Che cos'è il formato AV1 e come influenza la tua vita?

Avez-vous entendu parler du format vidéo AV1 ? Ce format est une nouvelle norme de compression qui promet d'améliorer la qualité vidéo tout en réduisant la taille du fichier. Si vous regardez fréquemment des vidéos en streaming, les fichiers AV1 pourraient avoir un impact sur votre vie, et nous commençons tout juste à en voir le potentiel. Examinons de plus près ce qu'est AV1 et ce que vous devez savoir sur ce nouveau codec vidéo.

Partie 1 : D'où vient-il ?

AV1 (AOMedia Video 1) is a new video compression format that is being developed by the Alliance for Open Media (AOMedia). AOMedia is a consortium of major tech companies including Google, Microsoft, Netflix, and Amazon. The AV1 codec is an improvement on VP9 in several ways, most notably in its ability to compress video more efficiently.

Although the AV1 codec is still in the early stages of development, it is already being adopted by some major tech companies. Netflix has announced that it will start using AV1 for its streaming service, and Google has said that AV1 will be the default codec for YouTube.

How can streaming platforms and users benefit from a new codec?

The importance of codecs

A codec is a device that encodes and decodes digital audio signals. Without a codec, your audio would sound garbled and distorted. There are two metrics to take into account to judge the performance of video codecs: quality and bitrate.

The benefits of the new codec

Two of the most popular video formats, provide high-quality video at a relatively low bit rate.

The new AV1 codec offers several benefits for streaming platforms and their users. Take a look at a few of them:

1. Lower bitrate

2. Reduced costs for encoding

For streaming platforms, AV1 could lead to reducing costs for encoding as well as increasing quality and compatibility. For users, AV1 could improve streaming quality, especially on mobile devices.

3. Smaller size with better quality

fichiers AV1 will take up less space on your hard drive or be smaller in file size when streamed online. Since AV1 can compress video files to a much smaller size without sacrificing quality, users will be able to save data when streaming video on their devices!

4. More efficient

AV1 will use less processing power to decode a video compared to other video codecs. As a result, the streaming platforms can save on bandwidth costs, which can be passed on to users in the form of lower subscription prices eventually.

5. Royalty-free

The ultimate goal of AOMedia is to develop an open and royalty-free video codec that can be used by anyone. So, you will have better video quality, lower bandwidth costs, and faster loading times.

AV1 is just one of the many new technologies that are revolutionizing online media delivery. With its superior quality and efficiency, AV1 is poised to become the standard codec for online video in the years to come where everyone can access more affordable and high-quality videos.

Part 2: What are the Trends of Codec War AV1?

As we have already discussed, AV1 is a newer codec that promises better compression. This video format has already been widely used and gaining traction in the streaming industry. It is being used more for live broadcasts and other time-sensitive applications.

Who will prevail?

Since both codecs have their pros and cons, it's unclear which one will ultimately prevail. However, as the world moves towards more open standards for video codecs, there is growing concern that AV1 codec will be used to monopolize the market. While AV1 is free to use, it is encumbered by patents held by members of the Alliance for Open Media (AOMedia), which includes companies like Google, Microsoft, and Apple.

How would AV1 monopolize the market?

The EU Commissions' questionnaire, as reported by Reuters, unveiled that the alliance and its members had been requiring companies to cross-license their patents for no charge to receive the AV1 format. These companies had no affiliation with AOM when AV1 was originally devised. This was a non-negotiable requisite for companies who owned patents that were necessary to contribute to the AV1 standard's technical specifications.

As a result, this action is concerned to hinder innovation and thus prevents the new entities feasible to flourish. Therefore, there is a growing movement to antitrust AV1 which has been investigated by the European Commission.

What happened after the AV1 Antitrust Investigation

The European Commission is looking into whether this licensing scheme violates antitrust law and whether the companies involved are colluding to keep AV1 closed off to competitors. The investigation is in its early stages, and no formal charges have been filed against Google at this time.

However, if the Commission finds that Google has indeed abused its market position, it could order Google to make changes to AV1 or face steep fines. Although the fines have yet to be determined, each company involved could ultimately pay up to 10% of their global turnover.

Nonetheless, this issue has shed light on the competitive landscape of the codec market. Well, although the outcome of the antitrust investigation is still uncertain, it is clear that it has the potential to shake up the codec market.

Codec H.266

H.266 is the next-generation video codec that is being developed to improve upon the current standard and the latest advances in video technology. We can expect H.266 to continue to evolve and be improved upon as time goes on. Some of their transcendence that you can look forward to:

• Améliorer l'efficacité de compression

H.266/VVC is designed to improve compression efficiency by 20-50% over previous versions. You can have a video of the same file size and bit rate but make it look significantly better.

• Utilisation de la prédiction inter-couches (ILP)

Le codec H.266 utilise un nouveau type de prédiction inter-trames appelée prédiction inter-couches (ILP). L'ILP permet au codec d'exploiter les corrélations entre différentes couches d'un signal vidéo. Par conséquent, il donne de meilleurs résultats en termes de qualité d'image et de taille de fichier lorsque vous encodez une vidéo avec le codec H.266.

• Vidéo de meilleure qualité

Nous pouvons nous attendre à ce que le contenu vidéo de meilleure qualité se généralise davantage. Ce nouveau codec permettra également d'offrir de nouveaux types de contenu, tels que la réalité virtuelle et les vidéos à 360 degrés, diffusés et appréciés par un public plus large.

Codec AV2

Le codec AV2 est une amélioration de l'actuel AV1. On dit que le codec AV2 est plus efficace et de meilleure qualité que le codec AV1. Il est encore en développement et n'est pas encore disponible à l'utilisation.

Étant donné que ce codec est censé fournir des vidéos de meilleure qualité à des débits binaires plus bas que d'autres codecs, il serait idéal pour une utilisation dans des applications vidéo telles que le streaming et la visioconférence. Alors, à quoi peut-on s'attendre du codec AV2 à l'avenir ? Voici quelques points à surveiller :

• Amélioration de la qualité à des débits binaires plus bas
• Une adoption plus large dans les applications de streaming et de visioconférence
• Continuité du développement et des améliorations

FAQs: To cater to people also ask

1. Comment ouvrir un fichier AV1 ?

AV1 est un format de fichier relativement nouveau. Si vous avez un fichier AV1 que vous devez ouvrir, vous pouvez utiliser l'une des méthodes suivantes :

• Utilisez un lecteur multimédia qui prend en charge AV1, tel que VLC Media Player ou MPV
• Utilisez un logiciel de conversion pour convertir le fichier AV1 dans un format de fichier plus largement pris en charge

2. Est-ce que MP4 peut contenir AV1 ?

Proprio cosi'. Sebbene AV1 sia un codec relativamente nuovo, è stato supportato da molti lettori multimediali e dispositivi popolari. MP4 è un formato contenitore, il che significa che può contenere più tipi di dati. I dati possono essere codificati con qualsiasi codec, incluso AV1. In questo modo è possibile codificare il contenuto come AV1 e memorizzarlo in un contenitore MP4 per la riproduzione sul dispositivo.
