A network video server apparatus and method for transferring video image data across a computer network serving multiple clients. The network server apparatus comprises two parts, a server and a client. The server is run on a computer system containing a video digitizer hardware. Running the server on this computer system makes it possible to distribute video images across an existing network linking several client computer systems. The client provides the user with a means of viewing the images generated by the server through the network, controlling the size and type of image to be sent by the server, controlling the underlying video digitizer hardware, and collecting statistics about the server/client performance. The client software is designed to appear to the users as if they were operating the client software locally. The server and client communicate with each other over two channels: one for control information and another for video data. Data transfer from a server to a client is asynchronous such that the server need not wait for a client to complete its receipt before servicing the next client.
