Safe Switch 3G
What is it?
3G/HD/SD intelligent and clean 2 x 2 fail-safe routing switch.
Reason to choose it...
Because it's the only way to really guarantee a clean switch – always protecting the output and keeping the MPEG encoder happy. With a full framestore synchroniser on each input (plus the ability to delay the earliest arriving input by up to 25 frames), it can correct for any timing different between the two inputs – resulting in no disruption to the output picture when a switch takes place, even if you lose your reference. It will choose the best input to use (select from 18 different video and audio fault conditions) and it includes relay bypass protection.
You need a 2 x 2 switch you can rely on to give you a disruption-free output at all times – 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. See who's using it.

The way to guarantee a clean switch
Safe Switch 3G is the way to guarantee a clean switch – and protect your output.
It provides clean and intelligent 2 x 2 switching between two 3Gb/s, HD or SD sources containing up to four groups of embedded audio, with the full framestore synchroniser on each input allowing it to correct for any timing difference (big or small) between the two inputs – resulting in no disruption to the output picture when a switch takes place.
Ideal for planned maintenance switches to manually re-route a good signal around broken equipment, it can also be used as an intelligent auto changeover switch for those emergency transmission situations by engineers who do not want to restrict themselves to timed inputs, with the option of selecting from 18 different fault conditions to automatically trigger the switch.
With the ability to deal with any type of timing issues, Safe Switch 3G gives you a clean switch that can survive even the most catastrophic failure. It can even lose the reference signal and not affect the output. Your viewers will never know there’s a problem.
Why do you need a clean switch?
Continuity of service is vital and it’s crucial you don’t go off air. This is why Safe Switch 3G is ideal for use on the final output stage of a transmission system, before the signal gets to the MPEG encoder.
Typically the main programme path goes through various ‘boxes’ before going into a 2 x 1 switch. The second input of the switch is fed the backup signal – often the same material but gone a more simplified route. If something goes wrong on the main programme path you can switch to backup, but the issue is that there will be a delay because the backup has gone through less ‘boxes’.
This time difference between the main and backup signals upsets the MPEG encoder. With the MPEG encoder only transmitting differences between one frame and the next, the consequence of a sudden jump in timing is that the excessive information generated by the disrupted stream causes the MPEG encoder to reach its bandwidth limit and fall over. One frame glitch on the input to the MPEG encoder could lead to up to 15 frames of corrupted video coming out of it.
To balance the delays between the main and backup feeds you could of course use three boards – a switch and two synchronisers – but Crystal Vision saves you space and money by doing it all on one board: Safe Switch 3G.
Not only can Safe Switch 3G correct input timing differences up to one frame, it can also delay the earliest arriving input by up to 25 frames in one frame steps - making it perfect for those occasions when the backup signal has gone through less processing equipment and so arrives several frames earlier than the main input.
Safe Switch 3G is a 2 x 2 switch and you could use the second output to feed a backup redundant MPEG encoder, or your second output could go a completely different route to the transmitter after the MPEG encoder – such as via a microwave link, with the other feed going via fibre.
Another application could be to switch between the main and backup of a server system. Here the second output could be fed to a preview monitor for monitoring the servers.
Sometimes you need to switch to backup in non-emergency situations – when one of the ‘boxes’ in the chain needs fixing or updating and you want to ignore the path that the box is in.
For all these applications Safe Switch 3G will provide the most robust solution possible.
Switch it manually or automatically
Safe Switch 3G can either be switched manually or automatically – making it equally suited to planned maintenance switches or emergency transmission applications.
Manual switching takes place according to the setting of the switch timing control. Automatic switching will occur at the switching point given in SMPTE RP168:2009 when the switch timing is set to ‘Field’ or ‘Frame’, or immediately if triggered by the input missing or input video standard fault conditions.
There’s no underlying preference for either input. Being a symmetrical switch means you can select your preferred input by means of a 2 x 2 routing grid, rather than having pre-assigned main and secondary feeds.
Each of the two inputs can be switched to either or both of the two outputs, with up to two reclocked feeds of each switched signal available. The two inputs must be the same standard.
There are lots of switching options available. For example, Output B can be configured to be the opposite of Output A, making B a preview that will always show what will be transmitted if you change the switch allowing you to easily swap to a good secondary feed. Output B can be requested to be the same as Output A – like a 2 x 1 switch with more outputs.
How to get a really clean switch
With Safe Switch 3G you never have to worry about a difference in timing between your main and backup feeds – you are always going to get a clean and seamless switch.
The synchroniser in each input stream will ensure that both inputs to the switch are correctly timed to the external analogue reference so that there is no disruption during a switch. Safe Switch 3G synchronises sources between 0 and 1 frame. The synchronisers act as a self-adjusting delay, allowing a clean transition between the two channels even if their relative timing has slipped.
Safe Switch 3G can also cope with signal path delays of +/-25 frames between the two inputs and can delay the earliest arriving input by up to 25 frames in one frame steps.
It is easy to compensate for mistimed sources elsewhere in the system by adjusting the output timing relative to the reference through an entire frame using horizontal and vertical settings.
Cross-locking allows a 3Gb/s, HD or SD input to be referenced to either HD tri-level syncs or SD Black and Burst – allowing the convenient use of any existing timing signals.
Loss of reference protection
Loss of reference protection – where Safe Switch 3G will change its timing smoothly between the reference and the inputs, keeping the output valid at all times – is an unusual and technically-advanced feature which further extends the board’s primary purpose of protecting the output from any disruption.
In normal operation the output timing is derived from the reference. If the reference is lost, Safe Switch 3G will switch to input 1 or (if not available or subsequently lost) input 2 as an alternative clock source, changing to the same sample/line/frame rate as the input without disrupting the output video.
If the signal input is genlocked to the reference the output will be unchanged, while if not locked to the reference the output data rate will change smoothly, slowly drifting relative to the reference and remaining in spec at all times.
If the reference returns, the board will gently drift from the input source to line up with the reference over a period of time – again without disrupting the output signal.
Intelligent automatic switching - select from 18 fault conditions
Safe Switch 3G constantly checks both of the inputs so that the output of the switch always remains proper and valid.
It can be set to automatically switch away from the user-selected input if it does not meet the set requirements. It extracts information about various parts of the video signal to decide which of the two inputs is better, based on the engineer’s selection of which faults are significant.
The 18 video and audio parameters which can be selected to perform a switch, and which are listed in order of priority, are input missing, input video standard incorrect, EDH missing, EDH full field error, EDH active picture error, line CRC error, audio group 1 missing, audio group 2 missing, audio group 3 missing, audio group 4 missing, active video black, Ancillary Timecode missing, Ancillary Timecode frozen, active video frozen (including processed frozen picture detection) and audio silence on any channel in a selected group.
Audio silence level settings can be selected from -48dBFs, -54dBFs, -60dBFs, -66dBFs, -72dBFs, -78dBFs, -84dBFs and -90dBFs.
With some processes – such as video compression or converting to analogue and back – introducing small changes frame-to-frame even if the input picture is frozen, the processed frozen picture detection feature allows Safe Switch 3G to intelligently distinguish between this noise and real changes in the picture content – and so correctly flag up an error condition and auto switch.
Further flexibility comes from the option to set a time period of between two and 120 seconds before the video black, Ancillary Timecode frozen, video frozen and audio silence parameters trigger a switch.
Safe Switch 3G will switch away from an error on the user-selected input only if the other input is free of that fault. If both inputs have different alarms, it will use the most significant alarm to decide which feed to select. It works down the list, checking everything that has been chosen by the engineer as being of interest. As long as it does not find an error on the selected input without a corresponding error on the non-selected input, it stays with the selected input. If it finds such an error it switches to the other input.
The user can decide what constitutes a fault separately for each input - specifying what he cares about on each signal with the logic then selecting the best input. This feature provides a solution in situations where the backup signal may not contain everything required in the main signal, allowing selection between signals with different characteristics – such as a live main feed and an inherently frozen apology caption on the backup.
Following a switch it can either reselect the main feed automatically (with the option to set a time period for which the signal must be good before switching back) or by user intervention.
Safe Switch 3G will additionally report the reference video standard.
Easy to monitor for any faults
In addition to the automatic switching, two fault indications can also be set and assigned to GPIs if desired, allowing very flexible monitoring.
These fault indications are very useful, whatever type of switching you are doing. If Safe Switch 3G is set to manual switching, the fault indications will tell you that you should switch. If Safe Switch 3G is set to auto switching, the fault indications will inform you of the faults that need fixing – otherwise the board could just switch without you knowing why.
The fault indications each have their own list of chosen parameters which can be different from the auto switch selection. Each fault indication can be assigned to a specific input, to either input, or to only become active if both inputs show a selected fault. For example, you could monitor for audio silence on your main channel and get a separate indication if both channels freeze.
Fibre output connectivity - on the board
It’s easy to give Safe Switch 3G integrated fibre output connectivity by ordering the FOP fibre output option – and still only use a single frame slot. Perfect if you’re using the switch as the last point on the output of a studio and need to send the signal over a long distance to the central router or station transmission output.
Designed for SMPTE 297-2006 short-haul applications the FOP uses a Class I laser and transmits an optical output. Having the fibre output integral to the board reduces the need to use up additional rack space for separate fibre optic transmitters – as well as saving you money.
Choose your control - with the most flexible GPIs
Safe Switch 3G is used with the Statesman Lite PC control software and the VisionWeb web browser control.
Safe Switch 3G has exceptional GPIs flexibility – ideal for GPI-focused broadcasters who want to have direct control of the board. The six GPIs are all bi-directional, allowing them to be configured as either GPI inputs or GPI outputs and so giving you real flexibility when setting up buttons and lights for GPI control and monitoring of alarm conditions.
Other control options include board edge switches, an integrated front panel on the AE frames, the VisionPanel remote control panel and SNMP.
Frames, rear modules - and relay bypass protection
Safe Switch 3G is a space-saving 'single slot' 100mm x 266mm module which can be housed alongside any other products in the standard Crystal Vision frames – available in 2U, 1U and desk top box sizes. Up to 12 Safe Switch 3G modules can fit in a 2U frame.
To access the inputs and outputs, Safe Switch 3G is used with either the RM54 frame rear module for standard applications or the RM66 for fibre output applications.
The RM54 provides the two inputs, two feeds of output A, one feed of output B and an analogue reference connection.
The RM66 provides the two inputs, one optical feed of output A, one electrical feed of output B and an analogue reference connection.
The RM54 rear module includes relay bypass protection on power failure or board removal, giving the system an extra layer of security and preventing signal loss.

Output B can be requested to be the opposite of Output A, making B a preview
INTEGRATED FIBRE OUTPUT OPTION
Safe Switch 3G can be given integrated fibre output connectivity by fitting the FOP fibre output option. The FOP should be fitted at the factory
To access the optical output an RM66 frame rear module must be used
When fitted with a FOP, Safe Switch 3G can be housed in any frame slot position but due to its extra height it is not possible to place Standard Definition or audio boards directly above it when the Safe Switch 3G is in even numbered slot positions. 3Gb/s and HD boards do not share this restriction

Connector type: SC/PC
Optical power: Max -0.0dBm, min -5.0dBm (typical -2.0dBm or 630uW)
Fibre pigtail: Single-mode 8/125uM
Optical wavelength: 1290-1330nm (1310 typical)
Extinction ratio: 7.5dB
Laser safety classification: Class 1 (EN 60825), Class I (21CFR1040.10)
RELAY BYPASS PROTECTION
The RM54 frame rear module provides relay bypass protection. An electromechanical relay switch needs power to hold the switch in one state and will revert to the other state (board bypass) on loss of power. It prevents signal loss by mechanically connecting the switch’s main input to its main output 1 on complete frame power failure or board removal
Tri-level syncs or analogue Black and Burst or video
3Gb/s, HD or SD source can use either type of reference
When cross-locking it is necessary for both the video input and reference to share the same frame rate
Amplitude of syncs 150mV to 600mV
Link on PCB selects 75 ohm termination or high impedance
The framestore synchroniser in each input stream will ensure that both inputs to the switch are correctly timed to the external analogue reference so that there is no disruption during a switch
The synchronisers are intended to allow for inputs that are frequency-locked to the reference even if they are not co-timed
The synchronisation will occur solely at the start of frame point (the SAV of the switching line)
Safe Switch 3G will automatically synchronise sources between 0 and 1 frame
The timing can be fully adjusted using horizontal and vertical settings. Increasing the vertical setting will delay the output relative to the reference in increments of one line. Increasing the horizontal setting will increase this delay in increments of approx. 74ns for SD, 13.5ns for HD and 6.7ns for 3G. The output timing can be adjusted through an entire frame relative to the reference
Safe Switch 3G can cope with signal path delays of +/-25 frames between the two inputs. Input timing differences greater than one frame can be corrected by delaying the earliest arriving input by up to 25 frames in one frame steps
LOSS OF REFERENCE PROTECTION
With loss of reference protection, Safe Switch 3G will change its timing smoothly between the reference and the inputs, keeping the output valid at all times
In normal operation the output timing is derived from the reference
If the reference is lost, Safe Switch 3G will switch to input 1 or (if not available or subsequently lost) input 2 as an alternative clock source, changing to the same sample/line/frame rate as the input without disrupting the output video. If the signal input is genlocked to the reference, the output will be unchanged. If not locked to the reference, the output data rate will change smoothly, slowly drifting relative to the reference and remaining in spec at all times. To avoid disruption the output timing is not changed to match the signal input
If the reference returns, the board will gently drift from the input source to line up with the reference over a period of time without disrupting the output signal
If neither input 1 nor 2 can be relied upon, the ‘crash lock to reference when reapplied’ control allows Safe Switch 3G to hard lock to the reference when it is present. If neither input 1 nor 2 is available as an alternative reference source, the Safe Switch 3G will freerun on loss of reference. If the reference is then reapplied, Safe Switch 3G will stay in freerun mode until a hard lock to reference occurs
DELAY THROUGH BOARD
The minimum delay through the board is approximately 2500 samples, roughly 1 line in HD/3G and 3 lines in SD. The actual delay on any signal path will depend on the respective input/output timing and the delay/timing control values
Safe Switch 3G can be switched manually or automatically
Manual switching takes place either immediately or at the switching point described below, according to the setting of the switch timing control
Automatic switching will occur at the switching point given in SMPTE RP168:2009 when the switch timing is set to ‘Field’ or ‘Frame’, or immediately if triggered by the input missing or input video standard fault conditions
Safe Switch 3G will not switch away from the user-selected source if it detects that the secondary source contains an error with equal or higher priority rating than the error detected on the user-selected source
Safe Switch 3G can be set to switch back automatically or by user intervention
Automatically: the board will switch back if the original input returns to a valid state. A programmable delay of between two and 120 seconds can be added to ensure the previously faulty input remains good for the selected time period
User intervention: if the board auto switches away from a faulty input it will stay on the new selection until the routing is changed by the user, or the new input becomes faulty
Safe Switch 3G performs checks on the following parameters (listed in order of priority) which can trigger an automatic switch or activate the GPI outputs, with the user able to select a number of parameters in any combination:
* Input missing: Based on correctly positioned valid sync words in the data stream. If a valid input is not present then an alarm will be raised
* Input video standard incorrect: If a specific video standard is selected, then an input of a different standard will be treated as an error condition
* EDH missing (SD only): No EDH packets
* EDH Full Field error (SD only): Received EDH value does not match the data
* EDH Active Picture error (SD only): Received EDH value does not match the data
* Line CRC error (3G/HD only): Received CRC value does not match the data
* Audio group 1 missing: If embedded audio group 1 is missing, an alarm is triggered
* Audio group 2 missing: If embedded audio group 2 is missing, an alarm is triggered
* Audio group 3 missing: If embedded audio group 3 is missing, an alarm is triggered
* Audio group 4 missing: If embedded audio group 4 is missing, an alarm is triggered
* Active video black: If all the luma samples within the active picture area are less than 13mV from nominal black value then an alarm will be triggered. The period of time for which the picture must remain black can be set from 2 to 120 seconds. The entire active picture must be continuously black for the full period – a single non-black sample restarts the delay period
* Ancillary Timecode missing: The absence of ATC will be treated as an error
* Ancillary Timecode frozen: A repeated ATC value will be treated as an error. The period of time for which the timecode must remain frozen can be set from 2 to 120 seconds
* Active video frozen: An active picture checksum is calculated, and if it remains unchanged then the video is considered to be frozen and an alarm condition will be set. The period of time for which the picture must remain frozen can be set from 2 to 120 seconds. The entire active picture must be continuously frozen for the full period – a single non-frozen frame restarts the delay period. An adjustable threshold allows detection of frozen images that have passed through analogue links, or processing that introduces small frame-to-frame variations
* Audio silence (channels 1, 2, 3 or 4): A separate audio level checked is performed for each of the four channels in the selected group. The audio silence level setting can be selected from -48dBFS, -54dBFS, -60dBFS, -66dBFS, -72dBFS, -78dBFS, -84dBFS and -90dBFS. If the audio signal level falls below the selected level for a period of time from 2 to 120 seconds, then an alarm is triggered. All four channels share the same silence time setting. The audio on the channels must be continuously silent for the full period – a single non-silent sample restarts the delay period
Safe Switch 3G will also check the reference video standard
Safe Switch 3G allows the user to decide what constitutes a fault separately for each input
Two fault indications – Fault Indicator A and Fault Indicator B – can also be set and assigned to Statesman Lite LEDs or GPIs
The fault indications each have their own list of chosen parameters which can be different from the auto switch selection (see SIGNAL CHECKS section for list of parameters)
Each fault indication can be assigned to a specific input, to either input, or to only become active if both inputs show a selected fault (select from input 1, input 2, either or both)
