Scene Generator Of Two Synchronous Channels

According to the present requirement of technology standards, the generating process of real-time scenes is carefully analyzed; and based on the function of the previous scene generators, the realizing schemes of the software and the hardware are also discussed in this paper. In order to meet the main technology standard of the system, with the study on the generating, transmitting and output technology of two synchronization channels scene generator, the schemes of the software and the hardware are processed.By full usage of the software resources of computer, part of work of the scene generator is accomplished with Windows NT as the operating system.In the design of hardware, PLX9054 is used to realize the control of PCI bridge route, which greatly shortens the period of development. The hardware system with the composition of the PCI functional plug-in structure, realizes the real-time output of 10bit scene data whose resolution is 768*576 in the velocity of 25 frames per second. The new system required two synchronization channels. The synchronization of two channels is realized by two plug-in cared with the same synchronization source.
