Abstract: Technologies are described for enabling co-streaming of live video game streams by multiple broadcasters. For example, broadcasters that are eligible to co-stream can be determined. Invitations can be sent to the broadcasters to join a co-stream. After acceptance, a co-stream can be created. The co-stream can be streamed to viewer devices.

Abstract: A broadcast computing device broadcasts an audiovisual stream via a computer network to a plurality of viewing computers. The broadcast computing device stores production information according to a hybrid data type. The broadcasting program receives a request to update the stored production information from a viewing computer, and updates the production information.

Abstract: A method comprises electronically communicating with a game program executing on a broadcaster computer configured to stream a broadcast of the game program, the game program supporting a set of game program methods and not a set of viewer program methods. The method further comprises electronically communicating with a viewer program executing on an audience computer configured to remotely present the broadcast, the viewer program supporting the set of viewer program methods and not the set of game program methods. The method further comprises receiving, from the viewer program, an indication of an invoked viewer program method. The method further comprises translating the indication into a corresponding indication of a game program method, and electronically communicating the indication of the game program method to the game program to effectuate output of the game program corresponding to the indicated game program method.

Abstract: A method for distributing a shareable video experience among plural video-consumer devices includes receiving a data stream defining the shareable video experience and generating first and second shared video experiences. The first experience is configured for video-consumer devices capable of real-time interaction with the shareable video experience; it includes a first video stream conveying visual content of the shareable video experience and a first set of interface controls, the first set of interface controls being useable by video-consumer devices capable of real-time interaction to modify the shareable video experience. The second experience is configured for video-consumer devices incapable of real-time interaction; it includes a second video stream conveying visual content of the shareable video experience and a second set of interface controls that are useable by video-consumer devices incapable of real-time interaction to present supplementary data in connection to the shareable video experience.

Abstract: A method for interactive event broadcasting includes receiving a video stream depicting an interactive event. Data representing one or more interactive event controls is received, the interactive event controls being manipulable by a viewer of the interactive event to provide input to the interactive event. The video stream depicting the interactive event and the one or more interactive event controls are displayed as components of a user interface, the video stream and the interactive event controls having a first spatial relationship. Based on detecting a change in state of the interactive event, the first spatial relationship between the video stream and the one or more interactive event controls is changed to a second spatial relationship.

Abstract: Technologies are described for enabling a network protocol that supports switching between communication modes, including a plain text mode and a compressed mode. Switching between the plain text mode and the compressed mode can be performed without closing a network connection between devices. The network protocol can support communication among the devices interacting with a live interactive video game streaming service. The network protocol can also communicate throttling and/or aggregation messages between the devices of the live interactive video game streaming service.

Abstract: An application development component of a development computing system runs a software application developed with the application development component in a pre-build preview state. A broadcast feature editing component of the development computing system changes a state of a pre-production preview version of a broadcast feature associated with a broadcasting service configured to broadcast graphical content output by a post-build version of the software application. An event synchronization component of the development computing system detects the changed state of the broadcast feature and, based on the changed state, alters the running of the software application in the pre-build preview state.
