Industry background

The large screen in the 4K studio production and command center puts forward rigid requirements for lossless, low-latency, and long-distance transmission of audio and video signals; flickering and black screens will occur if the copper HDMI cable exceeds 15 meters.

Customer pain points

  • The cross-floor/cross-campus transmission distance exceeds the copper cable capability;
  • Multiple high-definition signals and audio, network, and control data need to be paralleled on the same fiber;
  • Uncompressed image quality requires lossless chroma sub-sampling and a delay of less than one frame;
  • Existing VGA/DVI devices require a smooth transition.

Recommended product portfolio

  • 1 channel 3G-SDI audio and video optical transceiver, adapted to broadcast-grade baseband signals;
  • HDMI/DVI/VGA non-compressed audio and video optical transceiver, zero loss of image quality;
  • 2-way/4-way HDMI+network+independent two-way audio multi-service optical transceiver;
  • Multifunctional multi-service optical transceiver, one fiber carries video + audio + data + Ethernet.

Solution value

  • Uncompressed transmission, 4:4:4 chroma is completely preserved, and large-screen splicing has no color cast;
  • The single-fiber transmission distance covers 3–20km, which can meet the requirements of outdoor live broadcast backhaul;
  • Embedding two-way audio and reverse data, the director's remote control can be completed in one stop;
  • The metal body is anti-interference and suitable for strong radio frequency environments in studios.
