A method and apparatus is disclosed for remotely processing voice commands
for controlling a television. A voice command is uttered by a user into a
microphone contained in a remote control. The voice command is digitized,
modulated, compressed, and wirelessly transmitted to a wireless receiver
connected to a set-top box. The voice command is then transmitted to a
cable head-end unit for voice and word recognition processing. Once the
command function is determined, the function is transmitted back to the
set-top box where the set-top box performs the command. The microphone is
activated and deactivated by pressing and releasing a push-to-talk (PTT)
switch. The PTT activates other functions by being turned, double-clicked
and toggled up and down, left and right.
