FAQ



Q: What is the purpose of using a DVB-T modulator with an IR return path?



A: The primary purpose is to distribute digital video and audio signals over terrestrial networks while also allowing for remote control of the source device using an infrared (IR) remote control.



 



Q: How does the IR return path work?



A: The IR return path feature allows remote control signals from IR remote controls to be sent back to the source device through the same coaxial cable used for distributing the DVB-T signals. This enables remote control functionality for the source device from a remote location.



 



Q: Can the IR return path be used with any IR remote control?



A: Yes, the IR return path is typically compatible with most IR remote controls commonly used with televisions and other audio-visual equipment.



 



Q: How is the IR return path connected and configured?



A: The IR return path typically requires an IR receiver/transmitter device connected to the DVB-T modulator and positioned in a location where it can receive IR signals from remote controls. The IR signals are then sent back to the source device through the coaxial cable.
