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 Digital, DD+, DTS or

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

simultaneously.

•

Dolby Digital* mixing: this mode outputs both primary video sound and

secondary video sound simultaneously by mixing both audio and encodes into

a Dolby Digital bitstream. Select this option if your external decoder unit (AV

Receiver) supports Dolby Digital.

• 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.

Note: * this feature is not available in some versions of CyberLink PowerDVD.

HDMI Output Modes

computer.

• PCM decoded by PowerDVD: this mode creates a digital representation of an

analog signal. Select this option if your external decoder (AV receiver) does not

support Dolby Digital or DTS to produce a digital sounding output for your

audio.

• Non-decoded Dolby Digital/DTS audio to external device: this mode passes

compressed audio through to your external decoder (AV receiver). Select this
