Abstract
Abstract A method in a data processing system for providing content from a distributed database to a client. In a preferred embodiment, a transcoding proxy server receives a request for content from a client machine. The transcoding proxy server retrieves the content from an originating server. The retrieved content is provided in a first format type. In response to a determination that an increase in efficiency would be obtained by allowing the client to process the content in the first format type prior to transcoding the content into a second format type, the transcoding proxy server sends the content to the client in the first format type. Furthermore, in response to a determination that the client does not have content processing software for processing the content in the first format, the transcoding proxy server sends content processing software for the first format type along with the content in the first format type to the client. The transcoding proxy server then transcodes the content from the first format type into the second format type and sends the content in the second format to the client.
