摘要
本文介绍了一种新的多点会议电视联网方案。它使用了总线式联网控制方案,该方案采用树状网络结构,会议过程由网络中的任意一个指定的会场进行控制。与已有的方案相比,它的特点是容量大、组网方便和控制灵活。它既可以满足召开电视会议的一般要求,又能节省图像的传输信道。在对图像质量和效据率要求较高的场合(例如8.448Mb/s,2.048Mb/s和384kb/s)下,其优点尤为突出。
This paper Presents a new multipoint videoconference networking scheme, it uses the bus-zike networking control method, which is based on the tree structure network. The procedure of meetings can be controlled by any pre-specified point in the network, compared to existing schemes, the proposed scheme is characterized by its large content, convenient networking and controlling; it can not only satisfy common reqirements of videoconferencing, but can also save image transmission channel. In the circumstances of higher image quality and higher transmission bitrate (8.448Mb/s, 2.048Mb/s, 384kb/s), its advantages are obvious.
