Premium channel promotion system and method |
摘要 |
The present invention is directed to a television schedule guide which includes a detector for determining whether a previously scrambled program is unscrambled. If a previously scrambled program is momentarily unscrambled due to promotional efforts by the program provider, the system will visually distinguish the program on the guide, and a viewer may tune to or record the program from the guide. The view may also subscribe to the program provider through the guide during the promotional period.
