Embodiment Construction

[0088] From now on, embodiments of the present invention will be described in detail with reference to the accompanying drawings. According to the authentication system related to the present invention, only when the authentication is successful, the partner to be communicated can be regarded as the device receiving the stream for playback. Therefore, relatively low-strength protections can be used to secure data transmissions without assuming that the transmitted data can be recorded.

[0089] Taking audio transmission via Bluetooth as an example, embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0090] Bluetooth uses a global radio frequency called ISM (Industry Science Medical) of 2.4 GHz, and provides a synchronous transmission channel of 64 kbps applicable to voice transmission of a telephone and an asynchronous transmission channel applicable to data The normal data transfer rate of 1Mbps is transmitted...

Abstract

When transmitting data such as audio data which require protection to be provided, difficulty levels of authentication are switched corresponding to processing power of equipments to communicate. Thus, for an equipment of low processing power may perform a Bluetooth communication based on the SDMI. Further, for a communicating counterparty which is an equipment of high processing power, such as a personal computer, sufficient countermeasures against hacking may be taken.

Description

technical field [0001] The present invention relates to a radio communication system wirelessly connecting a plurality of devices, a radio communication control device and a radio communication control method, a storage medium, and a computer program, and more particularly to radio communication for transmitting audio data among a plurality of devices wirelessly connected within a predetermined communication cell System, radio communication control device and radio communication control method, storage medium, and computer program. [0002] More specifically, the present invention relates to a radio communication system, a radio communication control device, and a radio communication control method for transmitting audio data between devices in a piconet including a master device and a plurality of slave devices, such as Bluetooth , a storage medium, and a computer program, particularly relating to a radio communication system for transmitting digital data such as audio data b...
