TiVo, the maker of popular digital video recorders, announced a partnership with YouTube that will deliver Web video directly to users' televisions.

With the YouTube deal, TiVo becomes the latest entrant into the marketplace for porting Internet video content to television. Apple introduced a new version of Apple TV with similar features in January. Although several companies are trying to merge the online viewing experience with the living-room big screen, no one product dominates the market yet.

The company's Series 3 and HD set-top boxes will support YouTube connectivity; earlier versions of the hardware did not support online video playback.

Sometime later this year — the company did not specify the date — a category for YouTube videos will be added to the TiVo interface. Users will be able to log into their accounts and gain access to playlists on the video sharing site directly from their televisions. The company also plans to enable users to subscribe to video feeds from across the Internet by using a software program called an R.S.S. reader.
