    Question sat quality differences


    i have been noticing a vast difference in picture quality ,brightness and contrast as well as sound level transmissions between different sats.
    is there a standard that they should use for these settings?or is it up to the provider?
    or,,are they all transmitting the same protocols,,and its a reception thing related to signal strength etc?
    any insight is appreciated
    cheers,,,dave

    well, there is an int'l. standards for things related to telecoms. maybe the only difference from these individual satellite transmission is how much transmitting power output (in watts) each satellite have. (low watts = poor transmitting power)

    The picture quality depends on how much compression they use when uplinking. More the compression poorer the quality. They need to do so to reduce the costs of expensive bandwidth.Signal strength (quality) depends upon the uplinking power used in the ground station mostly of the time.

    PS: If sound is little less then it may be because the sound engineer at that station may have very sensitive ears so he would thought everyone like that
