Development of MMT Analyzer for ATSC 3.0 With the increasing volume of video streaming on the Internet, whether through ondemand or realtime services, the need arose for the development of transport mechanisms and protocols with greater flexibility and control of the quality of the transmitted service. To meet this new issue and ensure the evolution of broadcast television services, MPEG Media Transport (MMT), was developed to transport the hybrid delivery of multimedia streams in broadcast and broadband networks. This paper proposes the implementation of a specialized MMT Protocol (MMTP) analyzer for Advanced Television System Committee (ATSC) 3.0 developed in C language and integrated as a plugin for the OpenSource Wireshark software.

Proxybased approaches for IDCT acceleration In the boundary between wired and wireless worlds, proxybased processing has been recognized as an efficient approach to provide clientspecific adaptation to improve the overall performance. For the portable video decoding devices with wireless access ability, fast, lowpower decoding is desirable. In this paper, we propose a novel proxybased framework that is capable of accelerating the IDCT operations performed at the client. We introduce a proxyspecific IDCT algorithm that is not only suitable for the proxy framework, but has finegrained complexity scalability as well. We then demonstrate the effectiveness of the proxy by two examples. The first example is a simple proxy that is assigned the task of IDCT block classification, which is performed at the client along with the IDCT operation conventionally. Experimental results clearly show the complexity advantage of this method. The second example is a more active proxy. Adaptation to the image statistics is introduced. Simulations of the optimization process based on the average complexity criteria show that the client complexity can be further reduced, while maintaining a low side information overhead. Both examples provide the tradeoff between the clientproxy bandwidth increment and the IDCT complexity reduction at the client.
