Abstract
As the transport scheme for Super Hi-Vision satellite broadcasting systems, which would be launched in 2018, it would be assumed that MMT (MPEG Media Transport), of which standardization has been finalized in MPEG, is adopted since it enables hybrid delivery using broadcasting and broadband networks. For realizing the broadcast services using MMT, required signaling information should be defined. In this report, we proposed a migration of signaling information based on the service information of the current digital broadcasting systems. Since the migration would not cover all the necessary information, we also proposed additional signaling information. In Super Hi-Vision satellite broadcasting, it is required that transmitting data files in addition to video and audio and providing same services as current digital broadcasting. So, we arranged the requirements for transport scheme and proposed MMT-based Application transmission scheme. In addition, we compared this scheme with other scheme and evaluated its performance by simulation. As a result, we found that the Media Processing Unit (MPU) mode of the MMT protocol is suitable for the requirements of application transmission and is able to transport files like data carousel transmission in current digital broadcasting. We also described that two management tables function as separate directory layouts for production and transmission and that the acquisition time is shortened by increasing the maximum size of the transport packets.
