The 7000 indicates a specific encoding system.

The first 0000 is where the modulation wavelength goes. If this works I guess modulation wavelength is ignored here and gotten from the ID.

The 0000 000A together indicate the length of the remainder as being 10 (decimal) pairs of numbers.
The next 0000 is the ID which does a table lookup for information not encoded here. 0000 seems to be the ID for RC5 timing characteristics (without forcing you to use RC5 frame structure).

The 0011 I have no clue.

The 0010 I think is a flag that the whole remainder is a repeating signal.

All the 0002's represent single '1' bits in the IR signal. All the 0001's represent single '0' bits in the IR signal. The 001B is the toggle bit ('0' or '1' depending on whether it is an even or odd press), but I don't know why 001B means that.

The first bit (the first 0002) is always '1' in Streamzap. The second bit is '1' when the command is <64 and '0' when the command is 64..127. The third bit is the toggle.

The next 6 bits "0002 0001 0001 0001 0002 0002" are binary 100011 which is decimal 35 which is the system number and ought to be the same for all commands.

The next 6 bits similarly encode the low six bits of the command number.

The 0000 after that represents the "lead out" burst.

The final 0000 is padding since the number of PAIRS of values is counted.
