User Manual
From a deployment perspective, it is recommended that 8/8 builds are favored for
1080p59. Whilst the IP core does not impose any limitations on the end user as to which
signals are sent/received from which spigot, there are three important limitations that
otherwise need to be taken into account when deploying a system:
1 You must ensure that the bandwidth of the media interface is not exceeded. For
example, if the 0/16 configuration of a IQUCP25 was used with 16 unique 1080p50
ST2110 - 20 ST2022 - 7 streams, this would clearly exceed the 25GbE data rate of the
media interface, and so would subsequently fail.
2 PLUS, if the card is in Make-Before-Break mode, then for every simultaneous change
the stream count is 2, not 1, for duration of the change.
3 PLUS, there is an IP Receiver hardware limitation on the IQUCP25 and IQUCP50 as to the
number of streams that can be processed concurrently. This is captured in the table
below.
Use Case 5
4 ×
SD/HD/3G
1 × ST2110 In this use case, a UHD signal is
represented by 4 × 3G - SDI
(ST425 - 5), and results in a single
ST2110 - 20 flow. The
master/slave behavior is still
adopted, with Link 1 being the
master. This behavior is
controlled by the Link page; see
Link Control on page 110.
