Video conferencing systems have been widely used all over the word and bring much convenience to our daily life. With the increase of network capability, users of video conference desire upgrade of video quality more and more intensively. However, the extensibility for large-scale standard-definition video conference is seriously restricted by the ability of decoding multi-path standard-definition video flows simultaneously in conference clients. To solve this crucial problem, we design and implement a DV-based extensible video transport terminal with a combination of standard-definition and low-definition video flows both from a single input DV camcorder. The low- definition video is sampled from the original DV stream and its size and sample rate can be adjusted to accommodate different application conditions. Using this method, our video tool can solve the extensible problem in standard-definition video conference and shows much flexibility in many conference scenes. Based on this video tool, we propose an extensible and flexible architecture for standard-definition video conference which can also be used in high-definition video conferencing systems.
