Publication number: 20230412884Abstract: Tools are provided for distributing access-restricted content in an internet protocol television (“IPTV”) environment based on portable entitlement keys. Such tools can include a decoder, an encoder, and a network entitlement handler. The decoder may be configured to receive a key associated with entitlement information, and transmit the entitlement information over a network. The encoder may be configured to receive content from content providers, and to encode the content to create IP-compatible content, with access restrictions based on entitlement. The network entitlement handler may be configured to receive a request for requested content from the decoder; receive the access-restricted content (including the requested content) from the encoder; and transmit the requested content over the network to the decoder using IP, when the decoder is entitled to receive the requested content.Type: ApplicationFiled: June 20, 2023Publication date: December 21, 2023Inventors: Steven M.

Patent number: 8856118Abstract: A method of playing a rich content stream that includes a media stream and a descriptive stream. The method may include the steps of receiving the rich content stream at a media player, where the descriptive stream is generated from a rich content file executed separately from a source for the media stream, and where the media stream and the descriptive stream are received as separate streams at the media player. The method may also include synchronizing the media stream and the descriptive stream at the media player so that information in the descriptive stream is temporally synchronized with media content playing from the media stream. In addition the method may include activating the playing of the descriptive stream while the media stream is playing on the media player, where descriptive content from the descriptive stream is not played on the media player until being activated by a user.Type: GrantFiled: October 31, 2005Date of Patent: October 7, 2014Assignee: Qwest Communications International Inc.Inventors: Steven M.

Patent number: 8752090Abstract: Tools are provided for supporting content syndication to a set top box. The set top box requests a syndicated feed at regularly scheduled times, and receives the syndicated feed through an Internet Protocol (“IP”) network. Hence, a syndicated feed is distributed to the set top box that subscribes to the syndicated feed. Additionally, the set top box converts the syndicated feed for use by the set top box, and causes at least one image based at least in part on the syndicated feed to be displayed on a display device for a user.Type: GrantFiled: June 27, 2008Date of Patent: June 10, 2014Assignee: Qwest Communications International Inc.Inventors: Steven M.

Publication number: 20090007171Abstract: Tools are provided for supporting dynamic insertion of advertisements into a content stream delivered to a viewer through an Internet Protocol (“IP”) network. A viewer profile that includes at least one item of interest and an advertisement profile that includes a mapping from one or more items to at least one advertisement are maintained. An item in the viewer profile is matched to one or more advertisements based on the advertisement profile. The content stream is retrieved and an advertisement slot into which an advertisement should be inserted is identified. The advertisement to be inserted is selected from the one or more advertisements and the content of the advertisement is inserted into the advertisement slot in the content stream. A video component of the content stream with the content of the advertisement inserted is displayed on a display device.Type: ApplicationFiled: June 27, 2008Publication date: January 1, 2009Applicant: Qwest Communications International Inc.Inventors: Steven M.
