Abstract
Abstract A border-type embedded data block is decomposed so that it can be dimensionally characterized by address codes that are applied to the embedded data characters that define its lattice-like synchronization frame. The border-type embedded data block is composed of a self-clocking glyph code pattern. This glyph code pattern may be implemented by slash-like symbols which provide a grayscale appearance when viewed under normal conditions.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
126 words
A process for dimensionally characterizing an embedded data block that has an interior region that is free of embedded data, said process comprising the steps providing a lattice-like synchronization frame of embedded data characters that are on substantially uniform centers edge-to-edge of said embedded data block, including from inside edge-to-outside edge, along a first set of parallel paths and along a second set of parallel paths that are orthogonally oriented with respect to said first set, encoding at least one address code in the embedded data characters on said one set of paths and at least one additional address code in the embedded data characters on said second set, thereby enabling the data block to be dimensionally characterized in decomposed parts that surround said interior region.
Claim 2
Dependent Claim
126 words
A process for dimensionally characterizing an embedded data block that has an interior region that is free of embedded data, said process comprising the steps providing a lattice-like synchronization frame of embedded data characters that are on substantially uniform centers edge-to-edge of said embedded data block, including from inside edge-to-outside edge, along a first set of parallel paths and along a second set of parallel paths that are orthogonally oriented with respect to said first set, encoding at least one address code in the embedded data characters on said one set of paths and at least one additional address code in the embedded data characters on said second set, thereby enabling the data block to be dimensionally characterized in decomposed parts that surround said interior region.
Claim 3
Dependent Claim
18 words
The process of claim 1 wherein said embedded data block is composed of a self-clocking glyph code pattern.
Claim 4
Dependent Claim
28 words
The process of claim 2 wherein said glyph code pattern is composed of slash-like symbols, said symbols being written on said recording medium on substantially uniformly spaced centers.
Claim 5
Dependent Claim
22 words
The process of claim 3 wherein said glyph code pattern has a substantially uniform grayscale appearance when viewed under ordinary viewing conditions.
