TRANSMISSION APPARATUS AND RECEPTION APPARATUS |
摘要 |
<p>A transmitting apparatus and a receiving apparatus that minimize a buffer's size without increasing the volume of data to memorize in the receiving apparatus. Data block making section 110 makes data blocks by dividing transmission on a per transmission unit basis. For each data block, CRC generating section 120 generates a CRC code, which is an error detection code. Transmitting section 130 transmits the data block multiplexing the CRC code upon the data block. RAM 140 temporarily memorizes the data block and the CRC code. Control signal receiving section 150 receives a control signal transmitted from receiving apparatus 200 to identify the next needed data block. When the control signal received in control signal receiving section 150 is one in request of the next data, control section 160 instructs transmission section 130 to send the next data block. When the control signal requests retransmission, an instruction is given to transmission section 130 to retransmit the data block and CRC code memorized in RAM 140.</p> |
