Abstract:
A decoder receives a bitstream containing quantized coefficients representative of blocks of video representative of a plurality of pixels and decodes the bitstream using context adaptive binary arithmetic coding. The context adaptive binary arithmetic coding decodes the current syntax element using a first mode if the current syntax element is intra-coded and if selecting between a first set of probable modes and a second set of probable modes, where the first set of probable modes are more likely than the second set of probable modes. The context adaptive binary arithmetic coding decodes the current syntax element using a second mode if the current syntax element is intra-coded and if selecting among one of the second set of probable modes.

Claim (Index 1):
A decoder for decoding a prediction mode of a current block, wherein the decoder comprises a regular decoding engine and a bypass decoding engine, the regular decoding engine is used for arithmetic decoding using a context, the bypass decoding engine is used for arithmetic decoding with a bypass decoding process, and wherein the decoder is configured to:\n decode a first indicator using the regular decoding engine; decode a second indicator using the bypass decoding engine to derive the prediction mode of the current block, when a value of the first indicator is equal to a first value, wherein the second indicator is used to indicate the prediction mode of the current block in a most probable mode list, wherein the most probable mode list comprises one or more candidate prediction modes generated according to prediction modes of one or more adjacent blocks of the current block, and wherein the one or more candidate prediction modes of the most probable mode list belong to multiple prediction modes; and decode a third indicator using the bypass decoding engine to derive the prediction mode of the current block, when the value of the first indicator is equal to a second value, wherein the third indicator is used to indicate the prediction mode of the current block in the multiple prediction modes, except for the one or more candidate prediction modes of the most probable mode list, and wherein the second value is different from the first value.
