Everyone knows that memory size in a settop box does matter. What most people don’t know is that memory configuration, type, and architecture are key factors in deploying successful digital services. Memory capability within a set-top is a complicated and varied proposition. Many customers of set-top boxes may not fully comprehend the critical deployment of multiple memory types and advanced application requirements when evaluating purchasing decisions. Quite simply, memory configuration in the box affects the performance and the price. We believe the decision-makers need to understand when the technology is worth their dollar. We propose that readers may want to learn a bit more about memory models offered in set-tops before they conclude that the only difference in set-top boxes is the price. We intend to discuss the ways in which memory architecture can be designed for optimal efficiency and economy in a set-top box, why it matters to today’s customer, and how it can affect tomorrow’s service offerings.
