    摘要: An image encoding and transmitting system is an image transmission system for transmitting digital data such as TV telephones.
    The system comprises on its receiving side an picture element domain frame data storage (24) for storing received data in the picture element domain, and a motion vector detector (25) for detecting according to the contents in the storage a motion vector using the data in the block surrounding the discarded block in order to guess the data in the discarded block.

    摘要: An apparatus for band compression processing of a picture signal which generates forecasting error signal (block 3) and movement vector (block 1) and updates only the movement vector during a comb-out operation. During comb-out processing, a picture signal is recirculated (block 5) while the movement vector is produced and accumulated (block 11). At the end of the comb-out processing, the change in the movement vector from the accumulated vector is within a desired range. Therefore, a scale of circuit does not increase for detecting the movement vector after the comb-out operation.

    摘要: A signal coding apparatus, which is coupled, via a transmission path (36), to a receiver having a receiver buffer (37) and a decoder (38), includes a coding unit (32) for coding a signal and outputting information generated in a frame unit, the information being a coded signal. The apparatus also includes a transmitter buffer (33) for temporarily storing the information, and a controller (34, 35) for controlling an amount of the information on the basis of a storage capacity of the receiver buffer and an amount of the information which is contained in a frame per a unit time. There is also provided a method used in the above coding apparatus, and a signal coding transmission system employing the signal coding apparatus.
