Decode Smartwares SH5-TDR-F remote

[akemper]

Hi,

I want to expand sources to decode also signals from SH5-TDR-F remote with self-learning receivers. I started capturing the received signal. It consists of eight identical, sequential bursts as illustrated in the attached picture. While the overall timing and leading sync pulse are pretty obvious, I don't understand how the individual bits itself are encoded.

The total of 32, constant-length low periods suggest 32 bits being encoded in every burst, but I have no clue how this maps to either one, two or three toggling pulses in-between these. Furthermore, there is always one more "one-toggle" as compared to the "three-toggles", thus ensuring a constant length of the overall burst. Anybody having either a good hint or even better understanding how the individual bits might be encoded?

Thx Andreas
