Note:
For digital transmission, no conclusions can be drawn about the reception quality based on the quality of
the picture and sound. The picture and sound are always perfect to a certain transmission quality, below
which the signal cannot be reproduced. Only within a small threshold range can you notice characteristic
blocks in the picture (“brick wall effect”) and constant interruptions to the sound. Broadcast quality can
only be determined based on measurements (BER, MER).
Press
ESC
