channels.

 

The SDI/HDSDI/3G SDI video transport

supports up to 16 audio channels, arranged in four groups of four channels each.

Transport Mode (Ç)

The VN-Matrix system supports two audio transport modes:

Transparent — The compression engine streams the selected audio data

exactly as embedded in the SDI/HDSDI/3G SDI format, with no processing. This mode can result in a high bit rate.

Stereo — The compression engine extracts a single stereo pair (two channels) of audio data and packs it into the data stream.

Channel pair selection (É)

Channel pair 1 — Selects group 1, channels 1 and 2. Channel pair 2 — Selects group 1, channels 3 and 4.

Channel pair 3 — Selects group 2, channels 1 and 2. Channel pair 4 — Selects group 2, channels 3 and 4. Channel pair 5 — Selects group 3, channels 1 and 2. Channel pair 6 — Selects group 3, channels 3 and 4. Channel pair 7 — Selects group 4, channels 1 and 2 Channel pair 8 — Selects group 4, channels 3 and 4.

In Transparent mode, you can select from two to eight channel pairs; you cannot select a single pair. In stereo mode, you can select only one channel pair.

The indicator to the right of the list showing each channel pair is green if that audio group is present in the SDI source.

Compression (Î)

 

NOTE:

The compression drop box is available only when the stereo

 

 

transport mode is selected.
