More and more coaches are equipped with video monitors to provide entertainment and information. Such bus entertainment systems require a powerful and reliable control panel. On behalf of a a large bus manufacturer, DResearch has developed such a unit, the MUMBOX. It is factory-installed in coaches as a standard feature.
This box allows the driver to play media streams (audio and video) on the individual screens. The MUMBOX switches different video and audio inputs to different video and audio outputs. It is controlled via CAN bus commands. The software runs on an Atmel microcontroller and is written in Embedded C. The video chip used in the MUMBOX allows the fading in of text and symbols in the video.
DResearch vehicle electronics has developed both the hardware and software of MUMBOX in cooperation with DResearch Digital Media Systems and also launched its production and distribution.
