Abstract: An electronic device for encoding a picture is described. The electronic device includes a processor and instructions stored in memory that are in electronic communication with the processor. The instructions are executable to encode a gradual temporal layer access (GTLA) picture. The instructions are further executable to send the GTLA picture.

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 method of decoding a video bitstream is disclosed. The method includes: using a set of previously decoded pictures for decoding a subsequent picture; receiving a delta_poc_msb_present_flag indicating whether a delta_poc_msb_cycle_lt is present or not present, wherein the delta_poc_msb_cycle_lt being present indicates that more than one reference picture in the set of previously decoded pictures having same value, wherein the first previously decoded picture has a temporal ID being equal to zero, is not a RASL picture, not a RADL picture, not a sub-layer non-reference picture.
