SIGNAL ENCODING METHOD AND DEVICE |
摘要 |
A signal encoding method and device are disclosed. The method includes, when an encoding manner of a previous frame of a currently-input frame is a continuous encoding manner, predicting a comfort noise that is generated by a decoder according to the currently-input frame when the currently-input frame is encoded into an SID frame, determining an actual silence signal, determining a deviation degree between the comfort noise and the actual silence signal, determining an encoding manner of the currently-input frame according to the deviation degree, and encoding the currently-input frame according to the encoding manner of the currently-input frame. It is determined, according to the deviation degree between the comfort noise and the actual silence signal, that the encoding manner of the currently-input frame is the hangover frame encoding manner or the SID frame encoding manner, which can save communication bandwidth. |

1. A signal encoding method, comprising:
when an encoding manner of a previous frame of a currently-input frame is a continuous encoding manner, predicting a comfort noise that is generated by a decoder according to the currently-input frame when the currently-input frame is encoded into a silence descriptor (SID) frame, and determining an actual silence signal, wherein the currently-input frame is a silence frame; determining a deviation degree between the comfort noise and the actual silence signal; determining an encoding manner of the currently-input frame according to the deviation degree, wherein the encoding manner of the currently-input frame comprises a hangover frame encoding manner or an SID frame encoding manner; and encoding the currently-input frame according to the encoding manner of the currently-input frame. |
