rtp-sn-p
The value of p in RTP SN (RTP Sequence Number) calculation. Least Significant Bits (LSB) encoding is used for
header fields whose values are usually subject to small changes. With LSB encoding, the k least significant bits of the
field value are transmitted instead of the original field value, where k is a positive integer. After receiving k bits, the
decompressor derives the original value using a previously received value as reference (v_ref). The scheme is
guaranteed to be correct if the compressor and the decompressor each use interpretation intervals as follows:

In which the original value resides
And in which the original value is the only value that has the exact same k least significant bits as those transmitted.
The interpretation interval can be described as a function:
f(v_ref, k). Let f(v_ref, k) = [v_ref - p, v_ref + (2^k - 1) - p]
Where p is an integer.
