摘要： A method for determining quantization parameters is provided. The method includes determining one or more first units of video content in a grouping of units and analyzing whether the one or more first units of video content within a region in the grouping of units have coefficients for the video content that are zero. The method then determines whether a quantization parameter for one or more second units of video content different from the one or more first units of video content is to be used to derive the quantization parameter for the one or more first units of video content. When the quantization parameter for the one or more second units of video content is to be used, the quantization parameter for the one or more first units of video content is derived from the quantization parameter for the one or more second units of video content.

摘要： The present invention is a system and method for restructuring a group of pictures in such a manner as to provide for random access into the group of pictures without substantially degrading the quality of service for the video content. When encoding a current picture, if the current picture is an I picture, the current picture is encoded utilizing intra coding. If the current picture is not an I picture, and is not referenced by future pictures, the current picture is compressed using an arbitrary number of pictures in the past as a reference. If the current picture is not an I picture, and the current picture is not referenced by future pictures, the picture is compressed and the number of reference pictures in the past are limited so that picture prior to the last I picture are not used as a reference. This process continues W1til the conclusion of the group of pictures.

摘要： In a method of encoding video content, bits of a first view and a second view of a three-dimensional (3D) video content are manipulated to occupy a first slice of video and a second slice of video, wherein a boundary is configured to be formed between the first and second slices. In addition, the bits of each of the first slice and the second slice are encoded separately from each other to form a first independently compressed video slice and a second independently compressed video slice. The first and second independently compressed video slices are then multiplexed to form at least one transport stream operable to be processed to render at least one of two-dimensional (2D) and 3D video.
