Embodiment Construction
[0016] In order to make the object, technical solution and advantages of the invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.
[0017] It should be noted that the preferred embodiments of the present invention described below are actually only exemplary implementations of the present invention, rather than limiting the present invention and the application or use of the present invention.
[0018] The systems and methods described in the present invention can be used in a wide variety of different applications, figure 1 An exemplary application in an interactive television environment is provided. Such as figure 1 As shown, a television 10 and its associated set-top box 12 receive a modulated signal from a broadcast source 14 . Typically, the signal is modulated onto a different channel and the set top box 12 is tuned to the channel carrying the modulated signal. Alternatively, a dig...

A system and method for supplying media content from disparate sources includes tagging media content with an identifier tag useful in synchronization with additional media content, and useful in delivery of the media content. In other aspects, the media content is transmitted to a distribution mechanism (23) adapted to distribute the media content to media delivery devices (20). In yet another aspect, the media delivery device is adapted to obtain additional media content from a disparate source (14,16), adapted to synchronize the media content with the additional media content according to the identifier tag, and adapted to deliver the media content to a consumer according to the identifier tag.
Description
technical field [0001] The present invention relates generally to interactive television and multimedia systems. More particularly, it relates to an authoring system and method for providing tagged media content, said authoring system and method enabling handheld (Handheld Device) devices communicating with broadcast sources and other information sources to synchronize information received . Background technique [0002] Interactive television holds great promise as the information delivery system of the future. However, at this stage it still leaves many problems to be solved. Currently, there are many ways to implement a multimedia experience. One method focuses on using broadcast media such as broadcast television media as a basic information channel and adding interactive capabilities to the above broadcast media. Another approach advocates the use of packet-based media delivery channels such as the Internet that will support both streaming video and the interactive ...
