Digital Out DVD SACD player , Does it pass HDCD?

Well I have two quick questions... One-Does the SACD DVD players have to play out the analog Jacks to pass thru the SACD Decoder, Which Kind of does not make sense considering it is a surround sound Format right? Also, I see many manufactures have the HDCD Chips built into the RECEIVERS (Eg.Harman Kardon) so Will it pass the HDCD signals off the disc thru the Digital outputs(Coax & opticle)To the receiver and Then decode with the DACS in the Receiver, I have heard HDCD will only work with the Players onboard chip and play out the Analog? This would not make sense Due To the Decoders being in some of the Receivers. Thanks.
