Organization of regional DVB network on the basis of “Crypton” equipment by example of Lviv region

Reasons of application:

Coverage area of regional transmitting center – 50-60 km for 2-3 national channels and 15-20 km for other TV-channels. Signal distribution interval is significantly decreased in hilly areas. Microwave transmission lines don’t solve the problem. According to statistics, 60-70% of Ukrainian citizens can receive up to 3-4 TV-channels and the rest of citizens 1-2 TV-channels only. There is no any wide application for satellite broadcasting reception (high cost of receiving equipment, channels encoding, including Ukrainian channels; lack of regional channels in signal).
