Abstract

An information processing apparatus includes an audio processing unit that performs a predetermined process for an input audio signal, and a power saving control unit that allows the audio processing unit to transition into a power saving state, depending on the length of a silence section in the audio signal.

Claims

1. An information processing apparatus comprising:

an audio processing unit that performs a predetermined process for an input audio signal; and

a power saving control unit that allows the audio processing unit to transition into a power saving state, depending on the length of a silence section in the audio signal.

2. The information processing apparatus according to claim 1, further comprising:

a silence detecting unit that detects a silence section in the input audio signal and generates a power saving control signal including the detection result,

wherein the power saving control unit allows the audio processing unit to transition into the power saving state according to the power saving control signal.

3. The information processing apparatus according to claim 2,

wherein the silence detecting unit generates the power saving control signal that includes the start time and the end time of the detected silence section.

4. The information processing apparatus according to claim 2,

wherein the silence detecting unit selects the power saving state among a plurality of power saving states, depending on the length of the detected silence section and generates the power saving control signal including the selection result.

5. The information processing apparatus according to claim 2,

wherein the silence detecting unit selects, among a plurality of power saving states, the power saving state in which the amount of reduction in power is great as the length of the detected silence section is longer and generates the power saving control signal including the selection result.

6. The information processing apparatus according to claim 2,

wherein the power saving control unit performs a transition process that allows the audio processing unit to transition into the power saving state from a normal state and a restoration process that restores the audio processing unit to the normal state from the power saving state during the silence section.

7. The information processing apparatus according to claim 6,

wherein the silence detecting unit selects, among a plurality of power saving states, the power saving state in which a time necessary for the restoration process is long as the length of the detected silence section is longer and generates the power saving control signal including the selection result.

8. A method for processing information in an information processing apparatus that includes an audio processing unit performing a predetermined process for an input audio signal, the method comprising:

power saving controlling, by the information processing apparatus, that allows the audio processing unit to transition into a power saving state, depending on the length of a silence section in the audio signal.

9. A program that allows a computer to function as:

an audio processing unit that performs a predetermined process for an input audio signal; and

a power saving control unit that allows the audio processing unit to transition into a power saving state, depending on the length of a silence section in the audio signal.
