With the unveiling of the SiriusConnect SC-V1 Audio/Video Tuner, the question remains about the service that feeds the video content to this system - current entitled Sirius Backseat TV.

According to sources, Sirius Backseat TV will be offered for approximately $6.99/month. This is a separate subscription from the regular Sirius Satellite Radio subscription.

These sources also claim that three channels will be made available for the service - all targeting children. While no details on the source of the content, Sirius was showing Cartoon Network programming at CES. So here's a bit of history on Cartoon Network, and the likely possibilities for channel content, should a deal with Cartoon Network actually be real:

In September of 2006, Cartoon Network launched Cartoon Network Video - and online video service that is currently only available in the U.S. In July of 2006, Cartoon Network and VIZ Media launched Toonami Jetstream which provides online streaming video of Cartoon Network content. Toonami is also the brand owned by Turner Broadcasting (who owns Cartoon Network) for an action-oriented animation channel in the UK. Turner also owns Boomerang, which is a subset of Cartoon Network (and is a popular channel overseas - especially in the UK where it beats out BBC Kids).

Again this is all speculative, so a grain of salt may be appropriate at this time.
