摘要： Disclosed are methods that associate “importance” information with chunks of a media presentation. 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.

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： 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： 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： 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： The environment surrounding an end-user device is analyzed. When a user of the device requests a download of a media presentation, the device uses the results of the environmental analysis to automatically request an alternative audio or video track for the media presentation. By choosing a better alternative before the download even begins, the device avoids user frustration and conserves resources. For example, a user requests a music video to be played on his mobile phone. By using its microphone, the phone analyzes its current audio environment and concludes that there is considerable background noise. Then when requesting a download of the music video, the phone requests an “enhanced-clarity” soundtrack to increase the odds that its user will be able to hear the music over the background noise. In some situations, the alternative track is rendered in addition to, rather than instead of, the default tracks of the media presentation.

摘要： A group of “servant” devices each downloads a media presentation and renders the presentation to a local user. However, a “master” device directs the servants as to which chunks to download and when to render the presentation. In this way, the master keeps the presentations on the separate servants in synchrony. The master uses status information from the servants to coordinate the downloads. If, for example, one servant is having a difficult time keeping up with the presentation, then the master may choose to direct that servant to download a reduced-resolution version of the presentation (which requires less bandwidth to download). If the user of one of the servant devices enters a playback command, then that command is not executed locally but is instead sent to the master device which in turn sends the command to all of the servants so that they may execute the playback command in synchrony.
摘要翻译： 一组“仆人”设备每个都下载媒体演示，并将演示呈现给本地用户。 但是，“主”设备可以指导仆人下载哪些块以及何时呈现演示文稿。 通过这种方式，主人会同时将演示文稿保存在单独的服务器上。 主人使用仆人的状态信息来协调下载。 例如，如果一位仆人难以与演示文稿保持一致，那么主人可以选择指导该仆人下载演示文稿的降解版本（需要更少的带宽下载）。 如果其中一个服务器设备的用户进入播放命令，则该命令不在本地执行，而是发送到主设备，主设备又将命令发送到所有服务器，以便它们可以同步地执行播放命令 。
