With the constructions of highway and railway infrastructure,the development of transportation business and tourism is forging ahead.In order to enhance services and inspire more customers,many passenger-transport companies are replacing the old-fashioned disk players with more flexible VOD systems on their buses and trains.Focusing on the cost-effective problem,it introduces a scheme of implementation of the embedded multiplex VOD system based on NiosⅡ.The system uses custom logic module to implement high speed multiplex DMA in method of Ping-pang operation.In response of user terminal,the decoded data is sent to the corresponding port,which satisfied the requirement of multiway real-time play.
