Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a broadcast signal recording apparatus for receiving and recording a broadcast signal, and more particularly to a broadcast signal recording apparatus and a broadcast signal recording method for displaying management information of received information corresponding to user identification information.
[0002]
[Prior art]
Recently, as a receiving device for receiving a program broadcast on terrestrial, satellite broadcasting, or cable, a receiving device has been developed that has a recording device such as a hard disk built in the receiving device so that the program can be stored once and reproduced. . JP-A-9-70020 and JP-A-11-127396 are disclosed as such broadcast signal recording apparatuses.
[0003]
The ISDB receiver disclosed in the above Japanese Patent Application Laid-Open No. 9-70020 receives a broadcast signal in which various types of information such as video, audio, and data are multiplexed, and stores a storage unit for storing the information, and a storage priority for the information. A storage unit for the general priority data indicating the general priority to be displayed, and a control unit for controlling them. Then, according to the priority set by the user, the stored information is sequentially deleted from the lowest priority.
[0004]
FIG. 13 shows an example of management information indicating the priority held by this receiving apparatus. According to this figure, a method for selecting information to be deleted when the capacity of the storage unit becomes full is described in this publication.
[0005]
As shown in FIG. 13, the recording units 1 to 3 are already stored in the storage unit, and the priority x and individual program priority y for each genre such as sports, historical drama, and drama are set. From the elapsed time t from the end of accumulation, the total priority P is P = ax + by-ct (a, b, c are coefficients)
It is assumed that it is obtained by the following formula. As a result of accumulating the contents of the three programs, it is assumed that the capacity of the accumulating unit is full. In this state, when the next program of the recording order 4 is to be stored, the program of the recording order 2 having the lowest overall priority P is deleted.
[0006]
Therefore, the larger the total priority value is, the longer the accumulated time is, and it is possible to accumulate only the data that suits the user's preference without increasing the capacity of the accumulation unit. It is automatically deleted without the user's knowledge.
[0007]
However, when the storage unit is full, only high priority programs are stored, and the difference in priority between the program to be deleted and the program that remains in the storage unit without being deleted is small. For this reason, there is a problem that the program genre and the priority of individual programs cannot reflect the subtle preference of the user, and a program that the user does not want to delete may be deleted sometime. In addition, the program that has been reproduced in the accumulated program data or the reproduced part of the program being reproduced is not preferentially deleted even though the possibility of re-reproduction is low. There is.
[0008]
On the other hand, in the latter Japanese Patent Application Laid-Open No. 11-127396, the storage unit for storing various data separated from the broadcast signal, and information indicating the storage priority and the deletion candidate for the stored data stored in the storage unit Storage unit, an input unit that receives an input operation from a user, and a control unit that controls these operations. At this time, the control unit selects the data having the lowest retention priority as a deletion candidate when the free space in the storage unit becomes a certain value or less, writes information indicating the deletion candidate in the storage unit, and confirms that the data is a deletion candidate. By displaying the monitor screen and providing a function to delete this data from the storage unit after a certain period of time, it is possible to trick the user into unnecessary data with low priority while reflecting the user's preference by showing the deletion candidate to the user. It is going.
[0009]
[Problems to be solved by the invention]
However, in this conventional receiving apparatus, it is assumed that one user performs accumulation and playback operations, and when a plurality of users accumulate programs, only the programs accumulated by one user are stored. There are cases where only programs that have been automatically deleted or accumulated by other users as a deletion candidate menu are presented as candidates.
[0010]
For example, when a plurality of users use such a receiving device with a storage function, a user A records only a program with a low priority, and a user B records only a program with a high priority. In some cases, the storage capacity is full when playback has not yet been performed. When user B tries to record next, what is recorded by user A is displayed as a deletion candidate list, and user B cannot determine whether these candidates can be deleted. Search for data that can be deleted from the list.
[0011]
As described above, in the conventional apparatus, it is not assumed that a plurality of users share, record, play back, or delete a broadcast signal, so that the storage device having a limited storage capacity can be used by a plurality of users. There is a problem that can not be done.
[0012]
The present invention assumes a use of a plurality of users, and a broadcast signal that can fully utilize a built-in storage device among a plurality of users by using the management information of the broadcast signal to be recorded including the user identification information. It is an object of the present invention to provide a recording apparatus and a broadcast signal recording method.

[0015]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present embodiment will be described in detail with reference to the drawings.
[0016]
<Structure of Broadcast Signal Recording Device According to the Present Invention>
As an example of the broadcast signal recording apparatus according to the present invention, a case of a digital broadcast recording apparatus will be described in detail. FIG. 1 is a block diagram showing an embodiment of a broadcast signal recording apparatus according to the present invention, FIG. 2 is a flowchart showing an example of update processing of user identification information, and FIG. 3 is a broadcast signal recording apparatus according to the present invention. 4 is a flowchart showing an example of management information display processing, and FIG. 5 is a diagram showing an example of management information stored in the broadcast signal recording apparatus according to the present invention.
[0017]
1, a broadcast signal recording apparatus according to the present invention includes a tuner 11 for receiving and demodulating an external broadcast signal and a storage connected to the demodulator for storing the demodulated broadcast signal. Device 16. Furthermore, a selector 12 that receives both the output from the tuner 11 and the output of the storage device and selects and outputs one according to the control signal, and a TS (Transport Stream) that receives the output signal from the selector 12 A TS processing / MPEG processing unit 13 that performs processing / MPEG (Moving Picture Expert Group) processing and a display control unit 14 that receives this output and generates a display signal are included. Furthermore, the storage device 16, the selector 12, and the display control unit 14 are connected to each other, and the storage / reproduction control unit 17 that controls the operation of the accumulation process and the reproduction process is provided. The storage / playback control unit 17 includes a CPU (Central Processing Unit), and is connected to an input processing unit 18 that receives input from a user and a memory 19. The output of the display control unit 14 is connected to a monitor 15 that displays content such as video of a broadcast signal.
[0018]
<Basic Operation of Broadcast Signal Recording Device According to the Present Invention>
In such a configuration, the broadcast signal recording apparatus according to the present invention performs real-time reproduction processing as follows. In other words, the demodulated signal received and demodulated from the outside is sent to the TS processing / MPEG processing unit 13 through the selector 12 and subjected to TS DEMUX (De-Multiplex) processing and MPEG decoding processing. The display control unit 14 formats the data so that it can be displayed on the monitor 15. Then, the program is displayed on the monitor 15 as a formatted video signal or the like.
[0019]
Further, as the accumulation process, a recording process designated as so-called absence recording or the like by the user can be performed. That is, when a program storage request is input from the user through the input processing unit 18, this is stored in the memory 19 or the like. The accumulation / reproduction control unit 17 is controlled by the accumulation / reproduction control unit 17 to accumulate the program in the accumulation device 16 at the designated time according to the accumulation request, and the TS processing / MPEG processing unit Based on SI (Specific Information) information extracted in step 13, information (date and time, title, etc.) relating to the accumulated program is stored in the memory 19 as management information for controlling the accumulation process.
[0020]
Further, as shown in FIG. 5, the management information stored here includes not only the storage order, the broadcast program title, and the billing contents, but also the viewing information, the user identification information, and the automatic deletion mode that characterize the present invention. It includes the presence or absence of.
[0021]
For the reproduction of the stored program, a reproduction request is input from the user through the input processing unit 18, and in response to this, the accumulation / reproduction control unit 17 reads the management information from the memory 19, and this is displayed on the display control unit 14, for example, OSD (On-screen display: On Screen Display) processing is performed and displayed on the monitor 15. The user selects a target program from the displayed list, inputs a reproduction instruction via the input unit, and in response to this, the accumulation / reproduction control unit 17 reads the target program data in the accumulation device 16. Then, the data is input to the TS processing / MPEG processing unit 13 via the selector 12 and the same processing as the real time reproduction is performed, and the reproduced program is displayed on the monitor 15.
[0022]
<Characteristic Operation of Broadcast Signal Recording Device According to the Present Invention>
Next, a recording process, a management information display process, and a user identification information management process using the user identification information of the present invention will be described in detail with reference to flowcharts.
[0023]
(User setting)
The user has information (for example, identifiable information such as the name of Ichiro Yamada and the personal nickname used by father, mother, brother, etc.) when accumulating programs, as shown in FIG. As shown, these user identification information is updated. That is, during the recording process, if there is a recording command from the input processing unit 18 for a specific program from the user (S41), this is prompted to input user identification information (user ID) on the screen (S42). . When the identification information is input from the user, the storage / reproduction control unit 17 that has received the user identification information stores the user identification information in the user identification area of the management information for storage processing stored in the memory 19. Set. If this is the second time or later, the user ID management table is updated as shown in the flowchart (S43). This can be set at the time of setting or after storage, and the same operation is performed. Then, content data is recorded and stored according to the user ID (S44).
[0024]
In FIG. 5 mentioned above, three registered users are shown, and one user is linked to each bit. For example, three users, father, brother, and Taro, are registered. , Dad, brother, and Taro are assigned in order from the top of the bit.
[0025]
Similarly, playback information and automatic deletion information are managed for each user. In the playback information, the target bit is defined as “1” when playback is completed, and “0” when playback is not performed. As the automatic deletion information for designating the mode, for example, “0” is assigned if the automatic deletion mode is given, and “1” is assigned as an example if the automatic deletion mode is not given and automatic deletion is impossible.
[0026]
(Broadcast data storage)
The case where a broadcast signal is recorded and stored using a user ID that is user identification information will be described. As shown in the flowchart of FIG. 3, when a recording command is received from a user (S21), the user ID that is user identification information is received. This is prompted on the screen to input (S22). Then, it is determined whether or not the storage capacity of the storage device 16 has a margin (S23). If there is a margin, the recording process is performed according to the above-described procedure (S24).
[0027]
When there is a free space (S23), it is determined whether data that the user thinks can be deleted exists in the storage device 16 (S26). This is the case, for example, when data recorded by the operating user exists in the storage device 16 and can be freely deleted. Or even if it is data of other users other than the user who is operating, when there exists a setting that this may be deleted, it corresponds to this. If there is no data that can be deleted, recording is stopped at this point (S25).
[0028]
If there is data that can be deleted (S26), it is determined whether automatic deletion is possible (S27). This is determined by referring to the parameter of FIG. 5 as to whether automatic deletion is possible. For example, “1” is disabled and “0” is enabled. If automatic deletion is impossible, as shown in FIG. 8 or FIG. 9, a deletion list is displayed to prompt manual deletion (S28). As will be described later, FIG. 8 shows a deletion candidate list when priority is set by genre, and FIG. 9 shows a deletion candidate list when priority is set by the price of pay broadcasting.
[0029]
In accordance with the erase candidate list, the corresponding data is erased from the storage device 16 in response to an erase instruction from the user (S29). If automatic deletion is possible (S27), the target image is automatically deleted (S30).
[0030]
By providing automatic deletion mode in this way and performing automatic deletion, it is possible to automatically delete items that have been stored but not played back when the free space in the storage unit has decreased. Can be used effectively.
[0031]
In addition, when displaying a list of deletion candidates, information indicating whether or not playback has been performed is displayed, or only information that has been played back is displayed by filter linking, so that the user can easily select deletion candidates.
[0032]
(Display of accumulated program list or deletion candidate list)
Next, display of a list of accumulated programs will be described below. When the stored program is reproduced, as shown in the flowchart of FIG. 4, the accumulation / reproduction control unit 17 reads management information from the memory 19 in response to a reproduction request input from the user through the input processing unit 18 (S31). The display control unit 14 performs, for example, OSD processing and displays the result on the monitor 15.
[0033]
In this case, since all data stored in the storage device is displayed, if the number stored is large, it is divided into several pages and displayed in, for example, recording order or category. When user identification information does not exist (S32), programs recorded and stored by other users are also displayed (S35).
[0034]
However, when user identification information for identifying itself is input through the input processing unit 18, the accumulation / reproduction control unit 17 reads only management information for the accumulation process for which the user identification is set from the memory 19. . The number of management information corresponding to the ID that is the user identification information is counted (S33). Then, the management information is displayed (S34).
[0035]
Various examples of display using user identification information are conceivable, and management information including user identification information is subjected to, for example, OSD processing by the display control unit 14 and displayed on the monitor 15 as shown in FIG. .
[0036]
In the example of FIG. 6, the management information edited according to the user identification information is simply displayed in the accumulated order. Here, it is also suitable to sort and display according to categories such as sports and dramas. As described above, it is possible to easily search and select stored programs by providing the user identification setting and the identification input unit.
[0037]
Further, management information must be displayed not only at the time of program reproduction but also at the time of setting for recording a program. That is, according to the user's storage instruction, programs can be sequentially stored up to the capacity of the storage device 16, but when the storage capacity of the storage device 16 reaches a certain value, the next program must be deleted unless a part is deleted. Cannot be stored. In other words, this is a case where steps S26 to S28 in the flowchart of FIG. 3 are reached.
[0038]
When an instruction to store the next program is input from the input processing unit 18 in such a state, the storage / playback control unit 17 examines the contents of the memory 19 and the automatic deletion flag is “permitted”. If there is one (the automatic deletion flag in FIG. 5 is “0”) (S27), the storage device 16 is controlled to delete the target program data (S30).
In response to this, the data in the memory 19 which is management information is also deleted and updated.
[0039]
Thereafter, the free space of the storage device 16 is calculated (S23), and if the free space sufficient for storing the designated program is secured, the storage device 16 is controlled to store the newly designated program. (S24), and this information is added to the management information in the memory 19 and updated.
[0040]
At this time, when automatic deletion is impossible, that is, when the automatic deletion mode is not set, or when there is no automatic deletion target even in the automatic deletion mode, it is not possible to secure a free space even by automatic deletion. In this case, for example, as shown in FIG. 7, after displaying a message such as “The capacity of the recording device is full. Display deletion candidates. Press the user selection button.”, User identification selection is performed. Thus, the display control unit 14 is controlled to display the gist on the monitor.
[0041]
Here, as a case where the automatic deletion is actually automatically deleted in the automatic deletion mode, for example, the automatic deletion may be performed after the reproduction is completed. Furthermore, a program with a limited period and when the period has passed is suitable as a condition for automatic deletion, but is not limited thereto.
[0042]
Next, when the user inputs information for identifying himself / herself from the input processing unit 18, the information recorded by the user is extracted from the memory 19, and a deletion candidate list is configured and displayed on the monitor 15 as shown in FIG. To do. In this example, data that can be automatically deleted is deleted, and priorities such as serial drama, sport, and replayed program are weighted in order, and are displayed as deletion candidates in order from the lowest priority. By doing so, it is possible to easily determine the program to be deleted because the programs stored by the user can be listed without performing deletion selection for those stored by other users.
[0043]
In this way, when the free space in the storage unit is reduced, the deletion candidate list is presented for each user, so that a program that other users want to keep may be deleted by mistake. The program to be deleted can be easily selected.
[0044]
(Display considering accounting information)
Further, an example of display that takes account information into account will be described below. That is, there are free programs and pay programs in broadcasting, and among pay programs, there are a tier program that is contracted for each channel in advance and a PPV (Pay Per View) program that is applied for purchase and reproduced for each program. In general, pay programs that are paid to play are more demanding to save, so when displaying the above deletion candidate list, if the display data is configured in consideration of this information, it is displayed as shown in FIG. The Here, free programs are listed above, charged programs are listed for each channel, and finally charged programs are listed last for each program.
[0045]
Furthermore, when the PPV program is stored and reproduced, the number of reproduction may be limited or the reproduction period may be controlled. For PPV programs with these restrictions, for example, programs that cannot be reproduced exceeding the reproduction frequency limit or those that cannot be reproduced beyond the reproduction period are displayed in the deletion list in order, thereby making it easy to select a program that can be deleted. . For example, as shown in FIG. 10, when there is an expired PPV program with a reproduction deadline, the fact that the recorded user has not been reproduced can be recognized by notifying the fact and deleting it. It is preferable to propose to delete them.
[0046]
Thus, by displaying the accounting information at the same time when displaying the list of deletion candidates, the user can easily select the deletion candidates.
[0047]
As described above, user identification information is set for a program to be stored, a list of stored programs is displayed for each user, and a user is selected as a deletion candidate when the capacity of the storage device is full. By displaying so as to present the data with the lowest storage priority every time, it is possible to easily select the stored data recorded by a plurality of users.
[0048]
Further, even when the entire data list is displayed, as shown in FIG. 11, by displaying the screen divided into a plurality of areas, it is very easy to edit even the accumulated data performed by a plurality of users. In addition, there may be a case where each user is displayed in different colors and the user identification information can be used effectively. Furthermore, it is preferable to display after sorting according to some condition.
[0049]
In this embodiment, it is preferable that the user's selection information is input by, for example, inputting a key assigned to the remote controller R shown in FIG. That is, in FIG. 12, keys A to C are assigned to three users. For example, key A is “dad”, key B is “older brother”, key C is “Taro”, etc. Setting is suitable.
[0050]
Thus, by assigning the input of information for identifying the user to the button of the remote controller, the user interface at the time of information input can be improved.
[0051]
Further, by pressing the key A after the message as shown in FIG. 7, the program accumulated by the father as shown in FIG. 8 can be displayed. In addition to assigning such a selection input unit to a key, it is also preferable to perform the selection input unit in a menu format by OSD.
[0052]
With the various embodiments described above, those skilled in the art can realize the present invention. However, it is easy for those skilled in the art to come up with various modifications of these embodiments, and have the inventive ability. It is possible to apply to various embodiments at least. Therefore, the present invention covers a wide range consistent with the disclosed principle and novel features, and is not limited to the above-described embodiments.
[0053]
For example, although the above embodiment has been described by taking a digital broadcast recording apparatus for digital broadcasting as an example, even if the target is a broadcast signal of an analog signal, the operation and effect of the present invention are completely equivalent.
[0054]
【The invention's effect】
As described above in detail, according to the present invention, in the broadcast signal recording apparatus for recording and storing the broadcast signal , the management information such as the billing information of the recorded and stored broadcast signal is stored using the user identification signal. By displaying and managing, the storage capacity resource of the broadcast signal recording apparatus can be effectively utilized by a plurality of users.
