- the "B Corner” publishes Chinese food recipes
- the "C Corner” publishes Indian food recipes.
- food-related sponsor CMs are broadcast on CM1 and CM2
- magazine-related sponsor CMs are broadcast on CM3.
- CM identifier is configured in CM units such as “CM1”, “CM2”, and “CM3”. Detailed information is added to each CM, which includes the CM sponsor's name and CM data such as linked product names are indexed. As shown in Fig. 3 (b), it shall be [ ⁇ X confectionery 100 chocolate], [ ⁇ X X shop-X ⁇ ⁇ senbe, etc.].
- the time index is an index indicating which program and corner are located at which position in this endless video. ing.
- FIG. 4 (FIG. 4)
- the mechanism for distributing the time index to which the identifier is added to the digital recording and reproducing apparatus 10 is performed as follows.
- a time index corresponding to program data for distribution is uploaded to the time index server 50 on the Internet.
- the digital recording and reproducing apparatus 10 is connected to the time index server 50 via the network controller 26 and periodically asks whether the latest time index is present or not.
- the time index is downloaded (time index receiving means), and the downloaded time index is stored in the HDD 17 (time index recording means).
- the reproduction signal is transmitted to the CPU 23
- the HDD control unit 18 detects an identifier corresponding to the reproduction signal, and extracts program data associated with the detected identifier from the HDD 17. That is, by selecting the downloaded time index, the user can view and listen to detailed program data such as the corner unit in the program and CM information in addition to the program unit. Therefore, high-speed cueing of program data and program corner data becomes possible, and a viewer can quickly find the target program. In addition, there is no need to perform editing and other work in the corners of programs that you want to store for a long time.
- the time index enables transmission and reception between a plurality of users, and can recommend its own recommended program, program corner data, etc. to other users. It sends its recommended program corner data and its time index from the network controller 26 to the time index server 50, and it is efficient for other users to use it! / ⁇ Enable program viewing.
- a bit rate change shelf function is adopted for recording program data. It is determined whether program data for eight days of all channels (8 tuners) can be recorded constantly on the HDD 17a, and if it is determined that recording is possible, recording is performed at a preset compression rate for all programs. If it is determined that recording is not possible, the function is to change and record the compression rate of program data to be recorded for each program genre.
- the bit rate conversion function is mainly processed by the HDD control unit 18.
- program genre refers to various program genres such as sports, drama, news, variety and movies.
- the standard of the compression rate is set as follows. News and variety etc. has relatively little movement, so even with a high compression rate, there will be almost no trouble with viewing. On the other hand, sports and movies, etc., have been set to a low compression rate because they are often moving sharply. Also, dramas and the like are in the middle setting of these.
- the program genre sorting means sorts program data into a plurality of genres in advance (S101).
- the program data sorted by the compression rate setting means is set to a compression rate different for each program genre (S102).
- the program genre in which the program category genre Z compression rate recording means is classified is associated with the compression rate set by the compression rate setting means and recorded in the program genre database (S 103).
- the program genre discrimination means discriminates whether or not a plurality of program data newly received by the program data reception means (S104) falls under the program genre of the program genre database (S105) o Program data is a program If it exists in the genre database, the program data compression means compresses the program data at the compression rate of the corresponding program genre (S106).
- the program data compression means can also compress at a compression rate that approximates the program genre when it is determined that the program data does not exist in the program genre database (S 107). This corresponds to the case where program data of a new genre is received. It is suitable when the received program data does not exist in the program genre database or when the program genre can not be set in detail. For example, approximate compression may be used for the genre "other".
- the free space determining unit determines whether or not the program genre of the program genre database falls under the program data. If a program genre exists in the program genre database, it has a function to compress at the compression rate of the corresponding program genre.
- the compression rate power set by the compression ratio setting means is also changed to a compression rate that can be stored in the capacity that can be recorded within the total capacity of the HDD 17. It is realized by means.
- the total capacity calculated by the recording capacity determination means It is determined whether or not recording is possible within the total capacity of the recording means (S202). If it is determined that the total capacity has been exceeded, the compression rate changing means changes the compression rate set by the compression rate setting means to a compression rate that fits within the total capacity of the recording means (S203). .
- priority is given to those of high image quality (low compression). Even if the image quality is low, the compression rate may be reduced by% of the over capacity uniformly. Therefore, regardless of the total capacity of the recording means, 8 days worth of program data can be recorded surely.
- the program data will be automatically deleted from the old program data after 8 days.
- the program data will be automatically deleted from the old program data after 8 days.
- the deletion of the yarn thread data does not have to be synchronized with the reception timing of the time data, and can be changed by setting.
- eight days is used because there are many programs that are being broadcasted with one week apart. This can be extended by changing settings or adding HDD.
- eight days' worth of program data is constantly recorded, it will be possible to cope with various situations. For example, even if you forgot to watch last week's program data, you can cope with it by continuing watching from last week when watching this week's program data.
- the program data compressed and recorded in the always-recording HDD 17a is changed as follows according to the storage period and the like of the storage expiration warning means.
- the thumbnail of the program data is changed from color display to black-and-white gradation display.
- the font displaying the program name becomes old and collapses into a font. Also, it is possible to distinguish from other program data at a glance. Therefore, it is possible to easily identify program data desired to be stored from a large number of program data recorded by continuous recording in accordance with a change in time, which can enhance the convenience of the user.
- the digital recording and reproducing apparatus 10 is provided with no signal detection means.
- This is a tuner 12 It is a function to make the HDD 17 stop the recording of the program data when it is detected that the video signal transmitted from the is not received.

- the recording means comprises an identification ID database in which identification IDs for identifying a plurality of users are recorded, and the receiving means comprises an identification ID transmitted from an individual button provided on the remote controller. And an identification ID determination unit that determines whether the identification ID is a set identification ID or not. In addition, if the identification ID is already set according to the discrimination by the identification ID discrimination means, it is discriminated whether or not the top menu of the user related to the identification ID is displayed, and the top menu is displayed. And a top menu display means for displaying the top menu on the output device if not.
- an individual menu screen is created for each user, and an “individual button” is assigned to the menu screen. Then, for example, as an example of the viewing frequency, the user 1 often views the power of watching television programs of many genres, particularly the educational television. User 2 often views news and sports programs mainly. The user 3 views a large number of dramas and varieties. The user 4 obtains reproduced program data such as ⁇ , which is completely considered except for a movie.
- the network controller 26 accesses a server on the Internet to transmit data, and the server analyzes the viewing information of the acquired program data for each user. Then, preference information program data for each individual is created, transmitted to the digital recording and reproducing apparatus 10, and displayed on the menu screen of each user.
- the menu screen can also be created by the user periodically viewing and frequently-watching threading data registered in his own menu screen. The created menu screen can be displayed in one shot by pressing the "personal button".
- the identification ID setting unit sets the identification ID in the "individual button” (S301). For example, when used by four families, it will be assigned to each of the four "personal buttons.”
- the identification ID storage means stores the identification ID assigned to the "individual button” together with the button code in the identification ID database (S302).
- the signal receiving unit 25 receives the identification ID (S303).
- the identification ID determining means determines whether the received identification ID is a set identification ID or not with reference to the identification ID database (S304). If not set, the setting screen for identification ID is displayed. If it has been set, it is determined whether the top menu of the user relating to the identification ID is displayed (S305). If the top menu is displayed, the process ends, and if the top menu is not displayed, the top menu is displayed (S306).
- a general digital recording and reproducing apparatus (general apparatus) is structured hierarchically from the top menu on which various menus are displayed when performing an operation relating to recording and reproduction.
- top menu display ⁇ playback menu display ⁇ program selection In order to play back a program on a general-purpose device (conventional recording and reproduction device), a procedure of “top menu display ⁇ playback menu display ⁇ program selection” is required.
- a general unit is shared by a plurality of users such as a family, all playable program data recorded by a plurality of users is displayed when the play menu is displayed. It is cumbersome to select related program data.
- one step is added as "top menu display ⁇ playback menu display ⁇ individual menu display ⁇ program selection".
- the convenience of the digital recording and reproducing apparatus is improved.
- a television recording device shared by the family it is possible to dramatically improve the convenience when using a digital recording and reproducing device by a plurality of users.

- the day of the week determination menu is a time selection menu that allows you to select the time from 1 to 24 o'clock by pull-down or scroll format, a day of the week from Sunday to Saturday can be selected by pull-down or scroll format, and This button is selected when the time and day of the week are determined, and the decision button has a function as a program data reproduction signal.
- the remote controller or the input unit 28 selects a predetermined time from the time selection menu, selects the predetermined day of the week selection menu, and selects the decision button, the time of day selection signal receiving means receives the time of day selection signal. Then, program data corresponding to the time-of-the-week selection signal is extracted from the constantly recorded HDD 17a and reproduced. That is, it is possible to reproduce target program data at high speed by setting the time and day of the week in the time-of-day determination menu displayed on the top menu 1 screen.
- the remote controller or the input unit 28 stores the program data storage menu.
- the program data storage signal receiving means receives a program data storage signal.
- the program data corresponding to the received program data storage signal is recorded in the storage HDD 17 b separate from the constantly recorded HDD 17 a. That is, if the program data storage menu is selected for the program data which is particularly desired to be kept, it can be stored in the storage HDD 17b.
- the program data storage menu may be provided with various setting items such as a compression rate.
- the recommendation menu is a function that enables another user to view programs recommended by the user and can be viewed by another user.
- the recommendation number signal receiving unit It receives a recommended program signal including data such as a program ID, program title, and broadcast date and time that specify program data. Then, the received recommended program signal is transmitted to other users via the network. Selecting the recommendation menu allows you to send recommended programs to other users. At this time, since data such as a program ID specifying a program, a program title, and a broadcast date and time are sent together, the digital recording device related to the other user who has received it reproduces the corresponding program data. Using this function makes it unnecessary to lend and borrow video data between friends, etc., and improves the convenience of the user.
- the digital recording and reproducing apparatus 10 has a next program function and a previous program function. This is an access for the signal reception unit 25 to move in units of program data and program corner data transmitted from the next program button of the remote controller or the previous program button cover during reproduction of program data.
- Program database search that searches the database power of programs that receive a signal, and that the time index broadcast start time is earlier or later than the program currently being played, in time later or earlier and in the same channel program than the program currently being played Means. If there is a valid program as a search result, the program data being played back is stopped, and program data judged to be valid as a search result after the program data being played back is stopped is switched to the menu screen etc. Do not play, but play control procedure.
- FIG. 7 (FIG. 7)
- Figure 7 shows the procedure.
- Each program data has a time index identifier.
- the program data can be sorted on the basis of predetermined data set by the user, such as the time axis or the order of topicality.
- the signal reception unit 25 receives the access signal (from the S40 Do signal reception unit 25, the CPU 23 and the HDD control unit 18 detect program data,
- the detected program data is decoded by the MPEG decoder 20 via the demultiplexer 19 (S402).
- the valid time index is the state where the program is recorded next when the “next program button” is pressed. That is, there is no program data at the boundary between the recorded program data and the program data being broadcasted in real time, so even if the "next program button” is pressed, it is recorded! I can not do it. In this case, it is determined that there is no valid time index, and an error display is output to select the last watched program ⁇ Return to the menu immediately before the playback (S406).
- FIG. 8 (FIG. 8)
- FIG. 8 is a conceptual diagram conceptually showing the transition of program data when the next program button is pressed. As shown in the figure, an animation program broadcast from 19:00 is currently being viewed.
- the animation program recorded at 19:00 to 20:00 is moved to drama 1 recorded at 20:00 to 21:00. This movement is performed in units of program data such as animation and drama 1 and in units of corners, and is reproduced without moving to a menu screen for selecting program data.
- each program data is associated with a time index identifier, it will be reproduced along with this time index identifier. That is, in the case of the animation program at 1 9:00, pressing the “next program button” twice will play the drama 2 at 21:00 to 22:00.
- the "previous program” function can be displayed on the TV by pressing the "previous program” button on the remote control. While the program data is displayed, the program data recorded at a time earlier than the program data currently being reproduced is reproduced. As shown in Figure 9, when you watch the broadcast program broadcasted from 19:00, and the user presses the "previous program” button, the animation program recorded at 19: 00-20: 00 is displayed. It will move to the news recorded at 18:00 to 19:00.
- the desired program data is listed from the recorded program data from the TV screen on which the program data is displayed and displayed. Need to switch to the screen. Then, desired program data is selected, and it is supposed to return to the TV screen again. Once selected, even if you want to see other program data, you need to move to the menu screen hierarchy again. In other words, frequent screen switching occurred, which was annoying.
- the screen is switched by the operation of one button, and movement of program data units is easily realized, which is highly convenient for the user.
- the channel switching function in the past is as follows. That is, during reproduction of program data, when the signal reception unit 25 receives an access signal for moving in program data units and program corner data units to which the channel switching button power at the past time point of the remote controller is also transmitted,
- the database search means searches the database for different programs broadcasted on other channels on the same day of the same day as the broadcast date and time of the program currently being played. If a valid program exists as a search result, the program data stopping means stops the program data being reproduced. Further, the program data reproduction means reproduces the program data judged as valid as the search result after the program data being reproduced is stopped, without switching the screen such as returning to the menu screen at one end.
- the digital recording and reproducing apparatus 10 has a ranking moving function. That is, the output device when the receiving means receives an access signal transmitted using a ranking 'list storage means storing the ranking / list in advance and the next program button or the previous program button of the remote controller.

- the control means reproduces the program data.
- Ranking means, for example, a ranking created based on the topicality order of a program, or a blog on the Internet, and the search results are aggregated and reflected as a program ranking. and so on.
- pressing the next program button or the previous program button returns to the ranking selection screen again, eliminating the need to reselect a program, Based on the same program data ranking selected earlier, it is now possible to start the reproduction of the program ranked next to the program or the program preceding the ranking.
- identifiers of a plurality of time indexes are associated with one program data, it is possible to select a plurality of desired corners in the program data.
- a plurality of desired corners in the program data For example, when trying to see today's recordings of Grand Sumo, we will select only the efforts of Yokozuna A, Ozeki B and Kogyu C. Then, if it is assumed that Kogyu C's work is done first, if the "next program” button is pressed before the playback is over, it jumps to Ozeki B's work and if the "next program” button is pressed, Yokozuna A's We can see approach. Of course, after making multiple selections, if you enter viewing and do not press any button, the three efforts of Kokoni C, Ozeki B, Yokozuna A will be reproduced continuously.
- the digital recording and reproducing apparatus 10 has a quick view function.
- the fast-view function is a time index server 50 that creates a time index of the corners and scenes in the program to view the program's digest version, and receives this time index to make it possible for the digital recording and reproducing device at hand. Since you can watch a program from certain program data by picking up only a program corner specified by the digest version time index or a predetermined scene, the user can spend time efficiently watching the program quickly. it can.
- the digital recording and reproducing apparatus 10 has a function of storing program data in addition to recording of program data. This means that the program data recorded by the digital recording and reproducing apparatus 10 is stored for eight days, but is automatically deleted thereafter. Therefore, the program data to be stored is stored in the storage HDD 17b. Program data is saved by the input unit 28 and the “program data save button” of the remote controller. The program data stored in the storage HDD 17b will not disappear unless a format or other format deletion command is issued.

- the digital recording / reproducing apparatus 10 automatically backs up the recording position of the program data, and overwrites and loses the program data recorded so far when recovery processing is performed after a power failure or failure. It has a feature to make sure there is no This is for troubles such as power failure and unintended shutdown, and in a state where program data is always recorded on the HDD 17a for continuous recording, the recording position data of the program data is periodically changed to another file. It is realized by recording in.
- the recording position data of the program data means that the recording position data grasping means constantly grasps the recording position of the program data to be recorded in the continuous recording HDD 17a by the ring buffer method. Then, after recovery from a power failure or the like, recording is resumed with reference to recording position data recorded in another file.
- the separate file for recording the recording position data is recorded in one or both of the constantly recording HDD 17a and the storage HDD 17b.
- the digital recording and reproducing apparatus 10 has a replacement function of rebroadcast program data! / ⁇ . This is the old before being rebroadcast based on the rebroadcast information added to the time index! This is realized by processing for retrieving program data and replacing it with rebroadcast program data. Therefore, programs rebroadcast within eight days will be stored for a further eight days, as the new broadcast will be recorded on the date of recording. Therefore, it is possible to extend the preservation period.
- the compression method of video data used by the MPEG encoder 14 and the MPEG decoder 20 may be either MPEG-2 or MPEG-4. Moreover, it is also possible to use other compression methods other than MPEG as a compression method of video data. For example, AVI, DivX, XVD, H.264, XVid, etc. may be used. (View Management Function)
- the digital recording and reproducing apparatus 10 is provided with a viewing management function capable of restricting the reproduction of the program corresponding to the set viewing restriction by the administrator setting the viewing restriction for the specific user.

- the total viewable time can be set by dividing it into daily, weekly and monthly units. For example, the total viewable time can be set to Z2 hours a day, Z14 hours a week, Z50 hours a month.
- the viewable time limit function allows parents to give their children a viewable time frame, which helps to prevent excessive viewing of TV. Then, if the "viewable total time” is exceeded, it will automatically become unviewable, so for example, it will not be necessary to check the child's viewing time even when the parent is out, thus improving management.
- the point setting function is a function for managing a program by points, and in order to view a program, "viewable points" are needed. Parents set the "viewable points" for their children in advance. That is, although the playable time limit function was limited by time, the point setting function is to limit viewing by point. For example, if you set a "viewable point" of 20 points for a child and the program point per program is 1 point, the ability of the child to view up to 20 programs can not be watched because of the restriction on viewing more than that. Become. It should be noted that the judgment as to whether the user has watched or not is counted when one minute or more is watched, and is not counted when one minute or less.
- the rating data setting restriction function is a function in which rating data representing the high and low of the rating is given to the program in advance, and the viewing restriction is performed according to the rating data. For example, suppose that the rating of the program is classified into three: pine, bamboo and plum (A, B, C). In this case, one viewable “viewable point” is required to view “rating pine (A)", and two “viewable points” to view “rating bamboo (B)” It is necessary, and 3 points of “viewable points” are required to view “rated plum (C)". In addition, "rated plum (C)
- the rating data to be assigned to the program is determined in advance by the program distribution server that manages the rating data.
- the program distribution server receives temporary data of rating that is used as a criterion by which program producers or sponsors, etc. have a positive or negative impact on children, and a "rating" is set based on the temporary data. You can also If rating data is set, children will not be able to view programs that require high points such as “rated plum (C)”.
- parents can use the rating data as a criterion for judging whether or not they should show children, thus facilitating parental control.
- the quiz function is a function that enables a program to be viewed only when the child answers the quiz given the question and the correct answer.
- This quiz for questions it is a problem that can be solved if you do homework of the school, and there are several quizzes for education according to the age (school grade) and ability of the children. Parents select quizzes according to their children and set how many questions they want to watch the program. As an answer method, multiple choice type (such as four choices) that can be easily selected by the remote control is desirable.
- a quiz content creator who produces and provides question quizzes may be configured to distribute systematically as an educational program in which each subject is systematically constructed. In this case, it can be expected to promote sales of teaching materials such as correspondence education provided separately by quiz content producers.
- the recommended program function is a function that enables children to view other programs by watching the "recommended programs" sent by their parents. For example, parents may want to show their children the program “The Great Universe Tour”. In this case, if "Kids of the Great Universe” is registered and set in the recommended program registration column for children, when the child activates the digital recording / reproducing device 10 by the "individual button”, "Diddens of the Great Universe” is displayed. A screen prompting you to watch is displayed. And, it is possible to select another program and watch it only when watching "Daily Space Tour". In this way, it is possible for the parents to show the program which they want to show to the child semi-forcefully, so that the digital recording and reproducing apparatus 10 can be used as a teaching aid.
