Hybrid delivery of Television; Integration of Broadcast and Broadband for Interactive Media
Resumen de la conferencia/Conference Abstract
Traditional media delivery was a one-way communication scheme which predominantly relied on radio frequency based transmission. It provided little opportunities for interaction due to lack of an integrated return channel. With the increased penetration and advancements gained by the broadband, over the air delivery can make use of broadband as a return channel to interact with the media services. There are a number of technologies and standards available which offer hybrid or integrated broadband broadcast services. They complement the broadcast services.
Until recently, when media to be consumed via online services such as catch-up TV or video on demand, the user had to do it on a personal computer or laptop. Now, with a Connected TV it is possible to access content from the comfort of your living room and watch your favourite shows on the television.
In Asia-Pacific region, Australia and New Zealand have already introduced hybrid service known as Freeviewplus. Freeviewplus is a new hybrid television service which integrated with broadband in 2014 and 2015 respectively. A few more countries in Asia-Pacific are following a similar approach by introducing hybrid broadcast-broadband augmenting their DTT services. The hybrid broadcast-broadband platform is based on a technology engine known as HbbTV, whose specifications revised in early 2015. Malaysia is planning to use the HbbTV as hybrid engine for its digital terrestrial television broadcast service to be introduced during 2016.
This presentation will refresh and clarify the concepts such as IPTV, OTT, VoD and Internet TV. It will then highlight and provide an overview of technologies available for hybrid media services. The presentation will also explore numerous services that could be offered using broadband including over-the- top services that both new and incumbent broadcasters could offer.
