DISTRIBUTION METHOD, PLAYBACK APPARATUS, AND DISTRIBUTION APPARATUS
First Claim
1. A distribution method in a distribution system, in which streaming data of a variable bit rate is packetized and distributed from a distribution apparatus to one playback apparatus among a plurality of playback apparatuses, and the distributed streaming data is transferred from the one playback apparatus to other one or more playback apparatuses among the plurality of playback apparatuses, the distribution method comprising:
- measuring, by a playback apparatus, among the plurality of playback apparatuses, which transfers the received streaming data to the other one or more playback apparatuses, a communication quality between the playback apparatus and each of the other one or more playback apparatuses of transfer destinations; and
redividing, by the playback apparatus, the received streaming data into packets based on a playback data amount for each unit playback time in the received streaming data and on the measured communication quality and transferring the resulting streaming data.

Abstract
A distribution apparatus packetizes streaming data of a variable bit rate, and distributes the resulting data to a plurality of playback apparatuses. The distributed streaming data is transferred from one playback apparatus to other one or more playback apparatuses. One playback apparatus measures the communication quality between the one playback apparatus and each of the other playback apparatuses of transfer destinations. One playback apparatus redivides the received streaming data into packets based on a playback data amount for each unit playback time in the received streaming data and on the measured communication quality and transfers the resulting streaming data.

3. A playback apparatus which receives streaming data of a variable bit rate in a packetized state, plays back the received streaming data, and transfers the received streaming data to another playback apparatus, the playback apparatus comprising a processor configured to perform a procedure including:
-
measuring a communication quality between the playback apparatus and the another playback apparatuse; and redividing the received streaming data into packets based on a playback data amount for each unit playback time in the received streaming data and on the measured communication quality and transferring the resulting streaming data. - View Dependent Claims (4, 5, 6)

7. A distribution apparatus which distributes streaming data to a plurality of playback apparatuses, the distribution apparatus comprising a processor configured to perform a procedure including:
-
acquiring a communication quality between the distribution apparatus and each of the plurality of playback apparatuses and a communication quality between every two of the plurality of playback apparatuses; and determining a distribution path of the streaming data so that the streaming data is transferred in a daisy chain fashion among the plurality of playback apparatuses, based on each of the acquired communication qualities. - View Dependent Claims (8, 9)
