SDI to HDMI Video Converter w/ Audio

The TV One 1T-VS-647 SDI to HDMI Scaler with Audio converts a variety of SDI transmission rates and video resolutions into an HDMI signal. It also provides audio flexibility by outputting the audio embedded in the SDI signal to external connectors (both analog and digital formats) for distribution separate from the HDMI data stream. Bit rates to 2.970Gb/s allow processing of resolutions up to and including 1080p. SMPTE standards 425 A&B, 424M, 292M & 259M-C are supported and SMPTE 425M level B to level A Conversion is also standard. Automatic Input Video Format Detection and an On Screen Menu display make operation easy and intuitive. Additional capabilities include SDI loop-thru with equalization and reclocking which means the 1T-VS-647 SDI to HDMI Scaler doubles as an SDI repeater. Finally, as part of the SDI to HDMI scaling process, SDI timing is automatically converted to PC timing parameters.

1T-VS-647 features include:

  • SDI to HDMI Scaler and Repeater
  • Resolutions up to and Including 1080p 60
  • Plug and Play Input and Output
  • OSD (On Screen Display) Menu settings
