Transmitting video data over a communications network

摘要

Analogue video and audio signals are produced (12) by a video camera (11). The signals are converted into digital data by a laptop computer (13) which is used to produce a data stream (14). The data stream is transmitted via an ISDN modem and a portable satellite communication device (15) to a remote streaming server (16). The streaming server can transmit the data stream to a plurality of receivers over the Internet, thereby achieving a live broadcast. The portability of the camera, laptop computer and satellite communications device means that the system can be used in remote locations virtually anywhere in the world by one person.
