AviWest (now HaiVision) StreamHub – customer use case – centralized management and monitoring of occasional use channels

This use case involves a project that was rolled out for a broadcaster in Denmark. Using multiple AviWest Streamhub platforms to receive, decode, and distribute live video streams, it was made possible to monitor and control all channels across all units from a single centralized user interface. DataMiner’s built-in and fully customizable visual overviews provide a graphical interface that automatically detects and adds StreamHub occasional-use channels, e.g. RIST, SRT, Zixi, or MPEG2 transport streams, and removes them again once the event has ended. For every channel, important metrics, status information, and controls are directly accessible from the interface, for example to start and stop live video distribution. The StreamHub API also provides access to live video thumbnails, which are decoded in DataMiner as well.

USE CASE DETAILS

The channel on the left is a live interview from the 2022 Olympics in Beijng. Latency and Capped Bitrate can be set directly via the embedded sliders. More detailed info on each channel, including detailed metrics, KPIs, and status information, can be accessed by the users with a single click.

DataMiner connects via the AviWest RESTful API to a StreamHub platform running either on-premises or in the cloud.

Once connected, DataMiner has access to all channels with a control option to enable or disable the Live Status.

For each channel, DataMiner reads video and audio information.

DataMiner also controls the outputs. From a drop-down, you can select any available input channel and assign that signal to one of your outputs.

This screenshot shows audio peak and delay for each input channel.

Stream statistics, e.g TX and RX bitrate, dropped, lost and retransmitted packets, are essential to monitor the health state of the video and audio elementary streams.

But also you need to know everything about the link and channel, for example round trip times.
