Default i2s to parallel conversion

I need to handle a S/PDIF decoded stream (i2s from a Crystal decoder) in a Microchip PIC or AVR microcontroller and so thought a shift register with a little support logic could transform the serial i2s data to two sets of parallel data (16 bit - one set for each channel)and would free up a lot of time for the microcontroller. Has anyone done this or advise against this?
Thanks, Jeff

What is the sampling frequency that you plan to use? Maybe you could use another PIC (i.e. 16F877) dedicated to only the I2S.

Looked at dsPIC microcontrollers? you can get them with codec interfaces that can handle I2S input directly...

Thanks for the quick responses.

Sync40 - another PIC is what I have planned. The sampling rate will be 48KHz - 16Bit and so figured I would alot 4 addressable registers to hold these values and pass them parallel to the operating PIC.

gmarsh - I have not considered these - thanks. I am a bit leary of learning yet another system (software and hardware) but will if the application fits. Time to read the data sheets...
