Design and implementation of virtual class box 5.0 for distance learning in rural areas

Educational resources and transportation infrastructure scarcity has become the major obstructions for Indonesian education development. To solve these problems, Virtual Class Box (VCB) 5.0 device is designed as an effort to support digital distance learning. It provides videoconference to connect teachers and students from different school. This paper explains the design and implementation of a videoconference system, along with its supporting operating system, applications and hardware. The hardware includes CPU, filter, converter and peripheral user interface modules while the software is built based on Linux Ubuntu 14.04.3 LTS operating system, Linphone Voice-over-IP application, and other open-source packages. This videoconference system facilitates learning-multimedia-sharing with a simple user interface and can operate in internet bandwidth of under 2Mbps while generates delay propagation time less than 100ms. VCB 5.0 operating system provides a software that can automatically configure the designed application, as well as easing the usage of the application. The operating system also consumes minimum resource and can be recreated for mass production purpose easily. VCB 5.0 hardware made the whole system portable and compatible with various types of supporting hardware. VCB 5.0 device is also accompanied with manual book and usage video so it can be introduced widely to consumers.
