Problems solved by technology
MOST is currently the most widely used high-speed multimedia network transmission protocol in in-vehicle information and communication technology. However, the first-generation MOST network does not yet have the image transmission function, and has not yet formed standard equipment in the huge aftermarket, which also shows the life cycle of the vehicle industry. From technology development to formal introduction into the market, it will take longer than the electronics industry to test the function and safety of products

A multimedia data sharing system applied to an MOST network includes a service management module, a data chain control module and a protocol converting module. The service management module is used for analyzing all service states of the multimedia data sharing system and managing a frequency band needed by each service or a memory configuration, and filling the service state after analyzing and the configuration result into a service management table. The data chain control module is used for controlling a system data stream based on the information which is configured in the service management table by the service management module and managing programs. The protocol converting module is used for acquiring the data from a channel register based on the information ins the service management table to perform a management operation of MOST chain, and executing a packing operation or a unpacking operation to the data grouping so as to access the MOST network.
Description
technical field [0001] The present invention relates to a data sharing system and method, and in particular to a multimedia data sharing system and method applied to a MOST network. Background technique [0002] In the future, mobile communication technology will enable cars to be mobile offices or small theaters, integrating wireless communication equipment, multimedia networks and customized hardware and software platforms to provide digital entertainment services. Automotive Service includes at least in-vehicle information communication technology (Telematics), instant multimedia entertainment on-demand service and plug-and-play service of portable devices. [0003] In-vehicle information and communication technology services (eg, Remote Diagnostics) need to connect the car to the back-end server to send and receive information to access network resources (eg, home network, electronic toll collection, road navigation, etc.). The real-time multimedia entertainment on-dema...
