Video file storage prediction process for caches in video servers
11496809 · 2022-11-08 · ·

In some embodiments, a method receives a first set of video files at a node that delivers video files to client devices and receives a second set of video files. The second set of video files are predicted to be delivered by the node to a client device during a time period. The node receives a request for a video file from a client device and determines whether the video file is stored in the first set of video files and the second set of video files. When the video file is stored at the node, the node sends the video file from the first set of video files and the second set of video files. When the video file is not stored in the first set of video files and the second set of video files, the node sends a request for the video file to another node.

Method for sharing and searching playlists

A method for making a playlist available to the public, in which the playlist comprises user-defined descriptor information. The user-defined descriptor information is entered as free form text or prose.

Reception apparatus, transmission apparatus, and data processing method

A reception apparatus including reception circuitry and processing circuitry is provided. The reception circuitry is configured to receive control information and content, the control information including resource sharing information indicating whether a resource is shared among a plurality of applications. The processing circuitry is configured to control, based on the resource sharing information, sharing of the resource among the plurality of applications. The resource sharing information includes an identifier that is associated with the plurality of applications among which the resource is shared. The resource includes at least one file associated with at least one of the plurality of applications.

LIVE ROOM SETUP METHOD AND APPARATUS, ELECTRONIC DEVICE, AND STORAGE MEDIUM
20230098060 · 2023-03-30 ·

Provided are a method and an apparatus for creating a live room, an electronic device, and a storage medium. The method for creating a live room includes: receiving a trigger instruction of a preset creation identifier; acquiring, according to the trigger instruction, live information associated with the preset creation identifier; and sending the live information to a server such that the server creates a target live room based on the live information.

SYSTEMS AND METHODS FOR DYNAMICALLY SYNCING FROM TIME-SHIFTED FRAME TO LIVE STREAM OF CONTENT
20230099433 · 2023-03-30 ·

Systems and methods for skipping a presentation of a portion of segments to catch up to live based on a priority level value is disclosed. For example, a streaming application generates a content item for live streaming where the content item comprises a plurality of segments. In response to determining that playing of the content item lags behind the live streaming of the content item, the streaming application identifies a duration of lag and determines a priority threshold based on the lag. Based on a manifest which includes priority level information, the streaming application determines whether a respective segment needs to be cached. For example, if a priority level for a segment that is within the duration of the lag has a priority level that is higher the priority threshold, then the segment is stored in a cache from a respective network address and is played from the cache.

SYSTEMS AND METHODS FOR STREAMING MEDIA CONTENT DURING UNAVAILABILITY OF CONTENT SERVER

Systems and methods are described herein for streaming during unavailability of a content server. Upon determining that there are conditions indicating buffering issues during delivery of a media asset, a server determines a first group of devices suitable for receiving the media asset from the server and sharing the media asset on a peer-to-peer network. Then, the server determines a second group of devices suitable for receiving the media asset on a peer-to-peer network from a first group device. The server then determines groupings within which to share and receive the media asset. Next, the server transmits instructions to the devices in the first group to maintain in buffer and share certain portions of the media asset with the second group devices within their grouping. Finally, the server updates information detailing the media asset portions the devices are maintaining in buffer and sharing.

REDUCING DIGITAL VIDEO RECORDER STORAGE THROUGH REDUCED ENCODING OF CERTAIN PROGRAM PORTIONS
20230031929 · 2023-02-02 · ·

Systems, devices and processes reduce the amount of memory or disk space needed to store encoded video content used in adaptive video streaming by eliminating certain portions of the recorded program from one or more copies of the encoded program. Content occurring before or after a scheduled start of a program, for example, can be retained in only a subset of the encoded copies so that the program content is available to be streamed, but only at certain video qualities. Commercials or other less popular portions may also be eliminated in one or more encoded copies. By eliminating the less-likely-to-be-viewed portions of the content from some (but not all) of the encoded copies, the total amount of storage space needed to store the encoded program is reduced without compromising the ability to play back all portions of the recorded program.

SYSTEMS AND METHODS FOR REDUCING DIGITAL VIDEO LATENCY

Examples of the systems and methods described herein relate to reducing latency issues associated with playing online digital video on client devices. An example method includes: determining a likelihood that a user will trigger presentment of video content within a portion of digital content, and when the likelihood is determined to exceed a threshold, obtaining a video tag that identifies the video content or caching a portion of the video content prior to presentment of the video content.

Delay control method, delay control apparatus, terminal device and storage medium

Disclosed are a delay control method, a delay control apparatus, a terminal device and a storage medium. The delay control method comprises: initializing a cached data amount, and setting an initial delay threshold value; acquiring real-time cached data of a client, and determining a network status of the client according to same; and adjusting the current delay threshold value according to the network status. According to the delay control method, a network status of a user end is determined according to cached data of the user end, and a delay time is adjusted, so that in a large-scale live broadcast scenario, a player can dynamically control, according to the network status of each user, a delay time of each user end in real time, and improve the viewing experience of user.

Content caching services in satellite and satellite/IP content delivery systems
11609679 · 2023-03-21 · ·

Systems and methods are presented to facilitate caching of programming from broadcast and/or content streaming services to a user device for local playback. In addition, metadata can be provided to guide the user in selecting, caching, or playing the cachable content. In some exemplary embodiments, a receiver or other user device can automatically select the programming to be cached based on a user's historical topic interest and listening history. In some exemplary embodiments, the metadata can also include DRM information that can limit the ability of a user to playback the content, so as to comply, if necessary, with operative legal requirements related to usage of the content.
