PURPOSE:To improve line utilizing efficiency by taking burst synchronization synchronously with a detection timing of a frame synchronizing signal, recovering a digital subcarrier signal and sending an incoming data synchronously with the recovered clock. CONSTITUTION:Upon the receipt of a television signal TS', a time division multiple access(TDMA) transmission section of each slave station 111-1mn detects a frame synchronizing signal FC for burst synchronization from a subcarrier signal of the TV signal and sends a data burst DU11-DUmn of the incoming data in the timing assigned to its own station in the TDMA frame synchronously with the detection timing. That is, the burst synchronization frame synchronizing signal FC is used as a reference burst of the TDMA frame to send a data burst. Thus, a time slot for reference burst transmission is not required on the TDMA frame and the time slot is assigned for sending the data burst. Thus, the line utilizing efficiency is improved. |
