摘要： An active stream format is defined and adopted for a logical structure that encapsulates multiple data streams. The data streams may be of different media. The data of the data streams is partitioned into packets that are suitable for transmission over a transport medium. The packets may include error correcting information. The packets may also include clock licenses for dictating the advancement of a clock when the data streams are rendered. The format of ASF facilitates flexibility and choice of packet size and in specifying maximum bit rate at which data may be rendered. Error concealment strategies may be employed in the packetization of data to distribute portions of samples to multiple packets. Property information may be replicated and stored in separate packets to enhance its error tolerance. The format facilitates dynamic definition of media types and the packetization of data in such dynamically defined data types within the format.

摘要翻译：为封装多个数据流的逻辑结构定义并采用活动流格式。数据流可以是不同的媒体。数据流的数据被分割成适合于在传输介质上传输的分组。分组可以包括纠错信息。分组还可以包括用于指示在呈现数据流时提前时钟的时钟许可。 ASF的格式有助于数据包大小的灵活性和选择，并指定可以呈现数据的最大比特率。错误隐藏策略可以用于数据分组化以将样本的部分分发到多个分组。可以将属性信息复制并存储在单独的数据包中，以增强其容错能力。该格式有助于媒体类型的动态定义以及在格式内的动态定义的数据类型中数据的分组化。

摘要： The invention includes a streaming multimedia rendering system having a network client and a network server that form part of a hyperlink web such as the Internet. In accordance with the invention, a hyperlink to multimedia content is actually an indirect link to a referencc file. The reference file contains a plurality of different resource specifiers and a preferred order for attempting communications using the resource specifiers. Each resource specifier designates a transport protocol. A streaming data client open the resource file in response to activation of a hyperlink to the resource file. In response to the resource specifiers contained in the resource file, the network data client repeatedly attempts to establish a streaming data connection using the different resource specifiers, in the preferred order specified in the reference file, or in the preferred order specified by a file referenced by the reference file, until a streaming data connection is successfully established. Each attempt with a different resource specifier uses the transport protocol designated by that different resource specifier. Different types of protocol specifiers are available. Some of the protocol specifiers override configuration settings made at the network data client relating to which transport protocols are permitted.

摘要： In accordance with one or more aspects of the rights enforcement of unencrypted content, a nameplate associated with unencrypted content is generated. The nameplate includes an identifier of the unencrypted content and an identifier of an authorized user of the unencrypted content. The nameplate is sent to a device of the authorized user for rights enforcement of the unencrypted content on the device. In accordance with one or more other aspects of the rights enforcement of unencrypted content, a nameplate for unencrypted content to be played back on a device is obtained. The nameplate includes an identifier of the unencrypted content and an identifier of an authorized user of the unencrypted content. The device presents, during playback of the unencrypted content on the device, the identifier of the authorized user of the unencrypted content.
