Smart Switch 3G
What is it?
3G/HD/SD intelligent 2 x 2 routing switch.
Reason to choose it...
This auto changeover switch is a price-competitive way to get immediate notification of signal problems – perfect for large systems or unmanned automatic playout facilities. With its ability to monitor an amazing 20 different video and audio parameters, you can customise Smart Switch 3G to your own needs: it will decide which of the two inputs is better based on the signal errors that are significant to you. You can trust it to always make the best decision, while it includes relay bypass protection.
Automatic monitoring of servers or other equipment where minor disruption to the output doesn't matter – such as before other processing equipment or before an MPEG encoder which is protected by a synchroniser. See who's using it.

Intelligent and automatic 2 x 2 switching
Smart Switch 3G is ideal for securing the video output in systems that demand high reliability.
This auto changeover switch provides intelligent 2 x 2 switching to a backup signal source by monitoring two 3Gb/s, HD or SD video inputs with up to four groups of embedded audio, and switching between the sources if a specified fault condition arises – no matter how subtle the fault.
If you need immediate reaction to large system signal problems or you want peace of mind for your unmanned automatic playout facility, Smart Switch 3G is a product you can trust to keep you on air.
Choosing the best input
Smart Switch 3G 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.
It features an unrivalled number of switching criteria, with the monitoring of 20 video and audio parameters on both the primary and standby inputs – and with any number of these criteria able to be selected.
Smart Switch 3G is used with the Statesman Lite PC software or VisionWeb web browser control to select the switching criteria.
One GPI can be configured using Statesman Lite or VisionWeb to show an alarm condition for any individual or group of error conditions.
Select from 20 different fault conditions
The parameters which can be selected to perform a switch, and which are listed in order of priority, are input present, input video standard, video frozen, video black, various EDH errors (SD only), line CRC error (HD only), audio group 1 missing, audio group 2 missing, audio group 3 missing, audio group 4 missing and silence on a specific audio channel.
There are also four special ‘combined conditions’ parameters which only flag an error if all the conditions are met simultaneously.
Further flexibility comes from the option to set a time period of between 2 and 60 seconds before the video black, video frozen and audio silence parameters trigger a switch.
Trust it to always make the best decision
Smart Switch 3G will switch away from an error on the main input only if the backup is free of that fault, while should the main and standby inputs have different alarms set Smart Switch 3G will work to the most significant feature to decide which feed to select.
Choose when to switch back
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.
Or...use it as a manual switch
Smart Switch 3G can also be switched manually, either immediately or in the vertical blanking period to enable a cleaner switch, with the Smart Switch 3G taking timing information from input 2 to determine the correct time to switch.
Save rack space - and protect your output
Smart Switch 3G combines intelligence with space-saving benefits, with this 100mm x 266mm module fitting in Crystal Vision’s standard frames which allows easy integration with any other products from the range.
The inputs and outputs are accessed by using the RM53 and RM54 frame rear modules, which give two outputs of the main signal and one output of the standby.
The RM54 includes relay bypass protection for the main feed on power failure or board removal, giving your system that extra layer of security and preventing signal loss.
Choose your control
Control can be from board edge switches, an integrated front panel on the AE frames, the VisionPanel remote control panel, GPIs, SNMP, the Statesman Lite PC software and the VisionWeb web browser control. Try the Smart Switch 3G VisionWeb demo...

270Mb/s or 1.5Gb/s or 3Gb/s serial compliant to EBU 3267-E, SMPTE 259M, SMPTE 292M and SMPTE 424M. Output follows the input format
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 Smart Switch 3G’s main input to its main output 1 on complete frame power failure or board removal
DELAY THROUGH BOARD
Smart Switch 3G performs checks on the following parameters (listed in order of priority) which can trigger an automatic switch or activate the GPI output, 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 (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 60 seconds. The entire active picture must be continuously black for the full period – a single non-black sample restarts the delay period
* 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 60 seconds. The entire active picture must be continuously frozen for the full period – a single non-frozen frame restarts the delay period
* Audio silence (channels 1, 2, 3 or 4): A separate audio level check is performed for each of the four channels in the selected group. If the audio signal level falls below -56dBFs for a period of time from 2 to 60 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
* Black AND channel 1 silent AND channel 2 silent: A logical combination of conditions, which only flag an error if all the conditions are met simultaneously
* Black AND channel 3 silent AND channel 4 silent: Only flags an error if all the conditions are met simultaneously
* Frozen AND channel 1 silent AND channel 2 silent: Only flags an error if all the conditions are met simultaneously
* Frozen AND channel 3 silent AND channel 4 silent: Only flags an error if all the conditions are met simultaneously
The switch timing can be either immediate or timed and will apply to both outputs
Timed switching as defined in SMPTE RP168-2002 or immediate switching if primary input is faulty and standby is free of that fault. Smart Switch 3G will not switch away from the primary source if it detects that the standby source contains an error with a higher priority rating than the error detected on the primary source
A timed switch will occur in the correct time period according to the reference input (input 2 if valid)
Smart 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 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 an invalid input it will stay on the new selection until the routing is changed by the user, or the new input becomes invalid
