摘要
ZigBee是以IEEE 802.15.4标准为基础的一种低成本、低功耗的无线网络技术,通过ZigBee协议栈,可将各ZigBee节点形成一个节点容量大、通信范围广的ZigBee网络。而H.264是当今最好的视频压缩标准,具有码流率低、图像质量高、容错能力强等优点。使用ZigBee网络来传输H.264视频码流,是实现无线视频传输系统的一种好方案。通过具体开发实例,从硬件和软件两个方面讨论了该方案的设计与实现。
ZigBee is a low-cost and low-power wireless network technology based on IEEE 802.15.4 standard. A large capacity and wide range ZigBee communication network can be formed using various ZigBee nodes through the ZigBee protocol stack. H. 264 is currently the best video compression standard with a low stream rate, high image quality and high fault-tolerant capability etc. It＇ s a good scheme to realize wireless video transmission system using the ZigBee network to transmit H. 264 video stream. The design and realization of hardware and software are discussed through a representative example.
