The HOME UDX is an Up/Down/Cross converter with optional HDR processing. It can be used to convert one video format to another, to provide video format and aspect ratio conversions.

The app offers a de‑interlacer, an HDR/color processor, a scaler and two outputs. Each output carries the same converted signal but can use a different streaming format with a different overlay and, where applicable, can be set to "i" or "p". 

The HOME UDX delivers conversions between SD, HD, 3G and UHD as well as SMPTE ST2110, SRT and NDI®. One example would be to convert UHD to both 3G and HD, either with or without graphics - to generate simultaneous “clean” feed and “dirty” feed outputs during global events.

Users can also perform conversions from one protocol (e.g. ST2110) to another (e.g. SRT) as well as from HDR to SDR, and vice versa, in HLG and PQ using 3D LUT (.cube) tetrahedral interpolation.

This app is part of the current release of HOME Apps, and benefits from the usual advantages of a HOME Apps environment: deployment on standard network servers; instant availability; flexible resource allocation through Lawo Flex licensing; integration with external broadcast control systems, such as Lawo's VSM.

Key Features & Specification

I/O

  • 1x input receiver (RX 1): supports Video (only); Video and Audio; Video and Meta; or Video, Audio and Meta.
  • Dual output senders (TX 1 & TX 2): support Video (only); Video and Audio; Video and Meta; or Video, Audio and Meta.
    • Each output is configured separately. e.g. to use a different streaming format and/or overlay.
    • By default, Output 2 is disabled.

Video

  • Video input and output formats: SMPTE ST 2110-20, SMPTE ST 2110-22 (JPEG XS), NDI, SRT
  • Resolution*: SD, HD, 3G, UHD (3840x2160)
  • HDR <> SDR processing
    • 3D LUT (.cube) Tetrahedral Interpolation
    • Custom 3D LUT (.cube) files
  • Color space conversion:
    • BT.601 / BT.709 / BT.2020 with proc‑amp and color correction control
  • Non-linear edge enhancement
  • Optional color correction add-on

(*) JPEG-XS only supports the HD, 3G and UHD formats.

The LUTs (Look-Up Tables) must be provided by the customer.

Audio

  • Audio processing: 16 bits, 24 bits at 48kHz
  • Audio inputs and outputs: up to 8 x audio streams (send and receive); maximum of 64 channels in total
  • Fully flexible audio channel shuffling (via I/O Routing)

  • Audio processing, per channel: gain / mute / invert polarity

Delay

  • Delay is applied, automatically, to the Audio and Meta streams, to compensate for the processing delay (through the app) of the Video path. This ensures that Video, Audio and Meta streams remain in sync with each other.
  • Additional delay can be applied (by the user) to the Video stream, with or without an offset for the Audio and Meta streams. This can be used, for example, to sync the output of the HOME UDX to other video sources on the network.

Graphics Overlay

  • HTML5 overlay (transparent background for keying)

Control

  • Data sources:
    • HOME API (NATS)
    • NMOS (via HOME's NMOS Exporter)
  • Configured and managed by HOME
  • All parameters available via HOME API; allows integration with external broadcast control systems.
