Understanding the Scoped Reference Model: Analog and Digital Connections

DESCRIPTION

This document outlines a scoped reference model focusing on the analog reconversion inter Vision for Model A. It presents a framework to analyze the connection between two devices: a Source Device that processes digital content with rights information and a Sink Device that outputs digital content. Key concepts include the representation of systems with simplified drawings, emphasizing system-wide issues without diving into solutions. The presentation encourages discussions about rights insertion, digital interconnection, and the treatment of content, aiming to clarify the minimum system that illustrates the core problem.

Presentation Transcript

  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’

  4. 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

  5. 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.
