• H04N 19/1 using adaptive coding
• H04N 19/2 using video object coding
• H04N 19/3 using hierarchical techniques, e.g. scalability
• H04N 19/4 using video transcoding, i.e. partial or full decoding of a coded input stream followed by re-encoding of the decoded output stream
• H04N 19/42 characterised by implementation details or hardware specially adapted for video compression or decompression, e.g. dedicated software implementation
• H04N 19/44 Decoders specially adapted therefor, e.g. video decoders which are asymmetric with respect to the encoder
• H04N 19/46 Embedding additional information in the video signal during the compression process
• H04N 19/48 using compressed domain processing techniques other than decoding, e.g. modification of transform coefficients, variable length coding [VLC] data or run-length data
• H04N 19/5 using predictive coding
• H04N 19/6 using transform coding
• H04N 19/65 using error resilience
• H04N 19/7 characterised by syntax aspects related to video coding, e.g. related to compression standards
