Measat 3 at 91.5°E-Reliance Digital TV : curent quality status in central Europe

.
         RELIANCE Digital TV - simple function which defines the technical aspect of reception in Central Europe
                                                                  click for enlarge

                   
curent quality status on 2011 : then the operator has made changes to transmission parameters during the last
year (FEC,SR,f), occurred in October last year to further increase the number of channels in individual packets,
which ultimately resulted in a significant decrease in quality of reception in Central Europe and the quality
condition persists to this day !                          

quality status on 09.2010 : lock the carriers is unstable and non-cyclical oscillates in one second intervals in a wide
range of amplitudes of the quality from MER=5 dB (what is the level of detection for FEC protocol 5/6 ) to MER= 8+dB
which is the fair gain margin of more than MER=2 dB ! Even when the level of radiated power EIRP continuously oscillates
in the measuring point, measuring results over a period of 120 min. confirmed that the average level of gain on DVB-S
carriers BIG TV  was about 1.5-2 dB dB lower than the packet carriers SUN Direct.On the basis that the period of
measurement and aggregation of data was only 120 minutes, I can not objectively say that the quality of the reception
packets from a broadcaster Sun Direct is higher by an average of MER=1.5-2 dB,compared with Reliance BIG TV .This
qualitative status I identified only in a defined period of time
