摘要
由于蓝牙无线信道带宽较窄且动态变化 ,在其上实时传输连续媒体数据是一个巨大挑战 .本文研究了其中若干关键技术 ,包括蓝牙通信技术、视频 /音频压缩技术和自适应服务质量控制技术等 .文中提出了一种基于简单网络管理协议 (SNMP)的自适应服务质量控制方案 ,设计了蓝牙多媒体传输管理信息库 (简称 BMT- MIB) ,通过动态监测当前蓝牙无线信道和终端系统状态 ,有效利用带宽等资源 .
Because of the limitation and variation of the bandwidth, real-time media transmission over wireless channels such as Bluetooth is a challenging task. This paper addresses several key technologies on real-time media transmission over bluetooth, including bluetooth communication, video/audio compression as well as QoS monitoring and adaptive control. In order to effectively use resources such as bandwidth, this paper proposes a novel adaptive QoS control scheme for Bluetooth wireless multimedia based on SNMP, which dynamically monitors the current Bluetooth channel and end-system status through the Bluetooth Multimedia Transmission MIB(BMT-MIB) designed by us. Furthermore, this paper discusses the design and implementation of the remote monitoring system over Bluetooth.
