Dish Network announced an upgrade for its entire ad insertion systems – supplied by SeaChange International. Separately, Dish said it completed its migration to a new conditional access technology supplied by Nagravision.

Dish said it’s upgrading its spot advertising insertion systems to meet the growing demand for high-definition ad placements across its North American footprint . The upgrade of its multichannel advertising delivery platform will include the introduction of the SeaChange Spot 5.0 ad insertion system to support more than 600 channels of commercial delivery.

“Not only do we want to give our advertisers the ability to place high-definition ads on our HD channels, but also we want to provide our subscribers with an end-to-end HD viewing experience that does not drop off during commercial breaks,” said Michael Kelly, executive vice president of direct, commercial and advertising sales for Dish Network.

Dish has gone exclusively with SeaChange since it launched.

Dish has also had a long relationship with Nagravision, through its parent EchoStar. EchoStar and Nagravision have had a joint venture called NagraStar that was founded in 1997, shortly after Dish was.

Dish said it signed a 10-year contract extension with Nagravision and NagraStar for CA technology. Having signed the agreement, Dish apparently felt it safe to mention that in December, it completed a migration of its more than 14 million subscribers to Nagravision's new generation of security technology.

"Nagravision's flexible solutions – in supporting new services, features and functionalities, as well as their pragmatic approach – have helped us grow our pay-TV business in an innovative way," said Charlie Ergen, chairman, CEO and president of Dish Network.
