HDMI to HD-SDI Converter


Part Number: VUPN7978

HDMI to HD-SDI Converter

This video format converter converts video signals from HDMI to HD-SDI, 3G-SDI and SD-SDI which provides the highest quality images for professional audio-visual end users. This is a pro-audio/video quality device and suitable for installation in high-end AV systems.

Our VUPN7978 HDMI to SDI Converter is a high performance video processor for post-production and broadcast applications, providing exceptional and enhanced image processing and quality. One potential application for this device: The small size of the converter makes it easy to attach to the back of an HDMI monitor (saving hundreds or thousands of dollars over the cost of an SDI monitor.)


  • Converts HDMI to 3G-SDI, HD-SDI and SD-SDI formats
  • Supports 480i, 576i, 720p, 1080i and 1080p
  • Supports SDI (SMPTE 259M), HD-SDI (SMPTE 292M), 3G-SDI (SMPTE 424M)
  • Supports LPCM 7.1 Channel Audio
Note: To send HD video, you must use a coaxial cable with a bandwidth of at least 1.5G, for full HD video, the cable bandwidth should be at least 3G. Always use a high quality 75 ohm coaxial cable with SDI video. Lower quality cables will seriously affect the quality and reliability of the signal.

Working Distance
Max Distance via high quality 75 ohm coax cable (Belden 1505A tested)
SD (480i, 576i) (270Mbps): 300M
HD (720p, 1080i@24/25/30Hz resolution) (1.45Gbps): 200M
Full HD (1080p@50/60Hz resolution) (2.97Gbps): 100M

The device has diagnostic LED indicators for power and signal status (both input and output). Dip switches are used to set the video and audio formats. Setting of these switches is covered on the included instruction sheet.

SDI Standards / Protocols: SDI (SMPTE 259M), HD-SDI (SMPTE 292M), 3G-SDI (SMPTE 424M)
Resolutions: NTSC (480i), PAL (576i), 720p@50/59.94/60Hz, 1080ip@50/59.94/60Hz
