    摘要: A digital broadcasting receiving apparatus that can be installed without regard to the location of the telephone outlet where a signal is received by a front-end, reception data is decoded by an A/V decoder, and a video signal and an audio signal are outputted from a D/A converter. Monitor information has been stored in an IC card and is periodically read into a memory by a CPU. Further, the monitor information is transmitted from the memory to a management system by the control of the CPU through a telephone line. A modem and a slave module of a cordless telephone are connected. The monitor information is transmitted between the slave module and an external master unit in a wireless manner. The monitor information is transmitted from the master unit to the management system through the telephone line.
