摘　　要：针对无线视频传输系统的难点,提出了双模视频传输系统。该系统在硬件上采用OMAP3530芯片,编码上使用H.264编码,充分利用了H.264标准在数据压缩率和网络友好性等方面无可比拟的优势。无线传输利用TD-SCDMA和CDMA20001x两种3G无线传输信道,采用双模调度和管理算法提高了网络可利用带宽,增加了视频传输的稳定性。Wireless video transmission system for the difficulty is proposed dual-mode video transmission system. The system uses OMAP3530 chip in its hardware. H.264 code is applied in coding. H.264 standard has splendid advantages in data condensing rate and net friendliness. In transmission part, two module-TD-SCDMA and CDMA20001x are providing to transmit at the same time. The module transmission can increase the net usefulness belt breadth, and add the stability of the video transmission.
