Decoder for a digital television receiver

Decoder for a digital television signal, which appears as a corresponding to the MPEG standard encoded data stream, which represents I, P and B pictures, for receiving and downsampling the size of a received data block in a data block of smaller size and outputting a processed data block with - a downsampling unit (142, 152, 81) for downsampling of original luminance information in the received data to a data block having a first predetermined size and for downsampling of original color information in the received data to a data block of a second predetermined size; - a motion compensation unit (146, 156, 88-89-90) for motion compensation of the down-sampled luminance and color information using the input motion vectors; - an adder (143, 153, 82) for combining the sampled luminance and color information of the downsampled with the motion compensated data; - a memory unit (144, 154, 86) for storing the combined data, - wherein the storage unit stores the combined data and the combined data as sampled data ...
