Patent ID: 8477841

Claim:
A video processing method comprising: (a) configuring an encoding device to decrease a resolution of a received at least one source image frame on the basis of a received reference signal to thereby obtain reduced image frame content with a reduced resolution, and to generate a relay image frame containing the reduced image frame content; (b) configuring the encoding device to generate a header including at least one element, pack the relay image frame and the header into a video signal, and transmit the video signal to a decoding device, said at least one element containing information of the reduced image frame content in the relay image frame; and (c) configuring the decoding device to obtain a restored image frame from the reduced image frame content in the relay image frame on the basis of said at least one element in the header; wherein, in step (a), the resolution of the source image frame is decreased such that a size of the image frame content is scaled down from the source image frame by a predetermined factor, and in step (b), said at least one element includes the predetermined factor, and wherein the predetermined factor is (1/k) n where (n) and (k) are positive integers.
