Abstract
Abstract For a television signal having a succession of video frames, at least some of which have an image area and a non-image area, a frame having a non-image area is encoded by generating identification data descriptive of the location within the frame of the non-image area, video encoding only the image area to produce encoded image data, and providing the identification data and the encoded image data as outputs for subsequent decoding of the frame.
