  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same parts are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated.

  The hard disk recorder 10 in FIG. 1 incorporates two types of digital recording media playback devices, and supplies various contents supplied from the recording media such as video signals or audio to a monitor device 14 connected in advance to the outside of the device. It is a device that outputs a signal so that it can be viewed. The remote controller (abbreviated as a remote controller) 12 is a device operated by a user to input various commands, and transmits an infrared signal corresponding to the commands.

  The hard disk recorder 10 includes a DVD (Digital Versatile Disc) reading unit 20, an HD (Hard Disk) device 22, a tuner 24 that connects an external antenna 60 that receives a digital broadcast signal transmitted from a broadcast station, and an OSD ( On Screen Display) 50, a decoder 26, a memory 28, a video output unit 30, an audio output unit 32, a remote control receiving unit 34, a control unit 36, and an external device for supplying digital information from the outside And an external I / F (Inter Face) 38 for connecting 70.

  The DVD reading unit 20 is a device that reads information of digital contents recorded on an optical disc (in this embodiment, a DVD disc). In the case of this embodiment, arbitrary information (in the case of this embodiment, digital content information) is recorded on the DVD disc.

  The HD device 22 is a device that records a digital content signal desired by a user on the hard disk 42 and reads the recorded digital content signal. Here, examples of the signal recorded on the hard disk 42 include a video file conforming to the MPEG2 (Motion Picture Experts Group 2) standard and an audio file conforming to the MP3 (MPEG-1 Audio Layer3) standard.

  When the tuner 24 receives a digital broadcast signal transmitted from a broadcasting station via the antenna 60, the tuner 24 extracts and outputs a broadcast signal (digital content signal) of a channel designated by the control unit 36.

  The decoder 26 is a digital content signal reproduced by the DVD reading unit 20, a digital content signal read by the HD device 22 from the hard disk 42, a digital content signal received by the tuner 24, and an external device via the external I / F 38. When any one of the digital content signals input from 70 is given by the switching control of the control unit 36, the given digital signal is inputted, decoded (decoded) and outputted. The OSD 50 built in the decoder 26 generates image data based on the information given by the control unit 36 and outputs it to the video output unit 30 for visual display on the screen of the monitor device 14.

  In the memory 28, broadcast channels that can be received by the tuner 24 are acquired and stored in advance by channel scanning (auto-scanning), and an operation program of the control unit 36 is stored. The memory 28 also stores flags and data for information processing described later.

  The audio output unit 32 converts the audio signal decoded by the decoder 26 into an audio signal that can be output by the monitor device 14 and outputs the audio signal to the monitor device 14. The remote control receiving unit 34 receives various command signals transmitted from the remote control 12 via infrared rays and transmits the command signals to the control unit 36. The control unit 36 controls each unit of the apparatus based on the operation program stored in the memory 28.

  The HD device 22 includes a read head 44 for reading any of information constituting a program recorded on a recording medium (hard disk 42 in the present embodiment), and a recording head 46 for recording information on the recording medium.

  Referring to FIG. 2, the program executed by hard disk recorder 10 has the following control structure for setting the title format.

  In step 100 (hereinafter, step is abbreviated as “S”), remote control receiving unit 34 receives a signal from remote control 12. When the signal is received, the remote control receiver 34 outputs an electrical signal corresponding to the received signal to the controller 36. When the electrical signal is output, the control unit 36 determines whether or not the signal received from the remote controller 12 represents a title change by the user. If it is determined that the change represents a title change (YES in S100), the process proceeds to S102. If not (NO in S100), the process proceeds to S104.

  In S102, control unit 36 causes OSD 50 to generate data for a title format setting screen. When the setting screen data is generated, the control unit 36 causes the OSD 50 to output the data. The output data is output to the monitor device 14. The monitor device 14 displays an image corresponding to the data. When the data is displayed, remote control receiving unit 34 receives a signal from remote control 12. The remote control receiving unit 34 converts the received signal into an electrical signal. The remote control receiving unit 34 outputs the converted electric signal to the control unit 36. The control unit 36 decodes the signal output from the remote control receiving unit 34. The control unit 36 generates data representing the title format so as to correspond to the decoded signal. This data is temporarily stored in the memory 28. The control unit 36 causes the OSD 50 to generate display data representing the generated data. The generated display data is output to the monitor device 14. The monitor device 14 displays an image corresponding to the data. When the data control unit 36 decodes the fact that the key representing “return” on the remote controller 12 has been pressed (in this embodiment, the fact that the setting of the title format has been confirmed), the data representing the title format The contents of are confirmed. At S104, control unit 36 reads data representing a basic title format from memory 28.

  In S106, control unit 36 determines whether or not the program designated by the user in S100 is a recorded program. If it is determined that the program has been recorded (YES in S106), the process proceeds to S108. If not (NO in S106), the process proceeds to S112.

  In S108, the read head 44 of the HD device 22 reads information that becomes a part of the title from the hard disk 42 (the data read at this time is referred to as “recording information data”). In S110, control unit 36 creates information representing the title so as to correspond to the title format. When the information representing the title is created, the control unit 36 controls the recording head 46 so as to overwrite the information representing the title created by itself. The recording head 46 records the information on the hard disk 42.

  In S112, the control unit 36 refers to the information recorded by the HD device 22 to determine whether or not the reserved recording has ended. If it is determined that the reserved recording has ended (YES in S112), the process proceeds to S108. If not (NO in S112), the process proceeds to S114. In S114, control unit 36 waits until the scheduled recording ends. The time at which the reserved recording ends is stored in the memory 28.

  The operation of the hard disk recorder 10 based on the structure and flowchart as described above will be described.

[When the user sets the title format]
The control unit 36 determines whether or not the user has transmitted a signal to set the title format (S100). In this case, since the user has transmitted a signal to set the title format (YES in S100), control unit 36 causes OSD 50 to generate data for the title format setting screen. When the setting screen is displayed on the monitor device 14, the control unit 36 accepts transmission by the user. FIG. 3 is a diagram showing a screen for setting the title format generated by the OSD 50 according to the present embodiment. This screen is a screen for accepting input of a title format for a program selected by the user (including a program to be reserved and a recorded program). This screen displays the default format until it accepts the format input. If a title name has already been set, that title name is displayed. When the user transmits a signal using the remote controller 12, characters and marks corresponding to the signal are displayed in the title column (S102). In the case of FIG. 3, a character string “Tenka” and a mark indicating that the recording start date is to be inserted are displayed. In the case of FIG. 3, other marks that the user can select include “start time”, “end date”, “end time”, “recording time”, and “recording channel”. As is apparent from FIG. 3, in the case of the present embodiment, remote control receiving unit 34 receives a plurality of pieces of information representing any part of the format of the program title. The remote control receiving unit 34 divides the plurality of pieces of information into a predetermined order of at least two pieces of information in a program title format (the “predetermined order” in this embodiment is the order displayed on the screen). Accept as expressed according to). If information indicating the format of the title of the program and information indicating the position in the title of the format are transmitted, the remote control receiving unit 34 can receive the plurality of pieces of information without considering the order of the format. Therefore, the “predetermined order” is not limited to the order displayed on the screen as long as the order is predetermined. However, in the present embodiment, it is assumed that the plurality of pieces of information are received so that at least two pieces of information represent the format of the program title part by part in the order displayed on the screen.

  When the user transmits a signal indicating that the setting of the title format has been confirmed, the control unit 36 determines whether or not the program designated by the user has been recorded (S106). In this case, if the program designated by the user is a recorded program (YES in S106), read head 44 reads information that becomes a part of the title from hard disk 42 (S108).

  Referring to FIG. 4, the format of the program in the present embodiment includes a header area 80 and a data area 82. The header area 80 includes information for displaying and managing programs. The data area 82 includes video and audio data of the program. The header area 80 includes a recording information table 84 and a title area 86. The recording information table 84 includes data such as recording date and time. In the case of the present embodiment, information that becomes a part of the title is included in this recording information table 84. The title area 86 includes data representing a title and data for program reproduction. The recording information table 84 includes a date area 90, a start time area 92, an end time area 94, a time length area 96, a channel area 98, and an image quality area 100. The date area 90 represents the date when the recording of the program was started. In the present embodiment, the date is represented as “XX / XX”. “XX” represents a numerical value of a maximum of two digits. The start time area 92 represents the time when the recording of the program is started. In the present embodiment, the time is expressed as “AM XX: XX” or “PM XX: XX”. “AM” represents morning time. “PM” represents afternoon time. “XX” represents a numerical value of a maximum of two digits. The end time area 94 represents the time when the recording of the program ends. In the present embodiment, the time is also expressed as “XX: XX”. The time length area 96 represents the length of time that the program was recorded. In the present embodiment, the time is also expressed as “XX: XX”. A channel area 98 represents a channel on which the recorded program is broadcast. In the present embodiment, the channel is represented as “XX / XX”. “XX” represents a numerical value of a maximum of two digits. The image quality area 100 represents the image quality (XP mode, SP mode, etc.) set during recording. In the present embodiment, the image quality is represented as “X”. “X” represents a one-digit numerical value.

  When the information is read, the control unit 36 uses the information included in the recording information table 84 among the information constituting the program to create information representing the title so as to correspond to the format of the title. In the case of FIG. 3, if the recorded date is September 10, the title is “Tenka (09/10)”. When titles are created every time recording is performed, the titles are “Tenka (09/11)”, “Tenka (09/12)”, and so on. When the information representing the title is created, the control unit 36 controls the recording head 46 so as to overwrite the information representing the title created by itself. The recording head 46 records the information on the hard disk 42 (S110).

[When the user does not set the title format]
The control unit 36 determines whether or not the user has transmitted a signal to set the title format (S100). In this case, since the user does not transmit such a signal (NO in S100), control unit 36 reads data representing a basic title format from memory 28 (S104). FIG. 5 is a diagram showing a screen on which a basic title format is displayed. In the case of FIG. 5, if an 8-channel program from 4:14 pm to 5:14 pm on September 10 is reserved, the title is “09/10 PM04: 14 to PM17: 148CH”. Become. When the format data is read, the control unit 36 determines whether or not the file designated by the user is a recorded file (S206). In this case, if the file designated by the user is not a recorded file (NO in S106), control unit 36 determines whether or not the reserved recording has ended (S112). Initially, since the recording is not finished (NO in S112), the control unit 36 waits until the recording is finished (S114). Thereafter, the control unit 36 determines whether or not the reserved recording has been completed (S112). Eventually, recording ends (YES in S112), so that the read head 44 of the HD device 22 reads information that is part of the title from the hard disk 42 (S108).

  As described above, the hard disk recorder according to the present embodiment can set the title desired by the user so as to include information desired by the user. As a result, the set title is easy to understand for the user. As a result, it is possible to provide a recording apparatus that can set an easy-to-understand title even when many programs are recorded.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
