• RTSP to HDMI converter/decoder

مزیت

• Our video decoder board has H.264 video decoding and audio codec capabilities. It receives video streams through an IP Ethernet connection, decodes them, and outputs the display via HDMI and AV interfaces.
• The board offers a variety of signal outputs, including HD video at resolutions of 1080P and 720P, ویدیوی مانیتور HD CVBS با تبدیل پایین, and two channels of analog audio.
• The video decoder board also features DVR recording functionality, allowing users to record onto a Micro SD card or USB disk using dedicated recording switch controls.
• علاوه بر این, it includes a built-in RTSP server that facilitates video streaming over Ethernet for use with remote software or hardware decoders (اختیاری).
• Designed to be compact, our video board is ideal for embedded applications and enables real-time live video monitoring through wireless links or Ethernet connections.

سیگنال های ورودی/خروجی:

Power in and USB Host

The power input interface is a 2PIN PH2.54mm connector. The USB host is a 4PIN PH2.0mm connector.

 

The AV out is a 6PIN PH2.0mm connector. The Ethernet port is a PH2.0mm connector, 100M ethernet port. This video decoder board supports UDP TS video stream decoding, RTSP client decoding, and also RTSP server forward.

Data-uart and control-uart

داده ها: 3کانکتور PIN PH1.25mm, TTL 3.3 ولت. When the video decoder board works paired with our video encoder module and Ethernet linker (بی سیم یا سیمی), the uart data of the encoder module will be transferred to this uart.

کنترل uart: 4کانکتور PIN PH1.25mm, TTL 3.3 ولت. This video decoder board system can be set up via this control uart with AT command.

LEDs and Keys

The extension port is designed for assembling keys and LEDs if necessary, it’s a 2.0mm 5*2PIN connector, please view the PCB silk printing for its signals (as the photo above).

LED	شرح
برق LED	Light on when the board is normally powered
Video-LED	Blinks when the video stream is normally received and decoding
Record-LED	Light on when video is being recorded with a USB disk or TF card

OSD_key

OSD key: وضعیت نمایش OSD را روشن/خاموش کنید, and long press it to switch(بیش از 1 ثانیه). وضعیت پس از راه اندازی مجدد حفظ خواهد شد. هنگامی که وضعیت OSD بدون هیچ ورودی داده OSD از دایره داده روشن است, the system will display video information (نرخ بیت ویدیو, و غیره) on the video screen. When the OSD status is on with data input from the data uart, the system will display text information of the uart data on the video screen.

Rec_Key

Record key: switch button for video recording, short press to change its status. The system will automatically check the storage device(TF card or USB disk, priority TF card) after power on and start to record video when the storage device is inserted. Just press the button to stop or record again.

پرسش و پاسخ

س: How can I use the Rec key to record the video?

آ: After the storage device is connected, the system detects the storage device and automatically records the video.

س: Can I use the Rec_key pin?

آ: Connect a button between the REC_Key pin and the GND pin (if there is no button, simulate the button operation by short-circuiting REC_Key and GND), or use the MCU’s gpio to connect the REC_Key pin for control.

س: Do you have an appropriate box for your video LAN modules?

آ: خیر, اگر شما نیاز دارید, we have to make one metal box for you, it has extra cost.
We only provide these two boards to customers as accessories. Customers will install them in their own iron boxes. Customers will also install other boards together, so the shell is made by the customers themselves.

س: One of them has an FPGA that heats up during operation.

آ: It is normal for the operating temperature to be high during encoding and decoding. Our boards can pass high and low temperature tests at -40 درجه و 80 درجه. If necessary, you can add your own heat sink, or add a cooling fan to the case. Whether it is very hot or not is also related to the local temperature and working environment. Heat dissipation can also be achieved by using thermal conductive adhesive to stick a small heat sink of appropriate size on larger ICs such as CPU and DDR.
