  In the present embodiment, a case where an image quality correction coefficient based on brightness (illuminance) is calculated using an OPC sensor will be described, but the environment information is not limited to brightness. For example, the color temperature may be measured using an RGB sensor.

  The analog tuner unit 12 selects an analog television broadcast signal received through the antenna 11 for receiving an analog broadcast, and performs channel selection according to a channel selection instruction from the channel selection unit 33. The received signal from the analog tuner unit 12 is separated into an audio signal and a video signal in the AV switch unit 13, the video signal is input to the video selector unit 18, and the audio signal is input to the audio selector unit 26.

  The digital tuner unit 14 selects a digital television broadcast signal received via the digital satellite broadcast receiving antenna 40 or the antenna 11, and selects a channel to be received according to a channel selection instruction from the channel selection unit 33.

The broadcast wave signal extracted by the separation unit (DMUX) 16 is recorded in the memory 7 by writing control by the CPU 6 as necessary.

  The video decoding / capture unit 17 decodes the video data separated by the separation unit (DMUX) 16 and captures video information included in the video data as a still image. The video signal decoded by the video decoding / capture unit 17 is sent to the video selector unit 18. As described above, the video signal from the analog tuner unit 12 is input to the video selector unit 18, and the video signal from the external input unit 31 is also input. The video selector unit 18 selects and outputs one video signal from these input video signals according to the control signal from the CPU 6, and sends it to the video processing unit 19.

  The video processing unit 19 performs video processing such as noise reduction processing, sharpness adjustment, and contrast adjustment on the input video signal so as to obtain an optimal video signal for the liquid crystal display device 22. Convert video data to.

  In addition, the video processing unit 19 acquires a determination result from a content determination unit 41 described later. Also, environmental information is acquired from the OPC sensor 38. Next, an output image quality correction coefficient, which is an image quality correction coefficient used in actual image quality correction, is acquired from the determination result and the environment information. Next, the image quality is corrected using the output image quality correction coefficient, and the moving image whose image quality is corrected is output to the liquid crystal display device 22 via the addition circuit 20 and the display control unit 21. Here, image quality correction is performed gradually in a stepwise manner, for example, when a parameter (index) such as contrast is changed from a certain value to another certain value. That is, at least one value between the certain value and the certain other value (referred to as “half-way value” in this specification) is set, and once the image quality is corrected to the half-way value, Correct the image quality based on a certain value. By doing so, the uncomfortable feeling given to the viewer can be reduced. The larger the halfway value is, the more smoothly the image quality is changed. This can further reduce the sense of discomfort given to the viewer. In addition, it is possible to change the image quality very smoothly by prolonging the time until the shift to the certain value and the certain other value to some extent and by providing more intermediate values. Here, only the case where the image quality is corrected will be described as an example, but the sound quality can also be corrected by a similar operation.

  The display control unit 21 includes a drive circuit for displaying the received video data on the liquid crystal display device 22, and an electronic program table (from the EPG / OSD / reservation processing unit 24) added by the addition circuit 20 ( Electronic program guide (EPG) data or OSD (on-screen display) data is sent to the liquid crystal display device 22 in addition to the video data from the video processing unit 19. The liquid crystal display device 22 displays the transmitted video data on the screen.

  The audio decoding unit 25 decodes the audio data separated by the separation unit (DMUX) 16. The audio decoding unit 25 sends the decoded audio signal to the audio selector unit 26.

  The audio selector unit 26 receives the audio signal from the AV switch unit 13, the audio signal from the external input unit 31, and the audio signal from the audio decoding unit 25, and is selected by the video selector unit 18 under the control of the CPU 6.

  The remote controller light receiving unit 35 is for receiving an optical signal from a remote controller 36 (hereinafter referred to as a remote controller 36) and receiving a control signal from the remote controller 36. Instructions from the viewer, such as transition to scaling display described later, selection and determination of various buttons at the time of scaling display, are performed via the remote controller 36.

  The EPG / OSD / reservation processing unit 24 creates an electronic program guide based on EPG data periodically updated and stored, and draws OSD data stored in the memory 7 in advance. The OSD data is data for drawing various information such as a setting menu screen, a volume cage, a current time, a channel selection, and the like stored in advance in the memory 7, for example.

  Further, the EPG / OSD / reservation processing unit 24 performs program reservation processing (content recording reservation) using the electronic program guide. As described above, the reservation processed data is stored in the memory 7 as reserved program information.

  The communication control unit 34 performs control so as to establish communication via a network such as a telephone line, a LAN, and the Internet.

  The television receiver 10 also includes a content determination unit 41 (content determination unit).

  The content discriminating unit 41 discriminates the type of the content from the members that have received the content among the separating unit 16, the external input unit 31, and the recording / reproducing unit 32. Specifically, it is determined whether the content is a content derived from digital broadcasting, a determination of a frame frequency (for example, whether it is 24 Hz), a determination of whether it is derived from a film (for example, 22 pull-down or a content shot at 24 Hz) If the genre information is associated, the genre information is determined.

  For example, in digital broadcasting, genre information is classified and associated with major classification and middle classification. The major classification includes, for example, “news / report”, “information / wide show”, “variety”, “movie”, “sports”, and the like. As the middle category, for example, when the major category is “news / report”, there are “regular / comprehensive”, “local / region”, “weather” and the like. In general, one broadcast program (content) is associated with a plurality of large categories of genre information. For example, in the case of sports news, genre information of large categories “news / report” and “sports” is associated, and further, some genre information of medium categories belonging to these are associated. When any of the separation unit 16, the external input unit 31, and the recording / playback unit 32 receives content associated with these genre information, the content determination unit 41 acquires genre information associated with the content. can do.

  By the way, the memory 7 stores the image quality correction coefficient in association with the content type and the environment information. Therefore, the content determination unit 41 acquires the image quality correction coefficient corresponding to the determined content type from the memory 7. For example, “if the content type is a digital broadcast program, the genre is“ movie ”, and the content originates from a film and the illuminance is greater than or equal to a predetermined value, an image quality correction coefficient of x is associated”. The image quality correction coefficient is stored in the memory 7 in association with the content type. Next, the content determination unit 41 transmits the acquired image quality correction coefficient to the video processing unit 19. A plurality of genre information may be acquired. That is, a plurality of genre information may be acquired, a plurality of image quality correction coefficients may be acquired based on the plurality of genre information, and transmitted to the video processing unit 19. In this case, if the video processing unit 19 calculates a single image quality correction coefficient by multiplying a plurality of image quality correction coefficients, the image quality correction corresponding to the content genre can be made finely.

  In this embodiment, the case where the content received by the television receiver is a digital broadcast will be described. However, the same processing can be performed for an analog broadcast. For example, in the case of analog broadcasting, voice analysis, image analysis, and the like are performed to extract a keyword representing the type of program as type information, and an image quality correction coefficient is acquired based on the keyword.

  In the above description, the television receiver is particularly described as an example. However, in addition to this, the television is received by a portable device capable of viewing the television, for example, a mobile phone, a car navigation system, a portable game terminal, or the like. Obviously, the display method according to the invention of the present application can also be applied.

  The playback process of the program recorded on the recording medium basically conforms to the process flow when viewing the received broadcast wave. That is, when a program recorded on a recording medium is played back, the video / audio signal included in the recorded program is read from the recording medium by the recording / playback unit 32, and the video signal is sent to the video selector unit 18. The audio signal is sent to the audio selector unit 26. The video signal sent to the video selector unit 18 is displayed as an image by the liquid crystal display device 22 via the video processing unit 19, the addition circuit 20, and the display control unit 21. On the other hand, the audio signal sent to the audio selector unit 26 is output as an audio synchronized with the video displayed on the liquid crystal display device 22 from the speaker 28 via the audio output conversion unit 27.

  On the other hand, recording processing of a program on a recording medium is performed by performing various processing on a broadcast signal received by any of the analog tuner unit 12, the digital tuner unit 14, and the IP broadcast tuner unit 23, Are recorded on the recording medium in a separated state. Specifically, the video signal output from the video selector unit 18 and the audio signal output from the audio selector unit 26 are sent to the external input unit 31 via the bus 8 and are recorded by the recording / reproducing unit 32. Recorded on a recording medium. Note that the video signal output from the video selector unit 18 and the audio signal output from the audio selector unit 26 are recorded on the recording medium in a compressed state with a preset compression rate. The signal compression process is performed by a compression processing unit 37 connected to the bus 8. The compression rate is set by a compression rate setting unit 39 connected to the bus 8.

  The compression processing unit 37 is set by the compression rate setting unit 39 to input the decoded video signal from the video selector unit 18 and the decoded audio signal from the audio selector unit 26. Compression processing is performed according to the compression rate.

  The compression rate setting unit 39 receives the compression rate designated by the user by operating the remote controller 36 via the remote control light receiving unit 35 and sets it as the compression rate of the recorded program. The image quality of recorded video and the quality of audio are determined by the set compression rate. The compression rate set by the compression rate setting unit 39 determines the recording image quality when recording a program, and will be referred to as a recording rate in the following description. The set recording rate is stored in the memory 7 as recording image quality setting information, and is read out as necessary.

  The recording of the program on the recording medium may be performed in real time on a broadcast signal received by any of the analog tuner unit 12, the digital tuner unit 14, and the IP broadcast tuner unit 23, or may be performed by making a recording reservation. .

  The program recording reservation is normally performed by the user selecting a program to be recorded from the electronic program guide. Specifically, the user operates the remote controller from the electronic program guide displayed on the liquid crystal display device 22 of the television receiver 10, selects a program to be recorded, and makes a determination, thereby associating with the selected program. Broadcast time information, channel information, and the like of the received program are acquired and stored in the memory 7 as recorded program information. These processes are performed by the EPG / OSD / reservation processing unit 24 described above.

  As described above, when a program is reserved for recording, the liquid crystal display device 22 stores a recorded list (recorded content list) and a recording reservation (recording) so that the user can perform recording settings while viewing the data in the recording medium. An editing screen is displayed in which the reservation list (recorded reserved content list) and the free space are displayed relatively.

Here, the free capacity means the remaining capacity obtained by subtracting the capacity occupied by the recorded program from the total capacity of the recording medium.

  The notification information creation unit 105 obtains program information (program title information, program title information of a recording medium currently installed in the recording / reproducing unit 32 from recorded program information acquired from the recording medium via the recording / reproducing unit 32. Or the genre information) and the program information (program title information or genre information) of the reserved program (program reserved for recording) obtained from the reserved program information acquired from the memory 7, Create notification information for notifying the user that the program information (program name) of the currently installed recording medium is different from the program information (program name) of the reserved program, and create the notification Information is sent to the edit screen creation unit 101.

  The reserved program list creation unit 106 creates a list of reserved programs from the reserved program information acquired from the memory 7 and sends the list to the editing screen creation unit 101 as reserved program list information.

  The reserved program capacity calculation unit 107 reads the broadcast time of the program and the compression rate corresponding to the recording image quality from the reserved program information acquired from the memory 7, and calculates the recording capacity of the reserved program from these information. . The reserved program capacity information indicating the recording capacity of the reserved program is sent to the editing screen creating unit 101 and the reserved program capacity adjusting unit 108.

  The reserved program capacity adjusting unit 108 adjusts the reserved program capacity calculated by the reserved program capacity calculating unit 107 according to the compression rate read from the acquired recording image quality setting information. The reserved program capacity adjustment unit 108 can also adjust the recording capacity of the reserved program in consideration of the free space of the recording medium calculated by the free space calculation unit 104. Then, the reserved program capacity adjustment unit 108 sends the adjusted recording capacity information to the editing screen creation unit 101 and the TAB conversion processing unit 109.

  From the adjusted recording capacity information acquired from the reserved program capacity adjusting unit 108, the TAB conversion processing unit 109 exceeds the recording capacity of the recording medium, and the recording capacity of the reserved program to be recorded on the recording medium is set on a plurality of recording media. When recording should be performed separately, TAB information for displaying each recording medium in TAB format is created, and the created TAB information is sent to the edit screen creation unit 101.

  The recording image quality setting screen creation unit 110 is a unit that creates a recording image quality setting screen for displaying the above-described recording image quality setting information display frame 205. From the acquired recording image quality setting information, the currently set recording quality setting screen is displayed. A screen specifying the image quality is created and sent to the editing screen creation unit 101 as the recording image quality setting screen information.

  The edit screen creation unit 101 includes thumbnail information from the thumbnail processing unit 102, recorded program list information from the recorded program list creation unit 103, free space information from the free space calculation unit 104, and notification information creation. Notification information from the unit 105, reserved program list information from the reserved program list creation unit 106, adjusted recording capacity information from the reserved program capacity adjustment unit 108, TAB information from the TAB processing unit 109, recording video quality Information for creating an editing screen necessary for content editing (content recording / editing) is created from the recording image quality setting screen information from the setting screen creation unit 110 and sent to the display control unit 21 as editing screen creation information.

  The display control unit 21 displays an editing screen on the liquid crystal display device 22 from the acquired editing screen creation information.

  Here, the edit screen will be briefly described. FIG. 3 is a diagram illustrating an example of the editing screen.

  The editing screen 201 shown in FIG. 3 includes a recorded program list display frame 202 for displaying a list of programs recorded on the recording medium currently installed in the television receiver 10 shown in FIG. The screen layout has at least three display frames set: a reserved program list display frame 203 for displaying a list of programs and a recording medium capacity state display frame 204 for displaying the capacity state of the recording medium. In addition, the editing screen 201 displays the recording image quality setting information display frame 205 for displaying information related to the setting and status of the recording image quality of the program, and the type of the recording medium currently installed in the television receiver 10. A recording medium type display frame 206 is displayed.

  In the editing screen 201, a recording reservation execution button 207 and a reservation cancel button 208 are displayed. The recording reservation execution button 207 is associated with a function for executing recording reservation of a program, and the reservation cancel button 208 is associated with a function for executing cancellation of recording reservation of a program. The user can select and execute a desired button by performing a predetermined operation (such as a remote control operation).

  In the example shown in FIG. 3, the recorded program list display frame 202 is displayed at the left end of the editing screen 201, the reserved program list display frame 203 is displayed at the right end of the screen, and a program is recorded between both lists. A graphic medium (disc-shaped) recording medium capacity state display frame 204 that is an image of a BD as a recording medium is displayed.

  In the lower part of the editing screen 201, a recording image quality setting information display frame 205 displaying information for setting the recording image quality (recording rate) is displayed. “▲” displayed in the recording image quality setting information display frame 205 indicates the currently set recording rate. That is, if the “▲” displayed in the recording image quality setting information display frame 205 is moved to the left by a predetermined operation, the recording rate decreases, and if it is moved to the right, the recording rate increases.

  Note that the display position of each display frame on the editing screen 201 is not limited to the arrangement shown in FIG. 3 because it may be arranged so that the user can easily use it.

  Further, the recording medium capacity state display frame 204 includes a recorded program capacity display area 204a as an area occupied by recorded content, a recording reserved program capacity display area 204b as an area occupied by a program (content) to be reserved, and a recorded content. And a remaining capacity display area 204c indicating the remaining capacity of the BD excluding the reservation desired content. Here, in the recording medium capacity state display frame 204, the ratio of each area is displayed as a pie chart.

  When recording a reserved program on a recording medium, the user simply checks the editing screen 201 shown in FIG. 3 to determine whether or not the reserved program can be recorded on the recording medium currently installed in the apparatus. Also, it is possible to easily grasp how much capacity is consumed if recording is possible by simply checking the pie chart.

  In the editing screen 201 shown in FIG. 3, only the supermen (movies) are displayed in the recorded program list display frame 202 as programs already recorded on the BD that is the recording medium displayed in the recording medium type display frame 206. In the reserved program list display frame 203, two programs of Supermen 2 (movie) and Supermen 3 (movie) are displayed as reserved programs acquired from the reserved program information stored in the memory 7. .

  In the recording medium capacity state display frame 204, the recording time (2 hours 30 minutes) of the supermen (movies) displayed in the recorded program list display frame 202 is displayed in the recorded program capacity display area 204a. In the recording reserved program capacity display area 204b, the recording time (3 hours 30 minutes) when supermen 2 (movie) and supermen 3 (movie) displayed in the reserved program list display frame 203 are recorded is displayed. In the remaining capacity display area 204c, the recordable time (2 hours) calculated from the remaining capacity is displayed.

  From the editing screen 201, even if the user records a reserved program 3 hours 30 minutes to be recorded on a recording medium having a recorded program 2 hours 30 minutes, there may still be a remaining capacity (free space) of 2 hours. Visible.

  Furthermore, it is possible to visually confirm that the recorded program (Supermen) of the same series is recorded on the recording medium that is the recording destination medium of the program (Supermen 2 and 3) for which recording has been reserved, and mistakes in the work of the same series It is possible to visually recognize that the data can be recorded on the medium.

  The editing screen 201 shown in FIG. 3 is also sufficient for improving user convenience, but it is difficult to imagine or grasp the contents of the recorded program displayed in the recorded program list display frame 202. There is also. In such a case, the thumbnail display of the recorded program may be performed.

  FIG. 4 shows an example in which thumbnails of recorded program videos are displayed on the editing screen 201 shown in FIG.

  As shown in FIG. 4, the thumbnail is displayed on a thumbnail display unit 202 a provided in an empty area of the recorded program list display frame 202 displayed on the editing screen 201.

  The thumbnail displayed on the thumbnail display unit 202a may be a still image or a moving image. However, in any case, it is necessary not to select a video unrelated to the contents of the recorded program, for example, a commercial video.

  The thumbnail processing as described above is performed in the thumbnail processing unit 102 described above.

  3 and 4, on the editing screen 201, the recording medium capacity state display frame 204 has a circular shape for displaying each region using a pie chart as described above. This is because the recording medium makes it easy to image a disk-shaped BD or the like.

  Further, in the recording medium capacity state display frame 204, what percentage of the total capacity is displayed in each area (recorded program capacity display area 204a, recording reserved program capacity display area 204b, remaining capacity display area 204c). In order to visually confirm whether or not the recording capacity is in the pie chart, the recording capacity of each area is displayed in a size (area) proportional to the ratio of the total capacity.

  In the example shown in FIGS. 3 and 4, the recording rate displayed in the recording image quality setting information display frame 205 indicates the area of each region when recording is performed with an SP indicating standard image quality. Here, in the recording medium capacity state display frame 204, although the size of the recorded program capacity display area 204a corresponding to the recorded program that has been recorded on the recording medium cannot be changed, it is still to the recording medium. The size of the recording reservation program capacity display area 204b in which the recording of the recording is not completed can be changed. The size of the remaining capacity display area 204c is changed in accordance with the change in the size of the recording reserved program capacity display area 204b.

  In the recording reserved program capacity display area 204b, the area on the pie chart can be changed by changing the recording image quality of the reserved program, that is, the recording rate.

  For example, if the recording image quality is lowered from SP, the compression rate increases, so that the recording capacity decreases if the recording time is the same. As a result, the area of the scheduled recording program capacity display area 204b in the pie chart showing the recording medium capacity state display frame 204 is reduced. On the contrary, when the recording image quality is increased from SP, the compression rate is lowered, so that the recording capacity increases if the recording time is the same. As a result, the area of the scheduled recording program capacity display area 204b in the pie chart showing the recording medium capacity state display frame 204 is increased.

  In this way, by adjusting the recording image quality, the user can visually confirm how much the capacity of the program to be recorded occupies in the recording medium capacity state display frame 204.

  Here, the recorded image quality is referred to as a recording rate. The recording rate is low when the data compression rate is high, and is high when the data compression rate is low. That is, when the recording rate of the reserved program is increased, the area occupied by the reserved program in the pie chart showing the recording medium capacity state display frame 204 is increased, and when the recording rate of the reserved program is decreased, the recording medium capacity state is increased. The area occupied by the reserved program in the pie chart showing the display frame 204 is reduced.

  The recording rate can be confirmed or changed in the recording image quality setting information display frame 205 displayed on the editing screen 201 described above. For example, the recording rate can be confirmed by “▲” in the recording image quality setting information display frame 205 shown in FIG. In FIG. 3, “▲” indicates an SP that is a recording rate indicating standard image quality. Further, this “▲” can be moved left and right by operating a remote control of the television. That is, in the recording image quality setting information display frame 205, it is possible to change the recording image quality, that is, the recording rate, by moving “▲” to the left and right.

  The recording rate and the compression rate are associated with each other and stored in advance in the memory 7 or the like, and the above-described compression rate setting unit 39 (FIG. 1), when the recording rate is changed by a remote controller or the like as described above, The compression rate associated with the changed recording rate is read from the memory 7 and set as the compression rate for program recording.

  Therefore, by changing the recording rate as described above, the program recording compression rate is changed.

  In the following, in the pie chart showing the recording medium capacity state display frame 204, the area change of the recording reserved program capacity display area 204b accompanying the change of the recording rate, that is, the change of the recording capacity when the reserved program is recorded is shown in FIG. This will be described with reference to FIGS.

  In the recording medium capacity state display frame 204 shown in FIG. 3, the remaining capacity in the remaining capacity display area 204c is 2 hours. This remaining capacity is the remainder subtracted from the recording capacity occupied by the recording reservation program capacity display area 204b when it is assumed that the recording rate is set to SP indicating standard image quality.

  In this case, the recording capacity occupied by the recording reserved program capacity display area 204b can be increased up to the recording capacity for two hours when recording is performed at the recording rate SP of the standard image quality. As described above, since the recording rate can be increased by increasing the recording capacity, the reserved program can be recorded with higher image quality than the standard image quality.

  5A and 5B occupy the recording reserved program capacity display area 204b in the recording medium capacity state display frame 204 when the recording rate SP of standard image quality shown in FIG. 3 is changed to the recording rate XP of slightly higher image quality. It is the figure which showed the recording capacity.

  As shown in FIG. 5B, it can be seen that the recording capacity occupied by the remaining capacity display area 204c is reduced by the increase in the recording capacity occupied by the recording reserved program capacity display area 204b. However, the remaining capacity display area 204c has a recordable time of 10 minutes as the remaining capacity. In this case, 10 minutes indicates a recordable time when recording is performed at a recording rate XP that shows a slightly higher image quality, as shown in FIG.

  As described above, the change of the recording rate is realized by moving the “▲” shown in the recording image quality setting information display frame 205 to the left and right by a predetermined operation while checking the editing screen 201. Yes. In this case, the recording capacity occupied by the recording reserved program capacity display area 204b in the recording medium capacity state display frame 204 increases or decreases in conjunction with the left / right movement of “▲”.

  This mechanism is explained as follows.

  When the user gives an instruction to move “▲” on the editing screen 201 to the right by using the remote controller, for example, the compression rate setting unit 39 shown in FIG. 2 reads the compression rate associated with the moving direction from the memory 7. The read compression rate is sent to the compression processing unit 37. The compression processing unit 37 sends the acquired compression rate to the CPU 6 as recording image quality setting information. In the CPU 6, the capacity adjustment is performed by the reserved program capacity adjustment unit 108 shown in FIG. 1, and the adjusted capacity information is sent to the editing screen creation unit 101. The editing screen creation unit 101 determines the area occupied by the scheduled recording program capacity display area 204b in the recording medium capacity state display frame 204 based on the adjusted capacity information. Such a series of processing is performed in conjunction with the right and left movement of “▲”. The same applies to the examples described below.

  In this way, the user can freely adjust the recording rate within the editing screen 201.

  For example, the current reserved program (Supermen 2 and 3) is recorded from the contents displayed on the editing screen 201 shown in FIG. 3, and the recorded program (Supermen) and the same series trilogy are recorded on one recording medium. 3 may be set as the ratio of each area of the recording medium capacity state display frame 204 shown in FIG. 3, or the recording capacity occupied by the scheduled recording program capacity display area 204b is increased so that the recording medium has free space. It is also possible not to leave it. In this case, the area occupied by the recording reserved program capacity display area 204b is defined as the maximum area.

  In the case shown in FIG. 5B, 10 minutes of remaining capacity remains, but it is also possible to use this 10-minute recording capacity for the scheduled recording program capacity display area 204b. In this case, the “▲” shown in FIG. 5A may be moved from the slightly high-quality XP to the high-quality FINE side.

  In this way, it is possible to move the “▲” shown in the recording image quality setting information display frame 205 to maximize the area occupied by the recording reserved program capacity display area 204b. For example, FIG. As shown in FIG. 6B, a button 209 “Record using the entire recording area” is further provided in the recording image quality setting information display frame 205, and the user selects this button 209. As shown, the area occupied by the scheduled recording program capacity display area 204b may be the maximum area.

  The process of making the area indicated by the recording reserved program capacity display area 204b when the button 209 is used as described above the maximum area is realized as follows.

  For example, when the user gives an instruction to select the button 209 shown in FIG. 6A by remote control operation, the compression rate setting unit 39 shown in FIG. 2 reads the free space of the current recording medium, the reserved program from the memory 7. The recording time is acquired, and the compression rate in the case where all the free space is used for recording the reserved program is calculated, and the calculated compression rate is sent to the compression processing unit 37. The compression processing unit 37 sends the acquired compression rate to the CPU 6 as recording image quality setting information. In the CPU 6, the capacity adjustment is performed by the reserved program capacity adjustment unit 108 shown in FIG. 1, and the adjusted capacity information is sent to the editing screen creation unit 101. The editing screen creation unit 101 determines the area occupied by the scheduled recording program capacity display area 204b in the recording medium capacity state display frame 204 based on the adjusted capacity information.

  In the above example, the recording rate adjustment for recording a trilogy of a recorded program (Supermen) and a reserved program (Supermen 2 and 3) on a single disc has been explained. In consideration of recording the program (Supermen 4) on the same disk, conversely, it is necessary to reduce the recording capacity occupied by the recording reserved program capacity display area 204b.

  In this case, as shown in FIG. 7A, the user moves the “▲” indicating the recording rate to the left and moves the remaining capacity in the pie chart of the recording medium capacity state display frame 204 shown in FIG. 7B. The remaining capacity of the display area 204c is confirmed, and when the time required for the remaining capacity (2 hours and 10 minutes) is indicated, the above movement of “” ”is stopped. As shown in FIG. 7A, the recording rate for recording the reserved program in this state is set to a recording rate that shows an image quality (low image quality) slightly lower than the standard image quality indicated by the recording rate SP.

  Up to this point, the description has been made assuming that the number of reserved programs is small and the recording is performed on one disk. However, if the number of reserved programs is large, one disk can be recorded even if the recording rate is lowered. There is a possibility that it cannot be recorded. In such a case, the following TAB processing is performed.

  FIG. 8 shows a reserved program list displayed in the reserved program list display frame 203. This reserved program list indicates that the number of reserved programs is 10.

  In the content editing apparatus 100 shown in FIG. 1, the reserved program capacity adjustment unit 108 calculates the reserved program capacity for the reserved program list shown in FIG. 8 and sends it to the TAB processing unit 109. In the TAB conversion processing unit 109, in order to record all the reserved programs from the preset recording capacity per disc and the reserved program capacity sent from the reserved program capacity adjusting unit 108, a preset value is set. In the case of the recording rate, the number of discs required is calculated, and the TAB information for converting the reserved program list that can be recorded on one disc into a TAB according to the required number of discs is an edit screen creation unit 101.

  FIG. 9A to FIG. 9C are diagrams showing the TAB-programmed reserved program list display frame 213 created by the editing screen creation unit 101 from the TAB information.

  This TAB conversion displays the program in the reserved program list shown in FIG. 8 divided into the required number of disks based on the capacity (recordable capacity) of the disk, which is the current medium, and the recording rate. It is a kind of reserved program list. Note that the first TAB indicates up to which of the reserved programs can be recorded with respect to the free space of the currently installed disc, and the remaining TAB contains all the same recordings as the currently installed disc. When a capacity disk is assumed, a list of reserved programs that can be recorded is displayed. However, since the free capacity of the currently installed disc assumes the recording capacity already occupied by the recorded program minus the total recording capacity, if there is no recorded program, The total capacity that can be used for recording is the above-mentioned empty capacity.

  As shown in FIG. 9A, TAB1 in the reserved program list display frame 213 can record up to (1) and (2) of the reserved program with respect to the remaining amount of the current disk, and (3) of the reserved program In order to record (10), it can be visually recognized that two more discs are required.

  Here, as described above, the number of discs in the TAB conversion depends on the recording rate. Therefore, if the recording rate is lowered, the recording capacity of one program can be reduced although the image quality is lowered accordingly. That is, if the recording rate is lowered, the recording time on the disc can be increased.

  For example, as shown in FIG. 10 (a), if the recording rate is controlled to a low image quality and the capacity is increased by a predetermined operation, the recording time per disc increases, so that shown in FIGS. 10 (b) and 10 (b). Thus, the TAB changes to the reserved program list display frame 223 having three to two TABs, and the user can visually recognize that two disks are enough to record all the reserved programs shown in FIG.

  Conversely, as shown in FIG. 11 (a), when the recording rate is manipulated to reduce the recording quality and capacity by a predetermined operation, the recording time that can be recorded per disc is reduced. In addition, the TAB changes to the reserved program list display frame 233 having five TABs, and the user can visually recognize that five discs are required to record all the reserved programs shown in FIG. 8 with high image quality.

  In the content editing apparatus 100, the recorded program list display frame 202 and the reserved program list display frame 203 are displayed simultaneously on the editing screen 201 as shown in FIG. It is also possible to operate the recorded program list displayed in the program list display frame 202 and reflect it in the reserved program list displayed in the reserved program list display frame 203.

  For example, as shown in FIG. 12A, when two programs are recorded on the currently installed disc and the number of reserved programs is four, the TAB is converted based on the reserved program list as described above. 12B and 12C, a reserved program list display frame 243 having two TABs is obtained. Here, only the three reserved programs displayed in the reserved program list display frame 243 of TAB1 shown in FIG. 12 (b) can be recorded on the currently mounted disc, and TAB2 supporting FIG. 12 (c). It can be visually recognized that one reserved program displayed in the reserved program list display frame 243 cannot be recorded on the currently mounted disc.

  In such a case, if the example shown in FIGS. 10A to 10C is used, the fourth reserved program is operated by operating the recording rate (lowering the image quality, expanding the capacity (increasing the recording time)). Is recorded on the currently installed disc.

  Here, by deleting one of the recorded programs displayed in the recorded program list display frame 202, the free space of the disk is increased, so that the recording rate remains as it is and the currently installed disk has 4 The case where all the reserved programs can be recorded will be described below with reference to FIGS. 13 (a) and 13 (b) and FIGS. 14 (a) and 14 (b).

  The user performs a predetermined operation using a remote controller or the like, and selects one recorded program from the two recorded programs displayed in the recorded program list display frame 202. To select a recorded program. FIG. 13A shows an example in which “Dracon Bowl” of the recorded program (2) is selected. This selection is made based on the determination that the user may delete the selection.

  In the state of the recorded program list display frame 202 shown in FIG. 13A, there are still two TABs as shown in FIG. 13B, but the selected recorded program is deleted by a predetermined operation. As shown in FIG. 14A, if one recorded program is displayed in the recorded program list display frame 212, as shown in FIG. 14B, a reservation consisting of one TAB is made. All reserved programs are listed in the program list display frame 253. As a result, all reserved programs can be recorded on the currently loaded disc.

  Thus, as shown in FIG. 14A, when a recorded program is deleted, all the reserved programs can be recorded on the current disk, and the program originally in TAB 2 (FIG. 12C). ) Is added to the list of TAB1, and TAB2 becomes a reserved program list display frame 253 which has disappeared as shown in FIG.

  Since the above series of operations is a simulation of whether or not all recording can be performed on the currently mounted disc, the recorded program recorded on the disc is not actually deleted. As shown in (a) and (b), when it is found that all reserved programs can be recorded on one disc, the recorded program may be actually deleted by a user operation.

  If the recording capacity of the reserved program to be recorded additionally is larger than the recording capacity occupied by the recorded program to be deleted, it is necessary to lower the recording rate or change the recording program to be deleted. is there. In such a case, since TAB2 does not disappear, this allows the user to visually recognize that not all the reserved programs can be recorded on the disk even if the selected recorded program is deleted.

  By the way, if the program to be recorded is a continuous drama, if the same program is continuously recorded on one disc for each program, by setting in advance to record the continuous drama, for example, it is already recorded on the disc. It is detected whether or not the existing program and the reserved program match, and if they match, the reserved program is recorded on the disc.

  If the reserved program is different from the program already recorded on the disc, the fact is notified to the user. As such notification means, there is a notification information creation unit 105 shown in FIG. When the reserved program is different from the recorded program, the notification information creating unit 105 alerts the release notification area 201a displayed in the OSD in the central portion of the editing screen 201 as shown in FIG. I am trying to make a reservation for a program that is different from "

  In addition, when recording a genre of a program to be recorded on a disc, for example, if it is a movie as a genre, only a movie, if it is a sport, if only a sport is recorded on a single disc, Is set, for example, it is detected whether or not the genre of the program already recorded on the disc and the genre of the reserved program match, and if they match, the reserved program is recorded on the disc.

  If the genre of the reserved program is different from the genre of the program already recorded on the disc, the user is notified accordingly. As such notification means, there is a notification information creation unit 105 shown in FIG. When the genre of the reserved program is different from the genre of the recorded program, the notification information creation unit 105 alerts the release notification area 201a displayed in the OSD in the central portion of the editing screen 201 as shown in FIG. The message “Cannot record because the genre is different from the program recorded on the BD. If you want to remove this restriction ...” is displayed and recording is prohibited.
