Title:
幾つかのEPGソースを1つの信頼性のあるEPGに合成するシステム及び方法
Document Type and Number:
Japanese Patent JP2004538725
Kind Code:
A
Abstract:
The present invention relates to a device for acquiring electronic program guide (EPG) data from a plurality of different EPG sources (120), and combining the acquired data to a single EPG (10). At regular intervals, EPG data is acquired from different sources (120), which may include the Internet (122), digital programming broadcasters, and teletext service providers (126). Equivalent program listings (40) within the acquired EPG data are identified, and the best information is selected from the equivalent program listings (40) to be included in the combined EPG (10). The present invention is able to identify equivalent program listings (40), even if the program titles are written in different languages or when the scheduled broadcast times differ to some extent. The resulting EPG (10) is more reliable and contains more information than any of the EPGs (10) associated with the original sources (120).
