As car designers strive to present drivers and passengers infotainment systems that fully integrate consumers' digital lifestyle, it is important to use a multimedia networking backbone.

As car designers strive to present drivers and passengers infotainment systems that fully integrate consumers' digital lifestyle, it is important to use a multimedia networking backbone. The network should not only combine the long life cycle, reliability and tough environmental requirements of the automotive world, but it should also consider the rapidly changing interfaces of the consumer world.

Such a backbone must efficiently move A/V and other content around the vehicle while remaining cost-effective and highly reliable.

Media Oriented Systems Transport (MOST) is one standard for high-bandwidth networking used by many of the world's carmakers to implement this function. Through the auspices of the MOST Cooperation (MOSTCO), 16 carmakers have come together with 73 suppliers to develop this networking technology.

The first implementations came out of Europe, but now Toyota's Mark X ZiO, Hyundai's Genesis and Kia's Mohave models have introduced the technology into the Asian market. The early implementers have also expanded the use of this technology throughout their product portfolios.

CE connection
MOSTCO is currently working with the CE industry to make it easier to connect CE devices to cars. Efforts are also underway with the Consumer Electronics Association to bring the CE and automotive worlds together. Many OEM suppliers are also working on this front with their aftermarket divisions that can also benefit from using MOST.

MOSTCO has created an environment in which current implementers are jointly enhancing the standard. The "plumbing" needed to route A/V signals around the car is not a differentiator; by using a common standard, developers can take advantage of economies of scale and reduce development expenses.

Savings can be achieved by using a single interconnection to move all A/V and control information around the vehicle instead of having multiple analog wires to transport, for example, 5.1 surround sound, multiple video streams, and the required control data from the front to the back of the car.
