Publication number: 20130152122Abstract: An interactive information distribution system for providing secure distribution of video-on-demand content. The interactive information distribution system includes at least one programming source for storing at least one partially encrypted video program, and a distribution center including a remote server. The remote server stores the at least one partially encrypted video program received from the at least one programming source. The remote server also processes the partially encrypted video program corresponding to a subscriber requested video program to produce a fully encrypted video program. A subscriber-side distribution network, coupled to the distribution center, causes transmission of the fully encrypted video program to the requesting subscriber.Type: ApplicationFiled: February 4, 2013Publication date: June 13, 2013Applicant: Comcast IP Holdings I, LLCInventors: Yong Ho Son, Christopher Goode

Patent number: 8225361Abstract: Techniques to remotely monitor and control operations performed by one or more head-ends (or servers) in an information distribution system. In one implementation, a monitor and control unit communicates with various elements (e.g., an IPG service manager and a session manager) within each head-end to receive information relating to the operations of the head-end. This information may include status and/or indications of possible error conditions relating to (1) various operations (e.g., encoding, multiplexing, and so on) performed by the head-end, and (2) the transport streams being transmitted from the head-end. The received information may then be forwarded to one or more remote devices (e.g., pagers, cellular phones, PDAs) designated to receive the information. Response messages may also be received from the remote devices and forwarded to the appropriate head-end, which may adjust its operation as indicated by commands included in the messages.Type: GrantFiled: December 11, 2000Date of Patent: July 17, 2012Assignee: Cox Communications, Inc.Inventors: Brian Feinberg, Eugene Gershtein, Donald F.

Patent number: 7836474Abstract: A method and apparatus for preprocessing and postprocessing content in an interactive information distribution system. Content is retrieved from a storage medium and encapsulated in accordance to an Internet Protocol (IP) format. The encapsulated content is then uploaded for storage in a stream caching server and for future streaming of content to different types of access networks.Type: GrantFiled: May 4, 2006Date of Patent: November 16, 2010Assignee: Cox Communications, Inc.Inventors: Yong Ho Son, Christopher W.

Patent number: 7801172Abstract: A data packet structure capable of efficiently propagating a payload through a multi-user, digital video distribution system. The system is capable of delivering multimedia data (video and audio information) using the Moving Picture Expert Group (MPEG) packets as payload within a unique packet structure. The packet structure enables routing of the packets through a variety of network topologies. Specifically, the packet structure comprises a packet header, a routing information field, a private data field, digital data payload, and an error correction code field. Such a packet structure enables the network to deliver digital video through a point-to-point, star, ring, dual ring, and other network topologies to a user that is identified in the routine information field.Type: GrantFiled: September 21, 2004Date of Patent: September 21, 2010Assignee: Charter Communications Operating, LLCInventors: Christopher W.

Patent number: 7607148Abstract: Techniques to monitor operation of an information distribution system and delivery of programming, guide data, and other information by the system. These techniques may be used for diagnostics, quality control, and other purposes, and for various types of systems. In accordance with one method, a directive is received to monitor a particular channel at a particular terminal. In response to the received directive, a command is sent (e.g., via a remote control unit) to the terminal. Contents are then received from the terminal, captured, and reported. The reported contents may be used to visually verify the contents being delivered to the terminals, check what the viewers may observe, mimic and test interactive experiences of the viewers, observe actual viewing conditions at the terminals, and perform other tests and diagnostics. The received contents may be captured as one or more video frames, as a video sequence, or in some other format.Type: GrantFiled: December 14, 2000Date of Patent: October 20, 2009Assignee: Cox Communications, Inc.Inventors: Brian Feinberg, Eugene Gershtein, Donald F Gordon, Yong Ho Son, Sadik Bayrakeri

Patent number: 7159235Abstract: A method and apparatus for streaming content to an access network in an interactive information distribution system. The method encapsulates the content in accordance to an Internet Protocol (IP). The content is then transcoded into a format supported by the access network, and streamed over a distribution network to a remote server or to a subscriber terminal that is coupled to the access network. The apparatus is embodied as stream caching server for streaming the content encapsulated within the IP packet to access networks via a stream distribution network in response to a request for content. A packet processor is coupled to the stream server for processing the encapsulated content within the IP packets into a format native to the access network.Type: GrantFiled: January 29, 2001Date of Patent: January 2, 2007Assignee: Sedna Patent Services, LLCInventors: Yong Ho Son, Christopher W.
