M-todos e sistemas para proporcionar informa-Æo para uma televisÆo utilizando um compustador pessoal

摘要

A personal computer is used to download and process auxiliary services which are intended for a television. Accordingly, information is provided to a television using a personal computer, so that the personal computer's processing power and memory may be used rather than stand-alone devices or a television memory. An external network interface is provided in the computer, as well as a low power television transmitter or transceiver. A unified television/personal computer remote control provides personal computer commands to the personal computer via radio frequency signals. Television commands may be provided to the television directly using infrared signals or indirectly through the personal computer using radio frequency signals. When television commands are provided using radio frequency signals, an infrared converter is provided for the television, to convert the radio frequency signals to infrared signals.
