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.
Claims19
A method for enabling fast access to at least one channel over an xDSL connection, comprising:
- (a) employing at least one multicast enabled Digital Subscriber Line Access and Multiplexer (DSLAM) to enable access to at least one channel on a core network, wherein at least one subscriber is coupled to the core network by the xDSL connection;
- (b) at a multicast enabled DSLAM, receiving a request for at least one channel from a subscriber, wherein the receiving DSLAM locally serves the xDSL connection for the subscriber;
- (c) employing information stored at the receiving DSLAM to determine whether the subscriber is authorized to access the requested channel;
- and
- (d) if the subscriber is determined to be authorized to access the requested channel, employing the DSLAM to provide access to the requested channel on the core network, wherein the core network establishes a single instance of each channel that is selectable by subscribers.
2 more elements
A Digital Subscriber Line Access and Multiplexer (DSLAM) for enabling fast access to at least one channel over an xDSL connection, comprising:
- (a) a network interface that employs a packet-based protocol to send and receive packets with a core network and another network interface for multiplexing local xDSL connections that are associated with a subscriber;
- and
- (b) a transcoder that performs actions, including:
- (i) enabling multicast operation of the DSLAM for accessing at least one channel on the core network, wherein at least one subscriber is coupled to the core network by the xDSL connection;
- (ii) receiving a request for at least one channel from a local xDSL connection associated with a subscriber;
- (iii) employing stored information to determine whether the subscriber is authorized to access the requested channel;
- and
- (iv) if the subscriber is determined to be authorized to access the requested channel, providing access to the requested channel on the core network through the local xDSL connection associated with the subscriber, wherein the core network establishes a single instance of each channel that is selectable by subscribers.
5 more elements
A system for enabling fast access to at least one channel over an xDSL connection coupled to an IP based core network, comprising:
- (a) at least one multicast enabled Digital Subscriber Line Access and Multiplexer (DSLAM) to enable access to at least one channel on the core network, wherein at least one subscriber is coupled to the core network by the xDSL connection;
- (b) a set top box for sending a request for at least one channel from a subscriber to a multicast enabled DSLAM, wherein the receiving DSLAM serves a local xDSL connection for the set top box;
- (c) a database for locally storing information at the receiving DSLAM, the information being employed to determine whether the subscriber is authorized to access the requested channel;
- and
- (d) a router that enables the core network to establishe a single instance of each channel that is selectable by subscribers, wherein if the subscriber is determined to be authorized to access the requested channel, the receiving DSLAM is employed to provide access to the requested channel on the core network.
2 more elements
A computer-readable medium that includes instructions for performing actions, including:
- (a) employing at least one multicast enabled Digital Subscriber Line Access and Multiplexer (DSLAM) to enable access to at least one channel on the core network, wherein at least one subscriber is coupled to the core network by the xDSL connection;
- (b) at a multicast enabled DSLAM, receiving a request for at least one channel from a subscriber, wherein the receiving DSLAM serves a local xDSL connection for the subscriber;
- (c) employing information stored at the receiving DSLAM to determine whether the subscriber is authorized to access the requested channel;
- and
- (d) if the subscriber is determined to be authorized to access the requested channel, employing the DSLAM to provide access to the requested channel on the core network, wherein the core network establishes a single instance of each channel that is selectable by subscribers.
2 more elements
A method for enabling fast access to at least one channel over an xDSL connection, comprising:
- (a) means for employing at least one multicast enabled Digital Subscriber Line Access and Multiplexer (DSLAM) to enable access to at least one channel on a core network, wherein at least one subscriber is coupled to the core network by the xDSL connection;
- (b) at a multicast enabled DSLAM, employing means for receiving a request for at least one channel from a subscriber, wherein the receiving DSLAM serves a local xDSL connection for the subscriber;
- (c) means for employing information stored at the receiving DSLAM to determine whether the subscriber is authorized to access the requested channel;
- and
- (d) if the subscriber is determined to be authorized to access the requested channel, employing the DSLAM to provide access to the requested channel on the core network, wherein the core network establishes a single instance of each channel that is selectable by subscribers.
