The disclosure relates to a method of delivering a video frame. One implementation may involve spatially partitioning a video frame into a plurality of blocks, encoding at least one of the plurality of blocks of the video frame, and transmitting the at least one of the plurality of blocks of the video frame.

Systems and methods for sharing content between devices are disclosed. To request a shared piece of media content, a playback device generates and sends a request to content server. The playback device includes information in the request that indicates the playback capabilities of the device. The content server receives the request and determines the playback capabilities of the playback device from the information in the request. The content server then determines the assets that may be used by the playback device to obtain the media content and generates a top level index file for the playback device that includes information about the determined assets. The top level index file is then sent to the playback device that may then use the top level index file to obtain the media content using the indicated assets.

Techniques have been developed to facilitate the livestreaming of group audiovisual performances. Audiovisual performances including vocal music are captured and coordinated with performances of other users in ways that can create compelling user and listener experiences. For example, in some cases or embodiments, duets with a host performer may be supported in a sing-with-the-artist style audiovisual livestream in which aspiring vocalists request or queue particular songs for a live radio show entertainment format. The developed techniques provide a communications latency-tolerant mechanism for synchronizing vocal performances captured at geographically-separated devices (e.g., at globally-distributed, but network-connected mobile phones or tablets or at audiovisual capture devices geographically separated from a live studio).

A method for determining an initial bitrate for a communication includes receiving a communication request to establish a digital communication between a first user device and a second user device associated with a plurality of features including a geographical identifier identifying a geographical location associated with the first user device, a first network type connection associated with the first user device, a second network type connection associated with the second user device, and an average bitrate for a previous digital communication of the first user device. The method includes determining, using an initial bitrate predictor model configured to receive the plurality of features as feature inputs, an initial bitrate for the digital communication between the first user device and the second user device, and establishing the digital communication between the first user device and the second user device at the determined initial bitrate.

A content obtaining method includes: obtaining user behavioral data corresponding to the user terminal and to-be-displayed content on the user terminal; determining an exposure probability of the to-be-displayed content based on the user behavioral data; sending the exposure probability to the content server; and receiving target content fed back by the content server, where the target content is based on the exposure probability, and the target content is triggered by the content server after the content server receives a content obtaining request from the user terminal.

Disclosed is a reaction display method performed by a computer apparatus including processing circuitry, the reaction display method including displaying, by the processing circuitry, a content sharing screen with a voice over Internet protocol (VoIP) call screen during a VoIP call, the content sharing screen including shared media content, and a user of the computer apparatus participating in the VoIP call, receiving, by the processing circuitry, a position at which a reaction is input from the user during the VoIP call, sending reaction information and the position to at least one other user participating in the VoIP call, the reaction information corresponding to the reaction, and displaying an indication of the reaction on the VoIP call screen or the content sharing screen based on the position.

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.

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.

A system and method are provided for dynamic web streaming of media content without restore and batch processing. The system and method provides for a partial restore of media content, where a small sub-section of the archived media is requested by a user, for inclusion in an edit. The exemplary system and method provides a web server that offers grains for any part of an archived monolithic file to be made available just-in-time, instead of the batch processing. Because grains are available over HTTP, any part of the customer's archive is available to them instantly and dynamically with no restore process being required at all.

A method, a system, and a computer program product for determining whether signals are received by one or more devices in a virtual meeting. The method includes transmitting a data stream received from one or more host computing devices to one or more user computing devices in a plurality of user computing devices. The host and user computing devices are communicatively coupled using a real-time online connection. A first hash in a plurality of hashes is generated by the server using a portion of the data stream and stored in a memory location. The first hash is compared to a second hash received from the user computing devices. The second hash is generated by the user computing devices upon receipt of the transmitted data stream. Based on the comparison, a status of the real-time online connection between the host computing devices and the user computing devices is determined.
