Offering video services over existing IP networks holds considerable promise in terms of new revenue and business growth opportunities for video service providers. Home video in all of its forms is now a large and growing business, and Video on Demand (VoD), networked Personal Video Recorders (nPVR), and interactive video services can offer considerable convenience and tailored services in an already strong market. Early indications are that a large percentage of broadband customers would subscribe to interactive video services, with considerable potential for growth. This promise is offset by the challenges of designing and deploying scalable, reliable, and cost-effective infrastructure for television services over IP networks (IPTV).
