Video transfer control protocol for a wireless video demonstrator

Real-time streaming video is expected to emerge as a key service in different telecommunications systems, including wireless networks. This paper presents the functionality and implementation of the wireless Video Control Protocol (VCP). The protocol has been implemented for developing the functionality for real-time video stream transmission over heterogeneous wireless network technologies. VCP is embedded into a wireless video demonstrator. The demonstrator consists of Windows NT hosts containing a real-time H.263 encoder, video stream parsing functionality, and several network connections, such as wireless LAN, Bluetooth and GSM data. The protocol contains functionality for protecting the video stream transfer and adapting different network technologies together.
