  • Publication number: 20210233340
    Abstract: A system for entrance permit control is configured to monitor individuals in an entrance region that includes an entrance to a restricted area. The system performs a monitoring method to enable a seamless entrance experience for the individuals. The system receives a stream of digital images of the entrance region, and processes the received stream of digital images for detection of a machine-readable code, MRC, displayable on an entrance permit carried by an individual in the entrance region. The system further tracks, based on the received stream of digital images, a location of the MRC within the entrance region, initiates a validation of the MRC, and provides, in dependence of the validation and position data generated by the tracking, a visual indication of a result of the validation on at least one of the entrance permit and the individual.

  • Publication number: 20210211481
    Abstract: The media production element (12) combines media content from a plurality of streaming electronic devices when they are registered to be within the same streaming event. The media production element (12) can produce a combined live video stream or a combined media production using selections and combinations of the streamed content provided by the multiple electronic devices. A network assistance device (42) can determine event-coordinated uplink network assistance data with the goal of prioritizing resource allocation to clients/electronic devices that currently are used for the combined media production, and assign less resources to those that are not currently used. Rather than optimizing individual links, the event-coordinated uplink network assistance data is determined by taking the aggregated capacity and the production needs of the media production element (12) into account.

  • Publication number: 20210204035
    Abstract: The media production element combines media content from a plurality of streaming electronic devices when they are registered to be within the same streaming event. The media production element can produce a combined live video stream or a combined media production using selections and combinations of the streamed content provided by the multiple electronic devices. An electronic device participating in the uplink data streaming of the event can transmit data segments to the media production element in real-time, and it can also store data segments locally. A network assistance device or media production element can request a non-real time stored data segment from the electronic device.
