An UHDTV broadcasting system employing MPEG Media Transport (MMT) as its media transport protocol has been proposed for hybrid delivery of content. On the basis of this proposal, an MMT-based UHDTV broadcasting system has already been standardized and is being developed in Japan. This paper describes the structure of that system. The system supports hybrid delivery and has mechanisms to carry Universal Time Coordinated (UTC) information to eliminate clock drift between the sender and receiver. We evaluated the delay variation of UTC information through the use of a broadcast modulator/demodulator we developed and proved that it is small enough. We also conducted an experiment through an actual broadband network to confirm the functionality of hybrid delivery. The experimental results show that audio/video signals could be presented in synchronization with each other even though they are delivered separately over broadcast channels and broadband networks.

“…MMT serves to address the technical challenges of existing standards due to recent changes of multimedia delivery and consumption environments and new requirements from emerging use cases and application scenarios in the area of multimedia services. MMT is intended to overcome the current limitations of available standards for media streaming by providing a streaming format that is transport-and file-format-friendly, cross-layer optimized between the video and transport layers, error-resilient for MPEG streams, and convertible between transport mechanisms and content adaptation to different networks [4]. Especially, MMT is designed to support hybrid delivery using broadcast network and the Internet for multimedia services and to support the incorporation of companion devices for additional services.…”

In this paper, we propose a practical synchronization mechanism to achieve synchronized playback of the arrived 4K video bitstreams at different terminal devices based on MMT (MPEG Media Transport) protocol. In addition to the synchronized playback, we achieve the video playback with minimum service latency by estimating the accurate total end-to-end delay between the server and receiver. The conventional synchronization method between multiple clients generally calculates the time difference through communication between each client. Communication between multiple clients increases complexity and consumes network bandwidth. We do not rely on the communication between multiple clients but exploits the timestamp information supported by the MMT protocol.

“…Recently, users might want to consume multimedia services without being constrained by transport network. However, MPEG-2 TS packets have fixed length of 188 bytes, which is not appropriate for IP environments and is too small for configuring higher resolution contents such as UHD video sequences [7]- [9]. Therefore, ATSC is currently enacting ATSC 3.0 standard [10] as a next generation broadcasting system from February 2012.…”

Advanced Television Systems Committee (ATSC) produced ATSC 2.0 standard, which has been used for a HD/SD digital broadcasting service with MPEG-2 Transport Stream (TS) as a delivery protocol. Recently, users might want to consume multimedia services without being constrained by transport network. However, MPEG-2 TS is not suitable protocol for IP network. Thus, ATSC has enacted ATSC 3.0 standard, which is designed for a hybrid service through a conversion of both broadcasting and broadband channels. The ATSC 3.0 specifies delivery protocols as MPEG Media Transport (MMT) for a broadcasting environment and Dynamic Adaptive Streaming over HTTP (DASH) for a broadband. However, it seems difficult to combine broadcast and broadband for hybrid broadcasting, and it is difficult to synchronize media data between MMT and DASH. This paper suggests various new service scenarios to be brought up by a hybrid broadcasting, ATSC 3.0, and also proposes a stable mechanism for switching contents between different delivery protocols such as MMT and DASH.
