摘要

本文介绍了一种无线视频传输演示器的结构。该演示器已用于开发实时视频流服务的控制协议和QoS支持。演示器包含用于视频捕获、编码、流保护和无线链路或网络传输的模块，以及用于解码和在接收器上显示的模块。H.263编码使用专用硬件实时执行。设计并实现了一种视频控制协议，用于管理流传输和采集测量信息。目前的实现是通过无线局域网、GSM数据、蓝牙和一种称为TUTWLAN的专有无线局域网进行操作的。此外，还实现了一个特殊的模块来模拟本地不同的无线链路或网络。

Architecture of a wireless video transfer demonstrator

This paper presents the architecture of a wireless video transfer demonstrator. The demonstrator has been implemented for developing control protocols and QoS support for real-time video streaming services. The demonstrator contains modules for video capture, encoding, stream protection and transfer for wireless link or network, as well as for decoding and displaying at the receiver. H.263 encoding is performed in real-time using dedicated hardware. A video control protocol has been designed and implemented for managing the stream transfer and for collecting measurement information. The current implementation operates over wireless LAN, GSM data, Bluetooth and a proprietary wireless LAN called TUTWLAN. In addition, a special module has been implemented for simulating different wireless links or networks locally.
