Patent ID: 7712119

Claim:
A multimedia receiving terminal provided with a first unit that receives a coded bit stream of information transmitted at a predetermined error resilience level, which is adjusted based on an observed transmission error rate, by a transmitting terminal through a communication channel and a second unit that decodes and displays the received bit stream, comprising: a third unit that evaluates the error resilience of information received by the receiving terminal and compares the error resilience with a predetermined setting related to the error resilience of the coded bit stream transmitted by the transmitting terminal; and a fourth unit that transmits, to the transmitting terminal through the communication channel, a request to change the error resilience level of the coded bit stream transmitted by the transmitting terminal, wherein if the transmission error rate is higher than the predetermined setting, the fourth unit transmits a request to raise the error resilience level of the coded bit stream transmitted by the transmitting terminal, and wherein if the transmission error rate is lower than the predetermined setting, the fourth unit transmits a request to lower the error resilience level of the coded bit stream transmitted by the transmitting terminal to improve the quality of a coded image.
