M-SAFESWITCH-2

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. There may be known and accepted upstream events which can occur in a system and therefore switch tolerance can be applied, where errors are permitted to occur for up to ten frames before the switch to Source B triggers.

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.

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. As well as a framestore synchroniser on each flow, it can delay the earliest arriving input by up to ten frames – while Source B can also be delayed by an additional 60 frames for when Source A is subjected to a long delay, such as from a graphics system.

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.

Traffic shaping

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. An additional 60 frames of delay (adjustable in one frame steps) is available to further delay Source B on each switch - useful for input timing alignment when there are long Source A delays, such as those created by a graphics system. 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.

Flexible control

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, VR06 or VR07 frame rear module is used to access the four inputs and three outputs on the M-SAFESWITCH-2 app. Two of the outputs are configurable as IP or SDI, while the third output is fixed as IP.

Flexible assignment of the flows allows you to get the configuration you need. With the default being two outputs of Switch 1 and one output of Switch 2, it is possible to configure the product to give two or three outputs of either Switch instead, if required.

Protect your SDI output - with relay bypass protection

The VR07 frame rear module provides dual relay bypass protection when the M-SAFESWITCH-2 is used with both SDI inputs and SDI outputs to help maintain programme output.

The relay bypass protection protects the video output on frame power failure or if the MARBLE-V1 card loses power or is removed. It prevents signal loss by mechanically connecting an SDI input to an SDI output. SDI In 1 is connected to SDI 1 Out and SDI In 2 is connected to SDI 2 Out.

The VR07 additionally includes four 10GbE network interface, making it easy to upgrade to IP when required – with the resilience then provided by IP best practice.

Weight: 355g

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)

SDI VIDEO INPUTS

(NB. Some or all of the inputs can be IP instead)

Up to two 3Gb/s SDI inputs or four HD or SD SDI inputs. If the input is 3Gb/s then Input 1 and Input 3 should be used

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. Some or all of the inputs can be SDI instead)

Up to two 3Gb/s video over IP inputs or four HD or SD video over IP inputs. If the input is 3Gb/s then Flow input 1 and Flow input 3 should be used

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. Some or all of the outputs can be IP instead)

Up to two 3Gb/s or HD or SD SDI outputs (NB. Two 3Gb/s outputs available when both are routed to the switch with 3Gb/s inputs)

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. Up to two of the outputs can be SDI instead)

Up to three 3Gb/s or HD or SD video over IP outputs (NB. Three 3Gb/s video over IP outputs available when all are routed to the switch with 3Gb/s inputs)

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

RELAY BYPASS PROTECTION (SDI ONLY)

The VR07 frame rear module provides dual relay bypass protection when M-SAFESWITCH-2 is used with both SDI inputs and SDI outputs

The relay bypass protection protects the video output on frame power failure or if the MARBLE-V1 card loses power or is removed

An electromechanical relay switch on the VR07 needs power to hold the switch in one state and will revert to the other state (card bypass) on loss of power. It prevents signal loss by mechanically connecting an SDI input to an SDI output: SDI In 1 is connected to SDI 1 Out and SDI In 2 is connected to SDI 2 Out

NB. Use of the VR07 requires issue 5 or later of MARBLE-V1

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)

IP PROTOCOLS

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 ten frames between the input flows. Additional delay of up to 60 frames can be applied to Source B of each switch, should the Source A delay be greater than the ten frames adjustment provided at the flow input stage

AUTO SWITCH PARAMETERS

M-SAFESWITCH-2 performs checks on the following ten 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. Switch tolerance can be applied which allows the error to exist for up to ten frames before the auto switch will occur

• Input not present
• Incorrect input format
• Video black
• Video frozen
• Video error
• Network error
• Audio group 1 missing
• Audio group 2 missing
• Audio group 3 missing
• Audio group 4 missing

In addition to the ten frames switch tolerance, detection delay can be applied to the video black and video frozen auto switch parameters which allows the picture to remain black or frozen between 1 and 120 seconds before the auto switch will occur. Black and frozen delays can be individually set, but each is common to both switches
Black is detected when all pixels are black – a single non-black pixel resets the detection delay period
Frozen is detected by splitting each video frame into a grid of image tiles where the sum of pixel values within each tile is computed and compared against the previous frame. If the difference between sums is greater than the in-built frozen detection threshold, the image is detected as not frozen and this resets the detection delay period. This allows frozen video to be detected even in the presence of noise or ‘bad’ pixels

ROUTING

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 Flow output 3 and Switch 2 to Flow output 2. The default inputs to Switch 1 are Flow input 1 and Flow input 3. The default inputs to Switch 2 are Flow input 2 and Flow input 4

It is also possible to configure the product to give two or three outputs of Switch 1 or Switch 2 instead, if required (NB. Third output only available in IP)

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

TEST PATTERNS

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 outputs

There 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>Ref1>Ref2>Hold
• PTP>Ref1>Hold
• PTP>Ref2>Ref1>Hold
• PTP>Ref2>Hold
• PTP>Hold
• PTP>Ref1>Ref2>SDI>Hold
• PTP>Ref1>SDI>Hold
• PTP>Ref2>Ref1>SDI>Hold
• PTP>Ref2>SDI>Hold
• PTP>SDI>Hold

(“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

Additional 60 frames of delay (adjustable in one frame steps) is available to further delay Source B on each switch. This is useful for input timing alignment when there are long Source A delays, such as those created by a graphics system

Ten frames of flow output video delay (adjustable in one frame steps) allows compensation for any big system delays

ANCILLARY DATA

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:

Power okay

PRESETS

The current app settings can be saved in one of 16 locations to be recalled as required

SIGNAL MONITORING

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
