== Coding process ==

Data are usually read from videocamera or videocard as YCbCr data format (often wrong marked as YUV that should be used for analog data only). YUV data is partitioned into [[Macroblocks|macroblock]] of 8x8 (...) pixels. Each macroblock is transformed with [[Discrete cosine transform|DTCDCT]] then quantised, [[ZIG-ZAG]], [[RLE]], [[Huffman coding|Huffman]] --> 100101001.
