Abstract:
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.).
