DYNAMIC CREATION OF LOW LATENCY VIDEO STREAMS IN A LIVE EVENT
A method for creating a low latency DASH (LL-DASH) video stream from a Low latency HLS video stream (LL-HLS) is provided. The LL-HLS video stream corresponding to a live event is retrieved. The LL-HLS video stream is converted to a LL-DASH video stream. This conversion of the LL-DASH stream from the LL-HLS stream provides reformatting without encoding of the LL-DASH stream.
Method for audio and video just-in-time transcoding
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.
METHODS AND SYSTEMS CONFIGURED TO MANAGE VIDEO TRANSCODER LATENCIES
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.
IMMERSIVE MEDIA ANALYZER FOR REUSE OF SCENE ASSETS
Optimizing media distribution of a media steam performed by at least one processor, is provided, including: receiving immersive media data for an immersive presentation from a content source; acquiring asset information corresponding to media assets in a set of scenes included in the immersive media data; analyzing characteristics of the media assets, from the asset information, used in the set of scenes to determine whether a respective media asset is unique among the media assets; and generating metadata information that uniquely identifies the respective media asset for reusing the respective media asset in the set of scenes, based on determining that the respective media asset is not unique among the media assets in the set of scenes included in the immersive media data for the immersive presentation.
System and device for remote automatic editor
A system for remote editing of a file includes a database including a plurality of source media content files and a content host configured to generate a first proxy for at least a portion of a first one of the source media content files, the first proxy including data sufficient to enable a remote user device to identify a portion of content of the first source media content file to be included in a generated clip, the content host configured to receive from the remote user device a request to create the generated clip from the first source media content file, the request indicating parameters defining, based on the data in the first proxy, the portion of the first source media content file to be included in the generated clip, the content host configured to create the generated clip based on the parameters indicated in the request.
SYSTEM FOR HIGH PERFORMANCE ON-DEMAND VIDEO TRANSCODING
The Cloud-based Video Streaming Service (CVSS) architecture is disclosed to transcode video streams in an on-demand manner. The architecture provides a platform for streaming service providers to utilize cloud resources in a cost-efficient manner and with respect to the Quality of Service (QoS) demands of video streams. In particular, the architecture includes a QoS-aware scheduling method to efficiently map video streams to cloud resources, and a cost-aware dynamic (i.e., elastic) resource provisioning policy that adapts the resource acquisition with respect to the video streaming QoS demands. Simulation results based on realistic cloud traces and with various workload conditions, demonstrate that the CVSS architecture can satisfy video streaming QoS demands and reduces the incurred cost of stream providers up to 70%.
LOCALIZED CLOUD SERVICES FOR PRIVACY-ISOLATED CLIENTS
Various arrangements of a local cloud system for providing television services are presented. A facility cloud host system may have a content service provider interface that is used to receive live television channel streams from a television content service provider. The local cloud system may have a transcoder that transcodes the live television channels into a format to be transmitted locally to client devices. The local cloud system may provide access to recorded content from a remote master cloud host.
METHOD, SYSTEM, AND APPARATUS FOR MULTIMEDIA CONTENT DELIVERY TO CABLE TV AND SATELLITE OPERATORS
Systems, methods, and computer-readable media for delivering multimedia content from the cloud to cable operators are disclosed. A device located at the cable headend or implemented in the cloud can receive a request for at least one media stream for playback on a broadcast media channel. Content corresponding to a plurality of multimedia files in the media stream can be obtained from the internet or a cloud based service. The content can be used to generate the multimedia files in a format that is compatible with the cable operator. The multimedia files can be used to assemble the at least one media stream which can be provided to the cable operator for broadcast on the broadcast media channel.
Method To Insert Program Boundaries In Linear Video For Adaptive Bitrate Streaming
Aspects of the subject disclosure may include, for example, a system for indicating a program boundary in an adaptive bitrate media stream, where the system includes a memory and a processor that performs operations including generating multiple transcoded media output streams of different bit rates from an input linear media stream, fragmenting the multiple transcoded media output streams into chunks, detecting a program boundary in the input linear media stream, and supplying a program change indicator in a manifest file for implementing program change features in mobile communication devices. Other embodiments are disclosed.
Information processing device, information processing method, and program
The present technology relates to an information processing device, an information processing method, and a program, which enable processing to be performed by absorbing a protocol difference when data is exchanged using different protocols. A first processing unit that processes data with a first device that performs identification of content; and a second processing unit that processes data with a second device that performs reproduction of content, and processes data with the first processing unit, are provided. Identification of content is performed based on ACR (Automatic Content Recognition), for example, the first device is an ACR server, and the first processing unit is able to work as an ACR client that communicates with each of a plurality of ACR servers that performs ACR using a different protocol. The present technology is applicable to a protocol conversion gateway.
