A multimedia data sharing system and method for a MOST network is disclosed. The system provides a service management module, a data link control module, and a protocol conversion module. The service management module provides state analysis and management for all services of the multimedia data sharing system and records analyzed service states and configuration results in a service management list. The data link control module performs a control and management process for system data streams based on information stored in the service management list. The protocol conversion module retrieves data from a channel register, based on the information stored in the service management list, to perform a MOST link management operation and implements a packaged or an unpackaged operation to data packets for access of the MOST network.

Multimedia data sharing system and method for MOST network

An apparatus and method estimates the adaptive wireless channel for a moving vehicle. Once a packet is received, this invention analyzes a channel interference index for the moving vehicle, and computes a first recursive parameter, a second recursive parameter and an interpolation number. Based on the first recursive parameter and the interpolation number, partial channel information is calculated for further channel estimation by using an interpolation. The parameter of an equalizer is also immediately updated. Cooperating with a decision feedback scheme and based on the second recursive parameter, channel tracking is performed. In order to achieve the adaptive channel estimation for wireless access on the time-variant vehicle environment, the parameter for the algorithm for performing the channel estimation is adjusted.
