- Audio and video input
- Mini HDMI interface (garso + vaizdo įrašą): 1080 60P, 1080 50P, 1080 30P, 1080 25P, 1080 60aš, 1080 50aš, 720 60P, 720 50P, 720 30P, …, various modes of adaptation;
- AV in interface (garso + vaizdo įrašą): 720×480 60aš (NTSC), 720×576 50aš (BIČIULIS), mode adaptive. When inputting audio through the AV interface, tai gali būti linijos įvestis arba mikrofono įvestis.
- Įjungus sistemą, garso ir vaizdo įvesties šaltinis aptinkamas automatiškai. Numatytoji garso įvestis yra tokia pati kaip vaizdo įvesties sąsaja. Garso įvesties sąsają taip pat galima konfigūruoti konfigūruojant nuoseklųjį prievadą. Kai HDMI ir AV garso ir vaizdo šaltiniai prijungti vienu metu, pagal numatytuosius nustatymus sistema pirmiausia fiksuoja HDMI garso ir vaizdo šaltinį. Signalas yra užkoduotas, garso ir vaizdo šaltinių rinkimo sąsają taip pat galima konfigūruoti per konfigūracijos nuoseklųjį prievadą, o garso ir vaizdo šaltinių rinkimo sąsają galima dinamiškai perjungti naudojant nuosekliojo prievado komandą sistemos veikimo metu.
Vaizdo įrašų kodavimas: H.265 arba H.264 formatu, the code rate can be configured through the configuration serial port.
Audio coding: AAC coding.

Power and indicator
The power input interface is a 2PIN 2.0mm pitch female. Two pairs of 2PIN power supply holes are reserved on the board. One pair of power supply holes are directly connected to the power input signal, and the other pair of power supply holes are exposed after anti-reverse protection. This Encode board also provides a 5V power output interface, which is convenient for the user to supply power to the cooling fan when needed. The figure below shows the power pin signals and indicators.

LED1: Power operation indicator, always on after power-on;
LED2: Video signal detection lock indicator light, this Encode board will automatically lock after detecting the video source. If the LED is not lit, the system fails to collect the video source.
LED3: Video coding work indicator, flashing during normal operation.
