VB over IP网关系统的设计

VB over IP System is an important device which connecting DVB broadcast network and IP network. Its function is to convert from DVB ASI signal into IP packets for LAN/WAN digital video delivery. This paper introduces a method of design and implementation of IP-ASI Adapter System. This system’s hardware platform is composed of ARM9 processor and FPGA chip, and this system uses Linux operation system as the platform for software development. This paper introduces the hardware design, the transplanting of Linux kernel and the design & implementation of software part in detail. At the same time, we developed network management software in PC client. Users can control and manage the device remotely using the network management software. And further more, the author gives some opinions about the network protocol involved in this system.
