The Media Oriented Systems Transport (MOST) automotive multimedia network standardization organization’s Advanced Driver Assist System (ADAS) network enables HD camera streams tailored to automotive systems’ 360° top-view systems. MOST Technology is used in more than 150 car models’ infotainment systems.
- Transmits HD video streams from up to 8 cameras using up to 1.2 Gbps total bandwidth
- Cameras connected to a central node in star topology over coaxial cable
- 10 ms latency
- Different branches can be built with various topologies including star, right, tree, and daisy chain
- The network interface controller branches can be hot-plugged or disconnected without interrupting streaming data
- Can offer low reflections at up to 100 meters depending on bandwidth and cable/connector quality
No microcontroller required with the remote control feature
Safety requirements don’t allow for streaming data to be interrupted or delayed. MOST allows for an efficient transport of streaming data with low latency and determinism through its multiplex architecture. Conversely, other solutions may require additional communication processors or addressing information, or break data up into packets that require individual examination through each device on the route, which wastes bandwidth.
The coaxial cable, which MOST says is the industry standard cable for transporting high-frequency signals, allows for bidirectional communication and power using a single cable. Coaxial cables provide shielding standard and are relatively low cost. They also allow for up to several Gbps transfer rates, and are EMC-proof.
