  The ROM 144 has a program storage area made up of, for example, a non-volatile memory. Specifically, the ROM 144 has a setting program 144a, a first recording program 144b, a conversion program 144c, a second recording program 144d, a reproduction program 144e, A selection program 144g, a recognition program 144f, a deletion program 144h, a recording control program 144i, and the like are stored.

The setting program 144a is a program for causing the CPU 141 to realize a function for setting the recording start time and recording end time of broadcast program data, for example.
Specifically, when detecting a remote control signal based on the operation of the recording reservation key 21b in the key operation unit 21 of the remote controller 2, the CPU 141 displays the menu screen illustrated in FIG. 4 on the display unit 200a. On this menu screen, the user inputs reservation date / time information (date, day of the week, recording start time, recording end time), information on the broadcast program to be recorded, such as a channel. The CPU 141 sets the recording reservation of the broadcast program by storing in the reservation table 1432a the reservation date / time information, the channel, and the like input on the menu screen.
In the following description, the set recording start time in the recording reservation set by executing the setting program 144a is referred to as “set recording start time”, and the set recording end time is referred to as “set recording end time”. I will do it.
The CPU 141 functions as a setting unit by executing the setting program 144a.

The first recording program 144b is, for example, a program for causing the CPU 141 to realize a function of recording broadcast program data received by the tuner 6 with high image quality (first image quality). The first recording program 144b is a first control and / or setting program 144a that causes the CPU 141 to start recording broadcast program data a predetermined time before the recording start time set by the execution of the setting program 144a. The second control for ending the recording of the broadcast program data is executed after a predetermined time from the recording end time set by the execution.
Specifically, the CPU 141 records broadcast program data on the magnetic disk 111 with high image quality in the execution of the first recording program 144b. Further, when the recording reservation of the broadcast program is set by executing the setting program 144a, the CPU 141 additionally records a predetermined time before and after the broadcast program reserved for recording. For example, recording of broadcast program data is started a predetermined time before the set recording start time (for example, 30 minutes), and broadcast program is recorded a predetermined time (for example, 1 hour) after the set recording end time. End data recording.
The extra recording time can be arbitrarily set by the user in advance on the menu screen. Further, it can be set to perform either one of the process of starting recording a predetermined time before the set recording start time and the process of ending the recording after a predetermined time after the set recording end time.
The CPU 141 functions as a first recording unit together with the magnetic disk 111 and the disk drive unit 11 by executing the first recording program 144b.

Here, a specific example of recording broadcast program data by executing the first recording program 144b will be described with reference to FIG.
As shown in FIG. 5, for example, when the set recording start time of the recording reservation is 13:00 and the set recording end time is 15:00, the CPU 141 records the broadcast program data at the set recording start time. It starts at 12:30 30 minutes before and ends at 16:00, one hour after the set recording end time. That is, actually, broadcast program data from 12:30 to 16:00 including extra data before the set recording start time and after the set recording end time is recorded on the magnetic disk 111.
When recording on the magnetic disk 111, the CPU 141 broadcast data from the set broadcast start time to the set broadcast end time (that is, broadcast program data from 13:00 to 15:00) and the set recording start time. The extra recorded data after the previous / set recording end time (that is, broadcast program data from 12:30 to 13:00 and broadcast program data from 15:00 to 16:00) are recorded separately.

The conversion program 144c has a function of converting, for example, the broadcast program data recorded by the execution of the first recording program 144b into the standard image quality (second image quality) lower than the high image quality (first image quality) in the CPU 141. It is a program for realizing. The conversion program 144c is executed together with the second recording program 144d described later during the reproduction of the broadcast program data converted to the standard image quality (second image quality) by the execution of the reproduction program 144e described later.
Specifically, when the CPU 141 detects a remote control signal based on the operation of the reproduction key 21 c in the key operation unit 21 of the remote controller 2, the CPU 141 selects desired broadcast program data from the broadcast program data recorded on the magnetic disk 111. Menu screen is displayed on the display unit 200a. When the user selects broadcast program data recorded with high image quality by executing the first recording program 144b on this menu screen, the CPU 141 causes the disk drive unit 11 to select the selected high-quality broadcast program data. Is output to the buffer memory 10a of the data processor 10 and output to the decoder unit 12 for decoding. Further, the CPU 141 causes the encoder unit 9 to output the data decoded by the decoder unit 12 and causes the encoder unit 9 to recompress the data in a standard image quality format.
The CPU 141 functions as a conversion unit together with the encoder unit 9 by executing the conversion program 144c.

The second recording program 144d is, for example, a program for causing the CPU 141 to realize a function of recording broadcast program data converted to standard image quality (second image quality) by executing the conversion program 144c. The second recording program 144d is executed together with the conversion program 144c described above during the reproduction of the broadcast program data converted to the standard image quality (second image quality) by the execution of the reproduction program 144e described later.
Specifically, when the broadcast program data recorded in the high quality format on the magnetic disk 111 is recompressed in the standard quality format in the execution of the conversion program 144c, the CPU 141 converts the broadcast program data into the data The data is output to the disk drive unit 11 via the processor 10 and is recorded on the magnetic disk 111 in association with high-quality broadcast program data based on the same stored broadcast program data.
The CPU 141 functions as a second recording unit together with the magnetic disk 111 and the disk drive unit 11 by executing the second recording program 144d.

Here, the data structure of the magnetic disk 111 will be described with reference to FIG.
The magnetic disk 111 includes servo data areas and write data areas that are radially embedded in the radial direction of the magnetic disk 111. The servo data area is composed of a track number, a sector number, and burst data. Upon receiving a write command and a write destination address, the disk drive unit 11 specifies the current position of the magnetic head 112 based on the servo data. Then, the magnetic head 112 is moved to the target address to write data. The write data area stores a preamble, a sync mark (sync), user data (user data), an error correction code (ECC), a postamble (postamble), and the like.
In the user data area, the area for storing high-quality broadcast program data by execution of the first recording program 144b and the high-quality broadcast program data by execution of the second recording program 144d are recompressed. And an area for storing the standard-definition broadcast program data generated in such a manner that the high-definition broadcast program data and the standard-definition broadcast program data based on the same broadcast program data are associated with each other. Stored. Recording high-quality broadcast program data requires a larger recording capacity than standard-quality broadcast program data. On the other hand, the standard-definition broadcast program data is inferior to the high-quality broadcast program data in image quality, but requires a smaller recording capacity than the high-quality broadcast program data.
These broadcast program data are recorded with distinction between data from the set recording start time to the set recording end time and extra recorded data before the set recording start time / after the set recording end time.
The magnetic disk 111 forms part of the first recording means and part of the second recording means by recording high-quality broadcast program data and standard-quality broadcast program data.

The reproduction program 144e is a program for causing the CPU 141 to realize a function of reproducing broadcast program data converted to standard image quality (second image quality) by executing the conversion program 144c, for example.
Specifically, when the broadcast program data recorded in the high-quality format on the magnetic disk 111 is recompressed in the standard-quality format in the execution of the conversion program 144c, the CPU 141 converts the broadcast program data into the above-described broadcast program data. The second recording program 144 d is recorded on the magnetic disk 111, while being output to the decoder unit 12 for decoding and reproduction processing to be output to the television receiver 200 connected to the apparatus body 1. Then, in the television receiver 200, an image based on the broadcast program data is displayed on the display unit 200a, and sound is output from the audio output unit 200b.
In this playback process, the CPU 141 allows the user to distinguish whether the video displayed on the display unit 200a is data from the set recording start time to the set broadcast end time, or is extra recorded data. As described above, the broadcast program data from the set recording start time to the set recording end time and the extra recorded portion of the broadcast program data are reproduced in different modes. For example, as shown in FIG. 7, the CPU 141 performs OSD display such as “extra recorded video” together with the extra recorded video when reproducing the video of the extra recorded portion. Further, for example, a method of reproducing by reducing the luminance of the video of the extra recorded portion or a method of muting the audio when reproducing the extra recorded portion may be adopted.
The CPU 141 functions as a playback unit together with the disk drive unit 11 by executing the playback program 144e.

The selection program 144g has high-quality (first image quality) broadcast program data recorded by the execution of the first recording program 144b and standard image quality (second image quality) recorded by the execution of the second recording program 144d. This is a program for realizing a function of allowing a user to select any broadcast program data out of the broadcast program data. The selection program 144g causes the user to select any broadcast program data by causing the user's voice information input by the voice input unit 23 to be recognized by executing the recognition program 144f.
Specifically, during execution of the reproduction program 144e described above, the user sees the video in the standard quality format displayed on the display unit 200a of the television receiver 200, and whether the standard quality recording is sufficient. Alternatively, it is determined whether standard image quality is not sufficient and high-quality recording is necessary. If it is determined that the recording of the standard image quality is sufficient, the voice information input key 21a of the key operation unit 21 of the remote controller 2 is pressed while speaking toward the microphone 231 (for example, “record with standard image quality”). Then, audio information indicating that recording is performed with standard image quality (or recording is not performed with high image quality) is input. If the user determines that the recording with the standard image quality is not sufficient, the user speaks toward the microphone 231 while pressing the voice information input key 21a (for example, “record with high image quality”). Input audio information to record (or not to record with standard image quality). The audio information input from the microphone 231 of the audio input unit 23 is modulated by the modulation unit 232 and transmitted to the apparatus main body 1 by the transmission unit 233.
The CPU 141 functions as a selection unit by executing the selection program 144g.

The recognition program 144f is a program for causing the CPU 141 to realize a function of recognizing audio information input by the audio input unit 23, for example.
Specifically, when the reception unit 3 receives the voice information transmitted from the voice input unit 23 of the remote controller 2, the CPU 141 demodulates the voice information in the voice information demodulation unit 4 and sends it to the voice recognition unit 5. Output. Then, the voice recognition unit 5 performs voice recognition processing on the input voice information.
The CPU 141 functions as a voice recognition unit together with the voice recognition unit 5 by executing the recognition program 144f.

The deletion program 144h is, for example, the high-quality (first image quality) broadcast program data or the second recording program 144d recorded by the execution of the first storage program on the CPU 141 based on the selection by the execution of the selection program 144g. Is a program for realizing a function of deleting broadcast program data of standard image quality (second image quality) recorded by executing the above.
Specifically, when the voice information input by the user in the voice input unit 23 is recognized by the voice recognition unit 5 by the execution of the recognition program 144f, the CPU 141 stores the information on the magnetic disk 111 based on the recognition result. One of the recorded high-quality broadcast program data and standard-quality broadcast program data is deleted.
For example, when the input audio information is recognized as “record with standard image quality”, the CPU 141 deletes the high-quality broadcast program data from the magnetic disk 111 and leaves the standard-quality broadcast program data. For example, when the input audio information is recognized as “recording with high image quality”, the CPU 141 deletes the standard-quality broadcast program data from the magnetic disk 111 and leaves the high-quality broadcast program data.
The CPU 141 functions as a deletion unit by executing the deletion program 144h.

  The recording control program 144i is recorded by executing the first recording program 144b and / or the second recording program 114d, for example, when the preset sound information is recognized by the CPU 141 by executing the recognition program 144f. The broadcast program data before the recording start time set by execution of the setting program 144a and / or the broadcast program data after the recording end time set by execution of the setting program 144a are deleted from the one broadcast program data. It is a program for realizing the function.

Specifically, the user sees the standard-definition broadcast program data reproduced on the television receiver 200 by the execution of the reproduction program 144e, and shifts between the actual broadcast start time and the set recording start time. Judge whether there is.
If it is determined that the actual broadcast start time matches the set recording start time, the microphone 231 of the audio input unit 23 is pressed while the audio information input key 21a of the key operation unit 21 of the remote controller 2 is pressed. Voice information indicating that the broadcast program data before the set recording start time set by the execution of the setting program 144a is to be deleted is input. Then, the CPU 141 deletes the extra recorded data before the set recording start time from the high-quality broadcast program data recorded on the magnetic disk 111. When standard-definition broadcast program data is recorded on the magnetic disk 111, data before the set recording start time is deleted.
On the other hand, if the user determines that the actual broadcast start time does not coincide with the set recording start time, the key operation unit 21 of the remote controller 2 at the actual start time of the broadcast recording that has been reserved and recorded in the reproduction process. While pressing the voice information input key 21a, the voice is input to the microphone 231 of the voice input unit 23 (for example, “recording start”), and voice information indicating that the time is the actual broadcast start time is input. Then, the CPU 141 deletes data before the time when the audio information is input from the high-quality broadcast program data and / or standard-quality broadcast program data recorded on the magnetic disk 111.

Whether the user sees the broadcast program data with the standard image quality reproduced on the television receiver 200 by executing the reproduction program 144e, and whether there is a difference between the actual broadcast end time and the set recording end time. Judge whether or not.
If it is determined that the actual broadcast end time coincides with the set recording end time, the microphone 231 of the audio input unit 23 is pressed while the audio information input key 21a of the key operation unit 21 of the remote controller 2 is pressed. Voice information indicating that the broadcast program data after the set recording end time set by execution of the setting program 144a is to be deleted is input. Then, the CPU 141 deletes the extra recorded data after the set recording start time from the standard-definition broadcast program data recorded on the magnetic disk 111. If standard-definition broadcast program data is recorded on the magnetic disk 111, the data after the set recording end time is deleted.
On the other hand, when the user determines that the actual broadcast end time does not coincide with the set recording end time, the key operation unit 21 of the remote controller 2 at the actual end time of the broadcast program that has been reserved and recorded in the reproduction process. While pressing the voice information input key 21a, the voice is input to the microphone 231 of the voice input unit 23 (for example, “recording end”), and voice information indicating that the actual broadcast end time is input. Then, the CPU 141 deletes data after the point in time when the audio information is input from the high-quality broadcast program data and / or standard-quality broadcast program data recorded on the magnetic disk 111.
The CPU 141 functions as a recording control unit by executing the recording control program 144i.

In step S17, it is determined whether or not the recognized audio information is audio information for recording with standard image quality (eg, “record with standard image quality”). If the CPU 141 determines in step S17 that the recognized audio information is audio information for recording with standard image quality (step S17; Yes), the high-quality broadcast program data is read from the magnetic disk 111 in step S18. Delete this, leave only standard-definition broadcast program data, and end the process.
On the other hand, if the CPU 141 determines in step S17 that the recognized audio information is not audio information for recording with standard image quality (step S17; No), the recognized audio information is recorded with high image quality in step S19. It is determined whether or not the audio information (for example, “record with high image quality”). If the CPU 141 determines in step S19 that the recognized audio information is not audio information for recording with high image quality (step S19; No), the process ends. On the other hand, if it is determined that the recognized audio information is unrelated audio information to be recorded with high image quality (step S19; Yes), in step S20, the standard-definition broadcast program data is deleted from the magnetic disk 111, and high Only the broadcast program data with the image quality is left, and this process is terminated.

  Next, broadcast program data editing processing by executing the recording control program 144i will be described with reference to the flowchart of FIG. This process is performed during the reproduction of broadcast program data by the execution of the reproduction program 144e.

First, in step S <b> 31, the CPU 141 determines whether or not the audio information transmitted from the audio input unit 23 has been input to the apparatus main body 1. If the CPU 141 determines in step S31 that voice information has been input to the apparatus main body 1 (step S31; Yes), in step S32, the CPU 141 causes the voice recognition unit 5 to perform voice recognition processing on the input voice information. In step S33, it is determined whether or not the recognized audio information is audio information (for example, “recording start”) indicating that the time is the actual broadcast start time. When the CPU 141 determines that the recognized sound information is sound information indicating that the time is the actual broadcast start time (step S33; Yes), the sound information is input from the magnetic disk 111 in step S34. The broadcast program data before the point of time is deleted, and the process proceeds to step S37. On the other hand, if the CPU 141 determines in step S33 that the recognized voice information is not voice information indicating that the time is the actual broadcast start time (step S33; No), the process proceeds to step S35.
In step S <b> 35, the CPU 141 determines whether or not the recognized audio information is audio information indicating that there is no difference between the set recording start time and the actual broadcast start time (for example, “no problem at the recording start time”). to decide. If the CPU 141 determines in step S35 that the recognized audio information is audio information indicating that there is no difference between the set recording start time and the actual broadcast start time (step S35; Yes), the magnetic disk 111 is determined in step S36. Then, the broadcast program data before the set recording start time is deleted, and the process proceeds to step S37. On the other hand, when the CPU 141 determines that the recognized audio information is not audio information indicating that there is no difference between the set recording start time and the actual broadcast start time (step S35; No), the CPU 141 proceeds to step S37.

In step S <b> 37, the CPU 141 determines whether or not the recognized audio information is audio information indicating that the time is the actual broadcast end time (for example, “recording end”). When the CPU 141 determines that the recognized audio information is audio information indicating that the time is the actual broadcast end time (step S37; Yes), the audio information is input from the magnetic disk 111 in step S38. Broadcast program data after the point of time is deleted, and this process is terminated.
