REDUCING AMOUNT OP DATA IN VIDEO ENCODING

摘要

A method for encoding screen outputs of an application to a series of video sequences, in which each video sequence can comprise an intra-frame (I-frame) and inter-frames (P-frames) relating to the I-frame, and each video sequence is formed for one screen output. The method can comprise forming a first video sequence for a first screen output, wherein the first video sequence can include an I-frame and (p-frames), and forming a second video sequence including an I-frame and (P-frames) for a second screen output, wherein the I-frame of the second video sequence can be obtained by encoding a changed area of the second screen output compared to the first screen output. A device for encoding, encoder, a device for decoding, and a decoding are also provided. The video data can be reduced according to the present invention.
