    Abstract: Television programming information comprising an electronic programming guide is compressed by more than fifty percent, and decompressed in environments with only moderate processing power and storage space. The coding scheme of the present invention is based on Huffman coding of characters comprising the electronic programming guide and replacement character strings occurring in the data that have high savings values. A look-up table and binary tree are constructed from the Huffman codes for use in compressing and decompressing the electronic programming guide, and a set-top box for use in the decompression operation is provided.

    Abstract: A system is provided in which an interactive television program guide is implemented on user television equipment such as a set-top box. The program guide provides an operator showcase in the form of one or more operator showcase television listings screens, each of which contains a set of television listings information. The sets of television listings information are generated by querying a database of television listings data in a database in the set-top box. Each database query is based on content criteria previously selected by the cable system operator or other service provider. The service provider is also able to define the format with which the television listings information is displayed in the television listings screens. A title and logos may also be selected by the service provider for each screen. The operator showcase television listings screens may therefore by customized and branded by the service provider. The user may access multiple operator showcase television listings screens using a centralized operator showcase menu.

    Abstract translation: 提供了一种系统，其中在诸如机顶盒的用户电视设备上实现交互式电视节目指南。 节目指南以一个或多个运营商展示电视列表屏幕的形式提供运营商展示，每个屏幕包含一组电视列表信息。 通过在机顶盒的数据库中查询电视列表数据的数据库来生成电视列表信息。 每个数据库查询基于先前由有线系统运营商或其他服务提供商选择的内容标准。 服务提供商还能够定义在电视列表屏幕中显示电视列表信息的格式。 服务提供商也可以为每个屏幕选择一个标题和标志。 因此，运营商展示电视列表屏幕可以由服务提供商定制和品牌化。 用户可以使用集中操作员展示菜单访问多个操作员展示电视列表屏幕。

    Abstract: Systems and methods for automatically generating a playlist of series assets and systems and methods for grouping assets of a playlist in clusters are provided. In one embodiment, series assets may automatically be included into a playlist for that series. In another embodiment, an interactive media guidance application may group assets in clusters based on one or more user selected parameters or may group assets in cluster based on automatically determined parameters. In yet another embodiment, the interactive media guidance application may group assets in clusters and display at least one identifier in connection with each cluster to indicate a basis for forming the cluster. The identifier may be a key word or catch phrase that succinctly identifies a trait or characteristic of assets in a particular cluster associated with the identifier.

    Abstract translation: 提供了用于自动生成系列资源和系统的播放列表的系统和方法以及用于对群集中的播放列表的资产进行分组的方法。 在一个实施例中，系列资产可以自动被包括在该系列的播放列表中。 在另一个实施例中，交互式媒体引导应用可以基于一个或多个用户选择的参数对资产进行分组，或者可以基于自动确定的参数来对集群中的资产进行分组。 在另一个实施例中，交互式媒体引导应用可以对集群中的资产进行分组，并显示与每个集群相关联的至少一个标识符，以指示形成集群的基础。 标识符可以是简洁地标识与标识符相关联的特定集群中的资产的特征或特征的关键词或捕捉短语。
