Multimedia input and control apparatus and method for multimedia communications
First Claim
1. An apparatus for multimedia input and control, the apparatus comprising:
- a video input to produce an input video signal;
an audio input to produce an input audio signal;
a radio frequency modulator coupled to the video input and the audio input;
a data/control input to produce an input data signal; and
a processor arrangement coupled to the video input, to the audio input, to the radio frequency modulator, and to the data/control input, the processor arrangement responsive when operably coupled, through a set of program instructions, to produce a first processor signal to the radio frequency modulator to combine the input video signal with the input audio signal to form a composite audio/video signal, the processor arrangement further responsive to modulate the input data signal to form a modulated input data signal and produce a second processor signal to the radio frequency modulator to combine the input video signal with the modulated input data signal to form a combined video/data signal.

Abstract
An apparatus (300, 400) and method are provided for multimedia communications, such as for video conferencing. One of the embodiments of the apparatus for multimedia input and control (300) includes a video input (310) to produce an input video signal; an audio input (320) to produce an input audio signal; a radio frequency modulator (350); a data/control input (330) to produce an input data signal; and a processor arrangement (360) responsive when operably coupled, through a set of program instructions, to produce a first processor signal to the radio frequency modulator to combine the input video signal with the input audio signal to form a composite audio/video signal, and the processor arrangement (360) further responsive to modulate the input data signal to form a modulated input data signal and produce a second processor signal to the radio frequency modulator to combine the input video signal with the modulated input data signal to form a combined video/data signal.
