    Abstract: A digital rights management (DRM) system for distribution of digital content such as audio or video uses a token passing scheme to enhance security of the content from unauthorized access and use, including access by unauthorized players. The token is requested from the central content or DRM server by a host device such as a user's computer, using security related information. The token is then passed to a media player associated with the host device, the token being encrypted using a key special to that particular player. Upon receipt of the token, the player transmits back to the server certain related security information confirming receipt of the token and in return receives keys for decryption of the associated digital content. In the absence of proper passing of the token, player access to the content, or further access to other content, is denied. This also allows the player to communicate directly with the server for obtaining the keys.

    Abstract translation: 用于分发诸如音频或视频的数字内容的数字版权管理（DRM）系统使用令牌通过方案来增强内容的未经授权的访问和使用的安全性，包括未经授权的玩家的访问。 使用安全性相关信息，通过诸如用户计算机的主机设备从中央内容或DRM服务器请求令牌。 然后令牌被传递到与主机设备相关联的媒体播放器，该令牌使用该特定播放器特有的密钥进行加密。 在接收到令牌时，播放器向服务器发送确认令牌的接收的某些相关的安全信息，并且返回接收关于数字内容的解密的密钥。 在没有正确传递令牌的情况下，播放器对内容的访问或对其他内容的进一步访问被拒绝。 这也允许播放器直接与服务器通信以获得密钥。

    Abstract: At least a portion of a media file (400) can be downloaded by accessing one or more items of media data associated with a media file stored on a remote server, wherein the media data (415) includes at least one sample table, receiving input from a user identifying a playback location associated with the media file; determining a plurality of data items (430,435) required to play at least a portion of the media file from the identified playback location based on the at least one sample table; and transmitting one or more byte-range requests to the.remote server using the hypertext transfer protocol to retrieve the plurality of data items (430,435). Further, the media file can be progressively downloaded from the identified playback location until the end of the media file is reached, playback of the media file is terminated, or input is received from the user identifying a new playback location.

    Abstract translation: 可以通过访问与存储在远程服务器上的媒体文件相关联的一个或多个媒体数据项来下载媒体文件（400）的至少一部分，其中媒体数据（415）包括至少一个采样表，接收输入 从用户识别与所述媒体文件相关联的播放位置; 基于所述至少一个样本表，确定从所识别的播放位置播放所述媒体文件的至少一部分所需的多个数据项（430,435）; 以及使用所述超文本传输​​协议向所述远程服务器发送一个或多个字节范围请求以检索所述多个数据项（430,435）。 此外，可以从识别的播放位置逐渐下载媒体文件，直到到达媒体文件的结束，媒体文件的播放被终止，或者从用户接收到识别新的播放位置的输入。

    Abstract: A display mode can be selected by identifying a plurality of display modes supported by a media client, wherein the plurality of display modes comprise safe display modes; generating a user interface including a test image and a plurality of commands in accordance with a selected display mode of the plurality of display modes, wherein the user interface is output to a display device; receiving user input selecting one of the plurality of commands; and configuring an operating display mode of the media client in accordance with the received user input. Configuring an operating display mode further can comprise determining that the received user input confirms the selected display mode and configuring the media client to set the selected display mode as the operating display mode. Further, generating a user interface can comprise presenting a display timer indicating a time remaining until a display mode change.

    Abstract translation: 可以通过识别由媒体客户端支持的多个显示模式来选择显示模式，其中多个显示模式包括安全显示模式; 根据所选择的多种显示模式的显示模式生成包括测试图像和多个命令的用户界面，其中所述用户界面被输出到显示设备; 接收选择所述多个命令之一的用户输入; 以及根据接收的用户输入配置媒体客户端的操作显示模式。 进一步配置操作显示模式可以包括确定所接收的用户输入确认所选择的显示模式并且配置媒体客户端以将所选择的显示模式设置为操作显示模式。 此外，生成用户界面可以包括呈现显示定时器，指示剩余时间直到显示模式改变。
