Sezmi is a startup targeting high def and on demand content at a very reasonable price point. Broadcasts over the air, then works sort of like a digital recorder.
This service will be VERY COOL. Some company called Harris is working with them to set this all up.

Sezmi, a set-top box provider which aims to provide content from both broadcast networks and the Internet to consumers, has wrapped up technical trials and is preparing for a consumer rollout early in 2009.
The company has completed its "first milestone," David Allred, senior vice president of marketing and product management at Sezmi. The company has successfully tested its service with Fisher Communications and Tribune Broadcasting in Seattle, and begun broadcasting through a partnership with Harris in Melbourne, Florida.
