QuadSync Mode
The Sapphire Codec system features innovative QuadSync technology allowing up to four HD inputs
to be seamlessly switched into a single stream. The perfect accompaniment to Sapphire Ultra-low
latency HEVC encoding, QuadSync introduces no more than a single frame of additional delay.
On an encoder with QuadSync not only can the four sources be asynchronous, but they can also be a
variety of different, automatically detected HD-SDI and 3G-SDI formats. This removes the need for
external frame resynchronisers or standards conversion and enables a more flexible choice of camera
for multi-view applications. The four sources can be selected using either IP or RS-232 control.
On the decoder with QuadSync you gain the option of converting again without the need for external
frame resynchronisers or standards conversion.
Simple but flexible audio routing is available. Either take up to 4 pairs of audio from the first SDI input,
or 1 pair of audio for each SDI input. All audio sources will remain active even when sourced from an
unselected SDI input.
The easiest way to enable QuadSync is using the Video Helper on the Web browser Config Video page
shown below. To enable QuadSync select 4 x HD and the appropriate video frame rate on the Video
Helper. This will automatically select the correct parameters for QuadSync.
