Abstract
One or more network based video servers is/are connected to one or more video receivers over a shared network. Pieces of video content are each encoded at a number of constant quality levels and stored on one or more of the network based servers. Responsive to requests from a receiver, video content is selected on a server and delivered over the shared network to the receiver. The system selects the quality level of the stream to deliver based on characteristics of the video stream currently being delivered, and the number of bits already buffered at the video receiver and the available network throughput. The aim is to select the video quality being delivered according to the available network throughput to maximize quality while ensuring that video data is delivered over the network in time to be decoded and displayed without interruption. Certain exemplary embodiments make that selection in advance.
