components (RGB or Y'CbCr) A video consists of a sequence of pictures: 24fps, 50fps, 60fps A FullHD picture contains 1920x1080 (~2 million) samples Uncompressed this could be more than 2000 mbps Video codecs use a combination of temporal and spatial prediction to reduce the amount of transmitted information Often by a factor above 200:1 Encoding Bitstream ...10010110...
