Abstract：We made fruitful progresses in the Digital Media Understanding Algorithm Evaluation Platform，Intelligent Surveillance Video Analysis System and Interactive IPTV Search System， with breakthroughs in key technologies that are related to these areas. Our team managed to publish 9 important papers， including 4 on top artificial intelligence conference International Joint Conferences on Artificial Intelligence （IJCAI）， 1 on another top artificial intelligence conference Twenty-Seventh Conference on Artificial Intelligence （AAAI） and 1 on IEEE Transactions on Multimedia. These outstanding results build a solid ground for the following research work. In the Digital Media Understanding Algorithm Evaluation Platform part， we collected over 2000 hours of video data， making the total amount over 20TB. These data greatly supported our research work. We also participated in organizing several International Algorithm Evaluation Contests， which gained the project a wide-spread reputation. In Intelligent Surveillance Video Analysis System， we studied several topics to improve robustness of the system， including Vehicle Detection and Tracking under Single Camera， Video Fusion and Registration under Multi-Cameras and Spatial-Temporal Feature Extraction algorithms. In Interactive IPTV Search System， our research results are implemented in the backend of Oriental Cable Network （OCN）， the Cable TV Service Provider in Shanghai. We are also developing search servers for IPTV systems of China Telecom， which will be brought online early next year as planned.

Key Words：The digital media understanding algorithm evaluation platform；Intelligent surveillance video analysis system；Interactive IPTV search system
