    • This disclosure includes techniques for signaling characteristics of a representation of multimedia content at a representation layer, such as frame packing arrangement information for the representation. In one example, an apparatus for receiving video data includes a processing unit configured to receive information indicative of whether a bitstream includes a packed frame of video data, wherein the packed frame comprises two frames corresponding to different views of a scene for three-dimensional playback, and wherein the information is present in a representation layer external to a codec layer of the bitstream, automatically determine whether the apparatus is capable of decoding and rendering the bitstream based on an analysis of the received information and decoding and rendering capabilities of the device, and retrieve the bitstream when the processing unit determines that the device is capable of decoding and rendering the bitstream.
    • 该公开内容包括用于在表示层上用于表示多媒体内容的表示的特征的技术,例如用于表示的帧包装布置信息。 在一个示例中,用于接收视频数据的设备包括:处理单元,被配置为接收指示比特流是否包括视频数据的打包帧的信息,其中所述打包帧包括对应于用于三维回放的场景的不同视图的两个帧 ,并且其中所述信息存在于所述比特流的编解码器层外部的表示层中,基于所接收的信息的分析和所述设备的解码和呈现能力自动地确定所述设备是否能够对所述比特流进行解码和呈现, 以及当所述处理单元确定所述设备能够对所述比特流进行解码和呈现时,检索所述比特流。

    • A server may provide information describing characteristics of audio and video components to a client, separately from encoded samples of the audio and video components themselves. The client may use the information to select components, and then to request the selected components, e.g., in accordance with a streaming network protocol. In one example, an apparatus for sending encapsulated video data includes a processor configured to determine characteristics for components of a plurality of representations of video content, wherein the characteristics comprise at least one of a frame rate, a profile indicator, a level indicator, and dependencies between the components, and one or more interfaces configured to send the characteristics to a client device, receive a request from the client device for at least one of the components after sending the characteristics, and send the requested components to the client device in response to the request.
    • 服务器可以向音频和视频组件本身的编码样本分开地向客户端提供描述音频和视频组件的特征的信息。 客户端可以使用该信息来选择组件,然后例如根据流网络协议来请求所选择的组件。 在一个示例中,用于发送封装的视频数据的装置包括被配置为确定视频内容的多个表示的组件的特征的处理器,其中,所述特征包括帧速率,简档指示符,级别指示符和 组件之间的依赖关系以及被配置为向客户端设备发送特性的一个或多个接口在发送特性之后从组件中的至少一个组件接收来自客户端设备的请求,并响应于所请求的组件发送给客户端设备 要求。

    • A method for use with an information (or data) warehouse comprises managing the information warehouse with instructions in a declarative language. The instructions specify information warehouse-level tasks to be done without specifying certain details of how the tasks are to be implemented, for example, using databases and text indexers. The details are hidden from the user and include, for example, in an information warehouse having a FACT table that joins two or more dimension tables, details of database level operations when structured data are being handled, including database command line utilities, database drivers, and structured query language (SQL) statements; and details of text-indexing engines when unstructured data are being handled. The information warehouse is managed in a dynamic way in which different tasks—such as data loading tasks and information warehouse construction tasks—may be interleaved (i.e., there is no particular order in which the different tasks must be completed).
    • 一种与信息(或数据)仓库一起使用的方法包括以声明性语言的指令管理信息仓库。 该指令指定要完成的信息仓库级任务,而不指定如何实现任务的某些细节,例如使用数据库和文本索引器。 详细信息是从用户隐藏的,并且包括例如在具有连接两个或多个维度表的FACT表的信息仓库中,当处理结构化数据时的数据库级别操作的细节,包括数据库命令行实用程序,数据库驱动程序, 和结构化查询语言(SQL)语句; 以及正在处理非结构化数据时文本索引引擎的细节。 信息仓库以动态的方式进行管理,其中不同的任务(例如数据加载任务和信息仓库构建任务)可以被交错(即,不存在必须完成不同任务的特定顺序)。
