Q: Apakah Anda memiliki modul perangkat keras atau perangkat lunak yang mengimplementasikan fungsi OSD? Saya memerlukan video dan telemetri untuk dikirim dalam paket UDP yang sama dengan sinkronisasi tinggi.
SEBUAH: Sistem kami mendukung transmisi UDP dan dapat mengirimkan data video dan telemetri secara bersamaan. Namun, mereka dikirim dalam paket UDP terpisah. Jika Anda memerlukan video dan telemetri dalam satu aliran, OSD harus dilapis di bagian depan (MISALNYA., di dalam kamera, gimbal, atau pembuat enkode) sebelum data memasuki tautan nirkabel.
Q: Bisakah video dan telemetri dikemas ke dalam satu paket UDP? Ini penting untuk aplikasi saya.
SEBUAH: Tidak. Video dan telemetri ditransmisikan dalam paket UDP terpisah.
Q: Saya butuh frekuensi rendah, saluran berbeda untuk TX dan RX, dan input RJ45 untuk kamera digital saya (mereka tidak mendukung HDMI, hanya Ethernet). Bisakah Anda mendukung ini?
SEBUAH: Iya. Video input is via the Ethernet port, and telemetry input is via the data port. These are transmitted as separate UDP packets. If you need video and telemetry combined into one stream, you must overlay telemetry onto the video at the front end using OSD. Most IPCs, payload pods, or even analog systems support this feature.
Q: Does the 1886 module pack each video frame together with telemetry data into a single UDP packet?
SEBUAH: Itu 1886 module functions as a wireless link for transparent transmission. It transmits the data you provide (video atau telemetri) without modification. In some configurations, telemetry can be converted into network port data and transmitted alongside video data, but integration into the same UDP packet must be handled at the front end before entering the module.
Q: I want to transmit telemetry from the flight controller (Mavlink 2 protokol) and a video stream from the camera (RTSP), pack them into one UDP packet, and send them to the ground with precise frame synchronization. Can your module do this?
SEBUAH: Itu 1886 module supports transparent transmission of both Mavlink telemetry and RTSP video via UDP. Namun, video and telemetry are inherently different in size and frequency, making precise synchronization within the same UDP packet very difficult. The air unit accepts both video and telemetry inputs and the ground unit outputs them separately. If you require strict synchronization, telemetry should be overlaid onto the video at the front end before transmission.
Q: Can video and telemetry be transmitted in exactly the same UDP packet?
SEBUAH: Tidak. The module transmits whichever packet (video atau telemetri) arrives first. Both types of data are queued for transmission, and whichever arrives earlier is sent immediately. The delay between video and telemetry packets is very small (only a few milliseconds), but they are not merged into one packet.
So vcan1886 supports UDP transparent transmission of different package on unequal uplink and downlink frequencies.
