Publication number: 20120297460Abstract: A user's set top box (STB), or other client, executes a shell and has an application program interface (API) by which certain features of the client can be controlled. The client is in communication with a walled garden proxy server (WGPS). The client sends a request to the WGPS to access a service provided by a site in the garden. The site sends the client a message containing code calling a function in the API. The WGPS traps the message from the site and looks up the site in a table to determine the access control list (ACL) for the site. The WGPS includes the ACL in the header of the hypertext transport protocol (HTTP) message to the client. The shell receives the message and extracts the ACL. If the code lacks permission, the shell stops execution.Type: ApplicationFiled: May 24, 2012Publication date: November 22, 2012Inventors: Ralph W. Brown, Robert Keller, Milo S. Medin, David Temkin

Patent number: 6678733Abstract: A walled garden contains links to one or more servers providing network-based services. A walled garden proxy server (WGPS) controls access to the walled garden. When a user of a client wishes to access a service in the walled garden, the client sends a request to the WGPS including a plot number identifying the service and a ticket granting the client access to the service. The WGPS denies access to clients lacking a ticket or presenting invalid tickets. In response, the client contacts a gateway server (GS) having a database of users and associated access rights. The user presents authentication information to the GS. If the user positively authenticates, the GS generates a ticket containing a Box ID from the client, an expiration date, and set of bits representing the access rights of the user. The GS encrypts the ticket and gives it to the client.Type: GrantFiled: October 26, 1999Date of Patent: January 13, 2004Assignee: At Home CorporationInventors: Ralph W. Brown, Robert Keller, Milo S.

Patent number: 5822530Abstract: For an interactive communication system, a method and apparatus for processing requests for video-on-demand versions of interactive applications. One embodiment initially receives a request to transmit a video on-demand version of a particular interactive application. This embodiment then determines if transmission of this video-on-demand version would constrain resources of the interactive communication system. If the system's resources would not be constrained, the interactive system provides the viewer with the video-on-demand version of the interactive application. On the other hand, if the system's resources would be constrained by the transmission of the VOD version, then the invention (1) denies the request for the video-on-demand version, and (2) directs the requesting viewer to view a near video-on-demand version of the particular application.Type: GrantFiled: December 14, 1995Date of Patent: October 13, 1998Assignee: Time Warner Entertainment Co.

Patent number: 5797010Abstract: The present invention is a novel system and method for supporting the execution of applications of a full service network whereby each application is designed and compiled to execute in a particular execution environment. As the user/subscriber makes a request for a service, the head end accepts the request as one for the downloading of the application associated with the service. The head end downloads the execution environment associated with the particular application. The execution environment is stored in memory at the requesting set-top processor. The application is also downloaded from the head end server to the requesting set-top processor and stored at the set-top processor. The set-top then executes the environment and the application in turn.Type: GrantFiled: December 22, 1995Date of Patent: August 18, 1998Assignee: Time Warner CableInventor: Ralph W. Brown

Patent number: 5771435Abstract: For an interactive communication system, the invention provides a method and apparatus for processing requests for video presentations of particular interactive applications. One embodiment of the invention initially receives, from a viewing node, a request for a video presentation of a particular interactive application. This embodiment then provides a near-video-on-demand (NVOD) presentation of the interactive application to the viewing node. At the time of the offer of the NVOD presentation, or during the NVOD presentation, the viewing node might request a video-on-demand (VOD) version of the interactive application. If such a request is made, and if the system's resources would not be constrained by the transmission of the video-on-demand presentation of the interactive application, then this embodiment transmits the video-on-demand version of the interactive application to the viewing node.Type: GrantFiled: December 14, 1995Date of Patent: June 23, 1998Assignee: Time Warner Entertainment Co.
