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. At the time of selection, user devices can specify operations to perform on the selected video data, such as zoom and combine. In a preferred embodiment, transcoding and mixing of video data streams within the security video distribution system utilizes shared memory between processes. This has advantages not only in equipment cost savings and efficiency, but also provides for real-time collaboration and sharing of video content in a video security system using mobile user devices.

Abstract: Selection and display of adaptive rate video streams in a video security system in which user devices such as mobile computing devices mix and display multiple streams concurrently from security cameras on the user devices. A client application running on the user devices determines available buffer resources on the user devices, and enables selection of one or more video streams from a grid displayed on a display of the user devices. In response to the determined resources, the client application obtains higher bit rate video streams for the selected video streams and lower bit rate video streams for the non-selected video streams. The client application then displays the higher bit rate streams in visually distinct focus panes that attract the attention of an operator and displays the lower bit rate streams in less visually distinct periphery panes. In a preferred embodiment, operators can select a stream from the periphery panes to display as higher bit rate stream in a focus pane.
