In one aspect, a method for generating a graphical display at a client includes transmitting output from an application program executing on a server to the client, identifying a non-textual element within the application output, retrieving a compressed data format associated with the non-textual element, and transmitting to the client the compressed data format in place of the non-textual element. In another aspect, a method for generating a media presentation at a client includes transmitting output from an application program executing on a server to the client, identifying a media stream within the application output, intercepting an original compressed data set representing at least a portion of the media stream before processing by the application program, and transmitting the original compressed data set to the client. ## Claims ### Claim at position 1 1-133. (canceled) ### Claim 134 A method of generating a media presentation at a client, comprising: receiving, by a server, an indication of a media format supported by a client agent that executes on a client device; determining, based on the received indication of the media format supported by the client agent, that a media format of a media stream rendered by an application program executing on the server is supported by the client device; monitoring, by an output filter module executing on the server, the media stream rendered by the application program, the media stream comprising a compressed data set; intercepting, by the output filter module, the compressed data set of the media stream rendered by the application program; and transmitting, from the server, the compressed data set to the client device for decompression by the client device. ### Claim 135 (depends on 134) The method of claim 134, further comprising: establishing an operating mode of the server based on the received indication of the media format supported by the client agent. ### Claim 136 (depends on 134) The method of claim 134, further comprising: receiving, by the server, a list of media formats supported by the client agent, the list corresponding to one or more external codecs installed on the client. ### Claim 137 (depends on 134) The method of claim 134, further comprising: monitoring, by the output filter module, calls made to an operating system of the server. ### Claim 138 (depends on 134) The method of claim 134, further comprising: detecting, by the output filter module, a display command from the application program executing on the server. ### Claim 139 (depends on 134) The method of claim 134, further comprising: determining, by the output filter module, that the media stream generated by the application program comprises a bitmap representation of a non-textual element. ### Claim 140 (depends on 134) The method of claim 134, further comprising: determining, by the server, that the media stream comprises a decompressed data set; and compressing, by the server, the decompressed data set into a media format supported by the client device. ### Claim 141 (depends on 134) The method of claim 134, further comprising: transmitting, to the client device, information for locating images of the media stream on a display screen. ### Claim 142 (depends on 134) The method of claim 134, further comprising: identifying, by the server, timing information associated with the media stream; and transmitting, by the server, the timing information to the client device. ### Claim 143 (depends on 134) The method of claim 134, further comprising: transmitting, by the server to the client device, non-media graphical information of the media stream, the non-media graphical information and a decompressed version of the compressed data set used to generate a media presentation at the client device. ### Claim 144 A system for generation of a media presentation at a client, comprising: a server configured to: receive an indication of a media format supported by a client agent that executes on a client device; and determine, based on the received indication of the media format supported by the client agent, that a media format of a media stream rendered by an application program executing on the server is supported by the client device; and an output filter module executing on the server configured to: monitor the media stream rendered by the application program, the media stream comprising a compressed data set; intercept the compressed data set of the media stream rendered by the application program; and transmitting, from the server, the compressed data set to the client device for decompression by the client device. ### Claim 145 (depends on 144) The system of claim 144, wherein the server is further configured to: establish an operating mode of the server based on the received indication of the media format supported by the client agent. ### Claim 146 (depends on 144) The system of claim 144, wherein the server is further configured to: receive a list of media formats supported by the client agent, the list corresponding to one or more external codecs installed on the client. ### Claim 147 (depends on 144) The system of claim 144, wherein the output filter module is further configured to: monitor calls made to an operating system of the server. ### Claim 148 (depends on 144) The system of claim 144, wherein the output filter module is further configured to: detect a display command from the application program executing on the server. ### Claim 149 (depends on 144) The system of claim 144, wherein the output filter module is further configured to: determine that the media stream generated by the application program comprises a bitmap representation of a non-textual element. ### Claim 150 (depends on 144) The system of claim 144, wherein the server is further configured to: determine that the media stream comprises a decompressed data set; and compress the decompressed data set into a media format supported by the client device. ### Claim 151 (depends on 144) The system of claim 144, wherein the server is further configured to: transmit, to the client device, information for locating images of the media stream on a display screen. ### Claim 152 (depends on 144) The system of claim 144, wherein the server is further configured to: identify timing information associated with the media stream; and transmit the timing information to the client device. ### Claim 153 (depends on 144) The system of claim 144, wherein the server is further configured to: transmit, to the client device, non-media graphical information of the media stream, the non-media graphical information and a decompressed version of the compressed data set used to generate a media presentation at the client device.
