A vehicle most network system

Abstract

The invention provides a vehicle-mounted MOST (Media Oriented Systems Transport) network system. The system comprises at least two vehicle-mounted MOST networks, at least one bridge and a flow media data packaging module, wherein each vehicle-mounted MOST network comprises a plurality of nodes; the bridge is used for connecting the vehicle-mounted MOST networks; the flow media data packaging module is used for packaging a program flow which is requested by a user through a video into a program flow module group; each node comprises a timing monitor, a main controller and an MOST network controller; the timing monitor is connected with the main controller and the MOST network controller, and is used for monitoring the main controller and the MOST network controller; and when the main controller or the MOST network controller breaks down, the main controller is controlled to enter a skipping mode. The vehicle-mounted MOST network system provided by the invention expands the existing MOST network and can defend network faults; and flow media data is packaged and transmitted, so that the transmission process of the program flow in a network is simplified and transmission channels are reduced.

Description

technical field [0001] The present invention relates to media oriented systems transport (Media Oriented Systems TransportMOST) technology, in particular to a vehicle-mounted MOST network system. Background technique [0002] As a vehicle multimedia network bus, the MOST network is mainly responsible for the data transmission of vehicle infotainment and telematics equipment. The MOST network uses optical fiber as the transmission medium to transmit entertainment information in a ring topology. figure 1 It is a structural block diagram of the existing MOST network system, such as figure 1 As shown, the MOST network can have a maximum of 64 nodes, that is, a maximum of 64 receivers can be connected in series and installed on collective transportation vehicles for each user to choose their own different entertainment, which limits the scalability of the network structure. [0003] The host acts as a platform for collecting, integrating, and distributing all information in the ...

Problems solved by technology

However, if you want to provide GPS to every user on the collective vehicle, you need to use dozens of GPS receivers, and the hardware cost is high

[0007] In short, the existing MOST network has limited scalability, low fault defense capability, and cannot communicate with other automotive network systems.

If it is necessary to provide in-vehicle TV and GPS positioning for each user on a collective vehicle, the cost is high
