摘要： Systems and methods of the present disclosure provide for dynamic delay equalization of related media signals in a media transport system. Methods include receiving a plurality of related media signals, transporting the related media signals along different media paths, calculating uncorrected propagation delays for the media paths, and delaying each of the related media signals by an amount related to the difference between the longest propagation delay (of the uncorrected propagation delays) and the uncorrected propagation delay of the related media signal/media path. Calculating the uncorrected propagation delays and delaying the related media signals may be performed in response to a change to the propagation delay of at least one of the related media signals/media paths. Additionally or alternatively, calculating the uncorrected propagation delays and delaying the related media signals may be performed while transporting the related media signals.

摘要： Methods and apparatuses for data pruning for video compression using example-based super resolution are provided. A method and apparatus for encoding is provided in which patches of video are extracted from input video, grouped together using a clustering method, and representative patches are packed into patch frames. The original video is downsized and sent either along with, or in addition to, the patch frames. At a decoder, the method and apparatus provided extract patches from the patch frames and create a patch library. The regular video frames are upsized and the low resolution patches are replaced by patches from the patch library by searching the library using the patches in the decoded regular frames as keywords. If there are no appropriate patches, no replacement is made. A post processing procedure is used to enhance the spatiotemporal smoothness of the recovered video.

摘要： A difference vector determination element used in an apparatus for coding motion vector includes register memories (PMV) of which number is equal to sum of maximum transmission numbers N and M of forward predictive and backward predictive motion vectors. Motion vector counter counts the number of transmission of motion vectors to output a motion vector count signal. Register index designation signal generator designates indices of (1.about.N (N+1).about.(N+M)) in order of transmission of forward predictive or backward predictive motion vectors on the basis of attached information such as motion compensation mode, prediction type, and picture structure, etc. of motion vector, and the motion vector count signal from the motion vector counter to allow switch to perform switching operation, thus allowing register memories (PMV) and motion vectors to have one-to-one correspondence relationship. Difference circuit determines a difference between a motion vector inputted thereto and a value taken out from register memory (PMV) caused to correspond to the motion vector on the basis of motion compensation mode, etc.

摘要： Image processing method and apparatus for converting between data encoded in different formats includes structure and steps for converting motion image data into first digital coded motion image data having a first encoding format and capable of being transmitted to a medium. The first digital coded motion image data is then converted into second digital coded motion image data without decoding entirely the first digital coded motion image data. The second digital coded motion image data has a second encoding format different from the first encoding format. Preferably, the second digital coded motion image data has a digital data amount which is less than that of the first digital coded motion image data.
