Adding SPDIF input port to Sony DAV-DZ100

[i-dar]

[FONT=Arial,Bold][FONT=Arial,Bold]Hi, I am trying to add an SPDIF input port to my Sony DAV-DZ100 HTiB. I am using the information from service manual for Sony DAV-DZ820 as it utilizes the same receiver chip (LC890561W) and has two digital input ports. The schematic is in the attachement.[/FONT][/FONT]

[FONT=Arial,Bold][FONT=Arial,Bold]The question I would like to get your help on is why the signal from coaxial is inverted using SN74LVC1G04? Thanks!
