| 8. | However , without any available theory instruction , it has lots of problems at the beginning of its development . furthermore , there is no marketing problems in the traditional education area , so study and research are requested even more
但是在行业发展之初必然存在很多问题，而且没有现成的理论进行指导，特别是在传统教育领域中不存在的营销问题，更是需要进行探索和研究。 |
| 9. | The dynamic bit rate allocation module receives relevant data from the loss rate of multi - media data packet , jitter , delay , and compares these data with predefined values to make one of these 3 decisions that : decrease the video bit rate ( stat = decrease ) , or maintain current video bit rate ( stat = hold ) , or increase video bit rate ( stat = inccease ) . the video bit rate will be adjusted according to the decision and the total bit rate is changed accordingly . in this way the impact of network environmental variation is settled , and consequently the adaptability of videoconference systems in remote education area is improved
整个模型从rtcp协议获得多媒体数据包丢失率( lossrate ) 、抖动( jitter ) 、延时( delay )的相关数据，这些数据与预先设定好的阀值作比较，得出减小视频位速率( stat = dectease ) 、维持视频位速率不变( stat = hold )或增大视频位速率( stat = increase )的决定，模块根据这些决定对视频位速率进行相应的调整，从而总的位速率也相应变化，这样可以减小由于网络环境变化而带来的影响，从而提高视频会议在远程教育应用中的实用性。 |
| 10. | Based on the research of videoconference systems of h . 323 protocol over ip networks and the author ' s experiences of implementing h . 323 videoconference systems in remote education area , in this thesis the main factors that affect videoconference quality are analyzed , and a dynamic bit rate allocation model is proposed and partly implemented . this model is designed to dynamically allocate bit rate for multi - media data flow ( including audio data and video data ) in fixed bandwidth network environment . when continuous multi - media packet losses are detected in ip based h . 323 videoconference system , the bit rate of video data is adjusted meanwhile the bit rate of audio data remains unchanged , and the bit rate allocation of multi - media data ( including audio data and video data ) is optimized as a whole effect
本文结合作者在h . 323视频会议系统应用于远程教育的经验，通过对现有的基于ip网络的h . 323协议视频会议系统的研究，分析了影响视频会议质量的原因，提出并部分实现了在固定带宽的网络环境下，基于ip的h . 323视频会议的多媒体数据包发生丢包、抖动或延时时，保持音频数据位速率不变，通过对视频数据的位速率的进行调整，最终实现旨在提高视频会议语音质量的多媒体数据位速率动态调整的模型。 |
