Abstract

A system for dynamically transcoding data transmitted between computers is implemented in an apparatus for use in transmitting data between a network server and a network client over a communications link. The apparatus includes a parser coupled to a transcode service provider. The parser is configured to selectively invoke the transcode service provider in response to a predetermined selection criterion.

Claims

1. A method for providing a network client with a data object residing on a network server, said method comprising:

receiving a request for a data object from the network client;

retrieving the requested data object from the network server;

determining whether the data object includes content created with an unauthorized software product, said determination comprising scanning the data object for a predetermined code associated with an authorized software product;

selectively transcoding the data object according to a predetermined selection criterion in response to said determination; and

providing the transcoded data object to the network client.

2. The method of claim 1, wherein said step of selectively transcoding the data object further comprises adding a message to the data object corresponding to said detection of content created with an unauthorized software product.

3. A method for providing a network client with a data object residing on a network server, said method comprising:

receiving a request for a data object from the network client;

retrieving the requested data object from the network server;

determining whether the data object includes textual content meeting a predetermined selection criterion, said determination comprising scanning the data object for text written in a specified language;

selectively transcoding the data object in response to said determination; and

providing the transcoded data object to the network client.

4. The method of claim 3, wherein said step of selectively transcoding the data object comprises translating text written in the specified language to a different language.
