ELECTRONIC DEVICE IN ELECTRONIC DEVICE SYSTEM COMPRISING ELECTRONIC DEVICES CIRCULARLY CONNECTED EACH OTHER

摘要

PURPOSE: An electronic device of an electronic device system including a plurality of electronic devices, which is recursively connected, is provided to enable an electronic device to require transmission end and receiving end of a fewer numbers than using a two-way transmission channel, thereby largely reducing the whole system cost. CONSTITUTION: A first receiving unit(130) receives an uncompressed video signal from a first electronic device. A second receiving unit(230) receives a data signal from a first electronic device. A first transmitting unit transmits the uncompressed video signal to a second electronic device. A second transmitting unit(220) transmits the data signal to the second electronic device. If the signal received to the first and the second receiving unit, a control unit(110) performs operation corresponding to the signal. If it is not the operation object, the control unit transmits through a transmission unit corresponding to the signal.
