A method and a means for coding and decoding picture information is described. According to prior art two modes are utilized for transmitting picture information, with prediction and without prediction, respectively. According to the present invention advantages are obtained in using a mixed mode, i.e. certain frequency components are transmitted with prediction and the remaining components without. In the invention two channels are utilized, with and without prediction, respectively, these channels being selectively connected by means of switches, which are controlled by a control means. |
