What is a compression stream?

The Compression Streams API provides a JavaScript API for compressing and decompressing streams of data using the gzip or deflate formats. Built in compression means that JavaScript applications will not need to include a compression library, which makes the download size of the application smaller.

What compression do streaming services use?

Streaming requires the use of both audio and video codecs. H. 264, also known as AVC (Advanced Video Coding), is the most common video codec; AAC (Advanced Audio Coding) is the most common audio codec.

Is streaming compressed?

For this reason, streaming of both high-resolution computer graphics and full-motion HD video over networks requires compression. Video compression uses coding techniques to reduce redundancy within successive frames.

What are the two types of compression?

There are two types of compression: lossless and lossy.
