摘要： A system and method are provided for filtering messages propagated among peer servers in a distributed virtual world. Each peer server hosts a virtual space within the virtual world and filters messages based on the state and properties of its virtual space. In order to propagate messages, messages originating in a virtual space are first provided to the peer server hosting that virtual space. The peer server propagates the messages to one or more of its neighboring peer servers hosting virtual spaces that neighbor its virtual space in the virtual world. These peer servers may then propagate the messages to their neighboring peer servers. When propagating the messages, the peer servers either apply filter rules to the messages or append filter rules to the messages in order to filter the messages based on the state and properties of the virtual spaces hosted by the peer servers.

摘要： A multicast query propagation scheme for a Peer-to-Peer (P2P) network is provided. A number of first level (L1) peer nodes are associated with a second level (L2) peer node to form an L1 peer group. The L2 peer node operates as a super peer node for the L1 peer group and allocates two Source-Specific Multicast (SSM) channels operating as a control and query channel for the L1 peer group. Similarly, a number of other L1 peer groups are formed. An L2 peer group is formed by a third level (L3) peer node and the L2 peer nodes. The L3 peer node operates as a super peer node for the L3 peer group and allocates two SSM channels operating as a control and query channel for the L2 peer group. Using the control and query channels of the L1 and L2 peer groups, queries are propagated throughout the P2P network.

摘要： A system and method for smart trick mode display which is aware of content and metadata, user context and user interests, and selects frames to display during trick mode that may be of interest to the user, and filters frames that the user might not wish to see even inadvertently. More specifically, the media system and method for smart trick mode display analyzes a recorded video content during a trick mode playback of the recorded video; and identifies segments of the content that are least one of interest to the user or should not be displayed to the user. The system may then select keyframes or a short sub-segment of the segment of interest to the user and then either displays the keyframes or sub-segments in a manner so as to catch the user's attention, or specifically not display any keyframes or sub-segments having content that the user does not wish to see.

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.

摘要： Systems and methods are disclosed for obtaining and presenting information to a user playing a media item identifying playback positions of a number of other users also playing the media item. In one embodiment, a first user begins playback of a media item. Information identifying playback positions of a number of second users also playing the media item is obtained from a playback information broker and presented to the first user. The first user may then provide user input identifying a desired action to take with respect to one or more of the second users. In response, the desired action is effected.

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： A system and method are provided for enabling information sharing in a distributed virtual world. In general, a virtual world client associated with a user participating in a virtual world operates to obtain one or more annotations associated with virtual world constructs identified as being of interest to the user. The virtual world constructs of interest to the user may be identified by the user or identified automatically by the virtual world client. In one embodiment, the one or more annotations are defined by other users participating in the virtual world. Once the one or more annotations are obtained, the virtual world client may, for example, present the one or more annotations to the user, present a portion of the one or more annotations to the user, notify the user that the one or more annotations are available, or the like.

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： Systems and methods are disclosed for generating and utilizing photo advertisements (“ads”). In one embodiment, a photo advertisement is posted as a status update for a user via a social networking service. More specifically, first, one or more photo ad templates are obtained for the user, where each photo ad template includes one or more photo wells. A photo advertisement is then generated based on one of the photo ad templates such that a filler image of a different one of one or more participants identified for the photo advertisement is inserted into each of the one or more photo wells in the photo ad template. The photo advertisement is then used as a status update for the user. In another embodiment, the photo advertisement is stored and subsequently used to serve ad requests.
