Video/network interface

摘要

A video/network interface device architecture for coupling a telecommunications packetized network to a video/audio continuous stream environment uses separate uni-directional busses for transmitting packets from the video/audio continuous stream environment to the telecommunications packetized network and for transmitting packets from the telecommunications packetized network to the video/audio continuous stream environment. A communications interface module, one or more studio interface modules and a control module are coupled to the uni-directional busses, with the communications interface module at the network end and the control module in the middle of the studio interface modules. A split personal computer interface bus is used by the control module to control the interface modules. Since signals do not have to change direction on the uni-directional busses, the busses may be used at a higher operating frequency than could be done with a single bi-directional bus. <IMAGE>
