摘要
为提高视频模块在汽车仪表中应用的可靠性,设计了一种防解析失败的解码策略。通过设计阻抗匹配电路,优化解码策略,实现了汽车液晶仪表视频模块。测试分析发现,该视频模块的解码成功率100%,提升了视频模块的可靠性。结果表明,该模块可解码显示传统算法无法解码的视频流,降低了仪表开发的风险,符合市场发展趋势。
To improve the reliability of video module in automobile instrument,a decoding strategy was designed to prevent parsing failure.By designing impedance matching circuit and optimizing decoding strategy,video module of automobile liquid crystal instrument is realized.Test analysis shows that the decoding success rate of video module is 100%,which improves the reliability of video module.The results show that the module can decode and display the video stream that cannot be decoded by traditional algorithm,which reduces the risk of instrument development and conforms to the market development trend.
