4. The GXG100-110 Card Introduction The GXG100-110 is a low-latency up, down, cross converter with 16 channel audio transparency. The powerful audio matrix multiplexer can transport audio from the embedded domain to the Synapse bus and vice versa. The GXG110 adds a full audio shuffler and audio proc- amp with gain and phase control. The GXG100-110 is compatible with 270Mb/s, 1.5Gb/s and 3Gb/s for full 1080p/50 or 1080p/59.94 use.

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 GXG100 | 4. The GXG100-110 Card |...
5. Settings Menu Introduction The Settings menu displays the current state of each GXG100/110 setting and allows you to change or adjust it. 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 #IO-Map With this setting you can configure the output as Level A (default) or Level B (according to SMPTE S425) when the output format is 1080p50 or 1080p60. Synapse GXG100 | 5. Settings Menu |...
Page 20
#F_delay F-Delay sets the number of delayed Frames. The available range is from 0 to 250 fields (dependent on the I/O). Default is 0F. The preset master for this is Out-Frmt, hence the # prefix. #V_delay V-Delay setting allows adjustment of the vertical phase of the output signal with respect to the selected reference input.
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 GXG100 | 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. When the card is in Transparent mode, the filters will be entirely bypassed. #VANC_Trans Enables or disables the transfer from input to output of selected Vertical Ancillary (VANC) lines.

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 GXG100 | 5. Settings Menu |...
NoWSS/VI_prstA With this setting you can set to which preset the card should jump channel A, 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 GXG100 | 5. Settings Menu |...
5.3. Down-Conv Setting Description Dn_CtrlA With this item you select how the presets for Channel A are controlled in down- converter mode: manually (Manual), via GPI-triggers (GPI, GPI-A, GPI-B or GPI-C) or via changes of the HD Aspect Ratio (S2016). By default it is set to Manual. Dn_Prst_ActA With this item you can manually change the currently active preset of channel A in down-converter mode.
Page 27
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%. Synapse GXG100 | 5. Settings Menu |...
#Dn_H-EnhA With this item you can set the horizontal picture enhancement of channel A in down converter mode between 0 and 100%. By default set to 0%. #Dn_ColorConvA ColorConvA optimizes the color conversion of channel A in down converter mode. As the color coding of HD (709) and SD (601) are different, it is necessary to convert these when Channel A is up-converting.

#Cr_H-ScaleA The horizontal scaling of the TV picture of channel A in cross converter mode is set using #Cr_H-scaleA. #Cr_H-scaleA can be set within the range of 50% to 200% of the input signal (only used when #Cr_ArcA is set to variable). Default value is 100%.
This setting will only work if S352_Insert is set to On. It enables you to set the colorspace in REC709 (default) or REC2020. When set to either REC709 or REC2020, the S352 data is included in the s352 packet. (This does not change anything in the picture.) Synapse GXG100 | 5. Settings Menu |...

HDR_Curve_Out The dynamic range is the range of information between the lightest and darkest part of an image, also known as an image’s luminosity. This setting enables you to set the dynamic range in standard dynamic range SDR (default), HLG, PQ or SLOG3. With all of these settings, the S352 data is included in the S352 packet.
The EVS devices can be set to de-embed either or any of the two, both for the original timecode input and the auxiliary timecode input. This can be set by AUX_Dem_Sel and ATC_Dem_Sel. When receiving an SD signal, the input line can be set separately for both normal timecode and auxiliary timecode, by VITC_ Ln_In and Aux_VITC_Ln_In.
Page 34
Aux_TC_DLY Here you set the delay in frames which should be applied to the auxiliary time code inserter. Ins_CtrlA With this item you select how the inserter presets are controlled: Manually (manual), via GPI-triggers (GPI-A, GPI-B or GPI-C), via changes of the SD aspect ratio (SD_AR) or the HD aspect ratio (S2016).
This setting can change the Audio bus order from the normal 1234 (=default) to 1324. The 1324 order is used to route the 1st group of audio from the 2nd input to the 2nd channel of a slave card (like the DIO48). Synapse GXG100 | 5. Settings Menu |...
Audio-Phase If this setting is set to Align (default), the card ensures audio-phase alignment between multiple audio channels and audio groups, which is necessary for multi-channel (surround) purposes. If errors in the signal-chain occur, the de- embedder blocks reset synchronously to maintain audio-phase alignment. If this setting is set to Off, the card eats all audio, including errors.
Page 37
Note: With this card the ADD-ON bus can only be used to either embed audio or de-embed audio. When one of the EmbXx_Inp settings is set to embed from the ADD-ON bus, no audio will be de-embedded towards the bus anymore, not for any of the channels. Synapse GXG100 | 5. Settings Menu |...
Page 38
#EmbC1_Inp_Ch ~ With these settings you can select which Channel of the selected input should #EmbC4_Inp_Ch be embedded to the corresponding output channel. Can be any channel between Ch_1 and Ch_16. Defaults for C1 till C4 are respectively Ch_9 till Ch_ (GXG110 only) #EmbD_Grp With this setting you select in to which audio group (= 4 audio channels) of the...
Please refer to "Appendix 1: GPIs Explained" on page 43 for a more elaborate explanation of the GPI settings. GPI-DebounceTime This setting allows you to specify the permitted delay for valid signals on all GPIs (general purpose inputs). Values can be from 1ms through 40ms. default is 10ms. Synapse GXG100 | 5. Settings Menu |...
5.12. Network Setting Description IP_Conf0 With this setting you can either let the card obtain an IP address automatically via DHCP, or assign an IP address manually. By default this is set to DHCP. mGW0 With IP_Conf0 set to manual, this setting lets you set a Standard Gateway. Default is set to 0.0.0.0.

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 should make decisions based on events, it is easier to use the tag instead of interpreting a string.

A-Z depending on the number of pools. The default output value of a pool is always 0. This translates to preset 1 in EVS products. In priority mode, the contact which has the highest priority defines the pool value. Priority is defined as ranging from the least significant bit (low priority) to the most significant bit (high priority).
