Abstract
The invention makes it possible to draw lots for a present in real time in association with a broadcast program. A broadcasting station broadcasts information relating to lot for a present that is associated with a broadcast program by superimposing it on a video signal in vertical blanking intervals. The lot information is decoded by a decoder and viewed by a viewer on a TV receiver. When the viewer commands the decoder to enter the lot for the present, the decoder accesses a present call center and an automatic lots-drawing system draws lots. A drawing result is transmitted to the broadcasting station and announced during the broadcast of the program. A sponsor sends the present product to winner viewers based on winner data.
