Tunnusjoon

See kodeerimisplaat rakendab H.265/H.264 heli- ja videopakkimise kodeerimist, toetab kuni 1080p@60 kaadrit sekundis kodeeringut, ja on tagurpidi ühilduv muude erinevate eraldusvõime ja kaadrisageduse kodeerimisega.

1. 1. Heli- ja videosisestus
      1. Mini hdmi liides (heli + video): 1080 60P, 1080 50P, 1080 30P, 1080 25P, 1080 60I, 1080 50I, 720 60P, 720 50P, 720 30P, …, erinevad kohanemisviisid;
      2. Liideses (heli + video): 720×480 60I (NTSC), 720×576 50I (PAL), režiim adaptiivne. AV -liidese kaudu heli sisestamisel, see võib olla kas liini- või mikrofon sisse.
      3. Pärast süsteemi sisselülitamist, Heli- ja videosisendi allikas tuvastatakse automaatselt. Heli vaikesisend on sama, mis video sisendi liides. Heli sisendliidest saab konfigureerida ka jadapordi konfiguratsiooni kaudu. Kui HDMI ja AV heli- ja videoallikad on samal ajal ühendatud, Süsteem jäädvustab vaikimisi HDMI heli- ja videoallika. Signaal on kodeeritud, ning heli- ja videoallikate kogumisliidest saab konfigureerida ka seeriapordi konfiguratsiooni kaudu, ning heli- ja videoallikate kogumisliidese saab süsteemi toimimise ajal dünaamiliselt jadapordi käsu kaudu lülitada.

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.
