Abstract: A two-pass encoder determines a quantization parameter (QP) value to control an actual number of bits consumed in a second encoding pass. The two-pass encoder includes a first encoding module, a rate control module and a second encoding module. The first encoding module includes a circuit configured to perform a first encoding pass to encode input video sequences. The rate control module is configured to determine R, a target bit rate for a picture in the second encoding pass, and α, a variable dependent on a QP value range, a picture type, and complexity. Q, a QP value for the picture or an MB of the picture in the second encoding pass, is also determined based on R and α. The second encoding module is configured to use Q to encode the picture or the MB of the picture in the input video sequence in the second encoding pass to form an output bitstream. The rate control module is further configured to update α to encode a next picture or a next MB of the picture in the second encoding pass.

Abstract: In one embodiment, a spatial merge mode or a temporal merge mode for a block of video content may be used in merging motion parameters. Both spatial and temporal merge parameters are considered concurrently and do not require utilization of bits or flags or indexing to signal a decoder. If the spatial merge mode is determined, the method merges the block of video content with a spatially-located block, where merging shares motion parameters between the spatially-located block and the block of video content. If the temporal merge mode is determined, the method merges the block of video content with a temporally-located block, where merging shares motion parameters between the temporally-located block and the block of video content.

Abstract: 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.

Abstract: A plurality of programs are statistically multiplexed using a plurality of two-pass encoders. Pictures in the plurality of programs are encoded in a first encoding pass using a plurality of first encoding modules. RW—passOne, which is a total number of bits used to encode all the pictures in a sequence in the plurality of programs in the first encoding pass, is determined. RW—passTwo, which is a total target number of bits for all pictures in a same sequence in the plurality of programs in a second encoding pass, is also determined. Rtwo,Ff,picType(i,l), which is a target bit allocation for each picture in each program l of the plurality of programs, is determined based on RW—passOne, RW—passTwo, and Rone,Ff,picType(i,l). Rone,Ff,picType(i,l) is a number of bits consumed for a corresponding picture in the first encoding pass. The plurality of programs are encoded using a plurality of second encoding modules and Rtwo,Ff,picType(i,l) in the second encoding pass to form a plurality of variable bit rate (VBR) compressed bit streams. Thereafter, the plurality of VBR compressed bit streams are multiplexed to form a single constant bit rate (CBR) bit stream.
