Abstract

Disclosed is a method of processing a signal, which includes receiving at least one of a first signal and a second signal, receiving mode information, and coding the at least one of the first signal and the second signal using at least one of a first coding scheme and a second coding scheme according to the mode information, wherein the mode information is information for indicating that a prescribed mode corresponds to which one of at least three modes.

Claims

1. A method of processing a signal, comprising:

receiving mode information including a first frame mode and a second frame mode as information indicating that a prescribed mode corresponds to which one of a first mode, a second mode and a third mode,

wherein if the second frame mode is the first mode, the first frame mode corresponds to one of the first mode and the second mode and

wherein if the second frame mode is the third mode, the first frame mode corresponds to one of the third mode and the second mode.

2. The method of claim 1, wherein the first mode corresponds to the mode for using a first coding scheme, wherein the third mode corresponds to the mode for using a second coding scheme, and wherein the second mode corresponds to the mode for connecting the first mode and the third mode together.

3. The method of claim 2, wherein the second mode includes a forward connecting mode and a backward connecting mode.

4. The method of claim 3, wherein if the second frame mode is the first mode, the first frame mode corresponds to one of the first mode and the backward connecting mode, and wherein if the second frame mode is the third mode, the first frame mode corresponds to one of the third mode and the forward connecting mode.

5. The method of claim 2, wherein the first coding scheme corresponds to a speech coding scheme, and wherein the second coding scheme corresponds to an audio coding scheme.

6. The method of claim 1, wherein the second mode corresponds to the mode for using both of the first coding scheme and the second coding scheme.

7. The method of claim 1, further comprising:

receiving at least one of a first signal and a second signal; and

coding the at least one of the first signal and the second signal using at least one of a first coding scheme and a second coding scheme according to the mode information.

8. An apparatus for processing a signal, comprising a receiving unit receiving mode information including a first frame mode and a second frame mode as information indicating that a prescribed mode corresponds to which one of a first mode, a second mode and a third mode,

wherein if the second frame mode is the first mode, the first frame mode corresponds to one of the first mode and the second mode and

wherein if the second frame mode is the third mode, the first frame mode corresponds to one of the third mode and the second mode.

9. The apparatus of claim 8, wherein the first mode corresponds to the mode for using a first coding scheme, wherein the third mode corresponds to the mode for using a second coding scheme, and wherein the second mode corresponds to the mode for connecting the first mode and the third mode together.

10. The apparatus of claim 9, wherein the second mode includes a forward connecting mode and a backward connecting mode.

11. The apparatus of claim 10, wherein if the second frame mode is the first mode, the first frame mode corresponds to one of the first mode and the backward connecting mode and wherein if the second frame mode is the third mode, the first frame mode corresponds to one of the third mode and the forward connecting mode.

12. The apparatus of claim 9, wherein the first coding scheme corresponds to a speech coding scheme, and wherein the second coding scheme corresponds to an audio coding scheme.

13. The apparatus of claim 8, wherein the second mode corresponds to the mode for using both of the first coding scheme and the second coding scheme.

14. The apparatus of claim 8, the receiving unit further comprises a coding unit receiving at least one of a first signal and a second signal, the coding unit coding the at least one of the first signal and the second signal using at least one of a first coding scheme and a second coding scheme according to the mode information.

15. A method of processing a signal, comprising:

determining mode information including a first frame mode and a second frame mode as information indicating that a prescribed mode corresponds to which one of a first mode, a second mode and a third mode;

if the second frame mode is the first mode, changing the first frame mode into one of the first mode and the second mode; and

if the second frame mode is the third mode, changing the first frame mode into one of the third mode and the second mode.
