ESAI or S/PDIF for SPDIF stream

Greetings,

 

I have a question with the S/PDIF usage in I.MX6 processors. I know there is an S/PDIF  and also ESAI (Enhanced Serial Audio Interface) in I.MX6.

ESAI is compatible with SPDIF transceivers but the processor already has a module for SPDIF transmitter and receiver.

 

My question is, is SPDIF interface actually a part of ESAI (which I assume not) or is it a seperate interface? If they are seperate interaces, which would you suggest

using for streaming 5.1/7.1 audio or stereo sound? I assume that using the ESAI and an extra transceiver will reduce the burden on the processor while increasing

the cost, but does it also increasing the programming work, is ALAS okay with me using ESAI for SPDIF or do I need to come up with a driver for that? Or would you

just suggest me using the SPDIF interface for its designated purpose.

 

I have to note that asides from acting as an audio streamer, the proposed system might also be streaming HD vidoe through HDMI and performing other network control

bussiness in the meanwhile so the processor will be quite busy.

 

Thanks in advance,

Mete
