Description

  The present invention relates to a content reproduction technique, and more particularly to a technique for reproducing content according to a viewing history.

  In recent years, with the development of communication technology, the same content can be obtained and enjoyed from various media. Taking a television (Television, hereinafter referred to as “TV”) as an example, in addition to TV, there are various types such as Internet distribution and digital versatile disc (hereinafter referred to as “DVD”). Can be viewed using various media. In addition, since a one-segment partial reception service (hereinafter referred to as “one-segment broadcasting”) for mobile phones and mobile terminals has been started, it is possible to view TV broadcast programs from compatible mobile terminals anytime and anywhere. Furthermore, since the recording of a long time has become possible due to the widespread use of hard disk drive (HDD) recorders, a method of recording a program of interest and making it into a library, and selecting and viewing the program from that library is becoming popular. . From this, it can be said that HDD recorders are frequently used as one of viewing media.

  Previously, content viewing methods were limited to those using a television receiver. In the case of a television broadcast program, since the broadcast time of the program that the user wants to watch is limited, a user who cannot view the television broadcast at this time missed the opportunity to view the program. However, at present, there are many means for viewing one program, and the user can view the program by using any one of them. As a result, it can be said that user convenience has improved in viewing the program. On the other hand, it can be said that it is creating a new inconvenience for the user in the sense that the user has increased the situation that a part that has already been viewed on one medium must be viewed again on another medium.

  For example, it is assumed that a user views the first half of a program that is a mobile phone by one-segment broadcasting and then views the same program on a storage medium such as a DVD. At that time, if the user feels that there is no need to view again the first half part that has already been viewed, the user may fast-forward the first half part.

  In this way, when a user who has already viewed a part of a program that is a medium views an unviewed part on another medium and changes the playback speed between the viewed part and the unviewed part, the user It is necessary to memorize the viewing history. Furthermore, in order to change the reproduction speed, the user needs to perform a complicated operation via a remote controller or the like. Such work is established when the user stores the viewed part, but otherwise the user unconsciously views the viewed part again. If the user does not want to watch the same part again, this is a waste of time.

As a means for solving such a problem, in Patent Document 1, a history of viewing by a user in the past is stored for a program stored in a storage medium such as a hard disk, and a viewing history for each program is displayed in a graph. A media playback device is disclosed. According to the technique disclosed in Patent Document 1, even if the user does not remember which part has been viewed, the user can confirm the part that has been viewed and the part that has not been viewed based on the viewing history displayed by the media playback device. It is supposed to be possible. For this reason, it is possible to avoid wasting time by repeatedly viewing the same portion.

  However, in Patent Document 1, a program for which a viewing history is created is limited to a program existing on a storage medium. As the storage medium, a hard disk (HD) included in the media playback device is assumed. In Patent Document 1, it is possible to create a viewing history for a program stored on a DVD that can be played back by a media playback device. However, the viewing history in various other media as described above is not supported. . For this reason, the viewing history when viewing the same program with a plurality of different media cannot be made at a glance.

  Further, also in the present technology, when the user changes the playback speed between the viewed part and the unviewed part, the user must perform this operation by himself.

  Therefore, the object of the present invention is to obtain a viewing history in which a watched part and an unviewed part are stored when playing back a program that the user has watched in the past, even if the utilization medium is different. It is to provide a broadcast program playback system.

  Another object of the present invention is to provide a broadcast program playback system capable of changing the playback speed of a program between a viewed part and an unviewed part without performing a cumbersome operation.

  The playback apparatus according to the first aspect of the present invention obtains a viewing history acquisition means for obtaining a viewing history specifying a non-viewing period and a viewing-completed period of a certain content, and a viewing history acquisition means among the certain contents. The first part associated with the non-viewing period at the first playback speed and the second part associated with the viewed period according to the non-viewing period and the viewed period specified by the viewed history Including a variable speed reproduction means for reproducing the video at a second reproduction speed different from the first reproduction speed.

  The viewing history acquisition means acquires the viewing history of the content. The viewing history specifies an unviewed period and a viewed period with respect to the time period from the start to the end of the content. The variable speed playback means uses, as a first part, a time period associated with an unviewed period among time periods from the start to the end of content, and a second period as a time period associated with a viewed period. . The speed variable playback means further plays back the first part and the second part at different playback speeds.

  The playback apparatus changes the playback speed of the content between the time period associated with the unviewed part and the time period associated with the viewed part. The user can enjoy the content at a reproduction speed corresponding to the viewing history without performing troublesome operations such as remote control operation.

  Preferably, one of the first and second speeds is a normal speed and the other is a fast forward playback speed that is faster than the normal speed.

  The playback apparatus plays back one of the time period associated with the non-viewing period and the time period associated with the viewed period at a normal speed and the other at a fast-forward speed. The user can enjoy one at a normal playback speed without performing any troublesome operations such as remote control, and the other can confirm the outline in a short time by fast-forward playback.

  Preferably, one of the first and second portions that is played back at a normal speed by the variable speed playback means is a portion that matches one of the unviewed period and the watched period specified by the viewing history. The other part of the non-viewing period and the viewed period is a part of a predetermined time adjacent to the matching part, and the other part of the first and second parts is specified by the viewing history. And a portion corresponding to the other of the unviewed period and the viewed period, and a portion excluding the predetermined time portion.

  In this playback apparatus, a portion of the content that is played back at a normal speed is a predetermined period adjacent to one of the unviewed period and the watched period and the other period. It is a period combined with the time period. The part other than the part that is played back at the normal speed is played back at the fast forward speed.

  In this playback apparatus, based on the viewing history, a part of the content is played back at a normal speed and the other part is played back at a fast-forward speed. In such skip reproduction, the user cannot understand in detail the content of the portion reproduced at the fast-forward speed. For this reason, it may be difficult for the user to grasp the entire content. As an improvement measure for this, the present playback device expands the portion of normal speed playback classified based on the viewing history in the content around a predetermined time. As a result, the fast-forward speed reproduction portion is shortened, and the normal-speed reproduction portion that can be understood in detail is expanded. As a result, the user can grasp the content contents more easily.

  Preferably, the first and second portions respectively match one and the other of the unviewed period and the viewed period specified by the viewing history.

  In this playback apparatus, one of the non-viewing period and the viewing period is played at a normal speed, and the other is played at a fast-forward speed. One can be enjoyed at a normal playback speed, and the other can be confirmed in a short time by fast-forward playback.

  A content reproduction system according to a second aspect of the present invention includes a content receiving unit for receiving broadcast or distributed content, and a reproducing unit for reproducing the content received by the content receiving unit in accordance with a user instruction. And a viewing history creation means for creating a viewing history for specifying a viewing period and a non-viewing period of the content according to the progress of playback of the content by the playing means, and a viewing history created by the viewing history creation means, Obtained by the receiving apparatus, the viewing history obtaining means for obtaining the viewing history from the receiving apparatus, and the viewing history obtaining means, including an output means for outputting the content corresponding to the viewing history together with information for identifying the content. Among the contents corresponding to the viewing history, the non-viewing period and viewing specified by the viewing history Depending on the period, the first part associated with the non-viewing period is at the first reproduction speed, and the second part associated with the viewed period is at the second reproduction speed different from the first reproduction speed. And a playback device including variable speed playback means for playback.

  In the content reproduction system, the reception device reproduces content received by broadcasting, distribution, or the like according to a user instruction.

The created viewing history is output to the playback device together with information for identifying the corresponding content. The playback device plays back the corresponding content based on the content identification information included in the obtained viewing history. In playback, the variable speed playback means uses a first time period, which is a time period associated with an unviewed part, of the content based on the viewing history, and a time period associated with the viewed part at the first playback speed. Are reproduced at the second reproduction speed.

  When the content is played back by the playback device, the playback device can obtain the viewing history in which the viewed portion and the unviewed portion are stored by receiving the output from the receiving device. The playback device changes the playback speed of the content between the time period associated with the unviewed part and the time period associated with the viewed part. For this reason, it is possible to change the playback speed of the program between the viewed part and the unviewed part without a troublesome operation by the user.

After step 410, the viewing time of each viewing history in the selected viewing history set Are all less than 30 seconds, and the flow of control branches according to the determination result. In step 412, in the set of viewing history selected in step 412, all of the viewing times are not less than 30 seconds. Is executed in response to the determination, and by deleting the viewing history having a viewing time of less than 30 seconds from the viewing history group, , And after the step 414, and in response to the determination that one viewing time is all less than 30 seconds in the step 412, the original viewing history before correction And step 416 which returns control to step 318 of FIG.

  14, FIG. 15, FIG. 18, and FIG. 19 are flowcharts showing the control structure of the program playback program executed by the control unit 160 in the playback apparatus 150 shown in FIG.

  Referring to FIG. 14, the program for main control of program playback executed by control unit 160 determines whether or not viewing history display button 162 shown in FIG. 5 is turned on by the user and power to playback device 150 is turned on. It includes step 430 of determining and waiting until the viewing history display button 162 is turned on.

  Referring to FIG. 15, this program is further executed in response to determining that viewing history display button 162 is turned on in step 430 shown in FIG. 14, and the power of display unit 170 shown in FIG. After step 440 and step 440, it is determined whether or not the viewing data file 340 shown in FIG. 10 exists in the external input device 168 shown in FIG. 5, and the control flow branches according to the determination result Step 442.

  In step 442, an external storage device capable of inputting information is connected to the external input device 168, and a viewing data file that can be read by the playback device 150 in the information stored in the connected external storage device. If 340 exists, the determination result is YES, otherwise NO.

  This program is further executed in response to the determination that the viewing data file 340 exists in the external input device 168 in step 442, and the viewing history screen and playback section information to be described later based on the viewing data file 340. After step 444, after step 444, step 446 for displaying the viewing history screen on the display unit 170 shown in FIG. 5, and after step 446, the user selects a program to be played back from the viewing history screen being displayed. In step 448 for branching the flow of control according to the determination result and in step 448, the program is executed in response to selection of the program to be played back and connected to the external input device 168. Of the information stored in the external storage device, information on the selected program is searched based on the EPG information. 450 and after step 450, it is determined whether there is reproducible data in the information related to the program detected by the search, and the flow of control is branched according to the determination result. And step 454, which is executed in response to the determination that there is no reproducible data in step 452, and causes the display unit 170 to display that there is no corresponding data.

  In step 452, if the detected information includes data from the start to the end of the program and EPG information, the determination result is YES, otherwise NO is determined.

  This program is further executed in response to the determination in step 448 that the program to be played back has not been selected, and it is determined whether or not the viewing history display button 162 has been turned off by the user. In response, step 455 for branching the control flow is included. If it is determined in step 455 that the viewing history display button 162 has been turned off, the process proceeds to step 460 described later, and if not, the process returns to step 448.

  The program is further executed in response to the determination that the viewing data file 340 does not exist in the external input device 168 in step 442, and the display unit 170 displays that there is no viewing history; After step 454 and step 456, it is determined that the viewing history display button 162 is turned off by the user and the standby history display button 162 is turned off in step 458 in which the user waits until the playback apparatus 150 is turned off. Step 460 is executed in response to this, and the process returns to Step 430 shown in FIG.

  FIG. 16 shows an example of a viewing history screen 480 that is created in step 444 in FIG. 15 and is displayed in step 446 and that allows the user to select a program to be played back. Referring to FIG. 16, viewing history screen 480 is created based on viewing data file 340 shown in FIG. For example, the history 485 is created based on the record 350 shown in FIG. The main data of this data is the viewing history shown in the row 147 shown in FIG.

  FIG. 17 schematically shows the playback section information created in step 444 shown in FIG. 15 based on the record 350 shown in FIG. 15 for the viewing history shown in the row 147 shown in FIG. The playback section information is created in order to change the playback speed between the viewed part and the unviewed part during playback. Referring to FIG. 17, in the playback section information, a time period from the start to the end of the program is represented by a band 490. The band 490 is divided into a viewed part and an unviewed part. In the band 490, the left end indicates the start time 0:00 of the program, and the right end indicates the end time 1:00 of the program. The program has a broadcast time of 1 hour, and the broadcast time = 1: 00: 00. In this viewing history, the user views the program for three different time periods. For each viewing history, a data set 496 indicates a viewing start time, and a data set 498 indicates a viewing end time. In the example shown in FIG. 17, 6 minutes and 20 seconds from the start of the program, 7 minutes and 30 seconds to 8 minutes after the start, and 8 minutes and 20 seconds to 1 hour after the start Part.

  Referring to FIG. 18, this program is further executed in response to the determination that there is reproducible data in step 452 shown in FIG. 15, and a variable indicating the number of data processed in the following steps. Step 500 for substituting the number of viewing start times into M, and after step 500, the playback start time data is read out as an array of M data from the playback section information created in step 444 shown in FIG. After step 502 and step 502, the data of the viewing end time is read from the playback section information as M data arrays, and after step 504, a variable i indicating the number of processed viewing histories is set to zero. And 506 for substituting.

  Referring to FIG. 19, after step 506, the program further sets step 510 for setting the speed at which the program is played back to the normal speed, and after step 510, the program is played back to playback unit 166 shown in FIG. And step 514 after step 512 for determining whether or not broadcast time ≦ T with respect to the broadcast time of the program, where T is the elapsed time from the beginning of the program. In step 514, when the program is reproduced to the end, the broadcast time ≦ T, and the determination result is YES. On the other hand, if not, NO is determined.

  The program further includes a step 516 that is executed in response to the determination that the broadcast time ≦ T in step 514, and causes the playback unit 166 to stop playback. After step 516, processing returns to step 446 shown in FIG.

  The program is further executed when the determination result in step 514 is NO, and whether the elapsed time T is start [i] = T with respect to the viewing start time “start [i]” of the i-th viewing history. Step 518 for determining whether or not, Step 520 executed in response to the determination that start [i] = T in Step 518 and changing the playback speed to double speed, and Step 520, And it is executed in response to the determination that it is not start [i] = T in step 518, and the elapsed time T is the end [i] = T with respect to the i-th viewing end time “end [i]”. And step 522 executed in response to determining that the end [i] = T in step 522 and changing the playback speed to the normal speed.

  In step 518, when the elapsed time T has reached the viewing start time of any viewing history, the determination result is YES. This means that the playback section has changed from the unviewed part to the viewed part. In this case, the playback speed changes from normal to double speed. In step 522, if the elapsed time T reaches the viewing end time of any viewing history, the determination result is YES. This means that the playback section has changed from the viewed part to the unviewed part. In this case, the reproduction speed changes from the double speed to the normal speed.

  The program is further executed after step 524 in response to determining that i <M in step 526, and in step 526, i <M. And step 530 that determines whether or not the elapsed time T has been counted up after step 528 and waits until the elapsed time T is counted up. If it is determined in step 530 that the elapsed time T has been counted up, the process returns to step 514. If it is determined in step 522 that the end [i] = T is not satisfied, and if it is determined in step 526 that i <M is not satisfied, the process proceeds to step 530.

  If there is a viewing history that has not been processed in step 524, i <M, and the determination result is YES. Further, when the double-speed playback processing is completed for all the viewed portions of the viewing history, i = M and the determination result is NO.

-Operation-
The broadcast program playback system whose configuration has been described above operates as follows.

  The operation of the mobile TV 110 with a telephone function will be described.

  Referring to FIG. 3, when power to portable telephone 110 with a telephone function is turned on by viewing button 126, control unit 124 is stored in recording unit 134, as shown in FIGS. 6 to 9 and FIGS. 11 to 13. The program having the control structure shown in FIG. After the power is turned on, the antenna 120, the TV receiving unit 122, the EPG storage unit 132, the external output device 136, and the display unit 138 perform predetermined operations according to the control of the control unit 124 by the initial setting.

  Since the viewing button 126 is turned on when the power is turned on, the control unit 124 determines YES in step 190 shown in FIG. 6, controls the TV receiving unit 122, and transmits the signal of the channel set by the initial setting. Start receiving. Here, as an initial setting, it is assumed that the signal of the channel received before the power is turned on is received again. The TV receiver 122 changes the frequency setting to receive the set channel, receives a signal via the antenna 120, waits for tuning at the new frequency, and demodulates this signal. The TV receiver 122 further separates the demodulated signal packet according to its type. The signal is separated into a program specific information / service information packet, a video signal packet, and an audio signal packet. The TV receiving unit 122 further performs processing for converting the information included in the video signal packet and the audio signal packet into a format that can be output as video and audio, and sends the video signal to the display unit 138. Output to a speaker (not shown).

  The TV receiving unit 122 outputs EPG information among the information included in the program identification information / service information packet to the EPG storage unit 132 via the control unit 124. The EPG storage unit 132 stores the EPG information received from the TV receiving unit 122. Other information included in the program specific information / service information packet is stored in the recording unit 134.

  In step 210 of FIG. 7, the control unit 124 turns on the power of the display unit 138 so that the video signal can be displayed. In step 212, the control unit 124 clears the viewing history table 140 shown in FIG. 4 stored in the recording unit 134 and all viewing histories included therein. At this time, the viewing history table 140 to be cleared was created when the portable TV 110 with telephone function was turned on and the program was viewed last time. In step 214, it is determined whether or not there is a viewing history for the currently received program in the viewing history table 140 stored in the recording unit 134.

  Here, since the viewing history table 140 and the corresponding viewing history do not exist in the recording unit 134, the determination result in step 214 is NO. In steps 218, 220, and 222, the control unit 124 controls the recording unit 134 to create the viewing history table 140, which is a program scheduled to be displayed, and is currently being broadcast on the channel being received by the mobile TV 110 with a telephone function. For the program, a viewing history is created in the viewing history table 140 based on the EPG information related to the program based on the information accumulated in the EPG storage unit 132, the other information stored in the recording unit 134, and the viewing start time.

  The EPG information is received together with the video signal of the channel while receiving the broadcast signal. The EPG information of other channels not received is received from all broadcasting stations by the TV receiving unit 122 when the mobile TV 110 with telephone function is turned off and is in a standby state, and stored in the EPG storage unit 132. Is done.

  In step 224, the control unit 124 displays the video signal of the program being broadcast on the channel being received on the display unit 138.

  When the broadcast of the program being displayed has ended, the determination result in step 226 is YES, and in step 290 shown in FIG. 8, the control unit 124 adds the generated viewing history of the program as the viewing end time at the time of processing. Add time.

  If there is no instruction from the user thereafter, the same channel is received, and the user views a program being broadcast on that channel. This program has not been viewed, and the viewing history of this program does not exist in the viewing history table 140 in the recording unit 134. Therefore, the viewing history creation process in steps 214, 216, 218, 220, 222, 224, 226, and 290 is repeated for each program until an instruction is given.

  If the program is being broadcast but there is any interruption, the determination result in step 228 shown in FIG. 7 is YES, and the control unit 124 executes the program having the control structure shown in FIG.

  When the interruption is an incoming call by the telephone function, and the user gives an instruction to switch the function of the portable TV 110 with the telephone function from the TV function to the telephone function by operating the TV / phone switching unit 130, the control unit 124 In steps 362 and 364 shown in FIG. 11, switching to the telephone function, addition of the viewing end time to the viewing history, and storage in the recording unit 134 of the viewing history table 140 including the viewing history are performed. The user starts and continues the call at step 366. In steps 368 and 370, the control unit 124 waits until the user instructs the end of the call. When the user instructs the end of the call, the control unit 124 controls the TV / phone switching unit 130 to change the function of the portable TV 110 with a telephone function to the TV function. Switch to. At this time, the process returns to step 214 shown in FIG. 7, and a new viewing history is created. On the other hand, if the user has not received an instruction to switch from the TV function to the telephone function even after receiving an incoming call, the process returns to step 224 shown in FIG. 7, and the output of the program that has been viewed up to now is continued.

  If the interruption is TV channel switching, the control unit 124 adds the viewing end time to the viewing history of the program that was being viewed until the channel switching instruction is received in step 390 of FIG. A viewing history table 140 including the viewing history is stored. In step 392, the control unit 124 controls the TV receiving unit 122 to receive the channel designated by the user input to the channel switching unit 128. Processing returns to step 214 in FIG.

  If the channel switching is switching to a channel that has been viewed after the portable TV 110 with telephone function is turned on, and the program being broadcast on the channel has also been viewed, the determination result in step 214 is YES. Become. In this case, in step 222, the viewing start time is added to the already created viewing history. Otherwise, the determination result in step 214 is NO, and in step 216, the viewing history of the program to be viewed is created in the viewing history table 140. After step 218, the same operation as that immediately after the power is turned on is executed.

  When the interruption is an instruction to turn off the viewing button 126 by the user, the control unit 124 adds the viewing end time to the viewing history in the viewing history table 140 in step 316 in FIG. A viewing history table 140 including a history is stored. The process proceeds to step 318, step 410 shown in FIG. The control unit 124 corrects the zapping in the viewing history. The correction method will be described below by taking the contents of the viewing history table 140 shown in FIG. 4 as an example.

  Of the viewing histories grouped for each program stored in the viewing history table 140 in step 410, No. Choose the largest one. Here, the viewing history set No. 6 corresponds to this. In steps 412, 414, and 416, the control unit 124 newly creates a modified viewing history for each viewing history included in the selected viewing history set whose viewing time is 30 seconds or more. Viewing history No. In the case of 6, since the viewing time at the first viewing time is 17 seconds, a modified viewing history is not created, and a modified viewing history is created for a viewing history of one hour viewed later and stored in the recording unit 134. . After this processing, the original viewing history set is deleted, whereby the first viewing history is deleted from the recording unit 134. Processing proceeds to step 318 shown in FIG. If there is a viewing history set that has not been corrected, the process proceeds again to step 410 shown in FIG. 13, and the correction process is repeated until all viewing history sets included in the viewing history table 140 have been corrected.

  In the case of the viewing history table 140 shown in FIG. 3, no. 4 and no. The viewing history set of 5 is deleted in the processing of step 416 because the viewing time of the viewing history included in these is all less than 30 seconds.

  After creating the modified viewing history table by the modification process described above, the control unit 124 creates the viewing data file 340 shown in FIG. 10 in step 320 shown in FIG. The control unit 124 saves the created viewing data file 340 in the external storage device connected to the external output device 136 in the processing of step 322 and the subsequent steps, and then turns off the power of the display unit 138 and the mobile TV 110 with telephone function. Turn off the power. When the external storage device is not connected to the external output device 136, the control unit 124 displays that fact on the display unit 138 and waits until the external storage device is connected.

  Next, the operation of the playback device 150 will be described.

  Referring to FIG. 5, when playback device 150 is turned on by viewing history display button 162, control unit 160 is stored in recording unit 164, as shown in FIGS. 14, 15, 18, and 19. The execution of the program having the control structure is started. After the power is turned on, the reproduction unit 166, the external input device 168, and the display unit 170 perform predetermined operations according to the control of the control unit 160 by the initial setting.

  Since the viewing history display button 162 is ON, the determination result of step 430 shown in FIG. 14 is YES. In step 440 shown in FIG. 15, the control unit 160 turns on the power of the display unit 170 so that the video signal of the program to be reproduced can be displayed. Here, the flow of control branches depending on whether or not the viewing data file 340 shown in FIG. 10 exists in the external input device 168. When the viewing data file 340 exists in the external input device 168, the program specified by the user is played as will be described below. If there is no viewing data file 340, a message to that effect is displayed and the viewing history display button 162 is turned off. Wait until it is done.

  If the viewing data file 340 exists in the external input device 168, the control unit 160 displays the viewing history screen 480 shown in FIG. 16 and the playback section information shown in FIG. 17 based on the viewing data file 340 in steps 444 and 446. The viewing history screen 480 is displayed on the display unit 170. When the user selects a program to be reproduced from the displayed viewing history screen 480, in step 450 of FIG. 15, the control unit 160 selects an EPG from the information stored in the external storage device connected to the external input device 168. Search for the selected program based on the information. This search is executed by comparing the ID information for identifying the program included in the EPG information in the viewing data file 340 with the ID information attached to the stored program data. When reproducible data is stored in the external storage device, the control unit 160 causes the playback unit 166 to change the playback speed between the viewed portion and the unviewed portion in the processing of step 500 and subsequent steps shown in FIG. Control and execute program playback.

  In order to describe the following processing, it is assumed that the user selects history 485 from viewing history screen 480 shown in FIG. The reproduction process is performed based on the reproduction section information of the history 485 shown in FIG.

  In steps 500, 502, 504, and 506 shown in FIG. 18, the control unit 160 performs the following processing. Substituting 3 as the number of viewing start times stored in the playback section information into the number M of data to be played back, M = 3. Three pieces of data of the viewing start time are read out from 0:00 to 10:00, which is the program broadcast time, and “start [1] = 0: 00: 00, start [2] = 0: 07:30, start [3] = 0: 08: 20 ". Similarly, three pieces of viewing end data are read out to obtain an array of “end [1] = 0: 06: 20, end [2] = 0: 08: 0, end [3] = 1: 00: 00”. 0 is substituted into the number i of processed data for the program reproduction program, and i = 0.

  In steps 510 and 512 shown in FIG. 19, the control unit 160 controls the reproduction unit 166 to start program reproduction at the normal speed. After that, the control unit 160 measures the time from the start of program reproduction, measures the elapsed time T from the start of the program at the time when each process is performed thereafter, and performs the process by comparing the value of T with the viewing start data and end data. Do.

  When the watched part is reached during the program playback, the control unit 160 changes the playback speed to double speed and continues this until the watched part ends and becomes an unviewed part. When the unviewed part is reached, the playback speed is returned to the normal speed. The reproduction speed is changed to double speed when reproduction progresses and the elapsed time T becomes the same as the viewing start time of each viewing history, that is, when the determination result in step 518 is YES, in step 520 This is executed by changing the playback speed. The playback speed is changed to the normal speed when the elapsed time T becomes the same as the viewing end time of the viewing history, that is, when the determination result in step 522 is YES, the playback speed is changed in step 524. To be executed. When the processing in steps 518, 520, 522, and 524 is executed, reproduction of one viewed portion at the double speed is completed, and one viewing history processing that requires processing is completed. Here, in the case where there are other watched parts to be reproduced, in step 528, the control unit 160 adds 1 to i and continues the process. On the other hand, if the playback of all the viewed parts has been completed, the determination result in step 526 is NO.

  Thereafter, when the reproduction is executed smoothly, the determination result in step 530 is YES, and the reproduction is continued until the program end time. When the reproduction up to the program end time ends and the broadcast time ≦ T, the control unit 160 controls the reproduction unit 166 to stop the reproduction in steps 514 and 516. If the T count does not increase with the passage of time due to some cause, the control unit 160 waits until an instruction from the user is given in step 530.

  Thus, in the broadcast program playback system according to the present embodiment, even when the user views the same program using different media, only the unviewed part can be enjoyed at the normal speed based on the viewing history. . At this time, the user does not have to store the viewing history by himself / herself. Furthermore, the user does not need to change the playback speed by a complicated operation such as a remote control operation.

  In the following embodiment, when the playback device 150 plays back a program that has been partly viewed, the operation and effect are the same as in this embodiment except for the time period for changing the playback time and the playback speed to be changed. Since it is similar, the description of the same part will not be repeated.

[Second Embodiment]
In the broadcast program playback system according to the second embodiment, at the time of program playback, the watched portion is played at a normal speed and the unviewed portion is played at a double speed.

  The technology according to the present embodiment satisfies the user's request that the part that has been viewed is viewed in detail, and only the outline is required for the part that has not been viewed. For example, there is a motivation such as introducing a program viewed by a user to a friend and explaining a portion of the viewed portion to which the user is interested.

  FIGS. 1C and 1D show a playback function sequence by the broadcast program playback system according to the second embodiment. Referring to FIG. 1, as shown in viewing history 30 in (C), the user has watched a certain program, but has watched periods 42 and 46, and has not watched other periods 40, 44, and 48. Suppose. Thereafter, the user sends the recorded program data and viewing history to a friend, and the friend tries to view the program. At this time, the broadcast program playback system according to the second embodiment plays back at the normal speed for the viewed period and at the double speed for the unviewed period, as shown in the playback method 64 in (D). . The user's friend does not need to perform complicated operations such as fast-forward playback during the viewed period by operating the remote controller.

  In the following embodiment, except for a part of the program having the control structure shown in FIG. 19, the configuration and operation are the same as those in the first embodiment. Therefore, description thereof will not be repeated.

−Configuration−
FIG. 20 is a flowchart for changing the playback speed, which is executed by the control unit 160 in the playback apparatus 150. The program whose control structure is shown in FIG. 20 is the same as the program used in the first embodiment shown in FIG. However, the program showing the control structure shown in FIG. 20 performs the same processing as these steps in place of steps 510 and 524 shown in FIG. 19, but steps 540 and 544 for setting the playback speed to double speed instead of the normal speed. 19 is different from the program having the control structure shown in FIG. 19 in that, instead of step 520 shown in FIG. 19, a step 542 in which the playback speed is set to the normal speed instead of the double speed is included.

-Operation-
In the program playback by the broadcast program system described above, the creation of the viewing history in the portable TV 110 with telephone function, the search of program data in the playback device 150, the acquisition of viewing history, and the acquisition of playback section information are as follows. As in the first embodiment, the program is executed by a program whose control structure is shown in FIGS. 6 to 9, 11 to 13, 14, 15 and 18.

  Referring to FIG. 5, in playback device 150, control unit 160 controls playback unit 166 to play back a program at double speed in steps 540 and 512 shown in FIG. 20 after step 506 shown in FIG. Start. Thereafter, the control unit 160 measures time from the start of program reproduction, and measures the elapsed time T from the start of the program at the time when each process is performed thereafter. The value of T, the viewing start data stored in the recording unit 164 and the end Processing is performed by comparison with data.

  When the watched part is reached during program playback, the control unit 160 changes the playback speed to the normal speed and continues this until the watched part ends and becomes an unviewed part. When the unviewed part is reached, the playback speed is returned to double speed. The playback speed is changed to the normal speed when the playback progresses and the elapsed time T becomes the same as the viewing start time of each viewing history, that is, when the determination result in step 518 is YES, the playback is performed in step 542. It is executed by changing the speed. In addition, when the elapsed time T becomes the same as the viewing end time of the viewing history, that is, when the determination result in step 522 is YES, the playback speed is changed in step 544. It is executed by being changed. When the processing in steps 518, 542, 522, and 544 is executed, the reproduction of one viewed portion at the normal speed is completed, and one viewing history processing that needs to be processed is completed. The subsequent processing is the same as in the first embodiment.

[Third Embodiment]
The broadcast program playback system according to the third embodiment is the same as that of the second embodiment, but at the time of program playback, playback is performed at a normal speed for five minutes before and after the viewed portion, as with the viewed portion. This is different from the second embodiment in that it is performed.

  With the technology according to the present embodiment, when a friend uses the user's viewing history to play the program, the friend can check in detail before and after the user's viewed portion. With this technology, for example, a friend may be able to find a part related to a part that the user missed.

  FIG. 1 shows a playback function sequence by the broadcast program playback system according to the third embodiment. Referring to FIG. 1, as shown in viewing history 30 in (C), the user has watched a certain program, but has watched periods 42 and 46, and has not watched other periods 40, 44, and 48. Suppose. Thereafter, the user transmits the viewing history to a friend, and the friend tries to view the same program based on the viewing history. At this time, as shown in the playback method 66 of (E), the broadcast program playback system according to the third embodiment is at a normal speed for the viewed period and for 5 minutes before and after that, and doubles for the unviewed period. Play at each speed. Since the unviewed periods 44 and 48 are included in the five minutes before and after the viewed period, they are reproduced at the normal speed.

  In the following embodiment, the configuration and operation are the same as those in the first embodiment except for the program executed in response to the determination of YES in step 452 shown in FIG. Therefore, description thereof will not be repeated.

−Configuration−
FIGS. 21 and 23 are flowcharts for correcting the playback section, which is executed by the control unit 160 in the playback device 150.

  Referring to FIG. 21, this program is executed in response to the determination that control unit 160 determines YES in step 452 shown in FIG. 15, and is similar to steps 500, 502, 504, and 506 shown in FIG. Steps 500, 502, 504 and 506 are performed.

  The program further sets, after step 506, the number of data for which the playback section has been corrected to i, and 5 minutes from the viewing start time “start [0]” in the first viewing history where i = 0. Step 560 for determining whether or not the previous time point is after the start time of the program, that is, whether or not start [0] -300> 0, and branching the control flow according to the determination result; 560 is executed in response to the determination that start [0] −300> 0, and the time 5 minutes before the actual viewing start time in the first viewing history is assigned to “start [0]”. Are executed in response to the determination that start [0] −300> 0 is not satisfied in step 560, and step 564 for substituting 0 for “start [0]”, steps 562 and 5 After 4, and a step 566 of adding 1 to i.

  In steps 560, 562, and 564, a process of correcting the playback section as a viewed portion is performed for a portion of the first viewing history that is five minutes before the viewing start time. When the viewing start time is less than 5 minutes, the viewing start time is 0:00. Otherwise, the viewing start time is corrected to a time 5 minutes before the actual viewing start time.

  The program further determines after step 566 whether or not i <M, and in step 568 for branching the control flow according to the determination result, and in step 568, it is determined that i <M. In response, the time point 5 minutes before the viewing start time “start [i]” in the i-th viewing history to be executed and processed is the (i−1) viewing end time “end [ i−1] ”, that is, whether or not start [i] −300> end [i−1] is determined, and the flow of control is branched in accordance with the determination result 570. In step 570, the process is executed in response to the determination that start [i] -300> end [i-1], and is a time 5 minutes before the actual viewing start time in the i-th viewing history. Substituting for “start [i]” After step 572 and step 572, 1 is added to i and then control is returned to step 568. In step 574 and step 570, it is determined that start [i] -300> end [i-1] is not satisfied. Step 576 is executed in response to this and deletes “start [i]” and “end [i−1]”, and after step 576, subtracts 1 from M and returns control to step 568. 578.

  In steps 566, 568, 570, 572, 574, 576, and 578, a process of correcting the reproduction classification as a viewed part is performed for a part of the i-th viewing history that is five minutes before the viewing start time. If the difference between the viewing start time and the viewing end time of the (i-1) th viewing history is less than 5 minutes, the i-th and (i-1) th viewing histories are corrected to one viewing history. Otherwise, the viewing start time is corrected to a time 5 minutes before the stored time.

  FIG. 22 shows the reproduction section information shown in FIG. 17 corrected by the program processing shown in FIG. Referring to FIG. 22, data set 600 is a viewing start time stored in viewing data file 340, and data set 602 is a viewing end time. All bands 590 indicating the playback section information after correction are viewed portions.

  Referring to FIG. 23, the program is further executed in response to the determination that i <M is not satisfied in step 568, and after step 610 for substituting M−1 for i, “end” It is determined whether or not the time point 5 minutes after [M-1] is later than the broadcast end time of the program, that is, whether or not [M-1] +300> broadcast time. Step 612 branches the control flow according to the result, and is executed in response to the determination that the end [M−1] +300> the broadcast time in step 612, and “end [M−1]”. In step 613 for substituting the broadcast time, and in step 612, it is executed in response to the determination that it is not the end [M-1] +300> broadcast time. 5 minutes of end time A step 614 that assigns a time, after step 613 and 614, and a step 616 subtracts 1 from the i.

  When the correction process proceeds and the correction of the viewing start time of the M viewing histories is completed, i = M and NO is determined in step 568. In subsequent steps 610, 612, 613, 614 and 616, by setting i = M−1, the viewing end time of the Mth, that is, the last viewing history is corrected. When the difference between the viewing end time and the broadcast time of the program is less than 5 minutes, the viewing end time is corrected as broadcast time. Otherwise, the viewing end time is corrected to a time 5 minutes after the stored time.

  The program further determines whether or not i ≧ 0 after step 616 and branches the control flow according to the determination result, and it is determined that i ≧ 0 in step 618. And the time point 5 minutes after the viewing end time “end [i]” of the i-th viewing history is the viewing start time “start [i + 1]” after correction of the (i + 1) -th viewing history. It is determined whether or not it is before the point of time, that is, whether or not end [i] +300 <start [i + 1], and the flow of control is branched according to the determination result, and in step 620, the end [i] Step 622 is executed in response to the determination that +300 <start [i + 1], and substituting the time after 5 minutes of the actual viewing end time in the i-th viewing history for end [i], 62 In step 624, which is executed in response to the determination that end [i] +300 <start [i + 1] is not satisfied, and deletes start [i + 1] and end [i], and after step 622 and step 624, Step 626 which subtracts 1 from i and returns the processing to Step 618 and Step 628 which is executed in response to the determination that i ≧ 0 is not satisfied in Step 618 and sets i = 0. After step 628, processing proceeds to step 540 shown in FIG.

  In steps 620, 622, 624, and 626, the viewing end time of the i-th viewing history is corrected. If the difference between the viewing end time and the viewing start time after correction of the (i + 1) th viewing history is less than 5 minutes, the i-th and (i + 1) th viewing histories are corrected to one viewing history.

  When all the corrections of the viewing start time and the viewing end time are completed, the process proceeds to step 628 and subsequent steps, and the program reproduction program shown in FIG. 20 is executed.
