Example 2. Here the Quad-Speed audio ADD-ON bus shows a transmission application, where a dual
up/down/cross output card is connected to a DIO88 in a setup where the embedded audio combined
with external audio and convenient PCM monitoring is available.
Example 3. (illustrated below) A 4-card application can perform a massive amount of processing,
divided over 1 MASTER-CARD and 3 ADD-ON cards. This is a typical ‘ingest’ configuration and is used
where the infrastructure does not use Dolby E (two in this example) but PCM+s2020. The input is a SD,
HD or 3Gb/s SDI containing 2 Dolby E streams and 8 mono PCM streams. The output is the same SDI
stream but with a selection of 16 channels selected out 8 original PCM channels and 16 PCM channels
that are decoded from the Dolby E streams. The combo performs the following processing:
• De-embedding of 8x PCM and 2x Dolby E
• Decoding of two independent Dolby E streams
• Loudness processing of up to 16 channels sourced by any of the 8x PCM or decoded Dolby E
streams
• Upmixing of a 2.0 to 5.1 if a Dolby E stream is not available
• Physical monitoring of all processed PCM streams
• Preset based shuffling of all source channels into 16 channels with the appropriate offset delays
• S2020 metadata insertion sourced from the E decoders, embedded s2020, generated presets or an
external feed
• Video delay to compensate for audio propagation delay
• Embedding of up to 16 channels.
