Abstract:
1. A receiver for terrestrial digital television broadcasting comprising: a receiving circuit for receiving terrestrial digital television broadcasting to output a video signal and an audio signal of a predetermined channel and an information signal of information related to a channel being received; a data table in the receiving circuit on which channel data for selecting channels of the terrestrial digital television broadcasting is registered; and a control circuit configured such that: first data for identifying a channel, second data for identifying a broadcast service area and third data for identifying a transport stream are taken out of the information signal to be supplied to the control circuit, if the first data is normally obtained, the receiving circuit selects a channel based on the first data with reference to the data table, and if the first data is not normally obtained, the receiving circuit selects a channel based on the second and the third data with reference to the data table, wherein when a first channel is being received, the receiver moves to a new broadcast service area, a channel in the new broadcast service area is to be selected, and the first data is not normally obtained, the control circuit selects a channel in the new broadcast area by forming a list of groups having the same second data and third data as the first channel and selects a group for which an associated channel matches the first channel, and wherein when no group is associated with a channel that matches the first channel, the control circuit initiates display of a message indicating failure in reception of the same channel.
