A random access pointcast video delivery system provides the capability for a viewer to select a video advertisement. The video advertisement is automatically customized responsive to the application of the viewer's video content preferences to a video segment map defining a plurality of video segme
A random access pointcast video delivery system provides the capability for a viewer to select a video advertisement. The video advertisement is automatically customized responsive to the application of the viewer's video content preferences to a video segment map defining a plurality of video segments. The viewer is compensated for the verified apparent viewing of the selected advertisement independently of the purchase of the advertised product or service. Where the advertisement is associated with a credit, the viewing of the advertisement subsidizes the viewer's receipt of other video and communication services. Where a viewing of a video results in a purchase, a deposit in the purchase is automatically escrowed until after the buyer has received satisfactory delivery of the purchase.

The method of claim 4 in which the step of collapsing reduces the scale of the pattern of axially extending holes in positions along the axis of the preform. 6. The method of claim 1 in which the step of collapsing includes applying a drawing force that stretches the preform along its axis for reducing the spacing pattern of the holes. 7. The method of claim 6 including a further step of selecting a transverse section along the axis of the collapsed preform where the spacing pattern of the holes matches the spacing pattern of the optical conveyances within the array of optical conveyances. 8. The method of claim 6 in which the preform is drawn to a constant reduced diameter in a region along its axis and the step of removing the transverse section includes removing a plurality of adjacent transverse sections at the constant reduced diameter. 9. The method of claim 1 in which the step of collapsing includes applying an extruding force that forces the preform through a reducing die for reducing the spacing pattern of the holes. 10. The method of claim 9 in which the step of collapsing includes filling the holes with a material for preserving hole integrity through the extrusion process. 11. The method of claim 9 in which the preform is extruded to a constant reduced diameter in a region along its axis, and the step of removing the transverse section includes removing a plurality of adjacent transverse sections at the constant reduced diameter. 12. The method of claim 1 in which the transverse section of the collapsed preform has a mating surface adjacent to the array of optical conveyances, and further comprising the step of polishing the mating surface along with tips of the assembled fibers. 13. The method of claim 1 in which the step of mounting includes inserting a lens array between the transverse section and the common support of the optical conveyances to improve coupling efficiency between the array of fibers and the array of optical conveyances. 14. The method of claim 1 in which the step of assembling includes securing the assembled fibers within the holes of the transverse section with adhesive. 15. The method of claim 1 in which the step of assembling includes assembling the fibers within the holes prior to the step of collapsing. 16. The method of claim 15 in which the step of arranging the preform includes forming the preform from a material that has a lower transition temperature than the fibers of the array of optical fibers. 17. The method of claim 1 in which the array of optical conveyances is an array of emitters. 18. The method of claim 17 in which the array of emitters includes vertical cavity surface emitting lasers formed on a surface of a wafer that also functions as the common support of the array of lasers. 19. The method of claim 18 in which the step of mounting includes mounting the transverse section of the collapsed preform to the surface of the wafer. 20. The method of claim 19 including the further step of inserting a lens array between the transverse section and the surface of the wafer to improve coupling efficiency between the array of fibers and the array of lasers. 21. The method of claim 1 in which both the array of fibers and the array of optical conveyances are arranged as two-dimensional arrays, and the step of mounting includes individually aligning two of the fibers with two of the optical conveyances for collectively aligning a remainder of the array of fibers with a remainder of the array of optical conveyances. 22. A method of arranging optical fibers in a desired array format comprising steps of: fabricating a preform having an axis and axially extending holes arranged in a predetermined pattern; preparing the preform to a malleable state; applying a cross-sectional reducing force that reduces a scale of the predetermined pattern of holes
