What is Video Compression and Why it Matters

• Compression is a Must. Video is 80% of the internet traffic*.

• The encoding technology is key

• ITU (Geneva) defines international standards MPEG-2 (1994), MPEG-4 (2003), HEVC (2013).

• An intelligent encoder (eg. including objects tracking algorithms) requires less bitrate for the same video quality (or generates a better video quality at a given bitrate).

• The decoder is passive (2 decoders would always display the same video). No innovation there.

Whatever the network (cable, internet, satellite, terrestrial), digital video has to be compressed 500x typically

Uncompressed HD Video

~ 2 Gbits/s Encoder
