Original video sequence transcoding method, involves creating upper layer coded along format and having resolution same as resolution of layer of original video sequence, and modifying upper layer using data of lower layer

摘要

The method involves creating a lower layer coded along a format i.e. scalable video coding (SVC) format, and having resolution lower than resolution of a layer of an original video sequence, using data i.e. movement vectors, of the layer of the video sequence. An upper layer coded along the format and having resolution same as the resolution of the layer of the video sequence, is created using the data of the layer of the video sequence. The upper layer is modified using data of the lower layer. Independent claims are also included for the following: (1) a device for transcoding an original video sequence coded along a format (2) an information storage medium comprising instructions for implementing an original video sequence transcoding method (3) a computer program product comprising instructions for implementing an original video sequence transcoding method.
