Description

  The present invention relates to a disk recording apparatus, and more particularly to a disk recording apparatus having a dubbing function for transferring data recorded on a first disk recording medium to a second disk recording medium for re-recording.

  In recent years, since disk recording / reproducing apparatuses are widely used, broadcast program data can be recorded on a disk recording medium such as a DVD (Digital Versatile Disc), stored, reproduced, and enjoyed. A DVD or HDD (Hard Disk Drive) or the like, which is a recording medium of a disk recording / reproducing apparatus, has a much larger recording capacity than a conventional magnetic tape, and is suitable for recording a large amount of program data.

  When there is personally favorite program data, there is a demand to repeatedly dubb only that program data on a DVD and enjoy it. By repeatedly recording the same program data on the DVD in this way, once the DVD is set to the playback mode, the desired program data is played and output endlessly, and the user can perform any operation. There is convenience that you can enjoy your favorite program data repeatedly.

As a function for repeatedly dubbing the same data, for example, conventionally, a technique described in Patent Document 1 has been provided. In this document, a technique is provided in which two cassette tape recorders are provided, and data in a selected area of the recording tape is repeatedly recorded from one cassette tape recorder to the other cassette tape recorder.
Japanese Patent Laid-Open No. 05-101610

  In Patent Document 1 described above, the target recording medium for dubbing is a cassette tape recorder and not a disk medium such as a DVD. In addition, the cassette tape recorder requires rewinding and fast-forwarding operations during repeated dubbing, so that there is a disadvantage that the operability is not superior compared to a disk.

  As described above, the function of repeatedly dubbing selected area data from the cassette tape recorder to the cassette tape recorder has been provided in the past, but the function of repeatedly dubbing only predetermined data using the target recording medium as a disk. Was not offered.

  SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a disc recording apparatus capable of repeatedly dubbing desired data recorded on a disc to the other disc.

  A disk recording apparatus according to an aspect of the present invention includes a first disk on which data is recorded, a second disk, and a portion that is re-recorded on a second disk from data recorded on the first disk. Target specifying means for specifying the target data that is the target data, target data reading means for reading the target data specified by the target specifying means from the first disk, and target data read by the target data reading means And a repetitive recording means for repetitively recording on the second disk.

  According to the present invention, if target data is designated through the target designating means, the target data designated by the target designating means is read from the first disc and repeatedly recorded on the second disc. Therefore, the user can automatically and repeatedly dub the target data to the second disc only by specifying the desired target data.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 shows the configuration of a disk recording / reproducing apparatus according to an embodiment of the present invention. Referring to FIG. 1, a disc recording / reproducing apparatus is a TV antenna 1 that receives TV (Television) broadcasts, and a tuner that performs a tuning operation for extracting a broadcast signal corresponding to a desired channel from a broadcast signal received by TV antenna 1. 2. A digital conversion unit 3 that converts a broadcast signal extracted by the tuner 2 into a digital signal in accordance with a predetermined encoding method, an encoder that encodes the digital signal converted and output by the digital conversion unit 3 and outputs the digital signal as digital data 4. Digital data output from the encoder 4 is recorded, and the HDD 5 (not shown) that can hold the recorded contents even when the supply power is cut off. Write / read to control the writing and reading of digital data to and from The output control unit 6, the digital data read from the HD 5 by the HDD 5 or the digital data read from the DVD 16 are input and decoded, and the digital signal output from the decoder 7 and decoder 7 that outputs the digital signal is input and analog An analog conversion unit 8 that converts the signal into a signal and outputs it, and an output unit 9 such as a TV receiver for inputting the analog signal output from the analog conversion unit 8 and outputting it as video, audio, or the like.

  Further, the disk recording / reproducing apparatus of FIG. 1 includes a CPU (Central Processing Unit) 10 for controlling the tuning operation of the tuner 2, the encoding operation of the encoder 4, the decoding operation of the decoder 7, and the operation of the writing / reading control unit 6. In addition, storage units 11 and 12 including a RAM (Random Access Memory) and a ROM (Read Only Memory) for storing various types of information including information (programs, data, etc.) for the CPU 10 to control them, and externally A command / instruction by an infrared signal is received from a remote controller (abbreviated as a remote controller) 14 provided, converted into data, input to the CPU 10, an OSD (On Screen Display) circuit 15, a DVD 16, and clocked. A timer 17 and an EPG (Electric Program Guide) extraction unit 18 are provided.

  Here, the DVD 16 may be a DVD-R, a DVD-RAM (also referred to as a DVD-RW (Digital Versatile Disc ReWritable)), or the like.

  The OSD circuit 15 creates drawing data based on the digital information given from the CPU 10 and outputs it to the analog conversion unit 8. When the drawing data is input, the analog conversion unit 8 converts only the drawing data into analog, or converts the drawing data and data read from the HDD 5 or the DVD 16 and supplied through the decoder 7 into an analog output unit. 9, an image based on the given data is displayed on the output unit 9.

  When the command from the remote controller 14 is not input, the input unit 13 may include various switches and buttons operated by the user for inputting commands / instructions from the outside.

  The remote controller 14 includes a numeric keypad 140 for specifying a channel operated by the user from the outside, a start key 141, an end key 142, a cursor key 143, and a mode switching key 144. The cursor key 143 includes a plurality of types of keys for moving a pointer such as a cursor displayed on the output unit 9 in the up, down, left, and right directions. The start key 141 and the end key 142 are operated to specify data to be dubbed.

  The EPG extraction unit 18 extracts EPG information of program data transmitted together with a broadcast signal from digital information input via the antenna 1, the tuner 2, and the digital conversion unit 3, and gives the extracted EPG information to the CPU 10. .

  Note that writing (recording) / reading (reproduction) of information on the HD by the HDD 5 and writing (recording) / reading (reproduction) of information on the DVD 16 are performed under the control of the CPU 10. 6 is performed. Here, the read / write control unit 6 is provided in common for the HDD 5 and the DVD 16, but the write / read control unit 6 may be provided individually.

  The repeated dubbing operation will be described with reference to the flowchart of FIG.

  When the user desires to repeatedly dubb the desired data recorded in the HDD 5 onto the DVD 16, the user operates the mode switching key 144 of the remote controller 14 to set the repeated dubbing function. The CPU 10 determines whether or not the repeated dubbing function has been set by inputting a signal from the remote controller 14 via the input unit 13 (step S (hereinafter simply referred to as S) 3).

  If the CPU 10 determines that the repeated dubbing function is not set based on the input signal (NO in S3), the CPU 10 proceeds to another designated process.

  On the other hand, if it is determined that the repeated dubbing function has been set (YES in S3), then the dubbing target data designated by the user is specified (step S5). Details of the target data specifying process will be described later.

  Next, for the repeated dubbing of the target data, the CPU 10 inputs the number of repeated dubbing set by the user by operating the remote controller 14 and sets it in the number of times data RP (S7). Thereafter, a control variable N for controlling the number of times of dubbing is initialized to 1 (S9).

  Next, the CPU 10 expands the dubbing target data specified by the target data specifying process and stored in the storage unit 11 in the storage unit 11 and converts it into a format suitable for the DVD 16 (S11).

  The data converted into the format is read from the storage unit 11 and given to the encoder 4, where it is encoded, and the data after the encoding is given to the DVD 16. At this time, the write / read controller 6 is controlled by the CPU 10 and operates to record the given target data on the DVD 16 (S13). After recording, the CPU 10 increments the value of the control variable N by 1 because dubbing of the target data is completed once (S15).

  Thereafter, the CPU 10 compares the value of the control variable N with the data RP of the number of repetitions initially set by the user, and determines whether N> RP is satisfied (S17). If it is established (YES in S17), the target data is dubbed to the DVD 16 for the designated number of repetitions, and thus the series of dubbing processes ends. If not (NO in S17), the process of S13 Returning to step S13, the processes in and after step S13 are repeated. As a result, the target data whose format has been converted in the storage unit 11 is read again from the storage unit 11 and recorded on the DVD 16 (the control variable N is also incremented by 1). This recording operation is repeated until it is determined in S17 that the condition (N> RP) is satisfied. When the condition is satisfied, the DVD 16 is in a state where RP pieces of the same target data are recorded.

  As described above, the user can read only desired target data out of the recorded data in the HDD 5 and repeat the re-recording (dubbing) of the read target data for the number of repetitions designated in the DVD 16.

  Here, the dubbing target data designation (S5) process of FIG. 2 will be described.

  FIG. 3 shows an example of a dubbing target data designation procedure. First, the CPU 10 reads the title of the program data recorded in the HDD 5 and displays a list of program titles on the output unit 9 via the OSD circuit 15. The user looks at the displayed title list and designates a desired program title, that is, a program title to be dubbing target data by operating the cursor key 143 of the remote controller 14 (S53).

  The CPU 10 inputs a program title designation signal from the remote controller 14, reads program data designated based on the input signal, that is, program data to be dubbed from the HDD 5, and stores it in the storage unit 11 (S55). Thus, the dubbing target data specifying process is completed.

  In FIG. 3, the target data is one piece of program data. However, as shown in FIG. 4, it may be desired partial data in certain program data. For example, in S61 and S63 of FIG. 4, the CPU 10 inputs the program title designated by the user in the same procedure as the processing of S51 and S53 described above.

  When the CPU 10 inputs a designated program title, the program data of the program title is read from the HDD 5 and the read program data is reproduced and output (displayed) on the output unit 9 via the recorder 7 and the analog conversion unit 8 ( S65).

  The user operates the remote controller 14 to identify the partial data to be dubbed while looking at the reproduction screen of the designated program data. Specifically, when the reproduction of the desired partial data is started on the screen of the output unit 9, the start key 141 is pressed (YES in S67). An instruction to press the start key 141 is given to the CPU 10. While the start key 141 is not pressed (NO in S67), the reproduction screen for the designated program data is continuously output.

  Once the start key 141 is pressed (YES in S67), the CPU 10 inputs the data read from the HDD 5 and given to the output unit 9 at that time via the decoder 7 in parallel. (S69). Thereafter, it is determined whether or not the user has operated the remote controller 14 to operate the end key 142 that indicates the end of the target data (S71). While the end key 142 is not operated (NO in S71), the reproduction operation similar to the processing of S65 is performed (S68), and the data read from the HDD 5 and displayed on the output unit 9 is stored in parallel in the storage unit 11 (S69).

  On the other hand, when the end key 142 is pressed (YES in S71), the instruction signal is given to the CPU 10, so that the CPU 10 detects that the end key 142 is pressed based on the instruction signal (YES in S71). ). In response to the detection, the CPU 10 stops reading data from the HDD 5, so that the data storage operation in the storage unit 11 is stopped (S73), and the reproduction output to the output unit 9 is also stopped.

  Thus, the desired partial data of the program data of the designated title can be stored in the storage unit 11 as dubbing target data.

  In FIG. 4, as desired partial data of program data, for example, favorite commercial data, favorite artist's appearance scene data, and the like can be designated.

  A part of the processing procedure of FIG. 4 may be changed as follows. After the start key 141 is operated, it is assumed that the user operates the start key 141 again without operating the end key 142. Thus, when the user operates the start key 141 again, the CPU 10 discards (erases) the data stored in the storage unit 11 from the previous operation of the start key 141, and again starts the start key 141. The storage of the reproduction data at the time when is operated to the storage unit 11 is started. By processing in this way, even if the user mistakenly specifies the start timing of the partial data to be dubbed, the user can simply operate the start key 141 at the time when the correct timing data is obtained, and the desired portion Data can be stored in the storage unit 11 as dubbing target data.

  Conventionally, it has been necessary for the user to repeat the dubbing operation by designating the title for the number of times of dubbing. However, in this embodiment, once the dubbing target data called the program title and the dubbing count are designated once, Since dubbing is automatically repeated, user operation is simplified and operation mistakes can be prevented.

  Here, the period for dubbing the target data is specified by the number of repetitions RP. However, the period is not limited to the number of times data. For example, it is specified by the time period for dubbing or until the recordable area of the DVD 16 runs out. It is also possible.

  When the dubbing repetition is designated by the time period, the CPU 10 determines whether or not the dubbing has been repeated for the designated time period from the start of the dubbing based on the time data counted by the timer 17 and given to the CPU 10. Can do. If it is specified that the recordable area of the DVD 16 is exhausted, the CPU 10 reads free space data stored in a predetermined area of the DVD 16 at the start of dubbing, and at the start of dubbing for each subsequent repeated dubbing ( This can be dealt with by determining whether or not the condition of dubbing target data capacity> (free capacity−total capacity of data dubbed so far) is satisfied and repeating dubbing until the condition is satisfied.

  Here, the dubbing is started by the user operating the remote controller 14 here, but may be automatically performed according to the dubbing reservation information. That is, a dubbing reservation table 61 in which data indicating the dubbing start time and data RP of the number of dubbing repetitions is set in the storage unit 12, and the CPU 10 executes a dubbing operation according to the contents of the dubbing reservation table 61. That is, when the time measured by the timer 17 indicates the dubbing start time of the dubbing reservation table 61, the dubbing target data stored in advance in the storage unit 11 is repeatedly dubbed the number of times indicated by the data RP.

  In the present embodiment, transfer from the HDD 5 to the DVD 16 has been described, but a route of transferring from the DVD 16 to the HD 5 may be used.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
