Telephone ring activation of a wireless transmitter for remote control of a television

An apparatus for use with a television, a wireless remote control unit for remote control of the television, and a telephone line carrying a signal, the apparatus comprising:

• a wireless transmitter that provides a wireless interface to the television;
• a wireless receiver that provides a wireless interface to the wireless remote control unit;
• telephone line interface circuitry, operably coupled to the telephone line, that receives the signal carried on the telephone line;
• control circuitry, operably coupled to said telephone line interface circuitry, said wireless receiver, and said wireless transmitter, that operates in first and second modes;
• and
• power-conversion circuitry, operably coupled to the telephone line, that converts electrical energy of the signal carried on the telephone line to an appropriate DC voltage level for powering on at least portions of the apparatus;
• wherein in said first mode, at least one user-supplied remote control command for updating audio volume settings of the television is communicated wirelessly from said wireless remote control unit to said wireless receiver and stored for subsequent use;
• wherein in said second mode, in response to receipt of the signal by the telephone line interface circuitry, the at least one remote control command stored in the first mode is transmitted wirelessly by the wireless transmitter to the television for effectuating remote control operations that update audio volume settings of the television in conjunction with the signal being carried on the telephone line;
• wherein said apparatus is powered by a battery in said first mode;
• and
• wherein said first mode is selected by disconnecting the telephone line from the apparatus and connecting the battery to the apparatus, and said second mode is selected by disconnecting the battery from the apparatus and connecting the telephone line to the apparatus.
