S/PDIF Output Modes

The following output modes are available during the playback of Blu-

ray Disc titles when S/PDIF is selected as the speaker environment. The

mode that you should select depends on the external decoder (AV

Receiver) connected to your computer.

• Only primary audio: this mode only outputs the audio from the

primary video (e.g. no sound will be available for Picture-in-

Picture, secondary video streams or director commentaries). The

compressed audio format is passed-through to the external

decoder unit (AV Receiver).

Note: If the primary audio format is another format besides Dolby AC3, DD+,

DTS or DTS-HD, CyberLink PowerDVD will decode it and output both audio

signals simultaneously.

• AC3 mixing: this mode outputs both primary video sound and

secondary video sound simultaneously by mixing both audio

and encodes into a Dolby AC3 bitstream. Select this option if

your external decoder unit (AV Receiver) supports Dolby AC3.

• DTS mixing: this mode outputs both primary video sound and

secondary video sound simultaneously by mixing both audio

and encodes into a DTS bitstream. Select this option if your

external decoder unit (AV Receiver) supports DTS.

HDMI Output Modes

The following output modes are available when an external decoder

(AV Receiver) is connected with an HDMI connector. The mode that you

should select depends on the external decoder (AV Receiver)

connected to your computer.

• PCM output: this mode creates a digital representation of an

analog signal. Select this option if your external decoder (AV

Receiver) does not support AC3 or DTS to produce a digital

sounding output for your audio.

• AC3/DTS pass-through: this mode passes compressed audio

through to your external decoder (AV Receiver). Select this

option if your amplifier/receiver supports AC3 or DTS to enable

Dolby Digital or DTS audio during playback, when available.
