Interactive IMS-based IPTV plunge into the reality game show

Abstract

Convergence of fixed, mobile and cable networks has tackled well known patterns where incumbent operators have reliable understanding of telecommunication and broadcaster of TV provisioning. Currently both parties are cannibalizing their business models by providing integrated bundled solutions: telecommunication, Internet and TV - known under the notion of Triple Play. To-date, a lot of vendor specific silo approaches are appearing. These approaches lack of three characteristics: cross-vendor interoperability, integrated telecommunication and interactivity. Thus, Standard Development Organizations address the standardization of open interfaces to address these issues. This paper proposes a novel IPTV architecture addressing interoperability, telecommunication and interactivity by designing an integrated IMS-based IPTV solution that fixes personalized and interactive services and their coherent integration. Ericsson's vision of an IMS-based reality game show serves as one evaluation example

A signaling architecture for multimedia MBS over WiMAX

“…Extensions to IMS session setup for supporting multicast-based many-to-many services are discussed in [21]. Proposals in [22,23] enhance the IMS-based service architecture illustrated in [19], by adding scenarios aiming to a future interactive TV experience, illustrated by a SIP signaling exchange.…”

“…The SIP-based IMS architecture is the most largely used in the IPTV signaling proposals [18,19,[21][22][23][24]. Nevertheless, IMS is a very complex reference architecture, and its complexity often leads service providers to resort to simplified architectures, often proprietary, to provide users with advanced services.…”

“…As already mentioned in Section 2, in the IMS-based architectures the use of the SIP INVITE message is mandatory to create a session state and to provide an IPTV service [18,19,22,23]. Even other proposals [21] try to extend the IMS session setup for multipoint-to-multipoint service type, using again INVITE messages.…”
