T “Triple play” is a hot buzz phrase in the communications industry and is quickly becoming part of our common vocabulary. The triple play is a bundled offering of voice, data and video carried on a common infrastructure. Speciﬁcally, such systems carry voice over Internet Protocol (VoIP), broadband data and video over IP or IP television (IPTV). Because IPTV, in particular, brings extra complexity to the mix, it is shaking up the communications industry in terms of both technology and economics. Triple-play services, including broadcast TV, video-on-demand (VoD), VoIP, gaming and data, represent serious challenges in the industry. As one example, IPTV is new to many people and the task of characterizing IPTV quality of service (QoS) is difﬁcult and complex. It will become easier once a standard for measuring IPTV quality emerges from the numerous proposals currently under consideration. Within the industry, service providers are racing to develop and deploy robust IPTV services before their competitors acquire signiﬁcant market share. As a result, equipment manufacturers are quickly developing products and are seeking to standardize them among service providers. Exploring the elements of complexity With IPTV speciﬁcally and triple play in general, the inherent level of complexity becomes evident when services must be deployed quickly and with video quality comparable to cable or satellite. The scope of this complexity includes market and technology issues: • The global market for integrated consumer devices that deliver triple-play services is growing explosively and there is always a new device that needs to be compatible with the others. • The prime concern is maintaining combined high QoS for voice, data and video when transmitted over the same infrastructure. IPTV broadcast requires high bandwidth with near real-time service. VoIP is not bandwidth intensive but is very sensitive to delays and packet loss. • Good quality of experience (QoE) has become imperative because revenue and proﬁts depend on positive perceptions of each new service. • IPTV and VoIP represent a highly distributed signaling architecture with a large number of signaling protocols (e.g., IGMP, RTSP and SIP). • IPTV and triple play must support new and advanced services such as VoD and click-per-view advertising.
