Inventor: KAGAWA TETSUYA
IPC: H04L1/18
Filed: 1988-07-25
Abstract: PURPOSE:To attain efficient communication by allowing the receiver side to inform the number of error bits in a data error to the sender side, allowing the sender side to decrease the number of times of retransmission at a high data transmission speed and to increase the number of times of retransmission at a low data transmission speed. CONSTITUTION:The receiver side informs an error bit number at MODEM training in terms of a CFR signal to the sender side and number of times of retransmission till shift-down at each data transmission speed is varied in response to the error bit number caused at the MODEM training in the case of repetitive execution of the retransmission of picture information. If the line state is deteriorated, since the error bit number is increased, the number of times of retransmission at a high data transmission speed is decreased and the repetition of the retransmission at a high speed apt to cause an error is reduced and the communication time is reduced.
