[jry-king]

This page is actually talking about how to decide whether some bits represent a frame or actual data, and it also introduces a simple method in which a bit pattern is chosen to represent frame. Hope this hint is helpful:)
By the way it's so interesting to submit issue to others' repo. After all we don't have many such chances for now. (Why do I feel I'm going to see this issue on Qzone?)
