摘要
为了进一步提高视频传输质量,充分发挥网络视频在教学中的作用,提出了一种新的基于智能数据流的传输模式,摒弃了以往单一改善网络传输环境的思路,建立更加智能的视频源服务环境,并详细阐述了智能数据流传输的几个关键技术。最后,从网络接收延时方面对基于智能数据流传输的网络视频教学系统进行仿真试验。实验表明,该系统可以有效地减少网络接收延时,提高网络视频教学的服务质量和效率。
A new transmission mode based on inteRigent data stream is proposed to improve the quality of video transmission and give the full scope to teaching by network video,the former thinking which is only to improve network transmission environment is abandoned.And then,a better setting with more intelligent service of video source is established,and several key skills during transmission in details are stated.Finally,simulation experiment of network video teaching system based on intelligent data stream is conducted on the aspect of network transmission delay.The experiment shows the system can effectively reduce the delay of network transmission and increase the quality and efficiency of network video teaching.
