A virtual set-top box (vSTB) for executing a middleware component, designed originally for use with the physical STB, including emulating hardware capabilities of the physical STB to process IPTV content received over a connection for presenting the IPTV content on a display of the electronic device.

In general, in an aspect, versions of representations of segments of a media item are received and temporarily stored on a media playing device. The segments have a sequence. The temporarily stored versions are used in sequence to present at least part of the media item to a user. One or more other versions of representations of segments of the media item are also received and persistently stored on the media playing device. The one or more persistently stored other versions are used to enhance the presentation of at least part of the media item to the user.

A data storage device and method for real-time data locking in surveillance storage are provided. In one embodiment, a data storage device is provided comprising a memory and a controller. The controller is configured to receive an image of an object of interest from a host; receive a video stream from the host; and as the video stream is being received from the host, determine whether the object of interest is present in the video stream. Other embodiments are provided.

A method includes detecting a memory error associated with a memory device of a storage unit of a set of storage units that is storing a set of encoded data slices, the storage unit services encoded data slice access messages from a processing unit, and the detecting occurs while attempting to access one or more of: a read threshold number (R) of encoded data slices, a decode threshold number (D) of encoded data slices needed to reconstruct the data segment, or a write threshold number (W) indicating a number of encoded data slices that must be accurately stored. The method further includes identifying an error descriptor code based on the detected memory error. The method further includes determining to perform an action based on the error descriptor code and executing the action to produce an action result.

A content streaming system and methodology for facilitating the management of content streaming. A video packaging and origination service requests streaming content that is organized according to content segments. Individual content segments will be encoded according to a plurality of encoding profiles and generated by different encoders. The video packaging and origination service utilizes synchronization information provided to the encoders to select individual encoded content segments responsive to the request for streaming content.

Example techniques relate to cloud queue tombstones. An example implementation may involve a computing system receiving instructions to remove a particular media item from a playback queue. Based on the instructions, the computing system removes the particular media item from the playback queue and adds, to the playback queue, a tombstone indicator indicating that the particular media item has been removed from the playback queue. The computing system receives, from the media playback system, a request for a window of one or more media items from the playback queue. Based on the request, the computing system sends, to the media playback system, data representing a particular window of media items from the playback queue, wherein the particular window includes the tombstone indicator. The computing system detects a given tombstone removal trigger from among multiple tombstone removal triggers and based on the detecting, removes the tombstone indicator from the playback queue.

Methods and systems for managing data and/or operations on data are disclosed. A method can comprise receiving content from a first storage medium for playback. The received content can comprise a stored first portion of a transport stream. At least a portion of the received content can be caused to playback. A playback position of the at least a portion of the received content can be determined relative to a live position of the transport stream. If the determined playback position of the at least a portion of the received content is outside a predetermined threshold proximity to the live position, a second portion of the transport stream can be stored to the first storage medium. If the determined playback position of the received content is within the predetermined threshold proximity to the live position, the second portion of the transport stream can be stored to a second storage medium.

Systems and methods for managing the storage and delivery of recorded content in a network digital video recorder (DVR) system are disclosed. A plurality of requests to record a program may be received, wherein the program may comprise a plurality of segments. A segment from the plurality of segments may be determined to be copied to a first storage. A copy of the segment may be received from a second storage and a plurality of copies of the segment may be created in the first storage from the copy of the segment received from the second storage. The quantity of the plurality of copies of the segment may be equal to the quantity of the plurality of requests to record the program.

A method for processing a multimedia file is described. The method includes obtaining a source slice media file included in a source multimedia file, and obtaining, by processing circuitry of a transcoding device, a slice pre-processing result corresponding to the source slice media file, the slice pre-processing result indicating a storage address of an image area processing result of the source slice media file, in a pre-processing device. The method also includes obtaining, by the processing circuitry of the transcoding device, the image area processing result of the source slice media file from the storage address. Finally, the method includes processing, by the processing circuitry of the transcoding device, the source slice media file according to the image area processing result, to obtain a processed target slice media file.

The disclosed computer-implemented method includes accessing cluster hardware information that identifies at least two different types of storage media within a cluster and provides an indication of a respective amount of data throughput for each identified type of storage media. The method next includes accessing popularity information for digital content that is to be stored in the cluster. The popularity information indicates how often the digital content is predicted to be accessed over a specified future period of time. The method also includes allocating the digital content on the different types of storage media within the cluster according to the popularity information. Accordingly, digital content predicted to have higher popularity is placed on storage media types with higher throughput amounts, and digital content predicted to have lower popularity is placed on storage media types with lower throughput amounts. Various other methods, systems, and computer-readable media are also disclosed.
