A new subscription TV service called Sezmi hopes to undercut Comcast in terms of price while integrating Internet programming with broadcast and cable. The Belmont startup has begun a test of its service in Los Angeles and is looking for people in the Bay Area to participate in a pilot here.

The Merc reports that Sezmi’s customers will get local broadcast channels via the public airwaves. But the company also relies on those airwaves, via deals with local broadcasters, to send pay-TV channels to its customers. It also plans to send on-demand and Internet programming to consumers via customers’ broadband connections.
