| 摘要: |
| 针对无线移动通信网络的客观制约，给出了一种音频同步的基于视频连环画模式摘要自动生成的实用视频服务方案，使得系统在向用户提交连续音频流的同时，能够随着网络带宽条件的变化，按照动态采样频率，基于视频内容选择重要帧递送，并按照与音轨同步的模式播放，从而在降低数据量的同时，满足用户对视频内容综合理解的需求。 |

| Abstract: |
| Aiming at the objective restriction of the current wireless mobile network, a practical video delivery solution based on the automatic generation of dubbing video slides is presented. We guarantee the continuity of the audio stream first, and then select important frames in the dynamic sampling frequency based on the visual content analysis according to the current network bandwidth. Those frames are transmitted and played in a synchronous mode with the corresponding audio track. Our solution can satisfy the user′s requirements for video content comprehension while remarkably reducing the quantity of data flow. |
