DRD is a binary format used by DrDepth used to create depth data from recordings.

Basic Structure

The file is a binary file with big endian format. Float values are stored as IEEE 754 floating-point "single format".

The size of the file header is unknown but it rather short and probably around 126 bytes long. It stores probably some unicode encoded track file name and other unknown information.

After the header a series of frames follows with a size of 48bytes
