Technology for interoperability is disclosed by enabling the sharing of user context or preferences for a computing experience across computing devices, operating systems, applications, or locations. A platform and application programming interface (API) are provided for computer applications and services to store and retrieve context data associated with a computing experience. Access to the context data for sharing may be managed by an access controller, which enables a user to manage access permissions for the sharing of the context data. The context data may be defined according to a common schema, which specifies the information for sharing and may be communicated using common communication channels or protocols. Thus context data may be shared across nearly any application or service including those developed in different computer programming languages or operating on different types of computing devices or devices running different operating systems or by different software developers.

The present invention relates to an application that is configured to be operated in a multi-participant environment on a computer network. The application manages participants in an online session of a multi-user application so that if one of the participants exits the session, the session can continue without interruption. The application initiates an online session of the multi-user application, wherein the online session includes two or more participants comprised of network computers that are communicatively linked to a computer network. If the application detects that a first participant has disconnected from the online session, wherein the first participant is responsible for managing certain managerial functionality associated with the running of the multi-user application, then the application broadcasts a notification to existing participants of the online session over the communication network, thereby notifying the existing participants that the first participant has disconnected from the online session. The initiating application then re-assigns the functionality associated with the first participant to an existing participant of the online session. The participants can be communicating in a peer-to-peer arrangement or can be performing server duties in a client-server arrangement.

A method for a computer system includes receiving a first user communication, determining a first group of users, determining a target number of users, determining whether the first group of users includes the target number of users, and if not, providing the communication to the first group of users, determining a hierarchal mapping of groups of users in response to user memberships, determining a second group of users from the hierarchal mapping, determining a plurality of social network relationship factors for the second group of users with respect to the first user, and providing the communication to at least a subset of users in the second group of users in response to the first plurality of social network relationship factors.

Disclosed in one example is a method of authenticating with multiple social network services. The method may include storing first authentication information associated with a user for a first social networking service using at least one computer processor, receiving second authentication information associated with the user for a second social networking service from a social networking application, and sending to the social networking application the first authentication information. The first authentication information may enable the social networking application to utilize a protected application programming interface call for the first social networking service and the second authentication information may enable the social networking application to utilize a protected application programming interface call for the second social networking service.

A method and apparatus for sharing presentation data, interactions, and annotation information between devices. The method includes: converting the presentation data into at least one image; transmitting the at least one image to the second device; displaying an image from among the at least one image on a screen of the first device, and transmitting image identification information about the displayed image to the second device; adding annotation data to the displayed image, based on a user input; and transmitting annotation information about the annotation data to the second device. The second device displays an image corresponding to the image identification information on a screen of the second device based on the image identification information, and the second device displays the annotation information on the image displayed on the screen of the second device the annotation information.

Systems and methods for providing ephemeral streaming spaces may include (1) providing a user with a digital display of video cards, in which each video card within the digital display corresponds to a contact, of the user, designated as currently available for video conferencing, (2) receiving user input selecting a video card from the digital display, and (3) in response to receiving the user input, initiating a video conference between the user and a contact corresponding to the selected video card. Various other methods, systems, and computer-readable media are also disclosed.

Technology for a first multimedia telephony services over internet protocol (IP) multimedia subsystems (IMS) (MTSI) client operable to support region of interest (ROI) signaling with a second MTSI client is disclosed. The first MTSI client can identify a requested region of interest (ROI). The first MTSI client can encode the requested ROI for transmission to the second MTSI client via a real-time transport control protocol (RTCP) feedback message. The first MTSI client can decode encoded video received from the second MTSI client that corresponds to the requested ROI.

Systems and methods for recording a meeting using a retroactive record feature. The present technology provides for improved systems and methods for providing a recording of a virtual meeting, where a selection to initiate the recording from the beginning or an earlier time in the meeting from a current time may be received after the virtual meeting has started. The system may process received meeting content streams to generate a plurality of data segments that may collectively form a meeting recording. Each data segment, for example, may include meeting content associated with a particular user/attendee and associated with a timestamp and/or time duration. In some examples, the plurality of data segments may be stored on a blockchain, which may provide an immutable meeting record that may be concatenated together and made available for playback based on a selection to record the meeting and consent given by the users/attendees.
