摘　　要：模拟视频信号解码既是视频应用的重要部分,又是后级数字信号处理的基础。为了适应于便携式设备的发展,研究了一种以TI公司的视频解码芯片TVP5150为核心、MSP430F2013单片机为控制器件的低功耗视频解码模块。单片机控制TVP5150的I2C总线以及与PC机的串口通信。文中主要阐述了系统硬件设计、PC机与单片机通信软件设计(包括PC机部分和单片机部分)、单片机I2C总线控制软件设计以及模块输出信号的说明等。本模块的模拟视频信号解码为符合ITU-R BT656标准的数字YCbCr信号,具有良好的应用前景。Decoding analog video signal is a important part of video application, and it is the base of the following digital signal processing. This paper introduces a low-power video decoding module, which is based on low power video decoder TVP5150 produced by TI. MSP430F2013 MCU is a control device. The MCU controls TVP5150＇s I^2C bus and serial port communication of PC. It explains the design of the system hardware, the software design of PC and MCU communication（ including PC part and MCU part） , the I^2C control software and the explanation of the module output. This module make the analog video signal decode to digital signal accord with ITU-R BT. 656 standard, and has good application prospect.
