Pangkalahatang ideya ng Produkto
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.
Bilang karagdagan sa video at 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, robotics, 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?
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.
- Pumunta sa Video tab/page.
- Suriin ang Input Impormasyon sa Katayuan. 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. Paki check na lang po: 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. Susunod, please check the encoder configuration settings, kabilang ang: 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. Kaya nga, VLC may not decode it correctly. We recommend using our Splayer, which is fully compatible and optimized for ultra-low latency playback. Kung kailangan, 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: Oo. Nagbibigay kami two different firmware versions:
- Engineering (Proprietary Protocol) Firmware: Gumagamit ng a custom low-latency UDP protocol, Sumusuporta dual video inputs (SDI + AHD/CVBS simultaneous encoding), Requires our SPlayer or SDK-based player integration.
- Pamantayan (MPEG-TS) Firmware: Gamit standard MPEG-TS over UDP protocol, Ganap na katugma sa VLC, Gstreamer, and other standard players, Sumusuporta only one video input (SDI or AHD or CVBS) at a time, Ay not support dual-input simultaneous encoding.
Buod: 1. Pumili proprietary firmware para sa Ultra-mababang latency + dual-channel encoding. 2. Pumili standard firmware para sa broad compatibility with VLC/GStreamer.
Q: Sinusuportahan ba ng system ang multicast? Maaari ba akong mag-output ng isang stream sa maraming mga IP?
A: Oo. Sinusuportahan ng system ang multicast ng UDP, allowing one stream to be delivered to multiple receivers simultaneously without duplicating the stream per IP. Upang gumamit ng multicast, itakda ang Remote IP sa gilid ng nagpadala sa isang multicast address, halimbawa 224.0.0.23. Ang lahat ng mga receiver ay sumali sa parehong multicast na grupo gamit ang parehong address. Sa panig ng tatanggap, i-configure ang parehong multicast IP:
- Splayer: itakda ang Group IP sa
224.0.0.23 - VLC: Buksan
udp://@224.0.0.23:8090
Binibigyang-daan ng Multicast ang isa-sa-maraming streaming sa loob ng parehong network. Ang aktwal na IP ng device ay hindi kritikal; sa halip, delivery depends on network multicast support and devices joining the same group. Tala: Maaaring makaapekto sa pagganap ang mga kundisyon ng network. Mga kapaligiran na may mga VPN, mga virtual machine, maramihang mga adaptor ng network, o mga switch na walang suporta sa IGMP ay maaaring makaapekto sa multicast reception.
