ABSTRACT

Personal Mobile Learning, a distance learning device. Designated to answer distance learning problem, start from teaching-learning problem, sometimes lecture in some condition, must absent in class, but the student need to earn the knowledge. Author indicated that time and place dimension sometime became barrier in educational world. So there’s opportunity in blue ocean area, to create a product which can be use to help teaching-learning process eventhough lecture and student in not in the same time & place. Thanks to fenomenal broadcast system innovation technology, DVB (Digital Video Broadcast), which can support personal broadcast methods to receive and transmit video, audio, image. User must only have a laptop and this set-up-box, no need a complete broadcast system product, so they can enjoy distance learning in their area. Personal Mobile Learning is a whole process in a product design. But the different is the methods, the starting point is not from the problem identification, but from the innovative technology finding then try to find idea in product apllication. Beside the design & technology, ergonomy and aesthetic still the main design consideration of this product. The image design are taken from keywords “simple-futuristic” style. The design process include sketch-rendering-modelling-prototyping.

Index Terms: product design, distance learning, DVB technology, personal boradcast, efficient, ergonomy, simple, laptop support

I. INTRODUCTION

Nowadays, one of the multimedia applications that have been enjoyed by the society is television. As the extent of media that utilize the satellite coverage area, the television becomes an effective means of unifying the region for the government. Government through TVRI deliver development programs and policies to all corners without geographic barriers that means. Since early 1990, Indonesia's television world changed in a revolutionary moment allowed to operate private television. Now, society increasingly has many show options that they can enjoy from morning till midnight.

Television in its development has now developed its function as a medium that provides educational content, this method is known as tele learning. Tele learning is one form of distance learning methods. An alternative method of this study is now in great demand by the public. Because of promising solutions to the problems of distance and time dimensions. This method is one of the methods of distance learning.

Time dimension that restrict human to enjoy the television programs, with the background of their mobility difficulties

Activity

There’s no television broadcasting technology-based on digital technology TcchnologyExisting streaming video is quite time consuming Operational Requires a tool that combines the ability of Television and Personal Computer TechnologyIndonesian society prevailing socio culture challenge. Two prominent conditions, namely that urban communities tend to be mobile, and sub-urban communities who still adhere to conventional customs.

n

Existing Tele-learning methods, from the complexity of equipment needed, limiting the mobility of people.

Activity

Teachers with students meetings which are not practical (must be met in the same place and time)

Ergonomy

Not open edutainment, teaching and learning process can only be enjoyed by participants

Procedure

Environmental and educational methods that require more expensive funding Price

II. FUNDAMENTAL THEORY

Distance learning1 is defined as a system of education whereby students officially attended courses at school or college but receive instruction in some remote place. Traditionally, the correspondence has become mainstream media. But now the main delivery systems most widely used is through video, audio and computer technology

Tele kearning2 is an educational activity, with teachers and learners who are geographically separate, because it is based on electronic and communication devices using the TV as the receiving equipment. Actually the concept of tele education arises because driven by several factors:

1. Fostering an environment and educational methods that require relatively little funding.

2. Open resources (material, knowledge, human) that can better be used by many people (resource sharing)

3. Provide an alternative meeting between teachers with students more easily (not limited to the place and time allocation more easily adjusted).

4.Minimize administrative and managerial problems, which are often found in educational institutions in general, such as problem learners quantity, payment problems, issues assignments for students, the problem of absenteeism.

5. Can give an more broadly services (not limited to classrooms), as in the discussion of the industrial world can show an industrial area which will be discussed in class.

DVB3, short for Digital Video Broadcasting, is a suite of internationally accepted, open standards for digital television maintained by the DVB Project, an industry consortium with more than 300 members, and published by a Joint Technical Committee (JTC) of European Telecommunications Standards Institute

(ETSI), European Committee for Electrotechnical Standardization (CENELEC) and European Broadcasting Union (EBU). The standards can be obtained for free at the ETSI website after registration.

DVB Goes Worldwide4 : By 1997 the development of the DVB Project had successfully followed the initial plans, and the project had entered its next phase, promoting its open standards globally, and making digital television a reality. DVB standards were adopted worldwide and became the benchmark for digital television worldwide.The DVB Project expanded into new areas when it took over the activities of the Multimedia Home Platform (MHP) Launching Group. This resulted in the release of the first DVB-MHP specification in June 2000In May 2001 a new commercial and technical strategy for DVB was adopted - known as DVB2.0 – encompassing the vision is to build a content environment that combines the stability and interoperability of the world of broadcast with the vigour, innovation and multiplicity of services of the world of the Internet.Finally 2003 brought the 10th anniversary of the DVB Project and a chance to look back with pride on a decade of cooperation the success of which is plain to see around the world. 

III. METHODS

The research method is qualitative method, how to obtain the data used in the writing of this report are: Direct observation, ie, data collection techniques by carrying out direct observations Study literature, ie, approaches that support the literature as reference in problem solving Field study; the technique in the field interviews conducted by or interviews with resource persons and the

community which in this case knowing the subject matter of the topics have been selected Field notes and documentation; the technique by way of recording all data in the field and the results of

interviews and documents the expected things or issues related to research.
