Functional Modes
The SDI video transmitter and receiver module operates in various functional modes with different firmware. Default functions include:
- H.265 video compression and COFDM modulation
- Video input via SDI or AHD interface
- Full HD resolution, 1080p/i @60fps
- Adjustable working frequency, bandwidth, video stream bitrates, and RF power
The default configuration pairs with our HD5 wireless video receiver module, with video delay of approximately 200ms to 250ms. Special firmware options include:
- Standard H.264 compression (pairs with HD1/HD4 receivers)
- Proprietary H.264 compression for lowest latency (50ms-150ms)
- Dual-channel video via SDI + AHD input (requires specified firmware)
