Channel Browser - (Interactive Channel Browser) - With this, a display comes up that contains thumbnail size (roughly the size of big stamps) views of what's on each channel at that moment.  The viewer using their remote control (or another form of interactivity) can click on whichever channel he/she wishes for a full screen display (complete with audio) of that channel. Channel Browsers fall in the general category of TV Mosaics. Also see Interactive Program Guides.
