Moreover, since these recording apparatuses can record a program for a long time, the case where the recorded program is left without viewing is increasing.
Also, if the remaining capacity of the HDD is insufficient at the time of recording reservation setting, for example, a warning message such as “Cannot set scheduled recording due to insufficient remaining capacity” will be displayed on the display device connected to the recording device. It has become. In this case, the user deletes the program data (program data) already recorded in the HDD to secure the remaining capacity, and then sets the recording reservation again.
In addition, when a weekly recording reservation is made, a reserved program is recorded every week, so that the remaining capacity of the HDD may be insufficient during recording. In that case, the recording apparatus performs overwriting recording in order from the oldest unprotected program data that is not set to be non-erasable, or stops recording itself.
When an arbitrary video file is selected from the list in the recording menu screen by the user, the recording reservation screen is displayed on the monitor to enable recording reservation, the recording reservation is completed, and the recording operation mode is entered. Then, when the video data is recorded in the selected area on the HDD and the video data is recorded until the selected area is full, if the recording operation does not end, the video is recorded in the free area on the HDD. Continue recording data. Further, when the playback menu screen is selected, the playback mode screen is displayed on the monitor, and any video file is selected from the list in the playback menu screen. When playing back video data recorded in the video file and playing back any video data from the hard disk, or overwriting new video data on top of any video data already recorded on the hard disk In some cases, the video data desired by the user can be reproduced or overwritten on the video data desired by the user by an extremely simple operation (see, for example, Patent Document 1).
In addition, the remaining amount of signal recording is detected from the predetermined recording capacity of the information recording area, and when an overwriting recording display section and a capacity shortage display section provided on the front panel of the hard disk recorder main body and a reserved recording instruction are received, When the storable recording capacity is insufficient for the reserved recording time, the capacity shortage display section is displayed, and the reception of broadcast radio waves is being recorded in the information recording area. When starting overwrite recording, display the capacity shortage display section and display the file to be erased on the display section in a preset priority order, then selectively erase the file according to the erase command, By performing signal overwrite recording, there is a shortage of remaining capacity when recording to the hard disk, overwriting to necessary files, etc. Display easily noticed over THE, there is always those as to enable appropriate recording (for example, see Patent Document 2).

  The tuner 101 selects a predetermined channel from the received signal corresponding to the radio wave received by the antenna 1 and supplies the video / audio signal of that channel to the MPEG compression unit 102.

  The MPEG compression unit 102 converts the video / audio signal supplied from the tuner 101 into digital video / audio data, performs compression processing by, for example, the MPEG-2 method, and supplies the compressed video / audio data to the writing unit 103. It is supposed to be.

  The writing unit 103 supplies the video / audio data supplied from the MPEG compression unit 102 to the HDD 104 under the control of the control unit 105 and writes the data.

  The HDD 104 has a magnetic head (not shown), a servo circuit, a metal disk coated with a magnetic material, and the like. The servo circuit rotates and drives the disk while the magnetic head supplies the video / audio data supplied from the writing unit 103. It is supposed to be recorded on a disc. In addition to the video / audio data, management data is also recorded on the disc. In this case, the recording area of the disc is divided into an information recording area on the outer peripheral side and a management information area on the inner peripheral side, video / audio data is recorded in the information recording area, and management data is recorded in the management information area. be able to.

  The reading unit 106 reads the video / audio data recorded on the HDD 104 under the control of the control unit 105 and supplies the video / audio data to the MPEG decompression unit 107.

  The MPEG decompression unit 107 performs decompression processing on the video / audio data supplied from the reading unit 106, supplies video data to the synthesis processing unit 108 among the decompressed video / audio data, and converts the audio data into analog audio. After being converted into a signal, it is supplied to the speaker 3.

  Under the control of the control unit 105, the synthesis processing unit 108 generates synthesized video data by synthesizing the video / audio data supplied from the MPEG decompression unit 107 and the display data supplied from the control unit 105. After being converted to a signal, it is output to the display device 4.

  The font data storage unit 109 stores bitmap image data corresponding to various graphics such as various fonts and cursors, and the bitmap image data corresponding to characters and graphics to be superimposed on the video data is appropriately read out by the control unit 105. It is supposed to be.

  The setting data storage unit 110 stores various setting values to be described later under the control of the control unit 105. The operation unit 112 is operated when inputting various commands and data, and supplies the input commands and data to the control unit 105.

  The receiving unit 111 receives infrared rays emitted from the remote controller (remote controller) 2 and supplies a command corresponding to the infrared rays to the control unit 105.

  Under the control of the control unit 105, the communication control unit 113 is configured to transmit various notification mails (to be described later) to a predetermined mail address set in advance.

  Next, the operation of the present embodiment will be described with reference to the flowchart of FIG. First, in step S1, the control unit 105 determines whether or not the user has operated the operation unit 112 or the remote control 2 to instruct display of a list of reserved programs. As a result, when it is determined that the display of the list of reserved programs is not instructed, the process proceeds to step S5. On the other hand, if it is determined that the display of a list of reserved programs is instructed, the process proceeds to step S2.

  In step S2, the control unit 105 reads data indicating a reserved program from the setting data storage unit 110, and generates display data for displaying a list of reserved programs. At that time, bitmap image data corresponding to characters and graphics to be displayed is read from the font data storage unit 109 as necessary.

  In addition, bitmap image data corresponding to the cursor is read from the font data storage unit 109, display data in which the cursor is superimposed on the reserved program list is generated, and supplied to the synthesis processing unit 108. When the cursor movement is instructed by the operation of the remote controller 2 or the operation unit 112, new display data in which the cursor is superimposed on a predetermined position of the movement destination is generated and supplied to the composition processing unit 108.

  The synthesis processing unit 108 generates synthesized video data obtained by superimposing the display data supplied from the control unit 105 on the video data supplied from the MPEG decompression unit 107, converts the generated video data into an analog video signal, and then displays it on the display device 4. Supply. As a result, a composite video in which the reserved program list and the cursor are superimposed on the video of the predetermined channel selected by the tuner 101 is displayed on the screen of the display device 4.

  FIG. 3 shows an example of a reserved program list display screen displayed on the display device 4. As shown in the figure, the reserved program list display screen includes a unique number assigned to each reserved program, a program name (reserved name) of each reserved program, a channel number (CH), a date, and a broadcast start. Time and broadcast end time (start-end), image quality (recording mode), recompression indicating whether recompression is possible or not, compression rate at the time of recompression (recompression rate), HDD remaining capacity, Consists of

  In the reserved program list display screen of FIG. 3, the image quality “XP” represents the highest image quality mode, the image quality “SP” represents the standard image quality mode, the image quality “LP” represents the long-time recording mode, and the image quality “EP” is long. It represents the time recording mode. When the image quality is set in the manual setting mode, a predetermined image quality represented by a value of 1.4 to a value of 9.2 can be set according to the length of the recordable time. A value of 1.4 represents the lowest image quality that can be set in the manual setting mode, and a value of 9.2 represents the highest image quality.

  Next, in step S <b> 3, the control unit 105 determines whether the user has operated the operation unit 112 or the remote controller 2 to move the cursor and selected a desired program. As a result, when it is determined that the user has not selected a desired program, the process of step S3 is repeatedly executed. On the other hand, if it is determined that the user has selected a desired program, the process proceeds to step S4.

  In step S4, a reserved program setting screen is displayed. On this reserved program setting screen, the importance (priority) of each program can be set. This importance (priority) is represented by whether or not erasure is possible, and if erasure is impossible, whether or not recompression is possible. That is, it is set that the program having the lowest importance can be deleted. When the importance is higher than that of the program and erasure is impossible, re-compression is possible and a re-compression rate is set. The recompression rate is set higher as the importance of the program is lower, and is set lower as the importance is higher. In the case where the importance is the highest, erasure is impossible, and recompression is not possible, it is set that the video recording should be protected.

  Further, the value of the remaining capacity of the HDD 104 (reference value of remaining capacity), which is a reference for erasing or recompressing, can be set on a predetermined reference remaining capacity setting screen. The reference value of the remaining capacity can be arbitrarily set by the user, but the reference value obtained by the control unit 105 by a predetermined method may be set.

  4 to 6 show examples of reserved program setting screens for setting various setting values of the reserved recording program. As shown in the figure, the setting screen includes “program name (reserved name)”, “channel number (CH)”, “recording date”, “broadcast start time (start)”, “broadcast end time (end) ) "," Image quality "," Sound quality "," Genre "," Erase / recompressability (recompression) "," Recompression rate "," Email notification presence (email notification) "," Notification address " , The title of each setting item such as “Program Description”, and an input field for inputting the contents of each setting item.

  In the reserved program setting screen shown in FIG. 4, “K1 dynamite” is set for the setting item “reserved name”, “8” is set for the setting item “CH (channel number)”, and “recording date” is set for “setting date”. “2005/02/07 (Month)”, “10:00” for the setting item “Start”, “11:00” for the setting item “End”, “XP” for the setting item “Image quality”, and “ “Sound quality” is “standard”, the setting item “genre” is “sports”, the setting item “recompression” is the most important and “1 (protection)” indicating that recompression is not possible, “Recompression rate” is not set, “Yes” is set for the setting item “Email notification”, “taro@sharp.co.jp” is set for the setting item “Notification address”, and “K1” is set for the setting item “Program description”. "Dynamite" is set for each. Therefore, even if the remaining capacity of the HDD 104 is insufficient after recording, this program is not deleted or recompressed.

  In the reserved program setting screen shown in FIG. 5, the setting item “reservation name” is “world cup qualifying tournament”, the setting item “CH (channel number)” is “10”, and the setting item “recording date” is set. Is “2005/02/09 (Wed)”, the setting item “start” is “21:00”, the setting item “end” is “23:00”, the setting item “image quality” is “XP”, The item “sound quality” is “standard”, the setting item “genre” is “sports”, the setting item “recompression” is “2 (compressible)” indicating that recompression is possible, and the setting item “recompression” "Rate" for the "Rate" setting, "Yes" for the setting item "Mail notification", "taro@sharp.co.jp" for the setting item "Notification address", and "World cup" for the setting item "Program description" "Asia Final Qualifier" is set for each. Therefore, this program may be recompressed if the remaining capacity of the HDD 104 is insufficient after recording.

  In the reserved program setting screen shown in FIG. 6, the setting item “reservation name” is “BS news”, the setting item “CH (channel number)” is “BS7”, and the setting item “recording date” is “ "2005/02/15 (Tue)", the setting item "start" is "18:00", the setting item "end" is "18:30", the setting item "image quality" is "SP", and the setting item " “Standard” for sound quality, “news” for setting item “genre”, “3 (erasable)” indicating that the setting item “recompression” is the least important and can be deleted, and setting item “ “Recompression rate” is not set, “Yes” is set for the setting item “Mail notification”, “taro@sharp.co.jp” is set for the setting item “Notification address”, and “BS” is set for the setting item “Program description”. News "is set for each. Therefore, this program may be deleted if the remaining capacity of the HDD 104 is insufficient after recording.

  In step S4, when the setting of various setting values related to each reserved program on the reserved program setting screen is completed, the setting values are supplied to and stored in the setting data storage unit 110. Then, the process returns to step S1, and the processing after step S1 is performed. Is repeatedly executed. The setting data storage unit 110 can be configured by a nonvolatile memory or the like that retains data even when the power is turned off. Alternatively, the setting value can be recorded in the HDD 104.

  On the other hand, if it is determined in step S1 that the display of the reserved program is not instructed, the process proceeds to step S5. In step S5, the control unit 105 determines whether there is a reserved program reserved for recording. The data related to the reserved program includes data of each setting item set on the reserved program setting screen shown in FIGS. 4 to 6 and the like, and is stored in the setting data storage unit 110. If it is determined in step S5 that there is no reserved program reserved for recording, the process returns to step S1 and the processes in and after step S1 are repeatedly executed. On the other hand, if it is determined that there is a reserved program reserved for recording, the process proceeds to step S6.

  Next, in step S <b> 6, the control unit 105 determines whether or not the remaining capacity of the HDD 104 is less than a set predetermined reference value. As a result, when it is determined that the remaining capacity of the HDD 104 is not less than the reference value (greater than or equal to the reference value), the process returns to step S1, and the processes after step S1 are repeatedly executed. On the other hand, when it is determined that the remaining capacity of the HDD 104 is less than the predetermined reference value, the HDD recorder 100 transmits a remaining capacity shortage notification mail as shown in FIG.

  That is, the control unit 105 generates message data indicating that the remaining capacity of the HDD 104 is insufficient, supplies the message data and a preset mail address to the communication control unit 113, and the message data is transmitted to the communication unit 113. Command to send to e-mail address. This e-mail address can be arbitrarily set in advance.

  Based on a command from the control unit 105, the communication control unit 113 transmits the message data supplied from the control unit 105 to the mail address supplied from the control unit 105 via a network such as the Internet.

  As shown in FIG. 7, in this example, the shortage remaining notification mail is the sender's mail address “XXXXXX@XXX.jp” and the subject “HDD remaining capacity shortage notification”. ]. Then, it progresses to step S7.

  In step S7, based on the setting contents of the setting item “recompression” of each reserved recording program stored in the setting data storage unit 110 by the control unit 105, there is an erasable program among the already recorded programs. It is determined whether or not there is. Programs whose setting item “recompress” is set to “3 (erasable)” can be erased.

  As a result, if it is determined that there is no erasable program, the process proceeds to step S10. On the other hand, if it is determined that there is an erasable program, the process proceeds to step S8.

  In step S8, first, the HDD recorder 100 transmits a program deletion schedule notification mail as shown in FIG. That is, the control unit 105 generates message data indicating that the program recorded in the HDD 104 is erasable and the one recorded first (the oldest) is scheduled to be erased. The message data and the e-mail address preset as the notification destination address on the reserved program setting screen described above corresponding to the program to be deleted are supplied to the communication control unit 113, and the message data is transmitted to the e-mail address. Command.

  Based on a command from the control unit 105, the communication control unit 113 transmits the message data supplied from the control unit 105 to the mail address supplied from the control unit 105 via a network such as the Internet.

  As shown in FIG. 8, in this example, the program deletion schedule notification e-mail is the sender's e-mail address “XXXXXX” and the subject “program deletion schedule notification”. And the main text “Erase of BS news program will be implemented on 2005/02/08 (Tue)”.

  Thereafter, erasure of the erasable program is executed under the control of the control unit 105. At that time, it is possible to delete the data in descending order of importance. In this case, “BS news” is deleted.

  Thereafter, in step S9, the HDD recorder 100 transmits a program deletion execution notification mail as shown in FIG. That is, the control unit 105 generates message data indicating that the erasable program is deleted, supplies the generated message data and a preset mail address to the communication control unit 113, and the message data is sent to the mail address. Command to send to.

  Based on a command from the control unit 105, the communication control unit 113 transmits the message data supplied from the control unit 105 to the mail address supplied from the control unit 105 via a network such as the Internet.

  As shown in FIG. 9, in this example, the program deletion execution notification email is the sender's email address “XXXXXX” and the subject “program deletion execution notification ”And the text“ Broadcasting of BS news program was executed on 2005/02/08 (Tue) ”. Then, it returns to step S1 and the process after step S1 is repeatedly performed.

  In step S10, the control unit 105 determines whether there is a program that can be rate-converted among the recorded programs, that is, there is a program that can be recompressed at a compression rate lower than that at the time of recording. It is determined whether or not. In the reserved program setting screen described above, a program having the setting item “recompression” set to “2 (compressible)” can be recompressed at the recompression rate set in the setting item “recompression rate”. is there. By reducing the compression rate, the free capacity of the HDD 104 can be increased.

  As a result, if it is determined that there is no program that can be recompressed at a compression rate lower than that at the time of recording among the recorded programs, the process proceeds to step S13. On the other hand, when it is determined that there is a program that can be recompressed at a compression rate lower than that at the time of recording among the recorded programs, the HDD recorder 100 sends a program recompression schedule notification mail as shown in FIG. Send.

  In other words, the control unit 105 generates message data indicating that the program recorded in the HDD 104 can be recompressed and the program recorded first (the oldest program) is to be recompressed. The message data and the mail address preset as the notification destination address on the reserved program setting screen described above corresponding to the program to be recompressed are supplied to the communication control unit 113, and the message data is addressed to the mail address. Command to send.

  Based on a command from the control unit 105, the communication control unit 113 transmits the message data supplied from the control unit 105 to the mail address supplied from the control unit 105 via a network such as the Internet.

  As shown in FIG. 10, in this example, the program recompression schedule notification e-mail is the sender's e-mail address “XXXXXX” and the subject “program recompression schedule notification "And the text" The world will look like it on 2005/02/08 (Tuesday)! The program will be recompressed by the TV Special Search Department. " Then, it progresses to step S11.

  In step S11, the control unit 105 reads out the video / audio data of the program that can be recompressed at a compression rate lower than that at the time of recording from the recorded programs, supplies the video / audio data to the MPEG compression unit 102, and sets in advance. Command to recompress at a lower recompression rate than during recording.

  The MPEG compression unit 102 recompresses the video / audio data supplied from the control unit 105 at an instructed recompression rate, and supplies the recompressed video / audio data to the writing unit 103. The writing unit 103 records the recompressed video / audio data supplied from the MPEG compression unit 102 in the HDD 104.

  Next, in step S12, the HDD recorder 100 transmits a program recompression execution notification mail as shown in FIG. In other words, the control unit 105 generates message data indicating recompression, supplies the generated message data to the communication control unit 113, and sets a notification destination address set corresponding to the recompressed program. The data is read from the data storage unit 110, supplied to the communication control unit 113, and commanded to transmit the message data to the notification destination address.

  The communication control unit 113 transmits the text data supplied from the control unit 105 to the notification destination address via a network such as the Internet.

  As shown in FIG. 11, in this example, the program recompression execution notification e-mail is the sender's e-mail address “XXXXXX” and the subject “program recompression execution completion notification”. No. "and the main text" The world is visible on 2005/02/08 (Tuesday)! The TV special search department program has been recompressed. " Then, it returns to step S1 and the process after step S1 is repeatedly performed.

  If it is determined in step S10 that there is no program that can be recompressed at a compression rate lower than that at the time of recording in the recorded programs, the process proceeds to step S13. In step S13, the HDD recorder 100 transmits a remaining capacity shortage warning notification mail as shown in FIG.

  That is, the control unit 105 displays message data indicating that the remaining capacity of the HDD 104 is less than the reference value (the remaining capacity is insufficient), and that there is no erasable program and no rate convertible program by recompression. Communication control of the message data generated and the notification destination address to which the message data is to be notified when the remaining capacity of the HDD 104 is less than the reference value and there is no erasable program or re-compressible program The message is supplied to the unit 113, and the message data is instructed to be transmitted to the notification destination address.

  The notification destination address when the remaining capacity of the HDD 104 is less than the reference value and there is no erasable program or re-compressible program is “1 (Protected) in the setting item“ Re-compression ”on the reserved program setting screen. ) ”May be set as the notification destination address set in the setting item“ notification destination address ”of the reserved program, or there is no erasable program or recompressible program. The notification destination address in this case may be set separately.

  As shown in FIG. 12, in this example, the remaining capacity shortage warning notification e-mail is the sender's e-mail address “XXXXXX” and the subject “Insufficient remaining capacity warning notification”. ”And the main text“ The remaining HDD capacity is less than XXGB. Scheduled recording is not possible as it is. Please organize the data manually. ”.

  When the process in step S13 ends, the process returns to step S1, and the processes after step S1 are repeatedly executed. In this way, until the remaining capacity value of the HDD 104 becomes equal to or greater than the reference value, the program recorded in the HDD 104 is erased or recompressed, and processing is performed to increase the remaining capacity.

  FIG. 13 shows an example of a recorded program list screen that displays a list of recorded programs. FIG. 13A shows a recorded program list screen when the remaining capacity of the HDD 104 is less than a predetermined reference value as a result of recording a reserved program or the like. In this example, the remaining capacity of the HDD 104 is 10 gigabytes (GB).

  Since the value of the remaining capacity of the HDD 104 is less than the reference value (30 GB in this example), the program that has been recorded until the value of the remaining capacity of the HDD 104 becomes equal to or greater than the reference value according to the procedure described above with reference to the flowchart of FIG. Is erased and recompressed.

  FIG. 13B shows an example of a recorded program list screen when the remaining capacity value of the HDD 104 is equal to or greater than the reference value. Of the programs on the recorded program list screen shown in FIG. 3, NO. Each of the eight programs is erased and NO. 2, NO. Each of the five programs is recompressed.

  NO. The program 2 is recompressed according to the recompression rate “SP” preset in the setting item “recompression rate”, and the image quality is changed from “XP” to “SP”. Then, “1 (protection)” is automatically set in the setting item “recompression”, and further recompression cannot be performed.

  NO. The program No. 5 is recompressed according to the recompression rate “4.8” preset in the setting item “recompression rate” by recompression, and the image quality is changed from “9.2” to “4.8”. has been edited. Then, “1 (protection)” is automatically set in the setting item “recompression”, and further recompression cannot be performed.

  As described above, when the remaining capacity value of the HDD 104 is less than the predetermined reference value, the recorded programs are deleted and recompressed in order of decreasing importance before a new program is recorded. The remaining capacity of the HDD 104 is increased until the reference value is exceeded.

  In the above embodiment, among the already recorded programs, the recompressible programs are recompressed to convert the compression rate and the remaining capacity of the HDD 104 is increased. When recompression is possible, it is also possible to record by compressing at a recompression rate set at the time of recording.

  In the above embodiment, deletion and recompression are performed in order from the lowest importance. However, if the importance is the same, the program recorded earlier (the recorded date is the oldest) is important. Depending on the degree, it can be erased or recompressed.
