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.
Not all DD receiver are capable of decoding an encapsulated pcm stream.
- DVB card with S/PDIF port
- compatible Dolby Digital receiver (see hint)
