Description

  The present invention relates to a television receiver and a video recording / playback device, and in particular, a television receiver that allows a viewer to easily determine whether to re-view by storing the output state of video and audio signals of a viewed program. The present invention relates to an apparatus, a video recording / playback apparatus, and a video recording / playback system including the same.

  2. Description of the Related Art In recent years, techniques for receiving digital TV broadcasts in mobile broadcast digital broadcast receivers such as mobile phones and in-vehicle TV receivers have been developed. Accordingly, since the television receiver can be used both indoors and outdoors, it is expected that viewing opportunities and places will be expanded. In Japan, digital terrestrial broadcasting divides the frequency band of one channel (6 MHz) into 13 and broadcasts for mobile in one frequency band (one segment) of the center frequency of one channel that is most easily received. Further, high-definition broadcasting or the like is performed in the other divided 12 (12 segment) frequency bands.

  The television receiver may not be able to receive the broadcast correctly depending on the state of the broadcast radio wave. In particular, a portable television receiver may not be able to continuously watch television broadcasts due to changes in the reception state of broadcast waves due to changes in the surrounding environment and the circumstances of the viewer. In such a case, there is a desire to review the program viewed on the portable television receiver later.

  Therefore, in the conventional portable terminal device, when the broadcast radio wave is interrupted, the time and channel are stored as a bookmark, and it is sent to the TV reception / recording / playback device, and the viewer has not viewed it based on the bookmark information. There is one that reproduces a part (see, for example, Patent Document 1).

Also, some conventional portable information terminal devices store a viewing history of a received and displayed video signal, and a recording / playback device performs playback with reference to the viewing history (see, for example, Patent Document 2). .

  As shown in FIG. 1, in the portable television receiver 101, the channel selection unit 2 can change the frequency band of the radio wave that is selected and received. The channel selection unit 2 normally receives signals with a wide band frequency, and switches the reception to a narrow band frequency that is easy to receive when the radio wave condition deteriorates. Since the amount of information per unit time is larger when receiving with a wideband frequency than when receiving with a narrowband frequency, high-quality video and audio can be output to the display unit 6 and the speaker 7. For example, when receiving domestic terrestrial digital broadcasting, it is usually received in 12 segments (when the radio wave condition is good) and switched to reception of one segment when the radio wave condition deteriorates. If the radio wave condition becomes considerably worse, even one segment cannot be received. Switching of the frequency band of the channel selection unit 2 may be performed automatically by detecting the reception state, or may be performed manually by the viewer. Note that the frequency band may be divided in any manner depending on the broadcasting system. In this embodiment, there are three reception states: (1) reception of 12 segments, (2) reception of 1 segment, and (3) inability to receive. At the time of reception, the control unit 4 of the portable television receiving apparatus 101 determines which of the three reception states is received, and stores reception state data representing the determined reception state in the storage unit 5.

  FIG. 2 is a format example of data that is stored in the storage unit 5 and that represents the reception state of the television broadcast radio wave, the video signal output display state of the television reception unit, and the audio signal output state. In FIG. 2, an example of data in the storage unit 5 is illustrated in a table format, but an actual data representation format and storage format are not limited to this example. As shown in FIG. 2, the storage unit 5 stores the reception state, channel, video signal output display state, audio signal output state, start date / time, end date / time, and program information data being viewed by the control unit 4. Remembered. The control unit 4 updates the storage unit 5 every time there is a change in at least one of the reception state, channel, video signal output display state, audio signal output state, and program information being viewed of the portable television receiver 101. Add and record new records.

  As the reception status data, the channel selection unit 2 is set to “12” when received by 12 segments, “1” when received by 1 segment, and “x” when it cannot be received. As the channel data, the channel number selected by the channel selection unit 2 is set.

  As the video signal output display status data, “full” is displayed when the television broadcast video is displayed on the full screen on the display unit 6, “half” is displayed when the half screen of the display unit 6 is displayed, and the television broadcast is displayed. If there is no “x”, it is set. When the setting value is “half”, the video signal output of the television broadcast is displayed on the half screen of the display unit 6 and the Web menu or the data broadcast display is performed on the other half. As the audio signal output state data, “◯” is set when a television broadcast sound is output to the speaker 7, and “X” is set when it is not output.

  In the start date and time data, the date and time when the reception state represented by the record occurs is set. As the end date and time, the date and time when the reception state represented by the record ends is set. As the program information, program information (program name, broadcasting time, broadcasting station name, etc.) acquired from data broadcasting or the Internet is set. When program information cannot be acquired from data broadcasting or the Internet, program information (program name, broadcast time, broadcast station name, etc.) may not be stored.

  Note that the broadcast wave reception state may change in a short time. In addition, when a viewer selects a channel, the channel may be finally determined after watching a program of a plurality of channels for a short time. Therefore, as described above, in principle, the control unit 4 sets at least one of the reception state, channel, video signal output display state, audio signal output state, and program information being viewed of the portable television receiver 101. Each time there is a change, a new record is added and stored in the storage unit 5, but it is better to perform a process of ignoring the change for a short time (for example, within one minute). That is, even if a change in the reception state, the video signal output display state, and the audio signal output state occurs, if the time when the change occurs is less than one minute from the previous change, the set values for the time before and after the change are bad. Is set as the setting value. However, if the change in the set value is still less than 1 minute, the process is repeated until 1 minute or more. If the change in the channel setting value is less than 1 minute, unviewed is set as the setting value.

  In the example of FIG. 2, the following situations are stored. 2006/4/20 TV broadcast reception started at 18:00:53, and until 2006/4/20 18:03:45, 32 channels of "Professional Baseball-A Baseball Team Team B x Team C" Video and audio are output to the display unit 6 and the speaker 7. The reception state is 12 segments, the television broadcast video is displayed on the display unit 6 on the full screen, and the television broadcast audio is output to the speaker 7. Since 2006/4/20 18:03:45, TV was being watched. However, the mobile phone transmitting / receiving unit 10 was called and the speaker 7 was replaced with the voice of the telephone. The same program is displayed in the same reception state, but the audio signal output setting is “X”. From 2006/4/20 18:05:20, the telephone call ends and TV broadcast audio is output to the speaker 7, but the TV broadcast video is displayed on the display unit 6 in a half-screen display, and the remaining half-screen displays data. Broadcast data and operation menu are displayed.

  From 2006/4/20 18:10:32, the reception state deteriorated, and the channel selection unit 2 switched to one segment and continued reception. From 2006/4/20 18:29:30, the reception state is further deteriorated, and even one segment cannot be received. On 2006/4/20 18:29:45, reception of television broadcasts is stopped. Reception of TV broadcasts was resumed from 2006/4/20 19:34:02, received in 12 segments, and video is displayed on the display unit 6 on the entire screen. On 2006/4/20 19:58:00, the channel was changed to "35". At this time, since it cannot be received in 12 segments, it is received in 1 segment, and a television broadcast video is displayed on the display unit 6 in a half-screen display. At 2006/4/20 20:00, the program being watched changed.

  In the above example, three types (12, 1, x) are exemplified as the reception state data. However, when other reception states occur depending on the broadcasting system, other setting values may be used. Further, three examples of “full”, “half”, and “×” are illustrated as examples of the video signal output display data. However, the video display on the display unit 6 may include a main screen and a sub-screen display. Therefore, the set value may be changed according to the function of the television receiver. The data stored in the storage unit 5 is not limited to numerical values and characters that can be easily identified by humans as described above, and may be binary notation.

  The control unit 4 also has a function of collecting the reception state data in the storage unit 5, the video signal output display state data, and the audio signal output state data for each program and displaying them on the display unit 6. FIG. 3 shows an example in which reception status data, video signal output display status data, and audio signal output status data are displayed together for each program. The control unit 4 creates a display format based on the program name and broadcast time of the program information stored in the storage unit 5 and displays the display format on the display unit 6. In the example of FIG. 3, the information is only displayed in text, but a still image of the image displayed when the reception state, the video signal output display state, or the audio signal output state changes is created. It is also preferable to display. This is because it becomes easier for the viewer to determine re-viewing.

  According to such a configuration, the reception / output state of the video signal and the audio signal of the television receiver 19 when the program is viewed on the portable television receiver 101, and the output of the video signal and the audio signal to the display unit 6 and the speaker 7. Time, etc. can be displayed in an easy-to-understand manner. As a result, the viewer can check in what reception / output state the portion of the watched program can be viewed and determine whether or not to re-view the same program. Can do.

  If you want to watch it again, there are a method of watching the rebroadcast, a method of purchasing / renting if it is converted to a video, and a method of obtaining from a video server on the Internet.

  Although the form of the television receiver is not specified, the best video is not always seen in portable television and car television because the reception state changes. In addition, since current mobile TVs have small screens, it is difficult to understand whether the image quality is good or bad. For example, in the case of a projection-type mobile TV, the screen becomes large, so the quality of the image is a concern. In addition, a stationary television displays a multi-screen display, a menu for data broadcasting, and the like, so that it is not always possible to watch on a full screen, and there is a desire for re-viewing.

  The external storage unit 12 copies the data in the storage unit 5, that is, data relating to the reception state, the video signal output display state, and the audio signal output state. The external storage unit 12 can be attached to and detached from the television receiver 19 of the portable television receiver 101. Thus, by using the external storage unit 12 as the external storage unit 14 of the video recording / playback apparatus 102, the reception state, the video signal output display state, and the audio signal when the portable television receiver 101 receives a broadcast. Data relating to the output state can be passed to the video recording / playback apparatus 102.

  As a method of transferring data in the storage unit 5 to the video recording / playback apparatus 102, in addition to a method of using the external storage unit 12, a method of sending by communication between the communication units 13 and 16, There is a method of exchanging information with the communication unit 16 by electronic mail.

  The detachable external storage unit 12, communication unit 13, and mobile phone transmission / reception unit 10 can also receive the TV reception unit video signal and audio signal when watching a program, even with other TV receivers having this function. The output status information can be exchanged. As a result, the information can be unified regardless of which television receiver having this function is viewed.

  As a method of viewing the same program viewed on the portable television receiving device 101 on the video recording / reproducing device 102, a method of recording and recording in advance on the video recording / reproducing device 102, or a program that has been converted into a video is a video. There are ways to purchase or rent. There is also a method of sending a reservation recording command to the video recording / playback apparatus 102 by e-mail by the mobile phone transmitting / receiving unit 10 of the mobile TV receiving apparatus 101.

  The e-mail sent from the mobile phone transmission / reception unit 10 is received by the communication unit of the video recording / playback apparatus 102 via the telephone network / network 104 and the network communication device 105, and the control unit 15 receives the recording reservation command of the e-mail. Set recording reservation with. When the reservation date / time is reached, the control unit 15 sends a recording command to the recording / reproducing unit 18 to record the designated program.

  The recorded program is recorded in the recording / reproducing unit 18 together with the video signal and the audio signal, with the program name / recording start time / recording end time as recording information. Note that the recording information is not limited to a combination of a program name, a recording start time, and a recording end time, and is an arbitrary combination including at least one of program information, recording time information, and channel information. The recording information may be a combination of recording time information and channel information, for example. In this case, the program information may or may not be included in the recording information. Further, the recording information may be only program information. In addition, in the case where the same broadcasting station series becomes a different channel in the recorded location and the viewed location, or when the same program is rebroadcast, the program information is added to the recording time information and the channel information. is necessary.

  Based on the information of the reception state at the time of viewing the program in the portable television receiver 101 and the output state of the video signal and audio signal of the television receiver in the external storage unit 14, program information corresponding to these information is recorded and reproduced. Search from the unit 18. As the search key, program / channel / start date / time / end date / time can be used. However, when the program information is not stored in the external storage unit 14, the channel / start date / time / end date / time of the external storage unit 14 is compared with the channel / start date / time / end date / time information of the recorded program. Search for the same program. When purchasing or renting a video of a video program, or when replaying or recording from another broadcast station (channel) is played on the video recording / playback device 102, the channel / start date / end date / time is searched. Because it cannot be targeted, search only with program information. If there is a matching program, the program viewed on the portable television receiver 101 is recorded in the video recording / playback apparatus 102.

  For example, “Professional Baseball-A Baseball Team Team B × Team C” from 2006/4/20 18:00:00 to 2006/4/20 19:59:30 on the video recording / playback apparatus 102 is recorded. The case where this is done will be described.

  When the program is played back, first, if the program information is searched and matched, the channel is further searched. The start date / time and end date / time are included in the time of the program recorded in the video recording / playback apparatus 102.

  FIG. 4 shows an example in which the data of the reception state when viewing the program in the portable television receiver 101 and the output state of the video signal and audio signal of the television receiver are displayed for each program of the video recording / playback apparatus. When the program “Professional Baseball to A Baseball Team B × Team C” recorded in the recording / playback unit 18 is played back, the program information in the data stored in the external storage unit 14 and the recording / playback unit 18 The program / channel / start date / time / end date / time recorded in is compared and searched. As a search result, the control unit 15 stores the reception status at the time of viewing the program in the portable television receiver 101 and the video signal of the television reception unit stored in the external storage unit 14 with respect to the total recording time of the program. The audio signal output state data is tabulated as a reception / output state and displayed on the display device 103 via the television receiver 17. Also, if there is no information on the reception state or output state, it is not viewed.

  Further, the control unit 15 creates and displays a still image of the change point of the reception / output state. At this time, the video signal of the change point of the reception / output state and the pointer of the recording location of the audio signal recording / reproducing unit 18 are stored in the storage unit 5. Since there is a high possibility that this change point is designated as a reproduction location, the processing when designated is fast. If it has not been viewed or cannot be received, a still image is created from the video signal at the time received by the portable television receiver 101 immediately before and after that. If unviewed or unreceivable continues, the portable television receiver 101 cannot receive a television broadcast during that time, so a still image is not created. The viewer inputs only the part to be reproduced from the operation unit 20 from the display content. The control unit 16 receives this input, and displays the time zone of the portion to be played and the total playback time (see FIG. 4). The viewer can input the confirmation of this setting from the operation unit 20 and can play back and view only the portion to be played back.

  When playing back a recorded program, it may be considered unnecessary to re-view the part that has already been viewed, but it was viewed without receiving by one segment, half-screen (half) or TV broadcast sound. Depending on the viewer's preference, there may be a desire to reproduce and review the portion. For this reason, in this embodiment, the display of the still image as shown in FIG. 4 or the display of the time zone of the recorded program can be used as a material for determining whether to reproduce.

  For example, in the example shown in FIG. 4, from 2006/4/20 18:00 to 2006/4/20 18:00:53, it was not viewed on the mobile TV receiver 101, but still images ( Since it can be seen from the circled numbers 1) shown in FIG. 4 that the commercial at the beginning of the program is included in this time zone, the viewer has determined that the broadcast recording of this time zone does not require playback.

  In addition, in advance, conditions are set for the data of the reception state at the time of watching the program in the portable television receiver 101 and the output state of the video signal and the audio signal of the television receiver, and the data corresponding to the condition is handled. The program recording may be automatically played back. For example, if the reception state is “12”, the video signal output display state is “full”, and the audio signal output state is other than “o”, the recording of the program is set to be reproduced. 4/20 18:00:00 to 2006/4/20 18:00:53 Recording of viewing programs, 2006/4/20 18:03:45 to 2006/4/20 19:34:02 It is also possible to automatically play back recorded programs. In the case of automatic reproduction, each successive reproduction portion may be enlarged and reproduced for a predetermined short time before and after the setting in advance. As a result, a portion of the viewed program that has been viewed is also reproduced, which makes it easier for the viewer to understand the connection before and after the program.

  For the playback location by the operation unit 20, the playback start time and the playback end time are input using the numeric keys of the operation unit 20, and the “OK” button (see FIG. 4) displayed on the display device 103 is selected. It can be specified by performing a confirmation operation.

  One playback location is determined at the point of pressing the determination of the playback end time. When there are a plurality of playback locations, the operation of inputting the playback start time and playback end time and confirming with the enter button is repeated a plurality of times. In the total playback time, the playback time of the program is displayed. Here, when the “play” button (see FIG. 4) is selected and a confirmation operation is performed, the designated portion is started to be played. As the playback start time and playback end time of the playback location, any time can be set as long as the program is recorded.

  According to such a configuration, the viewing state of the program can be confirmed after viewing, and a playback location can be easily specified reflecting the viewer's preference, or only a desired location to be viewed can be automatically played back in advance. Can do.

  FIG. 5 shows whether or not each viewing location has been reproduced in the data relating to the reception state of the television broadcast radio wave, the video signal output display state of the television reception unit, and the audio signal output state stored in the external storage unit 14. This is an example in which information to represent is added. The fact that each viewing location has been reproduced is determined by the control unit 15 and stored in the external storage unit 14 when the recording / reproducing unit 18 reproduces the location. In FIG. 5, the portion where the reproduced column is “◯” is reproduced.

  In the format shown in FIG. 4, the recording information is classified according to the change in the reception / output state. In addition to this, by considering the program information, as shown in FIG. 5, it is possible to perform operations in units of programs divided in smaller time units. Further, if information on whether or not the playback has been completed is further considered, it is possible to further subdivide and operate a part of the same program.

  FIG. 6 shows an example in which, as shown in FIG. 5, when information indicating whether or not a viewing location has been reproduced is stored in the storage unit 5, the information is visualized and displayed in the display format. In the example of FIG. 6, the reproduced viewing location is displayed together with the line segment and the notation of its start time and end time. According to such a configuration, since the viewer can discriminate the viewing-and-listening portion that has been reproduced by display, if the reproduced portion is not to be reproduced again, it can be easily excluded and reproduced.

  The present invention relates to a television receiver, a video recording / reproducing apparatus, and a video recording device that can easily specify a reproduction location reflecting the viewer's preference in television viewing and video reproduction, and can automatically reproduce only a desired portion of a program. It can be used industrially as a playback system.
