First Claim
Patent Images
1. A method for enabling fast access to a media channel available on a core network from an access node, the method comprising:
- at a multicast enabled access node, receiving a request for the media channel from a subscriber coupled to the access node over an xDSL connection;
if the subscriber is authorized to access the media channel, granting access to the media channel based on subscriber authorization information local to the access node without requesting the subscriber authorization information from the core network in response to the request for the media channel; and
distributing the media channel to the subscriber over the xDSL connection using a multicast protocol available at the access node.

Abstract
A method and system for fast channel changes of media that is provided by carriers over an xDSL connection to a home. Each customer'"'"'s subscriber information is stored at the DSLAM that supports the xDSL connection to the home. Also, each DSLAM supports multicast protocols so that only one instance of a channel is provided on the core network regardless of how many customers have requested access to the channel.

10. An access node for enabling fast access to a media channel available on a core network, the access node comprising:
-
a first network interface that employs a packet-based protocol to exchange packets with the core network; a second network interface for multiplexing a plurality of xDSL connections, each xDSL connection coupling a respective subscriber to the access node; and a transcoder that performs actions, including; receiving a request for the media channel from a particular subscriber, if the particular subscriber is determined to be authorized to access the media channel, granting access to the media channel based on subscriber authorization information local to the access node without requesting the subscriber authorization information from the core network in response to the request for the media channel, and distributing the media channel to the particular subscriber over a corresponding xDSL connection using a multicast protocol available at the access node. - View Dependent Claims (11, 12, 13, 14)

15. A system for enabling fast access to a media channel available on an IP based core network, the system comprising:
-
(a) a multicast enabled access node configured to; enable a subscriber to access the media channel on the core network, wherein the subscriber is coupled to the access node over a local loop data connection, and distribute the media channel to the subscriber over the local loop data connection using a multicast protocol available at the access node; (b) a set top box for sending a request for the media channel from the subscriber to the multicast enabled access node over the local loop data connection; (c) a database for storing subscriber authorization information at the access node, the information being employed to determine whether the subscriber is authorized to access the media channel without requesting the information from the core network in response to the request for the media channel; and (d) a router that enables the core network to establish a single instance of the media channel that is selectable by subscribers authorized at the access node. - View Dependent Claims (16, 17, 18, 19)

20. A method for providing fast access to a media channel available on a core network from a multicast enabled access node, the method comprising:
-
receiving, at the multicast enabled access node, a request for a media channel from a subscriber connected to the access node over a local loop data connection; determining whether the subscriber is authorized to access the media channel based on subscriber authorization information provided at the access node for the subscriber without requesting the subscriber authorization information from the core network in response to the request for the media channel; and enabling the subscriber to access the media channel over the local loop data connection using a multicast protocol if the subscriber is determined to be authorized to access the media channel. - View Dependent Claims (21, 22)
