Car MOST audio and video system

1. 1.Product description:

2. MOST (Media Oriented System Transport) is the abbreviation for Media Oriented System Transport. The vehicle-mounted MOST audio-visual system uses optical fiber as an information transmission medium to transmit digital signals.

3. Features: light weight, can support high-quality multimedia transmission, product modularity, no radiation, no crosstalk.

2. Product application

At present, MOST network is widely used to connect car navigation systems, digital radios, display screens, car phones and DVDs and other devices. It has high scalability and compatibility at the device level, especially for car audio and video. High-quality DVD audio and video compression can be efficiently resolved. Figure one

MOST solution

The automotive aftermarket is a huge emerging market, and the maturity of MOST technology makes the original car screen upgrade, car audio and video upgrade, installation of navigation system, visual reversing system and other functions easily realized.

In the early days, LIN Bus (20kbps), CAN Bus (1Mbps), FlexRay (10Mbps), Bluetooth 2.0 (3Mbps), etc. all performed poorly in terms of transmission rate, and are gradually being performed in terms of transmission rate, stability, and anti-interference. Replaced by the MOST multimedia bus protocol with higher superiority and applicability.

3. Components and installation

1. POF;

2. Attachment materials conforming to MOST standards;

3. Audio and video terminal equipment for various applications.

Modern cars have become more intelligent due to the densely packed body sensors. How to transmit and process the data and control signals between the various sensors of the car, the selection of the car bus scheme has become extremely important.

Advantages and characteristics:

The system uses networking protocols such as MOST to construct information channels for multimedia informatization such as car audio and video. The specific connection is shown in Figure 2. Passengers can enjoy music, movies, video games, shopping, Internet and other services on their seats through the POF network.
