摘要： One embodiment of the present invention sets forth a technique for streaming digital media content with transition effects. Audio data may be modulated and received by the streaming device for an audio fade-in effect. Similarly, video data may be modulated to perform various visual effects. Such a technique allows for fading-in of audio and/or video, fading-out of audio and/or video, and effects that blend audio from different content and video from different content during a transition from one digital media content to a different digital media content or within the same digital media content. The modulated audio and video data to generate the audio or video effect during a transition may be precomputed or computed in real-time and transmitted to the streaming device. The streaming device switches between original unmodulated content streams and effect content streams when transitions are detected.
摘要翻译：本发明的一个实施例提出了一种用于流式传输具有过渡效果的数字媒体内容的技术。音频数据可以被流式传输设备调制和接收，以实现音频淡入淡出。类似地，可以调制视频数据以执行各种视觉效果。这种技术允许在从一个数字媒体内容到另一个数字媒体内容的转换期间，音频和/或视频的淡入淡出，音频和/或视频的淡入淡出以及混合来自不同内容的不同内容和视频的音频媒体内容或同一数字媒体内容内。用于在转换期间产生音频或视频效果的调制音频和视频数据可以被预先计算或实时计算并被发送到流传输设备。当检测到转换时，流设备在原始未调制内容流之间切换并影响内容流。

摘要： One embodiment of the present invention sets forth a technique for recommending digital content to a user of a digital content application based on continually learned patterns of behavior. Based on metrics collected from a current session of the digital content application, properties associated with one or more users interacting with the application are inferred. The inferred properties are matched against previously defined patterns of behavior to identify digital content that could be presented to the one or more users for optional selection.

摘要： One embodiment of the present invention sets forth a technique for controlling the operations of a consumer electronic (CE) device. A system includes a display device, CE device, and a remote controller with a touchpad. The CE device is configured to output a context-specific user interface for display by the display device. The particular user interface varies based on the operational context of the CE device. The remote controller sends signals that are detected by the CE device and control operations performed by the CE device. More specifically, the remote controller is used as a handheld pointing device to select operations through interactions with the context-specific user interface. A user may apply gestures to the touchpad that are interpreted based on the context-specific user interface to control the CE device.

摘要： Embodiments of the present invention set forth techniques for a content player to stream a media file using multiple network connections. To stream the media file, the content player downloads metadata associated with a requested media file, establishes a network connection with multiple content servers (or multiple network connections with a single content server or both) and begins requesting portions of the media file. In response, the requested portions are transmitted to the content player. The content player may employ a predictive multi-connection scheduling approach to determine which network connection to use in downloading a given chunk.
摘要翻译：本发明的实施例阐述了内容播放器使用多个网络连接流媒体文件的技术。为了流媒体文件，内容播放器下载与请求的媒体文件相关联的元数据，建立与多个内容服务器的网络连接（或与单个内容服务器或两者的多个网络连接），并开始请求媒体文件的部分。作为响应，所请求的部分被发送到内容播放器。内容播放器可以采用预测多连接调度方法来确定在下载给定块时使用哪个网络连接。

摘要： One embodiment of the present invention sets forth a technique for selecting a content distribution network (CDN) comprising at least one content server, from a plurality of CDNs, and a playing digital content file from the CDN on a content player. Selecting the CDN is based on a rank order of CDNs, an assigned weight value for each CDN, and a bandwidth measured between the content player and each CDN. Advantageously, a given content player may select a CDN based on prevailing network and CDN loading conditions, thereby increasing overall robustness and reliability when downloading digital content file from a CDN.
摘要翻译：本发明的一个实施例提出了一种用于从多个CDN中选择包括至少一个内容服务器的内容分发网络（CDN）和来自内容播放器上的CDN的播放数字内容文件的技术。选择CDN是基于CDN的排序顺序，每个CDN的分配权重值以及在内容播放器和每个CDN之间测得的带宽。有利地，给定的内容播放器可以基于当前的网络和CDN加载条件来选择CDN，从而在从CDN下载数字内容文件时增加总体鲁棒性和可靠性。

摘要： Trick play modes for streaming media programs are facilitated using techniques in a data processor that enable simulated fast forward and rewind motion through a streaming media file without requiring the processor to download, buffer, and display all parts of the media file that exist between a user's current viewing position and another position that is earlier or later in the program. Instead, separate still images generated for the program are successively displayed. Further, the still images may be prepared and stored in advance of the time of playing the streaming media file, and delivered to the playback device at the time that a program is selected for viewing. Similar techniques are described for other aspects of a user interface in a video display, such as for selecting programs from among a library of audiovisual programs and selecting episodes of a series audiovisual program.
摘要翻译：使用数据处理器中的技术来促进流媒体节目的特技播放模式，该技术通过流媒体文件实现模拟的快进和倒带运动，而不需要处理器下载，缓冲并显示存在于用户之间的媒体文件的所有部分当前观看位置以及程序中更早或更晚的另一个位置。相反，为程序生成的独立静止图像会连续显示。此外，可以在播放流媒体文件的时间之前准备并存储静止图像，并且在节目被选择观看时被传送到回放设备。针对视频显示中的用户界面的其他方面描述了类似的技术，例如用于从视听节目库中选择节目并选择系列视听节目的剧集。

摘要： One embodiment of the present invention sets forth a technique for starting playback of an audio portion of digital media content before a video portion of the digital media content is received. An advantage of the disclosed technique is that the perceived delay from the time when a user selects the digital media content to when playback of the digital media content begins is reduced. The audio may be faded-in and one or more still frames of video data may be displayed while the video stream is retrieved. Additionally, a license for DRM (Digital Rights Management) encryption of the title content may be retrieved before starting playback of the video stream, so that the digital media content that is retrieved is also protected.
摘要翻译：本发明的一个实施例提出了在数字媒体内容的视频部分被接收之前，开始重放数字媒体内容的音频部分的技术。所公开技术的优点在于，从用户选择数字媒体内容的时间到数字媒体内容的播放开始时的感知延迟被减少。音频可以是淡入的，并且在检索视频流时可以显示视频数据的一个或多个静止帧。此外，可以在开始重放视频流之前检索标题内容的DRM（数字版权管理）加密的许可证，从而也检索被检索的数字媒体内容。

摘要： One embodiment of the present invention sets forth a technique for deferring license retrieval when streaming digital media content. The perceived delay between the time a user selects the protected digital media content to when playback of the protected digital media content begins is reduced because retrieval and playback of an unprotected version of a portion of the digital media content starts before the license and protected version of the digital media content is received. The unprotected version includes fast start streams of audio and video data that may encoded at a lower bit rate than the protected version in order to quickly transfer the fast start streams from the content server to the playback device.
摘要翻译：本发明的一个实施例提出了在流式传输数字媒体内容时延迟许可证检索的技术。当用户选择受保护的数字媒体内容的时间到受保护的数字媒体内容的播放开始时，感觉到的延迟被减少，因为数字媒体内容的一部分的未受保护版本的检索和回放在许可证和受保护版本接收数字媒体内容。未受保护的版本包括音频和视频数据的快速起始流，其可以以比受保护版本更低的比特率进行编码，以便将快速启动流从内容服务器快速传送到播放设备。
