Abstract

A content reproduction apparatus that adopts a content processing method includes a video processor, a video analyzer, and an audio processor for processing audio data and video data input thereto. The video analyzer analyzes video characteristics of video data such as resolutions, compressive distortions, and real frame rates. The video processor processes video data in accordance with video processing, which is determined based on analyzed video characteristics of video data. The audio processor processes audio data in accordance with audio processing, such as dynamic range compression and/or frequency component extension/enhancement, which is determined based on analyzed video characteristics of video data. Thus, it is possible to reproduce sound in an articulate manner depending on the video quality, which is either professional-level video shooting or nonprofessional-level video shooting.

Claims

a video analyzer that analyzes video characteristics of video data; and

an audio processor that processes audio data in accordance with audio processing which is determined based on analyzed video characteristics of video data.

2. The content reproduction apparatus according to claim 1 further comprising a video processor that processes video data in accordance with video processing which is determined based on analyzed video characteristics of video data.

3. The content reproduction apparatus according to claim 1, wherein the video analyzer analyzes video characteristics based on attribute information of video data including at least one of a resolution, a compressive distortion, and a real frame rate, and wherein the audio processor performs audio processing involving dynamic range compression and/or frequency component extension/enhancement.

4. The content reproduction apparatus according to claim 2, wherein the video analyzer analyzes video characteristics based on attribute information of video data including at least one of a resolution, a compressive distortion, and a real frame rate, and wherein the audio processor performs audio processing involving dynamic range compression and/or frequency component extension/enhancement.

5. The content reproduction apparatus according to claim 1, wherein the audio processor determines audio processing based on quality of video data owing to video shooting, detected by the video analyzer, such that audio processing involving intense dynamic range compression and slight extension/enhancement of low frequency components is applied to video data with low quality, audio processing involving intense dynamic range compression and slight extension/enhancement of high and low frequency components is applied to video data with intermediate quality, and audio processing involving intermediate dynamic range processing and intense extension/enhancement of high and low frequency components is applied to video data with high quality.

6. A content processing method comprising:

inputting audio data and video data;

analyzing video characteristics of video data;

specifying audio processing based on analyzed video characteristics of video data; and

processing audio data in accordance with the specified audio processing.

7. The content processing method according to claim 6, wherein at least one of a resolution, a compressive distortion, and a real frame rate is detected from video data as analyzed video characteristics of video data, and wherein the audio processing involves dynamic range compression and/or frequency component extension/enhancement.
