STC-HDView5 -Decoder for Windows

Fast and Easy to use decoding software for Zao range of products

Fast and Easy Decoding Software

STC HD View is a windows based decoding software installed at the receiving end that allows operators to decode and view up to 4 incoming H.265 video streams. 

HDView5 can transcode or passthrough an incoming H.265 HEVC to either HD-SDI or to an IP Video Stream (RTSP). This can be used to push a live stream to a video management system (VMS), to a CDN, or directly to social media.

HDView5 is installed on a Win 7 or Win 10 platform (min 8GB RAM). If an HD-SDI output is required, then a Blackmagic card can be installed on the workstation.


Soliton has two other decoders - ZaoView for Linux (also available as a field based Jetson based decoder) and Cloud Zao View. Both these decoders support 4K and ultra low latency.

Key Features STC-HD View

  • Real time decoding of video and audio streams from Zao-X, Zao-S, Zao and Zao Android App
  • Up to  4-channels from 4 separate encoders/Zao streaming apps
  • 2-way audio: audio return to the transmitter
  • Operates on commodity Win 7 or Win 10/11 workstation (min 16GB RAM)

Decoder, Remote Management & Two-Way Audio


Operating on Windows 10/11 platform, HD View decodes the incoming H265 stream from the Zao X, Zao-S, Zao or Smartphone app.

Remote management includes the configuration of latency, bit rate and resolution type. It also allows 2-way audio communication (IFB) back to the camera operators in the field.

The ZaoApp for  iPhone and/or Android app can also stream live video direct to the HD-View software over the internet creating an HD-SDI output from the smartphone app. The Windows server is equipped with a Blackmagic Decklink card to provide HD-SDI out of the server.

The decoder can also output RTSO that can be used to livestream video to social media platforms such as YouTube, Facebook and other streaming media platforms, or CDN’s or Video Management Systems.
