Abstract
A decoder for converting packet data into raster data is provided. The packet data includes data about a picture-compressed video signal and data about a picture format including a picture rate. The decoder comprising a first processing means, second processing means and a storage means. The first processing means converts the packet data into intermediate data such that picture compression is eliminated from the picture-compressed video signal and outputs the intermediate data. The second processing means receives the intermediate data from the first processing means and processes the intermediate data to output raster data for one frame at a frame frequency. The storage means stores the intermediate data for processing the intermediate data in the second processing means. The second processing means writes the intermediate data into the storage means at a frequency related to the picture rate and reads the raster data for one frame from the storage means at the frequency equal to the frame frequency.
