Abstract
Upon completion of decoding by a first decoding part 14, a first identification signal indicative of permission or inhibition of transmission of the next data is sent to a packet transmitting device.
Claims9
A packet transmitting device provided with:
- transmitting means that transmits data to a packet receiving device;
- first control means that receives a first identification signal sent from said packet receiving device and, when the first identification signal is indicative of permission of transmission of the next data, instructs said transmitting means to transmit the next data and, when the first identification signal is indicative of inhibition of transmission of the next data, instructs said transmitting means to retransmit the data concerned;
- and second control means that receives a second identification signal sent from said packet receiving device and, when the second identification signal is indicative of success in decoding, discards the data concerned and, when the second identification signal is indicative of failure in decoding, instructs said transmitting means to retransmit the data concerned.
A packet receiving device provided with:
- receiving means that receives data sent from a packet transmitting device;
- decoding means that decodes the data received by said receiving means;
- and identification signal generating means that sends a first identification signal indicative of whether to permit or inhibit transmission of the next data to said packet transmitting device prior to completion of data decoding by said decoding means and sends a second identification signal indicative of whether the data decoding by said decoding means is successful or not to said packet transmitting device after completion of the decoding.
A packet transmission system provided with:
- transmitting means that transmits data;
- receiving means that receives the data sent from said transmitting means;
- decoding means that decoding the data received by said receiving means;
- identification signal generating means that sends a first identification signal indicative of whether to permit or inhibit transmission of the next data to the packet transmitting device prior to completion of data decoding by said decoding means, and sends a second identification signal indicative of whether the data decoding by said decoding means is successful or not to the packet transmitting device after completion of the decoding;
- first control means that receives the first identification signal sent from said identification signal generating means and, when the first identification signal is indicative of permission of transmission of he next data, instructs said transmitting means to transmit the next data and, when the first identification signal is indicative of inhibition of transmission of the next data, instructs said transmitting means to retransmit the data concerned;
- and second control means that receives a second identification signal sent from said identification signal generating means and, when the second identification signal is indicative of a success in decoding, discards the data concerned and, when the second identification signal is indicative of a failure in decoding, instructs said transmitting means to retransmit the data concerned.
