One embodiment sets forth a technique that includes receiving a request for a range of data included in an encoded version of the media title that is stored across a set of files. The technique also includes determining, based on a file extent index, one or more files included in the set of files, wherein the file extent index maps an identifier for each file in the set to a given range of data that is stored in the file and included in the encoded version. The technique further includes retrieving the range of data from the file(s), wherein at least a portion of the retrieved range of data falls within the given range of data that is stored in each of the one or more files, and transmitting the range of data in a response to the request.

The present disclosure is related to systems and methods for storing data. The method includes obtaining a streaming data file including a first set of data frames. The method includes, in response to determining that the streaming data file satisfies one or more conditions, generating a hole frame storing an offset address of the streaming data file, and establishing a target streaming data file by adding a second set of data frames into the streaming data file based on the hole frame.

Methods, apparatus, systems, storage media, etc., to perform media monitoring for mobile platforms using messaging associated with adaptive bitrate streaming are disclosed. An example media platform disclosed herein is to detect an adaptive bitrate streaming uniform resource locator (URL) in an outgoing message to be sent by the mobile platform to stream media in accordance with an adaptive bitrate streaming protocol, and associate the adaptive bitrate streaming URL with a time value. The disclosed example media platform is also to transmit the outgoing message to a first server to cause the media to be streamed to the mobile platform, and transmit the adaptive bitrate streaming URL and the time value to a second server different from the first server to cause a media impression associated with the mobile platform to be monitored.

Methods and system for providing content are disclosed. One method can comprise receiving a request for data at a first time, wherein the data comprises a first time duration, determining a buffer size based upon the first time duration, and determining a playback window based upon the determined buffer size and the first time. The method can also comprise synchronizing presentation of content on a plurality of devices.

Disclosed are a method, an apparatus and a smart mobile terminal for editing a video. The method includes: acquiring an editing instruction to be executed of a user; selecting frame images which indicate a duration of a video segment in a preset showing area based on the editing instruction; storing the video segment in a preset second storage area; storing a reserved video segment in a preset first storage area; rendering the frame images by invoking a preset rendering script for highlighting the frame images in the showing area; retrieving frames of the reserved video segment sequentially based on a preset first time span; determining scaled frames based on a preset scaling proportion and the frames; and arranging the scaled frames in the showing area sequentially in an order of retrieving for displaying frame images which indicates a duration of the reserved video segment in the showing area.

A media guidance application may determine a length of a portion of a media asset that the user has missed and compare the length with a threshold length. If the length is greater than the threshold length, the media guidance application may generate a first summary of the missed portion of the media asset based on segments of the missed portion of the media asset that are of a first importance. If the length is not greater than the threshold length, the media guidance application may generate a second summary of the missed portion of the media asset based on segments of the missed portion of the media asset that are of the first importance and the second importance. The media guidance application may generate for display the summary.

A method and an apparatus for retrieving teleplay content is disclosed. The method includes: generating basic summary information corresponding to each teleplay based on basic information of entities of each teleplay; generating episode summary information corresponding to each episode of each teleplay based on episode data of each episode of each teleplay; establishing a teleplay graph database based on the basic summary information corresponding to each teleplay and the episode summary information corresponding to each episode; and feeding a playing portal for a target episode of a target teleplay corresponding to teleplay search information back to a user based on the teleplay graph database.

Aspects of the disclosure provide methods, apparatuses, and non-transitory computer-readable mediums for receiving media data of media content. One apparatus includes processing circuitry that receives a media presentation description (MPD) file and a session-based description (SBD) file. The processing circuitry determines whether the SBD file includes a starting time attribute indicating a starting time of an SBD timeline of a session. The processing circuitry determines the starting time of the SBD timeline based on the SBD file in response to the SBD file including the starting time attribute. The processing circuitry determines the starting time of the SBD timeline based on the MPD file in response to the SBD file not including the starting time attribute.

Disclosed are multiple methods and multiple apparatus e media data, and multiple methods and multiple apparatus for media data transmitting, media data processing, reference picture request processing and reference picture specifying. By means of the method to produce media data, the method for media data transmitting, and the method for media data processing, the synchronization and correct processing and transmission of bitstreams are ensured on the basis of dependency relation between video layer bitstream and library layer bitstream, and correct bitstream is highly efficiently provided to a decoder. By means of the method for reference picture request processing and reference picture specifying, a current picture is provided with a library picture set in which the library picture does not belong to the random access segment to which the current picture belongs and the previously most adjacent random access segment, and correct decoding of the current picture is ensured and repeated downloading of library pictures is avoided, thus ensuring the correct decoding and highly efficient transmission of a bitstream produced by library-based video coding method, and increasing transmission efficiency and storage efficiency.

Methods, apparatus, systems, and articles of manufacture are disclosed to generate synthetic respondent level data. Example apparatus disclosed herein include means for generating a synthetic panel corresponding to a duration of time, the means for generating the synthetic panel to: generate a transition matrix corresponding to a first sub-duration of the duration of time and a second sub-duration of the duration of time; generate, based on the transition matrix, a plurality of synthetic panelists and associated viewing data; remove first ones of the synthetic panelists associated with one or more weights that do not satisfy a threshold to generate the synthetic panel corresponding to the duration of time, the synthetic panel representative of audiences of media presented by a plurality of media devices during the duration of time; and generate synthetic respondent level data based on the viewing data associated with remaining second ones of the synthetic panelists.
