Individual probes on micro-arrays are re-scaled and corrected with a set of probe dependent coefficients derived from genomic-DNA hybridization signals. The system includes two transmission lines and transmission terminals coupled to both of the transmission lines. In response a determination that the metadata indicates multimedia content is included in the body of content, one or more processors associate an indicator with a page of the body of content that includes that multimedia content, which indicates that the page includes that multimedia content. According to preferred embodiments of the present invention, the at least one dedicated ports is a port for readingwriting streamed data, such as streaming audio andor video data for example. The contour segment can have a fixed maximum length or a variable length, but the deviation between a contour segment and the pitch values in that segment is limited by a maximum value. It is preferred that the zones act and operate independently from one another.
