A technique for neglecting this has been proposed (Patent Document 1).

JP 2003-274344 A

  Video playback devices, such as video decks, play TV programs and videos that have been recorded in the past, without considering anything even if the playback time is important, such as news programs or program previews. It was. Therefore, the user had to always be aware that it is a video. Recently, a recording apparatus having a large-capacity recording unit has become widespread, and a large number of programs can be recorded for a long time, so that the user can easily enjoy the recorded program. This makes it difficult to distinguish whether the program is a past program or a program currently being broadcast.

  In the method of only displaying the recording date and time and masking the telop part, the user must watch the program while being aware of the recording date and time, which is not a natural viewing method. Therefore, when playing back a recorded program, if the time becomes important, the user can view the program recorded in the past in a natural form that is easy for the user to watch without making the user aware of the recording time. It is demanded.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a video playback device with improved user viewability.

  In order to solve the above-mentioned object, the present invention is characterized in that, when a recorded program whose time is important is reproduced, the program content related to the time is edited into the program content considering the reproduction time and reproduced. And

  ADVANTAGE OF THE INVENTION According to this invention, the video reproduction apparatus which improved the user's viewability can be provided.

FIG. 1 shows an example of components of a video playback apparatus. The video playback device 100 includes a communication unit 101 that communicates with other terminals and devices outside the terminal via an antenna 107, and a reception unit 102 that receives broadcast from a broadcasting station such as a television or radio via an antenna 108. A storage unit 103 that stores data such as sound, images, and video, a display unit 104 that displays image data and video data, an output unit 105 that outputs sound data, and a control unit 106 that controls these. ing.
The communication unit 101 communicates with other information display devices and external devices via the antenna 107. As a result, the user can make calls, the Internet, mail, and the like. In this example, the communication unit is configured. However, a configuration without the communication unit may be used.

  The receiving unit 102 receives a broadcast signal distributed from a broadcasting station such as a radio or a television via the antenna 108. The broadcast signal may include information data regarding the broadcast program and information data regarding the time in addition to the video data and sound data of the broadcast program. The information data related to the broadcast program includes, for example, the name of the program to be broadcast, the name of the performer, the name of the performer currently displayed, the content currently displayed, the caption, the caption supervision, the data broadcast, and the like. In addition, the time-related information data includes, for example, whether the program includes information that is important for time, whether the currently broadcast screen is information that is important for time, program start and end times, re-broadcast If it is a rebroadcast, it includes the contents of the program related to the time, such as the date and time of the first broadcast. The broadcast signal to be received is usually a television broadcast, but it may be a radio broadcast or a data broadcast without video data. In this example, the signal is received via the antenna. However, the signal may be received without the antenna such as cable television broadcasting.

  The storage unit 103 includes, for example, a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. Stores broadcast signals received by the receiving unit 102 described above, records broadcast signals and information data acquired from the communication unit 102 described above, and stores video data, character data, software handled by other video playback devices. To do. Usually, it is configured inside the housing, but may be realized by a removable memory card, a medium such as a CD (Compact Disk) or a DVD (Digital Versatile Disk), a storage device connected from the outside, or the like. The storage unit also stores sound data, image data, character data, and the like used when editing video data.

  The display unit 104 is configured by an LCD (Liquid Crystal Display), an organic EL, or the like, and displays video data included in a broadcast signal received by the receiving unit or a broadcast signal recorded in the recording unit. The output unit 105 outputs sound data included in the broadcast signal received by the receiving unit, sound data included in the broadcast signal recorded in the recording unit, and the like. In the present embodiment, the display unit and the output unit are built in the housing, but may be arranged outside the housing such as a television.

  The control unit 106 is realized by a CPU, operates based on a program stored in the storage unit, and controls each unit.

  In this example, the video playback device is assumed to be a mobile phone. However, any information display device capable of displaying broadcast signals can be used with a television, PHS (Personal Handy-phone System), PDA (Personal Digital Assistant). ), PC (Personal Computer), mobile viewer, etc. Further, as long as a broadcast signal can be displayed, a configuration without a communication unit or a reception unit may be used.

  FIG. 2 is a diagram illustrating an example of a processing procedure of the video reproduction device. When the process is started (S201), the control unit first acquires video data to be reproduced from the receiving unit, the storage unit, the communication unit, or the like (S202). Next, the time when the video data was recorded, that is, the broadcast time (S203), the time when the video data was reproduced, that is, the current time (S204) is acquired. Then, it is determined whether editing is necessary from information such as the acquired time and the content of the video data (S205). If it is determined that editing is necessary, determine how to edit the video data (S206), edit the video data (S207), and output to the display unit or output unit (S208) . If it is determined in step S206 that editing is not necessary, nothing is performed on the video data, and the video data is displayed as it is on the display unit or output unit (S208). Next, it is determined whether there are further broadcast signals and video data to be reproduced (S209). If there are still broadcast signals to be reproduced, the process returns to step S202 to repeat a series of processing procedures. If there is no broadcast signal to be reproduced, the process is terminated (S210).

  In this example, whether or not to edit is determined from the recording time, reproduction time, and program content, and the program content is extracted from the program content in the information data transmitted together with the video data as a broadcast signal in digital broadcasting. However, text data of teletext, voice recognition from video, recognition and extraction of video, extraction from EPG (Electronic Program Guide), etc., information data If it is possible to extract the contents of the program necessary for the judgment, such as using information on whether editing is necessary or whether the program is time-critical, any method can be used. There may be.

  The editing target is all the content to be reproduced, such as an image portion of video data transmitted as a broadcast signal, sound data, character data, subtitles, and data broadcasting. Of course, when editing, it is also possible to apply editing processing to only one part of the broadcast signal, such as editing only captions or caption data. In this embodiment, it is assumed that the location to be edited can be specified by the program content in the information data transmitted together with the video data as a broadcast signal in digital broadcasting. It can be specified by any method as long as the location to be edited can be specified, such as using it, recognizing the voice from the video, recognizing and extracting the video, or extracting from the EPG (Electronic Program Guide). May be.

  Also, the broadcast station may transmit the necessity of editing by time and the specific editing method along with the video data in the broadcast signal to be transmitted, and it is suitable not for the editing method but for the playback time. Alternatively, a program to be replaced may be transmitted. These may be obtained not only from the broadcast signal but also from the Internet or an external device. Also, instead of extracting the contents of the program in real time, the corresponding program was reproduced at the corresponding reproduction time from the table showing the program to be reproduced, the editing method applied, and the reproduction time obtained in advance from a broadcast signal or the Internet. In some cases, a corresponding editing process may be applied. Here, the time is not limited to hours, minutes, seconds and the like, and any time may be used as long as it relates to the time such as the year or date.

  FIG. 3 shows an example of how editing is performed during video playback. When acquiring video data to be played back from the communication unit 101, the receiving unit 102, the storage unit 103, etc., the control unit 106 acquires the time when the video data was recorded and the time when the video data was played back. In this example, the recording time is “January 18, 2005, 7:00 pm”, and the playback time is “January 19, 2005, 1:00 pm”. Then, from the contents of the program of the information data transmitted together with the video data, it is determined whether the program is a program whose time is important or needs to be edited, and similarly from the information data transmitted. Decide how to edit. In this example, since the reproduction program is a weather forecast program from the program content of the information data transmitted together with the video data, it is determined that the time is an important program and editing is necessary.

  Next, from the program content of the information data transmitted together with the video data, there is a content that the caster says “Today's weather forecast ...” in the program, and from the recording time and playback time, the user In order to avoid confusion, it is determined that the voice should be edited as “Tomorrow is” as “Today is”. Then, the edited video data is displayed on the display unit 104 and output to the output unit 105. As a result, even when a user views a past program, the user can naturally view appropriate information without being aware of when the recorded information is recorded. Of course, when the recording time is important, editing may be performed so that the recording time can be understood, such as “What is today's weather forecast as of yesterday?”.

  FIG. 4 shows another example of how editing is performed during video playback. When acquiring video data to be played back from the communication unit 101, the receiving unit 102, the storage unit 103, etc., the control unit 106 acquires the time when the video data was recorded and the time when the video data was played back. In this example, the recording time is “January 19, 2005 Wednesday 7:00 pm” and the playback time is “Monday 24 January 2005 1:00 pm”. Then, from the contents of the program of the information data transmitted together with the video data, it is determined whether the program is a program whose time is important or needs to be edited, and similarly from the information data transmitted. Decide how to edit. In this example, since the reproduced program is a program announcement program based on the program content of the information data transmitted together with the video data, it is determined that the time is an important program and editing is necessary. Next, from the program content of the information data transmitted together with the video data, “This time of next week” is displayed on the screen, so that the user will not be confused from the content, the recording time, and the playback time. "" Wednesday "or" 23rd ", and" This time "is" 7 o'clock "," Night ", etc., and the editing method is determined. Then, the edited video data is displayed on the display unit 104 and output to the output unit 105. As a result, even when a user views a past program, the user can naturally view appropriate information without being aware of when the recorded information is recorded.

  Time related greetings, such as editing “Good morning” to “Good evening”, editing the current time displayed in the corner of the screen in a news program, etc. to the playback time, etc. If it is deemed necessary, any editing may be performed. In addition, when the recorded program is rebroadcast at the stage of recording, the time of the first broadcast may be used as the recording time.

  If the recorded program is meaningless information at the time of reproduction, the next program or scene can be reproduced without reproducing the program or scene. FIG. 5 shows the processing procedure. When the processing is started (S501), the control unit 106 first acquires video data to be reproduced from the receiving unit 102, the storage unit 103, the communication unit 101, or the like (S502). Next, the time when the video data was recorded, that is, the broadcast time (S503), the program, the time when it was played back, that is, the current time (S504) is acquired. Then, it is determined from the information such as the acquired time and the content of the video data whether editing is necessary (S505). If it is determined that editing is necessary, it is determined whether the program is video data that is meaningful and reproduced at that time (S506). If it is determined that it should be played, decide how to edit the video data (S507), edit the video data (S508), and output to the display unit 104 and output unit 105. (S509). If it is determined in step S505 that editing is not necessary, nothing is performed on the video data, and the video data is displayed on the display unit 104 or the output unit 105 (S509). In step S506, when it is determined that the video is not to be reproduced, or after being displayed on the display unit 104 or the output unit 105 (S509), it is determined whether there is a further broadcast signal to be reproduced (S510). If still exists, the process returns to step S502, and a series of processing procedures is repeated. If there is no broadcast signal to be reproduced, the process is terminated (S511).

  For example, if the weather forecast is the contents of the date recorded on “January 20, 2005” and the reproduced is “February 20, 2005”, the weather forecast for January 20 is set to February Since the user does not see it on the 20th, only the weather forecast portion is skipped and reproduced. Alternatively, if the program that was announced in the program announcement has already been broadcast and cannot be viewed even if the user wants to see the announcement, the program announcement can be replayed. If it is judged that it is not possible to skip the program announcement and play it, or if the program that was making the announcement is canceled and it is meaningless to play the announcement, the announcement will be skipped and played. . Further, whether or not the information should be reproduced may be determined based on whether or not the program is recorded on the recording unit or the like. For example, if a program to be played is a program that announces a program to be broadcast, even if the announced program has already been broadcast, if it has been recorded in the storage unit, skip it. Without playing.

  Further, a program to be reproduced may be edited using a program recorded in a recording unit or the like. For example, if the program to be played is weather forecast or news, the recording date / time is old, and there is no meaning for the user even if it is played back, but there is a weather forecast or news recorded at the time valid for playback in the recording unit For example, it can be replaced and played.

  Further, it may indicate that a program that has been announced, a new weather forecast, or the like has been recorded, and that the program may be reproducible by a user operation.

  In this example, the video playback device alone has a configuration with all functions, but other external devices have a control unit, a recording unit, etc., and the video playback device communicates with the external device, etc. A series of functions may be realized by the apparatus. The external device may be configured to perform one function of the control unit, for example, determination of necessity of editing or determination of an editing method.

  Also, at that time, the user can select, switch or automatically switch whether all processing is performed by the video playback apparatus alone or by using an external apparatus. When the remaining battery level is low, a setting may be made so that the processing operation is not automatically performed.

  As described above, according to the present embodiment, the user may be confused by a time lag when playing a video that is important for the playback time such as a program trailer, CM, weather forecast, and news recorded in the past. Therefore, the user can enjoy the program naturally without being aware of when the video is recorded or broadcast. As a result, the user can provide a user-friendly video playback device that can be enjoyed naturally.
