Abstract:
MPEG Media Transport (MMT) is a new international standard aiming at addressing the emerging multimedia services over heterogeneous packet-switched networks including Internet and broadcasting networks. Due to the heterogeneous characteristics of the broadcast and broadband networks, MMT provides an efficient delivery timing model to provide inter-network synchronization, measure various kinds of transmission delays and jitter caused by the transmission delay, and re-adjust timing relationship between the MMT packets to assure synchronized playback. Exploiting the delivery timing model, it is possible to accurately estimate round-trip time (RTT) experienced during MMT packet transmission. Based on the measured RTT, we propose an efficient delay constrained ARQ (Automatic Repeat reQuest) scheme which is applicable to MMT protocol based real-time video communication over IP networks.
