Mode 4
Mode 4 is designed to allow embedded audio to be replaced from an external source. Both
SDI circuits share half of one input module and half of one output module.
Mode 4 is be referred to as ‘audio break-out and embed’. Background audio of a sports
event can be monitored on two channels (de-embed) and commentary added on the other
two channels (embed). This operation can be performed for two embedded SDI inputs.
TANDEM-200 in Mode 4
Mode 4 provides the following functions:
•
dual stereo replace embedders
•
embedded audio can be replaced from external stereo audio source
•
stereo audio output from each SDI channel for monitoring incoming feed
Note:
The option card on side 1 must be an issue ‘B’ input board and side 2 must have an issue
‘B’ output board. The card-edge BFormat test detailed in section 9.14 will test for board
issue type.
There is one delay module available on each side, this means that delay can be assigned
to an output router or an embed router but not to both.
