    • A method, an equipment and a system for reducing a media delay are disclosed. A media processing unit receives a media switching request sent from a media receiving unit, and sends a response message and a media stream of a second media service to the media receiving unit according to the media switching request, where the response message includes information for the media receiving unit to reduce the media delay, so that the media receiving unit performs a media quickening process on the media stream of the second media service according to the received message including the information for reducing the media delay. An equipment and a system for reducing a media delay are also provided, which increase the switching efficiency of the media streams, reduce the difference of the display delay among different user media, and improve the degree of user experience.

    • Described is a technology by which high dimensional source data corresponding to rows of records with identifiers, and columns comprising dimensions of data values, are processed into a file model for efficient access. An inverted index corresponding to any dimension is built by mapping data from raw dimension values to mapped values based on mapping entries in a dimension table. The record identifiers are arranged into subgroups based on their mapped value; a count and/or an offset may be maintained for locating each of the subgroups. The raw values for a dimension are maintained within a raw value file. For sparse data, the raw value file may be compressed, e.g., by excluding nulls and associating a record identifier with each non-null. A data manager provides access to data in the data files, such as by offering various functions, using caching for efficiency.
    • 描述了一种技术,通过该技术将对应于具有标识符的记录行的高维源数据和包括数据值的维的列处理成用于有效访问的文件模型。 通过根据维度表中的映射条目将数据从原始维度值映射到映射值,构建对应于任何维度的反向索引。 记录标识符根据其映射值排列成子组; 可以维持计数和/或偏移以定位每个子组​​。 维度的原始值保持在原始值文件中。 对于稀疏数据,可以例如通过排除空值并将记录标识符与每个非空值相关联来压缩原始值文件。 数据管理器提供对数据文件中的数据的访问,例如通过提供各种功能,使用缓存来提高效率。

    • Described is a technology by which software program feature usage is located within a sequence of commands collected during program usage sessions. For example, feature generally corresponds to a series of commands, such as copy and paste. A visual modeling component is controlled via drag-and-drop operations to describe a feature model, which is then compiled by a compiler into a finite state machine. Noise models may be used to exclude any command in the sequence that is irrelevant to the feature usage. A recognition process uses the finite state machine to locate program feature usage within the sequence of recorded commands by matching command sub-sequences corresponding to the feature model via the state machine. An analyzer may then use the located matches to provide an analysis report on feature usage.
    • 描述了软件程序特征使用位于在程序使用会话期间收集的一系列命令中的技术。 例如,特征通常对应于一系列命令,例如复制和粘贴。 视觉建模组件通过拖放操作进行控制,以描述特征模型,然后将其由编译器编译成有限状态机。 噪声模型可用于排除序列中与特征使用无关的任何命令。 识别过程使用有限状态机通过状态机匹配与特征模型对应的命令子序列来定位记录命令序列内的节目特征使用。 然后,分析仪可以使用定位的匹配来提供关于特征使用的分析报告。
