Processing and managing pictures at the concatenation of two video streams
First Claim
1. A method, comprising:
- receiving a video stream in a transport stream, the video stream comprising a plurality of compressed pictures; and
receiving information in the video stream, wherein the information includes plural data fields, the received information comprising;
a first data field corresponding to a location in the video stream of a potential splice point in the video stream, wherein a value of the first data field identifies a location in the video stream after the location of the received information in the video stream;
a second data field corresponding to decompressed pictures yet to be output (DPYTBO) by a video decoder at the identified potential splice point (IPSP) when the video decoder decompresses the video stream, wherein the value of the second data field is a number corresponding to the DPYTBO by the video decoder at the IPSP; and
a third data field corresponding to pictures with contiguous output times (WCOT), wherein the value of the third field corresponds to a set of pictures WCOT of the DPYTBO by the video decoder at the IPSP.

Abstract
Systems and methods that receives a video stream in a transport stream, the first video stream comprising a plurality of compressed pictures, and that receives information in the video stream, wherein the information includes plural data fields, the received information comprising: a first data field corresponding to a location in the video stream of a potential splice point in the video stream, wherein the value of the first data field identifies a location in the video stream after the location of the received information in the video stream; a second data field corresponding to decompressed pictures yet to be output (DPYTBO) by a video decoder at the identified potential splice point (IPSP) when the video decoder decompresses the video stream, wherein the value of the second data field is a number corresponding to the DPYTBO by the video decoder at the IPSP; and a third data field corresponding to pictures with contiguous output times (WCOT), wherein the value of the third field corresponds to a set of pictures WCOT of the DPYTBO by the video decoder at the IPSP.

12. A method, comprising:
- receiving a video stream in a transport stream, the video stream comprising a plurality of compressed pictures; and
receiving information in the video stream, wherein the information includes plural data fields, the received 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 a 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. - View Dependent Claims (13, 14, 15, 16, 17)
