MMT: An Emerging MPEG Standard for Multimedia Delivery over the Internet

摘要

There is no doubt that multimedia services over the Internet will be continuously and dramatically increased and transport-layer protocols of the various networks will converge to IP regardless of their characteristics. However, the current Internet architecture is not optimal for multimedia services, and current solutions for multimedia delivery over IP are not particularly efficient. Therefore, future networks, such as content-centric networks (CCNs), will not only provide a better network architecture for multimedia delivery, but will also require a multimedia transport solution that is better aware of requirements of the delivery network. MPEG Media Transport (MMT) will address such requirements, both by exposing the detailed information required by the underlying delivery layer that is agnostic to the specific media type and by defining an application layer protocol that is optimized for multimedia delivery. MMT is currently under development in MPEG and is expected to be published as an international standard in 2014.
