What is it?
Dual channel IP/SDI 2 x 1 fail-safe routing switch app.
Reason to choose it...
You'll get no disruption to the output picture when a switch takes place. It will correct for any timing difference between the two inputs, thanks to the framestore synchroniser plus the ability to delay the earliest arriving input by up to ten frames. You can select from ten fault conditions to automatically trigger a switch, or you can switch it manually. The fact you can use it with IP, SDI or both makes it perfect for any installation – including giving you the easiest upgrade to IP. It's dual channel to save you money. Plus it's future-proof – when this functionality is no longer required you can get a different app for your MARBLE-V1 hardware.
You need a switch you can rely on to always give you a disruption-free output in your IP or SDI installation – whether for your planned maintenance switches, or as a very sophisticated auto changeover switch where you want to specify the fault conditions that will auto-trigger the switch.
Try out the M-SAFESWITCH-2 VisionWeb GUI (opens in new window) – you'll see how easy it is to operate the M-SAFESWITCH-2 app from your web browser, while exploring the full functionality of the product.

The way to guarantee a clean switch
The dual channel M-SAFESWITCH-2 provides two independent 2 x 1 clean switches. It can be switched either manually or automatically – making it ideal for planned maintenance switches to manually re-route a good signal around broken equipment, or for use as a very sophisticated auto changeover switch, with the option of selecting from ten different fault conditions to automatically trigger the switch.
The M-SAFESWITCH-2 uses source A as its primary input and source B as its secondary input, and will only auto switch to source B if any of the user-defined faults occur on the primary source A.
After switching away from a faulty input, the M-SAFESWITCH-2 can be set to switch back automatically or by user intervention.
The ten fault conditions that can be selected to automatically trigger a switch are input missing, input video standard incorrect, active video black, active video frozen, video error, network error, audio group 1 missing, audio group 2 missing, audio group 3 missing and audio group 4 missing. Different parameters can be chosen for each switch.
The app's helpful status monitoring will indicate which errors are present for each flow, allowing them to be fixed before switching back.
The M-SAFESWITCH-2 will guarantee a clean switch and is ideal for use on the final output stage of a transmission system, before the signal gets to the MPEG encoder. Typically the backup signal going into the switch will have gone a simplified route compared to the main programme, resulting in a time difference between the two feeds which can upset the MPEG encoder on a switch to backup.
With a framestore synchroniser on each flow plus the ability to delay the earliest arriving input by up to ten frames, the M-SAFESWITCH-2 can correct for any timing difference between the two inputs – resulting in no disruption to the output picture when a switch takes place. Further protection comes from the user-defined timing source priority for redundancy, with the option of selecting from the two analogue references on the Vision 3 frame as well as PTP master and backup signals. Should the main syncs become invalid, it will automatically switch to the specified backup syncs.
Use it with IP, SDI or both
The M-SAFESWITCH-2 can be used with IP, with SDI or with both IP and SDI at the same time. Its support for multiple signal formats gives the easiest possible SDI to IP upgrade, while also making it perfect for mixed SDI and IP installations as well as fully IP or fully SDI environments.
It supports both SMPTE ST 2022 and ST 2110 video over 10GbE IP networks, including ST 2022-7 redundant streaming and the protect equivalent for ST 2110.
The IP flows can be separated and protected across up to four bi-directional 10GbE SFP+ network interfaces. There is a choice of fibre modules for the fibre SFP+ 10GbE IP network interfaces: either 850nm multi-mode for up to 300m or 1310nm single-mode for up to 10km.
When used with SDI or SMPTE ST 2022, the M-SAFESWITCH-2 passes all ancillary data including embedded audio without modification. If ST 2110 is used, only the video content is output.
Other features include full VLAN support with no restrictions and unicast and multicast transmission support.
It's a software app
The future-proof M-SAFESWITCH-2 is a software app that runs on the MARBLE-V1 media processor – purpose-built GPU/CPU hardware that fits in the Vision frames.
Apps that are bought with the hardware can be replaced with different apps as needs change, helping you make the most of your budget.
More about MARBLE-V1
Featuring a powerful CPU/GPU processor, the MARBLE-V1 media processor hardware has six bi-directional SDI connections and four 10GbE SFP+ network interface ports (as well as eight bi-directional discrete AES stereo channels for future products).
The software app installed determines the functionality.
IP gateway and translation functionality included
The M-SAFESWITCH-2's gateway functionality can be used to integrate SDI into an IP environment or IP into an SDI environment.
Its IP to IP translation functionality can be used for network address translation, protocol conversion (between any of the input formats and any of the output formats), unicast to multicast address conversion and the creation of media firewalls.
With the potential for networks and IP receivers to not be very tolerant to bursty traffic, the M-SAFESWITCH-2 will ensure a nicely constructed IP output (with a choice of traffic shaping options), while its tolerant IP inputs are designed to be robust to bursty traffic.
Choice of timing sources
The M-M-SAFESWITCH-2 includes a framestore synchroniser timed to an external Black and Burst or tri-level syncs analogue reference or PTP.
The chosen reference is the global reference source for all input and output flows.
Reference redundancy offers peace of mind in case the main reference source is disrupted or needs to be taken down for maintenance, while cross-locking allows for mixed reference type and format installations if required.
There are up to ten options for the reference selection, selectable via VisionWeb. (See the Specification for full details.) Should the timing source at the top of the list become missing or invalid, the card will move down the list until it finds a valid timing reference source.
The output timing can be fully adjusted with respect to the chosen reference using three time-based controls (0 - 42ms adjustable in 0.1ms steps, 0 - 100us adjustable in 1us steps and 0 - 1us adjustable in 5ns steps), with the selected timing alignment global to all output flows.
Ten frames of flow input video delay (adjustable in one frames steps) allows delay compensation between the two inputs sources to each switch, while ten frames of flow output video delay allows compensation for any big system delays.
Monitoring your signals
Features are provided to speed up system trouble shooting, particularly helpful with IP being more challenging to debug than SDI. Comprehensive SDI, IP and PTP monitoring information is available and can be used to generate SNMP traps.
The status indications available are video present and time present, video format, video black, video frozen, video error, Reference 1 and 2 present and time present, Reference 1 and 2 format, PTP master and backup clock present and time present and audio groups present. The video black and video frozen alert can be delayed by up to 120 seconds to prevent false alarming during brief video pauses.
PTP presence and statistics (network delay, delay variation, reference offset and sync period) are monitored.
The IP flow monitoring includes network error, packet loss, duplicated packets, packet delay variation, Ethernet interface ignored packets and Ethernet interface ignored multicast.
13 built-in test patterns can also help with fault finding.
All control is done remotely, with a choice of remote control and monitoring options for the M-SAFESWITCH-2 app running on the MARBLE-V1 media processor.
Hardware control options include an integrated control panel on the Vision 3 frame, the VisionPanel remote control panel and the SBB-4 smart button box.
Software control options include SNMP, our ASCII and JSON protocols and the VisionWeb web browser control. Try the M-SAFESWITCH-2 VisionWeb demo...
16 presets can be assigned and recalled.
Save rack space
Fitting in the standard Vision frames (currently available in 3U size), MARBLE-V1 is a space-saving 96mm x 325mm card that sits in one frame slot – allowing up to ten media processors in 3U. The double slot VR04 or VR06 frame rear module is used to access the four inputs and two outputs on the M-SAFESWITCH-2 app.
Flexible assignment of the flows allows you to get the configuration you need. With the default being one output per switch, it is possible to configure the product to give two outputs of Switch 1 or Switch 2 instead, if required.

‘Double slot’ Vision card 96mm x 303mm (96mm x 325mm including finger pull)
Power consumption: 25 Watts, plus 1 Watt for each SFP+ fitted to MARBLE-V1
INPUTS AND OUTPUTS
Inputs can be IP and/or SDI
Outputs can be IP and/or SDI
Six BNCs for SDI and up to four fibre SFP+ 10GbE IP network interfaces. Choice of fibre modules: either 850nm multi-mode (for up to 300m) or 1310nm single-mode (for up to 10km)
Inputs and outputs can be mixture of ST 2022 and ST 2110. Video can be passed between ST 2022 and ST 2110, although audio and any other non-video data will be lost
IP only, SDI to IP and IP to SDI applications require at least one SFP+ transceiver option, up to a maximum of four. Use one SFP+ to put all signals together, use two SFP+ to have main and protect or multicast and unicast on separate network interfaces and use three or four SFP+ to further separate flows
SDI only applications do not require any SFP+
Uses VR04 or VR06 frame rear modules. VR04 must be used when more than two SFP+ are fitted
SDI VIDEO INPUTS
(NB. Inputs can be IP instead)
Up to four 3Gb/s or HD or SD SDI inputs
270Mb/s or 1.5Gb/s or 3Gb/s serial compliant to SMPTE 259, SMPTE 292-1 and SMPTE 424/425-A
3Gb/s cable equalisation up to 100m using Belden 1694A. HD cable equalisation up to 140m with Belden 1694A or equivalent (approx. 100m with Belden 8281). SD cable equalisation >250m Belden 8281 or equivalent
IP FLOW INPUTS
(NB. Inputs can be SDI instead)
Up to four 3Gb/s or HD or SD video over IP inputs
Packet distribution is not important as variable input buffer will compensate for any timing irregularities. Any traffic shaping option from ST 2110-21 can be used, or packets can come from a device which does not meet the shaping requirement of ST 2110-21
A protect input for SMPTE ST 2022-7 seamless protection switching or the equivalent protect input in ST 2110-20 can come from any of the 10GbE IP network interfaces. This protects the stream from lost packets by creating two streams of the same data using different routing to the destination. Flow analyser handles the analysis and reconstruction of the protected stream. Any IP input can come from any of the 10GbE IP network interfaces and can either be multicast or unicast
SDI VIDEO OUTPUTS
(NB. Outputs can be IP instead)
Up to two 3Gb/s or HD or SD SDI outputs
270Mb/s or 1.5Gb/s or 3Gb/s serial compliant to SMPTE 259, SMPTE 292-1 and SMPTE 424/425-A
IP FLOW OUTPUTS
(NB. Outputs can be SDI instead)
Up to two 3Gb/s or HD or SD video over IP outputs
Any of the 10GbE IP network interfaces can be used to provide a protected output for SMPTE ST 2022-7 or ST 2110 seamless protection switching, which protects the stream from lost packets by creating two streams of the same data using different routing to the destination
Alternatively it is possible to have a unicast on some network interfaces and a multicast on others
VIDEO FORMATS SUPPORTED
The video formats supported are 625i, 525i, 720p50, 720p59.94, 720p60, 1080i50, 1080i59.94, 1080i60, 1080p23.98, 1080p24, 1080p25, 1080p29.97, 1080p30, 1080p50, 1080p59.94, 1080p60, 1080PsF23.98, 1080PsF24, 1080PsF25, 1080PsF29.97, 1080PsF30, 2048x1080p23.98*, 2048x1080p24*, 2048x1080p25*, 2048x1080p29.97*, 2048x1080p30*, 2048x1080PsF23.98*, 2048x1080PsF24*, 2048x1080PsF25*, 2048x1080PsF29.97*, 2048x1080PsF30* (*= YUV 4:2:2 10 bit)
Protocols supported on network interfaces: SMPTE ST 2022-6, SMPTE ST 2022-7, SMPTE ST 2110-20 (uncompressed video), SMPTE ST 2110-10 (system architecture and synchronisation), SMPTE ST 2110-21 (traffic shaping), IGMPv3, ARP, ICMP ping, IPv4, IEEE802.1q, VLAN, IEEE802.3-2012 (10G Ethernet)
Packing options of the ST 2110 output are selectable per flow between BPM and GPM (Block Packing Mode or General Packing Mode)
Packet shaping and distribution (compulsory in ST 2110 and optional in ST 2022) is selectable per flow between TPNL and TPN (narrow linear or narrow gapped packet distribution). There is also a mode for burst packet distribution with a control for the burst rate limit. This is for connecting between Crystal Vision and other compatible devices that allow for a reduced transmission delay
SMPTE ST 2022-7 and ST 2110 flow protection facilitates the dual stream output
MANUAL AND AUTOMATIC SWITCHING
M-SAFESWITCH-2 provides two 2 x 1 clean switches
These can be switched either manually (using the Switch to A and Switch to B buttons) or automatically
In auto mode M-SAFESWITCH-2 will always want to be on its primary input (Source A), only switching to secondary input B if there are user-defined faults on the primary input. It is possible to select from ten different parameters to automatically trigger the switch (see AUTO SWITCH PARAMETERS)
After switching away from a faulty input, M-SAFESWITCH-2 can be set to switch back automatically or by user intervention
When the Restore to A mode is set to "Delayed", M-SAFESWITCH-2 will automatically return to Source A once it has been clear of the monitored faults for the time set on the Restore delay slider, with the time programmable between two and 60 seconds
When the Restore to A mode is set to "Latched", M-SAFESWITCH-2 will stay switched to Source B until the user manually restores it to Source A
The framestore synchroniser in each input stream will ensure that both inputs to the switch are correctly timed to the reference so that there is no disruption during a switch
M-SAFESWITCH-2 can cope with signal path delays of +/-10 frames between Source A and Source B. Input timing differences greater than one frame can be corrected by delaying the earliest arriving input by up to ten frames in one frame steps
AUTO SWITCH PARAMETERS
M-SAFESWITCH-2 performs checks on the following parameters which can trigger an automatic switch, with the user able to select a number of parameters in any combination. Different parameters can be chosen for each switch
- Input not present
- Incorrect input format
- Video black. The period of time for which the picture must remain black can be set from 2 to 120 seconds (this setting is global to both switches). The entire active picture must be continuously black for the full period – a single non-black sample restarts the delay period
- Video frozen. The period of time for which the picture must remain frozen can be set from 2 to 120 seconds (this setting is global to both switches). The entire active picture must be continuously frozen for the full period – a single non-frozen frame restarts the delay period
- Video error
- Network error
- Audio group 1 missing
- Audio group 2 missing
- Audio group 3 missing
- Audio group 4 missing
The two clean switches can each select between the four input flows for their Source A and Source B
The default setting – which gives a dual channel 2 x 1 safe switch – is Switch 1 to Flow output 1 and Switch 2 to Flow output 2. The defaults inputs to Switch 1 are Flow input 1 and Flow input 2. The default inputs to Switch 2 are Flow input 3 and Flow input 4
It is also possible to configure the product to give two outputs of Switch 1 or Switch 2 instead, if required
VIDEO LOSS CONTROLS
The video loss controls allow the user to select what will happen to an output flow in the event that the input is lost. The user can specify to freeze the last good frame or show a black or blue screen or 100% colour bars (with or without an initial delay of three seconds). No output can also be selected. This is independently adjustable on each flow
The test pattern controls allow the user to override an input and force the output flow to output a test pattern including Colour Bars, Blue, Black, EqCheck, PllCheck, Pluge, Checkfield, Grey Horizontal Steps, Grey Vertical Steps, Luma Horizontal Ramp, Luma Vertical Ramp, Cycle Colour or Checker Board, or to freeze the picture. This is independently adjustable on each flow
SYNCHRONISER AND TIMING ADJUSTMENTS
Video sources are synchronised to common reference timing source
Choice of timing options:
- PTP (SMPTE ST 2059-2) master and backup, via 10GbE IP network interface
- Two tri-level syncs or analogue Black and Burst references (Reference 1 and Reference 2), connected via the Vision 3 frame
- SDI video input, where available (defaults to SDI 1)
Chosen reference is the global reference source for all inputs and outputsThere are up to ten options for the reference selection, selectable via VisionWeb. The hierarchy runs from left to right – should the timing source at the top of the list become missing or invalid, the app will move down the list until it finds a valid timing reference source. When used with IP inputs, the SDI reference option is not applicable and therefore the reference will move to the next valid timing source:
(“PTP” means PTP Master>PTP Backup. “SDI” means SDI1>SDI2>SDI3>SDI4>SDI5>SDI6, depending on number of SDI available. "Hold" means it will hold the timing of the last good reference)
When using video reference, video inputs can be different formats but only inputs with the same frame rate as reference video will be locked to that reference. Input signals of same frame rate as reference will be locked together and locked to external reference. Inputs with a differing frame rate will be locked and maintain timing with no drift, but their sync point will be undefined (all same frame rate signals will, however, be locked to each other)
When using PTP reference, input sources of different format and/or frame rate will all be correctly locked to the PTP reference
PTP timing reference should be used when there is a ST 2110-20 output to ensure the RTP timestamp is related to the time of day. However without a PTP reference, a valid ST 2110-20 signal will still be generated using a free running RTP timestamp
When Auto relock enable is selected, the card will automatically relock when a lost reference is restored. Selecting Force lock (with Auto relock disabled) will force the synchroniser to relock after a reference is restored, and can be activated at a non-critical time to avoid video disturbance
Output timing can be fully adjusted with respect to the reference using three time-based controls: 0 - 42ms adjustable in 0.1ms steps, 0 - 100us adjustable in 1us steps and 0 - 1us adjustable in 5ns steps. Sub frame timing alignment to chosen reference is global to all outputs
Ten frames of flow input video delay (adjustable in one frames steps) allows delay compensation between the two inputs sources to each switch
Ten frames of flow output video delay (adjustable in one frame steps) allows compensation for any big system delays
All ancillary data (including audio) is passed from SDI or ST 2022 input to SDI or ST 2022 output. When ST 2110 input or output is selected, all ancillary data is discarded
LED INDICATION OF:
The current app settings can be saved in one of 16 locations to be recalled as required
Comprehensive SDI, IP and PTP monitoring information is available and can be used to generate SNMP traps
Checks can be performed on the following video and audio parameters:
- Video present and time present
- Video format
- Video black
- Video frozen
- Video error
- Audio group 1 present
- Audio group 2 present
- Audio group 3 present
- Audio group 4 present
Black or frozen video will be indicated by an amber LED. This alert can be delayed by 1-120 seconds to prevent false warnings during brief video pauses
The following IP parameters are monitored for input flows:
- Network error
- Packet loss
- Duplicated packets
- Packet delay variation. Shown as the skew (difference in time of packet arrival) between the main and protected input, and also as the min and max nano second gap between the packets on each input
The Ethernet interfaces are monitored for:
- Count of packets ignored by the app (general network traffic non-media packets, which do not require processing by the app). Jumps in 100 step increments indicate network traffic flood
- Ignored multicast packets. LED indicates multicast traffic not requested by the app is present on the Ethernet Interface, indicating incorrectly configured IGMP at the network switch
References are monitored for:
- Reference 1 and 2 present and time present
- Reference 1 and 2 format
- PTP master and backup clock present and time present
- PTP statistics – network delay, delay variation, reference offset and sync period
