MMT, New Media Transport Technology

For harmonization of 8K broadcasting and broadband

Outline

We are studying media transport technologies to provide hybrid 8K Super Hi-Vision (8K) broadcasting services enhanced with information from broadband networks. This exhibit shows examples of hybrid services using the transmitters and receivers supporting MMT*.

Features

●Advanced broadcasting services enhanced with broadband networks

With the use of MMT, TV programs can be transmitted using the same mechanism for both broadcasting and broadband. It allows information transmitted through different channels to be easily presented in synchronization with each other on a display.

●Presentation of content suited to individual viewers

MMT enables seamless switching between a program received from broadcasting and a program received from broadband. This enables the presentation of videos tailored to the needs and interests of individual viewers, for example, by presenting program advertisements suited for their needs.

●Development of a transmitter/receiver supporting MMT

We have developed a transmitter/receiver for MMT-based transmission of video and audio signals. This device is compliant with ARIB STD-B60, a Japanese media transport scheme standard for 8K broadcasting.

Future plans

We are going to conduct transmission experiments using the transmitter/receiver we developed in various environments and verify hybrid 8K broadcasting and broadband services. We are also going to examine reception and presentation on web browsers.

* MMT (MPEG Media Transport): A media transport protocol for media delivery in heterogeneous environments, which was standardized in MPEG in 2014.
 It is also specified as an element of the management and protocol layer of the ATSC 3.0, next generation terrestrial TV broadcasting standard under
 development in the U.S.
