ABSTRACT

The mobile (Alexander Calder, 1898-1976) hangs in midair, suspended from a single point. Let us use the mobile as a guideline for evaluating broadcast products, particularly the video server.

Figure J.1 shows an example of a mobile illustrating the values of a video server. All of the elements represent either product features (right side) or the vendor’s values (left side). The left side represents the extrinsic (outside the product) value of a product, and the right side represents the intrinsic (inside the product) value of a product. The combination of the extrinsic plus intrinsic values is the total value of a product and should equate the product’s price.
