Halo ODST > SGP Task Force: 7
J Banner 7
ColdGlider:
I changed my mind. I would like to maintain a topic in Task Force: 7 for each of the "J Banners". This post is a perfect place for discussion on the banner that Dunder Moose provided image links to (now also in the gallery.)
Each of the three banners discovered so far has a unique signature in the fourth column. (They differ elsewhere as well, but that is the first column which differs among all three.) If you decode these columns into binary (Top-Bottom, Little Endian, Dot=1) then you can obtain three unique numbers which can be used to identify the banners easily: 7, 0, 15. This is especially nice since each of the extremes (as well as the number 7!) is represented.
Based on this unique property, I'm naming the banner cataloged by Dunder Moose "J Banner 7" and renaming this topic's subject accordingly. I'm also happily unlocking it.
:)
ColdGlider:
Way back on October 8th I described what I thought would be the required specifications for an analysis tool capable of tackling the binary data we assumed to be contained in the J-Banners. I began writing that tool the other night and the current version allowed me to produce the following data for J Banner 7.
I wanted to catalog the 4-bit values encoded in the banner columns. For each of four possible interpretations, a comma separated list is provided. There are three fields: column index, binary representation, decimal value.
Please note that maintaining Little Endian bit order while changing scan direction (top-bottom / left-right) is functionally equivalent to maintaining the scan direction and altering the endianness.

Dunder Moose:
So I can't program like ColdGlider, but I know how to use Excel a little. Here is a graphic representation of the banners. The composite at the bottom shows the frequency for dots in each position. It seems likely since the codes are so similar that they do not give meaning when concatenated (Unless it is a repetitious phrase). Also by comparing them one to another, each position now has a possibility of 4 values: 0-3. I don't know what that opens up decryption-wise. I got excited when I learned that there is an 8-dot Braille that would match the depth of the banners, but I haven't found a good ascii mapping for it online.

ColdGlider:
Well done, Mr. Moose! The image has been added to our gallery here.
I've often wondered what binary operations on the data (i.e binary AND, binary OR) would produce. Moose's result set provides the equivalent of an AND operation if you convert the blocks equal to 3 to a 1 and the rest of the values to 0. To get the equivalent to an OR operation, you convert all non-zero values to 1. Performing each of these operations produces two "new" sets of banner dots:

I dropped these new data sets into my binary analyzer program and set it to decode ASCII in four different ways. I turned up a big nothing, but am providing the data for proof/reference. I also grouped the data into 7-bit bytes, performed the same eight decodings, and also got nothing. If anyone really wants that data I can provide it as well.
Below are the ASCII conversions of these new sets of dots, assuming 8-bit bytes. Values in brackets ([]) are within the ASCII range but are non-printable. Values in braces ({}) are outside the valid ASCII range. Valid ASCII values are decoded into the corresponding ASCII character.
