  • 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
  • Remote powering according to IEEE 802.3af-2003 with increased output power

Featuring eight HDBaseT 1.x input ports, the board is compatible with the full range of Lightware TPS extenders and HDBaseT compliant third 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. 25G-8TPS2-P1-IB handles embedded audio in the HDMI substream of the HDBaseT signal and can de-embed 2-channel LPCM and various IEC 61937 audio formats from it to the Forward Audio Layer. Embedding of such audio streams from the Return Audio Layer to the HDMI signal is also supported. All audio options of the TPS2 input board are software-confi gurable on a per-port basis. The board provides remote powering for extenders according to the PoE specifi cation (IEEE 802.3af-2003) but with increased output power of 25.4W. Remote powering does not require an external power source other than that  of the 25G matrix switcher.
