Digital TV Stream

 MMDS Solution 

Nowadays, when analogue TV distributing networks provide neither quantity nor quality of programs, forming digital packages of TV programs is an alternative solution. It allows to save frequency resource and to increase program capacity and quality. Using MMDS (Multichannel Multipoint Distribution System) technology it is possible to deliver up to 60 channels (QAM64 modulated) and to cover ranges of up to 50 km. MMDS transmitter signal can be used by either a subscriber or CATV operators. The fact that signals used in CATV network  and in MMDS transmitting system are of the same format considerably simplifies interaction between them. Thus MMDS signal received by subscriber’s converter can be fed into any  CATV network without processing. At that Conditional access system can be „end-to-end”, in other words signals scrambled by MMDS transmitters remain encrypted when transmitting in CATV network if they have been received by subscriber’s MMDS converter and have been fed into a CATV network without processing. In order to feed a signal received from “on-air” system into a CATV network, it’s enough to amplify received signal and to combine it with CATV signals.
