A DTV signal has a plural-data-segment frame header including complementary first and second ghost-cancellation reference signals differentially delayed by the duration of two NTSC horizontal scan lines. The single chip low-power analog front end produces digitized CCD data in either 13-bit, 12-bit or 10-bit formats at a first current level and 9-bit, 8-bit, or 6-bit formats at a second current level. The invention also relates to methods for producing a soybean plant containing in its genetic material one or more transgenes and to the transgenic soybean plants and plant parts produced by those methods. No unthreaded portion of the anchor extends above the lower reference surface by more than a second amount that is generally selected to be equal to the actual thickness of the framing member, so as to ensure that no substantial unthreaded portion of the anchor can extend above that member. A method for cleaning a streamer includes towing the streamer through the water. In the method, the embossed pattern is formed from a number of flute portions oriented at an angle to each other and an intersection of these, the intersection and all the flute portions extending from it to a distance from the intersection being produced in a single embossing operation.
