    摘要： A digital signal processing apparatus which is used for the computation of coding image signals or the like and a motion compensative operation method which uses a digital signal processing apparatus. The apparatus comprises a plurality of signal processing means arranged in parallel and control means which assigns loads to the signal processing means so that the signal processing means have even computation volumes. Alternatively, an address generator is provided for each of data sets entered independently. An intermediate check is conducted during the computation for a block which involves a motion compensative operation.

    摘要： In a multimedia information processing system, a relay station (201) comprises: transmission decoding section (500) for reproducing a fixed packets stream (14) from received transmission signal (15) from a transmitter (1001); signal change processing means (900) for executing changing process for the fixed packets stream (14); and transmission coding section (400) for producing a transmission signal (15) corresponding to a characteristic of a transmission line from the fixed packets stream (14). The construction for exchanging signals between different transmission means is simplified. Thus, it is achieved to exchange contents of media between different transmission means by a simple construction.
