    摘要： A multimedia program type of a received multimedia data is determined. Based on the determined multimedia program type, a peak bit rate limit and/or an average bit rate limit are determined. In instances where a transrated version of the multimedia data is to be stored, a remaining storage capacity of a storage device is determined and the peak bit rate limit and/or the average bit rate limit can be adjusted based on the remaining storage capacity. The multimedia data then is transrated to generate transrated multimedia data that has a peak bit rate that does not exceed the selected peak bit rate limit and/or having an average bit rate that does not exceed the selected average bit rate limit. The transrating of the multimedia additionally can include the application of rule sets based on content characteristics. After transrating, the multimedia data can be transmitted via a network to a destination multimedia device, stored locally for subsequent use, or a combination thereof.

    摘要： A motion compensation module can be used in a video encoder for encoding a video input signal that includes a sequence of images that are segmented into a plurality of macroblocks. The motion compensation module includes a shared memory and a motion search module that generates a motion search motion vector for a plurality of subblocks for a plurality of partitionings of a macroblock of a plurality of macroblocks and generates a selected group of the plurality of partitionings and stores the selected group of partitionings and the corresponding motion search motion vectors in the shared memory. A motion refinement module retrieves the selected group of partitionings and the corresponding motion search motion vectors from the shared memory, that generates a refined motion vector for the plurality of subblocks for the selected group of the plurality of partitionings of the macroblock of the plurality of macroblocks, based on the motion search motion vector for each of the plurality of subblocks of the macroblock of the plurality of macroblocks.

    摘要： A transcoder is arranged to transcode a stream having a dynamically changing audio configuration, such as a changing number of audio channels. The transcoder can receive an input stream whereby changes in the content associated with the input stream causes corresponding changes to the configuration of audio data encoded in the input stream. The transcoder is arranged to detect the change in audio configuration and, in response, to dynamically reconfigure its decoder and encoder modules to continue to transcode the audio data after the audio configuration change.

    摘要： A system for processing a video signal includes a static region identification and separation module for generating static region image data corresponding to a static region of the video signal, for generating dynamic region video data corresponding to at least one dynamic region in the video signal and for generating dynamic region location data that indicates at least one location corresponding to the at least one dynamic region in the video signal. A static region encoding module image encodes the state region image data to produce encoded static region data. A video encoder section generates at least one encoded video signal by compressing the dynamic region video data.
