MOST Cooperation specifies new remote control feature

The MOST(R) Cooperation (MOSTCO) – the standardization organization for the leading automotive multimedia network Media Oriented Systems Transport (MOST) – introduces the new “Remote Control” feature that is being added to the MOST specifications. The new feature allows the reduction of the number of microcontrollers and amount of memory in small and mid-size systems by obsoleting them in peripheral nodes such as displays and cameras, but also amplifiers and the like. Instead of having a microcontroller in each node, the other nodes can be controlled remotely by a central microcontroller – for example, the one in the head unit. Leaving out the other microcontrollers and memory can drive system cost down significantly. Performing all control centrally in the head unit also simplifies the development process considerably, as only one piece of software needs to be developed. Amplifiers and displays run without a local microcontroller and without local software.

“This kind of device architecture significantly lowers costs on the side of the remote devices and helps to optimize in the area of system partitioning, board space or even power dissipation in the remote device,” explained Rainer Klos, MOST Cooperation Administrator. “Typical examples for peripheral devices are cameras and rear seat entertainment devices including auxiliary I/Os, displays, etc.” At the MOST Forum, the new feature is shown in a demo that connects a head unit with several displays and an amplifier over MOST50 with unshielded twisted pair (UTP) copper wire as well as over MOST150 with coaxial cable. The whole system only has one microcontroller.

About MOST Technology
MOST (Media Oriented Systems Transport) is a multimedia networking technology optimized for use in cars and other applications. It enables the transport of high Quality of Service audio and video together with packet data and real-time control over a single transmission medium. MOST can use plastic optical fibers (POF), coax based electrical physical layer, and shielded and unshielded twisted pair (STP/UTP) copper wires that meet automotive environmental requirements. Today, MOST is used in over 140 car models as the communication backbone for their information and entertainment equipment.

About MOST Cooperation
The MOST Cooperation (MOSTCO) is the organization through which MOST Technology is standardized and refined so that it continues to stay abreast of the latest industry requirements. Today, it consists of 16 international carmakers and more than 60 key component suppliers. They have joined together to work with the MOST Technology and to contribute to its innovation. The MOST Cooperation is prepared to embrace efforts to further develop and standardize the technology for other industries and to establish the corresponding work structures. The MOST Cooperation was founded in 1998 to standardize MOST Technology as a global standard for multimedia networking. Audi, BMW, Daimler, HARMAN and Microchip Technology are its core partners and constitute its Steering Committee. For more information see
