During a GameShare session, the guest console sends its touch control data to the host console every 4ms, and motion/mouse control data every 5ms. To counteract network packet losses—which can result in inaccurate/missed inputs—the guest sends the accumulated delta time and movement amount to the host (img below); the host subtracts the previous total to reconstruct true movement in this cycle, thus recovering any lost input.
There’s also a touch specific problem: A “touch release” can be lost with a packet. To prevent this, the guest sends a touch release count to the host along with the control data; the host resets the accumulated time whenever the count rises, thus recovering any lost touch releases (img below).
