In this case, using physical channel bit must be low(0). But if the channel band is ATSC air or ATSC cable, there are two cases that physical channel enable or disable. If the physical channel sending is meaningful, you should set this bit low(0). If the physical channel sending is meaningless, you should set this bit high(1). Example) 1.
