1. an enhancing comprises the successive module that contains program flow and contains the method for content of the staggered module of cross-program stream, described program flow is readable independently of one another, in described content, forbid occurring any continuous staggered module, described method comprises a step of handling the original module of described content, so that relevant at least one of at least one original program stream staggered and described original module strengthens program flow, described original program stream comprises the original program unit, and described enhancing program flow comprises the enhancing program unit, an original program unit is relevant with an enhancing program unit, the treating step comprises:

  • If a) described original module is a successive module;

    Whether-check will strengthen program flow and be interleaved to and can cause in the described original module continuous staggered module occurring in described content, and in this case,-described original continuous module is divided into a primary module and at least one continuous separation module,-utilize described continuous separation module to separate described continuous staggered module,If-there be the enhancing program unit relevant with the original program unit of described primary module, it is interleaved in the described primary module,If-exist and the relevant enhancing program unit in original program unit of separating module continuously, it is interleaved to the staggered module that is adjacent to described continuous separation module,B) in other cases, described enhancing program flow is interleaved in the described original module;

    C) in described original program unit, increase a pointer that points to its associated enhancing program unit.
