Abstract
A channel map is created and/or edited with the aid of a PIP window in which a real time television program is displayed. The PIP window is displayed on a monitor screen at the same time as a channel map of pairs of network names and local channel numbers. The local channel numbers can be individually changed to create the channel map or edit the pairings of network name and local channel number. When the local channel numbers are changed, the tuner for the PIP window also automatically changes so the television program displayed in the PIP window corresponds to the television program telecast on the local channel number displayed on the screen. This provides verification of the accuracy of the pairing of network names and local channel numbers in the channel map.
