ABSTRACT:
According to the present invention, a method for switching programs in a digital broadcasting is provided. In this method, on a transmission side, a physical channel number for transmitting a program having a program number therethrough is assigned to a part of the program number. On a receiving side, in changing program numbers from a first program number to a second program number, a second physical channel number, for transmitting a second program having the second program number therethrough, is identified based on the second program number; wherein it is determined whether or not the identified second physical channel number is the same as a first physical channel number which is now being received; and wherein if it is determined that the first and the second physical channel numbers are not the same, switching is performed for receiving the physical channel having the identified second physical channel number.
