Abstract
Abstract A method and system for providing images from a server to a client over a communication medium with a limited bandwidth is described. In providing the images, a first location in a first video stream that is associated with a first image is identified. Data depicting the first image is then transmitted from the server to the client. In response to receiving a next image request from the client, the server determines a second location in the first video stream that has a particular positional relationship in the first video stream relative to the first location. The server then transmits to the client as the next image a second image associated with the second location. The limited bandwidth of the communication medium is such that playing the first video stream in real time over the communication medium would produce images having a first image quality. However, the first and second images are transmitted at an image quality that is greater than the first image quality.
