Assistance for Processing Pictures in Concatenated Video Streams

A method, comprising:

• providing a video stream in a transport stream, the first video stream comprising a plurality of compressed pictures;
• and
• providing information in the video stream, wherein the information includes plural data fields, the provided information comprising:
• a first data field corresponding to decompressed pictures yet to be output (DPYTBO) by a video decoder at a potential splice point (IPSP) when the video decoder decompresses the video stream, wherein the value of the first data field is a number corresponding to the DPYTBO by the video decoder at the IPSP;
• and
• a plurality of second data fields, wherein each of the plurality of second data fields corresponds to a respective DPYTBO by the video decoder at the IPSP, wherein the number of second data fields in the plurality of second data field equals to the value of the first data field, and wherein the value of each of the second data field indicates how each of the respectively corresponding DPYTBO at the IPSP is to be output by the video decoder.
