Description

  The present invention relates to a digital broadcast receiving apparatus, a digital broadcast recording / reproducing apparatus, a viewing program receiving method, and a viewing recorded data reproducing method for receiving a digital broadcast and returning to a program or recorded data that has been viewed.

  Toward the end of analog broadcasting in July 2011, digital broadcast receivers that receive digital broadcasts using satellites and terrestrial waves have become widespread. The digital broadcast receiving apparatus selects an arbitrary broadcast wave from a plurality of broadcast waves received through a dedicated antenna using a tuner. Since this broadcast wave includes a plurality of channels, an arbitrary channel is further selected by a demultiplexer (DEMUX), a video / audio signal is separated from a digital signal of the selected channel, and decoded and output by a decoder. Is done.

  In digital broadcasting, in addition to transmitting video and audio in the same way as conventional analog broadcasting, program information using an electronic program guide (EPG) is also transmitted. This program information includes various information such as channel name (broadcasting station name), program name, program start / end time, program broadcast time length, program content information, program genre information, etc. Using the EPG display function, an arbitrary program can be selected and viewed from multi-channel broadcasting.

Using this program information and viewing history information, it is possible to return to the program that the user has watched before, and techniques relating to this have been developed.
For example, in data broadcasting, the viewing history of a program that was viewed is stored, the program data is stored, and if the user wants to view the program that the user has viewed again, the data broadcasting history operation window is displayed and selected from the window A technique capable of viewing the program is disclosed (see, for example, Patent Document 1).

  In addition, for example, when displaying an EPG, a technique is disclosed in which a program with a viewing history is displayed in a different color so that the program can be viewed and returned to the original program (for example, Patent Document 2). reference).

FIG. 13 is a functional block diagram of a conventional digital broadcast receiving apparatus 61 as disclosed in Patent Document 2, for example.
A digital broadcast signal is received by the antenna 61. From the received signal, a tuner 62 extracts a signal of a specific frequency from a high frequency digital modulation signal including video and audio. Further, the selected digital modulation signal is demodulated and a transport stream (TS) is output. The TS is separated by a demultiplexer (DEMUX) 63 into MPEG2 (Moving Picture Experts Group 2) video stream, audio stream, and PSI / SI (Program Specific Information / Service Information). A plurality of channels are multiplexed in the TS. SI includes program information. The video stream and the audio stream are decoded by the AV decoder 64, the generated video data is output to the video processing circuit 65, and the audio data is output to the audio processing circuit 66. The video processing circuit 65 performs D / A conversion of the video data, for example, converts it into a composite signal, and sends a signal to the display 76a of the monitor 76 via the video output circuit 67 and the AV output terminal 69 to display the video. The audio processing circuit 66 performs D / A conversion on the audio data, sends a signal through the audio output circuit 68 and the AV output terminal 69, and causes the speaker 76b of the monitor 76 to generate sound.

  An OSD (On-Screen Display) circuit 72 outputs video data based on character information and color information instructed to be output from the CPU 73 to the adder 80. The OSD circuit 72 can perform EPG display based on the program information received by the CPU 73. When signal light indicating a command corresponding to a key is transmitted from the remote control transmitter 70, the remote control light receiver 71 receives the signal light, converts it into an electrical signal, and gives it to the CPU 73. Using this remote control transmitter 70, the user can check the viewing history on the EPG screen. The nonvolatile memory 74 stores viewing history information and the like in addition to data (program information and the like) for displaying the EPG screen. The CPU 73 stores the viewing history information in the nonvolatile memory 74 every time the channel selection process is performed. The EPG information and viewing history information stored in the nonvolatile memory 74 can be displayed in an overlapping manner by using the OSD 72 and the adder 80 via the CPU 73.

  As a means for recording a broadcast program, a broadcast program recording device provided with a recording medium has recently been replaced by a video deck and has become widespread. The recording media in this case are internal or external hard disks, DVD (± R, RE, RAM, VR), HD-DVD (R, RE), Blu-ray Disc (R, RE), flash memory , SD card and so on.

In these broadcast program recording devices, a list of recorded data can be displayed as a list or a thumbnail, and a user can select and view arbitrary recorded data from the list by a general operation method. is there.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First embodiment)
FIG. 1 is a functional block diagram of a digital broadcast receiving apparatus according to this embodiment of the present invention.

  The digital broadcast receiving apparatus 1 extracts a signal of a specific frequency from a digital broadcast signal received from an antenna 2, demodulates a selected digital modulation signal, and outputs a TS, and an MPEG2 video stream and audio stream And a demultiplexer unit (hereinafter referred to as “DEMUX unit”) 4 that separates into PSI / SI, an AV decoder unit 5 that decodes a stream separated by the DEMUX unit 4, and video data decoded by the AV decoder unit 5 The video unit 6 processed for output, the audio unit 7 that processes audio data decoded by the AV decoder unit 5, and the output unit 8 that synchronizes and outputs the data processed by the video unit 6 and audio unit 7. And various controls of the input unit 9 that receives an input signal from the remote controller 20 and the digital broadcast receiver 1. Search is performed for the control unit 10, the channel selection unit 11 that transmits the channel selection information sent from the control unit 10 to the tuner unit 3, the history information storage unit 12 that stores the viewing history information, and the history information storage unit 12. The search unit 13 is configured to include an OSD circuit 14 and an adder 15.

  The video data output from the output unit 8 is output from the display 21 such as a TV, and the audio data is output from the speaker 22.

FIG. 2 is a flowchart showing the flow of processing of digital broadcast reception.
When the power of the digital broadcast receiving apparatus 1 is turned on with the remote controller 20, the control unit 10 outputs the channel information viewed last time to the tuner unit 3 via the channel selection unit 11, and the tuner unit 3 specifies the channel information. By extracting the frequency signal, the program of the channel at the time of the previous viewing is output. When the user inputs an arbitrary channel (S1), channel information is transmitted from the input unit 9 to the control unit 10, and channel information is sent from the tuning unit 11 to the tuner unit 3 under the control of the control unit 10 (S2).

  Further, the control unit 10 stores channel information and the like in the history information storage unit 12 (S3).

FIG. 3 is an example of viewing history data of the history information storage unit 12.
For example, data such as a title, a channel, a genre, a viewing start time, a viewing end time, a viewing time length, a program content that briefly introduces the content of the program, and the like are stored.

  The viewing history data may be stored under the condition that the history information storage unit 12 is stored until the capacity of the history information storage unit 12 becomes full, and the oldest one is deleted when the capacity is full. A storage period is set in advance. It is also possible to store only during that period. Alternatively, various storage conditions such as storage until the digital broadcast receiving apparatus 1 is turned off can be employed. At this time, information on whether or not the program table (EPG) is passed is also stored together with the channel information. By making it possible to identify whether or not the program guide has been passed, it is possible to set, for example, not to pass through the program guide as a program search condition. For example, when the user wants to watch a program immediately after the power is turned on, the user may search on the condition that the program does not go through the program guide.

  On the other hand, the antenna 2 receives the digital broadcast signal, and the tuner unit 3 that has obtained the output from the antenna 2 takes out a signal of a specific frequency based on the channel information from the channel selection unit 11, demodulates the selected digital modulation signal, TS is output to the DEMUX unit 4 (S4). The DEMUX unit 4 separates the TS into a video stream and an audio stream (S5), is decoded by the AV decoder unit 5 (S6), and the generated video data is output to the video unit 6 and the audio data is output to the audio unit 7. Then, the video data is output from the TV display 21 and the audio data is output from the speaker 22 via the output unit 8 (S8), and this process ends.

FIG. 4 is a flowchart showing a flow of processing for the user to select a desired program using history information.
When the user views a plurality of programs and wants to return to any of the programs that have been viewed so far, for example, the user presses a “return” button on the remote controller 20 and transmits a signal to the input unit 9 (S11). . Note that a code is added to the “return” button and an instruction is assigned so that a signal instructing to shift to the program that was previously viewed can be transmitted to the digital broadcast receiving apparatus 1. In the case of a recorder or the like, if another command has already been assigned to the “Return” button, long press and a combination with another key (for example, “Menu” + “Back” etc.) It may be possible to instruct to shift to the program that was being performed.

  The control unit 10 that has obtained the output of the signal from the input unit 9 outputs a control signal to the search unit 8 so as to search, for example, program information that was viewed immediately before the program that is currently viewed (S12). ).

  Upon receiving an instruction from the control unit 10, the search unit 13 searches the history information storage unit 12 for the corresponding stored data, and returns the channel information of the program that was previously viewed to the control unit 10 (S13). The control unit 10 that has obtained the search result outputs the channel information to the channel selection unit 11 (S14), so that the program display processing as shown in S4 to S8 in FIG. 2 is performed. The program that has been displayed is displayed (S15).

  Thereafter, the control unit 10 determines whether or not a signal for selecting a program from the input unit 9, in the case of this example, a signal for selecting the previous program is input (S <b> 16). When a signal is transmitted from the input unit 9 to return to the previous program (“YES” in S16), the process returns to S12, and the control unit 10 controls the search unit 13.

  When there is no signal from the input unit 9 (“NO” in S16), for example, when there is no input within a predetermined time, or when a signal to end the processing is transmitted from the input unit 9, the control unit 10 This process is terminated.

  As described above, when the user subsequently presses the “return” button on the remote controller 20, it is possible to return to the viewing history order and view the program.

  When a command other than “return”, for example, “previous”, is assigned to return to the previously displayed program as the viewing history, and the previous candidate program is displayed in the order of viewing history. You may be allowed to return to

  Further, instead of returning to the previous program as described above or sequentially returning, it is possible to input various search conditions and return to the program desired by the user.

  For example, a condition setting GUI (Graphical User Interface) for returning to a program is displayed on the display 21, a condition is arbitrarily input by the remote controller 20, a program is searched, and a jump to (skip) an arbitrary program is returned. It is also possible to watch.

  FIG. 5 is a flowchart showing an example of a flow of program search processing by condition input.

  When the power of the broadcast receiving apparatus 1 is turned on and the user presses a remote control button, for example, a “return” button assigned to select a previously viewed program while viewing the program (S21). The signal is transmitted from the input unit 9 to the control unit 10, and the control unit 10 instructs the adder 15 to output the GUI data for searching the program to be returned to the OSD circuit 14, and the GUI data is added. The video data is output from the AV decoder by the device 15 and displayed on the display 21 via the video unit 6 and the output unit 8 (S22). The user sees the program search screen and performs input using the remote controller 20. For example, the user presses the up / down button or the enter button or directly inputs characters, and the conditions for searching the viewed program are selected.

  The control unit 10 repeatedly determines whether or not a signal is transmitted from the input unit 9 (S23). When the control unit 10 determines that there is an input (“YES” in S23), the control unit 10 determines which search condition the signal is for. Judge whether it is a thing.

  First, the control unit 10 determines whether the signal from the input unit 9 is, for example, a selection of the previous viewing program (S24). If the signal selects the previous viewing program (“YES” in S24), the control unit 10 controls the search unit 13 as described in S12 to S15 in FIG. The channel information of the previous viewing program is acquired from the storage unit 12 and displayed (S25), and this process ends.

  If the signal does not select the previous viewing program (“NO” in S24), the control unit 10 confirms whether or not the program table has been passed (S26), and then the viewing time length is also checked. (S27), if it is not for the viewing time length (“NO” in S27), the control unit 10 further relates to the viewing start time (S28) or not for the viewing start time (S28). "NO"), whether it is about the viewing end time (S29), if it is not about the viewing end time ("NO" in S29), is it within a range that is back a predetermined time from the current time (S30), predetermined time If it is not within the retroactive range (“NO” in S30), a determination is made as to whether a keyword has been designated (S31).

  If it corresponds to each determination (“YES” in any of S26 to S31), the control unit 10 outputs the search condition and the designated numerical value or character information to the search unit 13, and the search unit 13 stores the history information storage unit. 12 searches are performed, and it is determined whether the search results correspond to a plurality of programs (S32).

  Note that the designated numerical value or character information is the case where the viewing time length in S27 and the time range in S30 are designated, the numerical value indicating the length of time, the viewing start time in S28, and the viewing end time in S29. Is a numerical value indicating time, and in the case of keyword search in S31, it is character information.

  If the search result does not correspond to a plurality of programs (“NO” in S32), the control unit 10 proceeds to the process of S25.

  If the search result corresponds to a plurality of programs (“YES” in S32), the control unit 10 selects, for example, a program with a new viewing time and selects channel information of the program according to a predetermined rule set. By outputting to the local part 11 and performing the processing of S14 and S15 in FIG. 4, one of the corresponding programs is displayed (S33). The predetermined rule for selecting a program may be set by the user operating the remote controller 20 or the like and inputting from the input unit 9, and the control unit 10 may be set in the search unit 13, or may be set in advance when the product is manufactured. Also good.

  When the displayed program is not a desired program, the user presses, for example, a “return” button on the remote controller 20 to display another candidate program.

  The control unit 10 determines whether or not a signal indicating another candidate selection such as “return” is input from the input unit 9 within a predetermined time counted by a counter or the like (S34). If no input is made within the predetermined time (“NO” in S34), this process is terminated.

  If "return" is input ("YES" in S34), the control unit 10 determines whether all the search result programs are displayed (S35). If not all are displayed ("NO" in S35). ]), The next candidate program is selected from the search results, and the process returns to S33.

  When all the search result programs are displayed (“YES” in S35), the control unit 10 returns to the process of S22 and causes the display 21 to display the program search GUI again.

  When there are a plurality of search results in this way, candidates can be displayed one after another with the “Return” button until the corresponding program is displayed, and then returned in order. Moreover, when all the programs are displayed and there is no corresponding program, it is also possible to re-enter an arbitrary condition and perform a search again.

  In addition, if the determination in S31 is NO and none of the set search conditions is satisfied, the process returns to S22, and the program search GUI is displayed again on the display 21.

  In addition to the above-described conditions, in S22, it may be possible to set search conditions such as AND or OR search for a plurality of conditions or search for the first program immediately after the power is turned on.

  As described above, the user can view a desired program by displaying a previously viewed program according to a predetermined rule without storing a program title or the like.

  In the above description, the button operation of the remote controller 20 has been described, but a touch panel function or a pen input function may be added to the remote controller 20 to input a program search condition.

  In addition, the items of the search conditions (S24, S26 to S31) and the determination order of the search conditions shown in the flowchart of FIG. 5 are examples, and some of the search conditions are set in this, or the order is set differently. The actions and effects on the problems of the present invention are the same.

  If the broadcast time of the corresponding program has ended as a result of the search, the control unit 10 controls the OSD circuit 14 to indicate that the broadcast has ended, the program name, the channel number, the program content, etc. May be displayed.

  In the case of digital broadcast reception as in the present embodiment, there is a time lag between selecting a program from the program guide and displaying it. A part of the broadcast data when the program is displayed may be registered in the history information storage unit 12 in a state associated with the viewing history information. In this case, the control unit 10 acquires data at the time of broadcasting from the DEMUX unit 4 and registers it in the history information storage unit 12.

  When there is an input for selecting a program, the control unit 10 performs a search by controlling the search unit 13 to check whether there is a viewing history of the selected program. Output to the AV decoder unit 5. The AV decoder unit 5 outputs the data from the history information storage unit 12 until the broadcast data of the selected program is received and acquired.

  The broadcast data displayed at the time lag described above may be, for example, from the beginning of the program or from 5 seconds before the end of the program.

  Since the broadcast data stored in the history information storage unit 12 usually has a time lag of several seconds, it is not necessary to store all of the broadcast data, and the storage capacity can be reduced by using only a part.

FIG. 6 is a diagram for illustrating an operation example in the present embodiment.
This operation example will be described with reference to the flowchart of FIG.

  First, when a user watches a program for 20 minutes as shown in FIG. 6 (a), the program table is displayed as shown in FIG. 6 (b), a different program 30 is selected, and the program shown in FIG. 6 (c) is selected. I watched 5 minutes of the different program selected. Further, the program table is displayed as shown in FIG. 6D, a different program 31 is selected, and the selected program is viewed for 10 minutes as shown in FIG.

  In this case, it is assumed that the user wants to return to the original program for viewing but does not remember the program name or channel. The user presses, for example, a “return” button on the remote controller 20, and transmits a signal to the digital broadcast receiving apparatus 1 to return to the previously viewed program (S21). A signal is transmitted from the input unit 9 to the control unit 10, and the control unit 10 controls the OSD circuit 14 to display a program search screen as shown in FIG. 6 (f) (S22).

  It is assumed that the user selects “view the longest” from the pull-down menu 32 as a search condition and selects and inputs the “return” button 33.

  In the program search screen, in addition to the pull-down menu 32 as described above, pull-down menus such as “3 minutes”, “5 minutes”, “10 minutes”, and “30 minutes” for setting the viewing time length. May be displayed. Also, for other items for setting time and general items such as genres for keywords, several candidates may be prepared and used as a pull-down menu. Of course, direct input may be used instead of the pull-down menu.

  The control unit 10 recognizes a signal related to program selection via the input unit 9 ("YES" in S23), and determines whether the signal selects the previous viewing program (S24).

  Since the signal selects the program that has been viewed the longest (“NO” in S24 and S26), the control unit 10 determines whether the signal is the viewing program length (S27). Since it corresponds ("YES" in S27), the control unit 10 controls the search unit 13 to search the history information storage unit 12 for the program that has been viewed the longest. Since the search result is the program that has been viewed for the longest time, there is only one corresponding program (“NO” in S32), and the control unit 10 outputs the channel information of the search result to the channel selection unit 11, and FIG. The selected program is displayed (S25), and this process is terminated.

  As described above, the user can search and view a desired program in various ways even if he / she does not remember the program name or channel of the program he / she wants to return to.

  The list creation unit 44 generates a broadcast data recording list from the broadcast data information acquired from the recording unit 42 under the control of the control unit 43.

FIG. 8 is a flowchart showing the flow of the recorded data reproduction process.
When the recorded data list display is selected by the remote controller 20, a command is sent from the input unit 9 to the control unit 43 (S41), and the control unit 43 controls the list creation unit 44 to generate a recorded data list. The list creation unit 44 obtains recording data information from the recording unit 42, generates recording data list information, and outputs it to the control unit 43. The control unit 43 outputs the recorded data list information to the OSD circuit 14, and the recorded data list is displayed on the display 21 as described in the first embodiment (S42).

  The control unit 43 repeats the determination of whether recording data is selected from the input unit 9 (S43). When the recording data selection is input, the control unit 43 stores the information for specifying the recording data in the history information storage unit 46 (S44), and outputs the information for specifying the recording data to the DEMUX unit 45, The DEMUX unit 45 acquires the recording data from the recording unit 42 and outputs it to the AV decoder unit 5 (S45). The subsequent processing of S46 to S48 is the same as S6 to S8 of FIG.

  Information that identifies the recorded video data that has been viewed through the above processing is stored in the history information storage unit 46.

FIG. 9 is an example of viewing history data in the history information storage unit 46.
Basically, it is the same as in the first embodiment. The difference is that in addition to the information of the program that has been viewed, the information of the recorded data that has been viewed is also stored. For example, information such as recording date and time (recording start time, recording end time), recording time length, recording destination, recording mode, recording or program, and the like. Information on the recording data is acquired from the recording data list information generated by the list creation unit 44. For example, as shown in FIG. 9, when a program D is a reproduction of recorded data, a recording or program column is provided, and identification information that can distinguish between viewing a real-time program and viewing a recorded program is input. In FIG. 9, four viewing histories are described as an example, but can be recorded as long as the capacity is allowable.

  FIG. 10 is a flowchart illustrating an example of a flow of viewing data search processing by condition input.

  Since S51 to S53 in FIG. 10 are the same as S11 to 13 in FIG. 4 and S57 and S58 in FIG. 10 are the same as S15 and S16 in FIG. 4, description thereof will be omitted and only different processing will be described.

  When the control unit 43 obtains the search result from the search unit 13, it determines whether it is broadcast program information or recorded data information (S54). If the search result is broadcast program information (“NO” in S54), the control unit 43 outputs channel information to the channel selection unit 11 (S55) to display the program. If the search result is recorded data information (“YES” in S54), the control unit 43 outputs the recorded data information to the DEMUX unit 45 (S56), and displays the recorded data.

  By performing the processing as described above, even if the previously viewed program is real-time broadcast data or recorded data, it can be displayed again only by the user instructing “return” with the remote control. It becomes possible.

FIG. 11 is a flowchart showing an example of a flow of viewing data search processing by condition input. The flow of processing is the same as that in FIG. 5 of the first embodiment.
FIG. 12 is a diagram for illustrating an operation example in the present embodiment. An example of this operation will be described with reference to the flowchart of FIG.

  First, the user displayed the recorded data list as shown in FIG. 12A, selected the recorded data 50, and viewed the selected recorded data as shown in FIG. Further, the recorded data list is displayed as shown in FIG. 12C, different recorded data 51 is selected, and the selected recorded data is viewed as shown in FIG. Thereafter, it is assumed that the program table is displayed as shown in FIG. 12E and a program 52 is viewed as shown in FIG.

  In this case, it is assumed that the user wants to return to the original recorded data and views but the user does not remember the recorded data name. The user presses, for example, a “return” button on the remote controller 20, and transmits a signal to the digital broadcast receiving apparatus 41 to return to the previously viewed data (S61). A signal is transmitted from the input unit 9 to the control unit 43, and the control unit 43 controls the OSD circuit 14 to display a viewing data search screen as shown in FIG. 12G (S62).

  It is assumed that the user selects “keyword” from the pull-down menu 53 as a search condition, inputs “brown dog” in the input field 54, and selects and inputs the “return” button 55.

  It should be noted that on the viewing data search screen, several candidates for general items such as genres regarding keywords may be prepared and a pull-down menu may be displayed. In addition, items for setting other times may be used as pull-down menus. Of course, direct input may be used instead of the pull-down menu.

  Through the input unit 9, the control unit 43 recognizes a signal related to viewing data selection ("YES" in S63), and determines whether the signal selects the previous viewing program (S64).

  Since the signal is selected by a keyword (“NO” in S64 and S67 to S70, and whether it is via a program guide in S66), the control unit 43 determines whether the signal is for a keyword (S71). . Since it corresponds ("YES" in S71), the control unit 10 controls the search unit 13 to perform keyword search from the viewing history data stored in the history information storage unit 46, for example, as shown in FIG. . If the search result is one piece of viewing data (“NO” in S72), the control unit 43 displays the selected viewing data (S65). If the search result corresponds to a plurality of viewing data (“YES” in S72), the control unit 43 displays the data viewed based on the set rule (S73). When an input for displaying another viewing data candidate is performed by the user's remote control 20 operation, the control unit 43 displays all the corresponding data until it is displayed. In the case of the example in FIG. 12, since the keyword “brown dog” corresponds to only one record data, the control unit 43 outputs the record data information to the DEMUX unit 45 and displays the record data in FIG. As described above, the recorded data 50 is reproduced, and this processing is terminated.

  As described above, the user can search for and view desired viewing data without having to remember the data name, channel, or the like of viewing data to be returned.

  Also, in the past, when viewing recorded data and wanting to view previously recorded data again, it is necessary to display the recorded data list once and select the desired recorded data. However, in the present invention, when it is desired to return to the recorded data that was previously viewed, for example, it is possible to view by simply selecting the “Return” button on the remote control, which is convenient for the user. Increase.

  In this embodiment, the digital broadcast receiving apparatus with a recording function has been described as an example. However, the digital broadcast receiving function and the recording / playback function may be realized by separate apparatuses.

  Further, the present invention is not limited to receiving digital broadcasts, and may be an apparatus that receives content via a network, and may store a history of reproduced content and return to the content that was originally viewed.

  The digital broadcast receiving apparatus, digital broadcast recording apparatus, and viewing data display method of the present invention are not limited to the above illustrated examples, and various modifications can be made without departing from the scope of the present invention. Of course.
