Wireless multimedia communication technology is the perfect combination of wireless communication technology and multimedia technology, brings enormous business opportunities in the information industry today. In the field of communications, voice, image, video, and other communications into one service delivery as the HotSpot. This article from the actual needs of intelligent transportation systems, wireless video transmission in intelligent transportation systems research and design. The design of wireless video transmission system based on embedded Linux as a development platform, using the RTP Protocol the H.264 encoding standard, using classic c/s structure, to PcDuino Development Board as a server-side, video compression, and send;To PC machine as the client, video packets received and decompress plays, as well as the storage and playback of video. Systems to compress a video transmitted in real time to the control centre over a wireless network, then using existing decoder to extract the video and finally echoes in the QT interface. Its characteristics are better able to adapt to a variety of types of networks, as well as more efficient encodes to reliable, secure, and convenient video.

Wireless multimedia communications technology is the perfect combination of wireless communication technology and multimedia technology, has brought unlimited opportunities for today's information industry. In the communication field, Youyi voice, image, and video transmission set in the communications business is one of the hot spots. From the actual demand of intelligent transportation system starting on Intelligent Transportation wireless video transmission system was designed and studied. The design of the wireless video transmission systems primarily for the development of embedded Linux platform, using RTP protocol H.264 coding standard, using a typical C / S structure to PcDuino development board as a server for video compression and sending; to the PC as a client, video packet reception and decompression playback, as well as save and playback video. Good system can compress real-time transmission of video over a wireless network to the control center, and then use the existing decoder to extract the video, the last in QT interface echo. Its characteristics are better able to adapt to all types of networks, and a higher coding efficiency can be reliable, safe and convenient video transmission.

Wireless multimedia communication technology is the perfect combination of wireless communication technology and the multimedia technology, brought infinite business opportunities for today's information industry. In the field of communication, and to voice, image, video and so on communication service transmission one hot. This article from the actual demand of the intelligent transportation system based on wireless video transmission system, intelligent transportation system is designed and researched. Wireless video transmission system in this design mainly uses embedded Linux as the development platform, H.264 coding standard based on RTP protocol, using the typical C/S structure, uses the PcDuino development board as the server, video compression and transmission;Using PC as client, the realization of video data packet reception and decompression and playback, video storage and playback. The system can be compressed video over a wireless network real-time transmission to the control center, and then use the existing decoder decompresses the video, finally to show in the QT interface. Its characteristic is better able to adapt to various types of network and has higher efficiency of coding, can be a reliable, safe, convenient transport video.
