Abstract: Methods, systems, and computer program products that use descriptive information in a coded video stream to accelerate the transcoding process. This information, including information that is sometimes known as syntax information, may reside explicitly in headers of a coded stream. Examples of such information may include motion vectors, macroblock types, intra block prediction modes, inter block descriptive information, and quantization parameters. Other descriptive information may be derived from the actual coded macroblocks, e.g., the number of bits used to encode a macroblock, or the number of non-zero coefficients used in encoding, or the coefficients themselves. Such descriptive information may be used directly in the encoding phase of the transcoding process to improve the speed and throughput of the transcoding. Such descriptive information may also be used to enhance other video processing applications, such as scene change detection, determining object segmentation, or motion censoring.

Abstract: In one embodiment, a method of performing video image decoding includes the following. A compressed video image is downsampled in the frequency domain. The downsampled video image is inverse transformed. Motion compensation for the downsampled image is performed in the spatial domain.
