AVB v2.1: Files begin with (hex) byte pattern {{magic|81 00 ?? 00 01 00}}, where the "??" byte is <code>01</code> or <code>02</code>. The next two bytes (offset 6) might always be {{magic|01 00}}, though this is not a signature -- it's a tag for the "Name" chunk that (always?) appears first in the file.

AVB v2.5: Files begin with {{magic|81 81 ?? 00 02 00}}, where the "??" byte is <code>01</code> or <code>02</code>.

BGB v2.5: Files begin with {{magic|81 81 03 00 02 00}}. The byte at offset 7 (the high byte of the first tag ID) might always be <code>01</code>.

All files normally end with bytes {{magic|07 00}}.
