Koninklijke KPN has been granted a patent for a system that provides a streaming client with a streaming presentation of an event by dynamically switching between multiple media streams. The system obtains source data from different recording devices and assigns quality scores to each portion of the media streams. This allows the streaming client to access the highest quality portion without manual switching. The system includes a client interface for providing the necessary data to the streaming client.

Dynamic switching between media streams for streaming presentations
A recently granted patent (Publication Number: US11778258B2) describes a system for providing a streaming client with a streaming presentation of an event. The system dynamically switches between multiple media streams obtained from different recording devices that are recording the event. The system includes an input for obtaining source data from the recording devices, which includes content data and/or metadata of concurrent portions of the media streams.
A processing subsystem applies content quality assessment functions to the source data, assigning content quality scores to each concurrent portion of the media streams. Based on a comparison of these scores, the system generates selection data that enables the streaming client to select a recording device providing access to a selected portion of a media stream. The selection data includes the content quality scores and is formatted as a metadata stream. The system also includes a client interface for providing the manifest and metadata stream to the streaming client.
The system can maintain a previous selection of a media stream when the content quality score difference between the previous stream and the selected portion is below a quality threshold. It can also generate a manifest, which is a playlist identifying different portions of the media streams for consecutive access from the recording devices.
Additionally, the patent describes a method for providing a streaming client with a streaming presentation of an event. The method involves obtaining source data from recording devices, applying content quality assessment functions to assign content quality scores to concurrent portions of the media streams, and generating selection data for the streaming client to select a recording device based on the content quality scores. The method can also involve generating a manifest and maintaining a previous selection of a media stream when the content quality score difference is below a quality threshold.
Overall, this patent presents a system and method for dynamically switching between multiple media streams to provide a streaming client with a streaming presentation of an event. The system assesses the content quality of each stream and enables the client to select the best stream based on these assessments. This technology has the potential to enhance the streaming experience by ensuring optimal content quality for viewers.
