फ़ायदा

• 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, down-converted HD CVBS monitor video, 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.
• इसके अतिरिक्त, it includes a built-in RTSP server that facilitates video streaming over Ethernet for use with remote software or hardware decoders (optional).
• 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.

सत्ता का नेतृत्व किया	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

ओएसडी कुंजी

ओएसडी कुंजी: ओएसडी प्रदर्शित करने की स्थिति को चालू/बंद करें, and long press it to switch(1s से अधिक). the status will be kept after reboot. जब ओएसडी स्थिति डेटा से किसी भी ओएसडी डेटा इनपुट के बिना चालू होती है, the system will display video information (वीडियो बिटरेट, etc.) 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.

सामान्य प्रश्न

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

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

क्यू: Can I use the Rec_key pin?

ए: 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.

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

ए: नहीं, अगर आपको चाहिये, 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.

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

ए: 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 डिग्री और 80 डिग्री. यदि आवश्यक है, 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.
