What capabilities are available for ETV applications?
ETV applications are typically bound to programming on cable networks allowing for interactive overlays that correspond to the video content. The capabilities of these applications include: * Graphic Overlays – Present on-screen widgets allowing subscribers to interact using their set-top remote control * Synchronized Delivery – Insert applications into programming (either pre-produced or live) to synchronize interactive overlays with the broadcast content * 2-way communication – Send form posts from the set-top box through the cable head-end to a response server via HTTP. This allows for applications such as voting/polling and advertising requests for information (RFI) * Telescoping to VOD – Interface with the video on demand layer to jump from linear programming to VOD assets * Dynamic Data – Use existing data feeds to update interactive applications with news, programming info, product info, polls, etc. * DVR Support – Set recordings for episodes or series on DVR boxes.
