PAY-PER-VIEWHeadend configurationA vHOTEL headend can be constituted by separate functional units as indicated in the illustration at right, where DVD players are being usedas video sources. However, the system has been especially designed to make use of IKUSI’s ClassA terrestrial and satellite receiving modulesoperating as “video source plus TV modulator” assemblies; one ClassA receiving module is paired with one CTP-200 scrambler to create onescrambled vHOTEL channel. CV: clear videoA: audioEV: encoded videoApplication example using SDC receiving modulesSIGNAL INTERCONNECTIONThree different interconnection lines must be performed between the SDC receivers and the CTP-200 scramblers:- RF Interconnection : Every module has two antenna loop ports and two VHF/UHF loop ports. Ones and the others are cascaded by the F plugbridges provided. The ports have a proper mission in the SDC receiving modules, while they operate as simple “RF path” in the CTP scramblers.- Video Interconnection : At each SDC+CTP pair there is a SDC→CTP clear video transmission and a reverse CTP→SDC scrambled videotransmission. These transmissions are assured by the video jumpers provided.- Data Interconnection : Each one of the SDC and CTP modules has 2 small 4-pin sockets which are used to install a property communicationbus through the jumpers provided.POWER CONNECTIONAll modules SDC and CTP are +12 VDC powered by the CFP-700 Power Supply. Each module has two DC banana sockets that allow to build apower cascade through the DC plug bridges provided.CONNECTION TO THE CENTRAL CONTROLLERThe headend uses an RS-232 interface to communicate with the Server. Connection is made on the last scrambler module at the right end ofassembly. Example of «vHOTEL» headend for 5 scrambled TV stations. Contains 5 Receiver+Scrambler pairs (SDC+CTP), 1 HPA-120Amplifier and 2 CFP-700 Power Supply Modules, all fixed on 2 horizontally joined BAS-700 Base-Plates.Pay-Per-View169
