Seattle-based Widevine Technologies said today it has included Adobe's Flash format into its copy protection technology corral. That means Widevine can protect Flash-based video in addition to other formats.

Several years ago, Widevine made encryption software for video delivered over the Internet. It was a little too early to the game, however, and re-engineered its product for the more traditional cable and satellite operators. Now, it sounds like the market has caught up to Widevine's vision.

Widevine says its copy-protection system is used by video retailers and three television networks for delivering Internet video to PCs and other devices.
