Decoder and method for decoding of coded picture-, video- and film information

Decoder for decoding datastreams of picture-, video- and film information comprising

• a data processor (302) for decoding a datastream and for processing a block to raster conversion (BRC),
• signal processing means (303) for processing digital picture signal processes, wherein said processes comprise inverse quantization (IQ), inverse cosine transformation (IDCT), frame reconstruction (FR) and optionally color space conversion (CSC),
• internal memory (304-306) comprising a plurality of RAM segments having independent access to each other,
• a memory interface (307) for accessing an external memory,
• control unit means (301) for controlling said data processor (302) and said signal processing means (303),
• wherein the data processor (302), the signal processing means (303) and the internal memory (304-306) are connected to the memory interface (307), and wherein
• the signal processing means (303) comprises arithmetic units and a multiplexer connected with each other for processing said IQ, IDCT and FR and optionally CSC, wherein the signal processing means (303) is not a program controlled central microprocessor (CPU),
• the signal processing means (303) further comprising process control means for controlling the digital picture signal processes independently from each other responsive to the control unit means (301),
• the control unit means (301) coordinating the digital picture signal processes for sending start signals to the signal processing means (303) responsive to the process control means, and
• the decoder having exactly one means for signal processing (303) comprising exactly one multiplier.
