Description

The AC3overDVB patch for VDR sends digital audio data in AC3 and DTS format to the digital S/PDIF port of the DVB card. Therewith VDR has the ability to output Dolby Digital as optical or electrical S/PDIF signal.

The digital S/PDIF port of the DVB cards is only capable of sending PCM data, so the AC3 data has to be encapsulated into a PCM stream. This digital audio data stream is then received and decoded by a external Dolby Digital receiver.

Hardware requirements

• DVB card with S/PDIF port
• compatible Dolby Digital receiver (see hint)

Software requirements

• patch

Applying the patch

If the patch is compressed you have to unpack it before

gunzip patch

Now you can install it with

cd $SOURCEDIR/VDR
patch -p 1 < /path/to/patch

Note, VDR has to be recompiled now, see VDR installation.
