摘要
蓝牙技术是一种抗干扰能力强、保密性好、功耗低的短距离无线通信方式。MPEG4是一种压缩率高、对传输带宽要求低、图像质量高的图象编码技术。提出了一套视频传输系统的实现方案。该方案基于OMAP1510具有的独特双核结构,结合蓝牙和MPEG4编码技术,实现窄带宽下的视频图像实时传输。分析了影响系统性能参数的因素,并提出了相应的改进方案。
Bluetooth is a wireless technology characterized with good security,low power and anti-interference. MPEG4 is a video coding technology with the characters of high compression ratio,low requirement for transmission bandwidth and high quality of image. This paper presents a method of video data transmission based on Bluetooth. It is based on the OMAP1510 which has a special dual core structure,and uses MPEG4 technology. At the end of the paper, the author analyses the facts that affect the properties of the system and presents the method to improve them.
