製品の概要
The Vcan1731 encoder converts SDI or analog video signals into IP-based streams in real time. After encoding, the video stream is transmitted over Ethernet using RTSP or UDP TS protocols, making it suitable for both wired and wireless transmission systems.
In addition to video and audio, the module supports one channel of UART data encapsulation, allowing telemetry or control data to be transmitted alongside the video stream. This makes it highly suitable for integrated communication systems such as UAV ground links, ロボット工学, and remote monitoring platforms.

よくある質問
Q: I configured both RTSP and UDP streaming, but there is still no video stream output. What should I check?
A: Please connect the encoder board directly to your computer using an Ethernet cable.
- Open a web browser and enter: 192.168.1.30
- Log in to the encoder web interface.
- に行きます ビデオ tab/page.
- チェックしてください 入力 ステータス情報. You should see detected video input information such as: SDI 1080p30, AHD 1080p25, or other video format parameters. This information indicates that the encoder board has successfully detected the SDI/AHD camera video signal.
If no input information is displayed, the issue is related to the video input source. チェックしてください: SDI/AHD camera power supply, Video cable connection, Camera output resolution and format compatibility, Whether the camera is outputting a valid video signal
If the input signal is detected correctly, then the hardware video source is working properly. 次, please check the encoder configuration settings, 含めて: RTSP/UDP enable settings, Streaming address and port number, Network IP configuration, Bitrate and encoding parameters, Firewall or network blocking issues, VLC or player decoding settings.
For initial testing, we recommend using VLC Media Player to verify the RTSP stream connection locally before testing UDP multicast or external network streaming.
Q: Why can’t VLC play the UDP stream? Do I need special software?
A: The UDP stream is not standard MPEG-TS over UDP, but a custom low-latency protocol optimized for real-time transmission. 故に, VLC may not decode it correctly. We recommend using our SPプレイヤー, which is fully compatible and optimized for ultra-low latency playback. 必要に応じて, we can also provide an SDK and technical documentation, allowing customers to develop their own player or integrate the stream into third-party software.
Q: Can the UDP stream be changed to a standard format compatible with VLC or GStreamer? What are the differences between firmware versions?
A: はい. 我々が提供します two different firmware versions:
- エンジニアリング (Proprietary Protocol) ファームウェア: aを使用します custom low-latency UDP protocol, サポート dual video inputs (SDI + AHD/CVBS simultaneous encoding), Requires our SPlayer or SDK-based player integration.
- 標準 (MPEG-TS) ファームウェア: 用途 standard MPEG-TS over UDP protocol, Fully compatible with VLC, gstreamer, and other standard players, サポート only one video input (SDI or AHD or CVBS) at a time, する not support dual-input simultaneous encoding.
まとめ: 1. 選ぶ proprietary firmware にとって 超低遅延 + dual-channel encoding. 2. 選ぶ standard firmware にとって broad compatibility with VLC/GStreamer.
Q: システムはマルチキャストをサポートしていますか? 1つのストリームを複数のIPに出力できますか?
A: はい. The system supports UDP multicast, allowing one stream to be delivered to multiple receivers simultaneously without duplicating the stream per IP. To use multicast, をセットする リモートIP on the sender side to a multicast address, 例えば 224.0.0.23. All receivers join the same multicast group using the same address. 受信側, configure the same multicast IP:
- スプレイヤー: set Group IP to
224.0.0.23 - VLC: 開ける
udp://@224.0.0.23:8090
Multicast enables one-to-many streaming within the same network. The actual device IP is not critical; 代わりは, delivery depends on network multicast support and devices joining the same group. 注意: Network conditions may affect performance. Environments with VPNs, virtual machines, multiple network adapters, or switches without IGMP support may impact multicast reception.
