Produktübersicht
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, Robotik, und Fernüberwachungsplattformen.

FAQ
Q: I configured both RTSP and UDP streaming, but there is still no video stream output. What should I check?
EIN: 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.
- Gehe zum Video tab/page.
- Überprüfen Sie die Eingang status information. 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. überprüfen Sie bitte: 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. Nächste, please check the encoder configuration settings, einschließlich: 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?
EIN: The UDP stream is not standard MPEG-TS over UDP, but a custom low-latency protocol optimized for real-time transmission. daher, VLC may not decode it correctly. We recommend using our SPlayer, which is fully compatible and optimized for ultra-low latency playback. Bei Bedarf, 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?
EIN: Ja. Wir bieten two different firmware versions:
- Engineering (Proprietary Protocol) Firmware: Verwendet a custom low-latency UDP protocol, Unterstützt dual video inputs (SDI + AHD/CVBS simultaneous encoding), Requires our SPlayer or SDK-based player integration.
- Standard (MPEG-TS) Firmware: Verwendungsmöglichkeiten standard MPEG-TS over UDP protocol, Fully compatible with VLC, GStreamer, and other standard players, Unterstützt only one video input (SDI or AHD or CVBS) at a time, Tut not support dual-input simultaneous encoding.
Summary: 1. Wählen proprietary firmware für ultra-low latency + dual-channel encoding. 2. Wählen standard firmware für broad compatibility with VLC/GStreamer.
Q: Does the system support multicast? Can I output one stream to multiple IPs?
EIN: Ja. The system supports UDP multicast, allowing one stream to be delivered to multiple receivers simultaneously without duplicating the stream per IP. To use multicast, set the Remote-IP on the sender side to a multicast address, Zum Beispiel 224.0.0.23. All receivers join the same multicast group using the same address. On the receiver side, configure the same multicast IP:
- Splayer: set Group IP to
224.0.0.23 - VLC: offen
udp://@224.0.0.23:8090
Multicast enables one-to-many streaming within the same network. The actual device IP is not critical; stattdessen, delivery depends on network multicast support and devices joining the same group. Notiz: Network conditions may affect performance. Environments with VPNs, virtual machines, multiple network adapters, or switches without IGMP support may impact multicast reception.
