摘要：
The present invention provides technology for improving the convenience of information transmission and connection in the case of transmitting information by connecting together a plurality of pieces of video equipment (100, 200, 300). To that end, the present invention is one that transmits a baseband video signal and/or a compressed video signal between a first piece of video equipment (100) and a second piece of video equipment (200) by means of a bidirectional interface 10 and is characterized by the fact that the aforementioned bidirectional interface (10) has transmission rates that are asymmetric in the uplink and the downlink, narrowband information is transmitted in the downlink in case broadband information is transmitted in the uplink, and narrowband information is transmitted in the uplink in case broadband information is transmitted in the downlink.
