– useful for planned maintenance on the primary programme channel. Like all MARBLE-V1 video processing software apps, the M-SAFESWITCH-2 and M- SAFESWITCH-2L can be used with IP (ST 2022 or ST 2110 video), with SDI or with both IP and SDI at the same time (thereby providing gateway functionality). - Page 6 Flexible remote control and monitoring using frame integrated control panel, VisionPanel remote control panel, ASCII and JSON protocols, SNMP and the web browser-based VisionWeb Control • Dual slot card allowing 10 cards in Vision 3 frame M-SAFESWITCH-2/2L User Manual R1.4 21 July 2022...

Page 8: Hardware Installation
The potentiometers on the card are factory set and should not be adjusted. There are no user-selectable links. The app based MARBLE-V1 cards are intended for use only in the Crystal Vision ‘Vision’ frame range and not in older style frames such as ‘Indigo’. -

IP address. It is, however, possible to use the same virtual interface for all input and output flows. If using SDI I/O with an analogue reference no virtual interfaces will need configuring. M-SAFESWITCH-2/2L User Manual R1.4 21 July 2022... - Page 10 Crystal Vision I/O Configuration In a fully IP environment, the following example shows how the M-SAFESWITCH-2/2L primary and protect input and output flows could be assigned to individual virtual interfaces. As previously mentioned, it is also possible to assign all flows to the same interface.

Page 11: Enabling Inputs & Outputs
I/O Configuration 4.2 Enabling Inputs & Outputs By default M-SAFESWITCH-2/2L inputs and outputs are disabled. Use the Enable control within the Input and Output menus to enable them. To prevent exceeding the network interface and processing bandwidth, 3G video inputs are supported on inputs 1 and 3 only. -
Page 12: Select I/O Protocol
I/O Configuration 4.3 Select I/O Protocol M-SAFESWITCH-2/2L supports SDI and uncompressed video over IP protocols ST 2022 and ST 2110-20. It is possible to mix protocols between input and outputs. For example, an ST 2022 input can be output as SDI on Output 1 and ST 2110 on Output 2. -

I/O Configuration 4.4 Receiving an IP Flow M-SAFESWITCH-2/2L receives ST 2022 or ST 2110-20 video over IP flows using the 10GbE network interfaces on the VR04/VR06/VR07 Vision frame rear connector. Typically Eth 1 is used for receiving and transmitting the ‘primary’ IP flows, with Eth 2 being used for the ‘protect’... -

I/O Configuration 4.5 Transmitting an IP Flow M-SAFESWITCH-2/2L transmits ST 2022 or ST 2110-20 video over IP flows using the 10GbE network interfaces on the VR04/VR06/VR07 Vision frame rear connector. Typically Eth 1 is used for receiving and transmitting the ‘primary’ IP flows, with Eth 2 being used for the ‘protect’... - Page 15 When transmitting ST 2110 the required payload type value should be set. The value for payload type is arbitrary and decided by the user. For example, value 100 could be used to indicate 1920x1080i 50Hz content and value 101 used to indicate 625i 50Hz content.

Page 20: Safe Switch Processing
Safe Switch Processing 6 Safe Switch Processing M-SAFESWITCH-2/2L features dual independent 2x1 switches. Source A to B switching can be triggered automatically based upon user configurable input fault conditions, or manually – useful for planned maintenance on the primary programme channel. -
Page 21: Auto Switch Configuration
The switch to Source B will occur regardless of whether or not the flow assigned to Source B contains errors. It is therefore recommended that all inputs are continuously monitored for errors, using SNMP for example. M-SAFESWITCH-2/2L User Manual R1.4 21 July 2022... -
Page 22: Audio Errors
The ‘Delay audio silent’ control allows audio to be silent for the set amount of time before triggering the switch. This is adjustable between 1 and 120 seconds and is a global setting which applies to both to switch 1 and 2. M-SAFESWITCH-2/2L User Manual R1.4 21 July 2022... -

Page 24: Output Routing
Safe Switch Processing 6.4 Output Routing M-SAFESWITCH-2/2L features dual independent 2x1 switches. There are three outputs. Outputs 1 and 2 out can be configured to be either IP or SDI. Output 3 is IP only. By default outputs 1 and 3 route to the processing from Switch 1. Output 2 routes to Switch 2. -

Page 26: References And Output Timing
Timing 8.1 References The M-SAFESWITCH-2/2L outputs can be locked to a PTP clock, an analogue tri-level or Black & Burst sync or the SDI input if present and selected as the flow in protocol. If the chosen reference sources are absent at power up, the outputs will freerun to an internally generated clock. -
