An improved method and system is provided for providing the end-user of a mainframe application running a limited, character-oriented transfer protocol like the IBM3270 protocol with a combined rendering of non-character, i.e. new media data and traditional character data preferably on the same end-user computer. It is proposed to install an individually programmed program component (28), called Server Media Resolution Service (SMRS) on the application server (16) site and a matching program component (30), called Client Media Resolution Service (CMRS) which is a universal, standard component without any individual application specific features. The SMRS is told the client computer destination, searches the requested media address and feeds this meta information to the CMRS which in turn manages the start of a client site media renderer in order to render the new media data received from a datastore such as the File System (20). A practical example of the media renderer could be a media player (14) which requests and renders a streamable asset provided by a a stream server (22) to said media player (14). Thus, when any change in the host application program is required such changes have to be done in the host application only, the SMRS and the plurality of CMRS components may, however, remain untouched which reduces system programmers work significantly.
