System and method for packetizing data stream in peer-to-peer (P2P) based streaming service

摘要

A system to packetize a data stream includes a piece generating unit including a processor configured to generate data pieces of the data stream, each data piece being generated during an equal time interval, and a communication unit to transmit the pieces of the data stream. A method that uses a processor to packetize a data stream includes generating, using the processor, data pieces of the data stream, each data piece being generated during an equal time interval, and transmitting the pieces of the data stream. A non-transitory computer-readable medium includes a program for instructing a computer, when executed by a processor, to perform the steps of: generating data pieces of the data stream, each data piece being generated during an equal time interval; and transmitting the pieces of the data stream.

1. A system to packetize a data stream generated by an encoder, the system comprising:
a processor configured to,
generate data pieces of the data stream by determining sizes for each of the data pieces based on a variable bit rate of the encoder such that the data pieces have different sizes set such that each of the data pieces are generated at a first constant rate during an equal time interval regardless of a rate at which the data stream is received, andgenerate, as at least one of the data pieces of the data stream, an empty piece corresponding to a time interval during which the data stream is not received; and a transmitter configured to transmit the pieces of the data stream at a second constant rate such that a sharing ratio is one of maintained and increased, the sharing ratio being based on a server usage of a channel and a number of pieces transmitted over the channel, the server usage being based on an influx rate of peer clients and a number of concurrently connected ones of the peer clients.
