The 2GF100-110 Card

The 2GF100-110 is a dual channel frame synchronizer with backup inputs and 8 channel audio transparency and color correcting capabilities. The powerful matrix multiplexer can feed audio from the embedded domain into the Synapse bus to an ADD-ON card like the DIO48. This matrix multiplexer also allows for audio to be inserted from the ADD-ON bus into the embedded domain of the 2GF100-110. The 2GF110 adds a full audio shuffler and audio proc-amp with gain and phase control.

The 2GF100/110 also allows you to swap timecode data from channel one to channel two or vice versa, where the delay timing of the timecode is copied from the source channel.

The 2GF100/110 is compatible with 270Mb/s, 1.5Gb/s and 3Gb/s for full 1080p/50 or 1080p/59.94 use.

• 3 inputs: 2 SDI and 1 composite
• Handles complete asynchronous switching at the input
• Configurable output function
◦ Straight (1=1, 2=2)
◦ Crossed (2=1, 1=2)
◦ A only
◦ B only
• Compatible with the following input formats (auto selecting). Please bear in mind that the format and frame rate must be the same on both inputs:
◦ 1080p/59.94
◦ 1080i/59.94
◦ 1080p/50
◦ 1080i/50
◦ 1080p/29.97
◦ 720p/59.94
◦ 1080p25
◦ 720p50
◦ 1080p24
◦ SD525
 
◦ SD625
• Output standards (only one standard can be chosen for both outputs simultaneously):
◦ 1080p/59.94
◦ 1080i/59.94
◦ 1080p/50
◦ 1080i/50
◦ 1080p/29.97

◦ 1080p25
◦ 720p50
◦ 1080p24
◦ SD525
 
◦ SD625
• Two individual conversion paths. The inputs can be different standards SD, HD or 3Gb/s and unlocked to the single output format.
• Frame sync with output phase control in Frames, Lines and pixels with respect to reference. Delay setting are stored per output format for a constant latency operation.

- 1080p60
- 1080i60
- 1080p50
- 1080i50
- 1080p30
 
- 1080p25
 
- 1080p24
 
◦ 60 Frames delay offset (per channel)

• 5 GPI inputs assignable to different preset banks
◦ Input selection
◦ Output mode
◦ Audio shuffling, gain and phase (110 only)
• ARC triggers by VI, WSS, WSSext and S2016 (AFD)
• Individual color corrector for video path A and B
• Transparent for 8 channels of embedded audio per channel
• Embedded domain cross input audio shuffling, gain and phase control (110 only)
• Embedding and de-embedding through Synapse bus
• Video proc-amp (Y and C control)
• Color corrector (RGB and total gain, RGB and total black)
• Hue control for NTSC inputs
• Locks to a Bi-Level or a Tri-level sync, or to an SDI input.
• Full control and status monitoring through the Ethernet port (ACP).
 

The frame synchronizer works best if the inputs are switched according the SMPTE guidelines described in RP168.

This ensures that not only the picture but also the ancillary data remains correct. The frame synchronizer however can handle complete asynchronous switching at the input.

To ensure correct operation, the F-delay of the card needs to be 1 or higher to allow enough time to mask the error.

2GF100 / 2GF110:

• Transmission output frame synchronizer with backup input.

2GF110 only:

• Combining embedded audio channels of 2 inputs into 1 (see image below)
