Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a digital broadcast receiving apparatus.
In recent years, digital broadcasting such as CS (Communication Satellite) broadcasting has begun to be used in actual operation. In such digital broadcasting, for example, a huge number of channels such as 100 channels are provided, and a viewer who is a user selects one favorite channel from the huge number of channels and views the broadcast. It will be.
[0002]
[Prior art]
In digital broadcasting such as CS broadcasting, since one channel is selected from the enormous number of channels as described above, the operation for the selection becomes extremely complicated for the user.
For this reason, various broadcast selection mechanisms have been proposed. Some examples are (1) JP-A-10-191194, (2) JP-A-10-215419, and (3) JP-A-10-304271.
[0003]
In the above conventional example (1), a program or channel designated by a user's request can be marked, and program guide display is performed for the marked program or channel.
The conventional example {circle around (2)} is to allow the user to input keywords such as performers and song titles, create a program table that makes it easy for the user to find a program that the user wants to view, and output to the user.
[0004]
In the above conventional example (3), the number of times the user has viewed the program is recorded in a memory so that the target program can be searched efficiently.
[0005]
[Problems to be solved by the invention]
The present invention provides a new digital broadcast selection mechanism which is not found in the conventional examples (1), (2) and (3).
For example, when looking at a digital broadcast receiver mounted on a vehicle, such a receiver for a vehicle requires no operation during driving if one or more genres or titles of the user's preference are specified in advance. If only the program types having these genres and titles can be received continuously and automatically from one to the next, a new service that is completely unthinkable in analog broadcasting up to now can be provided.
[0006]
SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a digital broadcast receiving apparatus that can continuously and automatically receive only a user's favorite program type from one to the next.
[0007]
[Means for Solving the Problems]
FIG. 1 is a basic configuration diagram of a digital broadcast receiving apparatus according to the present invention.
The digital broadcast receiving apparatus 1 according to the present invention is roughly composed of a receiver 2 and a broadcast selection function unit 3. More specifically, a digital broadcast receiving apparatus 1 having a receiver 2 that receives a broadcast including at least program type information b as additional information B from an antenna ANT and provides video / audio information AV to a user. The broadcast selection function unit 3 cooperates with the receiver 2 to retrieve the program type designated by the user from the program type information b and stores it in the database DB together with the time information t. The function of selecting the items in time series and sequentially providing them to the user is achieved.
[0008]
Of the receiver 2 and the broadcast selection function unit 3 constituting the digital broadcast receiver 1 according to the present invention, the function unit 3 is an element that characterizes the present invention, and is separated from the receiver 2 for easy understanding. Are shown as independent elements. Actually, it is desirable to be formed integrally with the control unit (microcomputer) 4.
The receiver 2 itself may have a known general configuration. For example, an RF unit (“RF”) that constitutes a tuner, an RF amplifier, and the like, a decoder DEC that decodes the additional information B including the program type information b and the like and returns them to the control unit (microcomputer) 4, and the microcomputer 4 A memory 5 for holding the program and necessary data, a key 7 for inputting various designation information designated by the user, and an interface 6 for converting the input signal into a signal that can be received by the microcomputer 4. Thus, a user's favorite program is provided as an audio / video broadcast from the monitor (M) 8 and / or the speaker (SP) 9.
[0009]
As shown in the figure, the broadcast selection function unit 3 according to the present invention that cooperates with such a receiver 2 includes a program type information extraction unit 11, a database creation unit 12, a database (DB) 13, and a database search unit. 14 and search determination means 15. The user memory (UM) 17 adjacent to the database 13 will be described later.
[0010]
The main functions of each of the means 11, 12, 14 and 15 are as follows.
The program type information extraction means 11 extracts program type information b including time information t from the additional information B relating to the program attributes.
The database creation means 12 creates a database (DB) 13 that stores program type information b including the extracted time information t.
[0011]
The database search means 14 searches the database 13 for a program type designated by the user, and sequentially provides the audio / video information AV related to the designation from the receiver 2 in time series.
The search determination means 15 performs determination at the time of the search according to the selection specific information designated by the user. Here, the selection specifying information means information for the user to specify selection related to a program.
[0012]
By each means described above, the user can automatically and continuously watch his / her favorite program continuously from one to the next.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 2 is a diagram showing a specific configuration example of the search determination unit 15 shown in FIG. The functions obtained by the present invention will become more apparent from the description of each part shown in the figure.
The elements shown in this figure are: priority designation unit 21, program competition notification unit 22, time interference rate calculation unit 23, record instruction unit 24, recording selection unit 25, record reproduction unit 26, record reproduction stop unit 27, and record reproduction selection. The unit 28 operates in conjunction with the microcomputer 4. Note that it is not necessary to form all of these elements 21 to 28 at the same time as the search determination means 15, and any number may be formed as necessary.
[0014]
Hereinafter, it will be described in detail with reference to a program table and a flowchart schematically shown.
FIG. 3 is a time table representing the first example of the present invention.
FIG. 4 is a flowchart showing the operation under the first example.
Referring to the program table in FIG. 3, for example, three types of broadcast services, service A, service B, and service C, are provided, and in each broadcast service, the various program types shown are time zones shown on the left side of the figure. Will be broadcast in Japan.
[0015]
The above-described selection specifying information is information specified by the user as to which of the genre, title, performer, etc. is selected, and these genre, title, performer, etc. are collectively referred to as a program type.
In the example of FIG. 3, the user has selected sports as the selection specifying information, and sports C → sports B → sports A from time to time, from the monitor 8 and the speaker 9 of the receiver 2, Automatically and continuously provided to the user. For example, sports C is a broadcast of tennis, sports B is a baseball, and sports A is a sumo broadcast.
In addition, news A and B, pops (POP) A and B, and weather forecast A are also broadcast.
[0016]
FIG. 4 shows an operation example for the continuous reception described above.
Step S11: The user inputs selection specific information using the key 7, for example. In this example, sports are selected.
Step S12: The program type information extracting means 11 analyzes EPG (Electronic Program Guide) information as the additional information B, and simultaneously analyzes the selection specific information in step S11.
[0017]
Step S13: The database creation means 12 creates the above-described continuous reception database (DB) 13 (illustratively, it is a hatched database in FIG. 3).
After the above steps, the program type (sports) selected by the user can be continuously received.
[0018]
Step S14: The database search means 14 determines whether the time of the program registered in the database 13 has come.
Step S15: When it is determined that the time has come (Yes), the service is switched to the service registered in the database 13. In the example of FIG. 3, for example, at time 1:00, the sport C is switched to the sport B.
[0019]
As described above, continuous reception can be performed.
FIG. 5 is a time table representing a second example of the present invention.
FIG. 6 is a flowchart showing the operation under the second example.
In the first example of FIGS. 3 and 4, a single program type (sports) was selected by the user. In practice, however, the user may wish to select two program types or more.
[0020]
In such a case, the priority designation unit 21 in the search determination unit 15 shown in FIG. 2 functions effectively.
When there are a plurality of program types specified by the above-described selection specifying information, the priority specifying unit 21 obtains and holds information on the priority viewing order of these program types from the selection specifying information, and the same time period When these program types compete with each other, the highest priority program type is designated.
[0021]
For example, referring to the program guide in FIG. 5, it is assumed that the user has selected a program type “sports” and another program type “pops (POP)”. Further, priority viewing order is designated for these two program types. In this example, pops (POP) is the first priority (top priority), and sports is the second priority.
Then, in FIG. 5, the sports B starting at time 2:00 and the pops POP · B starting at time 3:00 compete from this time 3:00. In this case, the priority designation unit 21 Will switch the broadcast from the second priority sports B to the first priority (top priority) pops (POP · B).
[0022]
FIG. 6 shows an operation example when there is the above-described priority designation.
Step S21: The same as step S11 (FIG. 4), but information regarding the priority order is also input.
Steps S22 and S23 are the same as steps S12 and S13 (FIG. 4), and continuous reception starts.
[0023]
Step S24 is the same as step S14 (FIG. 4).
Step S25 corresponds to step S15 (FIG. 4), but here, the occurrence of program type conflict is recognized and the program type is switched to the highest priority program type.
As described above, collision between programs that can occur when two or more programs are selected can be adjusted.
[0024]
FIG. 7 is a time table representing the third example of the present invention.
FIG. 8 is a flowchart showing the operation under the third example.
In the second example of FIGS. 5 and 6, the above-described conflict that may occur when a plurality of types of programs are selected is adjusted by specifying the priority order. In this third example, the conflict occurs to the user. I will only tell you the facts. For this purpose, the program conflict notification unit 22 shown in FIG. 2 is provided.
[0025]
The program conflict notification unit 22 notifies the user of a conflict when a plurality of program types specified by the selection specifying information compete in the same time period.
For example, referring to the program table of FIG. 7, the user selects the program type “sports”, but sports A (sumo) starting from time 3:00 is sports B (baseball) starting from time 1:00. ). Accordingly, the fact of this conflict is notified to the user, and either one is selected by the manual operation. The choice is whether to continue the sport B that has been heard so far or to switch to a new sport A. Therefore, in this case, if the EPG information (the contents, the total time, etc.) about the new sport A to be competing is notified at the time of notification to the user, the user becomes easier to select.
[0026]
FIG. 8 shows an example of operation when notifying the user of the occurrence of a conflict as described above.
Steps S31, S32, S33, S34 and S36 are the same as steps S11, S12, S13, S14 and S15 of FIG.
Particularly noteworthy steps are S35 and S37. In step S35, the database search means 14 detects a service conflict. In step S37, the program conflict notification unit 22 (FIG. 2) notifies the user to that effect. This notification may be a beep sound from the speaker 9 or an appropriate screen display on the monitor 8.
[0027]
The user who has received the notification can select the sport A or the sport B by manual operation by inputting from the key 7, for example. In the above description, the example of the same genre, sports A and B, is shown, but it may be a different genre such as sports and pops.
As described above, it is possible to select an optimal program by notifying the user of the collision of two or more programs.
[0028]
FIG. 9 is a time table representing the fourth example of the present invention.
FIG. 10 is a flowchart showing the operation under the fourth example.
In the third example of FIG. 7 and FIG. 8, when a plurality of types of program types conflict, it is left to the user to decide which one to select, but in this fourth example, the broadcast selection function unit 3 Make decisions on behalf of the user. This criterion is a time interference rate (described later), and the time interference rate calculator 23 shown in FIG. 2 functions effectively.
[0029]
The time interference rate calculating unit 23 calculates a time ratio in which each program type is interfered by another program type when the same program type as the program type specified by the selection specifying information described above competes. An interference rate is selected, and a program type with a small time interference rate is preferentially selected.
For example, referring to the program table of FIG. 9, the user selects the program type “sports”, but sports A1, sports B, and sports C2 compete in the time zone represented as “competition” in the figure. It has been.
[0030]
In such a case, the contention is not automatically adjusted by the user, but is automatically determined by the time interference rate calculator 23.
According to the example of FIG. 9, the total proportion of the sports C2 is interfered by the sports B (also by the sports A1) is 100%. Looking at the sport A1, the time ratio of the total broadcast time being interfered by the sport B is 100%.
[0031]
On the other hand, regarding the sport B, during the entire broadcasting time, the time ratio of interference by the sport A1 and the sport C2 is 100% or less. Here, when the time ratio is defined as the above-described time interference rate R,
R = t / T × 100 [%]
It is. T is the total broadcast time of the program of interest, and t is the time when this program of interest overlaps with other selected programs.
[0032]
According to the example of FIG. 9, the time interference rates R (A1), R (B) and R (C2) of the sports A1, B and C2 are as follows.
R (A1) = 1.0H / 1.0H = 100%
R (B) = 1.0H / 2.0H = 50%
R (C2) = 0.5H / 0.5H = 100%
It becomes. Therefore, R (B) having the smallest value of 50% is selected with the highest priority. That is, sport B is selected and received.
[0033]
FIG. 10 shows an operation example according to the above-described time interference rate.
Steps S41, S42, S43, S44 and S46 are the same as steps S11, S12, S13, S14 and S15 of FIG. 4, respectively.
Step S45 is the same as step S35 of FIG.
Therefore, step S47 in this figure is the step that characterizes this fourth example most, and one program among competing programs is automatically selected based on the time interference rate R described above.
[0034]
The time interference rate R may be calculated when program contention occurs, or may be calculated in advance when EPG information is received and stored in the database 13.
As described above, when two or more programs compete, the program having the minimum time interference rate is automatically selected.
[0035]
FIG. 11 is a time table showing the fifth example of the present invention.
FIG. 12 is a flowchart showing the operation under the fifth example.
Referring to FIGS. 5, 7, and 9, there are programs that are not selected because other programs are preferentially selected in each time zone described as “conflict” in each figure. The sports B in FIG. 5 (second example), the sports A or sports B in FIG. 7 (third example), and the sports A1 and sports C2 in FIG. 9 (fourth example).
[0036]
If these non-selected programs are discarded as they are, the broadcast program at the corner will be wasted. Therefore, in the fifth example, these non-selected programs are recorded (recorded / recorded). Therefore, the record instruction unit 24 shown in FIG. 2 functions effectively.
When a plurality of program types designated by the above-described selection specifying information compete for the same time period, the record instruction unit 24 records / records the program that is not selected according to the selection specifying information. It is an instruction.
[0037]
For example, referring to the program guide in FIG. 11, if the user selects a sport according to the selection specifying information, the sport A1 and the sport B compete from time 1:00. Therefore, based on the second example (FIG. 5), the second-priority sport A1 is not selected, and based on the third example (FIG. 7), the user manually selects (sport B is selected). ) Deselects the sport A1, and based on the fourth example (FIG. 9), the sport A1 having a large time interference rate R is deselected.
[0038]
The program of the sport A1 that is not selected in this way is recorded / recorded in accordance with an instruction from the record instruction unit 24 under the fifth example.
FIG. 12 shows an operation example of the record instruction described above.
Steps S51, S52, S53, S54 and S56 are the same as steps S11, S12, S13, S14 and S15 of FIG. 4, respectively.
[0039]
Step S55 is the same as step S35 of FIG.
Therefore, step S57 in this figure is the step that characterizes this fifth example most, and the program (sports A1) that has not been selected is recorded by the recorder / recorder 16 (FIG. 1). Note that recording / recording means performing either one or both of recording and recording.
[0040]
As described above, it becomes possible to automatically save a non-selected program.
FIG. 13 is a flowchart showing the sixth example of the present invention.
This sixth example is performed by the recording selection unit 25 shown in FIG.
When the above-described fifth example is implemented, if the non-selected program is, for example, news, it is sufficient to reproduce the sound of the news when the program / recorder 16 reproduces the program later. Can know. Then, if the program has an attribute such as news, it is possible to select only recording without recording. In particular, in the case of an in-vehicle digital broadcast receiver, it is more convenient to reproduce only the recording. This applies not only to news, but also to stories like rakugo.
[0041]
As described above, based on the attribute of the non-selected program obtained from the additional information B such as EPG information, the recording selection unit 25 has an attribute that the non-selected program type does not require recording. It works to specify that only recording is selected.
Referring to FIG.
Step S61: The attribute of the service (for example, the above news) that is not selected and recorded is searched.
[0042]
Step S62: If the attribute is known as news, the corresponding recording medium is automatically selected. Specifically, the recorder (16) is automatically selected.
Step S63: During the non-selection, the above news is recorded by the recorder (16).
As described above, it is possible not only to record a non-selected program but also to automatically select the record medium.
[0043]
FIG. 14 is a time table showing the seventh example of the present invention.
FIG. 15 is a flowchart showing the operation under the seventh example.
The seventh example relates to the reproduction of the program recorded (recorded / recorded) in step S57 (FIG. 12) of the fifth example and step S63 (FIG. 13) of the sixth example. For this purpose, the record reproducing unit 26 shown in FIG. 2 is provided.
[0044]
When the above-mentioned database search means 14 searches the database (DB) 13 for a free time when there is no program corresponding to the program type designated by the user, the record playback unit 26 The non-selected program recorded (recorded / recorded) by the record instruction unit 24 is reproduced.
For example, referring to the program guide in FIG. 14, it is assumed that the user has selected sports as the selection specifying information. In this example, sports A1 and sports B compete.
[0045]
Then, according to the second example (FIGS. 5 and 6), the third example (FIGS. 7 and 8), or the fourth example (FIGS. 9 and 10), either sport A1 or sport B is preferentially selected. Is done. If the sport A1 is not selected, the sport A1 is recorded in the recorder / recorder 16 (FIG. 1) according to the fifth example (FIGS. 11 and 12) or the sixth example (FIG. 13). To be recorded.
[0046]
Based on this seventh example, the recorded program of sports A1 is searched for a later free time, and if this free time is available, it will be played back during that time zone. In the example of FIG. 14, since there are only live A and live B programs and no selected sports program in the time zone from 3:00, this is the free time (“free” in the figure), Sports A1 can be played.
[0047]
FIG. 15 shows an example of the reproduction operation of the non-selected program in the idle time described above.
Step S71: The database search means 14 (FIG. 1) determines whether or not there is a program to be received (the above-described sports program selected by the user) in the database 13. This determination is made by the record reproducing unit 26.
Step S72: If there is the sports program, it is switched to this. This step S72 is the same as step S15 of FIG.
[0048]
Step S73: If the result of the determination is No in step S71, the required free time has been found. Therefore, the recorded sport A1 is reproduced during this idle time.
As described above, the non-selected program is reproduced using the idle time.
[0049]
FIG. 16 is a time table representing the eighth example of the present invention.
FIG. 17 is a flowchart showing the operation under the eighth example.
According to step S73 (FIG. 15) in the seventh example, when the reproduction of the non-selected program is started by the record reproduction unit 26 (FIG. 2), the reproduction is continued until this is completed.
[0050]
However, during the reproduction, broadcasting of the program (sports) selected by the user may be newly started. FIG. 16 illustrates this. The sport A1 that is not selected due to competition at time 12:00 is recorded in the record instruction unit 24. When the above-mentioned vacant time is found (after time 2:00 in this figure), the recorded sport A1 is reproduced in that time zone. According to the seventh example, the reproduction is continued until the sport A1 is completed.
[0051]
However, as shown in the figure, the sport A2 is newly started at time 3:00. In this case, the sport A1 of one and a half hours has not been played back in the free time of one hour, but the rest can be seen later, so the playback of the sport A1 is forcibly stopped and the service ( Switch to sport A2). This is an eighth example. For this purpose, a record reproduction stop unit 27 shown in FIG. 2 is provided.
[0052]
When the above-described database search means 14 searches the database 13 for a program corresponding to the program type designated by the user (in this case, sport A2), the record reproduction stop unit 27 records the non-selected recorded items. The function of stopping the reproduction of the program (sports A1) is achieved.
FIG. 17 shows an operation example of the above-described record reproduction stop.
[0053]
Steps S81 and S82 are the same as steps S71 and S72 of FIG. 15, respectively.
Step S83 is the same as step S73 in FIG. Therefore, steps S84 and S85 are newly added.
However, in step S83, a check routine is included. This check routine is performed periodically at predetermined intervals, for example, every 30 seconds during service reproduction. However, the check routine is executed using a short time such as during the vertical flyback period during reproduction.
[0054]
In this check routine, step S84 is executed. The contents of this step are exactly the same as in step S81. If the sport A2 from time 3:00 in FIG. 16 is found in step S84, the process immediately reaches step S85 to stop the reproduction and at the same time, reaches step S82 and starts receiving the broadcast of the sport A2. Instead of the above check routine or step S84, the database search means 14 may find the sport A2 and stop the above reproduction at that time.
[0055]
As described above, even when a program recorded in the non-selected state is being played back, it is possible to immediately switch to this when a new user-selected program starts.
FIG. 18 is a flowchart showing a ninth example of the present invention.
In the description of the eighth example, one program is not selected (sport A1). However, there may be two or more programs that are not selected.
[0056]
In such a case, in the ninth example, an optimum one can be selected and reproduced from two or more recorded programs. Therefore, the record reproduction selection unit 28 shown in FIG. 2 functions effectively.
When there are a plurality of non-selected programs recorded (recorded / recorded) in the recorder / recorder 16 (FIG. 1), the record playback selection unit 28 selects a program that is to be played back within the above-mentioned free time. The record reproduction unit 26 reproduces the data.
[0057]
For example, if there are two recorded non-selected programs, one of which has a total playback time of two and a half hours and the other is one and a half hours, the above free time has a two-hour time zone. When it is determined, the latter program (one and a half hours) is selected.
FIG. 18 shows an example of the reproduction selection operation when there are two or more recorded programs as described above.
[0058]
Steps S91 and S92 are the same as S71 and S72 of FIG.
Therefore, step S93 is a characteristic step of the ninth example. In this step S93, the database search means 14 (FIG. 1) calculates the free time (for example, “free” shown in FIG. 16) existing in the database (DB) 13.
Furthermore, a service (program / record) that has been recorded (recorded / recorded) with a total playback time within the free time (a service that can be played back in the free time) is automatically selected and played, and provided to the user. . When there are a plurality of reproducible programs, a program list may be displayed to the user, or the oldest time stamp may be automatically selected.
As described above, it is possible to automatically select and play back a program that can be completely viewed within a vacant time among several recorded programs.
[0059]
Finally, a tenth example will be described. Here, referring to FIG. 1 again, a user memory (UM) 17 provided in the database (DB) 13 is shown. This role is as follows.
Assuming that two users U1 and U2 share one vehicle, the above-mentioned selection specifying information is different for each user. Then, the users U1 and U2 are troublesome because they must reset their selection information each time the vehicle engine is started.
[0060]
Therefore, the selection specific information is individually provided for the users U1 and U2. This is shown in the user memory (UM) 17 of FIG. 1, the upper part of which is for U1, and the lower part is for U2. The user only has to specify whether it is for U1 or U2 from the key 7 when starting the engine. If there are three or more users, a memory area corresponding to that number may be prepared.
[0061]
FIG. 19 is a flowchart showing the tenth example of the present invention, and shows an operation example for setting the above-described selection specific information for each user.
The flowchart in this figure is the same as the flowchart shown in FIG. 6 (second example), and steps S102 and S103 in this figure are the same as steps S22 and S23 in FIG. 6, respectively. Therefore, step S101 in this figure is a step characterizing the tenth example.
[0062]
In this step S101, the database search means 14 identifies which user is the viewer among the plurality of users (U1, U2,...). For example, identification is performed by key input indicating the user. Thereafter, selection specific information unique to the user is read from the user memory 17.
[0063]
【The invention's effect】
As described above, according to the present invention, only a user's favorite service can be continuously received from digital multi-channel services, and the user can continuously receive the service without being aware of the selection of the program. A comfortable service environment is provided without the need for selection. Since the labor of selection can be saved, it is particularly suitable for in-vehicle use.
[0064]
The first example is a typical example of continuous reception.
According to the second example, even when two or more kinds of user's favorite programs are selected, the competition between them can be optimally adjusted.
According to the third example, the user can grasp the broadcast status of the favorite service without omission and the room for program selection is widened.
[0065]
According to the fourth example, the idle time during continuous reception is reduced as a whole, and it can be enjoyed for a longer time, and the useless time during reception can be reduced.
According to the fifth example, the user can enjoy the favorite service without omission.
[0066]
According to the sixth example, it is possible to specialize only the recording function in the recording / recording device 16 to save the required space and reduce the cost. Further, when the monitor (M) 8 is shared with, for example, an in-vehicle navigation system, it is not necessary to interfere with the navigation.
According to the seventh example, for example, while driving, a favorite program can be enjoyed for a long time without waste.
[0067]
According to the eighth example, the user's favorite program can be enjoyed without waste, for a long time, and without a program selection operation.
According to the ninth example, it is possible to enjoy the program being played that has been enjoyed for a long time without ending the program halfway, and to reduce wasted time.
According to the tenth example, once each user sets his / her own selection specification information, all the start of favorite services can be known for each user without any setting operation thereafter, and therefore can not be overlooked.
