Thus, while the arbitrated group voice communication paradigm with sequential floor control is dominant in critical communications, especially public safety voice systems, the optimal method for distributing group video information is less obvious
Moreover, although many video conferencing systems and methods are known in the art, none of these conventional systems can meet the needs and demands of users in a group communication environment

A method for managing distribution of video includes receiving a plurality of video data streams from a plurality of video data source devices associated with a group. Each video data stream includes a plurality of video frames and a plurality of metadata fields. The video data streams is parsed to extract the video frames and information comprising the plurality of metadata fields. A common group metadata stream is generated which includes metadata information from the plurality of metadata fields. The common group metadata stream is communicated to user equipment devices (UEDs) operated by users who may have an interest in video streams. Upon receipt of a demand for a first user video stream based on information contained in the common group metadata stream, a first user video stream is generated and communicates to a UED.
Description
technical field [0001] Configurations of the present invention relate to public safety communication systems, and more particularly to video distribution in group-based communication environments. Background technique [0002] In public safety voice systems, it is common to divide users into chat groups. Within each group, a single speaker "gets the floor" while the other members of the group hear that speaker at approximately the same time. These systems work well for voice communications, but similar progress has not been made in determining optimal systems and methods for distributing video content. [0003] It should be appreciated that people process speech information in a significantly different manner than the way they process visual information. In layman's terms, one might observe that people are used to listening to one speaker at a time. In formal committee meetings, the chair or facilitator adjudicates between competing requests for the floor, and sequential ...
