Note that various programs and some data stored in the storage unit 11 may be stored in a memory provided in the CPU or the like that constitutes the control unit 8.

  The telop generation unit 12 generates telop data TR based on the character data CD supplied from the control unit 8 and supplies it to the video composition unit 6. Here, the telop (TELOP: TELevision Opaque Projector) is a character string or video from one position to another on the screen (for example, from right to left, from left to right, from top to bottom, from below) (Upward, from upper right to lower left, or from lower left to upper right). In this case, the character string moved to the screen edge disappears from the screen, and a new character string is displayed from the opposite screen edge. In addition, the character string or the like may be configured to be updated without updating the character string or the like that is displayed when the user operates the operation unit 10.

  Further, the telop generation unit 12, based on the control signal supplied from the control unit 8, displays the telop display area, the number of lines, the display time, the scroll speed, the display / non-display, and the character string constituting the telop data TR. The display size, display font, and display position are determined. The display area of the telop, the number of lines, the display time, the scrolling speed, display / non-display, the display size of the character string constituting the telop data TR, the display font, and the display position can be arbitrarily set. It may be configured to be changeable by the user operating the operation unit 10.

  Note that some components of the above-described broadcast receiving / recording / reproducing apparatus perform processing related to audio as well as processing related to video, but these processing are not directly related to the present invention. Therefore, the description is omitted. In addition, the above-described broadcast receiving / recording / reproducing apparatus is provided with various components related only to audio in addition to the above-described components, but these components are not directly related to the present invention. Therefore, the description is omitted.

Next, the operation of the broadcast receiving / recording / reproducing apparatus configured as described above will be described. First, while the broadcast receiving / recording / reproducing apparatus is powered on, broadcast signals of all digital broadcast channels (for example, several hundred channels) are simultaneously received by the tuners 2 ₁ to 2 _n via the antenna 1. Each of the tuners 2 ₁ to 2 _n supplies a corresponding transport stream signal TS _{1 to} TS _n to the demultiplexer 3.

The demultiplexer 3 sends MPEG data MDI for each program, which has been separated, extracted, etc., from the transport stream signals TS _{1 to} TS _n supplied from the tuners 2 ₁ to 2 _n to the selector 4 and the program recording unit 9, respectively. At the same time, additional information SI for each program is supplied to the control unit 8 and the program recording unit 9, respectively. The control unit 8 identifies MPEG data MDI for each program to be stored in the recording medium constituting the program recording unit 9 and the additional information SI based on the additional information SI for each program supplied from the demultiplexer 3. Index data ID is generated, and the generated index data ID is sequentially supplied to the program recording unit 9 in association with the corresponding MPEG data MDI and additional information SI together with the control signal. In this case, the control unit 8 stores in the program identification table of the storage unit 11 the correspondence relationship between all the recorded programs of all the channels received by all the tuners 2 ₁ to 2 _n and the index data ID.

  Thereby, the program recording unit 9 converts the MPEG data MDI and the additional information SI supplied from the demultiplexer 3 into the control unit 8 based on the control signal supplied from the control unit 8, for example, as shown in FIG. Are recorded on the recording medium in association with the index data ID supplied from the recording medium. In FIG. 2, k is a natural number. In this case, the additional information SI is recorded on the recording medium for each item, for example, as shown in FIG.

  The process described above is performed in the same manner for the MPEG data MDI and the additional information SI of the program even when the user is viewing an arbitrary program currently being broadcast. Accordingly, in the MPEG decoder 5, the video composition unit 6, the display unit 7, and the telop generation unit 12, the data relating to the program currently being broadcast and the data relating to the program being reproduced read out from the program recording unit 9 are the same. Handled.

  The control unit 8 acquires program information from the additional information SI sequentially supplied from the demultiplexer 3, temporarily stores it in the program information storage area of the storage unit 11, and periodically processes the program information for each channel. The EPG is constructed, updated, and stored in the EPG storage area of the storage unit 11.

  The processing executed by the control unit 8 in such a state will be described with reference to the flowcharts shown in FIGS. First, the control unit 8 proceeds to the process of step S1 shown in FIG. 4, and determines whether or not a currently broadcast program has been selected. The program selection is determined by the control unit 8, for example, when the user selects a channel button, a channel increase button, or a channel decrease button of a remote controller constituting the operation unit 10, and a channel increase button of the main body operation unit constituting the operation unit 10. Whether or not one of the channel decrease buttons is pressed, or when the EPG is displayed on the display constituting the display unit 7, the upper cursor button or the lower cursor of either the remote controller or the main body operation unit This is performed depending on whether or not the enter button is pressed after the cursor (not shown) is moved onto the name of the desired program by operating the button, the left cursor button, and the right cursor button.

  When the user operates the operation unit 10 with the operation method described above to select a broadcast program, the determination result in step S1 is “YES”, and the control unit 8 proceeds to step S2. In step S2, the control unit 8 supplies the selector 4, the MPEG decoder 5 and the video composition unit 6 with control signals for instructing to display the currently broadcast program selected by the user on the display constituting the display unit 7, respectively. After that, the process proceeds to step S3.

  As a result, the selector 4 selects the user from the MPEG data MDI of all the programs of all the channels currently being broadcast supplied from the demultiplexer 3 based on the control signal supplied from the control unit 8. The MPEG data MDI of the selected program is selected and supplied to the MPEG decoder 5 as MPEG data MDS. Therefore, the MPEG decoder 5 decodes the MPEG data MDS supplied from the selector 4 into the video data VD based on the control signal supplied from the control unit 8.

  In this case, it is assumed that the EPG table EPGT is not supplied from the control unit 8 and the telop data TR is not supplied from the telop generation unit 12. Accordingly, the video composition unit 6 supplies the video data VD supplied from the MPEG decoder 5 as it is to the display unit 7 as the composite video data MV based on the control signal supplied from the control unit 8. Thereby, the display unit 7 displays the video of the currently broadcast program selected by the user on the display based on the composite video data MV supplied from the video synthesis unit 6. In step S3, the control unit 8 refers to the EPG storage area of the storage unit 11 and acquires the additional information SI of the currently broadcast program selected by the user, and then proceeds to step S8.

  On the other hand, if the determination result in step S1 is “NO”, that is, if the currently broadcast program is not selected, the control unit 8 proceeds to step S4. In step S4, the control unit 8 determines whether a recorded program already recorded in the program recording unit 9 has been selected. In the determination of the program selection, for example, the control unit 8 displays a list of recorded programs (including thumbnail images) recorded in the program recording unit 9 on the display constituting the display unit 7. The cursor (not shown) is set to the name of a desired program by operating the upper cursor button, the lower cursor button, the left cursor button, or the right cursor button of either the remote controller or the main body operation unit constituting the operation unit 10. This is done depending on whether or not the enter button is pressed after moving the cursor up.

  When the user selects a recorded program by operating the operation unit 10 with the operation method described above, the determination result in step S4 is “YES”, and the control unit 8 proceeds to step S5. On the other hand, when the determination result in step S4 is “NO”, that is, when neither the currently broadcast program nor the recorded program already recorded in the program recording unit 9 is selected, the control unit 8 Return to step S1.

  In step S5, the control unit 8 refers to the program identification table in the storage unit 11, acquires the index data ID corresponding to the recorded program selected by the user, and then proceeds to step S6. In step S6, the control unit 8 supplies the index data ID acquired in the process of step S5 to the program recording unit 9, and instructs to display the recorded program selected by the user on the display constituting the display unit 7. After supplying the control signal to the MPEG decoder 5, the video composition unit 6, and the program recording unit 9, the process proceeds to step S7.

  Accordingly, the program recording unit 9 reads out the MPEG data MDO corresponding to the index data ID based on the control signal and the index data ID supplied from the control unit 8 and supplies the MPEG data MDO to the MPEG decoder 5. Accordingly, the MPEG decoder 5 decodes the MPEG data MDO supplied from the program recording unit 9 into video data VD based on the control signal supplied from the control unit 8.

  In this case, it is assumed that the EPG table EPGT is not supplied from the control unit 8 and the telop data TR is not supplied from the telop generation unit 12. Accordingly, the video composition unit 6 supplies the video data VD supplied from the MPEG decoder 5 as it is to the display unit 7 as the composite video data MV based on the control signal supplied from the control unit 8. Accordingly, the display unit 7 displays the video of the recorded program selected by the user on the display based on the composite video data MV supplied from the video synthesis unit 6.

  In step S7, the control unit 8 supplies the program data recording unit 9 with a control signal instructing to provide the index data ID acquired in the process of step S5 and the additional information SI corresponding to the index data ID. After acquiring the additional information SI corresponding to the index data ID from the recording unit 9, the process proceeds to step S8.

  In step S8, the control unit 8 selects one or more character strings from program information such as program name, program content, program genre, etc. constituting the additional information SI acquired in step 3 or step S7. Is acquired as a keyword, and the process proceeds to step S9. In step S9, the control unit 8 configures the additional information SI for each program stored in the recording medium constituting the program recording unit 9, using one or more character strings acquired in the process of step S8 as keywords. After searching for a character string constituting program information such as program name, program content, program genre, etc., and extracting a matching character string, the process proceeds to step S10.

  In step S10, the control unit 8 creates a list of index data IDs corresponding to programs having matching character strings, stores them in the list storage area of the storage unit 11, and then proceeds to step S11. In step S11, the control unit 8 creates each program stored in the recording medium constituting the program recording unit 9 based on the list created in the process of step S10 and stored in the list storage area of the storage unit 11. Program information constituting the additional information SI is acquired, and character data CD is sequentially generated in the order of the list based on the program information. Next, the control unit 8 sequentially supplies the generated character data CD to the telop generation unit 12, and displays the telop corresponding to the character data CD supplied to the telop generation unit 12 on the display constituting the display unit 7. Is supplied to the video composition unit 6 and the telop generation unit 12, respectively, and the process proceeds to step S12.

  Accordingly, the telop generation unit 12 generates telop data TR corresponding to the character data CD supplied from the control unit 8 based on the control signal supplied from the control unit 8, and supplies it to the video composition unit 6. Therefore, based on the control signal supplied from the control unit 8, the video composition unit 6 combines the video data VD supplied from the MPEG decoder 5 and the telop data TR supplied from the control unit 8, Composite video data MV is generated and supplied to the display unit 7. Based on the composite video data MV supplied from the video composition unit 6, the display unit 7 displays on the display, for example, the video 21 of the currently broadcast program or recorded program selected by the user as shown in FIG. , A program having program information including a character string that matches a character string constituting program information such as the program name, program content, and program genre of the program, and the program already recorded in the program recording unit 9 A video in which a part of the program information is superimposed as a telop 22 is displayed. In this case, the telop 22 is scrolled from right to left on the screen shown in FIG.

  Hereinafter, a display method of the telop 22 will be described using a specific example. First, the currently selected program or recorded program selected by the user is a program with a program frame of “wild world” starting at 7:00 pm on February 3, 20xx (Friday). Suppose the subtitle "Animal" is attached. In the process of step S9 described above, as a result of searching for the character strings “wild world” and “living in the waterside” as keywords, program information of the following programs (1) to (3) is obtained. Assume that the search was successful. In the telop 22 shown in FIG. 7, the double underline is added to the character strings “wild world” and “living in the waterside” to indicate that these character strings are keywords. The meaning of this character string with a double underline is the same in FIG.

(1) January 1st (Wednesday) Wild world "The hunting master who dances in the sky"
(2) Friday, January 16 Insect Kingdom “Splendid insects living in the water”
(3) January 23 (Friday) Wild world "Beasts in the jungle"

  Accordingly, the telop 22 is sequentially changed from the one shown in FIG. 8 (1) to the one shown in FIG. 8 (2) and then to the one shown in FIG. 8 (3). 7 and 8 (1) to (3), the program information (broadcast date, title, subtitle) written in italicized characters is highlighted, and the user operation section This indicates that selection for viewing is possible by 10 operations (described later). On the other hand, in FIG. 7 and FIGS. 8 (1) to (3), program information (broadcast date, title, subtitle) whose characters are written in italicized characters are not highlighted. This means that the user cannot select for viewing even by operating the operation unit 10 (described later). When displaying the availability of selection, in addition to the above-described highlight display, reverse display of characters, change of character color, or the like may be used.

  In addition, a blue key 23, a red key 24, a green key 25, and a yellow key 26 are arranged and displayed in order from the left to the right in the upper part of the screen in FIG. These four keys constitute color keys. The color and arrangement of the color keys correspond to the color and arrangement of color buttons used for digital broadcast EPG and data program operations. This color button is composed of a blue button, a red button, a green button, and a yellow button. The function of each color key will be described below. In FIG. 7, the blue key 23 is indicated by a white rectangle, the red key 24 is indicated by a rectangle with a horizontal stripe on a white background, the green key 25 is indicated by a black rectangle, and the yellow key 26 is indicated by a vertical stripe on a white background. It is shown as a rectangle.

  In step S12 shown in FIG. 4, the control unit 8 determines whether any of the blue key 23, red key 24, green key 25, or yellow key 26 constituting the color key has been operated. If the determination result in step S12 is “NO”, the control unit 8 repeats the determination. The determination of the color key operation is performed by the control unit 8, for example, whether or not the user has pressed any of the blue button, red button, green button, or yellow button of the remote controller constituting the operation unit 10, or display When the blue key 23, the red key 24, the green key 25, and the yellow key 26 are displayed on the display constituting the unit 7, the upper cursor button, the lower cursor button, the left of either the remote controller or the main body operation unit This is performed by operating the cursor button and the right cursor button to move the cursor (not shown) onto one of the color keys and then pressing the enter button.

  When the user operates the color key by the above-described operation method, the determination result in step S12 is “YES”, and the control unit 8 proceeds to step S13 shown in FIG. In step S13, the control unit 8 determines whether or not the blue key is operated. For the determination of the blue key operation, the control unit 8 determines, for example, whether the user has pressed the blue button of the remote control that configures the operation unit 10 or the blue key 23 and red on the display that configures the display unit 7. While the key 24, the green key 25, and the yellow key 26 are displayed, the cursor (by pressing the upper cursor button, the lower cursor button, the left cursor button, or the right cursor button of either the remote controller or the main body operation unit is selected.

If the determination result of step S13 is “YES”, the controller 8 proceeds to step S14.

  In step S14, the control unit 8 supplies the selector 4 or the program recording unit 9 and the MPEG decoder 5 with a control signal for instructing the end of display of the program currently displayed on the display constituting the display unit 7, respectively. Proceed to S15. As a result, when the program being viewed by the user is a program that is currently being broadcast, the selector 4 selects the MPEG data MDI of the program selected in step S2 based on the control signal supplied from the control unit 8. The supply to the MPEG decoder 5 as MPEG data MDS is stopped. The MPEG decoder 5 stops processing such as decoding of the MPEG data MDS supplied from the selector 4 into the video data VD based on the control signal supplied from the control unit 8.

  On the other hand, when the program being viewed by the user is a recorded program already recorded in the program recording unit 9, the program recording unit 9 is supplied first based on the control signal supplied from the control unit 8. The reading of the MPEG data MDO corresponding to the index data ID and the supply to the MPEG decoder 5 are stopped. The MPEG decoder 5 stops processing such as decoding of the MPEG data MDO supplied from the program recording unit 9 into video data VD based on the control signal supplied from the control unit 8.

  In step S15, the control unit 8 stores the index data ID corresponding to the character string related to the recorded program that is included in the telop 22 and can be selected when the user operates the blue key. After obtaining the program identification table 11, the process proceeds to step S <b> 16. In this case, the telop 22 shown in FIG. 7 was given a subtitle “Master of hunting flying in the sky” in the program field “Wild World” broadcast on Wednesday, January 1 at 7:00 pm A character string related to a recorded program is included and is highlighted so that it can be selected.

  In step S16, the control unit 8 supplies the index data ID acquired in the process of step S15 to the program recording unit 9, and instructs to display the recorded program selected by the user on the display constituting the display unit 7. Control signals are supplied to the MPEG decoder 5, the video composition unit 6, and the program recording unit 9, respectively. At the same time, the control unit 8 supplies a control signal instructing to stop displaying the telop based on the character data CD generated in the process of step S11 to the video composition unit 6 and the telop generation unit 12, and then ends the series of processes. .

  Accordingly, the program recording unit 9 reads out the MPEG data MDO corresponding to the index data ID based on the control signal and the index data ID supplied from the control unit 8 and supplies the MPEG data MDO to the MPEG decoder 5. In this case, the program recording unit 9 is a program of the recorded program with the subtitle “Hunting master who dances in the sky” of the “Wild World” program frame broadcast at 7:00 pm on Wednesday, January 1st. The MPEG data MDO is read and supplied to the MPEG decoder 5. Accordingly, the MPEG decoder 5 decodes the MPEG data MDO supplied from the program recording unit 9 into video data VD based on the control signal supplied from the control unit 8.

  In this case, it is assumed that the EPG table EPGT is not supplied from the control unit 8, and as described above, the control unit 8 is instructed to stop displaying the telop based on the character data CD. Accordingly, the video composition unit 6 supplies the video data VD supplied from the MPEG decoder 5 as it is to the display unit 7 as the composite video data MV based on the control signal supplied from the control unit 8. Accordingly, the display unit 7 displays the video of the recorded program selected by the user on the display based on the composite video data MV supplied from the video synthesis unit 6. In this case, the recorded program with the subtitle “Hunter who dances in the sky” of the program frame “Wild World” broadcast at 7:00 pm on Wednesday, January 1 is displayed on the display.

  On the other hand, if the determination result in step S13 is “NO”, that is, if the blue key is not operated, the control unit 8 proceeds to step S17. In step S17, the control unit 8 determines whether or not the red key has been operated. The determination of the red key operation is performed by the control unit 8, for example, whether or not the user has pressed the red button on the remote control that constitutes the operation unit 10, or the blue key 23 or red on the display that constitutes the display unit 7. While the key 24, the green key 25, and the yellow key 26 are displayed, the cursor (by pressing the upper cursor button, the lower cursor button, the left cursor button, or the right cursor button of either the remote controller or the main body operation unit is selected. (Not shown) is moved depending on whether or not the determination button is pressed after the red key 24 is moved. If the determination result of step S17 is “YES”, the controller 8 proceeds to step S18.

  In step S18, the control unit 8 stores the index data ID corresponding to the character string related to the recorded program that is included in the telop 22 and can be selected by being highlighted when the user operates the red key. Obtained by referring to the program identification table of the unit 11. Next, the control unit 8 registers the index data ID of the selected program in a predetermined storage area of the storage unit 11 in order to reproduce the selected program after the currently viewed program ends, Proceed to step S19. In this case, the subtitle “Beast hidden in the jungle” of the “Wild World” program frame broadcast on Friday, January 23 at 7:00 pm was added to the display screen telop (not shown). It is assumed that a character string related to a recorded program is included and is highlighted so that it can be selected.

  In step S19, the control unit 8 determines whether or not the program that the user is currently viewing has ended. This determination is made in the control unit 8 by, for example, a timer provided in the broadcast receiving / recording / reproducing apparatus or a timer configured by hardware or a program (both not shown) (hereinafter collectively referred to as “internal timer”). Or the broadcast end date included in the program information constituting the additional information SI related to the currently broadcast program is counted, or counted from the playback start time of the recorded program. This is performed by determining whether or not the elapsed time of the internal timer that has started the transmission and the broadcast time included in the program information constituting the additional information SI related to the recorded program match. The above-described determination method is the same in the process of step S25 described later. When the determination result of step S19 is “NO”, the control unit 8 repeats the determination. When the program that the user is currently viewing ends, the determination result in step S19 is “YES”, and the control unit 8 proceeds to step S20.

  In step S20, the control unit 8 supplies the index data ID registered in the predetermined storage area of the storage unit 11 in the process of step S18 to the program recording unit 9, and constitutes the display unit 7 with the recorded program selected by the user. A control signal for instructing display on the display is supplied to the MPEG decoder 5, the video composition unit 6, and the program recording unit 9, respectively. At the same time, the control unit 8 supplies a control signal instructing to stop displaying the telop based on the character data CD generated in the process of step S11 to the video composition unit 6 and the telop generation unit 12, and then ends the series of processes. .

  Accordingly, the program recording unit 9 reads out the MPEG data MDO corresponding to the index data ID based on the control signal and the index data ID supplied from the control unit 8 and supplies the MPEG data MDO to the MPEG decoder 5. In this case, the program recording unit 9 records the MPEG data of the recorded program with the subtitle “Beast hidden in the jungle” of the program frame “Wild World” broadcast at 7:00 pm on Friday, January 23. The MDO is read and supplied to the MPEG decoder 5. Accordingly, the MPEG decoder 5 decodes the MPEG data MDO supplied from the program recording unit 9 into video data VD based on the control signal supplied from the control unit 8.

  In this case, it is assumed that the EPG table EPGT is not supplied from the control unit 8, and as described above, the control unit 8 is instructed to stop displaying the telop based on the character data CD. Accordingly, the video composition unit 6 supplies the video data VD supplied from the MPEG decoder 5 as it is to the display unit 7 as the composite video data MV based on the control signal supplied from the control unit 8. Accordingly, the display unit 7 displays the video of the recorded program selected by the user on the display based on the composite video data MV supplied from the video synthesis unit 6. In this case, the recorded program with the subtitle “Beast hidden in the jungle” of the program frame “wild world” broadcast at 7:00 pm on Friday, January 23 is displayed on the display.

  On the other hand, if the determination result in step S17 is “NO”, that is, if the red key is not operated, the control unit 8 proceeds to step S21 shown in FIG. In step S21, the control unit 8 determines whether or not the green key has been operated. For the determination of the green key operation, for example, the control unit 8 determines whether or not the user has pressed the green button of the remote control that configures the operation unit 10, or the blue key 23 or red on the display that configures the display unit 7. While the key 24, the green key 25, and the yellow key 26 are displayed, the cursor (by pressing the upper cursor button, the lower cursor button, the left cursor button, or the right cursor button of either the remote controller or the main body operation unit is selected.

  In step S <b> 22, the control unit 8 acquires the index data ID of the program currently displayed on the display constituting the current display unit 7 with reference to the program identification table of the storage unit 11, and configures the current display unit 7. When the program displayed on the display is a program that is currently being broadcast, time information consisting of a subtraction result obtained by subtracting the current time indicated by the internal timer from the broadcast start time of the program is acquired, and the current display unit 7 is a subtraction result obtained by subtracting the current time indicated by the internal timer from the reproduction start time of the program when the program displayed on the display constituting the program 7 is a recorded program already recorded in the program recording unit 9 Get time information consisting of. Next, the control unit 8 stores the program currently displayed on the display constituting the display unit 7 after the end of the selected program in a predetermined storage area of the storage unit 11 in order to reproduce from the continuation. After registering the acquired index data ID and time information of the program currently displayed on the display constituting the display unit 7, the process proceeds to step S23.

  In step S23, the control unit 8 stores the index data ID corresponding to the character string related to the recorded program that is included in the telop 22 and can be selected when the user operates the green key. After obtaining with reference to the 11 program identification table, the process proceeds to step S24. In this case, the subtitle “Gorgeous insects living in the waterside” of the “Insect Kingdom” program broadcast on Friday, January 16th at 7:00 pm was added to the display screen telop (not shown). It is assumed that a character string related to the recorded program is included and is highlighted so that it can be selected.

  In step S24, the control unit 8 supplies the index data ID acquired in the process of step S23 to the program recording unit 9, and instructs to display the recorded program selected by the user on the display constituting the display unit 7. Control signals are supplied to the MPEG decoder 5, the video composition unit 6, and the program recording unit 9, respectively. At the same time, the control unit 8 supplies the video synthesis unit 6 and the telop generation unit 12 with a control signal for instructing to stop displaying the telop based on the character data CD generated in the process of step S11, and then proceeds to step S25.

  Accordingly, the program recording unit 9 reads out the MPEG data MDO corresponding to the index data ID based on the control signal and the index data ID supplied from the control unit 8 and supplies the MPEG data MDO to the MPEG decoder 5. In this case, the program recording unit 9 is a program of a recorded program with a subtitle “Gorgeous insects living in the waterside” of the program frame “Insect Kingdom” broadcast on Friday, January 16 at 7:00 pm The MPEG data MDO is read and supplied to the MPEG decoder 5. Accordingly, the MPEG decoder 5 decodes the MPEG data MDO supplied from the program recording unit 9 into video data VD based on the control signal supplied from the control unit 8.

  In this case, it is assumed that the EPG table EPGT is not supplied from the control unit 8, and as described above, the control unit 8 is instructed to stop displaying the telop based on the character data CD. Accordingly, the video composition unit 6 supplies the video data VD supplied from the MPEG decoder 5 as it is to the display unit 7 as the composite video data MV based on the control signal supplied from the control unit 8. Accordingly, the display unit 7 displays the video of the recorded program selected by the user on the display based on the composite video data MV supplied from the video synthesis unit 6. In the present case, a recorded program with a subtitle “Gorgeous insects living in the waterside” of the program frame “insect kingdom” broadcast at 7:00 pm on Friday, January 16 is displayed on the display.

  In step S25, the control unit 8 determines whether or not the program that the user is currently viewing has ended. This determination method is the same as that described in step S19. When the determination result of step S25 is “NO”, the control unit 8 repeats the determination. When the program that the user is currently viewing ends, the determination result in step S25 is “YES”, and the control unit 8 proceeds to step S26.

  In step S26, the control unit 8 supplies the index data ID and time information registered in the predetermined storage area of the storage unit 11 in the process of step S22 to the program recording unit 9, and displays the recorded program selected by the user in the display unit. 7 is supplied to the MPEG decoder 5, the video composition unit 6 and the program recording unit 9, respectively. At the same time, the control unit 8 supplies a control signal instructing to stop displaying the telop based on the character data CD generated in the process of step S11 to the video composition unit 6 and the telop generation unit 12, and then ends the series of processes. .

  As a result, the program recording unit 9 determines the MPEG data MDO corresponding to the index data ID based on the control signal, index data ID, and time information supplied from the control unit 8, that is, the time corresponding to the time information, The data is read from minutes after the time when the user operates the green key, and supplied to the MPEG decoder 5. In this case, the program recording unit 9 is a program with a subtitle “Animals living in the jungle and waterside” of the “Wild World” program frame that starts at 7:00 pm on Friday, February 3, 20xx. The MPEG data MDO is read from the time corresponding to the time information, that is, after the time when the user operates the green key, and is supplied to the MPEG decoder 5. Accordingly, the MPEG decoder 5 decodes the MPEG data MDO supplied from the program recording unit 9 into video data VD based on the control signal supplied from the control unit 8.

  In this case, it is assumed that the EPG table EPGT is not supplied from the control unit 8, and as described above, the control unit 8 is instructed to stop displaying the telop based on the character data CD. Accordingly, the video composition unit 6 supplies the video data VD supplied from the MPEG decoder 5 as it is to the display unit 7 as the composite video data MV based on the control signal supplied from the control unit 8. Thereby, the display unit 7 is based on the composite video data MV supplied from the video composition unit 6 and when the recorded program is interrupted by the user viewing the display first and operating the green key.

In this case, among the programs with the subtitle “Animals living in the jungle and waterside” of the program frame “wild world” starting at 7:00 pm on Friday, February 3, 20xx, the user presses the green key. Minutes after the time when was operated are displayed on the display.

  In this case, even when the program for which the user has stopped viewing is being broadcast, the broadcast of the program itself has ended while the recorded program selected by the user is being viewed, or at least the user has Broadcasting for some time after the time when the green key is operated has ended. However, in the broadcast receiving / recording / reproducing apparatus according to the first embodiment, all the channels of the digital broadcast are simultaneously received and all the programs are recorded in the program recording unit 9. Therefore, the process of step S26 differs depending on whether the program that was being viewed when the user operated the green key is currently being broadcast or a recorded program that has already been recorded in the program recording unit 9. There is nothing.

  On the other hand, if the determination result in step S21 is “NO”, that is, if the green key has not been operated, the control unit 8 determines that the yellow key has been operated, and proceeds to step S27. In step S27, the control unit 8 reads out the list of index data IDs corresponding to the programs having the matched character strings created in step S10 and stored in the list storage area of the storage unit 11 to read the video composition unit 6 And a control signal for instructing to display the list on the display constituting the display unit 7 is supplied to the video composition unit 6. At the same time, the control unit 8 supplies a control signal instructing to stop displaying the telop based on the character data CD generated in the process of step S11 to the video composition unit 6 and the telop generation unit 12, and then proceeds to step S28.

  In this case, it is assumed that the EPG table EPGT is not supplied from the control unit 8, and as described above, the control unit 8 is instructed to stop displaying the telop based on the character data CD. Therefore, based on the control signal supplied from the control unit 8, the video synthesis unit 6 combines the video data VD supplied from the MPEG decoder 5 and the index data ID list supplied from the control unit 8. Then, the composite video data MV is generated and supplied to the display unit 7.
