deva,
but which makes difference. Even cable operator use dish to receive the channels from satellite. So, the signals are sent via the cable through all houses from cable room. In that case, the signal which hathway stb receives also is digital no??
I am confused here how stb differes in receiving signals. Till now i thought only the encryption technology changes in the STB like MPEG2/MPEG4.
like a bit technical, how the signal are getting delivered from satellite. Is the
tv station will transmit signals in differect encryption? Where the actual encryption happens (like mpeg4/mpeg2). . do you have any idea.. if yes, can you share.
for receiving signal from satellite - satellite receiver(stb) is must.
in cable we are getting signal through cable so cable stb is required.
MPEG2/MPEG4 is not encryption technique,, it is compression technology...irdeto,NDS is are some encryption technology..
yes tv stations use different encryption techniques but we didnt care about it ...dth operators receive that signal like cable tv operator does... again they compress it using mpeg2/4 and then encrypt the signal and then again the uplink their signal in satellite...
