Abstract: A system and method for transcoding and mixing of video data in a security video distribution system for a video security system in response to selection of video data. User devices such as mobile user devices can select displayed video data streams sent from the video security system and create new views of the selected video data streams without the prior steps of configuring and pushing new views from a server within the system.

Abstract: Techniques are described for controlling the process of capturing three-dimensional (3D) video content. For example a controller can provide centralized control over the various components that participate in the capture, and processing, of the 3D video content. For example, the controller can establish connections with a number of components (e.g., running on other computing devices). The controller can receive state update messages from the components (e.g., comprising state change information, network address information, etc.). The controller can also broadcast messages to the components. For example, the controller can broadcast system state messages to the components where the system state messages comprise current state information of the components. The controller can also broadcast other types of messages, such as start messages that instruct the components to enter a start state.
