Digital converter and method to distribute audio video programs

A digital converter, characterized by comprising:

• a supervising controller;
• a multiplexer, coupled to the supervising controller, receiving a plurality of input streams of a plurality of sources and merging the input streams of the sources into a single data stream, wherein the input streams including a plurality of sections each of which has one or more data fields for storing audio/video program data;
• at least one of a first operational processing block, coupled to the supervising controller, wherein at least one of the first operational processing block is controlled by the supervising controller and decodes the content-protected sections of the input streams in the single data stream selectively to unprotect contents of the selected sections;
• and
• at least one of a second operational processing block, coupled to the supervising controller, wherein at least one of the second operational processing block is controlled by the supervising controller, receives the sections of the single data stream selectively, and applies content protection means to the selected sections of the input streams in the single data stream that require the content protection means to generate processed sections.
