US 2011/0258322 A1 · ADAPTIVE DATA RATE STREAMING IN A PEER-TO-PEER NETWORK DELIVERING VIDEO CONTENT

Abstract

A method for increasing bit-rate consumed by a consumer node in a real-time peer-to-peer (P2P) network delivering real-time multimedia content. The method comprises determining desirability to switch to a higher bit-rate consumption respective of a current bit-rate consumption; sending requests to resource nodes of the P2P network for supply of additional bandwidth to support a difference between the higher bit-rate consumption and the current bit-rate consumption; connecting to at least one resource node of the P2P network that can supply the additional bandwidth, thereby increasing bit-rate consumption; determining whether there are connection problems due to the increase in bit-rate consumption; and consuming from the at least one resource node the current bit-rate in addition to the additional bandwidth when no connection problems occur and it is established that the consumer node is capable of handling the higher bit-rate consumption of the real-time multimedia content.

Dependent claims

A method for increasing bit-rate consumed by a consumer node in a real-time peer-to-peer (P2P) network delivering real-time multimedia content, comprising:

determining desirability to switch to a higher bit-rate consumption respective of a current bit-rate consumption;
sending requests to resource nodes of the P2P network for supply of additional bandwidth to support a difference between the higher bit-rate consumption and the current bit-rate consumption;
connecting to at least one resource node of the P2P network that can supply the additional bandwidth, thereby increasing bit-rate consumption;
determining whether there are connection problems due to the increase in bit-rate consumption;
and
consuming from the at least one resource node the current bit-rate in addition to the additional bandwidth when no connection problems occur and it is established that the consumer node is capable of handling the higher bit-rate consumption of the real-time multimedia content.

3 more elements

A real-time peer-to-peer (P2P) network for delivery of real-time multimedia content, comprising:

at least one resource node for delivering real-time multimedia content;
and
a plurality of consumer nodes for receiving the real-time multimedia content distributed by the at least one resource node over a network, the plurality of consumer nodes grouped in at least a first group consuming the real-time multimedia content at a first bit-rate and a second group consuming the real-time multimedia content at a second bit-rate, the second bit-rate is higher than the first bit-rate;
wherein at least one consumer node of the plurality of consumer nodes is adapted to initiate a check and perform a transition from the first group to the second group without being required to handle a bit-rate that is above that of the second bit-rate and while maintaining a stream of the real-time multimedia content at the first bit-rate until it is determined that the at least one consumer node is capable of sustaining the second bit-rate.
