Video record processing portion 10 has digital tuning portion (tuner) 11, audio signal decoder (decoder) 12, climax test section 13, recording medium 14 and recording medium interface 15 constantly.

Digital tuning portion 11 carries out the reception of audio frequency and video broadcast singal and handles, and also promptly receives the audio frequency and video broadcast singal and carries out detection, is demodulated to MPEG2-TS.

Audio signal decoder 12 is obtained audio signal from the AV signal of being imported, and the audio compression signal (AdvancedAudio Code below is called AAC) that also is about to contain in the AV signal of 11 demodulation of digital tuning portion is transformed into audio signal.

Climax is test section 13 constantly, in the performance number of the audio signal that audio signal decoder 12 is obtained, in the moment with the performance number that satisfies specified criteria, detects constantly as climax.

Specifically, climax is test section 13 constantly, the moment that has the performance number that becomes peak value in the audio signal with 12 conversion of audio signal decoder, detect constantly as climax, and through recording medium interface 15, performance number (peak value) with in this climax moment and this climax moment (peak) is recorded in the recording medium 14 as the climax time information.

With reference to Fig. 2 (a) and Fig. 2 (b), to climax constantly test section 13 climax constantly detection/the recording processing of (peak) and this climax performance number (peak value) in constantly describe.

Fig. 2 (a) shows power (amplitude) curve of audio signal, and Fig. 2 (b) shows the performance number of the audio signal that has been quantized in the power curve of audio signal.

Shown in Fig. 2 (b), climax is test section 13 constantly, from beginning the performance number of comparing audio signal successively at first, at performance number Pi sometime, during greater than the performance number in other moment in certain peak value retention time (for example 20 seconds) T1 after this, in the moment (peak) with above-mentioned performance number Pi (peak value) and this peak value Pi, be recorded as climax time information (with reference to Fig. 3).

Equally, climax is test section 13 constantly, after this also performance number of the performance number Pi in surpassing sometime, under the situation that in back to back certain peak value retention time T1, does not have to occur, with moment of above-mentioned performance number Pi as climax constantly, write down above-mentioned climax relevant climax time information (performance number Pi and climax are constantly) constantly.

Climax test section 13 is constantly proceeded above-mentioned climax detection/recording processing constantly, up to user's shut-down operation, or the end of 1 AV signal (content).

Its result in the recording medium 14, writes down a series of climax (abstract scene candidate) and peak value constantly to each AV signal, as the climax time information as shown in Figure 3.

Recording medium 14, constitute by the hard disk of the AV signal crossed of record digital compression or DVD etc., recording medium interface 15 is used for reading AV signal and climax time information to recording medium 14 record audio vision signals and climax time information (aftermentioned) from recording medium 14.

In addition, Regeneration Treatment portion 20 has AV signal decoder 21, abstract scene extraction unit 22, regeneration control part 23, loud speaker 24 and monitor (monitor) 25.

AV signal decoder 21 is used for taking out the AV signal that the digital compression that write down in the recording medium 14 is crossed, and is demodulated to vision signal and audio signal.

Abstract scene extraction unit 22, from climax constantly test section 13 detected climaxes select given number constantly climax constantly, selected climax is extracted out predefined given abstract scene constantly cut AV signal in the time, as abstract scene.

Specifically, abstract scene extraction unit 22, the individual above-mentioned high tide of the abstract scene number of only selecting to regenerate in the recovery time at given summary (for example 10 or 29).

In addition, abstract scene extraction unit 22 generates the playlist (with reference to Fig. 4) that comprises the abstract scene of extracting out to some extent, and exports to regeneration control part 23.

As shown in Figure 4, in the playlist,, listed the information of definite corresponding climax abstract scene constantly according to peak order early.Particularly as shown in Figure 4, associative memory has the climax reproduction position of (peak) and the abstract scene in the corresponding above-mentioned climax moment constantly in the playlist.

Here, the reproduction position of abstract scene is by the predefined given abstract scene time of cutting stipulates constantly to climax.

Abstract scene extraction unit 22 is set the regeneration starting position and the regeneration ending position of above-mentioned abstract scene, make recovery time of corresponding climax abstract scene constantly, for the above-mentioned climax of clamping constantly the abstract scene of (peak) cut time T.

In addition, in the present embodiment, abstract scene is cut time T be made as and equal peak value retention time T1, but the present invention is not limited in this situation, abstract scene can also be cut time T and be set at different with peak value retention time T1.

The abstract scene that 23 pairs of abstract scene extraction units 22 of regeneration control part are extracted out is regenerated.

Specifically, regeneration control part 23, the playlist according to abstract scene extraction unit 22 is extracted out reads corresponding AV signal through recording medium interface 15 from recording medium 14, allows AV signal decoder 21 regenerate.

Regeneration control part 23 is after abstract scene extraction unit 22 receives as shown in Figure 4 playlist, with what write down in this playlist is that the abstract scene of benchmark cuts the AV signal in the time T with the peak, according to peak order early, read successively from recording medium 14, and send to AV signal decoder 21 and regenerate.

Consequently, regeneration control part 23, can be to the abstract scene of the AV signal that write down in the recording medium 14, individual high moisture capacity the higher person (also being that performance number is bigger) of the capable of regeneration number of institute in summary recovery time that begins to regenerate predetermined successively from the outset, even long AV signal also can its excellent part (highlight) of automatic regeneration.

Also be, as shown in Figure 5, regeneration control part 23 can corresponding audio signal each of peak value P1～P4, with the AV signal in front and back certain hour (abstract scene the cuts the time) T of this peak of clamping P1～P4, D1～D4 regenerates successively as abstract scene respectively.

In addition, in the present embodiment, be provided with type specifying part 27 in the abstract scene extraction unit 22, as shown in Figure 6, the type that can specify the AV signal that should regenerate is the situation of football, and perhaps the type of the AV signal that should regenerate is the situation of baseball etc.

Here, abstract scene cuts the time, can be corresponding to the type of AV signal, be set at make climax be positioned at constantly abstract scene cut the time in the middle of constantly before or after.In addition, type is by the specified kind of passing through the program that AV signal broadcasts such as electronic program guide (EPG:Electronic Program Guide).

For example, type in the AV signal that should regenerate is under the situation of football, comprise from the attacking and defending before scoring to the moment of scoring in order to bear again, until after spectators' appearance, can be as shown in Figure 6, abstract scene is cut the more than half of time, be set at the climax moment (peak value) before.In addition, type in the AV signal that should regenerate is under the situation of baseball, in order to regenerate from the result of bowler's pitching, batter batting is the greatly delighted of spectators on the track that jumps of hommer, this batting and even the grandstand, can be as shown in Figure 6, abstract scene is cut the more than half of time, be set at the climax moment (peak value) before.

In addition, can also allow the spectator abstract scene can be cut the time, be made as from the moment of climax before which second constantly, thus can be corresponding to the type of the AV signal that should regenerate, the manual adjustment abstract scene.

Loud speaker 24 is in order to regenerate from the audio signal of AV signal decoder 21, and with its output, and monitor 25 is in order to regenerate from the vision signal of audio frequency and video decoder 21 and with its output.

At first, contrast Fig. 7 describes the video record processing in the video record processing portion 10 of the associated video record regenerator of the 1st execution mode of the present invention.

Among the step S101, digital tuning portion 11 receives the AV signal that for example digital broadcasting sends and carries out detection, is demodulated to MPEG2-TS.

Among the step S102, the audio compression signal (AAC) that contains in the signal of audio signal decoder 12 with 11 demodulation of digital tuning portion is transformed into audio signal.

Among the step S103, climax moment test section 13 as mentioned above, the audio signal of 12 conversion of audio signal decoder is carried out climax time information recording processing, by detecting climax (peak) and this climax performance number (peak value) constantly constantly like this, record successively in the recording medium 14 through recording medium interface 15.

Among the step S104, the AV signal that 11 demodulation of digital tuning portion and digital compression are crossed also records in the recording medium 14 through recording medium interface 15.

Here, contrast Fig. 8 is elaborated to the climax time information recording processing among the step S103.

Among the step S1, climax is test section 13 initializing sets " Pj=0 " constantly, as the climax initial value of the performance number of candidate constantly.

Climax is test section 13 constantly, obtains the performance number Pi of each sampling instant in step S3 successively, and the performance number Pj with obtained performance number Pi and climax moment candidate among the step S5 compares.

Afterwards, if the performance number Pi side that newly obtains greater than the climax performance number Pj of candidate constantly, just climax constantly test section 13 with climax constantly the performance number Pj of candidate replace with the performance number Pi (step S7, S9) that newly obtains.

Afterwards, after the replacement of this new climax candidate performance number is constantly finished, climax test section 13 constantly will be reset to 0 at this moment in the elapsed time, and the performance number Pj to new climax moment candidate restarts the later processing of step S3 (step S11).

In addition, if from climax the going out now of performance number Pj of candidate constantly, between the certain peak value retention time T of process, the climax moment candidate (step S13) that the performance number Pi bigger do not occur than the performance number Pj of climax moment candidate, climax constantly test section 13 is recorded as climax time information (step S15) just with this climax moment and this performance number Pj of the performance number Pj of candidate constantly.

Like this, in case find climax constantly, climax test section 13 constantly just is reset to initial condition (step S17, S1) with the performance number Pj of climax moment candidate, restarts the later processing of step S3.

Next contrast Fig. 9, the summary Regeneration Treatment of the Regeneration Treatment portion 20 of the videograph regenerating unit of present embodiment is described.

Abstract scene extraction unit 22, the climax time information (with reference to Fig. 4) that is write down in the read-out recording medium 14 in step S201 among the step S202, begins to be chosen as successively abstract scene with climax constantly from the higher side of peak value.

Among the step S203, abstract scene extraction unit 22 generates and to include abstract scene with the climax playlist of (peak) and the regeneration range of abstract scene constantly as shown in Figure 4, exports to regeneration control part 23.

In addition, AV signal decoder 21, the AV signal that in step S204, is write down in the read-out recording medium 14, among the step S205, corresponding to the indication from regeneration control part 23, regeneration is to the abstract scene of the AV signal of being read.
