Design And Implementation Of The Multi-channel Streaming Media Player

In the fields of detective robot, automotive equipment investigation, videosurveillance, there usually will be a plurality of image pickup head shooting the real-timevideos in a plurality of channels on some of the monitoring equipment. Due to thecomplexity setting conditions of these devices, the monitoring personnel would not beconvenient to observe the video within near distance. Therefore we need a program toremotely playback the multi-channel real-time video stream.In the background, this article according to the specific needs of the project, researchand design a kind of multi-channel media player which is applicable for the detection,investigation and monitoring. After conducting an in-depth research of the keytechnologies of the player, lot of design and optimization have been done to the real-timeperformance and synchronization, In real-time aspect, this paper mainly studies thetransmission strategy of the real-time video stream.were asked the a control a protocol ofreal-time video stream transmission, and the mechanism of transmission control. Also inthe receiving end, through optimized design of the buffer, the highly efficient data packetstrategies has reduced the delay of the receiving end. About the synchronization, thisarticle first discusses the two kinds of strategies of the synchronous transmission, andselects the method based on the time stamp. Then for multi-channel video andmulti-channel real-time video stream the paper designs two different sets of synchronousplayback mechanism.At last,tests show that the real-time performance and synchronization of the player isexcellent, proving the transmission strategy, receiving end delay optimization and thedesign of the synchronization control mechanism in this paper has a very good effect Themulti-channel streaming media player has a high application value.
