Selection and Display of Adaptive Rate Streams in Video Security System

摘要

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.

主权项

1. A video security system for selecting and displaying content on user devices, comprising:
one or more security cameras that provide the content in video streams over a security network; client applications executing on the user devices that display the video streams, and select a bit rate for each of the video streams; and a streaming server that accepts the video streams from the security cameras, and provides the client applications with the video streams having different bit rates determined by the client applications.
