Polling system as a mobile TV interactive application based on DVB and unicast hybrid network

This paper aims at proposing a polling system as a mobile TV interactive application that can be operated over DVB and unicast hybrid network. In general, polling system or polling model is a system where single server is designed to handle many request from clients and then decision must be taken by the server to granted i.e. the most number of request. In this work, we develop a new platform that combines digital television and unicast mobile cellular network transmission for polling system inside campus or office area. We first develop content server which can manipulate the DVB broadcasts and then the content is passed to the re-stream computer in which it connects the DVB and the Ethernet technology. This system is able to perform trans-coding work to customize the content so it can be received and played back on a smart phone. Designed DVB Server is able to broadcast content using the DVB modulator board DTA-110 and DTA-115. A re-stream computer using VLC application that is able to trans-code up to 3 channels are also successfully built. These servers can also provide interactive services in the form of polling.
