Data Block Structure

Note: Data Block 10, the “Image Data” Data Block, has no Data Block Header, no Data Block Footer, and no Data Fields. It only consists of image data.

All other Data Blocks follow the structure described below.

Data Block Header

The start of each Data Block starts with 2x uint32 numbers.

The first number is the length in bytes of this Data Block Header and all the following Data Block fields, (including the last field, Field Type 0.) This length does not include the Data Block Footer.

The second number is currently of unknown significance. It has been observed to be one of: 1, 2, 4, 7, 8.

Data Block Header
Bytes Type Description
0-3 uint32 Data Block Length in Bytes (Header + Fields)
4-7 uint32 Unknown (1, 2, 4, 7, or 8)

Data Block Fields

Following the bytes of the Data Block Header, the fields inside the Data Block are parsed contiguously as normal.

The last field of the Data Block fields is Field Type 0. Field Type 0, Field Len 8 signifies End Of Data Block. This field is only a Field Header–the length of 8 bytes only allows for the length of a Field Header.
