Abstract

Bandwidth management in each network device in a switched digital video environment. Each device in a user's home and the switched digital video (SDV) device can evaluate the bandwidth requirements of a request from any device in the home and compare it to the bandwidth available at the user's home. This is done as the request is passed upstream from device to device. If there is insufficient bandwidth available, an error message is returned to the requesting device.
