Video display device and method for operating the same

1. A video display device configured to play contents comprising audio, the video display device comprising:

a controller; and

a display configured to display the contents,

wherein the controller is configured to:

receive a request for a condensed version of the contents,

obtain a condensing criterion as a reference for outputting a condensed version of the contents,

wherein the condensing criterion comprises at least a specific word, a name of a main character, an original sound track, a sound effect or a voice print of an actor,

obtain a condensing criterion characteristic information included in a condensing criterion characteristics information database or in a storage unit of the video display device, which is an audio characteristics information, corresponding to the obtained condensing criterion, wherein the condensing criterion characteristic information is for identifying portions of the contents that match the condensing criterion,

extract characteristic information from a specific section of the contents,

wherein the specific section is a comparison section of the contents that is to be compared against the condensing criterion characteristics information that includes at least one sample of audio content;

determine a degree of similarity between the characteristics information and the condensing criterion characteristics information based on one or more audio parameters,

obtain at least one of indexes which respectively indicates the specific section as being a target output for the condensed version of the contents if the extracted characteristic information is matched with the obtained condensing criterion characteristic information, and

edit the contents based on the audio characteristics information by analyzing the contents to identify a plurality of portions of the contents, retaining at least a first portion of the plurality of portions if the degree of similarity exceeds a certain reference value and discarding at least a second portion of the plurality of portions if the degree of similarity undershoots a certain reference value in order to output the condensed version.

2. The video display device of claim 1 , wherein the controller is further configured to extract information regarding at least one of a genre, a name of the leading actor/actress, the name of a main character, or an original sound track for a specific broadcast program from electronic program guide (EPG) information and obtain the condensing criterion based on the extracted information.

3. The video display device of claim 1 , wherein the controller is further configured to receive the condensing criterion from a user.

4. The video display device of claim 1 , wherein the controller is further configured to employ trick mode based on the audio characteristics information in order to output the condensed version.

5. The video display device of claim 4 ,

wherein the controller is adapted to employ the trick mode based on the audio characteristics information by:

analyzing the contents to identify a plurality of portions of the contents;

identifying at least a first portion of the plurality of portions, the at least a first portion having characteristics information similar to the audio characteristics information;

identifying at least a second portion of the plurality of portions, the at least a second portion lacking characteristics information similar to the audio characteristics information;

playing the at least a first portion at a first speed; and

playing the at least a second portion at a second speed faster than the first speed.

6. The video display device of claim 1 , wherein the controller is further configured to execute skip playing of the contents based on the audio characteristics information in order to output the condensed version.

7. The video display device of claim 6 ,

wherein the controller is adapted to execute the skip playing based on the audio characteristics information by:

analyzing the contents to identify a plurality of portions of the contents;

identifying at least a first portion of the plurality of portions, the at least a first portion having characteristics information similar to the audio characteristics information;

identifying at least a second portion of the plurality of portions, the at least a second portion lacking characteristics information similar to the audio characteristics information;

playing the at least a first portion; and

skipping play of the at least a second portion.

8. The video display device of claim 1 , wherein the controller is further configured to control the display to display a progress bar for annotating the condensed version.

9. A method of operating a video display device to play contents comprising audio, the method comprising:

receiving a request for a condensed version of the contents;

obtaining a condensing criterion as a reference for outputting a condensed version of the contents,

wherein the condensing criterion comprises at least a specific word, a name of a main character, an original sound track, a sound effect or a voice print of an actor,

obtaining a condensing criterion characteristic information included in a condensing criterion characteristics information database or in a storage unit of the video display device, which is an audio characteristics information, corresponding to the obtained condensing criterion, wherein the condensing criterion characteristic information is for identifying portions of the contents that match the condensing criterion,

extracting characteristic information from a specific section of the contents,

wherein the specific section is a comparison section of the content that is to be compared against the condensing criterion characteristics information that includes at least one sample of audio content;

determine a degree of similarity between the characteristics information and the condensing criterion characteristics information based on one or more audio parameters,

obtaining at least one of indexes which respectively indicates the specific section as being a target output for the condensed version of the contents if the extracted characteristic information is matched with the obtained condensing criterion characteristic information, and

edit the contents based on the audio characteristics information by analyzing the contents to identify a plurality of portions of the contents,

retaining at least a first portion of the plurality of portions if the degree of similarity meets or exceeds a certain reference value and discarding at least a second portion of the plurality of portions if the degree of similarity undershoots a certain reference value in order to output the condensed version.

10. The method of claim 9 , further comprising:

extracting information regarding at least one of a genre, a name of the leading actor/actress, the name of a main character, or an original sound track for a specific broadcast program from electronic program guide, EPG, information

and obtain the condensing criterion based on the extracted information.

11. The method of claim 9 , further comprising

receiving the condensing criterion from a user.
