A method and system are described wherein a terminal sends, to a server, a video request message that includes an identifier of a virtual reality (VR) video. The VR video comprises N sub-bitstreams. The terminal receives a video response message sent by the server. The video response message indicates multicast addresses respectively corresponding to the N sub-bitstreams, and the terminal determines a target sub-bitstream based on a current field of view of a user, and obtains the target sub-bitstream based on a multicast address corresponding to the target sub-bitstream. The multicast address is one of the multicast addresses, and the target sub-bitstream comprises at least one sub-bitstream of the N sub-bitstreams.

In one example, a method includes monitoring a delivery of an item of multimedia content to a first user endpoint device in a first stream of data, monitoring a delivery of the item of multimedia content to a second user endpoint device in a second stream of data, consolidating the stream of data and the second stream of data into a third stream of data, sending an first instruction to a source of the first stream of data and a source of the second stream of data to cease delivering the first stream of data and the second stream of data, and sending a second instruction to the source of the first stream of data and the source of the second stream to begin delivering the third stream of data to the first user endpoint device and the second user endpoint device.

A media flow transport security manager of a hybrid cloud-based media production system having a network orchestrator and an extensible resource manager (ERM) includes a firewall communicatively coupled to a computing platform having a hardware processor and a memory storing a security software code. The hardware processor executes the security software code to communicate with the network orchestrator to identify multicast production media flow(s) for processing in a cloud-based virtual production environment, and to communicate with the ERM to obtain an identifier of each cloud-based resource used for processing cloud production media flow(s) corresponding to the identified multicast production media flow(s). The hardware processor also executes the security software code to receive an alert that the cloud production media flow(s) have been processed to generate corresponding post-production cloud media flow(s), and to route, using the obtained identifier of the cloud-based resource(s), the post-production cloud media flow(s) through the firewall.

Software defined network orchestration to manage media flows for broadcast with public cloud networks is provided by identifying a media flow at a media production facility for multicast transmission; registering the media flow to a registration database; migrating the media flow from multicast transmission to unicast transmission; transmitting the media flow to a public cloud network facility; and updating the registration database with a location of the media flow in the public cloud network facility. Once registered, a media flow management system allows any authorized device to request for a media flow; and in response locates the media flow based on a registration database indicating a location of the media flow (whether in the public cloud network facility, on a common carrier, or in a production facility); receives access to the media flow at the location; and allows the authorized device to consume the media flow.

A hybrid cloud-based media production system includes a facility extension platform having a hardware processor and a memory storing a software code. The hardware processor executes the software code to identify multicast production media flow(s) for processing in a cloud-based virtual production environment, to identify cloud-based resource(s) for processing one or more cloud production media flow(s) corresponding to the multicast production media flow(s), in the cloud-based virtual production environment, and to coordinate provisioning of the cloud-based virtual production environment with the identified cloud-based resource(s). The hardware processor also executes the software code to align, using a cloud permissible timing protocol, the timing of the cloud production media flow(s) in the cloud-based virtual production environment, and to process the cloud production media flow(s) in the cloud-based virtual production environment using the identified cloud-based resource(s).

An extensible resource manager (ERM) of a hybrid cloud-based media production system includes a computing platform having a hardware processor and a memory storing a resource management software code. The hardware processor executes the resource management software code to communicate with a network orchestrator of the hybrid cloud-based media production system to identify multicast production media flow(s) for processing in a cloud-based virtual production environment, to identify cloud-based resource(s) for processing cloud production media flow(s) corresponding to the multicast production media flow(s), in the cloud-based virtual production environment, and to determine whether a license exists for the identified cloud-based resource(s). The hardware processor also executes the resource management software code to obtain the license when the license does not exist, and to provision, after obtaining the license or in response to determining that the license exists, the cloud-based virtual production environment with the identified cloud-based resource(s).

Provided are a system and method for publishing a disparate live media output stream manifest that includes one or more media segments corresponding to key events. The system comprises one or more processors that generate a programming schedule, based on a synchronization of one or more disparate sub-systems in the system, includes one or more key events that occurred from a starting point until a current live point in a live input stream. Further, a reference clock provides a reference time to synchronize the one or more disparate sub-systems. Based on the programming schedule, one or more processors insert the current live point and one or more media segments corresponding to the one or more key events that occurred prior to the current live point included in a live input stream manifest into a disparate live media output stream manifest, which is further published based on the insertion.

Aspects of the subject disclosure may include, for example, a method comprising encoding, by a server comprising a processor, media content to generate a plurality of media content files each having a filename and a uniform resource locator. The method also comprises receiving a channel request from a client media processor and generating a playlist. The playlist is mapped to the requested channel, and includes a filename and uniform resource locator for a personalized content file that is not included in the media content files. The method further comprises receiving a file request from the client media processor in accordance with the playlist, multicasting the plurality of media content files so that the client media processor receives the plurality of media content files, and delivering the personalized content file to the client media processor to enable presentation of personalized content in accordance with the playlist. Other embodiments are disclosed.

In synchronizing a playback of recorded media with a live media stream, a server streams live media to each of a plurality of participant devices at a normal rate. The live media stream is recorded and stored as the recorded media stream. When the server receives, from a given participant device of the plurality of participant devices, a request for playback after a pause at or a rewind to a specified location in the live media stream, the server calculates a playback rate to play the recorded media stream starting at the specified location. The playback rate is calculated such that a playback of the recorded media stream synchronizes with the live media stream at a target location or at a target time. The recorded media stream is then caused to play at the given participant device at the playback rate starting at the specified location.
