the information contained in the application in accordance with the
conditions that currently occur.
CHAP VI RESULTS
In general, digital TV broadcasting is not too different from the analog TV broadcasting. Only, in
the broadcasting digital TV signals sent by pemancara not broadcast but was in the form of
digital data that has been processed previously. This is possible because in some of the analog TV
stations already use digital devices in the production process in the studio source release.
Initially the results are still shaped analog broadcasts will be digital undergo a process of
change by using a DAC Digital-to-Analog- Converter to be broadcast. With conditions like
this, analog TV stations are already doing in the studio digitization process will be easier to
immigrate.
Picture 4.1. Illustrations in the DAC One of the advantages of digital TV
broadcasting is there an application that can run between the digital data broadcast called MHP
middleware. With the middleware will enable an application running on a digital TV broadcasting so
that digital TV can be interactive TVs that connect producers and consumers indirectly.
To design the application in general easy to understand and to devise solutions to problems that
have been found. The design of the transition diagram using two different diagrams of Data Flow
Diagrams DFD as tools and as process flowchart
Stages of Development of the Waterfall
1. Analysis
At this stage of analysis the authors find the data and information according to the
needs of the application is also designing the concept of the application and look for
software that is compatible with making the application.
To create an T-Commerce application with Return Channel workmanship performed
by the same two stages of file creation. NKR for T-Commerce and Return Channel and
making a server for the Return Channel Designing applications for digital TV
using the two software is iCareus and NetBeans.
On the concept of the menu on the application used the concept of a scene that is
the turn of the menu display content according to the selected menu. In addition to the
concept of a scene menu there is also the concept of a sub-menu menu, only if using
this concept will make the application look untidy.
2. Design
Once the needs analysis is complete the next step can be executed is the design phase.
Stage design Design is making an application specification, the specification that
will be created with the following stages:
1.The design uses state transition diagrams 2. The design of the prototype
3. The design of the interface interface
3. Coding and Implementation
Designing for the return channel of MHP can be done once completed. Creating a
software return channel is required in accordance with the contents of coding to be
used on the return channel. Make the return channel only requires 2 software that is
NetBeans and Java. There are several things that must be considered in the use of such
software is
• NetBeans used to be versu 6.7.1 or more. This because there are several components
in NetBeans 6.7.1 needed to manufacture the return channel. This component is
absent in NetBeans with a lower version. One is called JavaServer Faces
frameworks
• For Java, there are 2 two types used JDK is JDK 1.4. and JDK 1.6. Each JDK has a
function each to run several different visual library.
• Visual Library run in accordance with the required program and on the run with the
corresponding JDK. If one library or the JDK does not work then the project will
not be able to run properly.
4. Testing
Testing method used is a black box method. Because the application is run and
tested whether it meets user needs. To test this application, it takes at least 2 two pieces of
computer or laptop. The first computer will connect to your PC to broadcast transmitters
can be accepted by the settop-box. Later the other computers will be used as a server
connected to the settop-box

CHAP V CONCLUSIONS RECOMMENDATIONS
5.1. Conclusion
After doing some research and try to make t-commerce applications, then the author
can conclude that 1.
T-Commerce applications as one of the applications running on Digital TV,
can still continue to be developed considering the number of TV users in
Indonesia.
2. Making E-Commerce application with
Return Channel can be made by looking at the needs of existing users,
so that the contents of the application can be replaced in accordance with the
wishes of the user so that interactions can occur when the application is in
implemntasikan. 3. Function libarary on Return Channel
plays an important role because if you use a library that does not suit your
needs then the server will not be able to run and process of interaction goes
only one direction one-way only
5.2. Suggestion
After conducting research through seminars and presentations authors get
different advice from those who have seen the design of this application, one of
which is
1. In making the research methodology
waterfall should be poured in techniques and tools that are used for
scientific matters and a deeper analysis.
