International ClassH04M 011/00AbstractAn in-home network which includes a telephone line and a plurality of consumer electronic devices coupled to the telephone line. Each of the consumer electronic devices is assigned a unique address, such that each of the consumer electronics devices is individually addressable via the telephone line. The consumer electronic devices communicate using a packet-based protocol, wherein each of the consumer electronic devices transmits analog signal bursts on telephone line. Each of the consumer electronic devices can include a wireless signal receiver, such that a first consumer electronic device can receive control information from a remote control, and then control the operation of a second consumer electronic device by transmitting the control information to the second consumer electronic device via the telephone line.Other References
