Most-Solutions of Automotive Fiber Optic Audio and Video Systems

Recently automotive sensors become more intelligent, transmission and processing of data and control signals between the various sensors of the car, the the automotive bus program selection is extremely important.


In the field of vehicle, in-car entertainment systems escalating development, audio video, telematics and navigation-based applications, car manufacturers continue to introduce more complex automotive audio and video products, in order to establish an efficient network between these devices. connection to integration and transmission of sound or images, software packages, control models, equipped with more high-performance micro-controller and with the complexity of the control software.

 

Early LIN Bus (20kbps), CAN Bus (1Mbps), the FlexRay (10Mbps), Bluetooth 2.0 (3Mbps) poor transmission rate performance, being in the transmission rate stability, anti-interference performance the a higher superiority and applicability MOST multimedia bus protocol replaced.

 

MOST (Media Oriented System Transport) referred media directional transmission system. Car MOST AV system using optical fiber as information transmission media, digital signal transmission. These products provide low overhead and low-cost interface for simple equipment such as the microphone and speaker. MOST can make more intelligent equipment and vehicle network equipment to automatically match function, and the establishment of a sophisticated control system for the driver to pass information.

What is the MOST?

 

Early years by Mercedes-Benz, BMW, Audi 17 car manufacturers and more than 50 automotive parts suppliers to jointly develop technology, is the world's most advanced in-car navigation audio and video technology, but also high-end automotive and in the low-end car audio and video technologythe difference is mainly used in the Mercedes-Benz, BMW, Audi, Porsche, Land Rover and other high-end models.


MOST Technology Advantage
First, MOST use optical fiber allows increased the amount of information transmission, so that the sound
Frequency, interference-free transmission of video control signals and signal mixing, to meet the full vehicle information transmission and environmental requirements, car noise environment at the same time because there is no ground loops, high-speed transmission of data, prevent data from electrical interference.


Secondly, MOST supports Plug and Play mechanism (Plug and Play), so you can insert or remove devices directly MOST pass control network operation, to increase the expansion, maintenance, and use of convenience.


Finally, the MOST standard data transfer rate of 25Mbps, the latest MOST150 standard maximum data rate of up to 150Mbps, 60 can also be separated into a transmission channel bandwidth of 25Mbps, 15 of MPEG-1 video encoding channel, these may be designers re-configuration, planning and deployment.

MOST Applications

Currently, MOST networks are widely used to connect a car navigation system, digital radio, display, a variety of devices such as car phones and DVD, its high scalability and compatibility at the device level, especially for car audio, high-painting quality DVD audio and video compression can be efficiently solve.

Based on these advantages, the MOST bus technology is BMW, Mercedes-Benz, Audi, Porsche, Chrysler, Ford and other many luxury car original manufacturers; German Bosch (Bosch), United States Delco (GM General Motors's respective departments), Japan's Denso (TOYOTA Toyota car'stheir departments), the German Infineon (Infineon), first-line car electronics suppliers; British Linn Products (the precision Sound Design Company), Motorola, USA, the Netherlands, Philips, Japan Sony car audio and video equipment manufacturers widely adopted.

MOST ApplicationsHowever, due to technological security, cost control, factors such as language differences, most of the original manufacturer vehicle factory configuration is low, some features are hidden or not compatible status quo has been unable to meet the growing number of today's consumers are more convenient, and more comfortable, more comprehensive automotive demand for multimedia features.

MOST solutions

In summary, the automotive aftermarket is an emerging huge market, and the maturity of the MOST technology makes the original car screen upgrade, car audio upgrade, the installation of the navigation system, visual reversing system functions can be realized easily.

 

Hwaying MOST fiber products processing advantage afterloading enterprises with many famous automotive jointly developed several sets of new in-vehicle information processing platform based on the MOST fiber optic gateway technology and vehicle equipment specification, it can be an external audio, video and control signals via the automotive MOST fiber-optic network seamless link to the original car multimedia system, driver assistance systems for the the vehicle equipment Ho application provides powerful processing capability, BMW, Mercedes-Benz, Audi, Porsche, Land Rover and other varietyend models automotive MOST (Media Oriented Systems Transport) infotainment network upgrade best solution!
