I have a question about digital music channels for anyone who can answer- I listen to Music Choice channels on my cable box (hooked up to my receiver via HDMI) and the receiver recognizes them as Dolby Digital 2.0. I am curious whether this is a very lossy encoding of the music, or if it is true CD quality audio? Seems unlikely that it would be decoded to the same quality as the PCM on a CD. I searched the net for an explanation of the bitrate afforded each channel in a dolby digital 2.0 stream, and to try to find out if it decodes to the same quality as CD audio, to no avail. Can anyone shed some light?
