摘要
分析了基于802.11b/g 无线通信技术在无线可视电话中进行数据传输的优点以及 MPEG-4协议在无线视频传输中的优化思路。在 ARM9平台上给出了一种基于 SIP 协议的 MPEG-4嵌入式无线可视电话终端的解决方案,并给出终端的具体的软、硬件的设计方法。实验测试表明,系统视频流畅、语音清晰、实时性强、具有很好的兼容性。
Anlayising the merit of 802. 11b/g wireless communication technology used in wireless videophone and MPEG4 protocal arithmetic optimize in the wireless video transmission. One embedded wireless videophone of ARM9 platform base on sip and mpeg4 solution was given. The project of hardware and software design is proposed. Test is shown that the real-time communication of audio and video is achieved.The system is more compatible for eomforming to open protocols.
