Talk:Piñata Vision barcode/Name bits

Row 2 fields

Assuming the following fields are part of row 2 raises questions about how a 9-character name might be stored in the limited space.

• Wildcard - 2? bits
• Variant - 4 bits
• Name length - 5? bits
• Name - ?? bits
• Obfuscation set - 4 bits

So that's 15 bits out of 64, leaving 49 bits for the name, assuming no other data is also stored here, and there's no additional overhead for the obfuscation.

49 / 9 = 5.4 bits per character.

Is the name packed or compressed somehow? How many characters are actually in the name character set?

Is some of this data actually located in row 1? --FeralKitty (talk) 01:15, 20 November 2010 (UTC)
