Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a TV program viewing apparatus having the following functions. (1) Function of using an electronic program guide (EPG). (2) A function of selecting and presenting a program according to the user's preference from the EPG based on the content and type of the user's past viewed programs. (Hereinafter referred to as a “recommended function.”) (3) Means for accumulating the program being received in the storage device, and the program stored in the storage device is stored within the storage range even during the accumulation process. A function of displaying the program from an arbitrary position, and temporarily stopping program display and changing the display speed during program viewing by a user operation. (Hereinafter, it will be referred to as “time shift playback function”.)

[0002]

2. Description of the Related Art Conventionally, in a TV program viewing apparatus, there is an invention in which a program according to a user's preference is selected from an EPG and presented based on the content and type of the user's past viewed program. For example, there is a "program selection device and program selection system" (Japanese Patent Application Laid-Open No. 11-75128). This technology and its similar technology are usually realized by the following two stages of processing.-Stage (1): a process of grasping a user's past viewed programs. Step (2): a process of selecting and presenting a program according to the user's preference from the EPG based on the user's past viewed programs.

An example of the contents and procedure of each process will be described below. The step (1) is a process of grasping the past viewing program of the user. First, a process for recording the following operations on the user's TV program viewing apparatus is performed. (A) When the user operates the TV program viewing apparatus, it is considered that the user has started viewing the program, and the start of viewing is recorded. (B) When the user stops the TV program viewing apparatus, it is considered that the viewing of the program has been finished, and a record of the viewing end is left. (C) When the user changes the channel selection of the TV program viewing apparatus, it is considered that the program being viewed has been switched, and a record of the viewed program change is left. These records are called viewing history. In the viewing history, information on the time when the operation occurred is recorded together with the content of the operation of the user.

[0004] Then, by using the operation time information to collate the recorded content with the EPG, it is possible to grasp what kind of program the user has watched. Further, at the time of collation with the EPG, the user simply grasps not only which program the user has watched but also what percentage of the broadcast time of the program the user has watched.

[0005] This stage (1) also includes a means for the user to input not only whether the user has just watched the program but also how much interest he or she is interested in the program. It is. This input records how much interest each program has, for example, as a numerical value.

[0006] The above-mentioned step (2) is a process of selecting and presenting a program according to the user's preference from the EPG based on the user's past viewing program. By using EPG,
For a program that the user has viewed in the past, a sentence describing the program content can be obtained. In addition, EPG
By using, a program having a content description similar to the content of a program viewed by a user in the past can be searched from programs scheduled to be broadcasted. Then, the search result is presented as a recommended program according to the user's preference.

[0007] For programs that the user has watched in the past,
The degree of interest in the viewed program is calculated using a value of “weight” according to what percentage of the broadcast time is viewed, and when a recommended program is presented, the search result is determined according to the “weight”. Is changed.

[0008] More specifically, when a user watches a program for a long time, it is considered that the user has a greater interest in the program than when the user watches the program for a short time. When a is searched, the search result is preferentially presented, such as placing the search result at a higher position. Similarly, if the user has input the degree of interest in the program during viewing, the degree of interest is used when presenting a search result. When searching for a similar program, the result of a search based on a program with a high degree of interest is presented to the top. Through the above two-stage processing, the degree of interest of the user is reflected in the presentation result of the recommended program.

[0009]

The above prior art has the following problems in the processing of the above-mentioned step (1). Problem 1: The content of the operation of the TV program viewing device by the user is recorded as a viewing history, so that the user can know what kind of program the user is viewing. However, the actual T
In viewing a V program, even if the TV program viewing apparatus has displayed the same program for a long time, the user does not always actually watch the program in front of the TV program viewing apparatus. It is a common phenomenon in the actual TV program viewing that the user leaves the seat while the apparatus is operating. In this case, the user program viewing state detected by the TV program viewing device does not reflect the actual user viewing situation. Therefore, the presented program does not reflect the user's preference.

Problem 2: Even if a means for detecting whether a user is present is also used in front of the TV program viewing apparatus, how concentrated the user is watching the program. Until, I can not grasp. In general, when watching TV programs, "watching while watching" is often performed, and even if a user is not interested in the program, the user may often be watching the TV program for a long time in front of the TV program viewing apparatus. appear. Also in this case, the program viewing state of the user detected by the TV program viewing apparatus does not reflect the actual viewing state of the user. As a result, the presented program does not reflect the user's preference.

Problem 3: If the user has means for inputting the degree of interest in the program being viewed, such an input operation is not indispensable for viewing the program.
Therefore, it cannot be expected that all users will perform such an input operation. If the user does not perform an input operation, the degree of interest in the program cannot be directly grasped. In addition, since this input operation is not related to the normal operation of the user at the time of viewing the program, the user may perform an erroneous operation on an uninterested program.
A case where the user inputs that he or she is interested can easily occur.
If an erroneous operation is performed, the user's program viewing state does not reflect the actual state. As a result, the presented program does not reflect the user's preference.

As described above, in the prior art, a situation in which a program different from the user's preference is erroneously regarded as having the user's interest easily occurs. As a result, even if the processing of the step (2) is functioning normally, a program different from the user's actual preference is searched, and the recommended function is not originally recommended. A program is presented by mistake. The present invention
To solve these problems, it is a TV program viewing program that presents a program according to the user's true taste without requiring the user to perform any special operation for the recommended function. It is intended to provide a device.

"Weight" reflecting the degree of interest of the person can be given.

Hereinafter, the reproduction operation recording means 14, the operation storage device 15, and the reproduction range obtaining means 1 which are the features of the present invention will be described.
6, the processing of the number-of-reproductions obtaining means 17, the reproducing speed obtaining means 18, the weight calculating means 19, and the operation record rearranging means 20 will be described. This process is divided into the following three steps. Step 1: This is a process of acquiring a record of a user's reproduction operation. Step 2: a process of obtaining a reproduction result based on the record of the reproduction operation. Step 3: This is a process for calculating the degree of interest of the user based on the reproduction result obtained in step 2.

Next, the flow of processing in each step will be described in order for each step. 1. Step 1 processing First, step 1 is a process of acquiring a record of a user's reproduction operation, which is executed by the reproduction operation recording means 14, and is a process that is performed while the user is performing time-shift reproduction.

FIG. 2 is a flowchart showing the algorithm of the processing in step 1. 1-1. Description of Flowchart of Step 1 First, every time a user performs an operation on the reproduction operation means 6, the operation content is acquired from the reproduction operation means 6 (step S201) and transmitted to the reproduction operation recording means 14. . It is determined whether the acquired type of operation is a “start of time-shift playback” operation (step S202). If “start of time-shift playback” is performed, the process proceeds to step S203. If so, step S again
Returning to 201, the acquisition of the operation content is repeated. In step S203, the operation content of the user at the time of starting the time shift reproduction is recorded in the operation storage device 15.

In this embodiment, when the time-shift reproduction is started, the speed is constant (1.0 times speed), as in the normal viewing state.
To continue playback. In this case, the operation storage device 1
5, the playback speed is “1.0”, the playback point time is the same as the current time, and the operation content is “playback start”.
Remember each. At this time, the current time at which the time shift reproduction is started is also recorded in the operation storage device 15 together.

Next, similarly to the processing in step S201,
Each time the user performs an operation on the reproduction operation means 6,
The contents of the operation are transmitted from the reproduction operation means 6 to the reproduction operation recording means 14 and acquired (step S204). Then, similarly to the processing in step S203, step S20
The operation content of the user obtained in the process 4 is stored in the operation storage device 15 (step S205). Thereafter, it is determined whether or not the operation content of the user recorded in step S205 is "end of time shift reproduction" (step S20).
6) If "end of time-shift reproduction" is reached, the current time at which the time-shift reproduction is ended is recorded in the operation storage device 15, and step 1 is ended. If it is not "end of time shift reproduction", the process returns to step S204, and the acquisition of the operation content of the user is repeated.

1-2. Description of the processing content of step 1 When the user's operation content obtained from the reproduction operation means 6 becomes "start of time-shift reproduction" in steps S201 to S203, the recording process is started.

Thereafter, in steps S204 and S205, each time the user operates the reproduction operation means 6, the program reproduction means 3 obtains the time at which the currently reproduced part is recorded and the reproduction speed. The set of the operation content, the time information, and the reproduction speed are recorded in the reproduction operation recording means 14 again.
At this time, in the order in which the user operates the reproduction operation means 6,
It is recorded in the reproduction operation recording means 14.

In step S206, this step 1 is repeated until the user operates "end of time shift reproduction" with the reproduction operation means 6.

Reference numeral 301 denotes an “end button” for terminating the time-shift reproduction operation, reference numeral 302 denotes a “return button” for returning a reproduction point to the past, reference numeral 303 denotes a “pause button” for temporarily stopping reproduction, and reference numeral 304 denotes a reproduction button. , A "forward button" for moving the playback point to the future, and a "play button" 305 for restarting the temporarily stopped playback. A “constant speed playback button” 306 changes the playback speed to a constant speed (1.0 times).
307 is a reproduction speed, slow reproduction (less than 1.0)
308 is a "high-speed playback button" for changing the playback speed to high-speed playback (greater than 1.0). Reference numeral 309 denotes a bar indicating a recordable time of the program, reference numeral 310 denotes a bar indicating a time at which the program is already recorded, and reference numeral 311 denotes a pointer indicating a currently reproduced portion.

The reproduction operation means 6 has, in addition to those shown in FIG. 3, operation means used for normal program viewing, for example, a channel change button for selecting a broadcast station. .

In this embodiment, the time shift reproduction operation is
At the start, each operation means shown in FIG. 3 can be used. During the time-shift reproduction, the user performs an operation of the time-shift reproduction, for example, changes the reproduction speed, pauses the reproduction, changes the reproduction point, and the like by using the operation unit of FIG.

When the time shift reproduction operation is started, the bar 310 extends to the left with time. The pointer 311 remains on the right side of the bar 309. When the “pause button” 303 is pressed during playback, the playback is paused. During playback stop, the bar 310 extends to the left over time, but the pointer 311 moves to the left over time. While playback is paused, press the "play button"
Pressing 05 resumes the reproduction again. The bar 310 extends to the left with time, and the pointer 311
9 stopped.

When the "return button" 302 is pressed during playback or during pause of playback, the playback point returns to the past for 5 seconds. At this time, the pointer 311 moves to the left by 5 seconds. However, the pointer 311 already has the bar 309
On the other hand, if it has reached the left end, it will not return to the past any longer.

During playback or while playback is paused,
When the “forward button” 304 is pressed, the playback point advances to the future for 5 seconds. At this time, the pointer 311 moves rightward for 5 seconds. However, the pointer 311 has already been moved to the bar 3
If it has reached the right end with respect to 09, it will not proceed any further.

When the "slow playback button" 307 is pressed during playback, the playback speed is reduced by 0.2. If the current playback speed is a constant speed (1.0 times speed), the playback speed decreases by 0.2 and changes to 0.8 times speed. Thereafter, each time the “slow playback button” 307 is pressed, the playback speed decreases by 0.2 and changes until it reaches at least 0.2 times the speed.

During playback, a "high-speed playback button" 30
Pressing 8 increases the playback speed by 0.2. If the current playback speed is a constant speed (1.0 times speed), the playback speed increases by 0.2 and changes to 1.2 times speed. Thereafter, each time the “high-speed playback button” 308 is pressed, the playback speed increases by 0.2 and changes until it reaches a maximum of 4.0 times speed.

If the "constant speed reproduction button" 306 is pressed when the reproduction speed is not constant speed (1.0 times speed), the reproduction speed returns to the constant speed (1.0 times speed).

When the pointer 311 is moved right and left during the reproduction, the reproduction point can be changed to an arbitrary point in the past or the future. However, the range in which the pointer 311 can move is limited to the range of the bar 310.

When the "end button" 301 is pressed during playback or during pause, time-shift playback is terminated.
Return to the normal program viewing state.

The above-mentioned reproduction operation is transmitted to the program reproduction means 3, and the program reproduction means 3 changes the reproduction speed,
The change of the reproduction point, the pause of the reproduction, and the like are executed.

The above operation is an example in the present embodiment, and any TV program viewing / listening device having a time shift reproduction function can be carried out in the same manner as in the present embodiment.

The value of the increase / decrease of the reproduction speed (0.2) in the “slow reproduction button” 307 and the “high-speed reproduction button” 308, the “back button” 302, and the “forward button”

This is an example of the content recorded when the “forward button” 304 is pressed in the state where the reproduction is being performed at a constant speed at 15:35:20 on June 10th. First, reproduction stop is temporarily recorded at the same time as the reproduction point. Next, the reproduction point is advanced to 5 seconds in the future, and the reproduction start is recorded. In this case, the time at the reproduction point is a time 5 seconds after the reproduction is stopped.

Thereafter, when the movement of the “pointer” 311 is completed, the reproduction start is recorded again. At this time, the reproduction speed does not change and remains at the original 1.0 times speed.

2. Process of Step 2 Step 2 is a process of obtaining a playback result which is a result of analyzing the playback state of the user during the time-shift playback based on the record of the playback operation. It starts when the user's operation content becomes “end of time shift reproduction”. This process is executed when the user ends the time-shift reproduction and shifts to the normal program viewing state.

FIG. 5 is a flowchart showing the algorithm of the processing in step 2. The processing will be described with reference to the drawings.

2-1. Description of Flowchart of Step 2 First, the processing of the reproduction speed obtaining means 18 is executed (Step S501). Through this processing, the user obtains the playback speed during time-shift playback. The details of the processing of the reproduction speed acquisition means 18 will be described later.

Next, the processing of the operation record rearranging means 20 is executed (step S502). In this process, the recorded contents of the operation storage device 15 are rearranged so that the times of the reproduction points are arranged in chronological order. The rearranged result is recorded in the operation storage device 15 again.

Subsequently, the processing of the reproduction range obtaining means 16 is executed (step S503). Through this processing, the user obtains the range actually reproduced during the time-shift reproduction. The details of the processing of the reproduction range acquisition unit 16 will be described later.

Finally, the processing of the number-of-reproductions obtaining means 17 is executed (step S504). Through this process, the number of times the user has repeatedly played back during time-shift playback is obtained. The details of the processing of the number-of-times-of-reproduction acquisition unit 17 will be described later.

The details of the processing in steps S501 to S504 constituting step 2 will be described below in the order of processing.

(1) Details of the Process of Step S501 (Playback Speed Acquisition Unit 18) FIG. 6 is a flowchart showing the algorithm of the process of the playback speed acquisition unit 18. Reproduction speed acquisition means 18
Calculates the playback speed during time-shift playback.

(1) -1. Description of Flowchart of Processing of Reproduction Speed Acquisition Unit 18 First, the variables VC1 and VC2 are initialized to 0 (step S601). However, the variable VC1 is an integrated value of the time of slow reproduction, and the variable VC2 is an integrated value of the time of high-speed reproduction. Next, one content recorded in the operation storage device 15 is read (step S602). At this time, the operation contents, the time of the reproduction point, and the reproduction speed are read. When the processing of step S602 is performed, it is determined whether or not reading has been completed to the end (step S603). If it has been already read from the operation storage device 15, that is, it cannot be read again. Otherwise, the process proceeds to step S608. In step S608, the variable V
The values of C1 and the variable VC2 are passed to the weight calculation means 19, and the processing of the reproduction speed acquisition means 18 ends. On the other hand, if not all data has been read from the operation storage device 15, that is, if data has been newly read, the process proceeds to step S60.
Proceed to 4.

In step S604, step S602
It is determined whether or not the playback speed read in the processing of (1) is greater than 0, and if it is greater than 0, the flow proceeds to step S609.
In step S609, the playback speed read in the process of step S602 is stored in a variable VC3, and the read time of the playback point is stored in a variable VC4. Then, the process returns to step S602 again. On the other hand, step S
If the reproduction speed is 0 in step 604, step S60
Go to 5. In step S605, the time of the reproduction point read in the processing in step S602 is stored in a variable VC5.

Next, it is determined whether or not the variable VC5 is 1.5 or more (step S606). If the variable VC3 is 1.5 or more, the process proceeds to step S610. Step S610
Then, the difference between the variable VC5 and the variable VC4 is calculated, and the difference is added to the variable VC2. Then, again, step S
It returns to the process of 602.

In step S606, the variable V
If C3 is less than 1.5, the process proceeds to step S607.
In step S607, it is further determined whether or not the variable VC3 is equal to or greater than 0.5, and if the variable VC3 is equal to or less than 0.5,
Proceed to step S611. In step S611, a difference between the variable VC5 and the variable VC4 is calculated, and the difference is calculated as the variable V
Add to C1. Then, the process returns to step S602 again. If the variable VC3 is larger than 0.5 in step S607, the process returns to step S602 again.

(1) -2. First, at step S601, the variables VC1 and VC2 are set to 0.
Initialize to Next, in step S602, the recorded contents of the operation storage device 15 are sequentially read from the top. Then, steps S604 to S607 and step S60
In the processing from 9 to S611, attention is paid to the reproduction speed of the read recorded content. If the playback speed is greater than 0, the playback speed is stored in a variable VC3, and the playback point time is stored in a variable VC3.
4 is stored. At this time, the variable VC4 is the reproduction speed VC
3 holds the time when the reproduction is started.

On the other hand, if the reproduction speed is 0, the reproduction point time is stored in the variable VC5. At this time, the variable VC5 holds the time when the reproduction at the reproduction speed VC3 has been completed. If the variable VC3 is equal to or greater than 1.5, (VC5-VC
4) is added to the variable VC2. This is the variable VC3
Holds the playback speed, if the value is 1.5 or more, it is considered that high-speed playback has been performed, and the playback time is set to the playback start time (variable VC4) and the playback end time (variable VC5).
And adds to the variable VC2 holding the integrated value of the time during which the high-speed reproduction was performed. If the variable VC3 is equal to or less than 0.5, (VC5-VC5
4) is added to the variable VC1. This is because when the variable VC3 is 0.5 or less, it is considered that slow reproduction has been performed, and the reproduction time is obtained from the difference between the reproduction start time (variable VC4) and the reproduction end time (variable VC5), and the slow reproduction is performed. Is added to the variable VC1 holding the integrated value of the elapsed time.

The above processing is repeated until there is no more data recorded in the operation storage device 15 in step S603, and the final variable VC1 is obtained in the processing in step S608.
And the value of the variable VC2 are output to the weight calculating means 19 as an integrated value of the time of slow reproduction and an integrated value of the time of high-speed reproduction during the time shift reproduction.

In the processing of the reproduction speed obtaining means 18, the reference values (0.5 and 1.5 in this embodiment) of the reproduction speed at the time of judging slow reproduction or high-speed reproduction are not necessarily this value. It is not necessary, and may be adjusted to another value according to the embodiment.

(3) -1. Description of Flowchart of Process of Reproduction Range Acquisition Unit 16 First, a variable VA1 and a variable VA2 are initialized to 0 (step S701). However, the variable VA1 is a value indicating the state of whether or not the reproduction has been performed, and the variable VA2 is an integrated value of the reproduction time. Next, one content recorded in the operation storage device 15 is read out (step S702). At this time, what is read out is the operation content, the time of the playback point, and the playback speed. When the process of step S702 is performed, it is determined whether or not reading has been completed to the end (step S703).
If all of the data has already been read from the operation storage device 15, that is, if the data cannot be read again,
Proceed to step S708.

In step S708, the value of the variable VA2 is output to the weight calculating means 19, and the reproduction range obtaining means 16
Is terminated. On the other hand, if not all data has been read from the operation storage device 15, that is, if data can be newly read, the process proceeds to step S704. In step S704, it is determined whether or not the playback speed read in the processing in step S702 is greater than 0. If the playback speed is greater than 0, the process proceeds to step S709, the value of the variable VA1 is incremented, and the process proceeds to step S706. Step S7
04, read in the process of step S702,
If the reproduction speed is 0, the process proceeds to step S705, decrements the value of the variable VA1, and proceeds to step S706.

In step S706, the variable VA1 is set to 0
It is determined whether or not the variable VA1 has changed from 0 to 1, and if the variable VA1 has changed from 0 to 1, the process proceeds to step S710, and the time of the reproduction point read out in the process of step S702 is set to the variable V1.
A3 is stored, and the process returns to step S702 again.
On the other hand, if the variable VA1 has not changed from 0 to 1 in step S706, the process proceeds to step S707.

In step S707, the variable VA1 is set to 1
It is determined whether or not the variable VA1 has changed from 0 to 1 and the process proceeds to step S711, where the time of the reproduction point read out in the process of step S702 is set to the variable V1.
A4 is stored, the difference between the variables VA4 and VA3 is calculated, the difference is added to the variable VA2, and the process returns to step S702 again. Step S707
In the case where the variable VA1 does not change from 0 to 1,
The process returns to step S702 again.

(3) -2. Description of Processing Content of Playback Range Acquisition Unit 16 First, in step S701, variables VA1 and VA2 are initialized to 0.

Next, in step S702, the recorded contents of the operation storage device 15 are read in order from the top. And
Steps S704 to S707 and steps S709 to
In step S711, attention is paid to the reproduction speed of the read recorded content. If the reproduction speed is greater than 0, the variable VA1 is added. The variable VA1 holds the number of times of reproduction of the reproduction point. If the playback speed is greater than 0, that location is where playback has started. If the playback speed is 0, the variable VA

FIG. 8 is a flowchart of the process performed by the number-of-reproductions acquisition unit 17.

(4) -1. Description of Flowchart of Process of Reproduction Number Acquisition Unit 17 First, the variables VB1 and VB2 are initialized to 0 (step S801). However, the variable VB1 is the number of times of repeated reproduction, and the variable VB2 is the maximum value of the number of times of repeated reproduction. Next, one content recorded in the operation storage device 15 is read (step S802). At this time, what is read out is the operation content, the time of the playback point, and the playback speed. When the processing in step S802 is performed, it is determined whether the stored contents have been read to the end (step S802).
803) If all data has already been read from the operation storage device 15, that is, if data cannot be newly read, the process proceeds to step S807.

In step S807, the value of the variable VB2 is output to the weight calculating means 19, and the reproduction number obtaining means 17
Is terminated. On the other hand, if not all data has been read from the operation storage device 15, that is, if data can be newly read, the process proceeds to step S804. In step S804, it is determined whether or not the playback speed read in the processing in step S802 is greater than 0. If the playback speed is greater than 0, the flow advances to step S808 to decrement the value of the variable VB1, and returns to the processing in step S802. In step S804, if the reproduction speed read in the process of step S802 is 0, the process proceeds to step S805,
The value of the variable VB1 is incremented, and step S806 is performed.
Proceed to.

In step S806, it is determined whether or not the variable VB1 is larger than the variable VB2. If the variable VB1 is larger than the variable VB2, the process proceeds to step S809, where the value of the variable VB1 is stored in VB2, and step S802 is performed again.
Return to the processing of. In step S806, the variable VB1
Is less than or equal to the variable VB2, the process returns to step S802.

(4) -2. Description of Processing by Reproduction Number Acquisition Unit 17 First, in step S801, variables VB1 and VB2 are initialized to zero.

Next, in step S802, the recorded contents of the operation storage device 15 are read sequentially from the head. And
Steps S804 to S806, steps S808, S8
At 09, attention is paid to the reproduction speed of the read recorded content.
If the reproduction speed is greater than 0, the value of the variable VB1 is incremented, and the variable VB1 and the variable VB2 are compared. When the variable VB1 is large, the value of the variable VB1 is
To be stored. If the reproduction speed is 0, the variable VB1 is decremented. The variable VB1 holds the number of times of reproduction of the reproduction point. If the playback speed is greater than 0, that location is where playback has started. Similarly, if the playback speed is 0
In the case of, the point is the point where the reproduction is completed. Variable V
B2 holds the maximum value of the variable VB1, and this value is the maximum value of the number of times of repeated reproduction in the reproduction range.

The above processing is repeated in step S803 until there is no more recorded content in the operation storage device 15. In the processing in step S807, the value of the variable VB2 is finally set to the number of times of repetition during time-shift reproduction. It is passed to the weight calculation means 19 as the maximum value.

In the present embodiment, the maximum value of the number of times of repetitive reproduction is used. However, as an implementation method, it is also possible to use the sum total of the number of repetitions for each place where repetitive reproduction is performed. .

3. Step 3 Step 3 is a process for calculating the degree of interest of the user based on the reproduction result obtained in step 2.
Is a process executed after step 2. FIG.
It is a flowchart figure which shows the algorithm of the process of step 3.

3-1. Description of Flowchart of Step 3 First, a variable VW1 is initialized to 0 (step S90).
1). However, the variable VX1 is the value of “weight”. Next, the record in the operation storage device 15 is read out, the time of “start of time shift reproduction” is stored in a variable VY1, the time of “end of time shift reproduction” is also obtained, and stored in a variable VY2 (step S902).

Next, the value of the variable VA2 is replaced by the variable VX1.
The value of the variable VB2, the value of the variable VC1,
The value of variable VC2 is stored in variable VX3, respectively, in variable VX4 (step S903). Then, (VX1 ×
100) / (VY2−VY1) to calculate the variable VW2
(Step S904).

Then, it is determined whether or not the value of the variable VW2 obtained in the processing of step S904 is 25% or more and less than 50% (step S905). If the value of the variable VW2 is 25% or more and less than 50%, Proceeding to step S908, the variable V
W1 is incremented, and the process proceeds to the next step S911. If the value of the variable VW2 is not equal to or more than 25% and less than 50%, the process proceeds to step S906, and furthermore, equal to or more than 50% and 75%.
% Is determined. In step S906, if the value of the variable VW2 is 50% or more and less than 75%,
Proceeding to step S909, the variable VW1 is incremented by 2 and then proceeding to the next step S911. If the value of the variable VW2 is not 50% or more and less than 75%, the process proceeds to step S907, and
It is determined whether it is 5% or more. In step S907, if the value of the variable VW2 is 75% or more, the process proceeds to step S907.
The process proceeds to 910, where 3 is added to the variable VW1, and similarly proceeds to step S911. If the value of the variable VW2 is not equal to or more than 75%, the process directly proceeds to step S911.

In step S911, the variable VX2 is added to the value of the variable VW1.

Thereafter, (VX3 × 100) / (VY2-
VY1) is calculated, the variable VZ1 is calculated, and (VX4 ×
100) / (VY2−VY1), and the variable VZ2
, And the variables VZ1 and VZ
Using (Z2), (VZ1−VZ2) / 20 is calculated, the result is rounded to an integer, and stored in the variable VZ3 (step S912). Next, the value of the variable VZ3 obtained in step S912 is added to the variable VW1 (step S913). Then, the value of variable VW1 obtained in step S913 is output to viewing program recording means 13, and step 3 ends.

3-2. Description of Processing in Step 3 First, in step S901, a variable VW1 indicating "weight" is set.
Is initialized to 0. Next, in step S902,
The time of “start of time shift reproduction” is obtained from the operation storage device 15 and stored in the variable VY1. Similarly, the time of "end of time shift reproduction" is also obtained and stored in the variable VY2.

Then, in step S903, step 2
Is stored in the following variables. In the process of step S708 (see FIG. 7), the time of the range actually reproduced during the time shift reproduction, which is stored in the variable VB2, is stored in the variable VX1. In the processing of step S807 (see FIG. 8), the maximum value of the number of times of repeated reproduction during the time-shift reproduction stored in the variable VB2 is set in the variable VX.
2 is stored. In the process of step S608 (see FIG. 6), the integrated value of the time during which the slow reproduction is performed during the time shift reproduction, which is stored in the variable VC1, is stored in the variable VX3. In the process of step S608, the integrated value of the time during which the slow reproduction is performed during the time shift reproduction, which is stored in the variable VC2, is stored in the variable VX4.

In the processing of step S904, (VX1 × 1
00) / (VY2-VY1) is calculated and stored in the variable VW2. The value of this variable VW2 indicates what percentage of the time subjected to the time shift reproduction was actually reproduced. For example, after starting the time-shift reproduction, the reproduction at the constant speed is performed for one minute, and then the operation of the pause is performed, and after the lapse of five minutes, the time-shift reproduction is completed. Is the target time of 6 minutes, but the actual playback time is 1 minute.

In steps S905 to S910, the variable VW
If 2 is not less than 25% and less than 50%, the variable VW1 is incremented. The variable VW2 is 50% or more and 7
If it is less than 5%, the variable VW1 is added by 2. And
If the variable VW2 is 75% or more, add 3 to the variable VW1. By this processing, the weight to be added is increased as the ratio of the actually reproduced data increases. However, the relationship between the reproduced ratio and the weight to be added does not necessarily need to be as in the present embodiment, and may be adjusted to another value according to the embodiment.

In step S911, the variable VX2 is added to the variable VX1. By this process, the weight to be added is increased as the number of times of repeated reproduction is larger. However, the method of directly adding the number of times of repeated playback to the weight is
It is not always necessary to make the same as in the present embodiment, and another method, for example, adjustment such as multiplying the magnification by several times may be performed according to the embodiment.

In step S912, (VX3 × 100)
/ (VY2-VY1) is calculated. This value indicates what percentage of the time during the time-shifted reproduction was slow-reproduced. However, since the variable VX3 is an integrated value, this value exceeds 100%. This calculation result is stored in a variable VZ1. Similarly, (VX4 × 10
0) / (VY2-VY1) is calculated. This value indicates what percentage of the entire time of the time-shifted reproduction has been reproduced at high speed. However, since the variable VX4 is an integrated value, this value exceeds 100%. This calculation result is stored in a variable VZ2. And (VZ1-VZ
2) Calculate / 20, convert the result to an integer, and store it in variable VZ3. By this process, the weight to be added increases as the rate of slow reproduction increases, and conversely, the weight to add decreases as the rate of high-speed reproduction increases. However, the formula for adding the reproduction speed to the weight does not necessarily need to be the same as that in the present embodiment, and may be adjusted according to another embodiment, for example, by multiplying the magnification by several times. Absent.

In step S913, the variable VZ3 is added to the variable VW1. Finally, in step S914, the value of the variable VW1 is passed to the viewing program recording means 13 and used as the value of the "weight" of the program.

In this embodiment, the reproduction range obtaining means 1
6, all three types of variables obtained from the number-of-reproductions acquisition unit 17 and the reproduction speed acquisition unit 18 are used as factors for determining the “weight” of the weight calculation unit 19, but it is not always necessary to use all of them at the same time. However, any one type or only two types may be adopted.

In this embodiment, the reproduction range obtaining means 1
6, weight calculation means 19 based on three types of results obtained from the number-of-reproductions obtaining means 17 and the reproduction speed obtaining means 18
In the above, the calculated “weight” is simply added and used as the “weight” of the program, but a more complicated method, for example, the number of times of repeated reproduction, the reproduction time of the range, Used together, the individual playing time is what percentage of the total
May be used as the “weight” of the program.

[0123]

According to the present invention, by using the operation history of the time shift reproduction operation, it is assumed that the user is actually watching the program in front of the TV program viewing apparatus during the time shift operation. As a result, a program watched using the time-shift playback function can be regarded as being definitely viewed by the user, and a recommended program based on the program is
What reflects the taste of the user can be provided.

Further, according to the present invention, the time-shift reproduction operation requires a more active operation for the user than the normal program viewing, so that the user has to spend much time for the operation. Then, only if you decide on your own,
Time shift playback is performed, and unless the user has a strong interest in the program, the time shift playback is not performed. Since it can be regarded as having been watched with interest, a recommended program based on the program can obtain a result reflecting the user's preference.

Further, according to the present invention, the purpose of the time-shift reproduction operation is to allow the user to actively watch the program, and to grasp the degree of interest in the viewed program by using the contents of the operation. This does not mean that the user is required to perform special operations for recommended functions, so if a user actively watches a program, he or she naturally understands the degree of interest in the viewed program. In addition to the fact that users need more active operations than normal program viewing, users rarely accidentally perform this operation on programs they are not interested in. Programs that are not interesting are not mistakenly considered interesting.

Therefore, as compared with the prior art, the present invention allows a user to select a program different from the user's preference even though the user does not need to perform any special operation for the recommended function. This prevents the user from erroneously assuming that the user is interested, and as a result, has the effect of greatly reducing the possibility of retrieving a program different from the user's preference and presenting it erroneously.
