Transcoding is the direct digital-to-digital conversion of one encoding to another, such as for movie data files, audio files (e.g., MP3, WAV), or character encoding (e.g., UTF-8, ISO/IEC 8859). This is usually done in cases where a target device (or workflow) does not support the format or has limited storage capacity that mandates a reduced file size, or to convert incompatible or obsolete data to a better-supported or modern format.
Method and apparatus for content protection in a personal digital network environment
InactiveUS20050144468A1Easy to disassembleReliable lockingTelevision system detailsUser identity/authority verificationGraphicsVideo processing
In some embodiments, the invention is a personal digital network (“PDN”) including hardware (sometimes referred to as Ingress circuitry) configured to transcrypt encrypted content that enters the PDN. Typically, the transcryption (decryption followed by re-encryption) is performed in hardware within the Ingress circuitry and the re-encryption occurs before the decrypted content is accessible by hardware or software external to the Ingress circuitry. Typically, transcrypted content that leaves the Ingress circuitry remains in re-encrypted form within the PDN whenever it is transferred between integrated circuits or is otherwise easily accessible by software, until it is decrypted within hardware (sometimes referred to as Egress circuitry) for display or playback or output from the PDN. Typically, the PDN is implemented so that no secret in Ingress or Egress circuitry (for use or transfer by the Ingress or Egress circuitry) is accessible in unencrypted form to software or firmware within the PDN or to any entity external to the PDN. Other aspects of the invention are methods for protecting content in a PDN (e.g., an open computing system) and devices (e.g., multimedia graphics cards, set top boxes, or video processors) for use in a PDN.

Enhanced transcoding of structured documents through use of annotation techniques
InactiveUS20030018668A1Digital data information retrievalDigital computer detailsDocumentation procedureTranscoding
Methods, systems, and computer program products for improving the transcoding operations which are performed on structured documents (such as those encoded in the Hypertext Markup Language, or "HTML") through use of annotations. Source documents may be annotated according to one or more types of annotations. Representative types of annotations direct an annotation engine to perform selective clipping of document content, provide enhanced HTML form support, request node and / or attribute replacement or the insertion of HTML or other rendered markup syntax, and direct a transcoding engine to provide fine-grained transcoding preference support (such as controlling transcoding of tables on a per-row or per-column basis). The disclosed techniques may be used with statically-generated document content and with dynamically-generated content. Annotation is performed as a separate step preceding transcoding, and a modified document resulting from processing annotations may therefore be re-used for multiple different transcoding operations.
