Productoverzicht
The Vcan1731 encoder converts SDI or analog video signals into IP-based streams in real time. Na codering, the video stream is transmitted over Ethernet using RTSP or UDP TS protocols, making it suitable for both wired and wireless transmission systems.
Naast video en 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, robotica, and remote monitoring platforms.

FAQ
Q: I configured both RTSP and UDP streaming, but there is still no video stream output. What should I check?
EEN: 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.
- Ga naar de Video tab/page.
- Controleer de Invoer statusinformatie. 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. Gelieve dit na te kijken: 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. volgende, please check the encoder configuration settings, inclusief: 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?
EEN: The UDP stream is not standard MPEG-TS over UDP, but a custom low-latency protocol optimized for real-time transmission. daarom, VLC may not decode it correctly. We recommend using our SPspeler, which is fully compatible and optimized for ultra-low latency playback. If needed, 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?
EEN: Ja. Wij bieden two different firmware versions:
- Engineering (Proprietary Protocol) firmware: Gebruikt een custom low-latency UDP protocol, steunen dual video inputs (SDI + AHD/CVBS simultaneous encoding), Requires our SPlayer or SDK-based player integration.
- Standaard (MPEG-TS) firmware: Gebruik standard MPEG-TS over UDP protocol, Volledig compatibel met VLC, Gstreamer, and other standard players, steunen only one video input (SDI or AHD or CVBS) at a time, Doet not support dual-input simultaneous encoding.
Samenvatting: 1. Kiezen proprietary firmware voor ultra-lage latentie + dual-channel encoding. 2. Kiezen standard firmware voor broad compatibility with VLC/GStreamer.
Q: Ondersteunt het systeem multicast?? Kan ik één stream naar meerdere IP's uitvoeren??
EEN: Ja. Het systeem ondersteunt UDP-multicast, allowing one stream to be delivered to multiple receivers simultaneously without duplicating the stream per IP. Multicast gebruiken, Stel de Externe IP aan de afzenderzijde naar een multicast-adres, bijvoorbeeld 224.0.0.23. Alle ontvangers sluiten zich aan bij dezelfde multicastgroep met hetzelfde adres. Aan de ontvangerkant, configureer hetzelfde multicast-IP:
- Splayer: stel Groeps-IP in op
224.0.0.23 - VLC: open
udp://@224.0.0.23:8090
Multicast maakt one-to-many-streaming binnen hetzelfde netwerk mogelijk. Het daadwerkelijke IP-adres van het apparaat is niet kritisch; in plaats van, delivery depends on network multicast support and devices joining the same group. Notitie: Netwerkomstandigheden kunnen de prestaties beïnvloeden. Omgevingen met VPN's, virtuele machines, meerdere netwerkadapters, of switches zonder IGMP-ondersteuning kunnen de multicast-ontvangst beïnvloeden.
