Established in 2005, Shanghai Key Lab of Digital Media Processing and Transmission is directed by Science and Technology Commission of Shanghai Municipal Government. It was based on the institute of Image Communication and Information Processing of Shanghai Jiao Tong University, and co-built by Institute of Wireless Communication Technologies of Shanghai Jiao Tong University.
The lab aims to become the top class lab in China and the leading lab around the world in the field of digital media processing and transmission. It focuses on the application of basic research and the service to meet enterprises' needs. It has formed a high-level research team to complete a series of advanced achievements, to grasp the key technologies, and to get its core intellectual property rights.
There are over thirty staffs in this lab, including eight professors, twenty one associate professors and senior engineers. Among them, one professor has been announced as the distinguished professor in Cheung Kong Scholars Program organized by the Ministry of Education, and another professor has won the National Science Fund for Distinguished Young Scholars. Besides, the lab has also invited more than ten international renowned scholars and professors to be visiting professors and researchers. Recently we have gained two second prizes of State Science and Technology Awards, and thirteen provincial and ministerial science and technology awards.
This lab is not only a center for research, but also an incubator for talents. A group of experienced teachers, who are from the Institute of Image Communication and Information Processing and the Institute of Wireless Communication Technologies, have fostered over 200 students by the end of 2009 in the fields of Communication and Information System, Signal and Information Processing. These students include PhD students, Master students, and Master students of engineering,

We proposed our digital television broadcasting standard with our own intellectual property right. It solved many difficulties such as how to use single frequency carrier to transmit digital television data in high capacity and high speed, and how to form a network using single frequency carrier. This standard has achieved ten patents, and it has become the major part of the CTTB (China Terrestrial Television Broadcasting). In 2008, CCTV (China Central Television) has adopted it to transmit HDTV channel. And now more than thirty cities have adopted this standard for the terrestrial broadcast of digital television programs. Besides, the fourth version of decoding chip have been taped out and been put to mass production. TOSHIBA, Samsung, TCL, DVN (Shanghai), PIXELA (Shanghai) and some other companies at home and aboard have adopt this chip to produce HDTV multi-function machine, set top box( which is used in Large Area Fixed Reception project), and PC portable devices.
We proposed the mechanism for high-speed wireless transmission (over 350 km/h), which realized forming a synchronous single frequency carrier network in large area. It had been successfully applied in the rescue system of Shenzhou VI and Shenzhou VII spacecraft, and it won the First Prize of Shanghai Science and Technology Development Award in 2006. Besides, we also completed the single frequency carrier network system for transmitting TV data at a high speed along the railway. After evaluation, the Ministry of Education gave a high praise to this system, believing it was the No.1 system in China and also the leading system all over the world. Until now, we have published seventeen excellent papers, have owned twelve patents, and have realized three technology transfers.
We successfully designed the first HD nonlinear edit board, which has reached the international leading level. We proposed an intelligent and networked HD program production system, which is based on JPEG2000 and has solved the bottleneck of available network bandwidth for producing HD programs. Besides, we successfully developed the prototype of integrated display system for HD film. This system firstly interlinked film decoding system with projection system seamlessly, which enhanced the security of total system.
We proposed the framework of intelligent video joint processing and transmission. By establishing visual selective attention model, we formed a mechanism to obtain as much as possible useful information from limited system resources. By utilizing quaternion wavelet transform, we can directly estimate 2D disparity from an uncalibrated natural image. Recently, we have won the first prize of automatically video search in TRECVID2007, and have published 12 excellent papers in IEEE Transactions.
We have finished a platform development for IPTV bandwidth pushing and content integration on 3TNet. This platform can provide the general front-end for IPTV on 3TNet, which support both SDTV and HDTV, and push a great amount of data with 91 SDTV channels, 1 HDTV channel, and 24 satellite TV channels. Recently, this platform has been applied into the cable network upgrade and reconstruction in Shanghai Jiading and Qingdao.
