  • HDMI 1.4 compliant video input over HDBaseT with a resolution of up to 4K / UHD (30Hz RGB or YCbCr 4:4:4, 60Hz YCbCr 4:2:0)
  • Pass-through of 4:2:0 3840x2160@60 Hz video input
  • Support for HDMI 1.4 embedded uncompressed LPCM audio or compressed high bitrate audio (LPCM, AC-3, MPEG1 Layer 1, MPEG1 Layer2, MPEG1 Layer 3, MPEG2, AAC, DTS, ATRAC, Dolby Digital+, DTS-HD, Dolby Digital TrueHD, DST, and WMA Pro, Dolby Digital EX, Dolby Digital Surround EX)
  • De-embedding of IEC-60958-1 (only stereo LPCM), and IEC-61937 (only AC-3, Dolby Digital Plus, Dolby Digital EX, Dolby Digital Surround EX, DTS, DTS ES
  • Video test pattern generation
  • Cable length and link quality estimation
  • Frame detector functionality with frame rate, color space, pixel clock rate, and active and total area detection
  • HDCP 1.4 support
  • Deep color support for up to 36 bpp
  • Automatic Ethernet only mode support when an Ethernet only device is connected
  • Extension for up to 170 meters over CAT6a depending on the video clock used

Featuring eight HDBaseT 1.x output ports, the board is compatible with the full range of Lightware TPS extenders and HDBaseT compliant 3rd party transmitters. The HDBaseT technology provides a transparent medium for all video, audio, data and control signals in line with the 25G multilayer architecture and allows for a cost effective extension solution for up to 170 meters.

The A3 add-on has bi-directional confi gurable Phoenix connectors. The digitized audio from the add-on can be embedded either to the output HDBaseT signal or to the Return Audio Layer. Moreover, 2-channel LPCM audio either from the HDMI signal or the Forward Audio Layer can be routed to the add-on output.
