TELEVISION SYSTEM WITH OUTPUT POWER SAVING FUNCTION

摘要

A digital television system capable of controlling the supply of output power is provided. The digital television system includes a sound signal supply unit which processes digital signals received from an external source and generates digital audio signals; a sound signal processor which receives and converts the generated digital audio signals to analog audio signals and outputs the analog audio signals; a power supply unit which supplies electric power to the sound signal processor; a digital output terminal outputs the digital audio signals from the sound signal supply unit; and a controller which controls the power supply unit to terminate a supply of electric power to the sound signal processor if the digital output terminal is connected to an external device.
