Method, system and recording medium using a relay device for detecting and inhibiting communication

A method of relaying a signal by a relay device including a first signal reception unit, a first radio communication unit, and a second radio communication unit provided separately from said first radio communication unit capable of both transmitting/receiving signals by radio, comprising the steps of:

• receiving a first signal from the outside by said first signal reception unit;
• further transmitting said received first signal by said first radio communication unit;
• detecting a transmission/reception of a second signal by said second radio communication unit;
• and
• inhibiting, during a period in which said transmission/reception of said second signal by said second radio communication unit is detected, transmission of said first signal by said first radio communication unit,
• wherein at least said first radio communication unit and said second radio communication unit are configured in a single assembly, and
• wherein said first signal and said second signal are different types of signals, including video signals and LAN signals.

A computer-readable recording medium having a relay program recorded thereon, said relay program being executed by a relay device including a first signal reception unit, a first radio communication unit, and a second radio communication unit provided separately from said first radio communication unit transmitting/receiving signals by radio, and said relay device executing said relay program to perform the steps of:

• receiving a first signal from the outside by said first signal reception unit;
• further transmitting said received first signal by said first radio communication unit;
• detecting said transmission/reception of a second signal by said second radio communication unit;
• and
• inhibiting, during a period in which said transmission/reception of said second signal by said second radio communication unit is detected, transmission of said first signal by said first radio communication unit,
• wherein at least said first radio communication unit and said second radio communication unit are configured in a single assembly, and
• said first signal received by said first signal reception unit and said signals transmitted/received by said second transmission/reception unit are different types of signals, including video signals and LAN signals.
