28 Claims

1. A video encoder for encoding a current picture belonging to a temporal level identified by a temporal_id, the video encoder comprising:

at least one processor circuit; and

at least one memory circuit storing program code that is executed by the at least one processor circuit to perform operations comprising to:

determine a Reference Picture Set (RPS) for the current picture indicating reference pictures that are used when decoding the current picture; and

encode the current picture ensuring that the RPS of the current picture includes no picture having a temporal_id greater than or equal to the temporal_id of the current picture when the current picture is a temporal sub-layer access (TSA) picture, wherein the encoding is configured when the current picture is a temporal switching point and is a TSA picture to trigger a parsing circuit performing parsing of bits representing at least a part of the current picture to determine when coded pictures with temporal_id greater than or equal to the temporal_id of the TSA picture that follow the TSA picture in decoding order include no picture in their reference picture set for which temporal_id is greater than or equal to the temporal_id of the TSA picture.
