摘要： There is a coding including-preparing coding units based on source pictures. The coding units are associated with largest coding tree units (LCTUs) which are polygons of source pictures. A tree format is utilized in processing the LCTUs into coding units. The preparing includes calculating an efficiency measure associated with a source picture position in a coordinate system based on fitting the coordinate system and the source picture with respect to each other. The preparing includes determining the source picture position based on a coding efficiency goal. The preparing includes determining padding areas. The source picture and padding areas are divided into LCTUs based on the coordinate system and the determined source picture position. The LCTUs are partitioned into coding units based on the tree format and a homogeneity rule. There is also a decoding including processing video compression data which is generated based on the coding units.

摘要： A system is configured to transcode a first MPEG stream to a second MPEG stream. The system includes a first MPEG decoder capable of decoding the first MPEG stream and a second MPEG encoder capable of producing the second MPEG stream. The second MPEG encoder is configured to maintain a decoded picture type of I, P, or B. The second MPEG encoder is also configured to maintain a decoded picture structure of frame or field, identify a metadata per each macroblock (MB) of an MB pair of the first MPEG stream, and determine whether to re-encode the MB into the second MPEG stream using one of the frame or the field mode based on the identified metadata. The second MPEG encoder is further configured to re-encode the MB pair into the second MPEG stream using one of the frame or the field mode based on the identified metadata.

摘要： A process performs a search on a base reference frame in a video signal to determine a first motion vector for each of the possible partitions of a current macroblock. The first motion vector for a partition provides the most optimal match for the partition in the base reference frame. An optimal partition for the current macroblock, which gives a minimum motion estimation cost among all the possible partitions in the base reference frame, is determined. The process performs the search on the optimal partition over a non-base reference frame in the video signal to determine a second motion vector that provides the most optimal match for the corresponding partition in the non-base reference frame. A simplified search is performed on each partition other than the optimal partition over the non-base reference frame to determine the second motion vector for the corresponding partition.
