We’ve received a couple of anonymous tips that DirectTV, a $24 billion satellite TV provider, may be entering the online TV wars with a new site called DirectTV Web On Demand. The site would compete with startups like Hulu, Joost, Fancast, Sling.com, etc.

We don’t know much about the service, or even if it’s real. One of the tipsters says they’ve worked on the project and supplied us with the mockup screen shot above, which could quite possibly be real. On the other hand, we’ve spoken with industry insiders and they say they’ve heard nothing about the project.

The screen shot shows Heroes, which is an NBC show. The only way for Fox and NBC shows to be syndicated on the web is via a deal with Hulu. For CBS shows, they have to go through the CBS Audience Network.

That means it’s either very, very early in the development process or it doesn’t exist at all. We have an email in to DirectTV for comment.
