1 Introduction
The TANDEM-110 (Twin ANalogue and Digital EMbedder/de-embedder) can be
configured with two piggyback option cards to provide two functions at once – embed
analogue or digital audio into SDI or de-embed analogue or digital audio from SDI. There
are two independent SDI signal paths and each SDI path contains, in addition to data
management processing, either a de-embedder or an embedder.
In addition to multi-mode dual embedding and de-embedding TANDEM-110
incorporates a number of powerful features. For example, adjustable audio gain and delay
is provided to compensate for video processing and system gain errors, analogue
monitoring can be used to preview sources and audio quality is ensured with sophisticated
error masking.
The main features are as follows:
dual embedder/de-embedder or mixed embedder/de-embedder
built-in dual multi-channel digital audio delay
adjustable audio channel gains
stereo to mono conversion
dual HANC processors for independent data packet management
audio source preview monitoring
optional SDI ‘TBC’
optional external AES or word clock reference input for digital output modules
optional EDH insertion on embedder and de-embedder
control/status monitoring via board edge, remote control panel and Statesman
buffered SDI and AES outputs
audio error masking and protection in de-embedders – handles untimed or
asynchronous upstream SDI switching with minimum corruption
GPI control of configuration set-ups
The option card position for side 1 is at the top of the module and the slot for side 2 is at
the bottom of the module.

An 18 volt regulator option card is also required for analogue input or output cards.
