Abstract
A method and apparatus are provided for video signal processing of sequences of digitized images originating from video (10) or film. A field grabber (12) receives the digitized images from the input and identifies the separate fields thereof. An image manipulation stage (14) combines fields as required and reduces the number of pixels per line and pixel lines in each image by applying horizontal and vertical compression; this stage also provides filtering and resizing of the image as required. Following encoding (16) of the compressed images, the encoded data stream may then be processed (18) into a form for recording onto, for example, an optical disc. By appropriate choice of the number of lines to which the image manipulation stage (14) reduces the image, discs playable on either or NTSC standard equipment may be produced from a single image source.
