INTRODUCTION
1 Redbox Audio Embedders & De-Embedders
The Redbox range of audio embedders and de-embedders use the latest
technology to offer embedding and de-embedding for analogue and digital audio
signals into and out of all 3G, HD and SD-SDI video signals, respectively. There
are currently 4 products in the range.
RB-VHDMA8 3G/HD/SD-SDI De-Embedder, 8 Channel Analogue Outputs
The RB-VHDMA8 is an 8 channel analogue de-embedder contained in a single 19-inch
rack unit. The unit can selectively de-embed up to 8 channels within any audio group of
an SDI video signal, to any of the analogue outputs. After which, the video becomes two
independent paths, where the audio groups can be selectively deleted or passed through
and then sent to the re-clocked SDI outputs.
The de-embedding channel routing is controlled via the front panel buttons and
indicators. There is also LED indication for SDI input status and audio group presence.
The unit can be remote controlled via Ethernet or serial port connections using the Sonifex
SCi software.
It has a triple rate SDI receiver with automatic input rate detection and equalisation along
with two re-clocked and individually buffered SDI outputs. It supports the full range of 3G,
HD and SD standards from NTSC and PAL up to 1080p 60Hz.
There is independent level control for each analogue output channel, which can be
adjusted from -24dB through to +24dB in 0.5dB steps.
The analogue outputs have three full-scale gain settings which can be set via jumpers
inside the unit. Allowable settings are +12dBu, +18dBu and +24dBu reference FSD. The
balanced and unbalanced output connections are paralleled, allowing one type to be used
per output.
RB-VHEMA8 3G/HD/SD-SDI Embedder, 8 Channel Analogue Inputs
The RB-VHEMA8 is an 8 channel analogue embedder contained in a single 19-inch rack
unit. The unit can selectively embed up to 8 analogue channels onto either of the two
output video paths which are sent to the re-clocked SDI outputs. It also has the capability
to allow audio groups to be deleted or passed through on each of the two video paths
prior to the embedding process.
The embedding channel routing is controlled via the front panel buttons and indicators.
There is also LED indication for SDI input status and audio group presence.
The unit can be remote controlled via Ethernet or serial port connections using the Sonifex
SCi software.
It has a triple rate SDI receiver with automatic input rate detection and equalisation along
with two re-clocked and individually buffered SDI outputs. It supports the full range of 3G,
SD and HD standards from NTSC and PAL up to 1080p 60Hz.
