Abstract (in Japanese) (See Japanese page) 
(in English) We previously proposed multi-hop communication methods for audio streaming delivery on Bluetooth.
The methods realize a multi-hop relay in a hop-by-hop manner and
the interconnectivity with general Bluetooth audio products that are commercially available.
However, they cannot avoid the occurrence of flame loss due to the synchronization problem on relaying: The upstream nodes start sending
the next packets before the downstream nodes become ready to receive.
Although an end-to-end acknowledge mechanism would be effective for solving this problem, the implementation on existing products is difficult.
In this paper, on the premise of interconnection to existing Bluetooth audio devices,
we proposes a novel multi-hop relaying method that adaptively selects the audio bit rate based on the number of hops. The effectiveness of the proposed method is clarified by the implementation experiments.
