Description

  The present invention relates to a display method and a display device, and more particularly to a display method and a display device for applying an effect to a screen displayed to a user at a predetermined timing.

  In recent years, thin-screen image display devices (hereinafter simply referred to as “thin TVs”) such as liquid crystal TVs and PDP (plasma display panel) TVs have become larger, and TVs with a size of 50 inches can be purchased by general consumers. It has become a price. With such a large television, you can enjoy various contents in an environment full of realism.

  For example, while at home, you can enjoy content as if you were in a movie theater, or enjoy sports broadcasting as if you were in a stadium.

  By the way, the competition among manufacturers in the above-mentioned flat-screen television market is extremely fierce, and each company implements various technologies to achieve further improvement in video quality and to differentiate itself from other companies. Under such circumstances, not only the basic performance such as the display quality is set as a selection criterion of the user, but other additional functions are becoming important.

Further, as one of the technologies assumed as such an additional function, there is an effect application (see Patent Document 1). With the technique disclosed in Patent Document 1, various fade patterns can be given to video shot by a video camera.
Japanese Patent Publication No.8-8660

  In the technique disclosed in Patent Document 1, the user selects a desired fade pattern and gives an effect to the video shot by the user. However, although it is a very effective technique when performing video editing, there has been a problem that it cannot be used when simply viewing content such as television broadcasting or DVD (Digital Versatile Disc) video. In particular, there has been a demand for a technique for appropriately determining the timing for applying a display effect without interruption while content such as a television is flowing. The program start time can be specified by EPG (Electronic Program Guide), but in television broadcasting, commercials may be inserted at the beginning, and depending on the content, there will be a gap between the start time of the main part There was a thing. Further, in rental DVDs and the like, commercials are sometimes inserted prior to the main part, and the same problem has occurred.

  This invention is made | formed in view of such a condition, The objective is to provide the technique which provides the display effect suitable for the content with the appropriate timing with respect to the content displayed to a user.

The method according to the present invention relates to a display method. This display method includes a step of determining the presence or absence of start pattern data output prior to the main content, and a predetermined display in accordance with the appearance of the start pattern data when it is determined that there is the start pattern data. And displaying an effect.
Further, the content may be added to the content while the predetermined display effect and the start pattern data are flowing.
Further, the display pattern may be provided when the start pattern data and the reference data stored in advance are compared, and the start pattern data matches the reference data.
The device according to the present invention relates to a display device. The display device includes a pattern data holding unit that holds, as reference data, start pattern data that is output prior to the start of the main part of the content, and the reference data when the content data is input, A data determination unit that determines whether or not reference data is included in the data of the content, and if it is determined that the reference data is included in the start pattern data, a display effect is applied to the start screen of the content And an effect applying unit.

  ADVANTAGE OF THE INVENTION According to this invention, a display effect can be provided to the content which a user views at a predetermined timing.

  Next, the best mode for carrying out the present invention (hereinafter simply referred to as “embodiment”) will be specifically described with reference to the drawings.

  In this embodiment, first, the start time of content is specified, and when the start time is reached, a display effect with the curtain closed is applied to the content. Subsequently, if the content is a television broadcast series program or a movie DVD video, a specific video or music may flow at the beginning. For example, in a series of programs such as “ABCD road show” which is a movie program, a specific video or specific music common to the series may be played at the beginning of the program. Also, in movie DVD video, video and music unique to each movie company are inserted at the beginning of the content. Hereinafter, the specific video and the specific music at the beginning of the content are referred to as “opening video” and “opening music”, respectively. At the start of the opening video or opening music, a display effect that opens the curtain is added to the content.

  In addition, at the end of the content, an image called an end roll (end credit) in which performers, producers, and the like are described may be displayed. When such an end roll is displayed or ending music is played, it is determined that the main part of the content is finished, and a display effect for closing the curtain is given to the content. Hereinafter, the end roll is referred to as an ending video. Hereinafter, the opening video and the opening music are referred to as “start pattern data”, and the ending video and the ending music are referred to as “end pattern data”. Furthermore, the start pattern data and the end pattern data are collectively referred to as identification data (pattern data).

  FIG. 1 is a functional block diagram showing the configuration of the television 10 according to the present embodiment. Note that the present embodiment is not limited to a television but can be applied to a device that displays video such as a video device.

  The television 10 includes a tuner 11, a main control unit 15, a display control unit 20, an external input unit 16, an operation acquisition unit 17, and a display unit 18. The television 10 further includes an effect applying unit 30. The main control unit 15 controls the operation of each component of the television 10 and performs time management using a timer function. The main control unit 15, the display control unit 20, and the effect applying unit 30 are stored in, for example, an LSI (Large Scale Integrated Circuit) such as a CPU (Central Processing Unit), a memory, and the memory and execute each function. It is realized by the program to do.

  The tuner 11 is connected to the antenna 19 and receives and decodes terrestrial digital broadcasting. The tuner 11 includes a receiving unit 12 and a decoding processing unit 13. The receiving unit 12 selects a desired channel, performs demodulation processing and error correction processing, and extracts a TS (transport stream) transmitted from the broadcasting station. In addition, the decoding processing unit 13 separates the multiplexed TS for each purpose, decodes the video data and the audio data, and outputs, for example, data broadcast data other than the data to the main control unit 15. The decoded video data is output to the display control unit 20.

  The external input unit 16 acquires desired content from an external video device 42 such as a video device or a DVD player, and outputs the acquired content data to the display control unit 20. The operation acquisition unit 17 receives a user's direct operation through a predetermined interface (not shown) such as a switch provided in the television 10 or an indirect operation by the remote controller 43.

  The display control unit 20 includes a selector 21, a video construction unit 22, and an effect control unit 23. The selector 21 selects the tuner 11 or the external input unit 16 and connects it to the display unit 18. The video construction unit 22 should finally display on the display unit 18 by, for example, composing a screen reflecting the contents of the data broadcast as necessary, or assigning the number and time of the selected channel. Build a video. Further, the effect control unit 23 provides the display effect determined by the effect applying unit 30 described below to the content.

  In addition, the effect applying unit 30 includes a content determination unit 31, a content specifying unit 32, a pattern selection unit 33, and a pattern acquisition unit 34. The effect applying unit 30 further includes an effect storage unit 35, a specifying data storage unit 36, a genre specifying unit 37, and a specifying data acquisition unit 38.

  The content determination unit 31 determines whether or not to apply the display effect to the content at the timing when the channel is changed, the connection is switched to the external video device 42, or the start or end time of the content approaches. The effect control unit 23 is notified of the display effect to be performed.

  As the judgment, if it is a content of terrestrial digital broadcasting, information sequence information SI and EPG information included in the TS is acquired from the tuner 11 via the main control unit 15, and the program start time and end time are referred to. The content determination unit 31 determines. When the content of the external video device 42 is being played back, the content determination unit 31 acquires and determines the content length (time) and the progress degree of the chapter from the external video device 42. Alternatively, the start or end of content playback may be determined based on the timing at which the audio signal changes from stereo to 5.1ch, for example.

  In addition, the content specifying unit 32 specifies the program title of the content with reference to the EPG. Further, in the case of content being played back by the external video device 42, that is, when the selector 21 selects the external input unit 16, this is acquired. The content specifying unit 32 specifies the genre of the content. Specifically, in the case of digital terrestrial broadcast content, the content genre is specified as, for example, “movie”, “sports”, “drama” or the like based on the program arrangement information SI and EPG included in the TS. . In addition, the content specifying unit 32 compares whether or not the specifying data described in the list table held in the specifying data storage unit 36 to be described later matches the content being reproduced, Determine whether the main story has started or ended. The comparison of whether or not they match can be realized by a known image matching method or voice matching method. For example, a pixel having the same brightness and hue is determined. If the number of pixels determined to match within one frame is 80% or more of the whole, it is determined that the specifying data matches the content being reproduced. The

  Further, the content specifying unit 32 can manage the progress of pattern data. Specifically, the content specifying unit 32 compares the opening video and music, and further the ending video and music with the specifying data, and specifies the opening video and music, and further the end timing of the ending video and music. Based on the identified timing, the effect control unit 23 controls the display effect applying speed. For example, if the display effect is assumed to open the curtain of a movie theater, the content specifying unit 32 specifies the timing when the opening video or music ends, and the effect control unit 23 opens the curtain at that timing. Control the speed of applying the display effect. In addition, if the main part of the content starts before the display effect ends, the display effect can be applied so that the opening can be quickly opened by speeding up or skipping the subsequent opening display. Is controlled. The determination of the start or end of the main part can be realized by using a general scene change determination method in addition to the pattern data collation, for example.

  The specifying data storage unit 36 has a predetermined file format by user operation so that the specifying data, that is, the opening video and opening music flowing at the beginning of the content, and the ending video and ending music flowing in the ending can be used for matching processing. Memorize and accumulate with. For example, the specifying data may be a moving image or a still image as long as it is a video, or may be data for a plurality of frames in the case of a still image. Any format that is preferable for the matching process may be used. For example, if a predetermined feature amount is correlated between images, the feature amount may be converted and stored. Further, a table (hereinafter referred to as “list table”) in which a list of what kind of specification data is held is written is held. Further, in music matching, it is determined that the content and the data for identification match depending on whether or not the same waveform appears. When the display effect application speed is controlled, the specifying data is stored in association with the display time. In particular, when the specifying data does not record the opening video or the like with the full length, the time information indicating the timing portion of the specifying data is also stored. By referring to this time information, the content specifying unit 32 can manage the progress of the pattern data.

  FIG. 2 shows an example of a list table held in the specifying data storage unit 36. FIG. 2A particularly shows a list table corresponding to television broadcasting, that is, a list table corresponding to content acquired by the tuner 11. For each TV program (content title), the genre, the opening video and music reference file names, the ending video and music file names, and the effect code associated with the content genre are written. In addition, in the item “address”, the head portion of the address in the storage area of the specifying data storage unit 36 is written as an area in which each of the files is stored. Using the address as a key, the content specifying unit 32 reads a necessary file into the work area and performs matching processing in the work area.

  For example, for the content title “ABCD roadshow” described at the top of the list table, the genre is “movie”, the opening video file name is “ABCD — 11.xxx”, and the address “00000” is stored. The beginning of the area being The effect code is “01” indicating that the genre is “movie”. Note that “-” is written in the ending music item column, indicating that the ending music file of the content title “ABCD roadshow” is not stored in the specifying data storage unit 36.

  FIG. 2B is a list table corresponding to the content acquired from the external video device 42 in particular. For example, when the same scene as the video of the file “WXYZ — 21.xxx” appears in the content reproduced by the external video device 42, it is determined that the work (content) of the movie company “WXYZ movie” has started.

  The specifying data acquisition unit 38 acquires the above-described specifying data from the external video device 42, the external storage device 44, or the tuner 11.

  The pattern selection unit 33 determines a display effect corresponding to the genre of the content specified by the content specifying unit 32 with reference to the effect code in the list table. A plurality of display effects are recorded in the effect storage unit 35 in association with the effect code. As a display effect, for example, if the content genre is a movie, that is, if the effect code is “01”, an image that reminds the opening and closing of an actual movie theater is the display effect. In addition, if the genre of the content is “soccer”, videos such as a ballpark and a soccer ball may be faded in and out, wiped in, and wiped out. The correspondence between the display effect pattern and the genre may be specified by the user or may be set in advance as an initial pattern. The display effect pattern may be different at the start and end timing of the content. Furthermore, when the genre cannot be specified, a general display effect may be applied. A display effect may be recorded in association with the content (program). In that case, a display effect associated with the program may be given in preference to the genre.

  The pattern acquisition unit 34 acquires a display effect pattern from an external storage device 44 such as a memory card, and stores it in the effect storage unit 35 in association with the program title or genre. Therefore, the viewer can give a favorite pattern to the content in addition to the display effect pattern included in the television 10 in advance.

  A process of applying a display effect to the content at the start or end timing with the above configuration will be described.

  First, the case where a tuner 11 views a digital terrestrial broadcast program as content will be described with reference to the flowchart of FIG. The process according to this flowchart is executed when a mode for applying a display effect to content (also referred to as “effect applying mode”) is selected by the user.

  In a channel selected by the tuner 11, when a predetermined time before the start time of the next content, for example, 1 minute before, the content determination unit 31 acquires information on the next content from the EPG (S 10). Information to be acquired includes the title and genre of content, the start time and the end time.

  The content determination unit 31 determines whether or not the next program is a display effect application target (S12). The determination as to whether or not the display effect is to be given is first made based on whether or not the title of the content is included in the list table held in the specifying data storage unit 36 shown in FIG. If it is not included, it is further determined by whether or not the genre of the program is “movie”. Note that the genre of the target program is not limited to one, and may be plural, or may be designated by the user.

  When the next content is a display effect application target (Y in S12), the content determination unit 31 determines whether or not the title of the content is included in the above list table and further includes an opening video. Judgment is made (S14). When the opening video is included in the list table (Y in S14), the application of the display effect is waited until the start time of the content (N in S16).

  When the start time of the content is reached (Y in S16), as shown in FIG. 4A, the effect control unit 23 gives the display effect with the curtain closed to the content (S18).

  Then, the content specifying unit 32 compares the content video with the opening video held in the specifying data storage unit 36 (S20), and determines whether or not the main part of the content has started (S22). When it is determined that the same video as the opening video appears in the content video and the main part has started (Y in S22), as shown in FIG. 4B, the effect control unit 23 starts from the state where the curtain is closed. A display effect is applied to the content so as to gradually open (S24). When the curtain is completely opened, the effect control unit 23 assigns the curtain as a front effect in a state opened on both sides of the content as shown in FIG. 4C (S26).

Note that the determination as to whether or not the same video as the opening video appears in the displayed content need not be completely the same. For example, the opening video may not completely match because the initial video of the displayed content includes the subtitle of the content. Therefore, when it is estimated that the video excluding the text is the same, it may be determined that the same video as the opening video appears in the content video. The same applies to the ending video described later. Furthermore, the comparison target may be a part rather than the whole, and it may be compared whether or not a predetermined video or text is included.

  Returning to the description of the processing in S22, when the main part has not yet started (N in S22), the content determination unit 31 determines whether or not a predetermined time, for example, one minute has elapsed since the display of the content was started. (S28). When the predetermined time has elapsed (Y in S28), the effect control unit 23 displays a state in which the curtain is opened (S26). By performing such processing, content display can be forcibly started when the start of the main part cannot be determined, when the opening video is changed, or skipped. If the predetermined time has not elapsed (N in S28), the process returns to S20.

  Returning to the description of the processing in S14, when it is determined that the opening video is not included in the list table (N in S14), the display effect is not given until a predetermined time before the start time of the content, for example, 30 seconds before ( When the predetermined time before the start time comes (N in S30) (Y in S30), the effect control unit 23 applies the display effect with the curtain closed to the content (S32).

  In this state, it waits until the start time of the content (N in S34), and when the start time is reached (Y in S34), the effect control unit 23 gives the content a display effect that gradually opens the curtain (S24), When it is fully opened, it is displayed with the curtain open on both sides of the content (S26). At this time, the content determination unit 31 estimates the start timing of the main part by specifying the degree of progress of the opening video, and the effect control unit 23 adjusts the opening speed of the curtain in response to the estimated timing. Good.

  By performing the above processing, it is possible to give a display effect to the content at the timing when the main part of the content starts. Even if the start of the main part of the content cannot be specified, a display effect can be applied to the entire content at the timing when the display is started. Accordingly, for example, when the display unit 18 is a large display panel and the display effect is a curtain, it is possible to create an atmosphere of a scene where a movie starts in a movie theater while at home.

  Next, processing for applying a display effect when content ends will be described with reference to the flowchart of FIG.

  First, the content determination unit 31 determines whether or not the current content is an effect application target (S50). This determination may use the determination result as to whether or not the content is to be applied when the content starts in the flowchart shown in FIG. If the content is not the subject of the effect (N in S50), this process ends.

  The content determination unit 31 determines whether or not the ending video of the current content is included in the list table when a predetermined time before the end time of the content, for example, 5 minutes before the end time (S52). This determination may be made at the time of determining whether or not it is included in the list table in the flowchart shown in FIG. 3, and in this case, a predetermined flag indicating the determination result may be set.

  When the ending video is included in the list table (Y in S52), the content specifying unit 32 compares the ending video with the content video, checks whether the ending video appears in the content (S54), It is determined whether or not the main part is finished (S56).

  When it is determined that the main part of the content is finished, that is, when an ending video appears as shown in FIG. 6 (a), the effect control unit 23 gradually starts the content as shown in FIG. 6 (b). A display effect is applied to the screen, and the curtain is closed as shown in FIG. 6C (S58). At this time, the content determination unit 31 estimates the end timing of the ending video by specifying the progress degree of the ending video, and the effect control unit 23 adjusts the speed at which the curtain closes in response to the specification of the timing. Good.

  In the process of S56, when it is determined that the main part is not yet finished, that is, when the ending video of the content does not appear (N in S56), the content determination unit 31 determines whether or not the end time has come (S60). Here, the end time may be a timing at which the user can substantially recognize that the content has ended, may be an EPG end time, or may be a predetermined time before the end time, for example, 10 seconds before. May be. If it is not the end time (N in S60), the process returns to the determination of whether or not the ending video has appeared (S54).

  When it is determined that the end time has been reached or elapsed (Y in S60), the effect control unit 23 gives the content a display effect that gradually closes the curtain (S58). By performing such processing, it is possible to notify the user that the program has ended when the end of the main part cannot be determined, or when the ending video has been changed or skipped.

  Returning to the description of the processing in S52, when the ending video is not included in the list table (N in S52), the state where the display effect is displayed on both sides of the content continues until the end time (N in S62). When the content end time is reached (Y in S62), the effect control unit 23 applies a display effect for gradually closing the curtain to the content (S58). Thus, the process according to the flow shown in FIG. 5 is completed.

  Next, a case where a DVD video whose content is a movie is acquired from the external video device 42 and played back will be described with reference to FIG. Here again, it is assumed that the effect applying mode is selected in the television 10.

  First, when content is sent from the external video device 42, the effect control unit 23 applies an effect with the curtain closed to the content (S70). Subsequently, the content specifying unit 32 selects the opening video of the movie company from the opening video stored in the specifying data storage unit 36 (S72). Further, the content specifying unit 32 compares the content with the opening video, confirms that the selected opening video appears (S74), and determines whether the main part of the content has started (S76). A plurality of opening videos may be selected. If the main part has not started (N in S76), the effect control unit 23 continues to check whether the opening video appears (S74).

  When it is determined that the main part of the content has been started (S76), the effect control unit 23 applies a display effect that gradually opens the curtain to the content (S78).

  Regarding the end of the content, it is determined whether or not the display of the end roll is started. If it is determined that the display is started, a display effect for closing the curtain is applied to the content. Thus, when viewing a movie on a DVD video, the start timing of the main part of the content can be specified by confirming that an opening video unique to each movie company appears in the content. In addition, by confirming the end roll, the end timing of the main part of the content can be specified.

As described above, according to the present embodiment, a display effect corresponding to the genre can be given to content at an appropriate timing. As a result, it is possible to provide a means for the user to enjoy the content more. In particular, thin display devices such as liquid crystal televisions that are larger than 50 inches are purchased by general consumers. Therefore, when viewing the content of a genre such as a movie, if the curtain is displayed at the start or end timing on the large screen as described above, the viewer feels as if they are in a movie theater while at home. Can be provided. In particular, even if there is a time lag between the start and end times of the content and the start and end times of the main content due to the insertion of a commercial, etc., the start time of the main content or Add a display effect to the end time

  The present invention has been described based on the embodiments. This embodiment is an exemplification, and it will be understood by those skilled in the art that various modifications can be made to the combination of each component and each processing process, and such modifications are also within the scope of the present invention. .

  The present invention can be widely used for display devices such as televisions.
