Abstract

Apparatus and methods for providing content to packet-enabled devices in a content distribution network. In one embodiment, a network architecture is disclosed which enables delivery of content to IP-enabled devices such as mobile smartphones and tablet computers using a traditional high-speed data connection. This capability allows the managed network operator to provide content services to an IP-enabled device associated with a non-data subscriber. In one variant, a cable modem is provided which is limited to only retrieve content for delivery to the devices, yet which performs no other functions/services (including provision of high-speed data services). Alternatively, a “media server” modem is utilized to enable delivery of content from the managed network to a client or user device which is also able to obtain high-speed data service from a non-managed or third party managed network via a third-party access point. Security and authentication mechanisms for the transmitted content are also disclosed.

Claims

1. A computerized client apparatus for receiving digitally rendered content from a managed network, the computerized client apparatus comprising:

a communications interface;

a display device; and

a processor apparatus in communication with the display device and the communications interface, the processor apparatus configured to run at least one computer application thereon, the at least one computer application configured to, when executed;

display a listing of a plurality of digital content elements available for access via at least the managed network;

receive data representative of a selection of at least one of the digital content elements from a user of the computerized client apparatus;

based on the selection being effected via a first computer program application associated with the managed network, invoke a pointer process to generate an appropriate pointer within a prescribed address range or space;

based on the selection being effected via a second computer program application not associated with the managed network, invoke a filter process to block any pointers outside the prescribed address range or space;

transmit data representative of a request to a computerized entity for the selected at least one digital content element via the communications interface;

receive a plurality of segments relating to the selected at least one digital content element from the computerized entity via the communications interface;

receive a playlist from the computerized entity via the communications interface; and

use the playlist to utilize at least a portion of the plurality of segments to render the at least one digital content element on the display device.

2. The computerized client apparatus of claim 1, wherein the computerized entity comprises a computerized premises apparatus, the computerized premises apparatus configured to act as a proxy for a managed network apparatus responsible for providing at least some of the plurality of digital content elements to a premises to which the computerized client apparatus belongs.

3. The computerized client apparatus of claim 2, wherein the computerized premises apparatus is configured to transmit at least a portion of the request to the computerized entity in the form of a universal resource locator (URL) within the prescribed range or space.

4. The computerized client apparatus of claim 2, wherein the request is configured by the at least one computer application without a destination address within the managed network, and the computerized premises apparatus is configured to provide a permissible destination address for the request within the managed network from which at least one of the plurality of segments and/or playlist can be obtained.

5. The computerized client apparatus of claim 1, wherein the at least one computer application comprises a login function, the login function configured to, when utilized:

receive login data from the user; and

forward at least a portion of the login data to the computerized entity.

6. The computerized client apparatus of claim 5, wherein:

the at least portion of the login data comprises at least a user ID (identifier) and password, and the at least portion of the login data is forwarded to the computerized entity as part of the request; and

the at least portion of the login data enables establishment of an entitlement of the computerized client apparatus to access the selected at least one digital content element via access to a subscriber database.

7. The computerized client apparatus of claim 1, wherein:

the plurality of segments received from the computerized entity comprise a plurality of transport stream (.ts) files; and

the playlist comprises an M3U (Moving Picture Experts Group Audio Layer 3 Uniform Resource Locator) file.

8. The computerized client apparatus of claim 1, wherein:

the plurality of segments received from the computerized entity are encrypted; and

the at least one computer application is further configured to, when executed, obtain a decryption key from the managed network via the computerized entity.

9. The computerized client apparatus of claim 1, wherein the computerized client apparatus comprises an (Internet Protocol) IP-enabled device, and the plurality of segments are transmitted via an IP multicast within the managed network.

10. The computerized client apparatus of claim 1, wherein the filter process is configured to, when executed, filter data received from the computerized client device against at least one of:

(i) listing of authorized destination addresses, or (ii) a specified range of authorized destination addresses.

11. A computerized method for receiving digitally rendered content from a managed network, the computerized method comprising:

displaying a listing of a plurality of digital content elements available for access from the network on a computerized display device;

receiving a selection of at least one of the plurality of digital content elements from a user;

causing transmission of data representative of a request to a computerized entity for the at least one selected digital content element via a communications interface;

receiving packetized digitally rendered content from the computerized entity via at least one channel configured for delivery of high-speed data services;

limiting a type of service received by the computerized display device to only data services associated with the packetized digitally rendered content, the limiting comprising restricting the computerized display device from receiving the high-speed data services via the at least one channel; and

using the packetized digitally rendered content to render the at least one digital content element on the computerized display device.

12. The computerized method of claim 11, further comprising requesting information from the user, wherein:

the displaying the listing of the plurality of digital content elements available for access occurs only upon receiving the information;

the request comprises the information; and

the receiving the packetized digitally rendered content occurs only upon verification of the information by the computerized entity.

13. The computerized method of claim 12, wherein the information comprises a media access control (MAC) address of the computerized display device at which the at least one digital content element is to be rendered.

14. The computerized method of claim 12, wherein the information comprises login and password information.

15. The computerized method of claim 12, wherein the information comprises information regarding a subscription type or level of the user.

16. The computerized method of claim 11, wherein the limiting the type of service received is performed via at least providing at least one destination address within the managed network from a prescribed list of authorized Internet Protocol (IP) addresses.

17. A non-transitory computer-readable apparatus comprising media configured to store a computer program thereon, the computer program comprising a plurality of instructions which are configured to, when executed by a processing apparatus:

display a listing of a plurality of digital content elements available for access from a managed network on a computerized client device;

receive data representative of a request for at least one of the digital content elements from the computerized client device;

transmit the data representative of the request for the at least one digital content element to a computerized entity;
