摘要： A Method for pre-processing digital data and in particular of pre-processing digital video and/or digital audio data is provided, wherein a step of encoding (S3) a primary data stream (D1), a step of encrypting (S4) an encoded primary data stream (ED1) and a process of generating (P3) a preview data stream (PD) are built in and/or embedded within a common process (P2) of encoding said primary data stream (D1) in particular by integrating these processes and/or steps within a single and common encoder. The present invention additionally relates to a conversion system (10, 20) having a conversion functionality (11, 21) and a logic functionality (12, 22). Key aspect of the present invention is that said conversion functionality (11, 21) and said logic functionality (12, 22) are embedded in one single and common unit.
