Abstract
A method and apparatus for representing host datastream screen image information using markup languages is provided. A distributed data processing system contains a network, at least one host computer, at least one client computer, and optionally at least one server. The host computer generates a host datastream containing host screen image information and forwards the host datastream to a client. If the client is not directly connected to the host, then the host datastream may be routed to the client. The host datastream is converted to a markup language tagged datastream at some point within the network according to a Document Type Definition (DTD) authored for the purpose of representing information in host datastreams. The client receives the markup language tagged datastream containing the host screen image information derived from the host datastream and parses the markup language tagged datastream to identify the host screen image information. The host screen image information is displayed on a display device connected to the client, enabling the client to act as an emulator for the host.
