Internet protocol television will be one of the topics high on the agenda at the annual convention of the National Association of Broadcasters in Las Vegas, billed as the world’s largest electronic media show.

The keynote address for the opening of the NAB conference will be delivered by Ivan Seidenberg, chairman and chief executive of Verizon, which is aiming to deliver video services over its fibre optic telephone network.

In another conference keynote, the president of CNN in the United States will be speaking on IPTV: The Technology and Market Outlook. Jonathan Klein will discuss the impact and future of convergent media platforms in a session that will consider the opportunities and the potential pitfalls of adopting a multiplatform approach to content delivery.

Klein became president of CNN in the United States at the end of last year. Previously he was president and chief executive of The Feed Room, a broadband video company he founded in 1999.

A panel will then discuss how IPTV will enable operators to launch next generation services over existing infrastructure. Among the panel will be Jeff Weber, who is in charge of product and strategy for internet protocol operations at SBC, which is planning to roll out next generation video services as part of its Project Lightspeed initiative.

Later that afternoon, Lee Friedman, research director for IPTV services at BellSouth will discuss Interfaces, Middleware and Services for IPTV.

William Cooper of informitv will be speaking in the Broadcast Engineering Conference on Integrating Interactivity into Mainstream Broadcasting, discussing some of the issues involved in delivering successful interactive services and making the case that IPTV could finally deliver on the promise of interactive television.

The NAB conference and exhibition in Las Vegas runs from 16-21 April.
