摘要： Some embodiments are directed to a method and apparatus for performing resource negotiation in a station implementing a direct communication link with at least one other station on an Orthogonal Frequency-Division Multiple Access (OFDMA) data channel. The station scans sub-channels on the data channel for base headers included in predefined position in transmissions sent on the sub-channel. The station then decodes a base header in at least one selected sub-channel to obtain parameters of a channel reservation. The obtained parameters are stored in a channel utilization table. The station selects a resource on the data channel in at least one of time or frequency that the station has observed to be free using information from the channel utilization table. The station then begins a resource negotiation process about the selected resource.

摘要： Disclosed are methods that associate “importance” information with chunks of a media presentation. An end-user device uses this information to intelligently manage resources when downloading or rendering the media presentation. An editor tags a chunk as important based on the contents of the chunk. The importance information includes a recommendation that this chunk be rendered at a higher-than-usual resolution and that the end-user device start downloading this chunk out of order. An advertiser recommends that an advertisement be rendered at a resolution high enough for the end user to view it appropriately. The importance information can include a recommended point at which to display the advertisement (e.g., between scenes in the media presentation). The end-user device can download advertisements before they are needed. Later, when the user requests a media presentation, an already downloaded advertisement is rendered while the initial chunks of the media presentation are downloaded.
摘要翻译： 公开的是将“重要性”信息与媒体呈现的块相关联的方法。 终端用户设备在下载或呈现媒体演示时使用这些信息来智能地管理资源。 编辑器根据块的内容标记一个重要的块。 重要性信息包括一个建议，该块以高于通常的分辨率呈现，并且最终用户设备开始下载这个块。 广告商建议以足够高的分辨率呈现广告，以便最终用户适当地查看广告。 重要性信息可以包括用于显示广告的推荐点（例如，媒体呈现中的场景之间）。 最终用户设备可以在需要之前下载广告。 稍后，当用户请求媒体呈现时，在下载媒体呈现的初始块时呈现已经下载的广告。

摘要： Disclosed are methods for associating size information with each chunk of a media presentation. This size information is sent to an end-user device. There are many ways to characterize the size of a chunk beyond simply giving the number of bytes in the chunk. Some embodiments send an approximation of the size or a relative size. In some embodiments, a server publishes a “reference” value for a media presentation and then, for each chunk, gives the size relative to that reference value. The device decides whether or not to download the chunk. The device might decide that it is unlikely that the next chunk can be downloaded in time. Then, to avoid the possibility of a video freeze, the device could request the next chunk at a lower resolution. In some situations, the device decides to request a completely different chunk or to not request any chunk at all.
摘要翻译： 公开了将大小信息与媒体呈现的每个块相关联的方法。 该大小信息被发送到最终用户设备。 除了简单地给出块中的字节数之外，还有许多方法来表征块的大小。 一些实施例发送尺寸或相对尺寸的近似值。 在一些实施例中，服务器发布媒体呈现的“参考”值，然后针对每个组给出相对于该参考值的大小。 该设备决定是否下载该块。 该设备可能会决定下一个小块不太可能及时下载。 然后，为了避免视频冻结的可能性，设备可以以较低的分辨率请求下一个块。 在某些情况下，设备决定请求完全不同的块，或者根本不请求任何块。

摘要： A method and apparatus for distributing live video to multiple client devices is provided herein. In particular, a router is provided that acts on behalf of all client devices in its network. The router serves multiple groups of client devices with each group being formed by client devices having similar bandwidth requirements. The router then requests and receives video chunks from a network. The router then redistributes the video chunks to the multiple client devices using a multicast transmission. In particular, to minimize the demands on the core network, the router sets up a separate multicast to each group. Live video, of the appropriate quality is then multicast to each group.

摘要： A method and apparatus for transmitting video is provided herein. A video representation is segmented into video chunks, with each chunk spanning a different time interval. Each chunk may be divided into two or more sub-chunks. During operation, the client requests a sub-chunk of a particular video chunk and then possibly requests an additional sub-chunk of the video chunk. The client then combines and decodes the sub-chunks to provide a reconstructed video chunk for playback on a device. In an embodiment, I-frames of a video chunk are made available in a separate sub-chunk file than P-frames (or B-frames).

摘要： A method is provided which enables the connection of nodes out of communication range while minimizing the energy consumption in standby nodes. Specifically, the present invention provides a method to control the wake up rate of standby nodes in a multi-hop communication system. An access point collects, processes, and refines statistical information regarding one or more system parameters; determines a wake up rate based on the statistical information and one or more historical information; and transmits the wake up rate to nodes in its coverage area. A node receives the wake up rate; and periodically changes from a sleep state to a wake up state at the wake up rate to support routing functions for providing multi-hop communication to the one or more access points.

An end-user device or server uses this information to intelligently manage resources when downloading or rendering the media presentation. Many different types of importance information are used. An editor can tag a chunk as important based on the content of the chunk or may give the chunk a rating, or importance can be inferred from download statistics. In some embodiments, the end-user device determines the importance of a chunk based on observations of the behavior of the device's user. The end-user device can send its locally gathered behavioral observations to a server to enhance that server's demographic information. The server can observe its own download behavior to infer importance. The end-user device may choose to either not download, or to download at a low resolution, those chunks deemed to be unimportant, thus saving bandwidth and battery power.
