A method and computing system for receiving, using one or more computing devices, a discrete video stream from each of a plurality of users of a social network, resulting in a plurality of discrete video streams. A synchronous communication session is provided for the plurality of users based, at least in part, upon the plurality of discrete video streams. The plurality of discrete video streams are broadcast to one or more broadcast recipients.

Synchronous communication

Systems and methods described herein relate to detecting the existence of unauthorized content in multiuser composite media stream. In particular, multiuser composite media streams can be examined and to determine if these composite streams include unauthorized content such as copyrighted content or nudity, violence, language violations where desired. The multiuser composite media stream can be partitioned into sections associated with broadcasting users and the portions can be analyzed independently. A notification can be provided to, e.g., the broadcasting user responsible for the unauthorized content in response to detection of the unauthorized content.

Detection of unauthorized content in live multiuser composite streams

One-way streaming video broadcasts can be presented and consumed by an audience via a media player than allows annotations. If the streaming broadcast is live, or at least has not ended, an opportunity exists for the audience to collaborate with the broadcaster and/or contribute to the broadcast. Such can be accomplished by annotating the presentation of the video broadcast with an object that, when selected, facilitates transmission of a video feed associated with the audience member to the broadcaster. The broadcaster can receive and include this video feed into the video broadcast.

Collaboration between a broadcaster and an audience for a broadcast

A multimedia conference broadcast system may include one or more processors and a memory. The one or more processors may receive video streams and audio streams from participant devices. The one or more processors may transmit, to each of the participant devices, the video streams and the audio streams corresponding to the other devices. The one or more processors may receive a request to broadcast the video streams and the audio streams from one of the participant devices. The one or more processors may generate a composite multimedia stream based on the video streams and the audio streams received from the participant devices. The one or more processors may broadcast the composite multimedia stream to viewer devices that are separate from the participant devices.

Multimedia conference broadcast system

Implementations generally relate to facilitating communication between users. In some implementations, a method includes enabling a first user to initiate a chat session with one or more second users, wherein the chat session is a text chat session. The method further includes enabling the first user to broadcast a live video stream to the one or more second users during the chat session. The method further includes enabling at least the first user to convert the chat session to a video session.

Facilitating communication between users

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for chat-enabling a social circle in response to user input provided by a first user, the social circle being defined by the first user and including one or more contacts, the one or more contacts including a second user, for each of the one or more contacts, issuing a chat service subscription request, determining that a subscription request associated with the second user is fulfilled, and in response to determining that the subscription request associated with the second user is fulfilled, adding the second user as a chat contact of the first user and adding the first user as a chat contact of the second user.

Chat-enabled social circles

Implementations generally relate to facilitating presentations in video conferences. In some implementations, a method includes enabling a presenting user to provide a document to a network system. The method further includes enabling the document to be rendered on one or more devices of one or more respective viewing users, where the one or more devices are local to the one or more viewing users. The method further includes enabling the presenting user to navigate the document during a presentation.

Facilitating presentations during video conferences

A computer-implemented technique can include receiving, at a server computing device having one or more processors, a first video stream from a first user computing device associated with a first user. The first video stream can include a first image portion. The technique can further include extracting the first image portion of the first video stream in order to generate a first overlay stream, and receiving a second video stream from a second user computing device associated with a second user. A composite video stream can be generated from the first overlay stream and the second video stream. The composite video stream can comprise the first overlay stream superimposed over the second video stream. The composite video stream can be output to the second user computing device.

Techniques for creating a composite image

A method and computing system for receiving a plurality of discrete audio signals from a plurality of participants of a synchronous communication session. The plurality of discrete audio signals are combined to form a composite audio signal. At least a portion of the composite audio signal is divided into a plurality of sequential time slices. The plurality of sequential time slices are processed to identify one or more copyright-infringing time slices. The one or more copyright-infringing time slices are associated with a copyright infringing participant chosen from the plurality of participants of the synchronous communication session.

Copyright protection

A server-implemented technique can include obtaining external context parameters indicative of an external context of a video chat session, calculating an abuse score based on the external context parameters, the abuse score being indicative of a likelihood the video chat session is abusive, and comparing the abuse score to an abuse score threshold. When the abuse score exceeds an abuse score threshold, the server can transmit, to a reviewer computing device, a request for a human reviewer to review a recorded portion of the video chat session for abuse. When the reviewer computing device returns a response indicating that the human reviewer deemed the video chat session to be abusive, the server can modify a profile of a participant in the abusive video chat session to obtain a modified profile, and generate an output based on the modified profile.

Video chat abuse detection based on external context

Implementations generally relate to providing secure video conferencing. In some implementations, a method includes performing a first encryption of a video stream, wherein the video stream has a first encryption layer from the first encryption. The method further includes performing a second encryption of the video stream, wherein the video stream has a second encryption layer from the second encryption. The method further includes enabling one or more remote nodes to decrypt the second encryption layer. The method further includes enabling one or more end-user nodes to decrypt the first encryption layer.

Providing secure video conferencing

A method and computing system for monitoring an AV synchronous communication session of a user. The AV synchronous communication session includes an audio channel and a video channel. A performance characteristic is determined for the audio channel. The performance characteristic is compared to a defined audio performance threshold. If the performance characteristic does not meet the defined audio performance threshold, the video channel is adjusted to reduce the bandwidth requirements of the video channel.
