| 摘要: |
| WebLearning+是作者开发的基于IP组播的协同学习环境，可伸缩性视频编解码及其自适应组播传输是系统研制中的核心技术。针对WebLearning+中自适应视频组播对编解码器的要求，提出了一种基于行扫描的可伸缩性小波视频编码方法ViCowel。实验结果表明该方法对于视频组播应用具有较好的适应性。 |

| Abstract: |
| WebLearning-plus is a multicast-based collaborative learning environment we developed, in which scalable video coding and adaptive multicast transmission are the key issues. According to the demand of adaptive video multicast in WebLearning-plus for the coder, we present a new scalable wavelet based video coding approach named ViCowel, which is a kind of set partition based on line scanning. Experiments show that it has better flexibility in video multicast applications. |
