Satellite, handheld wireless device specifications dominate DVB showing

Digital Video Broadcasting (DVB) highlighted recent success at this year’s National Association of Broadcasters convention in Las Vegas with two new landmark specifications, DVB-S2 for advanced satellite services and DVB-H for accessing DVB services on mobile handheld devices.

Building on the success of the DVB-S satellite transmission specification, DVB-S2 offers greater flexibility and better performance over existing satellites at reasonable cost. The new open specification offers a 30 percent capacity increase under the same transmission conditions, more robust reception for the same spectrum efficiency and will operate for carrier-to-noise ratios as low as -2dB to +16dB. Spectrum efficiencies up to 4.5 bit/sec/Hz can be achieved.

In addition, DVB-H is based on the current DVB-T standard and is purposed for the new service scenarios where small, pocket-size mobile terminals receive broadcast service on the move.

The new DVB-H standard, while by no way changing the current digital TV business models for fixed reception, could provide new business possibilities for a variety of players from broadcast and cellular operators to chip and equipment manufacturers.

For broadcasters, it provides a new vehicle to reach their customers while they are on the move. For cellular operators, it provides a cost-efficient way to implement data broadcast services. For users, the standard means a more inexpensive and richer content experience in the mobile environment.
