New Broadcasting Technologies Utilizing Broadband


Synchronization Technology for Broadcast Programs and Internet Content

Taking Hybridcast to the next level


To give Hybridcast a higher level of functionality, we are working on technologies to synchronize Internet-based content with broadcast programs. Below is an example of how we can customize live sports coverage by offering additional features via the Internet, such as alternative camera footage and various data corresponding to the on-going game, to give viewers more excitement and a better understanding of the content they are watching.


●Synchronizing video shown on television and mobile devices

We have developed a way to synchronize streamed video on mobile devices with programs broadcast over the air. It sends reference clock data from the broadcast signals to a mobile device, such as a tablet, to enable it to synchronize the streaming video with the broadcast.

●Synchronizing broadcast program and real-time data

During live sports coverage, various real-time data are sent over the Internet. Our technology coordinates broadcast reference clocks with real-time UTC (Coordinated Universal Time) to accurately synchronize data with broadcasts and overlay it on television screens.

●Prototype Hybridcast receivers with the latest synchronizing technologies

In June 2014 the IPTV Forum Japan released the Hybridcast Technical Specifications ver2.0*, which includes a new feature to synchronize broadcasts with Internet content. A new clock-acquisition API has been installed on the prototype receiver used in our demonstration.

Future plans

We will conduct tests over the Internet and research on minimizing the distribution and display latency. We will also work on laying out operational rules to make this synchronization functionality a part of commercially available receivers.

* Hybridcast Technical Specifications ver2.0 comprises IPTV Forum Japan’s standard STD-0010 broadcast-internet coordination system specifications ver2.0
 and STD-0011 HTML5 browser specifications ver2.1.
