Angry SM5842 digital filter

To enhance a CD624 (Philips) I would like to build a new backend, that means: all behind the SAA7310 will be replaced by a digital filter and better DACs.
From the SAA7310 I get an I2S: left justified with one bit delay.
The table 7 in de doc of the SM5847AF (Nippon) digital filter as well as table 3 in the doc of the SM5842AP/APT does not give a for me understandable solution to transform to right justified for the PCM63 DAC's.

Please help me.

Systems that assume to know too much are more a hindrance than a help.
