A method, apparatus, system and non-transitory computer-readable record medium for a group call using whisper are provided. The group call method includes participating in a group call session with a plurality of participants; designating at least one participant among the plurality of participants as a whisper target based on a touch gesture during the group call session; generating a whisper packet configured to control a server to transfer, only to the whisper target, at least one of video and audio that are input through an input device while the whisper group is designated; and transmitting the whisper packet to the server through the group call session.

The disclosed embodiments disclose techniques for optimizing the display of videos. During operation, a computing device receives a video stream to be displayed. The computing device determines a preferred orientation for the video stream, determines a present orientation for the computing device, and determines a mismatch between the preferred orientation and the present orientation. The computing device adjusts the video stream while displaying the video stream on the display. As the video stream plays, the computing device detects any rotation of the computing device, and if so, re-adjusts how the video stream is displayed.

A method and apparatus for providing a chat service are provided. The method for providing a chat service according to one embodiment includes providing an invitation target list including a plurality of user groups to a user device of a user participating in a chat room, receiving, from the user device, an invitation request for one or more user groups selected as invitation target user group from among the plurality of user groups, and inviting the invitation target user group to the chat room.

Methods, systems, and storage media for terminating empty joinable group calls are disclosed. Exemplary implementations may: determine, at a first point in time, that there are at least two connected participants in a joinable group call; determine, at a second point in time that is later than the first point in time, that there is a single connected participant in the joinable group call; based on determining, at the second point in time, that there is the single connected participant in the joinable group call, automatically terminate the joinable group call; transmit a termination message to each participant of the joinable group call; and cause display of the termination message on a respective device associated with each participant of the joinable group call.

A system for managing a virtual meeting (e.g., video conference) includes memory storing a video conference application and at least one processor to execute the video conference application to generate a virtual meeting view for a first attendee including multiple attendee video streams arranged according to a virtual attendee arrangement specifying positions of the attendee video streams relative to each other in the virtual meeting view, receive second attendee audio data associated with a second attendee video stream, identify a particular video stream position specified by the virtual attendee arrangement, determine differential stereo effect data corresponding with the particular video stream position, and apply the differential stereo effect data to the second attendee audio data to provide differential audio signals on different audio channels output to the first attendee to create a stereo sound effect corresponding with the particular video stream position.

A system that provides for the accessing and playing of media files having differing associated rights such as non-DRM media files, purchased and downloaded media files, subscription download files such as tethered downloads, and subscription streamed DRM files. The system also provides a method and user interface for sharing a media collection among computing devices in communication via a network. The system allows access and playback, from each computing device on a network, of all media files in a media collection, regardless of their associated rights.

Improved virtual collaboration environments allow participants in a primary collaboration session to initiate side conversations with fellow participants based on virtual locations of each participant within a virtual collaboration layout. The virtual collaboration layout defines virtual locations of each participant in the collaboration session. If a virtual distance between two participants a below a threshold, the participants are able to engage in a side conversation. Management information is provided to a collaboration session host. The management information indicates, for example, a volume or frequency of communication occurring on each side conversation, or an elapsed time since the side conversation was initiated. The host is also provided with controls that allow the host to issue a warning to side conversation participants, to mute the side conversation, or to change a participant's position within the virtual collaboration layout, thus changing the participant's eligibility to participate in the side conversation.

A meeting support system includes: an acquisition processor that acquires medium information corresponding to a communication medium installed in the meeting room by communication of the user terminal with the communication medium; and a permission processor that identifies a meeting in which a user is scheduled to participate acquired from the user terminal, on the basis of user information for identifying the user, and the medium information acquired from the user terminal, and that permits login to a meeting support application of the identified meeting.

Embodiments of the present disclosure provide methods, systems, apparatuses, and computer program products for sharing a shared interface and allowing participants to annotate the shared interface within a group-based communication system. A shared interface is shared by an interface sharing device to participating devices, which can then individually annotate the shared interface by creating interface annotations that then are shared on the shared interface by the interface sharing device. Such methods, systems, apparatuses, and computer program products provide for an efficient and effective method of advancing discussions among a group in a group-based communication system.

A method for use in a computing device, comprising: receiving an invite for a communications session; obtaining context information associated with the invite; generating a signature for the invite based on the context information; generating an attendance score for the invite by evaluating a neural network based on the signature for the invite, the attendance score being an estimate of a degree of importance of attending the communications session; generating a response to the invite based on the attendance score, the response indicating whether a user of the computing device accepts or rejects the invite; and transmitting the response to a sender of the invite.
