AI Technical Summary

Problems solved by technology

The timing in the original signal is also interrupted, which creates a potential problem, since many receivers are not sophisticated enough to handle the interruption, they either cannot react fast enough, or they assume the interruption is an error (of course since the broadcast signal may be affected by Atmospheric and Temporary Reflections) while specifying a period of time to wait for the time base to recover
This makes it difficult to synchronize interactive applications

Embodiment Construction

[0018] exist figure 1 In , the activities of broadcasters, publishers and end users are indicated at 10, 12 and 14, respectively. Only one issuer 12 is illustrated, but in many cases there are other issuers and / or network operators in the issue chain.

[0019] In this embodiment, the broadcast signal generator has a multiplexer 16 . It multiplexes a video component 18 , an audio component 20 and a data component 22 with an identification signal 24 generated by a device 26 to generate a broadcast signal 28 . Data components 22 contain interactive applications in most cases. Included in the data component 22 is a time base 23, which is a periodic clock inserted into the data component 22 every 1 second.

[0020] Interactive applications generally relate to the content being broadcast. For example, if the broadcast content is a golf tournament, the interactive application may contain statistics for the golf tournament participants, a hole-by-hole map of the course, or an inte...

Abstract

A method of monitoring a broadcast signal (28) comprises receiving a broadcast signal (28), the broadcast signal including a timebase (23), monitoring the broadcast signal (28) for an identification signal (24), and pausing the timebase (23) if the identification signal (24) is not present. The method further comprises restarting the timebase (23), once the identification signal (24) is present.

Description

technical field [0001] The present invention relates to methods and apparatus for monitoring broadcast signals. Background technique [0002] In traditional analog broadcast television, video and audio signals are broadcast over a wide area to be received by appropriate devices within that range. Data in the form of teletext can also be sent in analogue systems, the teletext data being effectively hidden within the video signal in a predetermined manner. A receiving device in an analog system strips out the teletext data from the signal, and the teletext data can then be accessed by the user through the user interface of the television used by the user. This allows simple text pages to be broadcast. [0003] More recently, with the innovation of digital television, broadcast systems have been designed such that the transmitter broadcasts three different signal components. These signal components are the video, audio and data components of the signal. By having a predeter...
