2.3. デバイスインターフェース
図2.2: 背面パネルのインターフェース
This diagram clearly labels the various ports on the rear panel of the decoder: LAN (Ethernet port for IP input), RST (Reset button), LED (Status Indicators), AV Out (CVBS/Audio Out), HDMI Out (up to 4K), BNC Video Out (CVBS), and RS485 I/O.
- LAN： Ethernet port for IP video input. Configuration of the decoder's IP gateway may be required.
- LEDインジケーター: Red indicates Power ON, Green indicates Network activity.
- RST： Reset button. Press and hold until the green LED turns off to reset the device.
- AV出力： CVBS (Composite Video Broadcast Signal) and analog audio output.
- HDMI出力： High-Definition Multimedia Interface output, supporting resolutions up to 4K.
- BNC OUT: BNC connector for CVBS video output.
- RS485： Serial communication interface for control and data transfer (GND, IO-1, IO-2, 485A, 485B).

3. セットアップ
Follow these steps to set up your HaiweiTech H.265 HDMI CVBS Decoder:
- 接続電源： Connect the provided 12V 2A power adapter to the DC 12V input port on the decoder and plug it into a power outlet. The red LED indicator should illuminate.
- ネットワーク接続： Connect an Ethernet cable from your network (router or switch) to the LAN port on the decoder. Ensure your network provides access to the IP video streams you intend to decode. The green LED indicator should illuminate, indicating network activity.
- ビデオ出力接続:
- For HDMI output, connect an HDMI cable from the HDMI OUT port on the decoder to the HDMI input of your display (monitor, TV, projector).
- For CVBS output, connect a BNC cable from the BNC OUT port to your display's BNC input, or use the AV OUT port with the provided AV cable for composite video and analog audio.
- アクセス Web インタフェース： The decoder typically obtains an IP address via DHCP. To find its IP address and configure settings, you may need to use an IP scanner tool or refer to your router's connected devices list. Once the IP address is known, open a web browser and enter the decoder's IP address to access its webベースの構成インターフェース。
- Configure IP Stream: 内で web interface, navigate to the input settings. Enter the full RTSP, RTMP, HTTP, HLS, or UDP stream URL, including any necessary username and password. Ensure the syntax is correct.

This diagram illustrates how the decoder fits into a larger video system, receiving streams from an encoder via a network and outputting to a local display or user device.
4. 操作手順
Once the decoder is set up and configured with the correct IP stream, it will automatically begin decoding and outputting the video and audio to the connected display(s).
- Single Channel Decoding: For single stream decoding, ensure only one IP stream URL is configured as active in the web interface. The decoder will output this stream to both HDMI and CVBS simultaneously.
- マルチView デコード: The decoder supports multi-view decoding for up to 4 channels (2*1080P + 2*720P). Configure multiple stream URLの web interface and select the multi-view layout option if available. The decoder will combine these streams into a single output display.
- 解像度とフレームレート: The decoder will attempt to output the stream at its native resolution and frame rate, up to the maximum supported by the device (4K@30FPS). Ensure your display supports the output resolution.
- オーディオ出力: Audio embedded in the IP stream will be output via HDMI and the analog AV OUT port.
- RS485制御： If applicable, connect RS485 devices for external control or data communication as per your system requirements.
5. メンテナンス
To ensure optimal performance and longevity of your decoder, follow these maintenance guidelines:
- クリーニング： デバイスの外側を清掃する際は、柔らかく乾いた布をご使用ください。液体クリーナーやエアゾールは使用しないでください。
- 換気： Ensure the decoder is placed in a well-ventilated area. Do not block the ventilation slots on the device.
- 温度： デバイスは指定された温度範囲内で操作してください。極端な高温や低温を避けてください。
- ファームウェアの更新： 定期的にメーカーの website (if available) for firmware updates. Updates can improve performance, add features, or fix bugs.
