3 Module Description The IQSYN20 provides synchronization for HD-SDI 1.5 Gbit/s or SD-SDI 270 Mbit/s signals. Using agile synchronization that is router switching tolerant makes this module ideal for lines input applications using SDI video signals. A video proc. amp provides complete control over the video levels, and additional video delay is available. A particularly powerful feature for constructing simple solutions to difficult system problems is the router at the input to the synchronizer. That means that the IQSYN20 can easily be placed at the end of main and redundant feeds or be used where an HD-SDI feed is complemented by an upconverted SD- SDI or even a digitized and upconverted analog feed.

8 IQSYN20 Connections This section describes the physical input and output connections used by the IQSYN20. Input Connections Serial In The serial digital input is made to the unit via a BNC connector which terminates in 75 Ohms. 2 SERIAL IN Reference Input The external sync input to the unit is made via the passive loop-through BNC connectors for 75 Ohms. It should be noted that proper operation to the full specification can only be achieved with a correctly terminated, noise-free, stable, black sync reference input. Whilst lock may be achieved with an unsuitable sync source the increased jitter evident on the SDI output will affect locking and cable length performance at the receiving equipment. Note: If the loop-through facility is not used the unused BNC socket must be fitted with a 75 Ohm terminator. IQSYN2 _27-2A Output Connections Serial Digital Video Outputs These are the Serial Digital outputs of the unit via BNC connectors for 75 Ohms. IQSYN20 18/09/2009 Page 8

9 GPI (2A Version) There are the two GPI connections via BNC connectors that may be configured as inputs or outputs. GPI (1A version) There is one GPI connection via a BNC connector that may configured as an input or output. IQSYN20 18/09/2009 Page 9

10 Card Edge Indicators The LEDs on the edge of the IQSYN20 indicate the operating status of the module. + Power OK Indicates that a positive power supply is present. - Power OK Indicates that a negative power supply is present. CPU OK FPGA Done (Yellow) IN 1, IN 2 (Green) SDI Error (Red) Ref Lock (Green) Error (Red) This LED flashes when the CPU is running. Flashes when the FPGA is running. When the unit is booting, this LED is illuminated, until the SDI is enabled. These LEDs indicate which input has been selected. This will become illuminated if any CRC, EDH or TRS errors are detected on the selected SDI input or a loss of SDI. This LED will be illuminated when genlock is enabled and locked. This LED indicates board fault conditions. These include: Serializer lock fault. Output serialiser fails to lock. SDI JTAG board fault. Internal JTAG interface is inadvertently enabled. In all cases continuous illumination indicates a board fault and a service is required. Perform a Factory Reset and supply a valid SDI video source before calling service. When the unit is booting, this LED is illuminated, until the SDI is enabled. Warning (Yellow) This indicates operational errors. These include: Input Video - Incompatible input standard. Detected input standard is invalid. Input Video - SDI problem. CRC or other SDI errors detected on selected input in the last whole field. Reference - Lock Failure. Genlock failed to lock to selected source. Will generally light up in transitional states like standard changes, but continuous illumination indicates a problem. More information is available in the status window. OK (Green) Indicates that the module is operating correctly. IQSYN20 18/09/2009 Page 10

11 Controlling the IQSYN20 from the RollCall Control Panel The Information Window The information window appears in the upper-right corner of each screen and displays basic information about the audio and video status of the unit. Select either Video Status or Audio Status to display the corresponding information. The following Video Status information is displayed: Line One Displays the status of the video input, followed by the standard of the input, or last valid signal. INP:OK The unit is receiving a valid input signal of a recognized standard. INP:LOST The unit is not receiving an input signal. INP:FAIL The unit is receiving an input signal, but the signal is not valid. For example, the frame rate differs between the input and output standards. INP: MISM The unit is receiving a valid input signal, but in a different format to the selected output standard. For example, in 1080/29i, out 1080/29p. Line Two Displays the operating standard of the unit. OUT: The input signal standard is not recognized. Unknown OUT: The operating standard. 1080/29i (For example) Line Three Displays the status of genlock, followed by the standard of the analog reference signal when in Free-Run or Lock to Reference mode. Ref: Free Free run, with no reference connected. REF: OK F Free run. 1080/29i REF: LOCK Valid reference and unit genlocked. 1080/29i REF: LK-F Valid reference but ambiguous field type. REF: LOST No reference signal found. REF: FAIL Genlock not possible. REF: FAIL Failed to genlock to input. INP REF: LOCK Genlocked to input video. INP IQSYN20 18/09/2009 Page 11

12 Line Four Displays the status of the ancillary data and the output picture. ANC Ancillary present. FRZ Output frozen. PAT Output pattern. MON Monochrome. HBL Horizontal ancillary data is being blanked. BLK Output black. When Audio Status is selected, the status of the embedded audio input is displayed where: p D Indicates that the channel is a PCM audio input. Indicates that no audio input is detected Indicates that the signal is data (non-pcm, Dolby, etc ) IQSYN20 18/09/2009 Page 12

13 Video Input Use the settings on the Video Input screen to: Select the input source. Enable any specified backup rules. Specify the condition that must exist in order for the unit to consider input to have been lost. Specify valid input standards. View information about CRC/EDH errors. Input Select This allows either input 1 or Input 2 to be selected for processing. Backup Enable When selected, if a backup rule is triggered, the action defined in the backup rules takes place. For details please see page 32. Input Loss If The module can take automatic action if the input signal is lost. This control defines what is considered to be a loss of input and so what will cause the automatic actions to be triggered. No Input: If there is no input signal of any type this will be considered to be a loss of input. In/Out std. Mismatch: If the standard of the input signal does not match the output standard this will be considered to be a loss of input. Agile V-Lock This function is intended to permit correct reception of upstream switched misaligned 625/25i and 525/29i sources without picture disturbance. In HD standards, a mechanism is in place to re-synchronize after a switch, which makes this mode unnecessary. A tolerance of +/- 5 lines IQSYN20 18/09/2009 Page 13

14 misalignment between sources is permissible which is wider than the 5 µs allowance specified in SMPTE RP-168, and it is assumed that the correct switch point with respect to the source is used. Notes: Due to the time required to recognize a change in picture framing in standard definition (SD) there must be a minimum delay of 4 lines so that no displaced picture is seen at the output during a misaligned switch. This may be assured in a synchronizing mode (external reference or free-run) by setting the Frames delay value to at least 1. Application areas that require agility over delay will suit this function better. Poor and unstable signals may benefit from having this function disabled Correct operation of agile V-lock requires a correct vertical reference point. On some legacy equipment from before 1995 the end of vertical blanking was on the permissible lines as well as on the current line 20. This practice is no longer permitted, and will prevent correct vertical alignment of non-compliant legacy 525/59i sources. If this is the case then disable Agile V- Lock. Valid Input Standards To specify the video input standards that the unit will accept, select the corresponding check boxes. To select all check boxes, click Set All. To clear all check boxes, click Clear All. Note: If any other standards are detected, an invalid standard will be assumed and this will force an input video loss with the FAIL status. CRC/EDH Errors This item provides information about the Cyclic Redundancy Checksum errors (CRC) and Error Detection Handling (EDH). CRC/EDH Errors: This displays the total CRC or EDM Full Frame error count since the last reset. Time Since Last (CRC/EDH) Error: This will show the time in 5 second intervals up to 1 minute then in minute intervals, since the last error was detected. ANC Errors: This will display the total number of ANC errors since the last reset. All ancillary packets are checked. Hence, a problem video source or dropout can produce a large number of errors. Time Since Last (ANC) Error: This will show the time in 5 second intervals up to 1 minute then in minute intervals, since the last error was detected. Reset Counts: This will reset the error counters to zero. Time Since Reset: This will show the time in 5 second intervals up to 1 minute then in minute intervals, since the counters were last reset. Note: If the selected input changes, the CRC/EDH counts will be automatically reset once the software has decided that the input is correctly locked. IQSYN20 18/09/2009 Page 14

15 Video Output Use the settings on the Video Output screen to: Specify the video output standard. Set up the test pattern, if any, to be generated. Specify the default output to be generated in response to a loss of input. Adjust the signal gain and black levels. Control the unit s monochrome functions. Control the unit s picture freeze function. Note that for this and other screens the following applies to the scroll bars: The and symbols at the ends of the scroll bar allow the value to be adjusted in discrete steps. The numerical value will be shown next to the scroll bars and selecting Preset the setting to the calibrated value for that item. will return Output Select the output standard from the following list: 1125(1080)/30i 1125(1080)/24p 1125(1080)/24sf 1125(1080)/25p 1125(1080)/29p 1125(1035)/30i 1125(1035)/29i 1125(1080)/23p 1125(1080)/23sf 750(720)/50p 525(480)/29i 750(720)/60p 750(720)/59p 1125(1080)/25i 1125(1080)/29i 625(576)/25i 1125(1080)/30p IQSYN20 18/09/2009 Page 15

16 Output Standard This function defines how the output standard is selected. Manual Selection: When checked the output standard will be the one selected via the Output/Output Standard list. Follows Input: When checked the output standard will be set to be the same as the input standard. Follows Reference: When checked the output standard will be set to be the same as the reference input standard. Note: If you have selected Follows Input or Follows Reference, you can pre-select the output standard for use with the Manual Selection option. If you then select Manual Selection, the specified standard is used. Pattern This allows the pattern functions to be set up. Enable: When checked, the output will become the pattern selected from the Pattern Type list. H-Scroll: When checked, the selected pattern will scroll from left to right at a fixed rate. This mode is useful for differentiating between an input test pattern signal that has become a frozen picture (caused by a loss of input signal) and a test pattern that has been chosen to be the output. Pattern Type This allows a pattern to be selected from the list. This pattern will become the output signal when Pattern/Enable is checked. Options are as follows: 100% Color Bars Ramp 75% Color Bars Sweep SMPTE Bars Pulse & Bar Tartan Bars Burst Pluge Black Default Output This controls the units' response to a loss of input signal as set via the Video Input/Input Loss if and Valid Input Standards functions. Options are: Freeze Frame: When checked the output will become a frozen frame picture. Freeze Field: When checked the output will become a frozen field picture. Black: When checked the output picture will cut to black. Input: When checked the incoming signal will be displayed whenever possible. Out Pattern: When checked the output picture will become the pattern selected via the Output/Pattern Type function. ProcAmp This function allows the gain and black level of the signal to be adjusted. Master Gain: This allows the overall gain (Y and Cb/Cr) to be adjusted over a range of ±6 db in steps of 0.1 db. Preset value is 0.0 db. Y and C gain may be independently adjusted with the controls described below. IQSYN20 18/09/2009 Page 16

17 Y Gain: This allows the Y (luminance) gain to be adjusted by ±6 db in steps of 0.1 db. Preset value is 0 db. C Gain: This allows the Cb/Cr (color difference) gain to be adjusted by ±6 db in steps of 0.1 db. Preset value is 0 db. Note: The total range of both Master + Y and Master + C controls is +6 db to -10 db. Black Level: This allows the black level to be adjusted by ±200 mv in steps of 1 mv. Preset value is 0. Utilities The Monochrome settings control the unit s monochrome output functions. Enable: When checked, the monochrome functions will be enabled. Monochrome Type Y Only: When selected, the output picture will become monochrome using only the Y component of the signal. C Only: When selected, the output picture will become monochrome using only the CbCr components of the signal. The Freeze settings control the picture freeze function. Force Freeze: When checked the output will become a frozen picture. Freeze Type: The frozen picture may be chosen to be either a frozen Frame or a frozen Field. IQSYN20 18/09/2009 Page 17

18 Video Delay/Genlock As a frame-based video synchronizer with up to 1 frame of storage, there are many possibilities for timing the output video. Each has an impact on delay through the unit and the possible level of control. Of these there are two classes of operation Referenced modes and Delay Modes. Referenced modes In a referenced mode, video output is independently timed from the input, so that the output is always aligned to the reference raster to match other equipment for switching and processing purposes. This is the normal frame synchronizer operating mode, in which it will always have a good whole frame of video to display (whether live, frozen, black or test pattern). As well, due to the independence of the output timing, it will be able to "firewall" the video. For more information, see the Firewall section on page 72. The delay through the unit remains within the one-frame operating range of the buffer, but cannot be directly controlled since it is externally defined by the output and input references. However, phasing relative to any external output reference is adjustable. Delay modes (Lock to Input) Delay modes use the input reference to determine the output reference. These are not synchronizing modes, but are utility delay generation mode which may be useful when the audio processing or a simple delay is required. The output will be stable only if the input is stable so it is not a viable firewall mode The total delay is summed from calculated and measured delays to a resolution of one video line, and shown in the Internal Delay box. This is then available for use in the tracking Audio Delays. Genlock The Genlock function enables you to specify the Genlock or Video Delay mode, which defines the source of timing for the output video. Free Run This is a special case of referenced type mode. When selected, the unit's output will not be locked to any input signal. Instead, it will run nominally at the correct frame rate and IQSYN20 18/09/2009 Page 18

19 synchronize input video to this. Its most likely use is to stabilize and firewall poor sources in the absence of a station reference. This is the Factory Defaults preset. Lock to Reference This is the normal referenced mode. When selected, the unit will lock to an external black (burst) reference signal, either bi-level SD or tri-level HD. Horizontal or Vertical Timing adjustments are possible for correctly phasing to match other sources. Its most likely use is to stabilize, firewall and correctly phase (synchronize) incoming line or post-router switched sources to a station reference. This reference should be correctly terminated and clean of noise and jitter to give the best possible results. A bi-level reference of the correct frame rate is always acceptable, but a trilevel HD reference is only acceptable for a HD output. There are many cross-locking modes possible, and for this purpose the correct frame rate is either the output frame rate or double or half the rate - when an interlaced output is referenced to a progressive source the field relationship is unknown and this is indicated with REF: LK-F in the status window. When an unsuitable reference is given the unit will fail to lock and REF: FAIL will show in the video status window. In this mode, Reference Status displays the amplitude of the reference sync signal, either peak for bi-level (typically 300 mv) or peak-peak for tri-level (typically 600 mv). Note that unterminated tri-level syncs will have the indication clipped to around 1 Volt. IQSYN20 18/09/2009 Page 19

20 Input Manual H and V This allows the adjustment of the delay by changing the vertical and horizontal timing. When a delay is required to be defined in terms of video lines, maybe to round up to the next frame boundary, this mode can be used. However, it may introduce complications on changes of video standard, and the minimum delay can go below the 0.75 ms audio minimum delay that would permit delay matching. Vertical Timing Vertical Timing allows the video delay to be adjusted in steps of one line. The range of adjustment is one line short of an output frame in either direction. The preset value is 0 lines. Horizontal Timing Horizontal Timing allows the video delay to be adjusted in steps of one line. The range of adjustment is one pixel short of an output line in either direction. The preset value is 0 pixels. The total delay is the sum of Vertical Timing + Horizontal timing. An overall effect is to allow a delay of 1 frame - 5 lines, for example, to align an earlier 5-line delay device to the next frame boundary. The sum of horizontal and vertical timing is post-limited to be under +/- a frame of the current standard. There is also a forced minimum delay of 1 line. Internal Delay This displays the value of the current delay in milliseconds. This is useful to check that a suitable delay has been set. Notes: When the delay is set below the minimum possible, this control will limit at 1 video line. When the delay is set above the maximum possible, this control will limit at just below 1 video frame. IQSYN20 18/09/2009 Page 20

21 HANC & VBI Blank(ing) VBI for Standard This item allows the Vertical Interval data (all or specific lines) contained in the input signal to be blanked or passed through the module. It allows the selection of which vertical interval lines to pass through to the output and which lines to blank. Standards that may be selected are as follows: 1125(1080)/30i 1125(1035)/30i 1125(1080)/30p 1125(1035)/29i 1125(1080)/29i 750(720)/60p 1125(1080)/29p 750(720)/59p 1125(1080)/25i 750(720)/50p 1125(1080)/25p 525(480)/29i 1125(1080)/24p 625(576)/25i 1125(1080)/24sf 1125(1080)/23p 1125(1080)/23sf In the example shown, the 1125(1080)29i standard has been selected and VBI lines 8 to 20 and 571 to 583 are displayed. Different standards will display different VBI lines. Blank Lines To prevent specific lines from being passed to the output signal, select them from the Blank Lines section. To allow all displayed vertical interval lines to be passed to the output signal, click Pass All Lines. To prevent all displayed vertical interval lines from being passed to the output signal, click Blank All Lines. IQSYN20 18/09/2009 Page 21

22 Input Ancillary The Input Ancillary controls enable you to specify whether to: Remove all ancillary data. Remove only horizontal ancillary data. Allow ancillary data to pass unaltered Remove all ancillary data, if input signal fails to match the output standard. To remove all ancillary data, select Blank All. This overrides the VBI Blank Lines control. To remove horizontal ancillary data (HANC), select Blank HANC. To allow ancillary data to pass unaltered, select Pass. When Pass is selected, pass-through operations will not alter audio packets for groups that the IQSYN20 has not selected for embedding. To remove all ancillary data, if the input signal fails to match the output standard, select Blank All on STD mismatch. IQSYN20 18/09/2009 Page 22

23 GPIO (General Purpose Input Output) This screen allows the GPI functions to be configured. Note: GPI/O 2 is only valid for the double width module. GPI/O 1 and GPI/O 2 This allows GPI to be configured in the following ways: Unused: GPI is inactive. Input: GPI is configured as an input. Output: GPI is configured as an output. GPI 1 (Input) or GPI 2 (Input) When the GPI is configured as an input, this item allows an action to be chosen that will occur when the GPI input is grounded or, if the Invert function is selected, becomes open. The options are as follows: Unused This allows a direct GPI to RollTrack without calling the other states. Freeze The output picture will be frozen. When released (input open) the output picture will be unfrozen. Pattern The output picture will become the selected pattern. When released (input open) the output picture will revert to normal. Black The output picture will cut to black. When released (input open) the output picture will revert to normal. Blank Ancillary Ancillary data will be blanked. When released (input open) ancillary data will be passed. MonoChrm Y Only The output picture will become monochrome using only the Y component of the signal. When released (input open) the picture will revert to normal color. IQSYN20 18/09/2009 Page 23

24 MonoChrm CbCr Only The output picture will become monochrome using only the CbCr components of the signal. When released (input open) the picture will revert to normal color. Use I/P Ref (SDI) The unit will lock to the video input. When released (input open) the unit will revert to the Free Run mode. Use Ext Ref (Analog) The unit will lock to the reference signal. When released (input open) the unit will revert to the Free Run mode. Select Inp 1, Select Inp 2 Input 1 or Input 2 will be selected. Select Input This is a toggle function that selecting between Input 1 and Input 2. Select Backup This will enable the Backup Rules function. When released, the Backup Rules function will be disabled. Memory 1 to 16 The unit will revert to the setup stored in the selected memory location. When released (input open) this state will remain; i.e. it will not revert to the previous state. GPI Input Edge Switching Operation With the exception of Memory Recalls 1-16, the GPI input will switch on both edges, hence the switch to the inactive state will perform the reverse function. This may override any other control operations performed while the GPI was active. GPI 1 (Output) and GPI 2 (Output) When the GPI is configured as an output, this item allows an action to be chosen that will produce an output signal at the GPI connector. The GPI output will be driven to ground or, if the Invert function is selected, becomes open. The options are as follows: Input 1 (or 2) OK An output signal will be produced if the HD SDI input is present and OK.

27 Define Input OK This defines what is considered as Input 1 (and 2) is OK when Present and conforms to any of the parameters selected from the following list. Valid i/p Standard EDH/CRC is OK Audio Pair 1 present Audio Pair 2 present Audio Pair 3 present Audio Pair 4 present Audio Pair 5 present Audio Pair 6 present Audio Pair 7 present Audio Pair 8 present These extra tests are only possible for the currently selected video source, when the other input is selected they are assumed to be true. So unexpected results may occur when these are used for a high priority switch - always test your rule set before relying on it. IQSYN20 18/09/2009 Page 27

28 Backup Rules 1-3 and 4-5 Backup rules are used to define the action taken by the unit when a specified event occurs. For example, a backup rule could be defined such that if an error condition exists on Input 1, the unit switches to Input 2. Action Either Select Input 1 or Select Input 2 may be chosen as the action taken when an event chosen from the following list, occurs. Off (function is not available) Input 1 is OK Input 2 is OK Input 1 in Error Input 2 in Error GPI 1 Open GPI 1 Closed GPI 2 Open GPI 2 Closed Time Delay For each rule it is possible to set a time delay. This is the length of time that the rule must be evaluated as true for before activating the action. If the rule is evaluated as false before the set time expires the action will be prevented and the time reset. IQSYN20 18/09/2009 Page 28

29 In the example below, Input 1 will be selected if the rule is evaluated as true (i.e. GPI 1 has become open) for over 5.1 seconds. Each rule is evaluated in turn. Rule one is evaluated first. If the condition specified for rule one occurs for the duration of the specified time delay, action one occurs. Otherwise, rule 2 is tested, and so on. IQSYN20 18/09/2009 Page 29

30 Memory The Memory function allows you to save up to 16 configurations, which can be recalled later. You can rename the 16 memory locations to provide more meaningful descriptions. You cannot store more than 16 configurations in memory. Save Memory The save memory function allows you to store up to 16 configurations. To save the settings, in the Save Memory area, select a memory location and click Save. The module s current settings are saved. To clear a memory location, in the Save Memory area, select a memory location and click Clear. The settings stored for that memory location are cleared. After you clear a memory location, it disappears from the Recall Memory list. To change a memory name, in the Save Memory Name field, type the new name (the return symbol changes to red ), and then click to save the new name. The symbol will then become black again. Selecting Preset will return the text to the default name. Recall Memory The recall memory function enables you to recall previously saved configurations from memory. The Recall Memory list is empty until you Save a Memory. To recall memory settings, in the Recall Memory area, select a memory location. The new settings are applied and the memory name appears in the Last Recalled Memory function area. IQSYN20 18/09/2009 Page 30

32 Address This item allows the address of the selected destination unit to be set. To change the address, type the new destination in the text area and then select (return) (Preset) returns to the default destination The full RollTrack address has four sets of numbers, for example, 0000:10:01*99. The first set (0000) is the network segment code number. The second set (10) is the number identifying the (enclosure/mainframe) unit. The third set (01) is the slot number in the unit The fourth set (99) is a user settable number that is a unique identification number for the destination unit in a multi-unit system. This ensures that only the correct unit will respond to the command. If left at 00 an incorrectly fitted unit may respond inappropriately. Command The full RollTrack command has two sets of numbers, for example: 84:156. The first set (84) is the RollTrack command number. The second set (156) is the value sent with the RollTrack command number. For details of RollCall command values please refer to page 52. RollTrack Sending This item shows when the unit is actively sending the RollTrack command. String A string value is always being sent. Number A number value is always being sent.
