VGA to IP Encoder and Streamer
VGA to IP Encoder and StreamerVDE-265
BLANKOM VDE-265 converts VGA video and separate analog stereo audio into H.265/H.264 IP streams. Four independently configured streams and VGA/audio loop-through support legacy computer integration.
Ordering Guide
- VDE-265: specify VGA timing, audio source, codecs and destination protocols
Technical Overview
The VGA input accepts computer and VESA timings up to 1920 × 1200 at 60 Hz. VGA carries video only: audio must enter through the separate 3.5 mm stereo line input. Loop-through connections keep a local display and audio path available.
One main stream and three substreams allow different delivery profiles from the same source. The main stream supports the full input resolution; substreams are limited to 1280 × 720. Codec, bitrate and frame rate should be selected for the destination decoder and network.
The Gigabit Ethernet interface carries streaming and browser management. UDP/RTP multicast suits a managed local distribution network, while RTMP/RTMPS or SRT can connect compatible remote systems. Available protocols do not guarantee that every platform accepts every codec combination.

Typical Applications
Legacy control-room displays
Capture the VGA output of a control PC and distribute a view to compatible IP decoders. Keep the original local monitor on the VGA loop-through. Check the actual PC output timing before commissioning.
Training and presentation distribution
Use the main stream for a larger display and a lower-resolution substream for a bandwidth-limited destination. Feed speech or presentation audio through the separate line input.
Remote technical observation
Transport a computer screen to a compatible remote receiver using SRT or another agreed protocol. Size the network for the sum of active streams and the transport overhead.
