In this configuration, the character string may be deleted for all the video files recorded in the first recording unit, or the selected video file may be deleted from the video files recorded in the first recording unit. May be.

  According to the recording apparatus of the present invention, since the registered character string is deleted from the title of the video file, usability can be improved in managing the title.

  FIG. 1 is a block diagram showing the configuration of the main part of a DVD recorder 1 according to an embodiment of the present invention. The DVD recorder 1 of this embodiment records a video signal on a recording medium such as a DVD and reproduces a video file recorded on the recording medium.

  The DVD 10 that can be mounted on the DVD recorder 1 of this embodiment is a rewritable DVD-RW or the like, or a recordable optical disc DVD-R, but is not limited to the DVD of this embodiment, and other optical discs. Even when recording, this apparatus can be applied.

  A video signal and an audio signal are input to the input unit 2. The video signal and audio signal are input from, for example, an external video signal output device. The input unit 2 includes a receiving unit that receives a broadcast signal. Video signals, audio signals, and text information are extracted from digital broadcast signals received by an antenna (not shown).

  The receiving unit extracts an MPEG video signal, audio signal, and character information from the transport stream (TS) received from the antenna. Specifically, the receiving unit includes a tuner pack, a terrestrial digital module, a tuner control unit, a demodulation circuit, and an error correction circuit. The tuner pack includes an IF filter, an IF amplifier, and the like. An IF filter (intermediate frequency) passes a signal of a predetermined physical channel instructed by the tuner control unit. The IF amplifier amplifies this signal. Thus, the tuner pack extracts the broadcast signal of the channel designated by the tuner control unit. Further, the demodulation circuit demodulates the input broadcast signal into digital data TS (transport stream) by OFDM (Orthogonal Frequency Division Multiplexing), and outputs it to the error correction circuit. The error correction circuit corrects error information of the input TS (transport stream) and outputs it to the terrestrial digital module. The terrestrial digital module includes a multiplexer and a buffer memory. A plurality of virtual channel programs are multiplexed and transmitted in the TS. The demultiplexer extracts a packet of one channel among these virtual channels, and stores the data stored in the extracted packet in the buffer memory.

  The encoding unit 3 converts the analog format video signal and audio signal input by the input unit 2 into digital signals and encodes them. The encoding unit 3 outputs the encoded data to the disk drive 4. However, since the video signal extracted from the TS is already in the MPEG format, when it is recorded on the hard disk, it may not be encoded again in this format.

  The receiving unit of the input unit 2 may be an analog broadcast receiving unit. In this case, the receiving unit includes a filter for extracting an intermediate frequency and an intermediate frequency amplifying unit for amplifying the intermediate frequency band. Further, instead of the encoding unit 3, a video processing unit that extracts a video signal, a color signal reproduction unit, and a synchronization detection circuit are provided. The video processing unit includes a display data generation unit, a synchronization detection circuit, and a frame memory. The color signal reproduction unit extracts a color signal from the color video signal and generates RGB three primary color signals. The synchronization detection circuit extracts a horizontal synchronization signal and a vertical synchronization signal from the color video signal. The display data generation unit A / D converts the three primary color signals, and stores them in the frame memory in the video processing unit 33 based on the horizontal synchronization signal and the vertical synchronization signal. Thereby, a video signal is output.

  The recording / reading unit 4 includes an optical disk drive 41, which is a kind of recording medium, a hard disk 42 (abbreviated as HD42), and a hard disk drive 43 (abbreviated as HDD 43). The optical disk drive 4 performs a pickup head (not shown) that irradiates the DVD 10 with laser light and detects the reflected light, and focus servo control and tracking servo control that control the irradiation position of the laser light irradiated on the DVD 10. It has a servo control unit (not shown) to perform. With these configurations, the optical disk drive 41 reads and records the DVD 10. The HD 42 is one type of recording medium. The HDD 43 records on the HD 42 and reads the recorded data.

  Note that the recording medium of the present embodiment only needs to be able to record video signals and audio signals, and includes not only optical disks but also portable memories such as flash memories, as well as those used for installation.

  With such a configuration, the recording / reading unit 4 records the video signal and the audio signal encoded by the encoding unit 3 on the DVD 10 or the HD 42. Hereinafter, recording of a video signal and an audio signal on a recording medium is referred to as recording.

  The signal processing unit 5 includes a demodulation unit, a decoder, and an OSD synthesis unit. The demodulator performs 8/16 demodulation or the like on the RF signal read by the disk drive 4, performs error correction, and extracts video data and audio data. The decoder decodes video data and audio data.

  The OSD synthesis unit synthesizes OSD (On-Screen Display) such as characters and characters of the OSD synthesis unit 5 based on the command issued by the control unit 9. When a video signal is output from the decoder, the video signal and the OSD are combined and output to the output unit 6. In some cases, the OSD synthesis unit may prohibit the output of the video signal and output only the OSD.

  The OSD synthesis unit stores various image data therein. For example, characters and graphics for displaying various character strings, user interface images displayed in the initial setting process 93, frame images of the electronic program guide (EPG), and frame images displayed in the title correction process 95 (FIG. 4) is stored. The OSD is output by combining these frame images with characters and graphics.

  The output unit 6 includes a D / A converter and the like, and D / A converts the video signal and audio signal processed by the signal processing unit 5. The output unit 6 synchronizes the D / A converted video signal and audio signal and outputs them to the display 11 and the speaker 12.

  The operation unit 8 receives an input for instructing an operation on the apparatus main body. The operation unit 8 includes a remote control reception unit that receives a plurality of operation keys and a control code for the apparatus main body transmitted from the remote control device 81. The operation unit 8 receives an input corresponding to an operation key operated by the user, and transmits a code corresponding to the key and a control code received by the remote control reception unit to the control unit 9. For example, the operation unit 8 receives a recording instruction or a recording reservation.

  The control unit 9 is constituted by a microcomputer and includes a CPU, a RAM, and a ROM for storing control data. Based on the input received by the operation unit 8, the control unit 9 controls the operations of the respective units 2 to 8 among the devices described above. The ROM of the control unit 9 stores a subroutine for executing a recording reservation process 91, a management process 93, and a recording process 92 for making a recording reservation in advance. Further, the flash memory 99 is connected to the outside of the control unit 9 and records the state of the DVD recorder 1 and various initial setting information.

  In the recording reservation process 91, selection of a recording reservation item is accepted. The recording reservation process 91 is executed when a predetermined key operation is received in advance before the start of the broadcast program to be recorded. In the recording reservation process 91, the scheduled recording time T [H], the scheduled recording time, the channel number of the television to be recorded, the day of the week or the date, and the designation of the recording medium to be recorded are received from the user. Also, selection of a recording mode for designating image quality may be accepted.

  In the recording reservation process 91, the control unit 9 outputs a screen of an electronic program guide (EPG) based on the character data fetched from the receiving unit, and accepts a broadcast program for recording reservation. In the management process 93, a process for managing the recorded video file is performed.

  In the recording process 92, the control unit 9 controls the start and stop of the recording operation. In the recording process 92, the recording of the broadcast program is started based on the recording reservation data. In the initial setting process 93, changes in various settings are accepted and the settings are recorded in the flash memory 99. The initial setting process 93 includes a registration process 94. In the registration process 94, a predetermined character string is registered before the process of the title correction process 95. In the title correction process 95, the registered character string is deleted from the title (namely, file name) of the recorded video file, and the title is corrected. In the dubbing process 97, the video file recorded on the HD 42 is dubbed to the DVD 10.

  A display 101 and a speaker 102 are connected to the DVD recorder 1. The display device 101 displays a video based on the video signal output from the output unit 6. The speaker 102 amplifies the sound signal output from the output unit 6 and emits sound. For example, a liquid crystal monitor, a plasma monitor, an EL monitor, a cathode ray tube, a projector, or the like is used.

  Next, an electronic program guide (EPG) displayed during the recording reservation process 91 will be described using the screen display example 51 of FIG. In this example, an EPG in which times 511 and channels 512 are arranged in a matrix is displayed on the screen of the display 101. The name of each program is displayed at the intersection of the matrix. The name of the program is displayed as, for example, “Drama A GG Wide”, “Movie X With Wide Subtitles”, “Drama Y GG Wide Appearance Mr.xx, etc”. When a program is selected in this state, the program channel, start time, and end time are registered. Furthermore, when the user sets image quality settings and the like, a program to be recorded is reserved. When the start time registered here is reached, the control unit 9 executes the recording process 92 to start recording.

  However, the title of the video file recorded in this way includes many character strings that the user does not need or prefer. Therefore, the control unit 9 performs a title correction process 95 in accordance with a user's predetermined operation. In the following description, it is assumed that there are “GG”, “other”, “wide”, and “S” as examples of this character string.

  A registration process 94 for registering a character string with initial settings will be described with reference to FIG. The registration process 94 is included in the initial setting process 93. In the initial setting process 93, various settings for the DVD recorder 1 are accepted. For example, “reception setting”, “screen setting”, “audio setting”, “recording setting”, and the like are received as in the screen 52. “Reception setting” accepts “channel setting” and the like. In “screen setting”, settings of the aspect ratio, luminance, and contrast of the screen are accepted. In “audio settings”, settings such as stereo and sub-audio are accepted. The highlight display 521 moves up and down by a cursor key (not shown) of the operation unit 8. The portion where the highlight display 521 is displayed is an item selected on the screen.

  If a determination button (not shown) of the operation unit 8 is pressed while the recording setting is selected, the recorder 1 switches to the screen 53 and outputs it. “Recording setting” accepts a default image quality bit rate setting when recording. In “recording setting”, “deletion setting of character string in title” is accepted. While this selection is being made (highlight display 531), when the enter button is pressed, the screen is switched to the screen 54 and displayed.

  On the screen 54, items of “automatic deletion setting on / off” and “registration of character string to be deleted” are displayed. When the user sets this to “ON” in the “automatic deletion setting”, a correction is made to automatically delete the character string in which the title of the file is registered after the recording is finished.

  When “Registration of character string to be deleted” is selected on the screen 54, a registration process 94 is performed. In this process, a character string considered unnecessary by the user in the title is received and registered in advance. In the registration process 94, a list of registered character strings is displayed and new registration is accepted.

  The “list of registered character strings” on the screen 54 includes factory default settings. Specifically, the manufacturer of the DVD recorder 1 investigates the EPG transmitted from the broadcasting station at the time of factory shipment. A character string that may be deleted by the user, such as “GG” or “subtitle”, can be registered. Note that this factory setting may be a setting that switches when the initial setting is reset to the default setting.

  In the new registration, the selection is accepted from the hiragana 541 and the character string is registered. It is also possible to accept selection of characters by arranging alphabets and katakana instead of hiragana. As another input method, as in a cellular phone, characters may be assigned to each numeric button, and when the numeric button is struck repeatedly, the alphabetic characters may be switched to accept the input. Moreover, even if it is not an alphabet, it may input in the same way, even if it is katakana or hiragana.

  Next, an example of a screen displayed when the title correction process 95 of FIG. 4 is performed is shown. In the title correction process 95, either batch deletion or selective deletion is performed. In the example of FIG. 4A, a file title group is displayed on the screen, and the highlight display 541 moves by selection. If the delete button is pressed when batch deletion is selected, all the character strings registered in the registration process 94 are deleted from all titles as shown in FIG. 4B. In addition, “deleted” or “finished” is displayed on the screen 55. In addition, a list of the results of correcting the title is displayed.

  Note that “all delete” does not correct “all titles” recorded on the recording medium (10 or 42), but extracts and displays a predetermined group, and the above corrections are made for all the titles. You may do.

  A screen 56 in FIG. 4C shows a case where the user has selected and deleted. In this case, the highlight display is moved to the file title list. Therefore, selection of a plurality of titles is accepted. When the user presses the enter button, only the selected title is corrected as shown in the screen 57 in FIG.

  Next, the flow of the title correction process 95 described above is shown using FIG. This process is executed by the control unit 9 when an operation for instructing this process is received from the user (ST1).

  In ST2, a predetermined file is selected, and the character string registered in the recording process 92 is selected. Searches whether the title of this file contains the selected character string. In ST3, if a character string is included as a result of searching in ST2, it is deleted. The above steps ST2 and ST3 are repeated for all registered character strings and all files. When all the repetitions are completed, a display of “finished” as shown in FIGS. 4B and 4D and a correction result are displayed.

  Next, an example in which the title correction process 95 is applied to the dubbing process 97 will be described using the flowchart of FIG. This process is executed when the dubbing process 97 is accepted according to the user's operation (ST11). In ST12, selection of a file to be dubbed is accepted. For example, as shown in FIG. 4C, selection is accepted from the title list. However, in this process, “select all” and “select file” are displayed instead of “collective deletion” and “selection deletion” as shown in FIG. When “Select file” is selected from “Select all” or “Select file”, the selection is accepted from the title list. When “Select all” is selected, all items displayed on the screen later are displayed. Dubbing files. In ST13, before dubbing, a title correction process 95 for correcting the title of the file recorded on the DVD 10 is performed.

  In ST14, the corrected title list is displayed to ask the user for confirmation. If consent is received, the process moves to ST15. In ST15, the corrected title is copied to the DVD 10. If the user selects not to accept, a title change may be received manually from the user. Thereafter, the control unit 9 ends the dubbing process 97.

  Note that the correction of ST13 and the manual title change may or may not be reflected in the base data in the HDD 43. In “all selection”, registration of a predetermined group may be received from the user, and “all selection” may be performed for all video files in the group.

  It supplements about the above embodiment.

  In the description of FIG. 1 described above, the blocks have been separated for each function. However, on implementation, any of these functions may be configured by a system IC in which a plurality of functions are integrated. One block may be divided into a plurality of blocks.

  The flash memory 99 may be attached to the microcomputer of the control unit 9. Even if the flash memory 99 is not directly connected to the control unit 9, it only needs to be accessible indirectly by the control unit 9.

Further, the decoder 4 may not be a specialized processing processor but may be decoded by software operating on a personal computer. OSD synthesis may also be performed on software. The control unit 9 may be a personal computer or a CPU of a game machine.

  The operation unit 8 may be an input device to a personal computer (keyboard, mouse, touch panel, game pad, etc.). When the above processing is performed by a personal computer, the operation unit 8 can be a mouse or other pointing device. The operation unit 8 may be any operation means such as a touch panel as long as it can instruct the control unit 9. The optical disk drive 41 and the HDD 43 do not need to have both except when performing the above dubbing, as long as they can be recorded and read on one or more recording media. However, in order to re-record the file whose title of the file recorded on the drive 41 is changed on the drive 41, it is necessary to use a disc that can be recorded a plurality of times or record it in another area on the disc.
