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.

1. A method for providing non-character data to a client computer system at a client site coupled to an application server located at an application server site in a network using a character-oriented protocol in order to run applications, wherein the network includes a data server connected to the application server, the method comprising the steps of:initiating a non-character data request from the client site to the application server site, said request comprising at least the client's site location identification (ID); andin response to said request, performing steps required to access and provide said requested data in an encapsulated manner, logically separated from a front-end host application program at the client site for receiving the non-character data;wherein the performed steps required for accessing and providing said requested data in an encapsulated manner comprises the steps of:requesting the location of said non-character data from said data server;feeding a dedicated program component associated with said application server with said client's side location ID and the location of said non-character data;preparing a data transfer to said client system comprising said non-character data;initiating an activation of a universal program component associated with the client and dedicated to serve the non-character data to said client site; andproviding said client computer system with the requested data in order to be rendered at said client site by said front-end host application program. 2. The method according to claim 1 in which said data transfer is a data stream. 3. The method according to claim 1 in which said character-oriented protocol is IBM3270 protocol, or SNA protocols LU 0, LU 2, or LU 6.2, or TELNET. 4. A system for providing non-character data to a client computer system at a client site coupled to an application server located at an application server site in a network using a character-oriented protocol in order to run applications, wherein the network includes a data server connected to the application server, the system comprising:means for initiating a non-character data request from the client site to the application server site, said request comprising at least the client's site location identification (ID); andmeans for performing, in response to said request, steps required to access and provide said requested data in an encapsulated manner, logically separated from a front-end host application program at the client site for receiving the non-character data;wherein the means for performing steps required to access and provide said requested data in an encapsulated manner comprises:means for requesting the location of said non-character data from said data server;means for feeding a dedicated program component associated with said application server with said client's side location ID and the location of said non-character data;means for preparing a data transfer to said client system comprising said non-character data;means for initiating an activation of a universal program component associated with the client and dedicated to serve the non-character data to said client site; andmeans for providing said client computer system with the requested data in order to be rendered at said client site by said front-end host application program. 5. The system according to claim 4 in which said data transfer is a data stream. 6. The system according to claim 4 in which said character-oriented protocol is IBM3270 protocol, or SNA protocols LU 0, LU 2, or LU 6.2, or TELNET. 7. A system comprising:a networka client computer system in said network at a client site;an application server in said network at an application server site and coupled to said client computer system, said application server using a character-oriented protocol in order to run applications;said client computer system initiating a request for non-character data to the application server site, said request comprising at least the cli ent's site location identification ID;said application server, in response to said request, accessing and providing said requested non-character data in an encapsulated manner;a front-end host application program at the client site for receiving the non-character data;a data server connected to the application server operable for providing the requested non-character data;said client computer system operable for requesting the location of said non-character data from said data server;a dedicated program component associated with the application server feeding said location ID and the location of said non-character data to said application server and preparing a data transfer to said client system comprising said non-character data;a universal program component associated with the client and dedicated to serve the non-character data to said client computer system; andsaid front-end host application program in said client computer system rendering said non-character data at said client site. 8. The system according to claim 7 in which said front-end application program includes a viewer, or an audio player, or a video player. 9. The system according to claim 7 in which said front end host application program is logically separated from the accessing and providing of said requested non-character data. 10. A computer program product comprising a computer usable medium having computer readable program code means therein for providing non-character data to a client computer system at a client site coupled to an application server located at an application server site in a network using a character-oriented protocol in order to run applications, wherein the network includes a data server connected to the application server, said computer readable program code means in said computer program product comprising:computer readable program code means performing the claimed method steps, is inherent in disclosure;computer readable program code means for initiating a non-character data request from the client site to the application server site, said request comprising at least the client's site location identification (ID); andcomputer readable program code means for performing, in response to said request, steps required to access and provide said requested data in an encapsulated manner, logically separated from a front-end host application program at the client site for receiving the non-character data;wherein the computer readable program code means for performing steps required to access and provide said requested data in an encapsulated manner comprises:computer readable program code means for requesting the location of said non-character data from said data server;computer readable program code means for feeding a dedicated program component associated with said application server with said client's side location ID and the location of said non-character data;computer readable program code means for preparing a data transfer to said client system comprising said non-character data;computer readable program code means for initiating an activation of a universal program component associated with the client and dedicated to serve the non-character data to said client site; andcomputer readable program code means for providing said client computer system with the requested data in order to be rendered at said client site by said front-end host application program. 11.
