A ‘scoped’ reference model

1. A ‘scoped’ reference model Adam Goldberg Sharp Laboratories of America March 5, 2003

2. ‘scoped’? • There are two ways of looking at the problem: • “Let’s look at the analog connection between ‘a’ and ‘b’ ” • “Let’s look at the end-to-end system, including system-wide issues and similar, but digital, connections” • This ‘scoped’ reference model is focused on the analog reconversion inter

3. Vision for Model • A concise drawing showing the minimum system that demonstrates the problem • Generic boxes, lines and arrows that allows us to talk about the problem specifically • Without jumping into ‘solution space’

5. Key Concepts • Two Devices shown • Source Device • At input: digital content with rights information • Inside: content and rights, separated or not • At output: analog content with rights information • Sink Device • At input: analog content with rights information • Inside: content and rights, separated or not • At output: digital content with rights information

6. Key Concepts (cont) • Not shown • Upstream rights insertion points • Digital interconnect between Source & Sink • Analog pass-through Sink • Where/how/if rights are: separated from content, extracted, converted • Where/how/if content is: compressed, transcoded, sliced/diced/julienned, etc.
