Does SPDIF completely define the format of an audio souce so that all S/PDIF
audio outputs coax or optical are compatible with corresponding inputs?

If so then presumable DVB-S and DVB-T receivers that have S/PDIF ouputs must
do some sort of conversion from MP2 or AC3 and is this a loss less
conversion?

If I have an amplifier with a good quality DAC am I likely to get better
sound quality if I use an S/PDIF connection rather than a coax analogue
connection?
