为了实现远程监控图像的清晰,并保障系统的实时性和可靠性,需要高效率和高质量地进行视频压缩,无差错地进行快速网络传输,有效地进行命令控制。通过优化最新的H.264视频编码算法,设计有效的传输方案和引入自适应的传输机制来解决远程活动图像传输系统中存在的清晰、实时、高效、可靠性问题。实验结果表明:改进后的算法较原有的T.264编码方案速度提高了30%以上,设计的传输策略在保障传输速度的同时,能有效地适应不同的网络环境。在系统中引入的几个关键技术对远程视频传输系统提供了有力的支持。
In order to achieve the clarity of remote monitoring images and ensure the real-time and reliability of the system, video compression is required with high efficiency and high quality, fast network transmission without errors, and effective command control. By optimizing the latest H.264 video coding algorithm, designing an effective transmission scheme and introducing an adaptive transmission mechanism to solve the problems of clear, real-time, high efficiency and reliability in the remote moving image transmission system. The experimental results show that the improved algorithm is more than 30% faster than the original T.264 coding scheme, and the designed transmission strategy can effectively adapt to different network environments while guaranteeing the transmission speed. Several key technologies introduced in the system provide strong support for the remote video transmission system.
