Content Delivery

Facilitating Content Consumption
Whatever the Platform

The Internet, mobile communications and broadcasting
are converging. But the standardisation of these
different areas has traditionally followed different paths,

We are addressing the urgent need to align the diverse
specifications for content delivery in a converged
environment supporting Internet Protocol Television
(IPTV), Mobile TV and broadcast TV – for the benefit of
both the industry and the consumer.

In the radio area, the JTC simplified the Digital Audio

original DAB audio coding to the more efficient DAB+ audio
coding, the JTC took the opportunity to remove DAB audio
