Abstract: A method includes receiving information from a tracker device indicating that a plurality of devices is associated with a media content item. The method also includes establishing peer-to-peer sessions with a first group and a second group of the devices, selecting the first group based on a first bit-rate satisfying a threshold bit-rate, and sending a first request, via a first peer-to-peer session, to a first device of the first group. The media content item is divided into a plurality of chunks. The first request identifies a first chunk. The method also includes receiving the first chunk, modifying the threshold bit-rate based on a number of buffered chunks, and selecting the second group based on a second bit-rate satisfying the modified threshold bit-rate. The method also includes sending a second request to a second device of the second group. The second request identifies a second chunk.

Abstract translation: 一种方法包括从跟踪设备接收指示多个设备与媒体内容项目相关联的信息。 该方法还包括与第一组和第二组设备建立点对点会话，基于满足阈值比特率的第一比特率选择第一组，并经由第一组发送第一请求 对等会话到第一组的第一个设备。 媒体内容项被分成多个块。 第一个请求标识第一个块。 该方法还包括接收第一组块，基于缓冲组块的数量修改阈值比特率，以及基于满足修改的阈值比特率的第二比特率来选择第二组。 该方法还包括向第二组的第二设备发送第二请求。 第二个请求标识第二个块。
