To provide a digital broadcast receiving system which allows viewing at any location in a house or a building without concern for installation location of a digital broadcast receiver while preventing deterioration of RF signals for digital broadcasting.

A radio frequency signal for digital broadcasting received by a television reception antenna 500 for digital broadcasting is demodulated by a digital broadcast distribution device 100, and transport stream packet data is extracted from the resulting digital data for digital broadcasting. The data is then modulated into radio frequency signals for a wireless LAN that are mapped to basic service set identifiers (BSSID) of an IEEE802.11 standard compliant wireless LAN, which are pre-assigned to digital broadcasting channels. The modulated signals are re-transmitted to one or more digital broadcast receivers 200 from a wireless access antenna 100a over a wireless LAN 300.
