Features
The GIX170 and HIX170 are dual channel high performance 3Gb/s, HD and SD SDI video and
embedded audio probes (signal integrity monitor) with clean video switch-over function.
The switch function can be triggered by any of the integrity controls or by GPI. Besides the extensive
probe functions, the cards also provide full line and frame synchronization on both inputs.
An interesting feature is the ability to apply 4 individual sources and pre-route these signals to any
of the main channels. This enables a backup functionality beyond two channels and can be used for
adding a third or fourth backup channel.
The core capacity of the GIX/HIX170 is the ability to switch on SCTE104 triggers or the absence of
them as outlined below.

SCTE104 functionality
Introduction
The GIX/HIX170 will monitor the SCTE-104 signalling of an input video feed and switch between
video sources according to the card’s internal configuration.
The diagram below shows the logical design of the card.

There are two use cases for this card:


Blanking (switching away from) a video based on that video’s SCTE-104 signalling
Opting (switching towards) a video based on that video’s SCTE-104 signalling
These two use cases will be explained in the following sections.
The design of the card is such that both these use cases (and many more) can be configured via
Cortex into individual Presets.

Blanking
The intent of this use case is to temporarily replace a channel with an alternate video due to legal
or rights limitations.
Inputs:

Input A (relay protected): would carry the main programme, including a SCTE-104
blanking cue

Input B: would contain an alternate video stream

Expected Input
The GIX/HIX170 has 4 physical inputs that can be routed to two probing engines, referred to as
“Input A” and “Input B”.
The card will work in either SD or HD mode. Both inputs will be the same format. If they are not,
an alarm will be raised.
Either input (or both inputs) could include SCTE-104 signaling. The card will allow configuration to
select which video feed should be monitored for SCTE-104 signaling. Any signaling on the nonmonitored feed will be ignored.
SCTE-104 signaling
The trigger to monitor for switching video streams will be based on a configured selection of one of
BBC R&D White Paper 2961. The cues will be from “psp_flags_prog” as shown below:

Blanking Platform 1 (bit 4)

Blanking Platform 2 (bit 5)

Opt-Out (bit 11)

Reserved (bit 14)

Reserved (bit 15)
Expected Output
Output Video Signal
The card will output in the same format as received in the input video signal. At least 3 identical
HD/SDI outputs are provided. The first output will be protected by relay bypass from Input A when
using a BHX17.
The output video will be appropriate video feed as chosen via the SCTE signaling and card
configuration.
Output during a switch
All switching will be clean, seamless with no switching artefacts.
Switching will be ‘frame accurate’ relative to the SCTE signaling.
