Common Applications
SDI Caption Bridging
Caption bridging copies captions from the source video (AUX) to the master video output. This happens
automatically when you have a captioned video input connected to the AUX connector.
Dual Encoding (Two Video Paths)
The EN537 can caption to two independent video channels, embedding the same closed captions in both
channels. Any two supported video standards can be combined on the inputs to produced closed-captioned
video on the respective outputs. For example, if 1080i60 HD-SDI is present on the Master input and NTSC
SD-SDI is present on the AUX input, the Master output will be closed-captioned 1080i60 HD-SDI and the
AUX output will be closed-captioned NTSC SD-SDI.
GPI Relocation
GPI Relocation allows on-command placement control of closed captions on your output to avoid blocking
essential action such as screen crawls and emergency information. You can control this feature by accessing
the
Main
section
of the side menu of the encoder web interface and scrolling down to the GPI settings at
the bottom.
The screen is mapped into 15 regions from top to bottom that can be protected with the use of GPI settings.
If you are creating a GPI switch and require a diagram of the GPIO Pinout – see the GPIO pinout / wiring
