Description

  The present invention relates to a content recording apparatus and a content recording method.

  In recent years, various digital broadcasting contents have spread and their copyright management has become an important issue. Digital broadcast content can be easily duplicated with almost no deterioration in the quality of video data compared to conventional analog broadcast content. Therefore, there are some digital broadcast contents to which a copy once control signal is added as a copyright management function. Content having this control signal is referred to as copy-once content. For copy-once content, after recording once, only a duplication method called “move” is permitted, and substantial copy (dubbing) cannot be performed. That is, when copying is performed on copy-once content recorded on the recording device, the recording source content is deleted from the recording device. Therefore, each family member cannot copy a program recorded at home and enjoy it in his / her room. In addition, the copy once content can be moved only to a DVD-R / RW, a DVD-RAM, or the like that supports CPRM (Content Protection for Recordable Media). Furthermore, when a digital broadcast content recorded with high image quality is compressed and converted to low image quality, the high-quality file at the recording source is erased and cannot be restored to high-quality content again. As described above, the copy-once content has many disadvantages for the user in terms of use and management.

In order to solve the above problems, several inventions including a copy once content management method have been disclosed in recent years. For example, Patent invention 1 is an invention that enables moving content while maintaining reusability of recorded high-quality content when high-quality content is compressed and converted into low-quality content by movement. However, because of legal restrictions, an invention for dubbing copy-once content with one recording device is not disclosed.

<< Embodiment 1 >>
<Embodiment 1: Overview> Embodiment 1 relates to a recording apparatus and a recording method. FIG. 1 is a diagram illustrating the concept of the present embodiment. As shown in this figure, the recording apparatus (0101) according to the present embodiment is configured to receive one digital broadcast content (0103) and a simulcast of the content by one recording command (0102) via a remote controller or the like from the user. The analog broadcast content (0104) is received, and the two contents are simultaneously recorded (0105).

  Embodiment 1 Configuration FIG. 2 is a functional block diagram of a recording apparatus according to this embodiment. As shown in this figure, the recording apparatus (0200) of this embodiment includes a digital broadcast receiving unit (0201), an analog broadcast receiving unit (0202), a recording command receiving unit (0203), a recording unit (0204), and a control unit. (0205). Hereinafter, the configuration and function of each unit will be described.

  The “digital broadcast receiving unit” (0201) is a unit that receives and demodulates a digital broadcast signal via a digital broadcast antenna. For example, a digital broadcast receiving tuner and a digital broadcast signal demodulating circuit are applicable. As used herein, “digital broadcasting” means terrestrial digital broadcasting (including 1-segment broadcasting), digital satellite broadcasting (including BS digital, CS digital, CS110 °), and cable digital broadcasting. The content broadcast by the broadcast is “digital broadcast content”. In the present application, the digital broadcast content is not limited to copy-once content unless otherwise specified, and includes digital broadcast content to which a copy control signal other than the copy-once control signal is added, and digital broadcast content to which no copy control signal is added. Shall be included.

  The “analog broadcast receiving unit” (0202) is a unit that receives an analog broadcast signal via an analog broadcast antenna. For example, an analog broadcast receiving tuner is applicable. As used herein, “analog broadcasting” means terrestrial analog broadcasting, analog satellite broadcasting (including BS analog and CS analog), and cable analog broadcasting. The content broadcast in the broadcast is “analog broadcast content”.

  The “recording command reception unit” (0203) is configured to receive a recording command. The “recording command” is a command for recording a specific content in a recording unit described later. The recording command specifies, for example, one or more of a broadcasting system (for analog broadcasting or digital broadcasting), channel or broadcasting station name, recording date, recording start time, and recording end time (recording time frame). The content to be recorded can be specified as a single by the information. One recording command is a command that can specify the same analog broadcast content and digital broadcast content at a time, as will be described later.

  The recording command may be created based on the electronic program guide. FIG. 3 shows a specific example of creating a recording command based on the electronic program guide. The upper table in FIG. 3 shows an electronic program table (0301) for digital broadcasting. After selecting “News 11” (0302) from this table and further selecting a recording reservation button (0303), “Channel = 3”, “Broadcasting station name = TV sunset”, “Broadcasting date” for digital broadcasting = August 1, 2006 "," Broadcast start time = 23: 00 ", and" Broadcast end time = 23: 50 "are recorded in the recording device (0304). This recording information becomes one recording command. In this example, the broadcast date corresponds to the recording date, the broadcast start time corresponds to the recording start time, and the broadcast end time corresponds to the recording end time. The recording command reception unit has a function as an interface for transmitting the received recording command to the recording unit described later. The recording command receiving unit may be configured by an infrared light receiver sensor, an ultrasonic signal sensor, a Bluetooth (registered trademark) signal sensor, or the like, or may be configured to receive a recording command by wire. When the recording command is directly received by the recording apparatus main body, a recording operation button is provided.

  The “recording unit” (0204) has a recording medium and its drive. For example, recording media such as a hard disk (HD), an HD-DVD disk, a DVD ± RW disk, a DVD-RAM disk, a Blu-ray disk (registered trademark), and a drive unit thereof may be used. In addition, a NAND flash memory having a large capacity is also applicable. When the recording medium is composed of a removable disk, the disk does not always have to be inserted into the recording device. The recording unit can record both digital broadcast content and analog broadcast content. In addition, the recording unit can record digital broadcast content and analog broadcast content simultaneously due to the configuration requirements. As a configuration example for such simultaneous recording, there is a case where the recording unit includes a plurality of recording media and each drive unit. In this case, the digital broadcast content and the analog broadcast content may be recorded independently on each recording medium. Also, the received digital broadcast content and analog broadcast content may be segmented and recorded on one recording medium alternately. In the second and later embodiments described later, at least one recording medium included in the recording unit and its drive unit need to be capable of recording a copy-once content.

  The “control unit” (0205) includes one digital broadcast content received by the two receiving units according to one recording command received by the recording command receiving unit, an analog broadcast content that is a simulcast of the content, In order to record simultaneously, the recording unit and the receiving unit can be controlled. The “one recording command” is a command necessary for recording a specific content, and is a command received by the recording command receiving unit. The one recording command is for digital broadcast content or analog broadcast content, but the control unit can specify both broadcast contents of the same content at one time regardless of the recording command for any broadcasting system. Yes. This will be described later. “Analog broadcast content that is a simulcast of the content” means an analog of the same content broadcast from one broadcast station at the same time as one digital broadcast content, as described in “Means for Solving the Problems” above. Broadcast content. “Simultaneous recording” refers to simultaneous recording of one digital broadcast content and analog broadcast content that is the simulcast. However, the recording of both contents does not necessarily have to be completely synchronized. For example, the case where the recording unit segments each content and writes it alternately to the recording medium as in the case where both contents are recorded on the one recording medium is also included.

  The control unit can control both the digital broadcast receiving unit (0201) and the analog broadcast receiving unit (0202) to receive specific content of the same content by one recording command. Usually, a recording command is accepted for each broadcasting system, such as a recording command for digital broadcasting and a recording command for analog broadcasting. For example, when a digital broadcast recording command is accepted as a single recording command, recording is performed only on the digital broadcast content. However, the control unit of the present embodiment can execute the same recording command for both broadcast contents, regardless of which broadcast format is the received one recording command. For example, there is a case where the control unit creates a recording command for simulcast with respect to the broadcasting method of one recording command received by the recording command receiving unit.

  FIG. 4 illustrates an example of creating a recording instruction for simulcast. FIG. 4 shows a case where the recording command receiving unit (0402) receives a digital broadcast recording command (0401) as one recording command. The digital broadcast recording command (0401) received by the recording command receiving unit (0402) is sent to the control unit (0403). The control unit acquires information (0404) such as a recording start time, a recording end time (recording time frame), and a broadcasting station name from the digital broadcast recording command. Such information can be extracted from, for example, an electronic program guide for digital broadcasting as will be described later. Subsequently, the information is collated with the information in the electronic program guide (0405) of analog broadcasting which is the other broadcasting system. An analog broadcast recording command (0406) is created from the information of the analog broadcast content electronic program guide that matches the collation. The control unit can control the digital broadcast receiving unit (0407) and the analog broadcast receiving unit (0408) by using these two recording commands (0401, 0406). Further, the control unit can control the recording unit (0409) to simultaneously record the digital broadcast content received by the two receiving units and the analog broadcast content that is the simulcast.

  A specific example of a method for extracting and collating information for creating a recording command for simulcast in the control unit will be described in detail with reference to FIG. This figure is a conceptual diagram showing information of each broadcast electronic program guide. In the digital broadcast electronic program guide (a), each content is classified into information categories such as “content title”, “channel”, “broadcast station name”, “broadcast date”, “broadcast start time”, “broadcast end time”. It is configured. The received digital broadcast recording command (0501: inside broken line) is “content title = news 11”, “channel = 3”, “broadcasting station name = TV sunset”, “broadcast date = August 1, 2006”. ”,“ Broadcast start time = 23: 00 ”, and“ broadcast end time = 23: 50 ”. For example, the control unit extracts information categories of “content title”, “broadcast station name”, “broadcast date”, “broadcast start time”, and “broadcast end time” from the information of the recording command for digital broadcast. Subsequently, the information in the extracted information category is collated with the information in the corresponding information category in the analog broadcast electronic program guide (b). The analog broadcast content that matches all the information in the extracted information category corresponds to the simulcast content. As the analog broadcast recording command (0502) for the analog broadcast content determined as the simulcast from the analog broadcast electronic program guide, the control unit sets “content title = news 11”, “channel = 8”, “broadcast station”. = TV sunset, “Broadcast date = August 1, 2006”, “Broadcast start time = 23: 00”, “Broadcast end time = 23: 50” are newly created. The analog broadcast recording command is an analog broadcast recording command that is a simultaneous broadcast of the received one digital broadcast recording command (0501).

  The most characteristic point of this embodiment is that digital broadcast content and analog broadcast content that is a simulcast can be recorded simultaneously with one recording command as described above. Some conventional recording apparatuses have a function capable of recording digital broadcast content and analog broadcast content, respectively. Therefore, if such a model is used, it is not impossible to record one digital broadcast content and analog broadcast content that is the simulcast. However, since the conventional recording apparatus is only intended to widen the selectivity of the recording method for the user, the recording command for each broadcasting method is independent. Therefore, in order to record each broadcast content, a recording command for each broadcast method must be separately performed, and the operation is complicated. In the recording apparatus of the present embodiment, the contents of both broadcasting systems can be received and recorded simultaneously by any broadcasting recording command by the function of the control unit. Alternatively, in the case of a digital broadcast recording command, it is possible to receive both broadcast contents and perform simultaneous recording, and in the case of an analog broadcast recording command, only analog broadcast content can be received and recorded. Note that the function of simultaneously recording the digital broadcast content and the analog broadcast content that is the simulcast with a single recording command may be releasable according to user preference. In that case, only the content in accordance with the broadcast method of the recording command is recorded as in the conventional recording apparatus.

  <Embodiment 1: Hardware Configuration> FIG. 6 shows a hardware configuration in the first embodiment. Each unit, which is a component of the recording apparatus of the present embodiment, is configured by both and / or hardware. 6 includes a CPU (0601), a volatile memory (0602), a nonvolatile memory (0603), a recording nonvolatile memory (0604), a digital tuner (0605), and an analog tuner ( 0606), a demodulating circuit (0607), a decoding circuit (0608), an interface (0609), a system bus (0610) connecting them, peripheral devices (not shown), and the like, and the hardware There is software that can run on the above. Note that the recording nonvolatile memory corresponds to an HDD, a NAND flash memory having a large capacity, or the like. As software, the functions of each unit are realized by sequentially executing a program developed on the memory, and processing, storing, and outputting data on the memory and data input through the interface.

  The hardware configuration will be specifically described with an example. The digital broadcast receiving unit (0201) shown in FIG. 2 corresponds to a digital tuner (0605), a demodulation circuit (0607), a decoding circuit (0608), and the like. The digital broadcast receiver first selects a received digital broadcast signal with a digital tuner. Next, the demodulation circuit demodulates the selected broadcast signal and converts it into a digital signal. Subsequently, the decoding circuit decodes the digital signal. The decrypted digital broadcast content is stored in a recording non-volatile memory. The analog broadcast receiver (0202) corresponds to an analog tuner (0606). The analog broadcast receiver selects the received analog broadcast signal with an analog tuner. The obtained analog signal is stored in the recording non-volatile memory as it is or after being subjected to predetermined processing. The recording command receiving unit (0203) corresponds to the interface (0606). Although not shown, the recording command receiving unit may have a sensor in addition to this. A recording command, which is information input via the interface, is transmitted to the control unit and processed. The control unit (0205) corresponds to a CPU (0601), a volatile memory (0602), a nonvolatile memory (0603), and the like. The CPU develops various programs stored in the nonvolatile memory in the volatile memory, and performs processing according to the programs. For example, the CPU stores the recording command information in a volatile memory, and executes processing of the information according to a simultaneous broadcast recording command creation program. The received recording command information and the created recording command information are processed according to the control program. The recording unit (0204) corresponds to a CPU (0601), a volatile memory (0602), a large-capacity nonvolatile memory (0603), and the like. The CPU of the recording unit expands the recording program stored in the non-volatile memory in the work area of the volatile memory, holds the received broadcast content in the non-volatile memory with a large capacity, or is inserted into the optical disc drive Can be recorded on an optical disk. FIG. 6 merely shows an example of the hardware configuration of the recording / reproducing apparatus, and the present invention is not limited to these configurations.

  <Embodiment 1: Processing Flow> A recording method according to the present embodiment will be described with reference to FIG.

  FIG. 7A is a flowchart of the recording method of the present embodiment. First, the recording apparatus receives one recording command (S0701 recording command receiving step). Next, one digital broadcast content from the digital broadcast receiving unit and the analog broadcast receiving unit, and an analog broadcast content that is a simulcast of the content by one recording command received in the recording command receiving step (S0701), respectively Receive (S0702 content reception step). Finally, both contents received in the content receiving step (S0702) are recorded simultaneously (S0703 simultaneous recording step). The recording method according to the present embodiment can be realized by the above processing flow.

  FIG. 7B is a flowchart for explaining in more detail the processing flow of the content receiving step (S0702) of FIG. 7A. First, the recording apparatus receives one recording command (S0701 recording command receiving step). Next, necessary recording information is extracted from the one recording command received in the receiving step (S0701) in order to create a recording command for simulcast (S0702-1 recording information extracting step). The broadcasting system of the simultaneous broadcasting of the one recording command received in the recording command receiving step (S0701) is determined, and the electronic program guide for the broadcasting is acquired (S0702-2 broadcasting system determining step). The recording information extracted in the recording information extraction step (S0702-1) is collated with the information of the electronic program guide of the simulcast acquired in the broadcasting system determination step (S0702-2) (S0702-3 recording information collation step). A simulcast recording command is created based on the simulcast electronic program guide information matched in the recorded information collation step (S0702-3) (S0702-4 simulcast recording command creation step). According to the two recording commands of the recording command received in the recording command receiving step (S0701) and the simultaneous broadcasting recording command created in the simultaneous broadcasting recording command creating step (S0702-4), the digital broadcasting content and the analog broadcasting content are recorded. Two contents are received from each receiving unit. (S0702-5 both contents receiving step). Finally, both contents received in the both contents receiving step (S0702-5) are recorded simultaneously. The recording method according to the present embodiment can be realized by the above processing flow. Note that the order of processing of the recording information extraction step (S0702-1) and the simulcast system determination step (S0702-2) is not particularly limited. Therefore, either may be the first or may be processed simultaneously.

  <Embodiment 1: Effect> According to the recording apparatus and the recording method of the present embodiment, digital broadcast content and analog broadcast content that is a simulcast of the content can be recorded simultaneously by one recording command. Thereby, even when both contents are recorded, there is no need to separately perform a recording operation for each broadcast content, which is convenient.

<< Embodiment 2 >>
<Embodiment 2: Overview> Embodiment 2 relates to a recording apparatus and a recording method. The recording apparatus and the recording method according to the present embodiment are based on the recording apparatus and the recording method of the first embodiment. FIG. 8 is a diagram illustrating a concept in which the recording apparatus according to the present embodiment performs recording processing for two contents having the same content specified by the recording command. The recording apparatus (0800) according to the present embodiment searches (0804) whether the copy control signal is added to the digital broadcast content (0801) among the received two contents (0801 and 0802). When a copy control signal is added, the signal is read (0805), and two contents (0801) received only when a copy-once control signal (0803) “Copying only one generation is possible” is added (0801). , 0802).

  <Embodiment 2: Configuration> FIG. 9 is a functional block diagram of a recording apparatus according to the present embodiment. As shown in this figure, the recording apparatus (0900) of the present embodiment is based on the configuration of the recording apparatus of the first embodiment. That is, a digital broadcast receiving unit (0901), an analog broadcast receiving unit (0902), a recording command receiving unit (0903), a recording unit (0904), and a control unit (0905) are included. Since the description regarding these structural requirements is the same as that of the first embodiment, a description thereof will be omitted. A characteristic configuration in the configuration of the present embodiment is that the control unit (0905) further includes a determination unit (0906) and an addition time control unit (0907). Hereinafter, the configuration, function, and the like of the determination unit (0906) and the addition time control unit (0907) will be described.

  The “determination means” (0906) is configured to determine whether the digital broadcast content of the content specified by the recording command is the content to which the copy-once control signal is added. Currently, CGMS-A (Copy Generation Management System-Analog) is adopted as a copy-once system in Japanese terrestrial digital broadcasting and digital satellite broadcasting. CGMS-A is a copy guard system in which a duplication control signal is embedded in a blanking area of a digital signal to enable duplication generation management. The duplication control signal generally has information such as “copying allowed”, “copying possible for one generation”, “copying not possible”, and the like. Among these, the duplication control signal having the information that “only one generation can be copied” corresponds to the “copy once control signal” in the present application. In CGMS-A, the broadcast station side adds (or superimposes) a duplication control signal to the digital broadcast and outputs it. Then, the recording device side that has received the information reads the information of the duplication control signal and determines whether or not to permit the recording operation. Therefore, the judging means first searches for whether the copy control signal is embedded in the blanking area of the received digital broadcast content. Next, when a duplication control signal is embedded, it is configured to read the signal and determine whether or not it is a determination result that “one generation can be copied”. The information of the determination result is transmitted to the next addition time determination means. Note that “content specified by a recording command” refers to two broadcast contents of the same content that have been designated for recording by one recording command.

  “Additional control means” (0907) is a digital broadcast content received only when the judgment result received from the judgment means is a judgment result that a copy-once control signal is added, and a simulcast of the content. The analog broadcast content is controlled to be recorded simultaneously. If the determination result is a determination result other than the determination result that the copy-once control signal is added, it is possible to record digital broadcast content and / or analog broadcast content that is a simulcast of the content. To. Which content is recorded may be selected according to the user's preference. When one content is selected by default, digital broadcast content is desirable. If there is no copy restriction, digital broadcasting content can be dubbed and edited without substantially degrading the quality of the video data. However, the content to which the copy control signal is added as a copy control signal is not limited to the above. This is because the content to which the information is added cannot be copied in the first place.

  <Second Embodiment: Hardware Configuration> The hardware configuration in the second embodiment is the same as the basic hardware configuration of the first embodiment shown in FIG. Therefore, the description of the same configuration as that of the first embodiment is omitted. Further, the specific hardware configurations of the determining means (0906) and the adding time control means (0907), which are characteristic features of the present embodiment, are the CPU (0601) and the volatile memory (0602) in FIG. ), A non-volatile memory (0603), and the like. In the judging means (0906), the CPU develops the copy control signal search processing program stored in the nonvolatile memory in the work area of the volatile memory, and processes the received digital broadcast content according to the program. That is, the CPU executes a search for a copy control signal with respect to the received digital broadcast content. If the result is “signal present”, the CPU subsequently executes information reading processing for the signal. The signal of the read information is transmitted to the addition time control means (0907). In the addition control means (0907), the CPU expands the copy execution program stored in the nonvolatile memory in the work area of the volatile memory, and executes processing according to the information of the copy control signal according to the program. When the signal information is information that “only one generation can be copied”, that is, when processing is performed that a copy-once control signal is added, the analog of simulcast that simultaneously received the digital broadcast content It is executed so as to record in the recording non-volatile memory of the recording unit together with the broadcast content.

  <Embodiment 2: Processing Flow> An example of a recording method according to the present embodiment will be described with reference to FIG. FIG. 10 is a flowchart of the recording method of the present embodiment. First, a recording command is received (S1001 recording command receiving step). Next, the digital broadcast receiving unit and the analog broadcast receiving unit receive the one digital broadcast content and the analog broadcast content that is a simulcast of the content by one recording command received in the recording command receiving step. (S1002 content reception step). The steps so far are the same as those in the first embodiment. In the present embodiment, subsequently, it is determined whether the digital broadcast portion of the content received in the content reception step and specified by the recording command is the content to which the replication control signal is added (S1003 replication control signal addition determination step). Here, when it is a determination result that the copy control signal is not added (No in S1003), normal recording is performed (S1006). In this case, what content is to be recorded may be selected according to the user's preference. If the content is a content to which a copy control signal is added (S1003 Yes), the information of the copy control signal is read to determine whether the information is a copy-once control signal (S1004 copy-once control signal added). Judgment step). Subsequently, if the determination result is a determination result that is not a copy-once control signal (No in S1004), normal recording is performed (S1006). Also in this case, as described above, which content is to be recorded can be selected according to the user's preference. However, this is not the case when the copy control signal is a non-copyable control signal. If the content is a content to which a copy-once control signal is added (S1004 Yes), both contents received in the content receiving step are recorded simultaneously (S1005 simultaneous recording step). The recording method according to the present embodiment can be realized by the above processing flow.

  <Embodiment 2: Effect> According to the recording apparatus and the recording method of the present embodiment, simultaneous recording can be performed even for digital broadcast content without copy restrictions, and the capacity of a recording medium more than necessary for that purpose can be achieved. Uselessness can be eliminated.

<< Embodiment 3 >>
<Embodiment 3: Overview> Embodiment 3 relates to a recording apparatus and a recording method. The recording apparatus and the recording method according to the present embodiment are based on the recording apparatus and the recording method of the first or second embodiment. FIG. 11 is a diagram showing the concept of the present embodiment, and shows one monitor screen of a television. In the case of normal recording processing, the recording apparatus of the present embodiment displays and manages one recorded content (1104) with one display mark (1105: thumbnail in this figure) on the monitor. However, in the case of two contents (1102, 1103) recorded at the same time, even if there are two contents, they are displayed with one display mark (1101) and managed.

  <Embodiment 3: Configuration> FIG. 12 is a functional block diagram of a recording apparatus according to the present embodiment. The recording apparatus (1200) of the present embodiment shown in this figure is based on the configuration of the recording apparatus of the second embodiment. That is, it is composed of a digital broadcast receiving unit (1201), an analog broadcast receiving unit (1202), a recording command receiving unit (1203), a recording unit (1204), and a control unit (1205). And an addition time control means (1207). Since the description regarding these structural requirements is the same as in the first and second embodiments, a description thereof will be omitted. A characteristic configuration in the configuration of the present embodiment is that the recording device (1200) further includes a content operation input GUI unit (1208) and a management unit (1209). The configuration, functions, and the like of the content operation input GUI unit (1208) and the management unit (1209) will be described below.

  The “content operation input GUI unit” (1208) is configured to realize a function as a normal GUI with respect to a recorded content file. Even in the case of the content recorded at the same time as described above, it has a function of displaying two content files with one display mark. Here, “GUI” (Graphical User Interface) uses graphics for displaying information to the user, and most operations are performed by command input using an input pointing device such as a mouse, keyboard, remote controller, or touch panel based on the graphics. It is a user interface that enables The “display mark” is a visual medium as a symbol on the GUI in order to display the presence of the content file on a monitor or the like. For example, icons, thumbnails, frames, character symbols, and the like can be given. The user can input an operation to the content file by selecting the display mark. Here, “select” means to bring the content file into an active state where operation input is possible. The “operation” here is a work command to be performed on the content file. For example, playback, copy, move, edit, delete, drag drop, file name change, history display, and the like can be mentioned. Furthermore, “operation input” means that a user inputs a desired operation via a display mark.

  Normally, one symbol such as an icon is assigned to one content file. However, in the present embodiment, the same symbol is assigned to the simultaneously recorded digital broadcast content file and the analog broadcast content file that is the simulcast. A mechanism in which the content operation input GUI unit assigns one display mark to two content files recorded simultaneously will be described below with an example. First, the content operation input GUI unit determines whether a recorded content file is related to another content file. As a result of the determination, if there is no relation, the content operation input GUI unit performs a process of assigning one display mark to the content file. Two content files recorded simultaneously are associated with each other. Therefore, as a result of the determination, if there is another associated content file, the content operation input GUI unit performs processing so as to assign the same display mark to the other associated content file. You just have to do it. At the same time, predetermined processing is performed on the two associated content files for various operation inputs to the one display mark. As described above, two content files can be displayed as one display mark on the monitor. Therefore, if one operation input is performed on the displayed one display mark, the operation can be executed on both content files.

  The “management unit” (1209) is configured to manage the content recorded in the recording unit in accordance with the operation received by the content operation input GUI unit. The “operation accepted by the content operation input GUI unit” is a work command input from the display mark by the content operation input GUI unit. “Management” means recording, holding, reproduction, deletion, and other processing. The management unit has a function of executing and processing the digital broadcast content file related to the display mark that has accepted one operation and the analog broadcast content file that is the simulcast. For example, when a display mark file name changing operation is performed, processing is performed to change both of the two content files recorded simultaneously. Other specific examples of the processing will be described in detail in Embodiments 4 to 7.

  <Third Embodiment: Hardware Configuration> The hardware configuration of the third embodiment is the same as the hardware configuration of the first embodiment shown in FIG. Therefore, the description of the same configuration as that of the first embodiment is omitted. In addition, regarding the specific hardware configuration of the content operation input GUI unit (1208) and the management unit (1209), which are characteristic configuration features of the present embodiment, the content operation input GUI unit (1208) The CPU (0601), the volatile memory (0602), the nonvolatile memory (0603), the interface (0605) and the like in FIG. 6 and the management unit (1209) are the CPU (0601) in FIG. 0602), nonvolatile memory (0603), and the like. The CPU of the content operation input GUI unit expands the GUI program stored in the non-volatile memory in the work area of the volatile memory and applies the program to two content files recorded in the non-volatile memory by simultaneous recording. The process according to the control information is performed. In addition, the CPU expands the operation program stored in the nonvolatile memory in the work area of the volatile memory, and processes the operation information input from the interface according to the program or the like. The CPU of the management unit receives the processed operation information, expands the operation execution program stored in the nonvolatile memory based on the information to the work area of the volatile memory, and responds to the control information of the program. Execute the process. As described above, the recording apparatus of the present embodiment can be realized.

  <Embodiment 3: Effect> According to the recording apparatus and the recording method of the present embodiment, the digital broadcast content recorded simultaneously and the analog broadcast content that is a simulcast of the content can be displayed with one display mark. . This makes it easy to manage the content because the user can treat both contents as if they were one piece of data.

<< Embodiment 4 >>
<Embodiment 4: Overview> Embodiment 4 relates to a recording apparatus and a recording method. The recording apparatus and the recording method according to the present embodiment are based on the recording apparatus and the recording method of the third embodiment. FIG. 13 is a diagram showing the concept of the present embodiment. In this figure, a monitor screen of a television to which the recording apparatus of this embodiment is connected is shown. In FIG. 13, two contents recorded simultaneously are displayed with one display mark (1301). When the recording apparatus according to the present embodiment selects the one display mark (indicated by a thick black frame) and inputs a copy operation of the content corresponding to the display mark from the screen button (1302), the digital broadcast content ( 1303) and analog broadcast content (1304), copy processing (1305) is executed only for analog broadcast content. According to the present embodiment, even if the digital broadcast content is copy-once content, it is retained (1306) in the recording apparatus as it is by the copy process and is not deleted, so that pseudo-dubbing of the copy-once content can be achieved.

  <Embodiment 4: Configuration> FIG. 14 is a functional block diagram of a recording apparatus according to the present embodiment. The recording apparatus (1400) according to the present embodiment shown in this figure is based on the configuration of the recording apparatus of the third embodiment. That is, a digital broadcast receiving unit (1401), an analog broadcast receiving unit (1402), a recording command receiving unit (1403), a recording unit (1404), a control unit (1405), a content operation input GUI unit (1408), a management unit (1409), and the control unit further includes determination means (1406) and addition time control means (1407). Since the description regarding these structural requirements is the same as in the first to third embodiments, a description thereof will be omitted. A characteristic configuration of the configuration of the present embodiment is that the management unit (1409) further includes a content copy unit (1410). Hereinafter, the configuration and function of the content copy unit (1410) will be described.

  When the content operation input GUI unit receives a copy operation input using a display mark, the “content copy unit” (1410) stores the content file held in the recording unit as a recording medium. It is configured to have a function as a dubbing means for performing copy processing. In addition, the content copy means, when the content operation input GUI unit receives an input of a copy operation for two simultaneously recorded content files displayed with one display mark, Select only the broadcast content file and execute the copy process. At this time, the content copy means does not perform a copy operation on the digital broadcast content. As described above, only one generation of copy-once content is permitted to be copied, but the original content that was in the transfer source at that time is deleted. That is, since the copy operation for the copy-once content is a move operation, the content file cannot be left in the transfer source recording apparatus. However, according to the present embodiment, even if the digital broadcast content is copy-once content, the original digital broadcast content file is retained without being lost from the recording unit. The content copied in this embodiment is analog broadcast content, not digital broadcast content. However, since it is a simulcast, its content is the same as the digital broadcast content. In addition, there is no restriction such as copy once with respect to the analog broadcast content, and it can be freely copied within the scope of the copyright law. Thus, according to the present embodiment, it is possible to pseudo-copy digital broadcast content while ensuring copyright protection. However, since the analog broadcast content has SD image quality, in this embodiment, when the copy once content has HD image quality, it cannot be copied as HD image quality. However, considering that DVD-R / RW, DVD-RAM, and the like that are currently available can only be recorded as SD image quality even if they are CPRM compatible, it is a big problem that they cannot be copied as HD image quality. Don't be. Rather, in consideration of the convenience of the user, there is a great effect that the content can be easily copied while keeping the HD quality content safely.

  The content copy means has a nonvolatile recording media drive as a component. Specific examples of the recording media drive include a device capable of copying content to an optical disk medium such as an HDD, an HD-DVD drive, a DVD ± RW drive, a DVD-RAM drive, a Blu-ray drive, or a magneto-optical disk such as an MO drive. In addition to devices that can copy content, devices that can be copied to an external recording medium by wire or wireless are also included. For example, other recording / playback devices connected by D terminal, HDMI terminal, DVI terminal, external HDD connected by USB, semiconductor memory, infrared communication, Bluetooth communication function, etc. This is an example. When the recording medium is composed of a removable disk, the disk is inserted at least during the copy process.

  <Fourth Embodiment: Hardware Configuration> The hardware configuration in the fourth embodiment is the same as the basic hardware configuration of the first embodiment shown in FIG. Therefore, the description of the same configuration as that of the first embodiment is omitted. Further, the specific hardware configuration of the content copy means, which is a characteristic feature of the present embodiment, corresponds to the CPU (0601), the volatile memory (0602), the nonvolatile memory (0603), etc. in FIG. To do. In the content copy means, the CPU (0601) receives a copy operation command signal from the content operation input GUI unit, and expands the content copy program stored in the nonvolatile memory in the work area of the volatile memory. In accordance with the copy operation command signal and the program, the CPU calls the target content file designated for copying from the recording non-volatile memory of the recording unit, and executes the duplication processing. At this time, when the CPU receives a signal that the content file designated for copying is related to the digital broadcast content file and the analog broadcast content file, the analog broadcast content is recorded from the recording non-volatile memory of the recording unit. Call file only and execute replication. As described above, the recording apparatus of the present embodiment can be realized.

  <Fourth Embodiment: Process Flow> An example of a recording method according to the present embodiment will be described with reference to FIG. FIG. 15 shows a flowchart of the recording method of the present embodiment. First, the recording apparatus receives an input of a copy operation via a display mark (S1501 copy operation input reception step). Next, it is determined whether the one display mark that has received the input of the copy operation is a display mark having two content files recorded simultaneously (S1502 display mark determination step). Finally, if the determination result in the display mark determination step (S1502) is a determination result that the display mark is for displaying two contents, copy processing is executed only for the analog broadcast content (S1503 analog broadcast content). Copy step). The recording method of the present embodiment can be achieved by the above processing flow.

  <Embodiment 4: Effect> According to the recording apparatus and the recording method of the present embodiment, by performing copy processing only on the analog broadcast content by a copy operation, simultaneous broadcasting of analog broadcast content recorded simultaneously can be performed. Certain digital broadcast contents can be left without being deleted. This enables pseudo dubbing of digital broadcast content. Further, since the copy process is performed on the analog broadcast content, a recording medium other than CPRM can be used.

<< Embodiment 5 >>
<Embodiment 5: Overview> The recording apparatus and the recording method according to the present embodiment are based on the recording apparatus and the recording method of Embodiment 3 or 4, and edit the content specified by using one display mark. When an operation input is accepted, the same editing process is executed for both of the two contents recorded simultaneously.

  <Embodiment 5: Configuration> FIG. 16 is a functional block diagram of a recording apparatus according to the present embodiment. The recording apparatus (1600) according to the present embodiment shown in this figure is based on the configuration of the recording apparatus of the third embodiment. That is, a digital broadcast receiving unit (1601), an analog broadcast receiving unit (1602), a recording command receiving unit (1603), a recording unit (1604), a control unit (1605), a content operation input GUI unit (1608), a management unit (1609), and the control unit further includes determination means (1606) and addition time control means (1609). Since the description regarding these structural requirements is the same as in the first to third embodiments, a description thereof will be omitted. A characteristic configuration in the configuration of the present embodiment is that the management unit (1609) further includes content editing means (1610). Hereinafter, the configuration and function of the content editing means (1610) will be described.

  The “content editing unit” (1610) edits the content file held in the recording unit when the content operation input GUI unit receives an input of an editing operation using a display mark. It is configured to have a function as an editing means. In addition, when the input of editing operation for the content specified by using one display mark is accepted in the content operation input GUI unit, the same editing processing is performed for both of the simultaneously recorded two contents. Is configured to run. “Content specified using one display mark” refers to a content file designated by selecting a display mark. The identified content file becomes active with respect to the editing operation from the state held in the recording unit. The content editing means can perform the input editing operation in synchronism with both when the specified content file is a simultaneously recorded content file represented by one display mark. In order to perform editing synchronously for both contents, a common scale for both contents may be used. For example, the time position from the start point and the end point can be mentioned. Specifically, the elapsed time from the recording start time which is the starting point may be edited together with both contents. As a more specific example, a case where the commercial part (1701) is synchronously removed from two contents recorded using FIG. 17 will be described. When deleting a commercial part, normally, after setting commercial start time A and end time B, the deletion is instructed. At this time, the content editing means calculates the elapsed time from the recording start time (START) of the content based on the set commercial start time A and end time B. Here, if each elapsed time is 15 minutes and 18 minutes later, the corresponding parts are removed after 15 minutes and 18 minutes from the start time of both contents, thereby synchronizing both contents. Editing is possible.

  <Fifth Embodiment: Hardware Configuration> The hardware configuration of the fifth embodiment is the same as the basic hardware configuration of the first embodiment shown in FIG. The hardware configuration of the content editing means, which is a characteristic feature of the present embodiment, is, for example, that the CPU (0601) receives an editing operation command signal from the content operation input GUI unit and stores it in the nonvolatile memory. The stored content editing program is expanded in the work area of the volatile memory. In accordance with the editing operation command signal and the program, the CPU calls the target content file designated for editing from the recording non-volatile memory of the recording unit and executes the editing process. At this time, if the CPU receives a signal that the content file designated for editing is associated with another content file, the CPU extracts a signal that is a common scale from both content files. For example, the time position of the start point of the edit location in the edit operation command is calculated from the recording start time information common to both content files. Edit processing is executed synchronously with respect to the two content files recorded simultaneously based on the calculated time position. As described above, the recording apparatus of the present embodiment can be realized.

  <Fifth Embodiment: Process Flow> An example of a recording method according to the present embodiment will be described with reference to FIG. FIG. 18 shows a flowchart of the recording method of the present embodiment. First, the recording apparatus receives an input of an editing operation via a display mark (S1801 editing operation input receiving step). Next, it is determined whether the one display mark that has received the input of the editing operation is a display mark having two content files recorded simultaneously (S1802 second display mark determination step). If the determination result in the second display mark determination step (S1802) is a determination result that is not a display mark for displaying two contents (No in S1802), normal editing processing is executed on the content (S1804 normal) Content editing step). In the case where the determination result in the second display mark determination step (S1802) is a determination result indicating that the two contents are displayed (S1802 Yes), the same applies to both of the two contents recorded simultaneously. The editing process is executed (S1803 both contents editing step). The recording method of the present embodiment can be achieved by the above processing flow.

The recording apparatus (2000) according to the present embodiment shown in this figure is based on the configuration of the recording apparatus of the third embodiment. That is, a digital broadcast receiving unit (2001), an analog broadcast receiving unit (2002), a recording command receiving unit (2003), a recording unit (2004), a control unit (2005), a content operation input GUI unit (2008), a management unit (2009), and the control unit further includes determination means (2006) and addition time control means (2007). Since the description regarding these structural requirements is the same as in the first to third embodiments, a description thereof will be omitted. A characteristic point of the configuration of the present embodiment is that the management unit (2009) further includes a content deletion unit (2010). Hereinafter, the configuration, function, and the like of the content deletion unit (2010) will be described.

  The “content deletion unit” (2010) deletes a content file held in the recording unit when the content operation input GUI unit receives an input of a deletion operation using a display mark. It is comprised so that it may have a function as a deletion means to do. In addition, when the content operation input GUI unit receives an input of a deletion operation for content using one display mark, the deletion processing of both of the two content files recorded simultaneously is executed.

As for the hardware configuration of the content deletion means that is a characteristic feature of the present embodiment, for example, the CPU (0601) receives a delete operation command signal from the content operation input GUI unit, and the nonvolatile memory The content deletion program stored in is stored in the work area of the volatile memory. In accordance with the delete operation command signal and the program, the CPU calls the target content file designated for deletion from the recording non-volatile memory of the recording unit and executes the deletion process. At this time, if the CPU receives a signal that the content file designated for deletion is associated with another content file, the CPU executes a deletion process for both content files. As described above, the recording apparatus of the present embodiment can be realized.

  <Sixth Embodiment: Process Flow> An example of a recording method according to the present embodiment will be described with reference to FIG. FIG. 21 shows a flowchart of the recording method of the present embodiment. First, the recording apparatus receives an input of a delete operation via the display mark (S2101 delete operation input receiving step).

  <Embodiment 6: Effect> According to the recording apparatus and the recording method of the present embodiment, it is possible to delete both of two broadcast contents simultaneously recorded by one deletion operation.

<< Embodiment 7 >>
<Embodiment 7: Overview> Embodiment 7 relates to a recording apparatus and a recording method. The recording apparatus and the recording method according to the present embodiment are based on the recording apparatus and the recording method according to the third to sixth embodiments. FIG. 22 is a diagram illustrating the concept of the present embodiment. In this figure, a monitor screen of a television to which the recording apparatus of this embodiment is connected is shown. In FIG. 22, two contents recorded simultaneously are displayed with one display mark (2201). When the recording apparatus according to the present embodiment selects the one display mark (indicated by a thick black frame) and inputs a content movement operation corresponding to the display mark from the screen button (2202), the digital broadcast content ( 2203), only the moving process (2205) is executed, and the deleting process (2206) is executed for the analog broadcast content (2204).

  <Embodiment 7: Configuration> FIG. 23 is a functional block diagram of a recording apparatus according to the present embodiment. The recording apparatus (2300) according to the present embodiment shown in this figure is based on the configuration of the recording apparatus of the third embodiment. That is, a digital broadcast receiving unit (2301), an analog broadcast receiving unit (2302), a recording command receiving unit (2303), a recording unit (2304), a control unit (2305), a content operation input GUI unit (2308), a management unit (2309), and the control unit further includes determination means (2306) and addition time control means (2307). Since the description regarding these structural requirements is the same as in the first to third embodiments, a description thereof will be omitted. A characteristic point of the configuration of the present embodiment is that the management unit (2309) further includes content moving means (2310). Hereinafter, the configuration, function, and the like of the content moving unit (2310) will be described.

  When the content operation means (2310) receives an input of a movement operation using one display mark in the content operation input GUI unit, the digital broadcast content among the two content files recorded simultaneously. The migration process is executed only for the file, and the deletion process is executed for the analog broadcast content file. The digital broadcast content file that is the target of movement processing by the content moving means refers to a copy-once content file. This is because the movement “move” is a concept for digital broadcast content in which the number of copies is limited to one, that is, copy-once content as described in “Background Art”. Therefore, when two content files consisting of a digital broadcast content with no limit on the number of copies and an analog broadcast content that is a simulcast are displayed with one display mark, the content file is not a target content file. . A copy-once content determination unit may be provided for determining whether the digital broadcast content file is a copy-once content file when a move operation is input to one display mark that displays two simultaneously recorded content files. . The determination device can make the determination by reading the copy control signal in the digital broadcast content file. Note that, after the movement process, neither content remains in the moving source recording apparatus, so the display mark at the position where both contents are displayed is also deleted.

  <Seventh Embodiment: Hardware Configuration> The hardware configuration in the seventh embodiment is the same as the hardware configuration in the first embodiment shown in FIG. As for the hardware configuration of the content moving means that is a characteristic feature of the present embodiment, for example, the CPU (0601) receives a movement operation command signal from the content operation input GUI unit, and the nonvolatile memory The content transfer program stored in the volatile memory is expanded in the work area of the volatile memory. The CPU searches whether the target content file designated for movement is a copy-once content file according to the movement operation command signal and the program. If the result of the search is “copy once content file”, the content file is called from the recording non-volatile memory of the recording unit, and the moving process is executed. At the same time, the analog broadcast content file associated with the copy-once content file is also called from the recording non-volatile memory of the recording unit and the deletion process is executed. As described above, the recording apparatus of the present embodiment can be realized.

  <Seventh Embodiment: Process Flow> An example of a recording method according to the present embodiment will be described with reference to FIG. FIG. 24 shows a flowchart of the recording method of the present embodiment. First, the recording apparatus receives an input of a moving operation via the display mark (S2401 moving operation input receiving step). Next, it is determined whether the one display mark that has received the input of the movement operation is a display mark having two content files that have been recorded simultaneously (S2402 fourth display mark determination step). If the determination result in the fourth display mark determination step (S2402) is a determination result that is not a display mark for displaying two contents (No in S2402), the processing for the content ends. When the determination result in the fourth display mark determination step (S2402) is a determination result that the display mark is for displaying two contents (Yes in S2402), the moving process is executed only for the digital broadcast content ( S2403 Digital broadcast content transfer processing step). Subsequently, a deletion process is executed for the analog broadcast content (S2404 analog broadcast content deletion process step). The recording method of the present embodiment can be achieved by the above processing flow. Note that the order of processing of the digital broadcast content movement processing step (S2403) and the analog broadcast content deletion processing step (S2404) is not limited. For example, the analog broadcast content deletion processing step (S2404) may be performed prior to the digital broadcast content movement processing step (S2403), or the two steps may be performed simultaneously.

  <Embodiment 7: Effects> According to the recording apparatus and the recording method of the present embodiment, only digital broadcast content is moved by one moving operation, and analog broadcast content simultaneously recorded with the digital broadcast content is automatically deleted. Is done. Conveniently, there is no need to separately perform deletion processing on the analog broadcast content left by the movement processing.
