The video player combines the video with the associated data that is available to the BBC, creating a much richer experience for its audiences, according to Perry : “Where we are able to show athlete performance data, the key thing is that we synchronise the data and video together so that you always see the stats appropriate for the point in the video that you are watching,” advised Parry. “So if you decide to watch a video from the start, we won’t give you the results from the end. And if you are watching live, we won’t show the result of the Men’s 100m before you’ve had a chance to watch it!”

This paper explores the opportunities and challenges of supplementing television broadcast channels with additional content using IP delivery. It looks at the way in which the additional material could be resynchronised with the broadcast content and what level of accuracy is required by different types of material.
It focuses on the use case of an alternative soundtrack to provide improved intelligibility for viewers who have difficulty understanding speech when presented with background sound. It then goes on to describe our demonstration system and discusses the opportunities for further research into hybrid delivery and the way it could enable a richer broadcasting landscape.

Timecode Systems is bringing the ground-breaking Timecode Buddy system to IBC 2012. As the first products to generate world-class accurate timecode with the ability to sync to iOS devices over WiFi, the Timecode Buddy: system is changing the future of timecode and throughput of metadata in film and television.

According to Julian Clover at Broadband TV News, KIT digital has implemented temporal tagging into its new suite of apps for RTE, the Irish public broadcaster who have picked KIT Cosmos cloud-based solution for future endeavors. Such an approach would work not only with broadcast and on demand content, but also radio.
Feargal Kelly, KIT digital’s VP of media solutions, says broadcasters need to move way from what he calls ‘passive second screen socialising’ to one that creates stickiness and increases viewer engagement with the content. “The level of misunderstanding of the second screen socializing purpose is so high, that some of the apps that allow viewers to message each other while watching TV are supplied by broadcasters and channel owners themselves,” he says.
Kelly says that rather than place watermarking within the video, as is the case with the Zeebox social media application, broadcasters should put effort into the backend as was the case with Red Button apps. By using metadata it becomes possible to sync content that is frame accurate.

While not mentionned as a use case, there is a good potential with second-screen situations where we need to get a precise timecode for the program.
