Claim:
1. An electronic device for decoding a picture, comprising: (a) an obtaining circuit configured to obtain a Temporal Layer Access (TLA) picture, a Gradual Temporal Layer Access (GTLA) picture, which are followed by pictures in a decoding order; and (b) a decoding circuit configured to decode the TLA picture, the GTLA picture and the pictures following the TLA picture or the GTLA picture, wherein no picture that precedes the TLA picture in the decoding order with a temporal identifier greater than or equal to a temporal identifier of the TLA picture is used for inter prediction when decoding pictures that follow the TLA picture in the decoding order, and no picture that precedes the GTLA picture in the decoding order with a temporal identifier greater than or equal to a temporal identifier of the GTLA picture is used for inter prediction when decoding pictures that follow the GTLA picture in the decoding order with a temporal identifier equal to the temporal identifier of the GTLA picture.
