Historically, video was stored as an analog signal on magnetic tape. There are complex relationships between the video quality, the amount of data used to represent the video (determined by the bit rate), the complexity of the encoding and decoding algorithms, sensitivity to data losses and errors, ease of editing, random access, and end-to-end delay ( latency).įurther information: Video coding format § History A consequence of this is that decompressed video has lower quality than the original, uncompressed video because there is insufficient information to accurately reconstruct the original video. The compression is typically lossy, meaning that the compressed video lacks some information present in the original video.
The compressed data format usually conforms to a standard video coding format. In the context of video compression, codec is a portmanteau of encoder and decoder, while a device that only compresses is typically called an encoder, and one that only decompresses is a decoder.

Netflix will consider a title's popularity into consideration and start with well-known shows like La Casa de Papel (Money Heist) to make sure the AV1 streaming reaches the most number of viewers. That could lead to longer streaming sessions in 4K resolution.Ī team within the company created a rollout strategy to minimize associated costs with encoding its whole catalogue. In addition, since AV1 has higher compression efficiency than the codecs Netflix is currently using, it needs lesser bandwidth. It also noticed fewer noticeable drops in quality due to changing network conditions and lesser time to start streams.
Netflix conducted comparison testing before rollout and found that AV1 delivers videos with better quality than other codecs, especially when there's network congestion. It was only over the past year that the industry released models capable of AV1 streaming. The company explained that deployment on TVs took sometime because playback on TV platforms depend on hardware.

Now, the streaming giant has enabled AV1 streaming on the PS4 Pro and a limited number of smart TV models. Early last year, Netflix started using a new codec called AV1 on a select set of titles on Android.
