Assets, such as content and related data are packaged, transmitted, received and managed in a digital cable television system to standardize the distribution of content and services from a content/service provider to subscribers in the system. The standardized format for packaging content enables the digital cable system to package, transmit, receive and manage diverse types of content, such as MPEGs, executable files, HTML pages, and the like, using standard system components without requiring reprogramming of the system to deploy new services. Service and content providers are freed from having to develop custom formats for delivering content and data to the cable system. Moreover, the standardized bundling of content and related data that is enabled by the invention allows the cable system operator to automate the deployment of services based on specific content and data to select subscribers.

Systems and methods for packaging, distributing and managing assets in digital cable systems

A method for determining whether the terminal is authorized to receive the selected service is practiced in a terminal of a conditional access system in which a user selects a service, the selected service being associated with a frequency, the terminal having a tuner and a secure element with at least one authorized entitlement unit number stored therein. The method includes receiving at least one encrypted entitlement control message corresponding to the service, and decrypting each of the at least one encrypted entitlement control message in the secure element, each decrypted entitlement control message revealing at least one first entitlement number associated with the selected service. The method further includes determining that the terminal is authorized to receive the selected service when any first entitlement number of any decrypted entitlement control message represents any number of the at least one authorized entitlement unit number. Alternatively, the method includes receiving at least one entitlement control message corresponding to the service, and authenticating each of the at least one entitlement control message in the secure element, each authenticated entitlement control message revealing at least one first entitlement number associated with the selected service. The method further including determining that the terminal is authorized to receive the selected service when any first entitlement number of any authenticated entitlement control message represents any number of the at least one authorized entitlement unit number.

In delivering an entertainment program over a communications network, e.g., a cable TV network, interactive application data for realizing interactive features in the entertainment program are interjected into the program stream carrying the entertainment program on an as needed basis. Because the entire channel bandwidth is temporarily dedicated for transmission of the interactive application data, whose amount is relatively small compared with that of the video and audio data of the programming content, the interactive application data when transmitted appears as a short 'burst,' causing a virtually unnoticeable interruption in the programming content delivery.

Systems and methods that divide the billing function of a billing system from the provisioning function of a service in digital cable systems. Because the billing system is only responsible for billing, rather than the provisioning of services, new services may be quickly added to cable systems without the time consuming and expensive task of configuring the billing system specifically for new services added to the system. The services are implemented using an offering package created by the service, where the offering package contains billing related information forwarded to the billing system to bill for the service.

Systems and methods facilitate the provisioning of a new service in a cable system without requiring that server hardware and/or software be changed to implement the service, or that an equivalent session manager be created in a set-top box. Session requests are generated at the STB and transmitted to the service, which then interprets the request, rather than forwarded from the STB to a server implementing the service, as in conventional systems. To effect the routing to the service the session request contains routing information. Servers facilitating the implementation of services do not know details about, or even the existence of, new services added to the system.

A system and method are provided for providing a full service cable television system. The cable system incorporates a digital and analog transmission architecture capable of delivering a high number of high quality television programs, advanced cable services, and online services to a subscriber's home. The cable system comprises a cable headend, at least one fiber transport, at least one distribution hub, at least one hybrid fiber coax plant, and a plurality of set-top terminals. Programs and services are transmitted to the set-top terminals in both digital and analog formats to maintain downward compatibility with existing systems. The set-top terminal incorporates a central processing unit, a unified memory architecture, a memory management unit, communications circuitry, I/O control circuitry, and audio and video output circuitry. Through these components the set-top terminal provides advanced cable services such as a comprehensive channel navigator, an interactive program guide, Impulse Pay-Per-View activation, Near-Video-On-Demand and Video-On-Demand programming, and advanced configuration controls. The set-top terminal also provides online services such as World Wide Web browsing, Internet E-Mail, and Home Shopping.
