FHSU's ITV signals are routed to and from the on campus terminal equipment via our campus-wide ITV switch. FHSU also joined the High Southwest Plains Network, or HSPN, a full motion digital network using dedicated switched fiber optics. FHSU does not retain full motion to the HSPN though. Between FHSU and the HSPN only restricted fiber bandwidth is available so FHSU shares bandwidth with other traffic for that connection. Using smaller bandwidth requires some degree of compression.
Compression adversely affects the picture's motion and resolution.
FHSU uses compression technology to retain 3 channels to the HSPN network while using only a single DS3 circuit. FHSU's ITV signals are routed to and from the POP via our campus-wide ITV switch. ATM is a switched digital compressed full screen system. FHSU also terminates this DS3 circuit at each end with a Grass Valley J-Series codec. The remaining 2 networks accessed by FHSU are full screen, switched digital compressed networks.
