Audio reproducing apparatus and audio reproduction control method for use in the same
First Claim
1. An audio reproducing apparatus that reproduces audio data to be reproduced in sync with video data, comprising:
- a communication device configured to execute communication with another apparatus that reproduces the video data;
a unit configured to detect an amount of an error between a reproduction point of the video data in said another apparatus and a reproduction point of the audio data in the audio reproducing apparatus by making use of the communication executed by the communication device with said another apparatus;
a unit configured to detect, from a stream of the audio data, an audio data time period of audio data with a sound volume level lower than a specified value; and
a unit configured to alter a reproduction speed of the audio data belonging to the detected audio data time period, on the basis of the detected amount of the error in reproduction point.

Abstract
An audio reproducing apparatus reproduces audio data to be reproduced in sync with video data. The audio reproducing apparatus includes a communication device configured to execute communication with another apparatus that reproduces the video data, a unit configured to detect an amount of an error between a reproduction point of the video data in the other apparatus and a reproduction point of the audio data in the audio reproducing apparatus by making use of the communication executed by the communication device with the other apparatus, a unit configured to detect, from a stream of the audio data, an audio data time period of audio data with a sound volume level lower than a specified value, and a unit configured to alter a reproduction speed of the audio data belonging to the detected audio data time period, on the basis of the detected amount of the error in reproduction point.

10. An audio reproduction control method for controlling a reproduction operation of an audio reproducing apparatus that reproduces audio data to be reproduced in sync with video data, comprising:
-
executing communication with another apparatus that reproduces the video data, thereby detecting an amount of an error between a reproduction point of the video data in said another apparatus and a reproduction point of the audio data in the audio reproducing apparatus;
detecting, from a stream of the audio data, an audio data time period of audio data with a sound volume level lower than a specified value; and
altering a reproduction speed of the audio data belonging to the detected audio data time period, on the basis of the detected amount of the error in reproduction point. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
