Abstract
Multiple streams of data are streamed to a user's terminal with images from different cameras. Low resolution thumbnail images tell the user what image streams are available. A focus stream provides high resolution images from a selected camera. A user can switch the focus stream to another stream by clicking on the associated thumbnail. The users can also be provided with a thumbnail of panoramic image. Other data streams sent to the user can contain (a) audio data, (b) interactivity markup data which describes regions of the image which provide interactivity opportunities such as hotspots, (c) presentation markup data which defines how data is presented on the user's screen, (d) a telemetry data stream which can be used for various statistical data. One data stream contains a low quality base image for each data stream which can be enhanced to form a high resolution focus image.
