Design And Implementation Of Bottom Software For High Definition Non-Lined Compile System Based On JPEG2000

Nowsdays, digital television has been developed rapidly in our country. The need for high definition television programming couldn't be satisfied. Therefore, it is necessary to design a kind of effective high definition non-lined compile system which is based on network. This kind of system is ungently needed by television makers.This dissertation introduced the design and implemention of bottom software for a kind of high definition non-lined compile system based on jpeg2000 in windows, which would be explained in three aspects including driver design for hardware card in non-lined compile system, capture application and plugin design for non-lined compile software. The driver for hardware card in non-lined compile system could be used in capture for both uncompressed and compressed high definition data. This dissertation first introduced the structure of hardware card in non-lined compile system. Then the driver for the hardware card was designed with techniques including interrupt, DMA, MDL, kernel Event and"multi-frame buffer"which was designed especially for capturing uncompressed high definition data with the speed up to about 125MB/S. The drvier could be used to capture uncompressed high definition data successfully.Capture application was designed in multi-thread structure with the technique called"secondary buffer"for the need of capturing, analyzing, reconstructing and storing at the same time. A J2M reconstruction algorithm was designed to analyse and store the data real-time successfully with the consider of the structure of J2M and encoded stream from hardware card in non-lined compile system.In the process of plugin design, the first import plugin and compile plugin for jpeg2000 were designed in Premiere to complete the work chain of high definition non-lined compile system based on jpeg2000 in windows.In the end, the dissertation summarized the design and implemention of bottom software for high definition non-lined compile system based on jpeg2000 in windows and gave some advice and expections to the possibile improvement and development.
