Introduction to Digital Video Encoding
Video is 25/30 fps of synchronised images and audio;
To display a single image of TV-quality video requires 720 Kbytes, so without compression this is 100 GBytes for a 90 minute movie -> video must be compressed !!!
There are formats such as .AVI, QuickTime, .ram, .rm (Real Networks), .wma, .wmp, but the ones that matter are the MPEG family;
Before we look at IR on video we should have some understanding of how video is encoded;
