Abstract
In this paper, we specify the realization of IPTV platform based on IMS. We provide an analysis of advantages and disadvantages of possible alternatives of providing IPTV over IMS. On the example, which is contained in the case study are on the hypothetical area shown differences between given alternatives.
Highlights
In area of efficiency is an important factor the amount of control messages required to support Access and control of IPTV services
IMS-based approach requires extra SIP messages to allow access and control of services, as well as management of protocols used for IPTV, where we include for example RTSP, IGMP or HTTP
In our proposed network architecture we reckon with backup line between Super Head End and regional levels, as well as the regional levels and local levels, which will serve to ensure the delivery of content in the event of failure of the primary link
Summary
In area of efficiency is an important factor the amount of control messages required to support Access and control of IPTV services (broadcast, Video on Demand, targeted advertising, Time-Shifting). Differences between IMS-based approach and IMS-integrated approach are visible in this area. IMS-based approach requires extra SIP messages to allow access and control of services, as well as management of protocols used for IPTV, where we include for example RTSP, IGMP or HTTP. IMS-integrated IPTV requires three to four times less messages for direct television broadcasting services. IMS-integrated IPTV requires three to four times less messages for direct television broadcasting services. [1]
