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

This is the clasroom situation when distance learning was adopted, lecturer and student are not in the same place. But they still can communicate using distance learning technology applied, nowadays there are many kind of technology support this activity: IPTV, teleconference, etc. but it still had some problem and difficulties
DVB, 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.

The standards can be obtained for free at the ETSI website after registration. DVB allows the delivery of virtually any kind of digital form into the house. Although it is the High Definition TV, multiple channel standard definition TV (PAL, NTS, or SECAM) or new broadband multimedia and interactive facilities., DVB deliver the owner to use the MPEG-2 packets as "data storage", and DVB and information facilities identify the packages.
Nowadays, there are 3 main technology supported distance learning There are video teleconference, instructional TV, and DVB-H RCT For Vid,tele the user cant have full 2 way communication And also the same in intructional TV, but in instructional TV the receiver can receive not only video & audio, but also some image, document,etc And the DVB-H RCT can do all both activity the interactivity and file sharing
Of all of these requirements, the hardware features have almost all laptops have that need, but there is not yet owned and it is the primary features hardware needs to be created, namely DVB-RCT card, built-in video camera, a speakerphone with PCMCIA interface ports. Here is the full data Dari semua kebutuhan tersebut, hardware features laptop telah nyaris memiliki kesemua kebutuhan itu, namun ada yang belum dimiliki dan itu adalah kebutuhan hardware features primer yang ingin diciptakan, yaitu DVB-RCT card, built in video camera, speakerphone dengan interface PCMCIA port. Berikut ini data lengkapnya
Suporting tools can be interpreted as excluding devices designed products, these devices during operation will support the operations function product of this distance learning tool. In this case, the tool has a significant role, the tool is a laptop / notebook. Laptops serves as host of products to be designed. Because later in the operating system, distance learning facilities will serve as the compatibility of a laptop. Simply put this tool used in conjunction with the use of laptops. Laptop plays an important role, because in accordance with basic principles of development of distance learning facilities, namely the personal mobile, the laptop that is also principled mobile, is the right solution using the tools
Viewing and analysis of data collected, then this aspect is more likely to close when grouped within the boundaries of design. Given the data summarized absolute properties to be fulfilled. From this data could be concluded that the resulting product specifications. It would appear that a measure of the product later. Melihat data dan analisa yang berhasil dikumpulkan, maka aspek ini lebih cenderung dekat apabila dikelompokkan dalam batasan desain. Mengingat data yang terangkum memiliki sifat mutlak untuk dipenuhi. Dari data ini bisa disimpulkan spesifikasi produk yang dihasilkan. Akan muncul sebuah ukuran dari produk itu nantinya.
Tingkat kepresisian, produk ini berdimensi kecil dan ringan, sehingga ketepatan pengukuran dalam desain dan proses manufaktur penting, dengan batas toleransi 0,01 mm Teknologi DVB-RCT masih dalam status penelitian, belum di launch dan dipasarkan secara umum. Sehingga masyarakat c alon pengguna pasti akan meraba fungsi, teknologi, operasional produk ini. Bahkan mungkin butuh waktu penetrasi awareness kepada masyarakat Prediksi produk masa depan dengan kandungan high tech , membutuhkan hitungan product-technology trend yang cermat, dan asumsi-asumsi yang tepat, tentang peluang produk ini ditengah inovasi teknologi yang lain
