摘要： 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.

摘要： A method and system that provides a single multipurpose PPV channel that a subscriber tunes for all PPV services. From the subscriber's perspective, the program guide, previews, advertising, purchasing options, and showings of all PPV events occur on a single channel. There can be a single multipurpose PPV channel for all PPV services or single PPV channels for groups of similar services, such as a single Family PPV channel, a single Sports PPV channel, and a single Adult PPV channel that each represent single multipurpose channels for similar programming. The advertising on a single multipurpose channel can be directed to the type of programming on all the channels in the group. Once a subscriber purchases a PPV event, the HCT tunes to the MPEG transport stream and program information for the selected PPV event and displays the PPV event on the single multipurpose PPV channel at its associated start time. The subscriber does not have to select another channel. The subscriber that has not purchased a current PPV event continues to watch the previews, advertising, or program guide uninterrupted on the single multipurpose PPV channel. If a subscriber is watching the single multipurpose PPV channel and has not purchased a PPV event, the subscriber continues to see advertising with video or previews even between the event specific advertising. An interstitial service provides the previews, advertising or PPV guide during the period between PPV event advertisements.

摘要： 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.

摘要： 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.
摘要翻译：在通过通信网络（例如有线电视网络）传送娱乐节目时，用于实现娱乐节目中的交互特征的交互式应用数据被插入到携带娱乐节目的节目流中。由于整个信道带宽临时专用于与编程内容的视频和音频数据相比量相对较小的交互式应用数据的传输，所以当发送时的交互应用数据表现为短的“突发”，导致编程内容传递中几乎不明显的中断。

摘要： A broadcast file system organizes data sent to a client by broadcast via a high capacity data broadcast delivery network from a plurality of servers. The data is organized into a hierarchical file system including a directory index. A server registers to send data via the broadcast file system of the present invention and is assigned a respective directory. The server may create, modify, or delete a subdirectory or a file under the respective directory of that server. The directory index is periodically broadcast. The client caches this directory index and presents the directory index to a client application. The client application may request a portion of data from the directory index. The data available from the plurality of servers is periodically broadcast to the client, and the client filters out the requested portion of data to be provided to the client application. In this manner, broadcast data available from a plurality of server appears to a client application as a hierarchical file system having a directory index similar to that of a computer operating system. Moreover, the client application may request specified data not within the directory index via a two-way communications network. If this data is found, this specified data may be sent to the client via the two-way communication network or via the broadcast delivery network. In addition, the broadcast file system of the present invention may be used for broadcasting data from a database with the directory index organized according to a database schema.
