TL;DR: In this paper, an apparatus and method for obtaining scalability of a video object (VO) whose position and size changes with time is presented, where the position of an upper layer picture and that of a lower layer picture in an absolute coordinate system are determined so that corresponding pixels in an enlarged picture and in the upper layer pictures may be arranged at the same positions in the absolute coordinate systems.

TL;DR: In this article, the authors proposed a method to prevent mismatch errors by preprocessing the set of transform coefficients prior to the inverse othogonal transform (15), which prevents mismatch errors in the MPEG-standard compressor for a motion picture signal.

TL;DR: Methods that support UMA and the tools provided by MPEG-7 to achieve this are discussed, including segmentation and summarization of audio video (AV) content, and finally, transcoding of AV content.

TL;DR: In this article, a data structure is associated with each multimedia bitstream and an automatic format conversion process is used to determine whether or not decoding is required before transcoding is performed, which can save processing time and computer resources in those cases where decoding is not required.

TL;DR: In this paper, an encoder considers a frame representing a picture as comprised of areas and decides which of frame-based or field-based orthogonal transformation will be most efficient at reducing spatial redundancy in that area.
