Design And Analysis Bmbedded Video Monitoring System Base On TVP5150

How to get a quick, efficient and low power consumption of the video systemhas become a hot issue of research in the file of embedded systems facing with therapidly development of Internet, the application needs of portable products armincreasingly common.It is in this society and the market demand, designed TVP5150decodewe chip-based video surveillance system.The TVP5150decoder chip with lowpower consumption, support the main featurews of a variety of high-performanedecoder. Designed this products will be sidely used, play an important role in themarket.In this paper, first discusses the development environment set up a TVP5150Video Surveillance Systems Video. Next discussed TVP5150video monitoringsystem software components, mainly covering the four parts: The first part of thesystem to start the software u-boot; Second part of the Linux kernel; Third part of theblock device driver, the fourrth part of the Linux file system.The core part of thispaper of this paper is to design TVP5150analog video surveillance system. Start witha whole discusses the overall structure of the analog control system and video datastreams. Which focuses on the TVP5150module functions,the video signal into thesystem and the entire video system software design. Finally, to summary and tooutlook the video of TVP5150.The completed work of author work on the Linux platform, set up a theTVP5150simulation video.The system onsists os the IIC bus confuguration toachieve TVP5150video module registers, video processing circuit the SCALER onthe TVP5150module decoded standard ITU-RTB.656video signal modulation andRGB VIDEO signal into three primary colors. In terms of video capture and videodecoding algorithm design more in-depth discussion. MFC video decoder frame afterthe memory address is mapped to the frame buffer device Framebuffer, complete thefinal surveillance video on the LCD momitor display.This important feature of the video system design, low power consumption, to support a variety of standard high-performance decoder, capable of supporting thedemand for portable products. Facilitate the development of the IIC configurationregister quickly to transplant the module into the product, shorten the cycle oftechnology to product conversion.
