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).

A method for managing the detection of advertising sequences in a stream of information stored on a mass memory module of an electronic apparatus, the information stream corresponding to an extract of a television program, the information stream including a first set of information corresponding to a content to be rendered and a second set of information, corresponding to the advertising sequences, the information stream including at least one set of video information, and teletext type data, and subtitle data associated with the stream, the method including analyzing the video information for detecting a format transition in the images associated with the video information; optionally storing a first address information corresponding to the detected transition, and validating a first detection condition; analyzing the teletext type data for detecting an absence, and then a presence, of teletext subtitles associated with the video information, optionally storing a second address information corresponding to the detected, transition, and validating a second detection condition; analyzing the subtitle data associated with the stream for detecting an absence, then a presence of the subtitle data associated with the stream; optionally storing third address information corresponding to the detected transition, and validating a third detection condition; if the three detection conditions are validated, identifying the stored address information as transition sequences between the second set of information and the first set of information.

The present invention provides a password fuzzy input method comprising the steps of: displaying a plurality of teletext regions by virtue of a user interface, wherein each teletext region has a mapping relationship with an information unit consisting of a plurality of information elements; detecting direction information of a gravity sensor, and changing the display view angles of the teletext regions in the user interface by following the changes of the direction information to ensure that the teletext regions show a plurality of teletext layers thereof in equally-spaced overlapping arrangement, and each teletext layer displays one of the information elements of the information unit in the teletext region where the teletext layer belongs to; and responding to a user defined instruction of any one of the teletext regions, and selecting the information unit mapped with the teletext region so as to verify whether the content of a corresponding position of a preset password is one of the information elements in the information unit. The present invention provides a corresponding password fuzzy input device at the same time. While improving the fuzzy degree of the password input process, the method provided by the present invention enhances the interactivity of the interface and improves the user experience.

A technique to provide a cost effective solution to detect teletext data that can reduce detected error in teletext when the transmission data rate is known. In one example embodiment, this is accomplished by detecting data bits in an unsynchronized digital data stream by finding start of each data bit based on an estimated data bit width and transitions in the unsynchronized digital data stream.
