20080313683 | MOVING IMAGE COMMUNICATION DEVICE, MOVING IMAGE COMMUNICATION SYSTEM AND SEMICONDUCTOR INTEGRATED CIRCUIT USED FOR COMMUNICATION OF MOVING IMAGE - A communication processor sets a storage request signal to be effective when it is judged that a packet cannot be transmitted and sets the storage request signal to be ineffective when it is judged that the packet can be transmitted. A data processor makes a buffer memory store encoded data therein when it is confirmed that the storage request signal is effective. The data processor reads the encoded data from the buffer memory and transmits the read encoded data to a packet generator when it is confirmed that the storage request signal is ineffective and the encoded data is stored in the buffer memory. The data processor receives the encoded data from the encoder and transmits the received encoded data to the packet generator when it is confirmed that the storage request signal is ineffective and the encoded data is not stored in the buffer memory. | 12-18-2008 |
