Abstract
A broadband system includes a broadband switch network, a broadband session controller, and a broadband service control point. The broadband network provides connections between information sender/receivers in response to instructions from a broadband service control point or in response to requests originated by an information sender/receiver. The broadband service control point provides processing instructions and/or data to the broadband controller and information sender/receiver. Applications supported by the broadband network include video-on-demand and videoconferencing services for system users. For video-on-demand, a settop controller is associated with a video display of each system user. One or more video information providers ("VIPs") stores video information to be sent to the user's settop controller via the broadband switch network. The broadband session controller communicates with the user's settop controller and VIPs and requests processing information from the broadband service control point in response to predetermined triggers. The broadband session controller instructs the broadband switch network to establish the broadband connection between the VIP and a prede…
