Embodiment Construction

[0024] Referring now to the accompanying drawings, figure 1 An embodiment of an electronic program guide (EPG) 10 is shown. An EPG 10 typically displays one or more program listings 40, each program listing 40 providing information about a particular program broadcast over a communication medium to a plurality of output devices. The information provided by the program listing usually includes at least the program title. This information may also include when the program will air, who will perform in the program, a synopsis of the program, the type and category of the program, and other information describing the content of the program.

[0025] EPG 10 may include program listings for television programs, Internet broadcasts, or radio programs. As discussed above, television programs may be transmitted via television antenna signals, cable, satellite, or other types of communication media. Radio programs may be broadcast via radio signals or, in some cases, over the Internet...

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).

Description

technical field [0001] The present invention relates to an electronic program guide (EPG), and more particularly to a system for extracting and combining EPG information from multiple sources to create a more reliable EPG. Background technique [0002] Over the past 20 years, due to the development of broadcasting technologies such as cable TV, satellite TV and other digital TV systems, the number of programming choices available to TV viewers has increased dramatically. Today, many television viewers may choose from hundreds of television channels. In addition, television is no longer the only medium for broadcasting programs. Internet webcasting, in which a data stream delivering a multimedia program is broadcast to multiple personal computers, is becoming increasingly popular. [0003] Printed program guides, such as those published in newspapers and periodicals, are often insufficient to provide viewers with all the information needed to choose from these large numbers...
