Abstract
Until the present, the digital television (DTV) industry has focused providing high—quality basic video and audio services. With advancements in the underlying technologies, digital television is likely to evolve into a much more interactive medium, involving advanced data services and applications which are both integrated with and synchronized to the video/audio content of the broadcast. We present our approach for the implementation of these synchronized data services, with emphasis on the issues of content synchronization and the optimization of data placement in the broadcast stream.
