MPEG-DASH and Hybridcast

摘要

Twenty-four broadcasting stations have started offering Hybridcast services, and approximately 4 million Hybrid-cast receivers have been sold since its launch in September 2013. Hybridcast's application engine is an open HTML5 platform that reduces the costs of developing TV receivers and applications and makes it easy for the server and TV receiver to work together in performing complex application processes. These features greatly contribute enhancements of the functions of the integrated broadcast-broadband services. Moreover, the addition of a Video-On-Demand (VOD) standard that supports MPEG-DASH (Dynamic Adaptive Streaming over HTTP) has opened up possibilities for new services that harmonize services across broadcasting and broadband. This article describes how MPEG-DASH is handled in the Hybridcast Technical Specification Version 2 published by IPTV Forum Japan. It also discusses the use of MPEG-DASH media players and other applications involving MPEG-DASH in Hybridcast services.
