Abstract:
A video signal processor comprising a first input for receiving a compressed first video signal including parameters associated with the frames of the signal and relating to the compression,a decoder for decoding the compressed first video signal to derive first video information whilst preserving the compression parameters in association with the frames, a second input for receiving additional video information to be combined with the said first video information, a combiner for combing the additional video information with the first video information to produce frames of combined information, and an encoder for encoding the frames of combined video information, reusing the said preserved parameters of each frame for encoding a part of a frame of the combined information which does not contain additional video information and for encoding an edge region of another part of the frame, which another part contains additional information, to a higher picture quality than a region of said another part which is not the edge region.
