Abstract: A system interconnects multiple client devices over a network. A local group of the client devices is located at a live event and a remote group is located remote from the live event. Each client device of the local group is a potential source of a live stream which, when rendered by another client device, causes display of a vantage point of the live event. The system dynamically updates a subscription list to include an indication of any client device of the local group that is actively live streaming and remove an indication of any client device of the local group that terminated live streaming. The system can enable selective access to any live streams of any client device of the updated subscription list and disable access to any live streams of any client device removed from the updated subscription list.

Abstract: A method for targeted content insertion in real-time streaming. The method leverages the different ordered signals available on a multi-step process that clients follow when subscribing to a real-time media (video and/or audio) stream including selecting a region, connecting to a control channel, and subscribing to a stream to guide a multi-stage process of content selection, transcoding, and insertion in a real-time media stream. A system is also specified for implementing the described method on a real-time streaming architecture.

Abstract: A client device is communicatively coupled to a platform that distributes live streams over a network to multiple client devices. The live streams provide a live broadcast of a live event from multiple viewpoints captured by source devices including a first source device. A first live stream is provided to the client device, which renders a first viewpoint captured from the first source device. The client device is displays a second viewpoint with a different vantage point by rendering a second live stream of a second source device. The second live stream is delayed for rendering until a beginning of a next scene of the first live stream.

Abstract: A real-time streaming service predicts an incoming flash crowd event and manages computing resources to respond to the event before traffic peaks, thus reducing the likelihood that the streaming service's resources will be overwhelmed. Embodiments of a real-time streaming server predict a flash crowd event by detecting actions by client devices during a multi-step process to access a real-time content stream from an endpoint server cluster. Initially, the endpoint server has first computing resources configured to stream the content stream to the client devices. The streaming server provisions second computing resources at the endpoint server based on a rate at which the client devices perform an action associated with a first step in the multi-step process. The second computing resources are configured to stream the real-time content stream based on a rate at which the client devices perform an action associated with a second step in the multi-step process.

Abstract: The following describes techniques to maintain continuity of a live media stream. A media stream includes a first distribution layer with a first set of key frames and a set of delta frames succeeding key frames in the first set of key frames. The media stream also includes a second distribution layer including a second set of key frames, where the second set of key frames contains fewer key frames than the first set of key frames. Using the first and second distribution layers, a client device may subscribe to the media stream with a minimized start-up time and optimized quality of experience among varying complexity of the media content and dynamic network conditions.

Abstract: A method includes communicatively coupling a first client device to a platform that distributes live streams over a network to client devices. The live streams provide a live broadcast of a live event from multiple viewpoints captured by source devices including a second client device. An indication is received of a selection of a first viewpoint from the first client device and, in response, a first live stream is provided to the first client device. The first client device is caused to display a second viewpoint with a different vantage point by rendering a second live stream of a second source device. The second live stream is delayed for rendering until a beginning of a next scene of the first live stream.

Abstract: The disclosed embodiments include at least one method. The method includes communicatively coupling a first client device to a platform that distributes live streams over a network to client devices including the first client device. The live streams provide a live broadcast of a live event from viewpoints captured by source devices located at the live event including a second client device. The method further includes receiving an indication of a selection of a first viewpoint from the first client device and communicating a first live stream to the first client device. The first live stream is captured by a first source device and, when rendering by the first client device, causes display of the first viewpoint on the first client device.

Abstract: The following describes techniques to maintain continuity of a live media stream. A media stream may include a first distribution layer at a first bit-rate with at least one key frame at a first time relative to a time domain and a set of delta frames succeeding the first key frame. The media stream may also include a second distribution layer including at least one key frame at a second time that is shifted in time relative to the first time. A device may subscribe to the media stream with a minimized start-up time and optimized quality of experience among varying complexity of the media content and dynamic network conditions.

Abstract: Presented here are methods and systems for enabling multiple consumers to view an ordered data stream at the same time. An embodiment of the invention follows a client-server model, in which there is one server that is the source of the data and multiple clients that are the consumers of the data. Additionally, this invention can also be embodied by a number of other models, including but not limited to: 1) multiple servers or server clusters acting as data sources, and multiple clients acting as consumers, 2) pure peer-to-peer, where each peer can be both a source and/or a consumer of data, 3) a server-assisted peer-to-peer model, where peers may be both a source and/or a consumer of data and a set of one or more servers act as source and back-up and provide meta-information about the peers, such as which data is available from which peer.
