Method and apparatus for networked information dissemination through secure transcoding

A wherein agent and network media to the multimedia data end of the code conversion, it does not destroy the end-to-end safety ensuring consistency between datum method and system. In one embodiment, a content provider disassembling data stream multiple element, each device may encrypted. A determining orders data unit in a best embodiment, the medium or a proxy shaft according to each associated device is not encrypted, and discards the predetermined device by dividing precedence, wherein realizes the code conversions of the element, and no need to the decryption device. A determining orders data unit and better is each the bumps are arranged isolated or opposite importance/and thus, which is useful to the code conversion image processing. Destination/client device of energy and then to the decryption device and methods for assembling a code conversion proxy transmitting and second for manually content data.
