摘要： A TV cable system having one set-top per user. The set-top's VCR recording functions are automatically adjusted in a manner to accommodate the occurrence of a program-delay event or a program-cancel event by the TV cable system. The expected begin/stop time-slot during which a program is projected to occur is broadcast by the system's head end to each set-top, and this IPG data is stored in each set-top. Within each set-top, the currently stored IPG-data is periodically compared to IPG-data that was recorded in the set-top's VCR-record-timers at an earlier time. When the recorded IPG-data does not compare to the current IPG-data, the IPG-data that is recorded in the VCR-record-timer is automatically updated to the current IPG-data. When this automatic updating of one VCR-record-timer produces a time-slot conflict with a different VCR-record-timer, the conflict is resolved, either automatically or by a user-alert-message that enables user intervention to resolve the conflict.

摘要： An interactive cable TV system includes a large number of set-top terminals that are connected to a system headend by way of a low-speed, time division multiplexed, channel. The headend includes the mass storage of multimedia data-assets that each contain a large number of individual data-items that may be of interest to various set-top users. A set-top user initiates an inquiry to the data-asset storage by way of an item-descriptor comprising a word-picture of the item. When this set-top query is received at the headend, a table or list is established whereby the query and its set-top ID are associated with related data assets. As the headend's data-asset storage is changed from time to time, the changes that relate to listed set-top queries result in an update of the query list. This updated data-asset information is sent to the related set-tops immediately, or is sent only when the headend receives a request from the related set-top.
摘要翻译：交互式有线电视系统包括通过低速，时分多路复用通道连接到系统头端的大量机顶终端。头端包括多媒体数据资产的大容量存储，每个数据资产都包含大量各种机顶盒用户可能感兴趣的个别数据项目。机顶盒用户通过包含该项目的单词图像的项目描述符发起对数据资产存储的查询。当在头端接收到该机顶查询时，建立表或列表，由此查询及其机顶ID与相关数据资产相关联。随着头端的数据资产存储不时更改，与列出的机顶盒查询相关的更改导致查询列表的更新。该更新的数据资产信息立即发送到相关的机顶盒，或仅当头端从相关的机顶盒接收到请求时发送。

摘要： An interactive application on a set top computing is downloaded to the set top computing system from a headend in an interactive television network. The interactive application is automatically executed by the set top computing system currently running a video program for display on a television set connected to the set top. The automatic begins by waiting for an application token embedded in the video program and detecting the application token. In response to the detection of the application token, the video program is terminated and the application downloaded to the set top is captured. The application is then executed in the set top computing system for display on the television set. In addition, a warning token also embedded in the video program is detected. Then in response to detection of the warning token, the downloading of the ITV application to the set top computing system is initiated. The executing step is synchronized with completion of the termination of the running of the video program so that execution of the application begins immediately upon completion of the termination of the video program. The application is executed in the set top computing system, and a current context is stored as an origination reference. When the application is exited, the current context is launched to return the set top operations to the origination reference point from which the application was launched.
