An apparatus and method for screen content encoding includes deriving a palette table and a color index map based on a coding unit (CU). The method also includes encoding the palette table and encoding the color index map. The method further includes combining the encoded palette table and the encoded color index map for transmission to a receiver, where the palette table and index map are decoded to reconstruct a pixel block.

Advanced screen content coding with improved color table and index map coding methods

An encoding apparatus, decoding apparatus, and coding methods are provided. A method of decoding including receiving, by a decoder, a bitstream from an encoder, scanning, using the decoder, the bitstream to identify a first flag corresponding to a string of index values in a block other than a last string and a second flag corresponding to the last string of index values from the block, determining, by the decoder, that a context model used to encode the first flag is the same as the context model used to encode the second flag, and generating, by the decoder, a video frame using the context model.

Advanced coding techniques for high efficiency video coding (HEVC) screen content coding (SCC) extensions

An apparatus is configured to perform a method for screen content encoding. The method includes deriving a palette table and a color index map based on a coding unit (CU). The method also includes encoding the palette table and encoding the color index map.

Advanced screen content coding with improved palette table and index map coding methods

An encoding apparatus and coding methods. The method includes receiving a video frame including screen content, generating a block containing an index map of colors for screen content in the video frame, wherein the block includes strings of index values, encoding one or multiple consecutive index values in a first string of index values using same escape colors index values and a run value identifying how many of the same escape color index values have been consecutively encoded, where the escape colors index values represent escape colors, and where the escape colors are colors not included in a palette corresponding to the block, sequentially encoding the escape colors corresponding to the one or multiple consecutive index values after all of the strings of index values of the block have been encoded, and transmitting the strings of index values and the escape colors in a bitstream to a decoding apparatus.

Palette mode in high efficiency video coding (HEVC) screen content coding (SCC)

Apparatus and methods for a Motion Picture Experts Group (MPEG) media transport (MMT) device for sending or receiving media content is provided. The MMT device comprises a memory unit and a controller. The controller is configured to measure an available bandwidth, receive fragments of a first encoded stream of the media content and fragments of a second encoded stream of the same media content based on the available bandwidth and a current transmission bandwidth. A mixed encoded stream comprises the fragments received from the first encoded stream and the fragments received from the second encoded stream.

Method and apparatus for rate adaptation in motion picture experts group media transport

Presented systems and methods facilitate screen content coding. A system can comprises: a processing component configured to execute coding operations and a storage component configured to store information for the processing component, including the color table and color index map. The coding operations can include: receiving information associated with a plurality of pixels; creating a color table, the color table includes color values (e.g., of the pixels) and corresponding indices; creating a color index map wherein each index of the color map maps a pixel to an index value of the color table; and performing coding operations corresponding to the color table and color index map. In one exemplary implementation, index values of the color table are encoded/decoded during color table and index map coding rather than the actual raw color values for each pixel. Various types of compression and coding can be implemented (e.g., lossless, lossy, intra-prediction, inter-prediction, etc.).

Screen content coding systems and methods

An encoding apparatus, decoding apparatus, and coding methods. The encoding apparatus includes a processor configured to receive a video frame including screen content, generate a block containing an index map of colors for screen content in the video frame, wherein the block includes strings of index values sharing a same escape color index value, wherein the escape color index value represents an escape color, encode each of the strings of index values in the block, and sequentially encode the escape colors after each of the strings of index values in the block has been encoded. A transmitter operably coupled to the processor is configured to transmit the strings of index values and the escape colors in a bitstream to a decoding apparatus.
