A media packaging and distribution system that allocates each of a plurality of first instructions from an instruction queue to a corresponding first worker based on an instruction type and a priority level. Each of the plurality of first workers reads a first manifest data, which is non-ingested metadata, of at least one of a plurality of live input streams or a second manifest data of a plurality of pre-encoded media assets from locations of corresponding input manifests. Further, a second instruction from a plurality of second instructions is allocated to a second worker. The second worker inserts a next manifest segment to a disparate live output stream manifest upon reading a manifest metadata ingested into a manifest metadata storage system. Accordingly, the plurality of disparate live media output stream manifests is generated for a plurality of channels based on the disparate live output stream manifest.

A server system includes a database for storing data, a memory device for storing data selected from the data in the database, and a processing device that selects data from the database, stores the selected data in the memory device, and transmits over a communication network an availability signal to a client, the availability signal including an identifier of the selected data and indicating that the selected data is stored in the memory device and is available to be accessed by the client.

In one embodiment, a method includes receiving a stored copy request indicating data and including a request identifier, scheduling publication of the data to an object store, and sending a subscription request indicating the data and the request identifier to the object store. In another embodiment, a method includes receiving a publication request indicating data to be copied, wherein the publication request is a recording request indicating a channel and a timespan, receiving one or more subscription requests for the data, receiving the data, and generating a copy of the data for each subscription request.

A technique for managing data objects in a storage cluster includes splitting a media data object into multiple portions at boundaries within the media data object. The technique further includes transforming the portions of the media data object into segments that provide individually processable units and distributing the segments among multiple computing nodes of the storage cluster for storage therein.

Techniques described herein relate to a method for distributed data management. The method may include obtaining, by a data management agent of a data host and from an application executing on the data host, a request to access data; obtaining, by the data management agent, an information set associated with the data; making a determination, by the data management agent, that at least a portion of the data is not ready to be used by the application; and performing, by the data management agent and based on the determination, a data preparation action set.

The disclosed computer-implemented method includes determining that incoming media item requests are to be skewed from a random distribution among server nodes, using a random distribution algorithm, to a directed distribution among the server nodes. The method then includes identifying, in a loading assignment, which media items are to be loaded onto specific server nodes to produce the directed distribution of media item requests. The method next includes preloading the identified media items onto the server nodes according to the loading assignment and receiving media item requests for the preloaded media items. The method then includes routing the received media item requests to the server nodes using the random distribution algorithm, where the random distribution algorithm is skewed to the directed distribution based on the preloading of the media items according to the identified loading assignment. Various other methods, systems, and computer-readable media are also disclosed.

Systems and methods are described to address shortcomings in the conventional network storage systems via novel techniques to store offsets of a recorded program in a network digital video recorder (DVR). Storing offsets of a recorded program may be beneficial to users that would like to record media content that is broadcast either prior to a start time of a program, or media content that is broadcast after an end time of a program. This feature may be useful when start times and end times of a program are variable (e.g., in the case of sporting events, or other real-time events). This feature may also be useful for recording content of interest that is scheduled for broadcast prior to a start time of or after an end time of the program.

While a first playback device is a member of a synchronous media playback group with a second playback device using a first media playback protocol, and after a particular playback setting is enabled using the first media playback protocol, the first playback device receives, from a media source device, a first media stream using a second media playback protocol. The first and second media playback protocols are incompatible. The first playback device determines that the particular playback setting is enabled and that the synchronous media playback group includes the first playback device and the second playback device. Subsequently, the first playback device (i) generates a second media stream based on the received first media stream, the second media stream including information for synchronous playback with the first playback device, and (ii) transmits, to the second playback device, the second media stream using the second media playback protocol.

Video on demand is orchestrated between systems by linear program (LP) based multimedia storage and retrieval. An LP based storage and retrieval system can partition multimedia data into an integral number of segments. Further, the LP based storage and retrieval system can store a first amount of the integral number of segments in a storage device of storage devices of a storage network in response to a determination that a storage size of the storage device satisfies a first condition with respect to the first amount of the integral number of segments. Furthermore, such system can store a segment of a second amount of the integral number of segments in a remote storage device of the remote storage devices in response to a determination that the segment satisfies a second condition with respect to a defined number of remote storage devices of the storage devices that have stored the segment.

Systems, devices, apparatuses, components, methods, and techniques for providing media content to a media playback system are provided. The techniques provide for determining whether a playback system is connected, or otherwise associated with, a playback device suitable for 3D audio playback. Upon determining that a playback system is or is not connected or otherwise associated with a playback device suitable for 3D audio playback, audio content in a corresponding format may then be transferred and/or played by a requesting system. In some examples, one or more filters may be applied to requested audio content to compensate for determined user head movement and/or to create simulated 3D audio from generic two-channel recording.
