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.

Abstract: A cache is used to provide additional information to a recognition system about what words are likely to be used in a current context. Words are added to the cache only if they are explicitly corrected by the user. If the user forgets to correct (or postpones correcting) a recognition error, nothing is added to the cache, and therefore, there is no negative impact on the recognition system.
