Abstract: A method for providing a unique remote experience of a live event includes receiving in near real time at a headend processing system from a control center at an event location raw media data captured at a live event occurring at the event location. Copies of the raw media data from the headend processing system are disseminated in near real time to a plurality of server nodes of a geographically distributed content delivery network connected together via communication network. The raw media data is processed to produce one or more customized presentations of the live event in the form of streaming audio/video (A/V) files of one or more subsets of the raw media data pursuant to one or more data structures corresponding, respectively, to one or more subscriber accounts. The streaming A/V files are transmitted over a communication network to one or more respective subscriber presentation devices.

Abstract: During a live event, one or more cameras capture audiovisual data and provide the captured audiovisual data via one or more data feeds. The one or more data feeds are downscaled to a lower resolution and presented on a graphical user interface (GUI). One or more production selections are made related to the one or more data feeds via the GUI by a video editor to create a broadcast stream of the live event. A presentation track is created based on the one or more production selections made by the video editor. The presentation track is streamed to a user's device as a data feed and is used to re-create the broadcast stream of the live event. The user's device, based on the presentation track, obtains media streams from the one or more cameras at the captured resolution.

Abstract: Techniques are described herein for optimizing the presentation of content through obtaining viewership metrics, generating multiple renditions of presentations of content, and selecting optimized renditions of content. One aspect includes associating a request for viewership metrics with a presentation of content, publishing the presentation of content, and receiving information of the viewership metrics associated with the presentation. Another aspect includes copying a presentation of a content item, creating a second presentation of the content item for publishing over one or more channels, and linking the presentation of the content item to the second presentation of the content item, such that a change to one propagates to the other of the presentation of the content item or the second presentation of the content item. In yet another aspect, a content rendition may be selected for presentation based on performance of the rendition out of multiple renditions in an auction.

Abstract: The disclosure relates to a method, apparatus, readable medium, and electronic device for live stream interaction. The method includes: in accordance with displaying of a first control at a first target position of a live stream interface, obtaining a first duration during which a user watches the live stream interface; in accordance with a determination that the first duration is greater than or equal to a first predetermined duration threshold, switching the first control to a second control, and displaying the second control at a second target position of the live stream interface; and in response to a first operation command performed by the user on the second control, allocating a virtual resource to the user. In this way, interaction modes of a live stream room are enriched, and an activity level of the live stream room can be improved.

Abstract: A system interconnects multiple client devices over a network. A local group of the client devices is located at a live event and a remote group is located remote from the live event. Each client device of the local group is a potential source of a live stream which, when rendered by another client device, causes display of a vantage point of the live event. The system dynamically updates a subscription list to include an indication of any client device of the local group that is actively live streaming and remove an indication of any client device of the local group that terminated live streaming. The system can enable selective access to any live streams of any client device of the updated subscription list and disable access to any live streams of any client device removed from the updated subscription list.
