The described technology is generally directed towards coordinating the generation, validation and enabling of content selection graphs in an in-memory content selection graph data store. When a set of content selection graphs is requested, a coordinator starts the generation of the relevant graphs. Upon successful generation, the coordinator starts a validation of the generated graphs against rules for the nodes/response data in the graphs. If the generated graphs pass validation, the coordinator enables the graph set for use in an in-memory cache, whereby when a request to return content selection data is received, an active graph that corresponds to the request and the current time is accessed to obtain and return the response data as the requested content selection data.

Systems, apparatuses and methods may provide for technology that sends a first message via an input output (IO) link, wherein the first message includes a first rendering asset and an identifier (ID) associated with the first rendering asset. The technology may also exclude a second rendering asset from a second message in response to the ID being shared by the first rendering asset and the second rendering asset and send the second message via the IO link, wherein the second message includes the ID. In one example, the ID is a hash ID.

A new architecture of a distributed video production system is suggested. The distributed video production system enables distributed execution of one or more workflows that are operated by one or more operators at the same time. The present disclosure suggests mechanisms for synchronizing workflows and data streams within the distributed video production system. A workflow orchestrator is aware of all workflows currently executed on the distributed video production system and selects the required processing resources. A run time orchestrator ensures that the blocks are available for processing by controlling the receiving broadcast functionality such that it requests the block only after it is available by taking into account a network delay.

Aspects of the subject disclosure may include, for example, receiving, from a streaming application, a listing of media content items provided by the streaming application to a first device of a first user, determining a priority set of the media content items of the listing of media content items according to relative demand profiles of a plurality of media content items, for each priority media content item of the priority set of the media content items, providing the priority media content item to an edge server of a set of edge servers accessible to the first device, updating edge server location information associated with the priority media content item, and providing the edge server location information to the streaming application. Other embodiments are disclosed.

Systems, methods, and devices of the various embodiments disclosed herein may provide a protocol and architecture for decentralization of content delivery. Various embodiments may provide a client based method for content delivery from content delivery networks (CDNs) via tiered caches of content hosted by Internet Service Providers (ISPs). In various embodiments, content delivery protocol (CDP) messages may enable clients to discover local cache network topologies and request content from a CDN based on a discovered local cache network topology. In various embodiments, security may be provided for the content delivery by the use of key encryption and/or file hashing.

A method for streaming an audio-video file can include: receiving a request for a playback segment of the audio-video file in a rendition from a computational device; in response to identifying absence of the playback segment in the rendition from a rendition cache and identifying absence of an assignment to transcode the playback segment in the rendition: assigning a worker to transcode the playback segment in the rendition. The method can also include, at the worker: identifying a subset of mezzanine segments in the set of mezzanine segments coinciding with a playback interval in the audio-video file; and for each mezzanine segment in the subset of mezzanine segments: concurrently transcoding the mezzanine segment into a rendition segment in the rendition and transmitting the rendition segment coinciding with the playback interval to the computational device via a peer-to-peer stream; and storing the rendition segment in the rendition cache.

Apparatus and methods for content fragmentation, distribution, protection, and re-constitution within a content distribution network. In one embodiment, the apparatus and methods enable distribution of content fragments to edge nodes (which may include user or subscriber CPE), thereby enabling edge networks or membership groups to be established wherein content can be shared solely at the edge. In one variant, high data bandwidth, symmetric uplink/downlink, low latency PHY links (e.g., 5G NR-compliant wireless interfaces) between the edge nodes participating in the edge networks or membership groups are used such that particular quality of service/experience performance requirements can be met. Distribution of the fragments also advantageously enhances redundancy and security.

Systems and methods configured to detect and manage video transcoder latencies are described. A manifest is received and is used to request video segments included in a manifest playlist. A transcoder having an input and output is used to transcode video segments. A delta time for a first SCTE-35 marker between the transcoder input and the transcoder output is determined, where the delta time corresponds to a transcoder latency. A determination is made as to whether a corrective action needs to be taken with respect to the latency, and such corrective action is taken as needed. The corrective action may include a transcoder reset. The manifest may be a text file and may be in the form of an HLS or DASH manifest. Additionally, streaming latencies may be reduced by switching content distribution systems, increasing the number of edge systems distributing content to clients, and/or by increasing video cache memory.

A Reductive Edging device and computer program product. The Reductive Edging device has a processor, memory coupled to the processor and non-transitory instructions embedded in the memory that when executed by the processor causes the device to perform a method for reductive edging. The method includes, prior to sending a media segment to a client device, performing error de-emphasis operations and sending information associated with error de-emphasis.

A method and device for communicating video for synchronization between a portable wearable camera and a wireless hub device are described. The portable wearable camera may capture first video data. Also, the portable wearable camera may transmit the first video data to the wireless hub device via a video data channel, and may capture second video data. When the video data channel between the wearable camera and the wireless hub device is unable to support full resolution video playback, the portable wearable camera may store the second video data. Further, the portable wearable camera may receive a request via a control channel, from the wireless hub device, for the second video data, and may capture third video data. Further, the portable wearable camera may transmit, to the wireless hub device, the third video data via the video data channel and the second video data via the control channel.
