Description

  The present invention relates to a recording / reading apparatus that receives a broadcast television program and records it on a large-capacity medium such as an HD, and more particularly to a recording / reading apparatus that dubs a continuous program from a large-capacity medium to a removable medium such as a DVD.

  Conventionally, a television program broadcast by a television broadcast such as a terrestrial broadcast, a satellite broadcast, a cable broadcast, and an Internet television broadcast is recorded on a large-capacity medium such as an HD (Hard Disk), and the television program is recorded from a large-capacity medium to a DVD ( There was a recording / reading device that dubbed on removable media such as Digital Versatile Disk. As an example of such a recording / reading apparatus, a DVD recorder with HD will be described below.

  In recent years, DVD recorders with HD also have a continuous program recording reservation function that allows a user to easily make a recording reservation for a continuous program of a series that is broadcast a plurality of times. Examples of continuous programs include continuous dramas broadcast every week at the same time zone. The DVD recorder with HD having this function uses the program information transmitted from the broadcasting station together with the TV program to identify the TV program that the user is watching or recording, and schedules the next TV recording for the TV program. Easy to do. This program information is information indicating channel contents (including program name and broadcast time) several hours ahead, program contents, and the like. Based on the recording reservation, the DVD recorder with HD records, for example, a continuous drama broadcasted at the same time zone every week.

Many users dubb a plurality of continuous programs from HD to DVD for the purpose of long-term storage, etc., when a plurality of continuous programs are recorded in HD.
In Patent Document 1, a data recording apparatus is proposed.
JP 2006-114187 A

However, it is difficult for the user to know whether or not the capacity of one DVD is accumulated while the above-mentioned continuous programs are recorded in HD. Therefore, the user mistakes the timing of dubbing and frequently dubbs to DVD when the capacity of one DVD is not enough, or leaves the HD even though the capacity of one DVD has accumulated. It was.
Therefore, the conventional recording / reading apparatus has a problem that DVD management becomes difficult and HD storage management becomes difficult. Therefore, the conventional recording / reading apparatus is not user-friendly.

  The present invention is intended to solve such a conventional problem, and provides a recording / reading apparatus that improves the usability of a user by dubbing a large-capacity medium of a continuous program from a large-capacity medium to a removable medium at an appropriate timing. For the purpose.

  The recording / reading apparatus of the present invention has the following configuration in order to solve the above problems.

(1) receiving means for receiving a television broadcast signal of a television program broadcast on the selected channel and program information including the program name and broadcast time of the television program;
Recording processing for recording the television program on the first medium based on the television broadcast signal and the program information received by the receiving unit is performed under set setting conditions, and from the first medium to the television set. First recording means for reading a program;
A recording / reading apparatus comprising: a second recording unit configured to record the television program on a second medium detachable from the apparatus main body;
Control for controlling both the recording means, and for calculating the cumulative capacity of all series of the series programs broadcasted over a plurality of times among the television programs recorded on the first medium. With means,
The control means includes
After the recording of the continuous program is completed, a consumption capacity consumed in the recording of the next continuous program is estimated, and the sum of the estimated consumption capacity and the accumulated capacity exceeds the storage capacity of the second medium. Whether or not
If the total exceeds the storage capacity of the second medium, a dubbing process for recording the continuous program recorded on the first medium on the second medium is executed.

  In this configuration, the first medium is a large-capacity medium, for example, a hard disk. On the other hand, the second medium is a recordable removable medium, such as an optical disk or a semiconductor medium. The continuous program includes, for example, a continuous drama broadcasted at the same time zone every week. The program information is information indicating a broadcast schedule of a television program, and specifically indicates channel contents (including program name and broadcast time) several hours ahead, program contents, and the like. An electronic program guide (EPG) is created from this program information.

The recording / reading apparatus in this configuration has a continuous program recording reservation function that can easily make a recording reservation of a continuous program of a series broadcasted a plurality of times. A recording / reading apparatus having this function uses a program information transmitted from a broadcasting station together with a TV program to identify a TV program that the user is watching or recording, and easily schedules the next recording reservation for the TV program. To do. Then, based on the recording reservation, the recording / reading apparatus records, for example, continuous dramas broadcast every week at the same time zone. Thereby, the user records and accumulates a plurality of continuous programs on the first medium. Then, the user prepares one second medium for dubbing and sets it in the second recording means while recording a plurality of continuous programs on the first medium.
When the sum of the consumed capacity and the accumulated capacity exceeds the capacity of the second medium after the recording of the continuous program ends, the control means controls both the control means at this timing to Dubbing from the media to the second media is performed.
Therefore, dubbing of the continuous program from the first medium to the second medium can be performed at an appropriate timing when the capacity of one second medium is accumulated. Therefore, the user mistakes the dubbing timing and frequently dubbs to the second medium when the capacity for one second medium is not sufficiently accumulated, or the capacity for one second medium is accumulated. However, there is no need to leave the first media open. Therefore, management of the second medium is facilitated. Further, if the continuous program is dubbed to the second medium, the continuous program can be deleted from the first medium, so that storage management of the first medium is facilitated. Therefore, user convenience can be improved.

(2) The setting condition includes a recording image quality of the continuous program when recording on the first medium,
The control means estimates the consumed capacity based on the broadcast time of the next continuous program included in the program information and the currently set recording quality.

  In this configuration, the method for estimating the consumed capacity in (1) is specified.

(3) comprising a selection means for accepting selection of whether to execute the dubbing process before the dubbing process is executed;
The control means operates according to the selection result in the selection means.

According to this configuration, the user can select whether to perform dubbing according to his / her usage method. Therefore, user convenience can be further improved.
Further, since the control means operates in accordance with the selection result, the second medium can be set by the user at this timing. This eliminates the need to set the second medium in advance.

(4) comprising display means for displaying a message as to whether or not to execute the dubbing process before the dubbing process is executed;
The selection means accepts the selection in a state where the message is displayed on the display means.

  In this configuration, the user can see the message on the display unit and select whether to perform dubbing with the selection unit according to his / her usage method. Further, the user sees this message and sets the second medium when he / she wants to dubb.

(5) The control means instructs the first recording means to delete the continuous program recorded in the second medium and remaining in the first medium by the dubbing process.

Even if the continuous program dubbed to the second medium is left in the first medium, it is useless.
In this configuration, the continuous program remaining in the first medium is deleted.
Thereby, since the continuous program is automatically deleted, the user can effectively use the space of the first medium which is freed by deleting the continuous program. Accordingly, the storage management of the first medium is further facilitated, and the usability for the user can be further improved.

(6) The first medium is a hard disk,
The second medium is an optical disk.

  In this configuration, the optical disk is, for example, a CD, a DVD including an HDDVD, or a Blu-ray disk.

(7) When the dubbing process is completed, the control unit instructs the second recording unit to perform a finalizing process on the optical disc that physically and logically approaches the ROM type optical disc.

If the total exceeds the storage capacity of the optical disc, the user cannot record the next and subsequent series of programs on the optical disc. Further, if data other than the dubbed continuous program is recorded in the remaining area of the optical disc, the recorded content of the optical disc becomes complicated and the management of the optical disc becomes difficult.
In this configuration, finalization processing is forcibly performed on the optical disc. In the finalizing process, information relating to the data recording range and recording state is created on the optical disc. By this finalizing process, the optical disc has reproduction compatibility and can be reproduced by other optical disc reproducing apparatuses.
As described above, since the optical disc is forcibly finalized after the dubbing is completed, recording of data other than the dubbed continuous program on the optical disc complicates the recording contents of the optical disc and makes it difficult to manage the optical disc. Can be prevented. Therefore, user convenience can be further improved.

  According to the present invention, dubbing of a continuous program from the first medium to the second medium can be performed at an appropriate timing when the capacity of one second medium is accumulated. Therefore, user convenience can be improved.

  Hereinafter, a DVD recorder with HD according to an embodiment of the present invention will be described.

  FIG. 1 is a block diagram showing the configuration of a DVD recorder with HD according to an embodiment of the present invention. The HD-equipped DVD recorder 1 records data input in accordance with a recording instruction on a predetermined medium, and reproduces data that has already been recorded in accordance with a reproduction instruction, and the recording / reproducing section 104 Control unit 2 for controlling the recording operation, the reproducing operation from the recording / reproducing unit 104, and the operation of each unit described below. A television 300 is connected to the DVD recorder 1 with HD.

The recording / playback unit 104 records and reads content data (such as a TV program) with respect to the optical disc drive 20 that records and reads content data (such as a TV program) with respect to the DVD 100 (Digital Versatile Disk) and the built-in HD 30A. An HDD (Hard Disk Drive) 300 and a data processor 40 are provided.
The DVD 100 is a recordable optical disc such as a recordable write-once DVD-R or a rewritable rewritable DVD-RAM. Moreover, the DVD 100 is a single-sided single layer type, and its total capacity is 4, 7 GB (gigabytes).
In this embodiment, the DVD 100 is described. However, a Blu-ray disc may be used for the implementation.

Furthermore, the DVD recorder 1 with HD includes a tuner 102, an encoder 103, a decoder 106, an output unit 107, an OSD generation unit 108, an AV output terminal 109 to which a TV (television) 300 is connected, a user's A receiving unit 110 that receives an operation signal from a remote controller 200 that accepts an input operation, and a storage unit 111 are provided.
The tuner 102 corresponds to the “reception unit” of the present invention. The HD 30A corresponds to the “first medium” of the present invention. The DVD 100 corresponds to a “second medium” of the present invention. The HDD 30 corresponds to the “first recording unit” of the present invention. The optical disk drive 20 corresponds to “second recording means” of the present invention. The remote controller 200 corresponds to the “selecting unit” of the present invention. The television 300 corresponds to the “display unit” of the present invention. The control unit 2 corresponds to the “control unit” of the present invention.

First, recording will be described.
The tuner 102 is connected to an antenna (not shown) that receives a television broadcast signal distributed from, for example, a broadcasting station. Then, the tuner 102 extracts a television broadcast signal of a television program broadcast on the selected channel from the television broadcast signal received by the antenna, and outputs it to the encoder 103. Further, the tuner 102 receives program information indicating channel contents (including program name and broadcast time) several hours ahead, program contents, and the like, and outputs them to the encoder 103.
The program information is, for example, PSI / SI, and the electronic program guide (EPG) is created based on this program information.

The encoder 103 separates the video signal and the audio signal from the television broadcast signal input from the tuner 102. Then, the encoder 103 encodes and compresses the video signal and the audio signal (for example, in MPEG2), and outputs them as content data to the data processor 40. Further, the encoder 103 outputs the program information to the control unit 2.
The encoder 103 adjusts the compression rate in accordance with the image quality mode within the setting conditions set in advance by the user. The image quality mode includes, for example, the highest quality HQ (High Quality) mode recorded at 9 Mbps, the SP (Standard Play) mode recorded at 2 Mbps, and the low quality LP (Long Play) mode recorded at 0, 5 Mbps. There is.

The data processor 40 supplies the content data output from the encoder 103 to one of the optical disc drive 20 and the HDD 30 under the control of the control unit 2.
During dubbing, the data processor 40 supplies the data read from the optical disk drive 20 to the HDD 30 or supplies the data read from the HDD 30 to the optical disk drive 20 according to the control of the control unit 2. .

Next, playback will be described.
The data processor 40 takes in the video / audio data of the DVD 100 from the optical disc drive 20 and supplies it to the decoder 106. Alternatively, the data processor 40 takes in the video / audio data of the HD 30 </ b> A from the HDD 30 and supplies it to the decoder 106.

  The decoder 106 decodes and expands the video / audio data output from the recording / playback unit 104. The decoder 106 is connected to an AV output terminal 109 for supplying the decoded video / audio data to a playback device such as a television.

  The OSD generation unit 108 generates OSD image data indicating an OSD (on screen display) image based on the data input from the control unit 2. Then, the OSD generation unit 108 outputs the OSD image data to the output unit 107.

  The output unit 107 receives OSD image data and video data, selectively receives one of them under the control of the control unit 2, and outputs it to the TV 300 via the AV output terminal 109. Alternatively, the output unit 107 synthesizes the OSD image data and the video data in the video / audio data under the control of the control unit 2 and outputs the synthesized data to the TV 300 via the AV output terminal 109. Further, the output unit 107 also outputs audio data in the video / audio data to the TV 300.

  As described above, the TV 300 reproduces a screen based on video data given via the AV output terminal 109, a screen based on a given composite image signal, or an OSD-only screen based on given OSD image data. Further, the audio signal is also processed by a speaker provided in the TV 300, and the audio is reproduced from the speaker. As a result, the user views the TV program on the TV 300.

  The storage unit 111 is composed of, for example, an EEPROM. The storage unit 111 stores a control program in which a control method for each part of the apparatus main body is described. In addition, the storage unit 111 stores the details of the set recording reservation and the set setting conditions.

The remote controller 200 has a plurality of keys that accept input operations from the user and an infrared LED that transmits an operation signal (command) corresponding to the pressed key (all not shown). The plurality of keys include a recording key that accepts a recording instruction, a reproduction key that accepts a reproduction instruction, and a selection key that accepts selection of whether or not to perform dubbing in FIG. The user performs recording, playback, dubbing, setting conditions, recording reservation setting, and the like by these key operations. The remote controller 200 transmits a control signal corresponding to the operated key from the infrared LED.
The receiving unit 110 receives the operation signal transmitted from the remote controller 200 and transmits the operation signal to the control unit 2.

The control unit 2 is constituted by a microcomputer, for example. The control unit 2 includes a RAM (not shown) as a work field for expanding data processed by the control program stored in the storage unit 111, and a timer circuit (not shown) that measures the current time. Built in.
The control unit 2 controls a data recording operation, a reading operation, and the like with respect to the HD 30A and the DVD 100 according to an operation signal transmitted from the remote controller 200.
Further, the control unit 2 records the program information transmitted from the encoder 103 in the storage unit 111.
When the display of the EPG is instructed, the control unit 2 reads the program information from the storage unit 111 and creates an EPG based on the program information. More specifically, the control unit 2 causes the OSD generation unit 108 to generate the OSD of the EPG based on the program information, and displays the EPG on the television 300.

  The HD-equipped DVD recorder 1 further has a continuous program recording reservation function that allows the user to easily make a reservation for recording a continuous program of a series that is broadcast a plurality of times. Examples of continuous programs include continuous dramas broadcast every week at the same time zone. The HD-equipped DVD recorder 1 having the function uses the above-described program information transmitted from the broadcasting station together with the TV program to identify the TV program that the user is viewing or recording, and for the TV program from the next time onward. Make recording reservations easily. Based on the recording reservation, the DVD recorder 1 with HD records, for example, the continuous drama C broadcasted at the same time zone every week on the HD 30A (see FIG. 2). As a result, the user records a plurality of continuous programs on the HD 30A. Here, the HDD 30 records on the HD 30A based on the program information. As a result, a plurality of continuous programs are recorded in the HD 30A in association with each other.

  FIG. 2 is a diagram showing the contents of a television program recorded on the HD 30A. Program A is an animated program that is broadcast for 30 minutes every Sunday at the same time zone. Program B is a document program that is broadcast for one hour in the same time zone every month. Program C is a continuous drama broadcast for 30 minutes every week at the same time zone.

  Here, the user prepares one DVD 100 for dubbing in the case of the rewritable type while recording a plurality of continuous programs in the HD 30A, or one empty in the case of the write-once type. The DVD 100 is prepared for dubbing and set in the optical disc drive 20. At this time, many users prepare a DVD for each type of continuous program to be stored (according to the type of continuous program to be stored) in order to facilitate management of the DVD. For example, the user prepares a first DVD for storing animation A, a second DVD for storing document program B, a third DVD for storing serial drama C, and the like.

  FIG. 3 is a flowchart showing the operation of the control unit of the DVD recorder with HD according to the embodiment of the present invention. This operation is an operation after each continuous program recording is completed. Specifically, this operation is, for example, immediately after the recording of the continuous program, or when the user makes a recording reservation for the next continuous program after the recording of the continuous program ends.

First, the control unit 2 calculates all the accumulated capacities for each continuous program (S1). For example, it is calculated that the accumulated capacity of all times from the first time to the sixth time of the continuous program A is 3, 0 GB. Further, it is calculated that the accumulated capacity of all times from the first to the third time of the continuous program B is 1, 0 GB. Further, it is calculated that the accumulated capacity of all times from the first to the eighth time of the continuous program C is 4, 6 GB.
Note that a plurality of continuous programs are recorded in the HD 30A in association with each other, so that the control unit 2 can identify a continuous program from a plurality of television programs recorded in the HD 30A.

Next, the control unit 2 estimates the consumed capacity for recording the next continuous program based on the set image quality mode and the broadcast time of the next continuous program (S2). . For example, if the set image quality mode is the LP mode and the program C is a 30-minute program, the consumed capacity (0, 9 GB) is calculated (estimated) using the formula “0, 5 (Mbps) × 1800 (s)”. )
In this embodiment, the consumed capacity is estimated on the basis of the image quality mode and the broadcast time. However, in the implementation, it may be calculated by a formula other than this. Further, considering the CM cut, the capacity may be subtracted from the consumed capacity.

Then, the control unit 2 determines whether or not the sum of the accumulated capacity calculated in S1 and the consumed capacity estimated in S2 exceeds the storage capacity (4, 7 GB) of the DVD 100 (S3). In program C, the accumulated capacity is 4, 6 GB and the consumed capacity is 0, 9 GB, so the total exceeds the storage capacity (4, 7 GB) of DVD 100.
In this embodiment, since the single-sided single-layer DVD 100 is set in the optical disc drive 20, the determination is made with 4, 7 GB. However, the embodiment is not limited to this. For example, in the case of a single-sided, dual-layer DVD, the control unit 2 makes a determination with 9, 4 GB. Here, the storage capacity of the DVD set in the optical disc drive 20 can be grasped by reading the recording management information indicating the type of the DVD.

  If it is determined in S3 that the total does not exceed the capacity of one DVD, the control unit 2 ends this process.

Conversely, if it is determined in S3 that the total exceeds the capacity of one DVD, the control unit 2 displays a guidance message on whether or not to execute dubbing on the OSD (S4). The user sees this guidance message and selects whether or not to execute dubbing with the selection key according to his / her usage method.
If the DVD 100 is not set in the optical disc drive 20 at the timing of S4, the DVD 100 may be set by the user. In this case, the user sees this guidance message and sets the DVD 100 when dubbing is desired. This eliminates the need to set the DVD 100 in advance.

  If execution of dubbing is not instructed (S5), the control unit 2 ends this process.

On the other hand, when the execution of dubbing is instructed (S5), the control unit 2 executes dubbing processing for recording the continuous program recorded on the HD 30A on the DVD 100 (S6). As a result, the continuous program C is dubbed from the HD 30A to the DVD 100 (see FIG. 4).
FIG. 4 is a diagram showing a state in which the continuous program C is dubbed from the HD 30A to the DVD 100.

  When dubbing is completed (S7), the control unit 2 instructs the optical disc drive 20 to perform finalizing processing on the DVD 100 (S8). The reason why S8 is provided is that the ninth and subsequent continuous programs cannot be recorded on the DVD 100. Further, if data other than the continuous program C is recorded in the surplus area of the DVD 100, the recorded content of the DVD 100 becomes complicated and management of the DVD 100 becomes difficult. The finalizing process is a process of physically and logically approaching a ROM type optical disc. In the DVD 100, information regarding the data recording range and recording state is created in this finalization process. By this finalizing process, the DVD 100 has reproduction compatibility and can be reproduced by other DVD reproducing apparatuses.

  Further, after the finalization is completed, the control unit 2 instructs the HDD 30 to delete the continuous program recorded on the DVD 100 by the dubbing process and remaining in the HD 30A (S9). In this embodiment, program C is automatically deleted. And the control part 2 complete | finishes this process. There are mainly two reasons for providing S9. First, it is because a continuous program dubbed on the DVD 100 is useless even if it remains in the HD 30A. The second reason is that the user often deletes manually after dubbing.

  As described above, dubbing of a continuous program from the HD 30A to the DVD 100 can be performed at an appropriate timing when the capacity of one DVD is accumulated. For this reason, the user mistakes the dubbing timing and frequently dubs to the DVD 100 when the capacity of one DVD is not enough, or leaves the HD 30A open even though the capacity of one DVD is accumulated. Disappears. Therefore, DVD management becomes easy. In addition, if a continuous program is dubbed onto a DVD, the continuous program can be deleted from the HD 30A, so that storage management of the HD 30A is facilitated. Therefore, the DVD recorder 1 with HD can improve user convenience.

In addition, since it is possible to select whether or not to execute dubbing according to the usage method of the user, the user-friendliness can be further improved.
In addition, since the DVD 100 is forcibly finalized after dubbing is completed, recording of data other than the dubbed continuous program onto the DVD 100 complicates the recorded content of the DVD 100 and makes it difficult to manage the DVD 100. Can be prevented. Therefore, user convenience can be further improved.
In addition, since the program C is automatically deleted, the space of the HD 30A that is freed by deleting the program C can be used effectively. Therefore, the storage management of the HD 30A is further facilitated, and user convenience can be further improved.
