In the Wednesday Keynote Joost CTO Dirk-Willem van Gulik explained a bit about their service. Joost mostly behaves like normal TV. You can “channel up, channel down; volume up, volume down” (as described by a well known Cable Exec.) We can look at the screen to get an overall view of the service. The EPG on the left shows a fairly standard line-up which includes My Channels. However you can watch shows like a TV as well scrub back and forth like a PVR. Also since there are content objects you can tune into at any time it also behaves like VOD. The area at the top displays the content owner’s information and what’s really interesting is that after you click and an overlay comes up the resulting overlay is writable by anyone. Anyone can write, can interact with content or just display it as an overly to sit on top of the content. What this means to content owners I think is still up for debate. One of the issues they have been struggling with is one which is familiar to all of us-How do you find content? The list just keeps gets longer and longer as more content is added to the network. This is something which they will be spending significant resources on over the next few months as they gear up for a major release in the summer timeframe. The bottom has a search box anyone can expose on their own site. Every piece of content has own URL and users can comment on parts of the video. You can save a list as a channel (“Smart Channel”), which you can share with friends. On the right there is displayed MyJoost where when you click, you see an overlay of widgets on top of video. Once again there are APIs for this and you can pin the widgets to the screen. There are almost limitless applications that can interact with viewers and content.
