Each is provided.

  As shown in FIG. 2, the automatic recording setting management unit 25 sets a condition for narrowing down programs and a condition for recording narrowed programs when the user sets automatic recording. A screen example G1 of “automatic recording setting” to be displayed is displayed.

  The condition setting means 25a is a selection element for narrowing down the program by the screen example G1, for example, “keyword”, “broadcast time zone”, “broadcast channel”, “rebroadcast type”, “genre”, and other various elements. The condition can be set from

  The program narrowing means 25b designates “keywords” limited to a specific team game as a selection element from the programs related to, for example, a soccer game set by the condition setting means 25a, and executes narrowing of programs. Can do. Specifically, the maximum recording time per day (0/1/3/6 hours), recording priority, recording quality, recording destination folder, etc. can be specified as other recording conditions. The user can set an arbitrary number (for example, 12) of such automatic recording settings.

As for “keyword”, AND search, OR search, and NOT search can be arbitrarily selected and set. For example, as shown in a screen example G1 in FIG. 2, “L'arc en ciel” or “L'arc en ciel” is included and “Larc” is not included. Can be specified.
The “broadcast time zone” can be specified as “17:00 to 23:00”. The “broadcast channel” can be specified as “031 CCNS channel”.
The “rebroadcast type” can be specified as “include”.
The “genre” can be designated as “01 domestic rock / pop”.

  The recording condition setting means 25c has a function of setting conditions for automatic recording from programs that match the narrowing conditions by the program narrowing means 25b. For example, as shown in FIG. 2, the automatic recording can be set to 120 minutes. Also, it can be set to follow the program and record. Furthermore, it has a function of automatically deleting when the capacity of the recording apparatus M is insufficient.

  The recording reservation unit 25d has a function of automatically recording recording of the programs narrowed down by the program narrowing unit 25b according to the condition setting.

  The viewing rate calculation unit 26 determines the viewing rate according to the number of programs automatically recorded by the recording unit M and the number of times the user has viewed the automatically recorded program. Viewing digestion rate calculating means 26a for calculating X (see FIG. 3) is provided.

  FIG. 3 is a graph showing an example of a daily change situation of the audience consumption rate of the automatic recording setting.

  As shown in FIG. 3, the audience digest rate calculating means 26a, for example, the number of recordings x1, the number of viewings x2, the number of recent recordings x3 in the month from February 1, 2007 to February 28, 2007, The number of viewers x4 is counted, and the audience consumption rate X based on these data is calculated.

The number of recordings x1 is the number of recordings per day in a certain automatic recording setting.
The number of views x2 is the number of views per day in a certain automatic recording setting, like the number of recordings x1.
The recent number of recordings x3 is a moving average of the number of recordings x1, for example, for the past seven days.
The recent viewing number x4 is, for example, the moving average of the viewing number x2 over the past seven days, like the recent recording number x3.
The audience consumption rate X is obtained, for example, by dividing the recent viewing number x4 by the recent recording number x3.

  Then, using these data, as shown in FIG. 4, as the “automatic automatic recording setting list”, for example, six out of twelve automatic recording settings are displayed as a list. Yes.

  FIG. 4 is a diagram showing a list display screen example G2 of automatic recording settings in the recording / reproducing apparatus 10. In the screen example G2 shown in FIG. 4, the calculated audience digest rate X is displayed as a numerical value in the list of automatic recording settings together with the set narrowing conditions and the overview of the recording conditions.

  In the list display screen example G2 shown in FIG. 4, the automatic recording settings are arranged and displayed in the order of setting numbers. However, they can be arranged and displayed in the order of viewing rate X according to the user's operation. Also, the display may be displayed as pictographs (icons) according to the size of the audience digestibility X. Specifically, when the audience rating X is 0 to 1, if the audience rating X is 0 to 0.3, one crown icon is used, and if 0.3 to 0.6, the crown icon is used. If there are two, 0.6 to 1.0, three crown icons can be displayed. Furthermore, the background color of each automatic recording setting list may be determined according to the size of the viewing rate X, even if it is not a numerical value or an icon.

  FIG. 5 is a diagram showing a recorded program list display screen example G3 in the recording / reproducing apparatus 10. As shown in FIG. In this screen example G3, recorded programs by automatic recording are displayed together in a vertical group for each automatic recording setting. Each automatic recording group is arranged from the left in the order of audience rating. For example, the programs 5a and 5b are arranged in the order of recording in the column of the automatic recording setting 5 from the top. This can be displayed by switching between descending order and ascending order according to the user's operation. On the other hand, in the rows, the automatic recording setting numbers 5, 7,...

  Further, the audience digestion rate calculation unit 26 can display a caution screen as shown in FIG.

  FIG. 6 is a diagram showing an example of a caution screen G4 for the user when there is an automatic recording setting in which the audience viewing rate X in the recording / reproducing apparatus 10 is lower than the threshold value.

  The screen example G4 shown in FIG. 6 is an example in which a warning screen for the user is displayed when there is an automatic recording setting in which the audience digestion rate X falls below a predetermined threshold. As a condition for displaying the caution screen, for example, “there is an automatic recording setting where the audience viewing rate X is less than 0.1” and “10 days or more have passed since the previous caution screen was displayed”. And so on. When “Yes” is selected by the user operation while the caution screen is displayed, the screen shifts to the automatic recording setting list display screen of FIG. 4, and the cursor is focused on the automatic recording setting with the lowest viewing rate X. State. When the caution screen is displayed, if “No” is selected by the user operation, the caution screen is deleted.

  FIG. 7 is a diagram illustrating an example of a screen that displays that the automatic recording setting has been canceled when there is an automatic recording setting in which the audience viewing rate X is lower than the threshold value in the recording / reproducing apparatus 10.

  The conditions for automatic cancellation are, for example, “below 0.1 of the automatic recording setting” and “the user's prior approval on the initial setting screen”.

  Similarly, FIG. 8 is an example in which a caution screen G6 for the user is displayed. FIG. 8 is a diagram showing an example of a screen that displays that the automatic recording setting has been changed when there is an automatic recording setting in which the audience viewing rate X is lower than the threshold in the recording / reproducing apparatus 10.

  As conditions for the automatic change, for example, “below 0.1 of the automatic recording setting” and “the user's prior approval on the initial setting screen is the same as the example in which the user's attention screen G5 is displayed in FIG. Something ". In addition to reducing the maximum recording time per day, the automatic change content can reduce the maximum number of recordings per day. Further, it may be a requirement to lower the recording priority.

  As shown in FIG. 3, the audience rating rate X is calculated by calculating the number of recordings x1, the number of viewings x2, the number of recent recordings x3, the number of recent viewings x4, and the audience rating rate X based on these data. It has become so.

  The graph of FIG. 3 shows data calculated by the audience viewing rate calculation unit 26 and is not displayed every time the monitor 29 is displayed, but may be displayed on the monitor 29.

The audience viewing rate X shown in FIG. 3 is defined as, for example, [Formula 1] below.
[Formula 1]
Viewing rate X = recent viewing number (s, d) / recent recording number (s, d)
However, s: automatic recording setting number (1-12)
d: Date
Recent views: Moving average of views over the past n (= 7) days
Number of recent recordings: Moving average of recordings over the past n (= 7) days

  As shown in FIG. 3, the number of recordings and the number of views per day are indicated by, for example, blue and oil-colored bar graphs, and the moving average for each of the seven days is set as “recently recorded numbers” and “recently viewed numbers”. Shown in light blue line graph. A value obtained by dividing “recently viewed” by “recently recorded” is represented as “viewing rate X”, for example, in a purple line graph. In addition to the above definition, an overall audience consumption rate that does not depend on individual automatic recording settings may be calculated separately and normalized with this value.

  As described above, the contents to be notified to the user in the execution result of the computer block 13 are displayed on the display unit 28 of the recording / reproducing apparatus 10 or displayed on the monitor display 29 as OSD (on Screen Display). The

  The computer block 13 also has a key operation input unit 30 that provides an operation signal for operating the recording / reproducing apparatus 10. The key operation input unit 30 corresponds to, for example, operation switches and a remote controller (not shown) provided on the main body of the recording / reproducing apparatus 10. Further, it may be a PC (Personal Computer) connected to the recording / reproducing apparatus 10 using a communication means such as wired communication or wireless communication (such as optical communication or infrared communication). In any form, when the user operates the key operation input unit 30, the recording process of the input video / audio signal, the playback process of the recorded content, the editing process for the recorded content, etc. Can be applied.

  Note that the timing at which the computer block 13 controls the disk drive unit m2, the HDD unit m3, the data processor unit m4, the encoder unit 11 and / or the decoder unit 12, etc. is based on time data from an STC (System Time Clock) 31. Can be executed based on. Recording and playback operations are normally executed in synchronization with the time lock from the STC 31, but other processing may be executed at a timing independent of the STC 31.

  The decoder unit 12 separates and extracts each pack from a DVD format signal having a pack structure, a memory used when pack separation or other signal processing is performed, and main video data (video pack contents) separated by the separator. ), V (Video) decoder for decoding, SP (Sub Picture) decoder for decoding sub-picture data (sub-picture pack contents) separated by a separator, and audio data (audio pack contents) separated by a separator And an A (Audio) decoder for decoding.

  In addition, a video processor is provided that appropriately synthesizes the decoded sub-video with the decoded main video, and outputs a menu, a highlight button, subtitles, and other sub-videos superimposed on the main video.

  The output video signal of the decoder unit 12 is input to the video mixing unit 32. In the video mixing unit 32, for example, text data is synthesized. The video mixing unit 32 is also connected to a line that directly takes in signals from the TV tuner unit and the A / V input unit 16.

  A frame memory unit 33 used as a buffer is connected to the video mixing unit 32. When the output of the video mixing unit 32 is an analog output, it is output to the outside via an I / F (Inter Face) 34, and when it is a digital output, it is output to the outside via a first digital-analog converter 35. .

  The output audio signal of the decoder unit 12 is converted into an analog signal by the second digital / analog (D / A) converter 37 via the audio selector 36 and output to the outside. The audio selector 36 is controlled by a select signal from the computer block 13. Thus, the audio selector 36 can directly select an audio signal that has passed through the encoder unit 11 when directly monitoring a digital signal from the TV tuner unit or the A / V input unit 16.

  The formatter 14 of the encoder unit 11 creates segmentation information during recording and periodically sends it to the MPU of the computer block 13 [information at the time of GOP (Group of Picture) head interrupt, etc.].

  The segmentation information includes the number of VOBU (Video object Unit) packs, the end address of an I (Intra) picture from the beginning of the VOBU, the playback time of the VOBU, and the like.

  At the same time, information from an aspect information processing unit (not shown) is sent to the MPU at the start of recording, and the MPU creates VOB (Video object) stream information (STI; Stream Information). Here, as stream information, resolution data, aspect data, and the like are stored, and at the time of reproduction, each decoder unit is initialized based on this information.

  In the recording / reproducing apparatus 10, one video file is recorded on a DVD. Further, in order to continue playback without interruption while accessing (seeking) data, a minimum continuous information unit (size) is determined. This unit is called a CDA (Contiguous Data Area). The CDA size is a multiple of an ECC (Error Correcting Code) block (16 selectors), and recording is performed in units of CDA in the file system.

  The data processor unit m4 receives data in VOBU units from the formatter 14 of the encoder unit 11, and supplies data in CDA units to the disk drive unit m2 or the HDD unit m3.

  Further, the MPU of the microcomputer block 13 creates management information necessary for reproducing the recorded data. When the MPU recognizes a data recording end command, it sends the created management information to the data processor unit m4.

  Thereby, the management information is recorded on the optical disk m1 or the hard disk. For this reason, when encoding is performed, the MPU of the computer block 13 receives data unit information (such as segmentation information) from the encoder unit 11.

  Further, the MPU of the computer block 13 recognizes the management information (file system) read from the optical disk m1 and the hard disk at the start of recording, recognizes the unrecorded area of each disk, and thereby transmits data via the data processor unit m4. Recording area is set to disc.

  Next, a recording / reproducing method in the recording / reproducing apparatus of the present invention will be described with reference to FIG.

  FIG. 9 is a flowchart showing steps for carrying out the recording / reproducing method of the present invention.

  A step of performing the recording / reproducing method after the recording / reproducing apparatus 10 is in an operating state will be described.

A condition for narrowing down the program that the user is interested in from the program table is set. That is,
Conditions are set from various factors such as “keyword”, “broadcast time zone”, “broadcast channel”, “rebroadcast type”, “genre”, and other elements for narrowing down programs by the screen example G1. For “keyword”, AND search, OR search, and NOT search are arbitrarily selected and set <step 1 (st1)>.

  Then, automatic recording conditions are set in accordance with the narrowing-down conditions of <Step 1 (st1)>. That is, the maximum recording time per day (0/1/3/6 hours), recording priority, recording quality, recording destination folder, etc. are designated <Step 2 (st2)>.

  Subsequently, if the element set in <Step 1 (st1)> is a soccer game, the game is limited to a specific team game related to the program, for example, "keyword" is specified, and the program is narrowed down from the program table. <Step 3 (st3)>.

  Next, recording reservation is made for the narrowed programs in accordance with the automatic recording conditions set in <Step 3 (st3)> <Step 4 (st4)>.

  Then, the program reserved for recording in <Step 4 (st4)> is recorded (automatically recorded in the recording device M) <Step 5 (st5)>.

  Subsequently, the viewing rate is calculated according to the number of programs automatically recorded in <Step 5 (st5)> and the number of times the user has viewed the automatically recorded program (viewing rate calculation unit 26). <Step 6 (st6)>.

  By performing the above <Step 1 (st1)> to <Step 6 (st6)>, the automatic recording setting that is considered unnecessary on the user side is specified, and the user is notified and the automatic recording setting is changed or canceled. It is possible to avoid unnecessary recording by prompting or automatically lowering the recording priority.

  According to the embodiment of the recording / reproducing apparatus 10 of the present invention, the automatic recording setting management unit 25 and the audience rating calculation unit 26 are collectively provided in the microcomputer block 13, but are not necessarily provided in the microcomputer block 13. It is not necessary, and it may be incorporated in an arithmetic device having another computer function. A computer dedicated to the recording / reproducing apparatus 10 may be provided.

  Furthermore, according to the embodiment of the recording / reproducing apparatus 10, several kinds of recording apparatuses M are provided, various tuners 17a to 17d are provided as tuners, and further, components such as the encoder unit 11 and the decoder unit 12 are provided. However, it is not always necessary to provide all of them.

  In particular, with the recent digitalization of broadcast waves and the advent of digital-compatible receivers, the encoder unit 11, the decoder unit 12, the first digital-analog converter 35, and the second digital-analog (D / A) conversion There is a tendency for devices such as the vessel 37 to be no longer necessary.

  Therefore, when the recording / reproducing apparatus 10 is applied to a receiver, it is needless to say that the recording / reproducing apparatus 10 may be configured by equipment necessary to exert its function in the entire configuration of the receiver.
