Abstract
Recently, requirement has been increasing for large capacity optical network, for example, for a video signal distribution system in broadcasting studio[1], which has been undergoing a process of complete digitalization. A wavelength-division and time-division hybrid multiplexed (WD/TD) network[2] is an attractive candidate for this purpose, because the attainable multiplexity is given by the product of WD and TD multiplexities. In order to realize WD/TD network, WD/TD channel discrimination and tracking control when receiving a channel are indispensable techniques. In this paper, a highly intelligent WD/TD channel selector is described for practical broadcasting studio application. Results for WD/TD channel selection and tracking control are shown to demonstrate the developed selector performance.
