SDI cards
The SDI card for DB4/DB8 supports all commonly used SD and HD formats. While de-embedding and embedding 8
channels of audio (48 kHz, 24 bit), selectable from the four SDI Groups in chunks of four audio channels, it passes the
video side untouched.
Processing may be inserted on any two of the four SDI Groups, and re-embedding may take place on any two groups.
Consequently, the machine enables cross patching of audio and format conversion between SDI Groups. The design
features two separate SDI inputs, of which one is active at a time, and two parallel, separately buffered outputs.
The DB’s present an attractive SDI solution with massive jitter rejection, 48 bit processing and low latency. They also
feature bit transparent, synchronous data handling, enabling routing of data reduced audio, such as AAC, DTS or Dolby E.
DSP6000 SDI I/O6000 SDI HD
HD Audio
• Embedded audio multiplexer and demultiplexer
• Supports 38 HD video formats
• Supports eight audio channels at one time
• Fully SMPTE 299M compliant & compatible with common
non-compliances
• Up to eight bit errors can be corrected in each audio data
packet
• Full support for 48 kHz synchronous or asynchronous
16-bit, 20-bit and 24-bit audio
• All four audio groups can be deleted
• Any two audio groups can be replaced when operating in
multiplexer mode
SD Audio
• Embedded audio multiplexer and demultiplexer
• Supports 6 SD video formats
• Supports eight audio channels at one time
• Compliant to SMPTE 272M A and C & compatible with
common non-compliances
• Full support for 48 kHz synchronous 16-bit, 20-bit and
24-bit audio
• Programmable audio sample distribution
• All four audio groups can be deleted
• Any two audio groups can be replaced when operating in
multiplexer mode
Automatic Bypass
The DSP6000 SDI card (bypass version) features automatic
bypass at power-down or at loss of power. Even at boot-up
audio and video is passed lossless to transmission.
SDI I/O Expansion card
• With the SDI expansion card installed up to 16 I/O
channels can be handled either in 1 TV stream with 16
channels or in 2 TV streams with 8 channels each.
Technical notes
Max recommended cable length is 60 meters to and from
DB8/DB4. Cable type should comply to SMPTE standards,
such as Belden 1694 or better.
Note that in bypassed mode the total cable length pre AND
post the unit should not exceed 60 meters.
When an installation is finished, please check bypass
functionality by turning off the DB processor in situ to take
cable types and cables lengths into account.
