Abstract

There is provided an AV content processing device operable to reduce unpleasantness caused to a user when a detection error occurs in detecting a CM section.

A CM detection unit (101) detects a CM section based on a power level of a sound signal in a stored AV content or the like, and acquires information indicating boundaries between the CM section and program sections. The user inputs, via a purpose reception unit (102), a view purpose to view the AV content. Boundary A boundary correction unit (103) shifts, in accordance with the view purpose inputted by the user, positions of the boundaries (a start point and an end point) between the CM section detected by the CM detection unit (101) and the program sections such that the detected CM section becomes long or short.

an output control unit for determining, when the instruction is received by the first reception unit, the boundary between the program section and the CM section in accordance with the corrected boundary information, and extracting and outputting a section indicated by the instruction.

2. The AV content processing device according to claim 1, wherein

the first reception unit is operable to receive from the user a program output instruction for outputting at least a portion of the program section of the AV content and a CM output instruction for outputting at least a portion of the CM section of the AV content,

the boundary correction unit corrects the content of the boundary information such that the boundary is shifted in the direction for the CM section to be short when the program output instruction is received by the first reception unit, and corrects the content of the boundary information such that the boundary is shifted in the direction for the CM section to be long when the CM output instruction is received by the first reception unit, and

the output control unit extracts and outputs, when the program output instruction is received by the first reception unit, a section indicated as a program section according to the corrected boundary information, and extracts and outputs, when the CM output section is received by the first reception unit, a section indicated as a CM section according to the corrected boundary information.

3. The AV content processing device according to claim 2 further comprising a second reception unit for receiving from the user a skip instruction for skipping a portion of the AV content being outputted by the output control unit, wherein,

when the skip instruction is received by the second reception unit during an output of the AV content between a boundary indicating a start point of a CM section according to the boundary information not corrected and a boundary indicating a start point of the CM section according to the boundary information having been corrected, the output control unit causes the output of the AV content to be skipped to an end point of the CM section according to the boundary information having been corrected, and, when the skip instruction is received by the second reception unit during an output of the AV content between a boundary indicating an end point of the CM section according to the boundary information not corrected and a boundary indicating the end point of the CM section according to the boundary information having been corrected, causes the output of the AV content to be skipped to the end point of the CM section according to the boundary information not corrected.

4. The AV content processing device according to claim 1 further comprising a detection unit for calculating a parameter indicating characteristics of one of a sound and an image in the AV content and detecting a section for which the parameter satisfies a predetermined condition as a characteristic section, wherein

the reception unit is operable to receive from the user a characteristics output instruction for extracting and outputting the characteristic section in the program section,

5. The AV content processing device according to claim 1 further comprising a detection unit for calculating a parameter indicating characteristics of one of a sound and an image in the AV content and detecting a section for which the parameter satisfies a predetermined condition as a characteristic section, wherein

the reception unit is operable to receive from the user a characteristics output instruction for extracting and outputting the characteristic section in the program section,

6. The AV content processing device according to claim 1, wherein

the acquisition unit further acquires CM number information indicating a number of CMs in the CM section and length information indicating a length of the CM section, and

the boundary correction unit selects an amount of shift performed for a boundary indicating a start point and boundary indicating an end point of the CM section, based on the CM number information and length information for the CM section.

7. The AV content processing device according to claim 1, wherein the boundary correction unit selects an amount of shift performed for a boundary indicating a start point and boundary indicating an end point of the CM section, based on a length of a program section immediately before the CM section.

8. The AV content processing device according to claim 1, wherein the boundary correction unit selects an amount of shift performed for a boundary indicating a start point and boundary indicating an end point of the CM section, based on a ratio of a length from a start of the AV content to the CM section to a length of the entire AV content.

9. The AV content processing device according to claim 1, wherein the boundary correction unit corrects, when a predetermined condition is satisfied for the CM section, the boundary information such that a boundary indicating a start point and boundary indicating an end point of the CM section are erased.

10. The AV content processing device according to claim 1 further comprising a program information acquisition unit for acquiring program information which is information concerning a program included in the AV content, wherein
