Monitor control circuit using wireless headphones and method therefor
First Claim
1. A circuit for controlling a computer monitor receiving a speaker input signal, said circuit comprising:
- wireless headphones for outputting a first control signal based on a user input command;
a radio transceiver for generating a second control signal based on the first control signal from said wireless headphones;
a first microcomputer for generating a switching control signal according to the second control signal from said radio transceiver; and
switching means for receiving the speaker input signal and selectively outputting the received speaker input signal to said radio transceiver as a controlled audio signal for transmission to said wireless headphones or to an audio amplifier in said monitor for driving a speaker, according to the switching control signal from said first microcomputer.

5. A method of controlling a computer monitor, comprising the sequential steps of:
-
sensing a remote control signal output from wireless headphones; determining which one of a plurality of control signals said remote control signal corresponds to when the remote control signal is sensed; and controlling power of said computer monitor or selectively outputting an audio signal to the wireless headphones or a speaker of the computer monitor depending on which one of said plurality of control signals said remote control signal corresponds to in said determining step. - View Dependent Claims (6, 7, 8, 9)

10. A computer monitor control circuit, comprising;
-
a wireless headphone unit connected to a set of headphones, said wireless headphone unit comprising; means for inputting user commands; means for converting said user commands to a remote control signal; means for converting said remote control signal to an optical remote control signal; means for receiving a controlled audio signal transmitted optically from a computer monitor; and means for converting said controlled audio signal to a sound signal for output through said set of headphones; said computer monitor comprising; means for generating a pre-amplified audio signal by pre-amplifying an audio output signal received from a sound card of a computer; a radio transceiver for receiving said optical remote control signal from said wireless headphone unit, for converting said optical remote control signal into control data and for transmitting said controlled audio signal to said wireless headphone unit; means responsive to said control data for outputting a monitor power control signal for controlling power of said computer monitor and for generating a speaker mode selection signal; a speaker connected to said monitor; means for driving said speaker; and a speaker mode switch responsive to said speaker mode selection signal for selectively outputting said pre-amplified audio signal to said radio transceiver or to said means for driving said speaker. - View Dependent Claims (11, 12, 13)
