Updating object subscriptions based on trigger events is described. An indication of a trigger event, associated with an object, can be received from a client of a user. The object can be associated with current object data that is stored in a storage area of a subscription management system. The storage area can maintain the current object data for at least the object and a subscription list for client(s), wherein the subscription list for each of the client(s) comprises object identifiers corresponding to subscribed objects for each of the client(s). Based at least partly on receiving the indication of the trigger event and determining that the trigger event is associated with a modification to a subscription, the subscription list can be updated to generate an updated subscription list for the client and current object data for the subscribed objects identified within the updated subscription list can be provided thereto.

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for generating search queries in response to obtaining audio samples on a client device. In one aspect, a method includes the actions of i) receiving audio data from a client device, ii) identifying specific content from captured media based on the received audio data, wherein the identified specific content is associated with the received audio data and the captured media includes at least one of audio media or audio-video media, iii) obtaining additional metadata associated with the identified content, iv) generating a search query based at least in part on the obtained additional metadata, and v) returning one or more search results to the client device, the one or more search results responsive to the search query and associated with the received audio data.

An adaptive streaming server, a method, and a system are described herein that create a content stream to be delivered to one or more clients by segmenting the content into data structures which are stored in random access memory (volatile storage) rather than segmenting the content into segment files which are stored on a disk or database (non-volatile storage).

An illustrative multi-access server receives a request from a client system, the request indicating a requested rendering operation. The multi-access server also accesses input data from an asset data source. The multi-access server performs a rendering pass on the input data, the rendering pass performed in accordance with the requested rendering operation to generate a render pass output dataset. The render pass output dataset is representative of a renderable image depicting image content in a first form having limited quality or detail. The render pass output dataset is also configured for use in generating fully-rendered image data that depicts the image content in a second form having additional quality or detail beyond the limited quality or detail of the first form. Corresponding methods and systems are also disclosed.

Systems and methods are described for performing adaptive bitrate (ABR) streaming. A user device may request a segment of a first version of a plurality of versions of a content asset from a content provider, and may receive the segment. An estimated time to receive a second segment of a second version of the content may be determined based on metrics associated with receipt of the segment of the first version and in a manner that takes into account latency with the network, such that a determination whether to switch to a higher or lower bitrate version of a content asset during ABR streaming may be more accurately made.

A computer implemented method is provided for streaming media from a media server to a client web application running in a client web engine. The method involves, by the client web application, initiating a programmable network proxy in the client web engine. The method further comprises, by the programmable network proxy, intercepting a request from the client web application to retrieve the streaming media from the media server and/or intercepting a response comprising the streaming media from the media server. The method further includes, by the programmable network proxy, performing at least one of: i) injecting metadata into the intercepted request; ii) extracting metadata from the intercepted request; iii) injecting metadata into the intercepted response; and iv) extracting metadata from the intercepted response; and respectively forwarding the intercepted request to the media server and/or forwarding the intercepted response to the client web application.

Example embodiments provide systems and methods for replacing recorded media content. In an example method, at least one media content source is searched for a media content item recorded to storage of a first media content device. Based on the media content item being found at a first media content source of the at least one media content source, a recording of the media content item to storage of a second media content device is scheduled based on the media content item being recordable from the first media content source at the second media content device. Based on the media content item not being recordable from the first media content source at the second media device, the availability of the media content item is indicated to the second media content device.

Systems and methods for automatically generating top level index files for use in adaptive bitrate streaming in accordance with embodiments of the invention are disclosed. One embodiment of the method of the invention includes receiving a request from a playback device at a playback server, where the request identifies a piece of content, retrieving a list of assets associated with the identified piece of content using the playback server, filtering the list of assets using at least one predetermined criterion using the playback server, generating a top level index file describing each asset in the filtered list of assets using the playback server, and sending the top level index file to the playback device using the playback server.

Disclosed are a hypertext transfer protocol (HTTP) request transmission method and device. The HTTP request transmission method and device resolve a problem that data finally obtained through splicing is invalid because dividing an original HTTP request into a plurality of HTTP requests to pull data from different content distribution network (CDN) servers may cause inconsistency of the pulled data. When an electronic device needs to download data from a plurality of CDN servers, an overlapping range may be designed for byte ranges allocated to the different CDN servers. This means that the electronic device downloads data in the overlapping range from all the different CDN servers. Therefore, this part of data is used to check consistency of the data pulled from the different CDN servers. When determining that the data pulled from the different CDN servers is consistent, the electronic device may splice the data to obtain finally required data.

A video processing method is provided. In the method, a video bit stream is obtained. Configuration information of the video bit stream is determined. The configuration information includes reference image information. The reference image information indicates (i) whether a video track corresponding to the video bit stream includes a reference image and (ii) whether the video track requires reference to the reference image. The video bit stream and the configuration information are encapsulated to obtain the video track.
