An Efficient Transmission Scheme of MPEG2-TS over RTP for a Hybrid DMB System

Abstract

Hybrid digital multimedia broadcasting (DMB) is a next-generation mobile TV system that combines broadcasting and wireless communication networks and can provide various high-quality multimedia services. However, if a system adheres to the current standard of transmitting the DMB content in the form of MPEG2-TS through wireless networks, it results in a burden on the network due to low transmission efficiency. The reasons for the low transmission efficiency are as follows. First, due to its constant bitrate characteristic, DMB MPEG2-TS includes a considerable amount of needless information, such as NULL packets and stuffing bytes. Second, due to the inflexibility of the Real-time Transport Protocol (RTP) standard, one cannot fully utilize the maximum transmission unit of the network when converting MPEG2-TS to RTP stream for transmission. This paper proposes a new transmission scheme that resolves these problems. Experiment results show that the proposed scheme improves data bitrate transmission efficiency by 8% to 36%, compared to the standard scheme, in the streaming of various real-DMB contents.

SVCEval-RA: an evaluation framework for adaptive scalable video streaming

“…The methods for video streaming covers a wide range of technologies: from simple progressive download, where a single video file is downloaded over HTTP and played back at the same time, to real time streaming techniques using packet-based delivery, for instance with the Real-time Transport Protocol (RTP) [32,33]. However, these traditional video transmission schemes lack of the necessary flexibility and adaptability since the video file is delivered to the enduser with a constant bit rate through a persistent source-destination connection.…”
