Aligning video data to create a comprehensive program guide |
摘要 |
Providing content listings for digital television broadcasts. A computing device matches digital broadcast television channel data (e.g., call signs or broadcast frequencies) with analog broadcast television channel data to create a list of mapped channels. The computing device creates a program guide for the digital broadcast television channels as a function of the matched channel data by associating program listings for the analog channels with the digital channels. The created program guide covering both digital and analog television channels is stored in a database for subsequent processing responsive, for example, to a user request. In one embodiment, the digital broadcast television channels conform the Advanced Television Systems Committee (ATSC) standard. |
