On Mar.11, Prof. Hou Ziqiang gave a brilliant lecture on sonar technology, network new media, network TV and next-generation Internet for all the researchers and postgraduates in IACAS.
At the beginning of his lecture, Prof. Hou Ziqiang talked about the latest development of sonar technology. Then he furthered his lecture by introducing the status quo of network new media and network TV. In his lecture, Prof. Hou pointed out that new media is a revolution in media field, here the new media including mobile and network TV. All these kinds of new media penetrated into every corner of the world. As the download method of P2P and the upload method of fluid media are different from the traditional way, more and more ordinary customers could publish the things they like on the media. In addition, network new media is developed on the basis of interactive media. In the interactive process, customer is considered as the center and they become the participants in the whole activity. They have fresher experience than the traditional users. Prof. Hou also mentioned that the new media was successfully applied in the Beijing Olympic Games to illustrate that the number of network new media users is increasing.
In the second part, Prof. Hou turned his focus on network TV. He said the condition for the combination of internet and television is more and more mature. The next generation internet is required to have the function of providing all round service for more than one device at the same time.

The website is designed like a television. Customer can use the remote controller to choose the channel.
In the last part of the lecture, Prof. Hou introduced his strategic idea about next generation internet. He started this part from the hourglass model of network. Though the bottom transmission protocol and the top application protocol are various, the TCP/IP protocol, lays between is used up to now unchangingly. To some extent, this protocol has become the bottleneck in the development of internet. As for the future development of internet, he mentioned 3 methods: evolution method, overlap method and innovation method. Evolution method namely is the newly developed "Request for Comments" (RFC); overlap method means realizing "IP information horizon" by overlay network; innovation method means to establish a new generation network. Finally he talked about the standards of P2P, the next generation network, the comparison of TCP/IP and metabolism and so on.
The brilliant lecture was followed by a warm discussion. The audience said they all benefitted a lot from the lecture.
