Abstract (en)
[origin: WO9715146A1] A method of encoding video images is disclosed, in which different coding methods are applied to different regions of the image. The image is divided into blocks, and the coding method which is optimal in a rate-distortion sense is selected (2) for each block. In an embodiment, transform coding (3), such as DCT or LOT, is applied to all blocks. The block size is selected in accordance with a rate-distortion criterion.
