Abstract

A method and apparatus for controlling access to a video system based on bandwidth consumption include processing that begins as the server monitors bandwidth utilization of connections within the video system. The processing continues when the server receives a request to access a video program via the connection from a client device of the video system. The processing then continues as the server determines whether the bandwidth utilization exceeds a bandwidth threshold. If the bandwidth utilization exceeds the bandwidth threshold, the server provides an indication of viewing-cost options regarding access to the video program to the client device. The processing then continues as the client selects one of the viewing-cost options and provides the selected option to the server. The processing then continues as the server processes the request to access the video program based on the client response.
