Enhanced TV (ETV) is one example of enhanced STB application. There are two types of ‘applications’ which run in a STB (Set Top Box): Enhanced and Interactive. An Enhanced TV application(ETV) is the one which is based on ‘local interactivity’ and which does not require a return path back to the service provider. As an example of this type of application, consider a situation in which a broadcaster is transmitting pictures of a cricket match as a video data stream in parallel with another stream carrying supplemental but related material such as graphics containing player profiles, batting/bowling coverages etc. Using relatively simple technology it would be possible for a viewer to call up this extra information on demand either as an overlay or in a ‘window’. As for the viewer is concerned, this experience would be unique to the viewer, but it would involve no signal being sent back to the broadcaster to obtain the extra data.
As opposed to this an interactive application is based on ‘two way interactivity’. Here the viewer issues a request for extra information to the service provider, which travels along a return path and the service provider sends the requested data back either via the return path itself or ‘over the air’.What might be termed ‘low-level’ two way interactivity is demonstrated by a ‘pay per view’ service.On the other hand ‘high-level’ two-way interactivity is characterized by a continuing two-way exchange of data between the user and the service provider. A good example of this would be calling up a home shopping application via the TV screen.
It is used in particular in reference to Two-Screen Solutions TV + PC services. Generally users of these ETV services have their TV and computer in the same room, and navigate their web browser to a particular program-specific Web site that is synchronized to the live program by the broadcast TV network. Alternatively, some computers have TV tuner cards, or some TVs offer web browsers.
Notable "ETV" services are offered by the ABC, ESPN and Jacked.com for a number of popular programs such Monday Night Football, Sunday Night Football, The Academy Awards, etc. Similar services are offered for selected programs by other networks, pimarily using platforms operated by GoldPocket.
Enhanced TV is related to a more general, flexible, and ubiquitous two screen capability more broadly referred to as coactive TV, and also relates to the general behavior of "media multitasking."
