g. After the bit stream is set, 2-byte boundary marks are respectively added at two ends, and the length of the whole compressed data packet is increased after the start of the marks, so that the compressed data packet is isolated in storage, and the integrity of the compressed data packet is verified after transmission.
h. A set of data is additionally provided for recording the setting parameters in step 1. If dynamic adaptation is required, the data should be dynamically adjusted along with the compression process, and the parameter set corresponding to the initial position of the original data is recorded.
i.
