Pioneer SyncTV was introduced in private beta today. The service is not one of the first of its kind but there are a some features that make SyncTV better than competitors like Amazon, Apple, and NBC.

One excellent feature is it is compatible with Mac, Linux, and PCs. Users can specify up to 5 computers for playing back videos. And once compatible portable media players are released, users will be able to watch videos on up to 10 different devices.

The service uses subscription, users will pay $2-$4 per channel. A few channels will make their content available on a pay per download. Most of the time users will only have to pay the monthly fee to get unlimited downloads of TV programs.

Like with every new online TV service there is a lack of content. The known channel is Showtime. SyncTV does look promising.
