ABSTRACT:
An apparatus automatically sets a specific number for video equipment corresponding to a cable box which is connected to the video equipment. The cable box outputs an externally supplied cable broadcasting signal if its stored specific predetermined number is identical to cable box number supplied by the apparatus. The apparatus has a sync detector which receives an output of the cable box and generates a sync detection signal indicating whether a sync signal of a video signal is detected. A controller stores a plurality of predetermined cable box numbers, and outputs each of the predetermined cable box numbers sequentially to a cable box in response to the sync detection signal supplied from the sync detector. If the sync detector detects a sync signal, the controller sets a specific number of the installed cable box corresponding to the number which was output. Thus, the specific number of the cable box is automatically set in the video equipment.
