Remote editing is carried out between video apparatuses connected via a communication network without producing deviation between transmitted audio and/or video and time code data. An editing machine 18 outputs a time code sense command to a terminal equipment 12, and the terminal equipment 12 multiplexes the time code sense command in a transmission packet and transmits the same to a terminal equipment 42 via a communication network 30. The terminal equipment 42 receives the transmission packet, demultiplexes the time code sense command, and outputs the same to a VTR apparatus 46. The VTR apparatus 46 outputs the audio and/or video data and the time code data to the terminal equipment 42 according to the control data. The terminal equipment 42 multiplexes the audio and/or video data and time code data input from the VTR apparatus 46 in the transmission packet and transmits the same to the editing system 10.
