摘要： In one embodiment, a method includes retrieving a playlist for a video stream of video content for a client. The playlist is for portions of video content for the video stream. A traffic shaping service determines a set of rules for the playlist for a set of portions in the plurality of portions where each rule is associated with a network condition. For each rule, the method performs: dynamically allocating a port and setting a network condition to apply to the port according to the rule. During playback of the video content, the traffic shaping service receives a request for a portion from the client and determines a port associated with the request for the portion. The method then sends a traffic shaped portion through the determined port where the network condition is applied to the traffic shaped portion based on the network condition being set on the port.

摘要： In one embodiment, a method receives a request for a video stream of video content from a client. A playlist for the video stream is retrieved. The playlist is for a plurality of portions of video content. A traffic shaping service adjusts the playlist for a set of portions in the plurality of portions according to a set of rules where adjusting allows the service to perform traffic shaping for the set of portions. The method then sends the adjusted playlist to the client. During playback of the video content at the client, the traffic shaping service receives a request for a portion in the set of portions from the client using the adjusted playlist. The method determines a rule to apply to the portion where the rule is associated with a network condition and simulates the network condition for the portion to perform the traffic shaping service.

摘要： A method, apparatus, article of manufacture, and a memory structure for playing a media program and providing a preview frame of the media program in response to a seek command is disclosed. In one embodiment, the method comprises the steps of accepting a seek command in the user computer; generating a seek request from the seek command, the seek request including information identifying an arbitrarily chosen seek preview media program frame associated with the media program; retrieving the arbitrarily chosen seek preview media program frame; and rendering the received arbitrarily chosen seek preview media program frame in the playback component of the MPP.
