Comcast will launch Gemstar-TV Guide’s broadband TV guide on Comcast’s portal site. The online guide allows subscribers to search for online video content from 55 broadcast, cable network and other major entertainment-focused Web sites, as well as from “professional grade” user generated videos. Gemstar says they have indexed over 110K user generated content clips. Each distribution partner, which in addition to Comcast includes YouTube, AOL Video, Yahoo, Brightcove, and others, creates a customized broadbandTV portal, powered by Gemstar-TV Guide’s technology.
