Page 14: The Gxt100 Card
4. The GXT100 Card Introduction The GXT100 is a frame synchronizer and 16-channel embedder and de-embedder, combined with an ultra high-quality up/down/cross converter. The dual input capability can be used as an emergency bypass switch. The optimized scaling and filter algorithms ensure crisp broadcast-ready pictures from a native HD source, by use of 64-tap FIR filters.
Page 15 Full control and status monitoring through the front panel of the SFR04/SFR08/SFR18 frame and the Ethernet port (ACP) • 16-channel embedder in both HD and SD domains • Optional 2 fiber inputs (replacing 2 SDI inputs) or 2 fiber outputs (replacing 2 SDI outputs) on I/O panel. Synapse GXT100 | 4. The GXT100 Card |...
Page 16 Conversion Capabilities Applications • OB van output card with 16-channel embedding (in combination with 2 x DIO48) • 2 x 1 HD protection switch with SD monitoring output • Dual domain (HD & SD) production down converter with individual timing adjustment. 8 | November 2021 | Issue 1.00.B...
Page 17 The new DTV caption format cannot be translated back to EIA-608. However the EIA-708 may include EIA-608 data as "NTSC closed captions", for compatibility with old decoders. This card only de-embeds the NTSC closed captions, not the DTV closed captions. It will not function with a DTV-only 708 closed-caption source. Synapse GXT100 | 4. The GXT100 Card |...
Page 18: Settings Menu
5. Settings Menu 5.1. Introduction The Settings menu displays the current state of each GXT100 setting and allows you to change or adjust Settings can be changed using the front panel of the Synapse frame (SFR18, SFR08 or SFR04) or with Cortex.
Page 19 720p25 • 720p24 • SD525 • SD625 #Output_Map_B With this setting you can select the 3Gb/s mapping in case output B format is 1080p50 or 1080p60. Can be manually set to Level A or Level B. Synapse GXT100 | 5. Settings Menu |...
Page 20 #F_delayB F-Delay sets the amount of delayed Frames for outputs B1 and B2. The available range is from 0 to 250 fields (dependent on the I/O). Default is #V_delayB The V-Delay setting allows adjustment of the vertical phase of the output signal for outputs B1 and B2 with respect to the selected reference input. The V-Delay setting gives a delay in addition to the reference timing.
Page 21 V_only: vertical filters will be active which “soften” the image and prevents “ring”-effects in down converted content. • H_And_V: same horizontal filter as described under H_Only will be active, together with the vertical filters described under V_only. Synapse GXT100 | 5. Settings Menu |...
Page 22 • H2_Only: less steep filter with aliasing and soft for C for less ringing, more sharpness but with aliasing: • H2_And_V: same horizontal filter as described under H2_Only will be active, together with the vertical filters described under V_only. This setting is only for Channel A. Default is Off. This only works when down-converting.
Page 23 WSS (widescreen signaling) or WSS-extended (extended form of widescreen signaling). With this setting you can select which of the above protocols should be used to detect aspect ratio changes. By default it is set to VI. Synapse GXT100 | 5. Settings Menu |...

NoWSS/VI_prstA With this setting you can set to which preset the card should jump outputs A1 and A2, when no WSS or VI information is found. Can be any preset between 1 and 16 or Hold (holds current active preset). By default it is set to Hold.
Page 25 Channel A is up-converting. The best result is generated when the up-converter is active and the 601to709 setting is selected. It is also possible to switch the filter off. The default setting is Off. Synapse GXT100 | 5. Settings Menu |...
Page 26: Down-Conv
Up_CtrlB With this item you select how the presets for Channel B are controlled in up converter mode: Manually (manual), via GPI-triggers (GPI, GPI-A, GPI-B, GPI-C) or via changes of the SD Aspect Ratio (SD-AR). By default it is set to Manual. Up_Prst_ActB With this item you can manually change the currently active preset of channel B in up converter mode.
Page 27 The horizontal scaling of the TV picture of channel A in down converter mode is set using #Dn_H-scaleA. #Dn_H-scaleA can be set within the range of 50% to 200% of the input signal (only used when #Dn_ArcA is set to variable). Default value is 100%. Synapse GXT100 | 5. Settings Menu |...
Page 28 #Dn_V-ScaleA Sets the vertical scaling of the TV picture of channel A in down converter mode. Can be set within the range of 50% to 200% of the input signal (only used when #Dn_ArcA is set to variable). Default value is 100%. #Dn_H-EnhA With this item you can set the horizontal picture enhancement of channel A in down converter mode between 0 and 100%.
Page 29: Cross-Conv
Channel A in cross converter mode. Changing this will not change the active preset, unless the currently active preset is the same you are going to edit. All menu settings that are preceded with a ‘#Cr‘-prefix are part of the preset. Synapse GXT100 | 5. Settings Menu |...
Page 30 #Cr_ArcA With this item you set the Aspect Ratio of the output of channel A in cross converter mode. Can be Anamorphic, V-Zoom, CenterCut, LBox-16:9, LBox-14:9, PBox-4:3, PBox-14:9 or Variable (custom set AR, set by H-scale and V-scale settings). The following table shows the possible aspect ratios.

A priority that marks the importance of an event. This value is defined by the user and can have any value between 1 and 255, or 0 when disabled. • A slot number of the source of this event. Synapse GXT100 | 7. Events Menu |...
Page 48 Message String The message string is defined in the card and is therefore fixed. It may be used in controlling software like Synapse Set-up to show the event. Tags The tag is also defined in the card. The tag has a fixed meaning. When controlling or monitoring software has to make decisions based on events, it is easier to use the tag instead of interpreting a string.

Page 57: Appendix 2: Quad Speed Add-On Bus
Channel 1-32 (or less) are injected into the large, dark green arrow from the master card to the ADD- ON card and looped onto the next ADD-ON card via the dark green arrow. The ADD-ON card injects up to 32 channels into the large brown arrow. Synapse GXT100 | Appendix 2: Quad Speed ADD-ON Bus |...
Page 58 An ADD-ON card will also actively loop extra processed channels into the next ADD-ON card, and finally into the master card. • The cross looping of the original design is now a straight loop. • The quad speed bus can also work in one direction. You can use a Quad Speed audio bus to de-embed audio from the master and present on the ADD- ON card as AES/EBU, Bitstream (like Dolby) or analog audio.
Page 59 The next ADD-ON card (sitting in the next n+1 slot) can also freely select any 8 from 32 channels. (The DLA42 can also take 3 channels from the ADD-ON bus and 5 channels from its physical input). This looping works up to 3 times. Synapse GXT100 | Appendix 2: Quad Speed ADD-ON Bus |...
Page 60 The brown arrow is the return path and sends the (processed) audio back to the master card. This path is 32 channels wide and is clocked from the master card. The ADD-ON card can for instance overwrite 8 of the 32 channels. These 32 channels are then transported to the next ADD-ON card, which overwrites another 8 channels.
