Digital and interactive television provides accessible, cost-effective distance education. It allows for both synchronous and asynchronous interaction. While initially expensive due to subscription and hardware costs, it can be used flexibly by different learner groups. The technology enhances teaching and learning through audiovisual content integration and skill development. Organizations need equipment like cameras and satellites to support digital interactive television broadcasting and overcome infrastructure weaknesses. The technology's novelty lies in improved data processing, computer capabilities, and software that enable better quality audio/video, more channels, error correction, and interactivity. Content can be combined and distributed via digital interactive television quickly due to its editing and archiving abilities.

Access
Digital and Interactive Television is accessible in which most types and levels of the
learners could access the digital and interactive television. 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
Cost
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. In addition,

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(play bace). 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

content could be changed quickly
