Nex Tv 2009 Hybrid Networks Verimatrix 111809

The strong movement towards “content anywhere anytime” and “prime time on my time” puts an increasing pressure on operators to keep customers happy. Pay-TV operators recognize that they must offer advanced services such as HD and video-on-demand. However, network bandwidth limitations often present a challenge. Moreover, the lack of a return channel in broadcast networks means that interactive applications are limited.
One solution combines DVB and IP delivery technologies through a hybrid network approach that takes advantage of the strengths of each: an RF-based broadcast network for one-to-many linear content delivery, combined with an IP network for interactive one-to-one services such as video-on-demand (VOD) and shopping. With a hybrid approach, the opportunity exists to offer new of subscriber benefits in a seamless experience while the service operator improves both competitive position and revenue potential.
Operators can take different paths in the transition to a higher-value subscriber base, depending on their current infrastructure and business objectives. For example, DVB broadcasters may add IP-based video-on-demand services, while IPTV operators can benefit by adding DVB satellite or terrestrial channel bundles.
Content security technology has followed the evolution of pay-TV networks. While analog systems never had strong content security, the introduction of digital video broadcasting in the mid ‘90s had a profound impact. This led to the development of so-called conditional access systems, which in design have remained quite constant since then. Since broadcast networks were all one-way, a strong security element was required in the set-top box. The technology chosen was based on smart cards.
With the introduction of IP-based video in two-way broadband networks, a radical change took place. Instead of smart card based security, companies like Verimatrix developed a new architecture based on two-way communication and software-based security. By using technology proven in e-commerce applications, it was possible to improve the security for IPTV to such a degree that smart cards were no longer required.
Since a hybrid network is in principle a two-way IP network with a broadcast overlay, IPTV content security can be directly applied. This offers an opportunity to transition from legacy CA systems, based on smart cards, to a single software-based system that supports both broadcast and IP
