WIRELESS RECEIVER DEVICE, WIRELESS COMMUNICATION SYSTEM AND ANTENNA INSTALLATION SUPPORT METHOD

摘要

Disclosed is a television (10) provided with: a WiHD-RX (11) that receives signals sent from a camcorder (20) and a BD system (30) over the respective antennas thereof; a direction detector (102) that detects information showing the relative positions of a WiHD-TX (21) and a WiHD-RXTX (31) with reference to the position of the WiHD-RX (11); a communication state acquisition unit (104a) that acquires communication state information showing whether or not a video or audio signal can be transmitted between the camcorder (20) and the BD system (30), and an update information generation unit (104b) which, if said communication state information shows that transmission is not possible, generates, based on the detection results from the direction detector (102), and outputs update information showing the direction in which the transmission range (the range in which video or audio signals can be transmitted from the WiHD-TX (21)) extends towards the WiHD-RXTX (31).
