Abstract
In a method of recording video information in a record carrier, each picture of N.times.M picture elements being divided into subpictures of n.times.m picture elements, the video information of each subpicture is encoded in accordance with a transform coding and recorded on the record carrier. Moreover, corresponding subpictures of two pictures are compared with each other. To both subpictures a motion code is assigned, which motion codes are the same if the subpictures do not differ substantially from one another, but which are not the same if the subpictures differ substantially from each other. The motion is recorded on the record carrier together with the coded information of the subpicture. Moreover, different transform codings may be applied to the subpictures. A higher-order transform coding yields a more accurate information of the subpicture which is encoded. The associated transform code is also recorded on the record carrier. Further, a method of reproducing video information from the record carrier is described and apparatuses for carrying out the two methods are described.
