ABSTRACT:
In order to achieve a qualitative improvement of television images through increased image frequency with simultaneously increased resolution, a high storage capacity is needed. In order to process a combined color television signal, a demultiplexer with a shift register to which the data stream of the color television signal is fed is employed. Parallel outputs from this shift register are connected to a storage. Additionally, a second and third shift register are present whose parallel inputs are connected in the storage and from whose serial outputs the individual components of the color television signal can be obtained. Further, a sequence controller consisting of address counters is used to individually access rows and columns of the second and third shift registers. The invention simplifies the use of storage for digital signal processing in color television sets.
