the synchronizing signal is controlled by frame synchronization.
4. The receiving apparatus of claim 1 , wherein
the transmission signal contains Transmission and Multiplexing Configuration Control (TMCC) information as transmission parameter information, and
the synchronizing signal is controlled by TMCC synchronization.
5. The receiving apparatus of claim 1 , wherein
the synchronizing signal is controlled by Automatic Frequency Control (AFC) synchronization.
6. The receiving apparatus of claim 1 , further comprising:
a synchronizing signal synthesizer connected between the synchronization detector and each of the first receiver and the second receiver, the synchronizing signal synthesizer synthesizing a synchronizing signal, wherein
the synchronizing signal synthesizer performs the synthesis of the synchronizing signal in normal times and stops the synthesis during the channel search.
7. A receiving apparatus for receiving a transmission signal having a synchronizing signal and a broadcaster name information for each transmission channel, the receiving apparatus comprising:
a first receiver;
a second receiver;

a single synchronization detector connected to the first receiver and the second receiver, the synchronization detector performing synchronization determination;
an error corrector connected to the received signal synthesizer, wherein the error corrector corrects an error portion of the received signal received from the received signal synthesizer;
a decoder connected to the error corrector;
a display connected to the decoder;
a broadcaster name acquirer connected to the decoder; and
a memory connected to the broadcaster name acquirer,
wherein the receiving apparatus performs a channel search by making the synchronization detector perform the synchronization determination using the synchronizing signal of at least one of the first receiver and the second receiver.
8. The receiving apparatus of claim 7 , wherein
the transmission signal has a frame format containing a sync word, and
the synchronizing signal is controlled by frame synchronization.
9. The receiving apparatus of claim 7 , wherein
the transmission signal contains Transmission and Multiplexing Configuration Control (TMCC) information as transmission parameter information, and
the synchronizing signal is controlled by TMCC synchronization.
10. The receiving apparatus of claim 7 , wherein
the synchronizing signal is controlled by Automatic Frequency Control (AFC) synchronization.
11. A receiving apparatus for receiving a transmission signal having a synchronizing signal, the receiving apparatus comprising:
