctions regime. TSMC uses U.S.-origin machines for its manufacture of chips, and has stopped taking new Huawei orders. Samsung has a mix of U.S. and non-U.S. machines for its fabrication lines and could, if it wanted, switch at least some of these fabrication lines to use only non-U.S. machines. This leaves a window for Huawei to beat the U.S. sanctions. Huawei still has some cards to play, one of which is ceding the high-end mobile phone market to Samsung for access to its chip fabrication facilities.

If Huawei has to depend on only domestic sources, it is going to take a hit on its future production. It has a stockpile of possibly 12-18 months of fabricated chips, so this is the time window it has to either find a new supplier, or a switch to a less-dense—10- or 14-nanometer—technology using its domestic supplier, SMIC.

For the 5G market, the 7-nanometer fabrication may not be the only deciding factor. Huawei has a significant lead in radios and antennas that are key components in 5G networks. 5G networks depend on what are called massive multiple-input and multiple-output (MIMO) antennas, where Huawei is streets ahead of others. This, more than processor size, may decide the technical advantage of Huawei’s offerings. Huawei has a significant lead in gallium nitride-based devices, instead of silicon. Nokia and Ericsson are using Intel chips for their base stations, which are no match for ARM processors. And with Huawei’s support, China’s SMIC in Shanghai may be able to switch to a 10-nanometer technology quickly, shortening the gap between its processors and that of others.

Huawei can provide a complete 5G solution—from networks to 5G mobile phones—and install it much faster than others. Huawei’s home market in China is bigger than all other 5G markets in the world, which can power its growth.

It is certainly not game over for Huawei, as many tech analysts are concluding prematurely. They have already pronounced game over twice, once over Google’s Android system denial, later on the ARM processor ban. With this new set of sanctions, while the U.S. has secured a temporary advantage for other Western players, it has also created an incentive for manufacturers outside the U.S. to move away from U.S. equipment. Such bans are always double-edged weapons.

So it is very much game on for Huawei and China in the tech war with the United States. As with any other war, it is not one battle in one arena that will decide who wins. 5G is only one battle theater; there are many others. And in many of those, China holds the cards. The rest of the world are not mere spectators but will also have to decide where their future lies—not as a binary choice between the U.S. and China, but as independent players. It is the larger forces of political economy at the global level that will decide this war.
