Brief Description:

Digital Interactive Television (DiTV) is a system through which moving images and sound are broadcast and received, allowing interaction via the ?red button? on the TV remote control.

Description:

In contrast to traditional TV the information is compressed into computerised binary information which takes up far less bandwidth allowing more channels to be broadcast, and allowing interaction with viewers via the "red button" system.

Used For:

Digital TV is a useful method for ensuring that homes without internet access are able to interact with public information (e.g. health information) from their own living rooms. It is used by local authorities and hospitals to send and receive information from residents and patients:

NHS Direct currently runs a Digital TV service providing access to health information in the home.
Using the Sky version you can search for local services by entering your postcode using your remote control and you are presented with local service information.
Pilots of booking GP services through the television are currently underway.

Suitable participants:

People without internet access / people who are not able to attend public engagement events in person.

Cost:

High, unless the system is already set up and in use by the relevant body.

Time Requirements:

High, unless the system is already set up and in use by the relevant body.

When To Use / What It Can Deliver:

Digital TV is considered important as a way of reaching into homes without internet access.
The ability to create niche channels allows a more tailored and segmented approach to mass information provision.
People can select the information most relevant to them by choosing from a menu of options using the remote control.

When Not To Use / What It Cannot Deliver:

Digital TV is best used as a complement to other virtual public engagement activities.

Strengths:

Digital TV can reach people who do not have access to the internet or who are not computer literate. It is simple to use; users are guided through a number of different decision pathways using a familiar tool: the remote control.

Weaknesses:

Digital TV is slow compared to the Internet which may put people off accessing information through this method rather than via a website.

Actual participation in interactive services is currently fairly low, although more popular amongst younger age groups although we may see future increase in popularity.

People currently use their TV primarily for entertainment and not to seek information or interaction.
