eTV - Abstract

Enhanced television is a type of interactive television service provided through analog or digital transmission. Users can experience varying levels of interactivity through single-screen and dual-screen applications. Through enhanced programming, users can select icons on the screen or press buttons on their remotes to display additional information, visit web sites, play games, or to order products. Return channels must be used in order to send user responses to the appropriate destinations. To receive enhanced television, a basic system with certain components must be in place. Set top boxes are the primary devices used to decode enhanced TV broadcasts and allow users to interact with the content. PCs with special tuner cards can provide the same functionality.

Broadcasters, and content creators are uniquely impacted by the rise of enhanced television. The tools and methods used to produce and deliver television programming are being updated to incorporate a means to embed enhanced content into the signal. Advertising, the historic means of generating revenue for broadcasters is just one component in a new business model that includes pay-per-use, subscription fees and T-commerce.
