Abstract

To face on the growing needs of the campus network resources, TV broadcast system based on campus network has become a simple and effective solution to video resources service over campus for its stability and diversity. With the promotion of campus network performance, application of HD video stream over the campus network has emerged. The characteristics of the multicast technology make the transmission of HD video stream become possible on the campus network. This paper mainly discusses the signal source, the production of HD stream, multicast technology and user terminal etc., and tries to build a feasible campus network HDTV broadcast system. The experience can be used as reference to the construction of an HDTV broadcast system over campus network. [ABSTRACT FROM AUTHOR]

Abstract

The massive upsurge in production and demand of crowdsourced live streaming necessitates feasible and cost effective solutions in future cellular networks. Video multicast is one of the viable options to deliver live video using standardized multicast technologies, such as evolved Multimedia Broadcast Multicast Services (eMBMS) architecture. However, eMBMS being a service-oriented architecture, it does not support crowdsourced live video streaming from popular providers like Twitch, YouTube Live, and Facebook Live, where millions of viewers watch live streams. This article explores the possibilities for the crowdsourced service-less video multicast in fifth generation (5G) Radio Access Network (RAN). We highlight major limitations in the standard eMBMS architecture and propose a viable solution using Network Function Virtualization (NFV) and Mobile Edge Computing (MEC). The main challenges related to the initiation of an eMBMS service are presented, followed by our proposed network architecture, which augments the eMBMS architecture to initiate a service-less multicast video delivery for crowdsourced live videos. We evaluate and validate the proposed architecture using a real-world live video dataset. Our results depict the feasibility of the proposed architecture to multicast crowdsourced live streams and significant savings in cost and network consumption. 1986-2012 IEEE.
