MMT, new alternative to MPEG-2 TS and RTP

During the last two decades MPEG has successfully developed the standards for multimedia delivery such as MPEG-2 TS and ISO Base Media File Format. Recent changes of multimedia delivery environment due to the rapid increase of multimedia services over the Internet brought new requirements to the standards for multimedia delivery, namely (i) flexible and dynamic access to multimedia components, (ii) Easy conversion between the format for storage and the format for the packetized delivery and (iii) mixed use of multimedia components from multiple sources including the caches and the local storages. MPEG has started the development of MPEG Media Transport (MMT) standard to respond to such new requirements. In this paper, challenges to MPEG-2 TS and RTP regarding new requirements are discussed and brief descriptions about MMT showing how MMT provides solutions to those challenges are provided.
