Block formating

All blocks are formated using Key / Length / Value. Key is 16 bits long. It's the block type. Length is a variable size field using the same values as matroska : bits, big-endian 1xxx xxxx - value 0 to 27-2 01xx xxxx xxxx xxxx - value 0 to 214-2 001x xxxx xxxx xxxx xxxx xxxx - value 0 to 221-2 0001 xxxx xxxx xxxx xxxx xxxx xxxx xxxx - value 0 to 228-2 ... The length is the size of the block in bytes, including the key and size fields. So the minimum length of a block is 3. The value is the block content. Its size can be 0.

Field length (bits) Value
Key 16 "EX"
Length n * 8, 0 < n < inf 0x1A
Value Lentgh * 8 "exemple"
