Line 7: == 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). The coding process varies greatly depending on which encoder is used (e.g.: [[JPEG\|JPEG]], [[H.264/MPEG-4 AVC\|H.264]]), but the most common steps usually include: partitioning into [[Macroblock\|macroblocks]], transform (e.g.: [[Discrete cosine transform\|DCT]], or [[Discrete wavelet transform\|wavelet]]), [[Quantization_(image_processing)\|quantization]] and [[Entropy encoding\|entropy encoding]]. ~~The intra-coding is actually performed at decoder side, upon receiving the so encoded data stream.~~ == See also ==
