AV1 introduction

AOMedia Video 1 (AV1) is the latest standard for video compression to replace H265 (HEVC) & VP9 at the moment. This new generation compression standard will bring high-quality video experiences to more people by reducing internet bandwidth as well as reducing the cost of copyright for chip decoding equipment. It helps chip manufacturers integrate decoders into their devices and users increasingly have access to and experience high-quality videos without facing many problems with internet transmission factors and terminal.

AV1 was the Alliance for Open Media's first project specializing in online video technology. The main co-developer of a large company involved in the development of AV1 is Mozilla and AV1 has gradually been used as the main reagent Youtube to date (2009). Since September 2018, Youtube has begun testing AV1 on most new video content & deploying the decoder integrated in its Chrome browser-users must manually turn on in chrome: / config. With this move, AV1 is highly potential for the future when Youtube - Google approves it.

What is the difference between AV1 & AVC / H264

As you may already know, thanks to AVC / H264 (2003) technology, the revolution in the video industry has become popular since the last decade and we often use it today to watch videos or people. It also uses "MP4" familiar. The mp4 has become popular thanks to the compression standard AVC / H264, which has been very popular and popular on all terminals from PC / laptop, TV, setup box, mobile devices, many of which are supported. Decode this standard of compression. MP4 has done a great job of providing users with a video experience to watch video content from low quality to high quality video, which is also known as HD / Full HD without sensor

AV1 and AVC / H264 in comparison

  • The compression standard of the new generation is twice as effective as the old standard - better quality, but takes only half the capacity of the standard AVC / H264
  • Easier to deliver high-quality videos and access to high-quality videos
  • The terminal equipment companies no longer have to pay decoding fees
  • Saving bandwidth and content storage costs for content providers.

By embedding this technology into processors and graphics cards, people can enable broader AV1 in decoding video files, followed by a range of various devices. It is foreseen that AV1 could make appearance in video applications in 2019.
