摘要： The invention relates to the compression coding of video signals, and in particular relates to the compression coding of two or more video signals. The invention is particularly suitable for the compression coding of two stereoscopic video signals in a 3 dimensional television system.The invention provides a compression coder and a method of compression coding a primary video signal and at least one secondary video signal. Primary pictures from the primary video signal and secondary pictures from the secondary video signal are combined to form a combined video signal comprising an alternating sequence of pictures from the primary video signal and from the secondary video signal. The combined video signal is then compression coded to form a single compressed bit stream.The invention also provides a compression decoder and method of compression decoding a compressed bit stream comprising a plurality of compressed video pictures, wherein each of the compressed video pictures is a primary picture from a primary video signal or a secondary picture from one or more secondary video signal(s), the pictures from the primary video signal and the or all of the secondary video signal(s) being in an alternating sequence in picture display order of the received compressed bit steam. The received compressed pictures are identified as primary or secondary pictures and the received compressed pictures are compression decoded dependent upon the identification of the received compressed pictures.

摘要： A Video On Demand (VOD) system having a VOD catalog that lists VOD movies available for a user to purchase, a database for storing a plurality of reference images associated with the VOD movies in the VOD catalog, and an image processing and lookup system (IPLS) for searching the plurality of reference images in the database utilizing automated image recognition. A user takes a photograph of a movie poster or DVD box cover and sends the image to the IPLS. The IPLS determines whether the user image matches a stored reference image. If so, the IPLS sends an indication to the user that the movie associated with the matching image is available in the VOD catalog. When the received image does not match any image in the database, the IPLS sends an indication to the user that there are no movies in the VOD catalog matching the user image.
