Abstract

A method and system are provided for delivering video from a client to a server over a communication medium with a limited bandwidth. An initial image quality that allows the video to be displayed in real time at the client is determined based on a predetermined frame rate and the limited bandwidth. Video having the initial image quality is transmitted to the client. While transmitting the video to the client, the server receives a message from the client that indicates selection of a second frame rate that is slower than the predetermined frame rate. In response to the message from the client, the server determines a second image quality that allows the video to be displayed in real time at the client based on the second frame rate and the limited bandwidth. The second image quality is higher than the initial image quality. The video with the second image quality is then transmitted to the client. A 'snapshot' feature is also provided. A predetermined user input is received at the client. In response to the predetermined user input at the client, a message is transmitted from the client to the server that indicates a particular frame in the video. In response to receiving the message at the server, the server transmits to the client data depicting an image represented in the frame, wherein the data represents the image in greater detail than the image is represented in the frame of the video.
