A system is provided for publishing a disparate live media output stream manifest that includes media segments corresponding to key events. A live production and playout system of disparate sub-systems is synchronized to a reference clock. A timecode from the reference clock is used as a reference time to log content related to key events that occur within the live production and playout system. A live event logging system is synchronized to the reference clock same as the live production and playout system. Based on location of the live event logging system, a time offset is introduced to compensate for a delay. When delay is variable, the reference clock is decoded from a live input stream to associate each key event with a corresponding timecode. Based on a programming schedule comprising the key events that occurred in the live input stream, the disparate live media output stream manifest is published.

A method is disclosed for protecting a multimedia content distributed by a content service to a user device, the multimedia content being related to a live event, wherein the method comprises, during the live event: identifying a significant segment of the live event; generating a trigger signal associated with the significant segment; at the user device, on the basis of the trigger signal, generating a marking comprising information identifying the user device; and, at the user device, applying the marking to a selected portion of the multimedia content, the selected portion corresponding to the significant segment of the live event.

This application discloses a virtual live streaming method and apparatus, a device, and a storage medium. The method includes: acquiring a live text content which is a text content broadcast by voice by a virtual character in a virtual live stream; segmenting the live text content to obtain text segments that are sequentially arranged; acquiring a live broadcast data packet of each of the text segments following a sequence of the text segments, the live broadcast data packet comprising mouth shape data corresponding to the each of the text segments and being used for determining a mouth shape of the virtual character corresponding to the text segment; and performing screen rendering based on the live broadcast data packet to obtain a live screen for the virtual live streaming, the live screen comprising the virtual character who expresses the each of the text segments with a corresponding mouth shape.

A digital content storage and delivery system (DCSDS) includes a network interface to communicate data between the DCSDS and a destination device via a network data communication link having limited bandwidth. An input interface receives digital content for handling by the DCSDS. A storage architecture stores recorded video content on behalf of subscriber end users for on-demand playback via the network data communication link, and it caches live streaming video content for distribution via the network data communication link. The DCDS may monitor bandwidth usage of the network data communication link, determine current bandwidth demand for playback of recorded video content stored at the storage architecture, and reserve at least some of the limited bandwidth of the network data communication link to satisfy the determined current bandwidth demand. The available bandwidth is allocated to support distribution of live streaming video from the DCSDS.

A stereoscopic production solution, e.g., for live events, that provides 3D video asset distribution to multiple devices and networks is described. In some embodiments, live or recorded 3D video content may be accessible by different service providers with different subscribers/users and protocols across a network of the content provider. A first video signal corresponding to a first video feed for one eye of a viewer may be received and a second video signal corresponding to a second video feed for the second eye of the viewer may be received. The first video signal and the second video signal may be encoded. The encoded first video signal and the encoded second video signal may be transmitted independently over a network. The two video signals may be received and frame synced at an off-site location for eventual rendering to a display device.

A non-transitory computer readable medium storing computer executable instructions which, when executed by one or more processors, cause the one or more processors to perform a process including generating avatar information relating to an avatar expression or pose based on streamer data indicating a facial expression or pose of a streamer; acquiring gift information concerned with a gift of an object that is provided from a viewer to the streamer; determining whether the gift information satisfies a predetermined condition; in a case that the gift information is determined to satisfy the predetermined condition, rendering an avatar facial expression or pose using a predetermined facial expression or pose corresponding to the predetermined condition; and in a case that the gift information is determined to not satisfy the predetermined condition, rendering the avatar facial expression or pose using the avatar information generated based on the streamer data.
