Systems, methods, and computer program products to perform an operation comprising receiving a first set of search results including a first search result from a video service based on a first search string, extracting a set of attributes for the first search result based on a source code of the first set of search results, wherein the first search corresponds to a first video hosted on the video service, and upon determining that at least one attribute of the set of attributes for the first search result violates at least a threshold number of rules of a plurality of rules, storing an indication that the first video is a candidate for removal from the video service.

Hybrid storage of program recordings in a service provider network

A method of managing, by a service provider, a program stored within a service provider network. Multiple multimedia devices are in communication with the service provider network. In accordance with one embodiment, a method for managing, by a service provider, a program stored within a service provider network includes determining a first number of subscriptions for the program. If the first number of subscriptions is less than a first threshold, at least a portion of the program is transmitted to at least a first multimedia device having a subscription for the program and the program is removed from the service provider network.

Method and system for performing a contextual stitching operation on video data using a data processing unit

A method for processing video data is performed by a data processing unit (DPU). The method includes identifying, by the DPU of an edge device, a contextual stitching trigger event; in response to identifying the contextual stitching trigger event: identifying video data chunks, contextual metadata, indexing metadata, and authentication and authorization (AA) metadata associated with the contextual stitching trigger event; generating a virtual blob based on the video data chunks, contextual metadata, indexing metadata, and authentication and authorization AA metadata; making a first determination that a playback request is obtained from a user, wherein the playback request comprises user authentication information; and in response to the first determination: making a second determination that the user authentication information matches the AA metadata; and in response to the second determination; encoding the video data chunks into a single stream and initiating playback for the user.

POLICY BASED TRANSCODING

Methods and systems are disclosed for providing video content in response to requests in a content delivery system with more speed and efficiency. In some aspects, network monitoring devices may gather content specific and network performance metrics, from user devices and content delivery components, to provide input to a computing device for deciding whether to store or delete different versions of the same or different items of content. The decision may be based on a policy which may include a weighted score based on a combination of usage and network efficiency scores. In other aspects, methods and systems are provided to initially provide to a user device a stored version of a content item, and then switch, as needed, to a different version of the content item using on-demand transcoding.

DISTRIBUTED SURVEILLANCE SYSTEM WITH DISTRIBUTED VIDEO ANALYSIS

Video analysis in a distributed video management system in which video data from a given camera is sent to at least two distributed camera nodes for simultaneous processing of video data by the distributed camera nodes. In some examples, the respective camera nodes may execute video analysis modules that each apply a different video analysis module to the video data. Video data may, by default, be provided to a first camera node. In turn, upon detection of a trigger, video data may be provided to a second camera node. The trigger may be periodic or, for example, in response to metadata generated by the first video analysis module of the first camera node. In turn, versatile and robust video analysis may be performed by the distributed video management system.

PARAMETER BASED LOAD BALANCING IN A DISTRIBUTED SURVEILLANCE SYSTEM

A distributed video management system for video surveillance that allows for monitoring a camera allocation parameter and dynamic reallocation of video cameras to available camera nodes in response to detecting a change in the allocation parameter. As such, the system may provide for load balancing of the processing of video data from the video cameras with reference to the allocation parameter. The change in allocation parameter may be due to a number of potential contexts, including a change in availability of camera nodes, a change in the nature of the video data captured, a change in computational load, or other change that results in a change in allocation parameter. The allocation parameter may be continually monitored to allocate video cameras to camera nodes in the system for enhanced system performance in view of potentially changing conditions.

SELECTIVE USE OF CAMERAS IN A DISTRIBUTED SURVEILLANCE SYSTEM

A distributed video management system that allows for monitoring a camera allocation parameter and dynamic reallocation of video cameras to available camera nodes in response to detecting a change in the allocation parameter including selectively dropping at least one camera from the system based on a priority of the camera. The change in allocation parameter may be due to a number of potential contexts including a change in availability of camera nodes, a change in the nature of the video data captured, a change in computational load, or other change that results in a change in allocation parameter. The disconnection or “dropping” of a camera may be temporary in response to an increase in computational load on the system. The use of priority values of the cameras may allow for sufficient camera coverage to be provided by the system while maintaining processing of video data from higher priority cameras.

Methods and apparatus for initiating a playback pause operation on one device and resuming playback on another playback device

Methods and apparatus that support implementing a pause, e.g., of a broadcast, on a device, recording the paused program and resuming playback of the paused program on a device associated with a user's account, are described. The pause function allows a user to pause a broadcast on a device and initiate recording of the paused program, e.g., to network storage. The pause initiating device displays a pause indicator indicating that the program output has been paused. A user logging into the user's account from a device other than the device from which the pause was initiated is presented an opportunity to resume the paused playback. Playback is resumed from the pause point on the playback device from which a resume signal is received. Upon resumption of playback on a device other than the device from which the pause was initiated, the pause indicator on the pause initiating device is removed.

System and method for storing multimedia files using an archive file format
11212574 · 2021-12-28 · ·

Techniques and mechanisms described herein facilitate the storage of digital media recordings. According to various embodiments, a system is provided comprising a processor, a storage device, Random Access Memory (RAM), an archive writer, and a recording writer. The archive writer is configured to retrieve a plurality of small multimedia segments (SMSs) in RAM and write the plurality of SMSs into an archive container file in RAM. The single archive container file may correspond to a singular multimedia file when complete. New SMSs retrieved from RAM are appended into the archive container file if the new SMSs also correspond to the singular multimedia file. The recording writer is configured to flush the archive container file to be stored as a digital media recording on the storage device once enough SMSs have been appended by the archive writer to the archive container file to complete the singular multimedia file.
