In FIG. 8, steps S30 to S39 indicate steps of the operation flow of the CPU 115 when a program recording reservation is made from the program recording reservation management unit 125. S41 to S43 and S34 to S39 are executed by the CPU 11 when recording is performed in response to a request from the direct operation unit 114.
5 is each step of the operation flow. 8 is a case where program recording is reserved but special recording is not performed. The CPU 115 transmits a recording start signal when the reserved start time comes and a recording stop signal when the end time comes. . In this case, the recording unit is one of the first recording / reproducing unit 111 and the second recording / reproducing unit 112.

Hereinafter, a case where special recording is performed by the apparatus of the present invention will be described. CPU 115 is a program recording reservation management unit 1
It goes to see if there is a reservation in 25 (S30). There are two methods of program recording reservation: an EPG (Electronic Program Guide) and a case where the user manually sets the time and the like. If the special recording is performed (S31), the direct operation unit 1
From 14, the user determines which of the voiceprint determination processing units 118, the image determination processing unit 120, and the melody determination processing unit 122 is to be enabled, and performs, for example, the voiceprint determination of the person A among them If determined (S32), the CPU 115 receives the request signal and reads the data of A in the registration management memory 126 (S33). Then, the data of A read from the registration management memory 126 is transmitted to the selected determination processing unit (S34). For example, if the voiceprint determination processing unit 118 is selected, the voiceprint determination processing unit 118 receives the data of A in S34, reads out a plurality or one data related to A from the voiceprint information storage memory 117, and performs the first recording / reproduction with them. The determination is made with the voiceprint data input and extracted from the unit 111. When the start time of the recording reservation comes due to the program recording reservation (S35-Yes), C
The PU 115 transmits a recording and reproduction start signal to the first recording and reproduction unit 111 (S36). First recording / reproducing unit 1
11 receives a recording and reproduction start signal, and
64, the recording is performed on the recording medium, and at the same time, the voiceprint determination processing unit 1
The image information or the audio information is output (reproduced) to 18. C
PU 115 is a voice print determination processing unit 118, an image determination processing unit 1
20, an output (Hi) signal from the melody determination processing unit 122 is received (S37). The CPU 115 receives this signal and transmits a request signal to be recorded to the second recording / reproducing unit 112. When the output from each processing unit is Low, C
The PU 115 transmits a recording stop signal to the second recording / reproducing unit 112 (S39). When the Hi signal is output again, the CPU 115 receives the Hi signal,
A recording start signal to the recording medium is transmitted to the second recording / reproducing unit 112 (S38). Steps S37 to S40 are repeated many times during the program recording reservation period or during the mere recording period depending on whether the signal is a Hi signal or not. When the end time of the recording reservation comes (S40-Yes), the CPU 115 transmits a recording stop signal to the first recording / reproducing unit 111 and the second recording / reproducing unit 112 (S41).

Next, although there is no program recording reservation, the user can perform special recording using the apparatus while watching the program.
The operation flow of the PU 115 will be described. Direct operation unit 1
At 14, the user determines which judgment processing unit is to be enabled, and the CPU 115 receives the request signal and transmits the request signal to the selected judgment processing unit. (S42). Then, a recording start signal is directly received from the operation unit 114 (S43), and the first
The start signal is transmitted to the recording / reproducing unit 111 (S3
4). Since then, the description is omitted because it is the same as the above.

It is to be noted that a single or a plurality of combinations are conceivable as to which of the determination processing sections is made effective and special recording is performed. The signal output to the second recording / reproducing unit changes depending on the signal received from each determination processing unit by the CPU 115. For example, the CPU 115 executes the voiceprint determination processing unit 118
And the output signal of the image determination processing unit and the output signal of the melody determination processing unit 122, and the logical product (AN
If D) is Hi (1), a recording start signal is transmitted to the second recording / reproducing unit 112 or the voiceprint determination processing unit 118
And the output signal of the melody determination processing unit 122, and if the logical sum (OR) thereof is Hi (1), the second
The recording start signal is transmitted to the recording / reproducing section 112 of the recording apparatus. Thus, the CPU 115 has an arithmetic processing function of determining what kind of signal is to be output in the state of the received signal. The user can easily determine which judgment processing unit is to be enabled by the direct operation unit 114.

As described above, according to the first embodiment, when it is desired to watch all recorded programs of a certain length of time from the beginning,
When the user can play back and view the special recording portion (specific portion) recorded by receiving the Hi signal of the determination processing portion, the user can view it by the second recording and playback portion 112. Can be. Further, what is recorded in the second recording / reproducing unit 112 is stored in the external storage device 104, for example,
If a portable HDD is connected and stored, it is easy to carry desired image information or audio information.

Next, a second embodiment of the present invention will be described. In the first embodiment, two recording / reproducing units, a first recording / reproducing unit 111 and a second recording / reproducing unit 112, are provided, whereas in the second embodiment, one recording / reproducing unit is provided. . The recording / reproducing unit records information in a memory or a recording medium as in the case of the first embodiment. The determination target in each determination processing unit is the data stored in each storage memory and the signal data from the tuner.

FIG. 9 is a block diagram showing an example of the configuration of the second embodiment. In FIG. 9, reference numeral 127 denotes an address management memory, which is a Hi signal and a Low signal output from each processing determination unit.
This is a memory for storing a logical address of the first recording / reproducing unit 111 at the time of a signal. The CPU 115 performs a recording and reproducing process different from the first embodiment.

FIG. 10 shows an operation flow of the CPU 115 in the case of recording in the configuration of FIG. In FIG. 10, S
50 to S57 correspond to S35 in FIG. 8 in the first embodiment.
Steps S41 to S41 are modified and changed. S
The input of 50 is the output of S32 in FIG. CPU115
Sends a recording start signal to the first recording / reproducing unit 111 when the reservation start time comes (S50). First recording / reproducing unit 1
11 receives the request signal and records the image or audio data input from the tuner on the memory or the recording medium (S51). When a Hi output signal is output from the selected determination processing unit (S52-Yes), the CPU 115 reads the logical address of the first recording / reproducing unit 111 at that time. Then, the read logical address is written (stored) in the address management memory 127 (S53), and a recording start signal is transmitted to the first recording / reproducing unit 111 (S54).
The CPU 115 also reads the logical address at the time when the Hi signal is changed to the Low signal (at the end of the Hi signal).

FIG. 11 shows an operation flow of the CPU 115 when performing the special reproduction in the second embodiment. Flows such as rewinding, fast forward, and pause are omitted. First, a request signal to be reproduced is directly received from the operation unit 114, and the CPU 115 transmits a reproduction start signal to the first recording / reproducing unit 111 (S60). When performing special reproduction (S6
1-Yes) reads all the start and end logical addresses of each recording portion read by the CPU 115 at the time of special recording from the address management memory 127, and
11 (S62). In step S63, the number of times of special reproduction is counted once. In S64, special reproduction is started. If all the special recorded parts (N) are reproduced, C
The PU 115 ends the special reproduction. Here, it is assumed that the special reproduction has been completed M times out of N times. Unless all the special reproduction portions are completed, S63 to S65 are repeated. When performing special reproduction again, when the key of the operation unit 114 is directly pressed, the CPU 115 reads the start and end logical addresses of the first recording portion from the address management memory 127, and sends the logical addresses to the first recording and reproduction unit 111. Send According to the second embodiment, S62 to S62 in FIG.
By the step of S63, it is possible to instantly jump to the start of the specially recorded portion for viewing, and if it is normally reproduced, it is possible to see all the recorded content.

Next, a third embodiment of the present invention will be described. FIG. 12 is a block diagram showing a third embodiment of the present invention. Except for the difference in the operation flow of the CPU 115 and the addition of the address management memory 127, it is the same as the first embodiment.

FIG. 13 is a flowchart of the operation in the third embodiment. FIG. 13 is a modification of the steps S36 to S41 in FIG.
13 is the input of S60 in FIG. The CPU 115 transmits only a recording start signal to the first recording / reproducing unit 111 (S60). If there is a Hi output signal from the selected determination processing unit (S61), the CPU 115
Is the first recording / reproducing unit 111 at the time when the Hi signal is received.
Read the logical address (A) of (HDD). In the case of a Low output signal, the control waits until a Hi output signal is output. H
A signal that receives the i signal and then ends the Hi signal, that is, L
first recording / reproducing unit 111 at the time of receiving the ow signal
The logical address (B) of the (HDD) is read. Also, H
The time of the period from i to Low is counted (the time of the logical address (A) is t _A , and the time of (B) is t _B ). C
If the count value of the time reaches the time t _C or more set by the user at the time of receiving the Low signal (S64), the PU 115 causes the first recording / reproducing unit 111 to provide the start logical address (A) and the end logical address (A). A request signal for instructing the position of the logical address (B) and outputting data between (A) and (B) to the second recording / reproducing unit 112 is transmitted (S
65). At the same time, the CPU 115 transmits a recording start signal to the second recording / reproducing unit 112 (S66). If the count value of the time at the time when the Low signal is received is not larger than the time t _C set by the user, the Hi signal is output next, and the process waits until t _C is satisfied. If it is within the recording reservation time, it waits for the Hi signal from the selected judgment processing unit, and thereafter repeats the above procedure.

FIG. 14 is a timing chart based on the operation flow of FIG. In the figure, (a) is a voiceprint determination output, (b) is a determination processing result of the CPU 115, (c) is a recording operation of the first recording and reproducing unit 111, and (d) is a reproduction of the first recording and reproducing unit 111. (E) shows the recording operation of the second recording / reproducing unit 112. (A) shows a case of a voiceprint determination processing unit as an example, and outputs a voiceprint determination result as an output Hi signal. (B) CPU 115
Calculates the time between the time t _A at the time of receiving the Hi signal and the time t _B at the time of receiving the Low signal, and defines the time as t _Cn (n is a natural number). If this is equal to or longer than the time set by the user (set time) t _C , then the CPU 115 causes the CPU 115 to reproduce the first recording / reproducing unit 111 and the second recording / reproducing unit 11.
2 is transmitted. As is clear from FIG. 14, in this case, only t _C3 is larger than time t _C. (C) is a recording operation of the first recording / reproducing unit 111,
After selecting what to judge as the judgment processing unit and the specific information, the recording starts with the start of the recording (reservation).
(D) and (e), as described above, operate when the CPU 115 receives the reproduction start signal for the first recording / reproducing unit 111 and the recording start signal (Hi signal) for the second recording / reproducing unit 112, respectively. Will be In the third embodiment, the recording frequency is smaller than the recording frequency in the first embodiment, and one (from the start to the stop of recording) is longer than the set time. For this reason, according to the third embodiment, since a portion having a short recording time such as recording for only a few seconds (seconds) is not recorded, the capacity of the recording / reproducing unit, for example, the HDD or DVD-RAM can be saved. . The user can directly operate the set time from the operation unit 114 as needed.

According to the first, second, and third embodiments, by using techniques such as voiceprint recognition, image recognition, and melody recognition, image information or voice information of a desired person or song can be selected. It becomes possible to record or reproduce the data. Also, image information and audio information before and after the desired portion can be recorded or reproduced. Further, since the position (address) where the desired image information or audio information is recorded can be stored, the desired portion can be located and reproduced in a short time. In addition, recording can be performed only when a characteristic portion using voiceprint recognition, image recognition, and melody recognition continues for a certain period of time or more, thereby preventing malfunction due to noise and saving recording media.
