This is because of bandwidth restrictions or the file size of the videos being streamed.
This may lead to a delay in buffering or a pixelated stream.
We have a ton of them already.
A seven-minute 1080p video would roughly burn 200-600MB of your data, based on the codec used.
In this piece, well talk about an upcoming standard called H.266 or VVC (Versatile Video Codec).
But before we dive into its story, lets start with some basics.
Why do we need video compression?
40% off TNW Conference!
What are the commonly used video compression standards?
Most of these use a mathematical concept called Discrete Cosine Transform (DCT).
Who develops these standards?
Its members consist of Apple, IBM, Huawei, and Nokia.
First, a working group lists out requirements for the standard that is to be developed.
After that, theres a call for proposals where different developers submit their own solutions.
Finally, the standard is based on combining the best parts of different proposals.
What is H.266?
Phew, thats a lot of acronyms.
The JVET will be also responsible for maintaining the existing H.264 and H.265 standards.
Plus, we need to store these videos on our devices.
So if we can compress their size by 50%, it would be great.
you could read the technical details of the H.266 compressions standardhere.
Whats the advantage of H.266?
In comparison, H.266 uses only 5GB of data to stream the same file.
The JVET decided to build H.266 (VVC) for applications beyond video streaming.
The standard has support for beaming 4K to 8K videos seamlessly, along with support for 360-degree videos.
This could be useful in VR and AR applications.
Who is using this and what are the problems?
Other streaming players will also face this challenge and have to follow suit for a while.
While both the encoder and decoder are open-sourced, its hard to develop them both for all companies.
There are also companies likeMPEG-LAandAccess Advancethat offer licenses to H.266.

Qualcomm said last year that we will seecompanies deploying H.266 on a commercial level in 2021.
MX Player and Tencent Cloud are some examples of that, with more to come.
That’s one heck of a mixed bag.
