Abstract: Aiming at the problems of developing software with Tuner card SDK or Video for Windows(VFW), which depends on concrete equipment and high cost, this paper proposes a network television system based on Microsoft DirectShow and COM technologies. The system enhances the generality and declines the cost. And it uses IP multicast technology to transmit data, so that it saves network bandwidth resources and improves the efficiency of data transmission.
