A message becomes an image. CVP2 uses the full RGB24 spectrum in original digital files. Landmarks frame the data; independent checks verify the recovered bytes.
Visual carries exact text or file bytes; Lexicon first adds English word addresses and optional concept references.
4,096 × 4,096 pixels. All 16,777,216 RGB colours, once each. This is an address atlas; the global directory tells you which addresses are assigned.
Preparing the full atlas…
Row-major order: n = y × 4096 + x. Red = (n >> 16) & 255; green = (n >> 8) & 255; blue = n & 255; alpha = 255. The original PNG uses exact sRGB channel bytes. Fit view is a scaled preview; inspect coordinates or open the original at 1:1 for individual colours.
The atlas is not a CVP1 message: it has no message header, landmarks, or error correction. CVP1 uses sixteen repeatable transport colours to carry data. A namespace address gains an owner through the global registry.
Every RGB24 value is available: three bytes per data tile, six times CVP1’s gross tile capacity. PNG file-size savings depend on the message. Send the original PNG without resizing or colour conversion.
Auto fit sizes the square from the compressed payload. Frames retain a 12-tile landmark border on each side.
Preparing the first frame…
Original PNGs retain exact colours. Keep the entire square frame and its landmarks.
CVP2 stores three wire bytes in each RGB tile. At one pixel per tile, one data pixel carries 24 bits. Framing, error correction and padding reduce the final message capacity; large messages use verified numbered frames.
A million entries require storage proportional to their size. Compression helps when data repeats; the live frame count shows the actual capacity.
This bench injects wire-byte errors, not optical colour drift. RS(255,223) corrects up to 16 unknown byte errors per block. Beyond that, recovery is not guaranteed; the content hash must still match.
Choose the declared transport. Its versioned header must verify; this reader does not infer the format from the colours.
Choose one image or all the images in a sequence. Order does not matter.
The decoder recognizes the layout from the image itself.
Decoded content is data. This instrument never runs recovered code or renders recovered HTML.
Shared colour space: inspect global reservations · compose lexical / Carrier messages.
CVP2 and CVP1 are outer transports for bytes. CVP2 maps three bytes directly to each RGB24 tile; CVP1 retains its sixteen-colour mapping. Carrier and USL1 retain their existing meaning and message rules.
| Data grid | CVP1 bytes / frame | CVP2 bytes / frame | Default image |
|---|---|---|---|
| 64 × 64 | 1,561 | 10,481 | 352 × 352 px · 4 px/tile |
| 128 × 128 | 6,913 | 42,593 | 608 × 608 px · 4 px/tile |
| 256 × 256 | 28,321 | 171,710 | 1,120 × 1,120 px · 4 px/tile |
| 1,024 × 1,024 | 458,265 | 2,750,705 | 3,144 × 3,144 px · 3 px/tile |

Auto fit selects the smallest multiple-of-eight grid after optional compression. The full 4,096 CVP2 data grid carries 44,015,294 protected stream bytes in a 4,120 × 4,120 image including landmarks. One-pixel tiles are available at every grid. The separate full namespace atlas is 4,096 × 4,096 and contains no message framing.
The fixed header carries the grid, page index and count, byte lengths, compression flag, file name and type, message identity, and SHA-256 fingerprints. The selected decoder checks the in-band magic and version before it accepts a frame.
CVP2 RGB24 Exact: reference codec, specification and release hashes. Read original PNG files as integer RGB samples. The sixfold gain compares gross data-tile capacity, not PNG file size, semantic capacity or optical robustness.
The retained CVP1 executable reference is cvp1/1.2.0/cvp1.js, with its normative specification and release hashes. This standalone embeds that same reference bundle. Its frozen version 1 application notes describe the earlier namespace rules; the current global reservation directory adds an allocation layer without changing CVP1 bytes. Agents can inspect window.CarrierVisual and the embedded ucv1-spec JSON. Where supported, the page also registers structured tools for encoding, reading, and inspecting the protocol.
The paired export contains original PNGs and a manifest linking each frame to exact source bytes, the message hash, page index, palette, and protocol version. The exact source bytes are included as source.bin.
These are reproducible examples for training or evaluation. A model’s visual understanding and decoding accuracy still need to be measured; image encoding alone does not confer either.
