====Video decoding processes that can be accelerated==== Video decoding processes that can be accelerated by modern GPU hardware are: * [[Motion compensation|Motion compensation (mocomp)]] * [[Inverse discrete cosine transform|Inverse discrete cosine transform (iDCT)]] ** [[Inverse telecine]] 3:2 and 2:2 pull-down correction * Inverse [[modified discrete cosine transform]] (iMDCT) * In-loop [[deblocking filter (video)|deblocking filter]] * Intra-frame prediction * Inverse [[Quantization (image processing)|quantization]] (IQ) * [[Huffman coding|Variable-length decoding (VLD)]], more commonly known as slice-level acceleration * Spatial-temporal [[deinterlacing]] and automatic [[Interlaced video|interlace]]/[[progressive scan|progressive]] source detection * Bitstream processing ([[Context-adaptive variable-length coding]]/[[Context-adaptive binary arithmetic coding]]) and perfect pixel positioning These operations also have applications in video editing, encoding, and transcoding.
