Abstract

A method and system for allowing a plurality of devices at a physical drop to receive access to video and/or data services from a plurality of video/data service providers in a digital broadband network serviced by a telecommunication services provider utilizes a broadcast manager, in communication with the video/data service providers, for transmitting an electronic message in a modified format determined by the telecommunication services provider, wherein the electronic message contains information identifying the physical drop, a type of the device being provisioned a the physical drop, and a maximum number of devices for the device type allowed to receive corresponding service at the physical drop. A broadband digital terminal, in communication with the broadcast manager and the physical port, is programmed to receive the electronic message and store the corresponding information. Upon receiving a sign-on request from a requesting device that is requesting access to one of the video and data services, the broadband digital terminal determines whether the requesting device is authorized to access the requested video or data service based on the stored information.

storing the second information at the location servicing the physical drop.

11. The computer readable storage medium of claim 10 further comprising instructions for causing the computer to determine whether the requesting device is authorized by:

determining an address of the requesting device and the physical port originating the sign-on request;

determining if the address of the requesting device matches any one of the stored addresses of the specific devices;

if so, enabling access by the requesting device to the requested video or data service; and

if not, determining whether the number of stored addresses of the specific devices exceeds the maximum number of devices for the device type allowed to receive video or data services at the physical drop.

12. The computer readable storage medium of claim 11 further comprising instructions for causing the computer to determine whether the number of stored addresses exceeds the maximum number of devices for the device type allowed to receive video and data services by:

denying access to the requested video or data service if the number of stored addresses exceeds the maximum number of devices for the device type allowed to receive video and data services at the physical drop; and

adding the address of the requesting device to the stored addresses if the number of stored addresses does not exceed the maximum number of devices for the device type allowed to receive video and data services at the physical drop.
