System and Method of Adaptive Bit-Rate Streaming

摘要

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.

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