System and method for video coding

An apparatus for generating a stream of encoded video information including a plurality of frames, each having a plurality of blocks, the apparatus comprising:

• a memory;
• and
• a processor configured to execute instructions stored in the memory to:
• for at least a first frame, generate a segment map associating at least one block in the first frame with at least one segment identifier, and associating the at least one segment identifier with at least one segment parameter;
• select a current block of the first frame for encoding;
• generate an encoded segment identifier by encoding a segment identifier associated with the current block based on the segment map;
• generate an encoded current block by encoding the current block using the segment parameter associated with the segment identifier that is associated with the current block;
• include the encoded segment identifier and the encoded current block in an output bitstream;
• and
• transmit or store the output bitstream.

An apparatus for decoding a stream of encoded video information, the apparatus comprising:

• a memory;
• and
• a processor configured to execute instructions stored in the memory to:
• receive an encoded video stream, the encoded video stream including encoded video information, the encoded video information including a plurality of frames, each frame from the plurality of frames including a plurality of blocks;
• for at least a first frame, read from the encoded video information a segment map associating at least some of the plurality of blocks in the first frame with at least one segment identifier;
• read, from the encoded video information, a current encoded block of the first frame;
• read, from the segment map, a segment identifier associated with the current encoded block;
• read, from the encoded video information, segment parameter associated with the segment identifier that is associated with the current encoded block;
• generate a decoded current block by decoding the current encoded block using the segment parameter associated with the segment identifier that is associated with the current encoded block;
• for a second frame, generate a decoded second block by decoding a block from the second frame corresponding to the current encoded block in the first frame using the segment identifier that is associated with the current encoded block;
• and
• output the decoded second block from the second frame for presentation.
