Video Servers are quickly replacing tape machines in a variety of applications. Enabled by A/V compression, networking and storage, servers have advantages over traditional tape transports. This paper will describe how to evaluate the various server architectures that are in use today. Servers are designed based on four distinct architectures; each method has advantages and trade-offs. The evaluation also includes a discussion on reliable storage, and scalability issues.


Alexander Calder (1898-1976) is considered the artistic father of the Mobile. A Mobile hangs in midair, suspended from a single point. It is composed of individual elements that are in perfect balance with the whole. By way of illustration, let's use the Mobile to understand how to evaluate broadcast products, particularly video servers. Figure 1 shows an example of a Mobile. The Mobile has two distinct sides, both in balance. All of the elements represent either product features (right side) or the manufacture'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.
