First Claim
1. A computer readable medium for storing a computer program which, when executed by a processor, provides a data structure for representing a plurality of image frame sequences, where each image frame sequence comprises image frames having common image frame portions and respective image frame portions, each of said plurality of image frame sequences having associated with it a respective stream, wherein each stream comprises groups of pictures (GOP) having a first picture and at least one remaining picture, the data structure comprising:
- a first set of at least one element for representing data for the first pictures in the plurality of GOPs, wherein each of at least one element in the first set represents data for at least a portion of the first picture of a respective GOP encoded as an I-picture, and wherein each of remaining elements in the first set represents data for at least a portion of the first picture of a respective remaining GOP encoded as at least one of a B-picture and a P-picture; and
a second set of one or more elements for representing data for the one or more remaining pictures in the plurality of GOPs, wherein each element in the second set represents data for at least a portion of a particular remaining picture in one of the plurality of GOPs encoded as at least one of a B-picture and a P-picture, andwherein each of the plurality of streams is represented by one or more elements in the first set and one or more elements in the second set.

Abstract
A data structure for representing program data that includes a number of streams. Each stream comprises a group of pictures (GOP) having a first picture and remaining pictures. The data structure includes a first set of one or more elements for representing data for the first pictures in the GOPs, and a second set of one or more elements for representing data for the remaining pictures in the GOPs. At least one element in the first set represents data for the first picture of at least one respective GOP, with each such first picture having been encoded as a reference I picture. Each remaining element (if any) in the first set represents data for the first picture of a respective remaining GOP, with each such remaining first picture having been encoded as either a difference picture or a P picture. Each element in the second set represents data for a particular remaining picture in one of the GOPs, with each such remaining picture having been encoded as either a P or B picture. Each stream is represented by one or more elements in the first set and one or more elements in the second set.

12. A computer readable medium for storing a computer program which, when executed by a processor, provides a data structure, comprising:
-
a multiplexed stream comprising a plurality of video streams representing respective first portions of a group of pictures (GOP) information structure, each of said respective first portions including an access unit associated with an I-picture, and a video stream representing a remaining portion of said GOP information structure including at least one of an access unit associated with a P-picture and an access unit associated with a B-picture, wherein; a concatenation of one of said respective first portions of said GOP information structure and said remaining portion of said GOP structure results in a complete GOP information structure. - View Dependent Claims (13, 14, 15)

16. A method, comprising:
-
multiplexing each of a plurality of video streams representing respective first portions of groups of pictures (GOP) information structures, each of said respective first portions including an access unit associated with an I-picture, and a video stream representing a remaining portion of said GOP information structure including at least one of an access unit associated with a P-picture and an access unit associated with a B-picture, wherein; a concatenation of one of said respective first portions of said GOP information structure and said remaining portion of said GOP structure results in a complete GOP information structure.
