Summary0002204: Support for streaming like video and audio
Description

We need a definition how to handle streaming requirements like video or audio streaming.

Options are

  • Semantic and data is transferred through OPC UA channel
  • Semantic is provided through OPC UA (like for File object) but actual streaming is done through another, optimized channel
Additional Information

There is a collaboration planned with ONVIF (http://www.onvif.org/). They define standards for IP-based physical security cameras (semantic + streaming).

TagsNo tags attached.

There was never a formal collaboration with the security video streaming organization.
I am not sure if there is a need for this feature in general.

A FileType like handling depends on the handling of the stream itself (in-band transfer as Data MonitoredItem or PubSub DataSetMessage vs. using dedicated streaming protocol).

For in-band transfer as Data MonitoredItem or PubSub DataSetMessage, it makes sense to model the stream as Variable that is read-only (where read makes no sense, only a subscription makes sense).

If a dedicated streaming protocol is used, the FileType like object would be needed to establish and configure the stream.

I both cases an ObjectType would be needed to provide features for stream configuration.

Waiting for concrete use case and requirements to work on this.
