- Resolution: Capable of handling 1080p (Full HD) streams, possibly multiple channels simultaneously (e.g., 4-channel or 8-channel 1080p decoding).
Memory: Usually equipped with DDR3 or DDR4 RAM (ranging from 512MB to 2GB depending on the revision) and NAND Flash or SPI Flash for firmware storage.
Interfaces:
- Video Output: HDMI and VGA ports for displaying live feeds.
- Input: Ethernet ports (RJ45) for IP camera streams (RTSP/ONVIF protocols).
- Storage: SATA interfaces for connecting hard drives (common in DVR applications).
- Expansion: GPIO headers, UART ports for debugging, and sometimes USB ports.

Integration notes (practical tips)

Match LNB voltage and connector type (usually 13/18 V via coax) to avoid hardware damage.
Use a robust power supply: noisy or underpowered sources cause lock failures or intermittent MPEG TS.
Expect to interact with the board over a serial/USB control protocol — get or reverse-engineer the control commands if documentation is sparse.
For Linux-based setups, capture MPEG transport streams via the board’s output and process them with ffmpeg, tsduck, VLC, or GStreamer.
If you plan to repackage the board, keep RF shielding and proper grounding in mind; enclosure changes can affect tuner sensitivity.
