Description

  The present invention relates to a recording / reproducing apparatus and a recording / reproducing method for recording / reproducing a broadcast program. The present invention also relates to a television receiver including such a recording / reproducing apparatus, a program for operating a computer as such a recording / reproducing apparatus, and a recording medium on which such a program is recorded.

  As recording media such as HD drives have increased in capacity, recording and playback devices capable of recording a large number of broadcast programs have become widespread. In these recording / playback apparatuses, in addition to conventional recording methods such as manual recording (sometimes referred to as “one-shot recording”) and scheduled recording, automatic recording that automatically records broadcast programs that match user preferences Recording using a new recording method (sometimes referred to as “regular recording”) is possible. With automatic recording, users can enjoy a program that matches their preferences after the end of broadcasting without having to select a program to be viewed from the electronic program guide in order to make a recording reservation.

  As techniques related to automatic recording, for example, those described in Patent Documents 1 and 2 are known. The technique described in Patent Document 1 prevents automatic recording of a program being viewed by a user. The technique described in Japanese Patent Laid-Open No. 2004-228561 is designed to allow easy reproduction of a next broadcast program if it is recorded when viewing a recorded program constituting the series.

Further, when the BD drive is connected to the television 1 by USB, this BD drive (external BD drive) may be used for storing recorded programs. When an optical disk drive other than the BD drive is connected by USB, the optical disk drive may use a recording medium for storing a recorded program, or a recording medium such as a USB flash memory may be used for storing a recorded program. May be. In short, any recording medium may be used as long as it can store recorded programs.

  Further, an interface for connecting an external recording device (in this embodiment, the HD drive 2) used for storing a recorded program is not limited to the USB interface 115. That is, the USB interface 115 is, for example, a wired connection interface such as ATA (Advanced Technology Attachment), ATAPI (ATA Packet Interface), IEEE 1394, HDMI (High-Definition Multimedia Interface), and LAN, or wireless such as IEEE 80211. It can be replaced with a connection interface. When an SD card is connected, this SD card may be used for storing recorded programs. In short, any interface for connecting an external recording device may be used as long as it can transmit a recorded program.

  In the present embodiment, as a terrestrial digital broadcasting method, a method of multiplexing MPEG2 streams (ATSC method in the United States, ISDB-T method in Japan, etc.) is assumed, but the present invention is not limited to this. It is not something. That is, for example, instead of multiplexing MPEG2 streams, the present invention can also be applied to a system that multiplexes MPEG4 streams and the like (DVB-T / DVB-T2 system in Europe, etc.). In the latter case, the demodulated MPEG4 stream may be recorded on the recording medium as it is, or the demodulated MPEG4 stream may be converted into an MPEG2 stream and recorded on the recording medium.

(Electronic program guide)
Next, an electronic program guide displayed on the LCD 110 by the television 1 will be described with reference to FIG. FIG. 2 is a diagram showing an electronic program guide 30 displayed on the LCD 110 by the television 1. The electronic program guide 30 has a recommended program column 32 for displaying a list of recommended programs selected by the television 1 from among the programs being broadcast and scheduled to be broadcast in the broadcast program column 31 for displaying a list of broadcast programs scheduled to be broadcast. It is added.

  The broadcast program column 31 includes a plurality of columns 31a to 31e corresponding to the channels A to E. In each of these columns 31a to 31e, cells representing each broadcast program broadcast via the channel are arranged along the time axis. For example, cells a1 to a3 representing broadcast programs broadcast via channel A are arranged in the first column 31a along the time axis, and broadcasts are performed via channel B in the second column 31b. Cells b1 to b3 representing the broadcast programs to be played are arranged along the time axis. In each cell constituting the broadcast program column 31, meta information (title, genre, content, etc.) regarding the corresponding broadcast program is displayed.

  The recommended program column 32 is composed of one column in which cells r1 to r3 representing each recommended program are arranged along the time axis. In each cell constituting the recommended program column 32, meta information such as a title, a genre, and contents regarding the corresponding recommended program is displayed as in each cell constituting the broadcast program column 31. Here, the recommended program refers to a program selected by the television 1 from the broadcast programs listed in the broadcast program column 31 as a broadcast program that matches the viewer's preference. In the example shown in FIG. 2, a broadcast program broadcast from 19:00 to 19:30 on channel A, a broadcast program broadcast from 20:00 to 20:45 on channel C, and 21:00 on channel B Broadcast programs to be broadcast from 00 minutes to 22:00 are selected, and these broadcast programs are listed as recommended programs in the cells R1 to R3, respectively. The recommended program is sometimes called a “regular program”.

  As a method for the television 1 to select a recommended program, for example, the following method (1) or (2) may be mentioned. However, the method by which the television 1 selects the recommended program is not limited to the method (1) or (2), and may be replaced with another known method.

  (1) For each broadcast program posted in the broadcast program column 31, it is determined whether or not the broadcast program is a program viewed last week. Then, the broadcast program determined to be the program viewed last week is selected as the recommended program. Here, whether or not the broadcast program having the broadcast channel x, the broadcast day y, the broadcast start time t1, and the broadcast end time t2 is the program viewed last week is determined from, for example, the time t1 of the previous week y. The determination can be made based on whether or not the time t during which the channel x has been selected until the time t2 occupies half or more of the broadcast time (t2-t1). In this example, the broadcast using the program viewed one week ago as the recommended program has been described. In addition to the program viewed one week ago, the program viewed two weeks ago, the program viewed three weeks ago,... Also, a method may be adopted in which a program viewed N weeks ago (that is, a broadcast program viewed up to N weeks ago) is used as a recommended program.

  (2) For each broadcast program listed in the broadcast program column 31, a score corresponding to the viewing frequency of the broadcast channel of the broadcast program and the viewing frequency of the genre of the broadcast program is calculated. Broadcast programs broadcast in each time zone (for example, 0:00 to 1:00, 1:00 to 2:00, ..., and 23:00 to 24:00) The broadcast program with the highest score is selected as the recommended program. Here, the score of a broadcast program whose broadcast channel is x and genre is z can be calculated, for example, by taking the average of the viewing frequency of channel x and the viewing frequency of genre z. The viewing frequency of channel x is calculated by, for example, K / N, where M is the total number of programs viewed within a predetermined period (for example, the last week), and K is the number of programs whose broadcast channel is x. Can do. The viewing frequency of genre z is calculated by, for example, L / N, where M is the total number of programs viewed within a predetermined period (for example, the last week), and L is the number of programs whose genre is z. be able to.

  In order to realize such display of the electronic program guide 30, the CPU 118 of the television 1 creates a broadcast program table from the EPG data, and stores the created broadcast program table in the RAM 117. Here, the broadcast program table represents the broadcast program column 31 of the electronic program guide 30 as computer-readable table data. The CPU 118 of the television 1 creates a recommended program table from the viewing history and the broadcast program table, and stores the created recommended program table in the RAM 117. Here, the recommended program table represents the recommended program column 32 of the electronic program guide 30 as computer-readable table data.

  An example of the recommended program table is shown in the table below. As shown in the table below, each recommended program includes (1) its program ID, (2) its broadcast start time, (3) its broadcast end time, (4) its broadcast channel, and (5) The meta information is registered. In the table below, meta information xxx represents meta information such as title, genre, and content displayed in the corresponding cell r1 of the electronic program guide 30.

  When the CPU 118 receives a user operation for instructing display of the electronic program guide 30, the CPU 118 creates OSD data representing the electronic program guide 30 from the broadcast program table and the recommended program table stored in the RAM 117, and the created OSD data is stored in the OSD data. This is provided to the generation unit 108. The OSD generation unit 108 renders the electronic program guide 30 (OSD image) from the OSD data. In this way, display of the electronic program guide 30 is realized.

  Further, the television 1 has a recommended program channel selection function for automatically selecting a recommended program and a recommended program recording function for automatically recording the recommended program. The recommended program channel selection function and the recommended program recording function are realized based on the above-described recommended program table as described below. Note that the recommended program tuning function and the recommended program recording function may be referred to as a “regular program tuning” function and a “regular recording” function, respectively.

  When the user presses a button (hereinafter referred to as a recommended program channel selection button) for enabling the recommended program channel selection function of the television 1 provided on the remote control, the television 1 performs the recommended program channel selection function. To enable. In order to realize the recommended program channel selection function, the CPU 118 switches the channel selection target channel of the terrestrial digital broadcast tuner 102 based on the recommended program table. Specifically, the broadcast start time of each recommended program registered in the recommended program table and the current time t are periodically compared. Then, when the broadcast start time of the recommended program with the current time t is reached, the channel to be selected of the terrestrial digital broadcast tuner 102 is switched to the broadcast channel of the recommended program.

  According to the example shown in Table 1, if the recommended program channel selection function has been activated after 19:00, the CPU 118 selects the digital terrestrial broadcast tuner 102 at 19:00. Switch the target channel to channel A, switch the channel to be selected for digital terrestrial broadcasting tuner 102 to channel C at 20:00, and select the channel to be selected for digital terrestrial broadcast tuner 102 at 21:00. Switch to channel B. Thereby, each recommended program registered in the recommended program table is automatically selected.

  If the automatic channel selection button on the remote control is pressed between 19:00 and 19:30 and the recommended program channel selection function is activated, the CPU 118 activates the recommended program channel selection function. At this point, the channel to be selected by the terrestrial digital broadcast tuner 102 is switched to channel A. Further, the CPU 118 activates the recommended program channel selection function when the automatic program selection button on the remote controller is pressed between 20:00 and 20:45, and the recommended program channel selection function is activated. At this point, the channel to be selected by the terrestrial digital broadcast tuner 102 is switched to channel C. Further, when the automatic program selection button on the remote controller is pressed between 21:00 and 22:00 and the recommended program channel selection function is activated, the CPU 118 activates the recommended program channel selection function. At this point, the channel to be selected by the terrestrial digital broadcast tuner 102 is switched to channel B.

  The automatic channel selection mode may adopt a configuration that ends when one recommended program ends, or may adopt a configuration that continues until the automatic channel selection release button of the remote controller is pressed.

  In order to realize the recommended program recording function, the CPU 118 switches the recording target channel of the terrestrial digital broadcast tuner 102 based on the recommended program table, and gives an automatic recording start instruction and an automatic recording stop instruction to the recording unit 104a. More specifically, the CPU 118 periodically compares the broadcast start time of each recommended program registered in the recommended program table with the current time t. Then, when the broadcast start time of a recommended program with the current time t is reached, an automatic recording start instruction is given to the recording unit 104a. Further, when the current time t reaches the broadcast end time of the recommended program, an automatic recording stop instruction is given to the recording unit 104a.

  Speaking of the example shown in Table 1, the CPU 118 gives an automatic recording start instruction to the recording unit 104a at 19:00. Then, at 19:30, an instruction to stop automatic recording is given to the recording unit 104a. In addition, the CPU 118 gives an instruction to start automatic recording to the recording unit 104a at 20:00. Then, at 20:45, an instruction to stop automatic recording is given to the recording unit 104a. Further, the CPU 118 gives an automatic recording start instruction to the recording unit 104a at 21:00. Then, at 21:00, the CPU 118 gives an automatic recording stop instruction to the recording unit 104a. Thereby, each recommended program registered in the recommended program table is automatically recorded.

  Note that the recording unit 104 a is set to write an MPEG2 stream representing a recommended program to be automatically recorded in an automatic recording directory provided in the HD drive 121. The recording unit 104 a is set to write an MPEG2 stream representing a broadcast program to be manually recorded in a manual recording directory provided in the HD drive 121. That is, MPEG2 data representing the recommended program automatically recorded is stored in the automatic recording directory of the HD drive 121, and MPEG2 data representing the manually recorded broadcast program is stored in the manual recording directory of the HD drive 121. .

  Here, the manual recording refers to a recording mode in which a broadcast program broadcast on a channel selected by the user is recorded over a period specified by the user. In the present embodiment, broadcasting is performed on the channel selected as the channel selection target channel during the period from when the recording start button (REC button) on the remote control is pressed until the recording stop button (STOP button) on the remote control is pressed. Manual recording is realized by recording the broadcast program to be recorded. That is, in manual recording, the start of the recording period is specified by pressing the recording start button, and the end of the recording period is specified by pressing the recording stop button. In addition, a recording target channel is designated by pressing a channel selection button (numeric keypad or channel up / down button) on the remote controller, which is performed prior to pressing the recording start button.

(Recording function)
As described above, the television 1 has a recording function for recording a broadcast program received by the terrestrial digital broadcast tuner 102 and the satellite broadcast tuner 103. Hereinafter, the recording function of the television 1 will be described with reference to FIGS. 1 and 3. In the following, a recording function for recording a broadcast program received by the terrestrial digital broadcast tuner 102 will be described. However, a recording function for recording a broadcast program received by the satellite broadcast tuner 103 can be similarly realized.

  As shown in FIG. 1, the recording / playback unit 104 includes a recording unit 104a and a playback unit 104b. The recording unit 104a includes a manual recording buffer, an automatic recording buffer, and a writing processing unit (not shown), and the playback unit 104b includes a reading processing unit, a playback buffer, and a decoding unit (not shown). It is configured.

  The manual recording buffer is a buffer for storing an MPEG2 stream broadcast via a channel selected as a channel to be selected by the terrestrial digital broadcast tuner 102 among the MPEG2 streams supplied from the terrestrial digital broadcast tuner 102. . An MPEG2 stream representing a manually recorded broadcast program is stored in the manual recording buffer.

  The automatic recording buffer is a buffer for storing an MPEG2 stream broadcast through a channel selected by the terrestrial digital broadcast tuner 102 as a recording target channel among the MPEG2 streams supplied from the terrestrial digital broadcast tuner 102. An MPEG2 stream representing a recommended program to be automatically recorded is stored in this automatic recording buffer.

  The writing processing unit is means for writing the MPEG2 stream stored in the manual recording buffer and the MPEG2 stream stored in the automatic recording buffer to the HD drive 121.

  When a manual recording start instruction is given from the CPU 118, the write processing unit included in the recording unit 104a issues a write command for writing the MPEG2 stream stored in the manual recording buffer to the manual recording directory to the HD drive 121. At the same time, the MPEG2 stream stored in the manual recording buffer is transferred to the HD drive 121. The writing processing unit repeats such processing until a manual recording stop instruction is given from the CPU 118. Thereby, manual recording of a broadcast program is realized.

  Here, the timing at which the CPU 118 gives a manual recording start instruction is the time when a remote control signal indicating that the recording start button has been pressed is detected. On the other hand, the timing at which the CPU 118 gives a manual recording stop instruction is a point in time when a remote control signal indicating that the recording stop button has been pressed is detected. However, instead of providing a manual recording stop instruction when a remote control signal indicating that the recording stop button has been pressed is detected, a configuration is adopted in which a recording stop instruction is given at the end of the broadcast of a broadcast program to be manually recorded. May be. It should be noted that when the broadcast of a broadcast program to be manually recorded ends, it can be specified by referring to the broadcast program table described above.

  On the other hand, when an automatic recording start instruction is given from the CPU 118, the write processing unit included in the recording unit 104a sends a write command for writing the MPEG2 stream stored in the automatic recording buffer to the automatic recording directory on the HD drive 121. And the MPEG2 stream stored in the automatic recording buffer is transferred to the HD drive 121. The writing processing unit repeats such processing until an automatic recording stop instruction is given from the CPU 118. Thereby, automatic recording of a recommended program is realized.

  Here, the timing at which the CPU 118 gives an automatic recording start instruction is the start of broadcasting of a recommended program to be automatically recorded. On the other hand, the timing at which the CPU 118 gives an instruction to stop automatic recording is when broadcasting of a recommended program to be automatically recorded ends. It should be noted that the recommended program to be automatically recorded can be identified at the start and end of broadcast by referring to the recommended program table described above.

  When the CPU 118 gives a manual recording start instruction to the writing processing unit, the title of the broadcast program to be recorded (which can be specified based on the EPG data) and the recording start time are set as the program ID of the broadcast program. And recorded in the manually recorded program table. Further, when a manual recording stop instruction is given to the writing processing unit, the recording stop time is recorded in the manually recorded program table in association with the program ID of the broadcast program to be recorded. Similarly, when giving an automatic recording instruction to the writing processing unit, the CPU 118 automatically records the title of the broadcast program (recommended program) to be recorded and the recording start time in association with the program ID of the broadcast program. Record in the program table. Further, when an automatic recording stop instruction is given to the writing processing unit, the recording stop time is recorded in the automatic recording program table in association with the program ID of the broadcast program (recommended program) to be recorded. The manually recorded program table and the automatically recorded program table are stored in, for example, the RAM 117 and referred to by the CPU 118 when displaying a recorded program list to be described later.

  Incidentally, the recording start button may be pressed in a state where the same channel as the recording target channel is selected as the channel selection target channel. That is, during the automatic recording of a recommended program, a recording start instruction for instructing the recording start of the recommended program may be given.

  In such a case, the writing processing unit records the MPEG2 stream representing the recommended program in both the manual recording directory and the automatic recording directory. Such duplicate recording includes, for example, a process of writing the MPEG2 stream stored in the manual recording buffer to the manual recording directory of the HD drive 121 and the automatic recording of the MPEG2 stream stored in the automatic recording buffer of the HD drive 121. This can be realized by alternately repeating the process of writing to the directory for use.

  FIG. 3 is a timing chart showing an automatic recording period and a manual recording period when manual recording of a recommended program during automatic recording is instructed by the user. FIG. 3A shows a case where manual recording is stopped when the recording stop button is pressed, and FIG. 3B shows a case where manual recording is stopped when the recommended program broadcast ends t3. In any case, automatic recording is performed from the beginning (broadcast start time t0) to the end (broadcast end time t3) of the recommended program, while manual recording is in the middle of the recommended program (when the recording start button is pressed t1). Is done from. Hereinafter, such a recording mode of the recommended program is referred to as “double recording”.

  As described above, the following two cases are assumed as the case where the user instructs the manual recording of the recommended program during the automatic recording. The first case is a case where the recording start button is pressed without knowing that the recommended program being viewed is automatically recorded. In this case, there is a high possibility that the user wants to watch all of the recommended programs later. The second case is a case where the recording start button is pressed while knowing that the recommended program being viewed is automatically recorded. In this case, there is a high possibility that the user desires to watch a part of the recommended program (the part broadcast after the recording start button is pressed) later.

  If the double recording shown in FIG. 3 is performed, the user's needs can be met in both the first case and the second case. That is, by playing back the MPEG2 data stored in the automatic recording directory, in response to the user's need to view all of the recommended programs later, by playing back the MPEG2 data stored in the manual recording directory, It is possible to meet the user's needs to view a part of the recommended program later.

(Playback function)
The television 1 has a reproduction function for reproducing a broadcast program recorded in the HD drive 121 as described above (hereinafter also referred to as “recorded program”). Hereinafter, the playback function of the television 1 will be described with reference to FIGS.

  FIG. 4 is a diagram exemplifying a recorded program list displayed on the LCD 110 by the television 1 in order to allow the user to select a recorded program to be reproduced. As shown in FIGS. 4A and 4B, the recorded program list 40 is provided with a manual recording tab 41a and an automatic recording tab 41b.

  When the user selects the manual recording tab 41a, the TV 1 lists the titles of each recorded program (corresponding to MPEG2 data stored in the manual recording directory) in the recorded program list 40 together with the recording time. indicate. FIG. 4A shows a recorded program list 40 displayed at this time. It should be noted in the recorded program list 40 shown in FIG. 4A that only the manual recording was performed on the title of the recorded program that was also automatically recorded (“movie 1” in the example of FIG. 4A). It is displayed so that it can be distinguished from the titles of other recorded programs. Thereby, the user can easily recognize which recorded program is automatically recorded, that is, which recorded program can be reproduced from the beginning. The “recorded program with automatic recording” is nothing but a recommended program that has been double-recorded.

  In the example shown in FIG. 4A, a special icon (smile icon in the example of FIG. 4A) is attached to the title of a recorded program that has also been automatically recorded, so that this is only recorded manually. However, the present invention is not limited to this. That is, for example, by making the display mode (character color, background color, font, weight, etc.) of a recorded program that has also been automatically recorded special, this is the case of a recorded program that has only been manually recorded. You may employ | adopt the structure distinguished from a title.

  On the other hand, when the user selects the automatic recording tab 41b, the television 1 records the title of each automatically recorded program (corresponding to MPEG2 data stored in the automatic recording directory) in the recorded program list 40 together with the recording time. To list. FIG. 4B shows a recorded program list 40 displayed at this time. It should be noted in the recorded program list 40 shown in FIG. 4B that only the automatic recording was performed for the title of the recorded program that was also manually recorded (“movie 1” in the example of FIG. 4B). It is displayed so that it can be distinguished from the titles of other recorded programs. Thereby, the user can easily recognize which recorded program can be reproduced from the middle. The “recorded program with manual recording” is nothing but a recommended program that has been double-recorded.

  In the example shown in FIG. 4B, a special icon (smile icon in the example of FIG. 4B) is attached to the title of a recorded program that has also been manually recorded, so that only automatic recording is performed. However, the present invention is not limited to this. That is, for example, by making the display mode (character color, background color, font, weight, etc.) of the title of a recorded program for which manual recording has been performed special, You may employ | adopt the structure distinguished from a title.

  FIG. 5 is a diagram illustrating a dialog displayed on the LCD 110 by the television 1 when any one of the titles displayed in the recorded program list 40 is selected.

  When the user selects a title of a recommended program that has been double-recorded from the recorded program list 40 shown in FIG. 4A, the television 1 displays a dialog 50 shown in FIG. The dialog 50 includes a message indicating that the program is being recorded automatically and / or that the program can be reproduced from the beginning. The dialog 50 also includes a manual recording program button for instructing to reproduce the program from the middle using MPEG2 data stored in the manual recording directory, and MPEG2 stored in the automatic recording directory. There is provided an automatic recording program button for instructing to reproduce the program from the beginning using the data.

  On the other hand, when the user selects the title of the recommended program that has been double-recorded from the recorded program list 40 shown in FIG. 4B, the television 1 displays a dialog 50 shown in FIG. 5B. This dialog 50 includes a message indicating that manual recording of the program is being performed and / or that the program can be played back halfway (the portion recorded when the recording button is pressed). The dialog 50 also includes an automatic recording program button for instructing to reproduce the program from the beginning using MPEG2 data stored in the automatic recording directory, and MPEG2 stored in the manual recording directory. A manually recorded program button is provided for instructing to play the program from the middle using data.

  FIG. 6 is a flowchart showing a playback method in which the television 1 plays back a recorded program. Each step included in the flowchart shown in FIG. 6 will be described as follows.

  The television 1 displays the recorded program list 40 shown in FIG. 4, and allows the user to select a recorded program to be reproduced (step S1).

  Specifically, OSD data for displaying the recorded program list 40 shown in FIG. 4 is generated, and the generated OSD data is provided to the OSD generation unit 108. Then, the OSD generation unit 108 renders the recorded program list 40 from the OSD data acquired from the CPU 118 and displays the rendered recorded program list 40 on the LCD 110 as an OSD. The CPU 118 can generate OSD data for displaying the recorded program list 40 shown in FIG. 4A by referring to the above-described manually recorded program table. Further, OSD data for displaying the recorded program list 40 shown in FIG. 4B can be generated by referring to the above-described automatic recorded program table. In a state where the recorded program list 40 is displayed on the LCD 110, the CPU 118 waits for a user operation to select a title of the recorded program to be reproduced from the titles included in the recorded program list 40 displayed on the LCD 110.

  Next, the television 1 determines whether or not the recorded program corresponding to the title selected in step S1 is a recommended program that has been double-recorded (step S2).

  Specifically, when the title selected in step S1 is selected from the recorded program list 40 shown in FIG. 4A, the CPU 118 selects the title selected in step S1 (or It is checked whether or not the program ID associated with the title in the manually recorded program table is registered in the automatically recorded program table. If the title selected in step S1 is registered in the automatic video recording program table, it is determined that the program is a double-recorded recommended program, and if not, it is determined that the title is not a double-recorded recommended program. On the other hand, when the title selected in step S1 is selected from the recorded program list 40 shown in FIG. 4B, the CPU 118 selects the title selected in step S1 (or the automatically recorded program). It is checked whether or not the program ID associated with the title in the table is registered in the manually recorded program table. If the title selected in step S1 is registered in the manually recorded program table, it is determined that it is a recommended program that has been double-recorded, and if not, it is determined that it is not a recommended program that has been double-recorded.

  If the title selected in step S1 is not that of the recommended program that has been double-recorded (No in step S2), the television 1 plays back the recorded program corresponding to the title selected in step S1 (step S3). .

  Specifically, when the title selected in step S 1 is selected from the recorded program list 40 shown in FIG. 4A, the CPU 118 accumulates in the manual recording directory of the HD drive 121. The MPEG2 data representing the recorded program corresponding to the title selected in step S1 is identified from the MPEG2 data, and the identified MPEG2 data is notified to the playback unit 104b. On the other hand, when the title selected in step S1 is selected from the recorded program list 40 shown in FIG. 4B, the CPU 118 stores the MPEG2 data stored in the automatic recording directory of the HD drive 121. MPEG2 data representing the recorded program corresponding to the title selected in step S1 is identified, and the identified MPEG2 data is notified to the playback unit 104b. Then, the playback unit 104b reads the notified MPEG2 data from the HD drive 121, and decodes the video signal and the audio signal from the read MPEG2 data.

  In step S3, if the title selected in step S1 is an automatically recorded program, the recorded program corresponding to the selected title is based on the MPEG2 data stored in the automatic recording directory. If the title played back from the beginning (the part recorded at the start of the broadcast) and selected in step S1 is a manually recorded program, the selection is made based on the MPEG2 data stored in the manual recording directory. The recorded program corresponding to the recorded title is reproduced from the middle (the part recorded when the recording start button is pressed).

  When the title selected in step S1 is a recommended program that has been double-recorded (Yes in step S3), the television 1 displays the dialog 50 shown in FIG. The user selects whether to play back a recorded program (also referred to as “recorded program”) or a manually recorded one (hereinafter also referred to as “manually recorded program”) (step S4).

  Specifically, the CPU 118 generates OSD data for displaying the dialog 5 shown in FIG. 5, and provides the generated OSD data to the OSD generation unit 108. At this time, if the title selected in step S1 is selected from the recorded program list 40 shown in FIG. 4A, the dialog 50 shown in FIG. 5A is displayed. Generate OSD data. On the other hand, if the title selected in step S1 is selected from the recorded program list 40 shown in FIG. 4B, the OSD for displaying the dialog 50 shown in FIG. 5B. Generate data. Then, the OSD generation unit 108 renders the dialog 50 from the OSD data acquired from the CPU 118 and displays the rendered dialog 50 on the LCD 110 as an OSD. With the dialog 50 displayed on the LCD 110, the CPU 118 waits for a user operation to press the automatic recording program button or the manual recording program button in the dialog 50 displayed on the LCD 110.

  When the user selects the reproduction of the manually recorded program in step S4, the television 1 is halfway through the recorded program corresponding to the title selected in step S1 (the portion recorded when the recording start button is pressed). (Step S5).

  Specifically, the CPU 118 specifies MPEG2 data representing the recorded program corresponding to the title selected in step S1 from the MPEG2 data stored in the manual recording directory of the HD drive 121, and specifies the specified MPEG. The data is notified to the playback unit 104b. The playback unit 104b reads the notified MPEG2 data from the HD drive 121, and decodes the video signal and the audio signal from the read MPEG2 data.

  When the user selects reproduction of the automatically recorded program in step S4, the television 1 reproduces the recorded program corresponding to the title selected in step S1 from the beginning (the part recorded at the start of broadcasting) (step S4). S6).

  Specifically, the CPU 118 specifies MPEG2 data representing the recorded program corresponding to the title selected in step S1 from the MPEG2 data stored in the automatic recording directory of the HD drive 121, and specifies the specified MPEG. The data is notified to the playback unit 104b. The playback unit 104b reads the notified MPEG2 data from the HD drive 121, and decodes the video signal and the audio signal from the read MPEG2 data.

(Delete function)
When the television 1 detects a remote control signal indicating that a delete button for accepting an instruction to delete an automatic recording program or a manual recording program is pressed, the television 1 deletes at least one of the automatic recording program and the manual recording program.

  Here, an example of a deletion process when the delete button is pressed in a state where an automatically recorded program is selected from double-recorded programs will be described. First, when a remote control signal indicating that the delete button has been pressed is detected, the CPU 118 displays the OSD data of the delete selection screen for inquiring whether to delete the automatic recording program or whether to delete the automatic recording program and the manual recording program. The generated OSD data is provided to the OSD generation unit 108. Then, the OSD generation unit 108 renders the deletion selection screen from the OSD data acquired from the CPU 118, and displays the rendered deletion selection screen on the LCD 110 as an OSD.

  CPU 118 accepts a user's selection operation performed according to the deletion selection screen by a remote control signal. When the user selects deletion of the automatically recorded program, the CPU 118 specifies MPEG2 data representing the recorded program corresponding to the selected automatically recorded program from the MPEG2 data stored in the automatic recording directory of the HD drive 121. The HD drive 121 is notified to delete the specified MPEG data.

  When the user selects deletion of the automatically recorded program and the manually recorded program, the CPU 118 first represents a recorded program corresponding to the manually recorded program selected from the MPEG2 data stored in the automatic recording directory of the HD drive 121. Specify MPEG2 data. Next, the CPU 118 specifies MPEG2 data representing a recorded program corresponding to the manually recorded program that has been double-recorded simultaneously with the automatically recorded program, selected from the MPEG2 data stored in the manual recording directory. The CPU 118 notifies the HD drive 121 to delete the two specified MPEG data.

(Modification 1)
Although the configuration (double recording) in which automatic recording and manual recording are executed in parallel when the user instructs manual recording of a recommended program during automatic recording, the present invention is not limited to this. . That is, instead of a configuration in which automatic recording and manual recording are performed in parallel (double recording), a configuration in which automatic recording is temporarily stopped (relay recording) while manual recording is being performed may be employed. The latter configuration will be described below with reference to FIGS.

  FIG. 7 is a timing chart showing an automatic recording period and a manual recording period when manual recording of a recommended program during automatic recording is instructed by the user. FIG. 7A shows a case where manual recording is stopped when the recording stop button is pressed, and FIG. 7B shows a case where automatic recording is stopped when the recommended program broadcast ends t3. In any case, automatic recording is performed in the period from the broadcast start time t0 to the manual recording start time t1. When manual recording is stopped when the recording stop button is pressed as shown in FIG. 7A, automatic recording is also performed during the period from the manual recording stop time t2 to the broadcast end time t3.

  By adopting such a configuration, it is possible to eliminate wasted recording capacity due to the overlap between manual recording and automatic recording.

  FIG. 8 is a flowchart showing a method for reproducing an automatically recorded program (relay reproduction) suitable for adopting a configuration in which automatic recording is paused during manual recording. By adopting the automatic recording program playback method shown in FIG. 8 as step S6 in the flowchart shown in FIG. 6, the flowchart shown in FIG. 6 is suitable for the modification shown in FIG. Note that the recorded program list 40 displayed in step S1 and the dialog 50 displayed in step S4 may be those shown in FIGS.

  Each step included in the flowchart shown in FIG. 8 will be described as follows.

  The CPU 118 identifies MPEG2 data representing the recorded program to be reproduced from the MPEG2 data stored in the automatic recording directory of the HD drive 121, and notifies the reproduction unit 104b of the identified MPEG2 data. Then, the playback unit 104b reads the notified MPEG2 data from the HD drive 121, and decodes the video signal and the audio signal from the read MPEG2 data (step S61).

  When the playback unit 104b starts playback of the automatically recorded program, the CPU 118 monitors the playback time t of the automatically recorded program by the playback unit 104b (step S62). When the playback time t reaches the time difference T (see FIG. 8) between the broadcast start time t1 and the manual recording start time t2 (No in step S62), the CPU 118 stores the manual recording directory of the HD drive 121. MPEG2 data representing a recorded program to be reproduced is identified from the MPEG2 data, and the identified MPEG2 data is notified to the reproduction unit 104b. Then, the playback unit 104b reads the notified MPEG2 data from the HD drive 121, and decodes the video signal and the audio signal from the read MPEG2 data (step S63).

  Further, the CPU 118 moves the MPEG2 data corresponding to the manually recorded program to be relay-reproduced from the manual recording directory to the automatic recording directory when the automatic recorded program is relay-reproduced. It is good also as one recorded program which combined. Note that MPEG2 data corresponding to a manually recorded program to be relay-played may be copied to the automatic recording directory instead of being moved from the manual recording directory to the automatic recording directory.

  Further, when the television 1 detects a remote control signal indicating that the delete button has been pressed, the television 1 deletes at least one of the automatically recorded program and the manually recorded program.

  Here, a description will be given by taking as an example a deletion process when the delete button is pressed in a state in which an automatically recorded program is selected from relay recorded programs. First, when a remote control signal indicating that the delete button has been pressed is detected, the CPU 118 inquires whether to delete the automatic recording program or whether to delete the automatic recording program and the manual recording program. And the generated OSD data is provided to the OSD generation unit 108. Then, the OSD generation unit 108 renders the deletion selection screen from the OSD data acquired from the CPU 118, and displays the rendered deletion selection screen on the LCD 110 as an OSD.

  Hereinafter, since the same processing as the deletion processing of the double-recorded program is performed, description thereof is omitted.

(Modification 2)
When manual recording of a recommended program during automatic recording is instructed by the user, a configuration has been described in which MPEG2 data obtained by manual recording is recorded separately from MPEG2 data obtained by automatic recording. However, the present invention is not limited to this. Not. That is, instead of recording MPEG2 data obtained by manual recording, a time when a recording start instruction serving as a manual recording start trigger is given and / or a time when a recording stop instruction serving as a manual recording stop trigger is given Even if you adopt a configuration to record. The latter configuration will be described below with reference to FIGS.

  FIG. 9 is a timing chart showing an automatic recording period and a recording time when a user instructs to manually record a recommended program during automatic recording.

  FIG. 9A shows a case where the recording start instruction is given, that is, the recording start button is pressed t1, and the recording stop instruction is given, that is, the recording stop button is pressed t2. FIG. 9B shows a case where only t1 is recorded when the recording start button is pressed. The recording start button press time t1 and the recording stop button press time t2 may be recorded at an absolute time such as xx hour xx minute xx second, or may be recorded at a relative time based on the broadcast start time t0. May be. Further, the time t1 when the recording start button is pressed and the time t2 when the recording stop button is pressed may be recorded in the manually recorded program table in association with the program ID of the broadcast program to be recorded, for example.

  Even if MPEG2 data obtained by manual recording is not recorded, MPEG2 data obtained by manual recording can be obtained by recording t1 when recording start button is pressed and / or t2 when recording stop button is pressed as shown in FIG. As in the case of recording the recommended program, the recommended program can be reproduced from the middle (from the location recorded at the recording start time t1).

  FIG. 10 is a flowchart showing a method for reproducing a manually recorded program, which is preferable when the configuration in which t1 is recorded when the recording start button is pressed is adopted. As step S5 in the flowchart shown in FIG. 6, by adopting the method for reproducing the manually recorded program shown in FIG. 10, the flowchart shown in FIG. 6 is suitable for the modification shown in FIG. Note that the recorded program list 40 displayed in step S1 and the dialog 50 displayed in step S4 may be those shown in FIGS.

  Each step included in the flowchart shown in FIG. 10 will be described as follows.

  The CPU 118 reads t1 when the recording start button is pressed, which is associated with the program ID of the broadcast program to be reproduced, among the pressings of the recording start button registered in the manual recording program table (step S51). Here, when the recording start button is pressed, t1 [seconds] when the recording button is recorded, which is recorded at a relative time based on the broadcast start time of the broadcast program to be reproduced, is read.

  Next, the CPU 118 identifies MPEG2 data representing the broadcast program to be reproduced from the MPEG2 data stored in the automatic recording directory of the HD drive 121, and notifies the reproduction unit 104b of the identified MPEG2 data. At this time, the CPU 118 instructs the reproduction unit 104b to reproduce the broadcast program to be reproduced from the t1 second. Then, the playback unit 104b reads the notified MPEG2 data from the HD drive 121, and plays back the broadcast program to be played back from the t1 second based on the read MPEG2 data (step S52).

  Further, when the TV 1 detects a remote control signal indicating that the delete button has been pressed, the TV 1 deletes at least one of the automatically recorded program and the recorded program automatically recorded after the recording start button is pressed.

  Here, an example of a deletion process when the delete button is pressed while an automatically recorded program is selected will be described. When the CPU 118 detects a remote control signal indicating that the delete button has been pressed, the CPU 118 inquires whether to delete all the recorded programs or whether to delete a recorded program automatically recorded before the recording start button is pressed. OSD data is generated, and the generated OSD data is provided to the OSD generation unit 108. Then, the OSD generation unit 108 renders the deletion selection screen from the OSD data acquired from the CPU 118, and displays the rendered deletion selection screen on the LCD 110 as an OSD.

  Hereinafter, since the same processing as the deletion processing of the double-recorded program is performed, description thereof is omitted.
