We got a hold of the Yahoo! TV Widget SDK earlier this week (WDK)! Exiting stuff. As I mentioned previously, we are working with a handful of clients on developing Yahoo! TV Widgets for them so this is the final step in that process. 

The WDK runs on Debian or Ubuntu Linux (so if you don’t have one of these your need to get VMware). The WDK allows developers to develop widgets for the Yahoo! Connected TV platform based using JavaScript and XML. The widgets, however, rely on the media player and APIs resident on each consumer electronic device for video playback so it appears media player capabilities may vary.

On your Connect TV, your widgets live as a list of snippers at the bottom of your TV screen that can be accessed through your remote control.  The widgets are actually very similar in design (tab based) to our widgetmatic 600 series..which will make porting them even easier!

Will keep you updated!
