摘要： A semantic based trick play method and system in a media player is provided in which a semantic trick play command is received from a user while the user is experiencing a current content of a media item. Metadata is detected with respect to a current playback position of the media item, and at least one further playback position is determined in the current content of the media item or a related content in another media item. The further playback position is semantically related to the metadata of the current playback position. Playback is then moved to the at least one further playback position, so that the user experiences a media content of the at least one further playback position.

摘要： Systems and methods are provided for obtaining look-ahead segments for a streaming media item during playback such that the viewer can easily skip to the look-ahead segments without experiencing any substantial interruption or delay in playback. In general, a streaming media source begins streaming a media item to a streaming media client for playback. In one embodiment, the streaming media client selects one or more segments of the media item as one or more look-ahead segments to prefetch from the streaming media source. Then, while the media item is being streamed to the streaming media client for playback, the streaming media client prefetches the one or more look-ahead segments of the media item from the streaming media source. The look-ahead segments are thereafter utilized to enable the viewer to skip ahead in playback without experiencing a substantial interruption or delay in playback.
摘要翻译：系统和方法被提供用于在播放期间获得用于流媒体项目的预先段，使得观看者可以容易地跳到预览段而不会在播放中经历任何实质的中断或延迟。通常，流媒体源开始将媒体项流送到流媒体客户端进行播放。在一个实施例中，流媒体客户机将媒体项目的一个或多个片段选择为从流媒体源预取的一个或多个预览片段。然后，当媒体项目被流传输到流媒体客户端以进行播放时，流媒体客户端从流媒体源预取媒体项目的一个或多个预先段。此后，先行片段用于使观众能够在播放中跳过，而不会在播放中出现实质的中断或延迟。

摘要： A message propagation scheme for a distributed virtual world is provided. In general, each of a number of peer servers hosts a cell of the virtual world, where the cell is also referred to herein as a virtual space. A peer server issues an advertisement/subscription (ad/sub) message, or message flow path setup message, identifying message types produced by the virtual objects in the virtual space hosted by the peer server and message types consumed by the virtual objects in the virtual space hosted by the peer server. Based on the ad/sub message, for each message type produced, message flow paths from the peer server to other peer servers hosting virtual objects that are consumers of the message type are identified. Likewise, for each message type consumed, message paths from other peer servers hosting virtual objects that are producers of the message type to the peer server are identified.
摘要翻译：提供了分布式虚拟世界的消息传播方案。一般来说，多个对等服务器中的每一个托管虚拟世界的单元，其中单元在这里也称为虚拟空间。对等服务器发布广告/订阅（广告/子）消息或消息流路径建立消息，识别由对等服务器托管的虚拟空间中的虚拟对象产生的消息类型以及虚拟对象在虚拟对象中消耗的消息类型由对等服务器托管的空间。基于广告/子消息，对于生成的每个消息类型，识别从对等服务器到托管作为消息类型的消费者的虚拟对象的其他对等服务器的消息流路径。同样，对于消耗的每个消息类型，标识了将来自作为消息类型的生成者的虚拟对象的其他对等服务器的消息路径发送到对等服务器。

摘要： A method and system for constructing and presenting a consumption profile, a rating profile, or both a consumption profile and a rating profile for a media item are provided. In general, consumption of a media item by a number of first users is tracked. Thereafter, before and/or during playback of the media item by a second user, a consumption profile for the media item is constructed and presented to the second user. In addition to or as an alternative to tracking consumption of the media item by the first users, ratings for the media item may be obtained from all or a subset of the first users. Thereafter, before and/or during playback of the media item by the second user, a rating profile for the media item is constructed and presented to the second user.
