The television receiverreceives function information, whereby whether or not the disk recorderis an eHDMI-compatible device can be determined, and in the case of an eHDMI-compatible device, a compatible transmission format (application) can be recognized. It can also be conceived to transmit the function information from the television receiverto the disk recorderin the same way as described above.
