DVB-GEM v1.3 Published

DVB has approved the latest version of its specification for interactivity â Globally Executable MHP (GEM). This new version of GEM v1.3 prepared by the ad-hoc group TM-MUG, chaired by Michael Lagally (Oracle), now provides support for Over-The-Top (OTT) television and Hybrid Broadcast/Broadband (HBB). This new version of the Java based GEM specification defines an OTT device category (target), which addresses media distribution over broadband networks without guaranteed bandwidth such as the Internet. The OTT target complements the existing GEM targets for Broadcast, Packaged Media and IPTV.

The OTT target offers new APIs to address particular OTT scenarios for content streaming and download and can be used for adaptive streaming deployments. For hybrid broadcast/broadband deployments GEM 1.3 offers API enhancements to synchronise media content over different networks. This feature can be used to offer, for example, additional subtitle languages or audio tracks for broadcast content.
