PURPOSE: A digital broadcasting receiver and its selection method are provided to save the required selection time when a transmission channel is exchanged to select a program. CONSTITUTION: A first receive circuit(2) performs a receiving process in relation to the selection information and program information. A CPU(4) always extracts a parameter requested for program selection from various tables acquired by a first demultiplexer(DMX) in the first receive circuit, and generates the latest database. When a program selecting instruction is input to the CPU, a frequency(parameter A) of the transponder where the program is arranged is acquired from the latest program specific information(PBI) which is acquired by the first DMX, and is set at a second tuner. A video elementary stream(ES) of the program and a packet ID(parameter B, PID) of an audio ES are acquired by the latest PBI of the program. The PID is set at a descrambler and a second DMX. Thereby, the broadcasting receiver, its selection method and the data transmission method can be applied to a digital satellite broadcasting, a digital cable broadcasting, and a digital ground broadcasting. |
