Implementation and evaluation of the robust high-quality video transfer system on the broadband Internet

High-quality motion picture increases the Internet traffic because of the wide spread deployment of high-speed applications over the Internet. Nevertheless, since the Internet is a best effort network, it has no reliable end-to-end communication. FEC (forward error correction) can be used to repair the damage to communication quality due to packet loss. The growing requirement of FEC for high-quality video transmission is inevitable on broadband Internet. We have designed and implemented FEC, and integrated it to our developed video transfer system named "mpeg2ts". Our goal is to make it possible to deploy this system on the broadband Internet. However, the problem with constant redundancy of FEC is that weakness to fluctuation of network condition. To resolve this problem, in this paper, we design and evaluate an efficient FEC method for high-quality video transmission, and integrate it into a system to deploy it on the real broadband Internet. Moreover, transmission experiment demonstrates availability of developed system on the network.
