Abstract: A method for decoding a picture on an electronic device is described. The method includes obtaining a bitstream. The method also includes obtaining a current picture. The method further includes obtaining a relative reference picture set (RPS) parameter. The method additionally includes initializing an index value. Furthermore, the method includes processing another RPS parameter based on the index value. The method also includes decoding the current picture.

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 the first mode if the current syntax element is intra-coded and 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 the second mode if the current syntax element is intra-coded and if selecting among one of the second set of probable modes.
