When multiple threads have shared access to the same data/hardware, the threads can interfere with one another.
1. 如果你用的是USB 遙控器, USB 遙控器的硬體和電視卡硬體無關,
所以不會有"兩個Thread同時Access硬體的問題"
2. 軟體寫對(使用Semaphore, Critical Section Mutex, InterLock 等方式),
也不會有"兩個Thread同時Access硬體的問題"
3. 搖控器軟體用一個CPU, 也不會有"兩個Thread同時Access硬體的問題",
