VIDEO OUTPUTS
Two independent ports with two outputs of the main input and one output of the standby using RM53 and RM54 frame rear modules
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
10us max

SIGNAL CHECKS
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

SWITCHING
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)
The 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
