Analog/digital networks for real-time video distribution with extra computational capabilites
Anatoliy S. Gordonov · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1997
We are going to consider a logical and physical architecture of an analog/digital video network. These networks allow full-screen real-time motion video distribution concurrently with regular network activities without slowing them down. The analog/digital video network uses two parallel communication media: analog - for transmitting video images and digital - for data transmission. Any video terminal in the network can be connected locally to a computer or to the analog video bus. A set of video terminals connected to the analog medium defines the current configuration of the video network. The configuration of the video network depends on a number of random real-time events. The configuration can be automatically changed by computing a set of the specially defined functions. These functions will be various for different applications. The computation of the functions and the resulting dynamic changes in the network configuration constitute the adaptive characteristic of the video network. A regular digital network is used to control the video network. For this purpose, a special management protocol was developed.© (1997) COPYRIGHT SPIE--The International Society for Optical Engineering.
