Access

Digital and Interactive Television is accessible in which most types and levels of the

learners could access the digital and interactive television. Moreover, Digital and

Interactive Television is very flexible in which the target group could use it and

benefit from its capabilities and it fits most kinds of the learners.

Costs:

In the past, it is called interactive TV because the consumers had no options to

subscribe in some channels and no options to save some clips in TV by USB so, it

wasn’t very expensive. However, now, it is called Digital and Interactive TV because

it has various options in digital to make use of the implementations of latest

technology such as subscription or using USB therefore, it is very expensive. In

addition, it depends on the size of classroom and number of students to determine if

learners need one TV each one or one TV for a group of students. One more thing, if

this technology costs a lot, there should be appropriate alternatives such as using

some offered DE technologies like Windows Live Meeting.

Teaching and Learning

It requires auditory and visual learning and they fit Distance Learning.

Furthermore, television has replaced its technology from analog to digital leading to

a digital-interactive.

The best technologies for supporting teaching and learning in this environment are

Broadcasting, internet, microphone, and cameras. What’s more, content could be

integrated in DIT. This technology develops the skills of constructing and arranging

the production and distribution of information efficiently.

Interactivity and User-friendliness:

It enhances synchronous interaction and asynchronous interaction because it could

be alive and replay. Also, it is easy to use and learn DIT because it fits most of the

educational levels.

Organizational Issues:

Organization and Institution requires Photographs, 2 D or 3 D graphics, animations

with audio visual stimulators and satellites to provide stability and support. The

barriers to using this technology successfully within the institution are Lack of the

instructional equipment and weakness of Infrastructure. Moreover, Organization

must renew the devices and follow the latest innovations in broadcasting to come up

with the development of digital-interactive television.

Novelty:

Naturally, the new in this technology is that there are improving data processing

rates; the capacities of computers, plus software have distinguished DIT appearance

into every aspect of life as well as in broadcasting. Its technical capabilities are

Better quality audio and video broadcast, more channels and higher capacity,

capability to correct data errors which may happen during broadcast, decrease in

generation loss due to data copying, compatible and cooperative with other

transmitting environments like the Internet, easy access to audio and video data,

editing and archiving, and provision of mutual data transfer or briefly interactivity.

Speed:

The content of the courses could be combined to DIT quickly and it distributes the

courses in short period by utilizing the capabilities of DIT. Actually, materials could

be modified anytime because DIT enables the users to save the editing files so, the

content could be changed quickly.
