I'm going to guess that the Panasonic uses TV Guide Onscreen, which is
also built into my Sony HX900. The unit acquires the information from
whichever local TV station/stations is/are sending it within their 
broadcast signal. (Let me guess--on line 21 of the vertical blanking 
interval? That seems to be where everything else [closed captioning; 
XDS program names, channel names, times, etc.] is stuffed. :-) )
