Patent

CA 2145218

An apparatus is disclosed for processing video information using a first and a second prediction filter circuit which are substantially identical, and a control signal to process video information encoded in multiple standards. A filter circuit, such as may be used in such an apparatus, for use in video decompression comprises a prediction filter formatter, a first one-dimensional prediction filter, a dimension buffer, and a second one-dimensional prediction filter. A prediction filter, such as may be used in such a filter circuit, may comprise six registers, two multiplexers, and two summing circuits. A first register is connected to a first summing circuit. A second register is connected to a first multiplexer, which is connected to the first summing circuit. The first summing circuit is connected to a third register. A fourth register is connected to a second multiplexer, which is connected to a fifth register. The third register and the fifth register are connected to a second summing circuit, which is connected to a sixth register.
