Description

  The present invention relates to a technique for recording data, and more particularly to a technique for recording a plurality of broadcast data based on the relationship between data.

  Among broadcast programs, there are programs that are broadcast in multiple times, such as dramas or series programs. When recording video / audio data including such a program on a VTR (Video Tape Recorder), HDD (Hard Disk Drive) device or other recording device, if the recording position is not designated, the recording is instructed. Recording is performed based on the state. For example, when video / audio data is recorded on the VTR, it is recorded on the tape from the position of the recording head, and when it is recorded on the HDD or DVD, it is recorded from the beginning of the recordable free space. Therefore, in order to record broadcast data at a predetermined recording position, it has been necessary to adjust the position of the tape so that the recording start position of the tape follows the recording end position of the already recorded broadcast data.

  In order to solve such problems, for example, Japanese Patent Laid-Open No. 2001-223974 (Patent Document 1) discloses a video recording apparatus that does not require the user to adjust the recording start position. The apparatus includes a randomly accessible recording medium, a designation unit for a user to designate a recording reservation, a circuit for managing a recording area of the recording medium, and a circuit for converting the designated recording reservation into a recording rule and holding the recording rule. A circuit for determining whether the recording condition is satisfied and a circuit for recording when the recording condition is satisfied.

According to this video recording apparatus, since a recording file area is allocated when recording is reserved by the user, it is possible to perform settings for recording video without adjusting the recording start position.

  By the way, there is a demand for a user to continuously play back a series of videos created as a series of video works such as a series drama.

  However, according to the video recording apparatus disclosed in Patent Document 1, for example, a literary work such as a serial drama is overwritten and saved in an area allocated in advance when recording is reserved. There was a problem that could not be played.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a data recording / reproducing apparatus that can continuously reproduce mutually related broadcast data. is there.

  In order to solve the above-described problem, according to one aspect of the present invention, a data recording / reproducing apparatus records means for receiving broadcast data including either video data or audio data, and the received broadcast data. A random accessible recording means for recording, a means for recording area data representing an area where broadcast data is recorded, a means for acquiring input information input by a user, and based on the input information Means for acquiring attribute data representing an attribute of the received broadcast data and, based on the acquired attribute data, the content of the received broadcast data is related to the content of the broadcast data already recorded A determination means for determining whether or not the content of the received broadcast data is related to the content of the already recorded broadcast data The area following the area indicating the corresponding region data in the broadcast data being, and a control means for controlling the recording means to record the received broadcast data.

  According to the data recording / reproducing apparatus having the above configuration, broadcast data including either video data or audio data is recorded in a randomly accessible recording means (for example, a hard disk recording / reproducing apparatus). When the input information input by the user is acquired, attribute data representing the attribute of the received broadcast data is acquired based on the input information. This attribute includes the type of broadcast data (drama, news, movie, etc.), whether the program is broadcast continuously (as a series), or the broadcast date and time. Based on the attribute data, the determining means determines whether the content of the received broadcast data is related to the content of the broadcast data already recorded. For example, when a code representing a drama broadcast in multiple times is included in the attribute data, it is determined that the broadcast data having the attribute data is related. The control means controls the recording means so as to record the received broadcast data determined as described above in an area subsequent to the area represented by the area data corresponding to the already recorded broadcast data. In this way, related broadcast data (for example, a drama broadcast every week or every day at the same time, news or other programs) can be continuously recorded in the recording means, so that the user reproduces the data. Even in this case, broadcast data having such a relationship can be continuously reproduced. Thereby, it is possible to provide a data recording / reproducing apparatus capable of continuously reproducing broadcast data having relevance to each other.

  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.

  With reference to FIG. 1, the structure of the data recording / reproducing apparatus 100 which concerns on embodiment of this invention is demonstrated. FIG. 1 is a block diagram showing a data recording / reproducing apparatus 100.

  The data recording / reproducing apparatus 100 includes a system control circuit 110, an OSD (On Screen Display) image generation circuit 114, an operation unit 122, a light receiving unit 124, a timing circuit 126, a display unit 128, a tuner 130, An MPEG (Moving Picture Experts Group) encoder 132, a hard disk device 140, an MPEG decoder 136, and an output unit 138 are included. The system control circuit 110 includes a memory 112. The hard disk device 140 includes a hard disk 144 and an information recording head 142.

  The data recording / reproducing apparatus 100 is, for example, an HDD (Hard Disk Drive) recorder, but is not limited thereto. For example, a PC (Personal Computer) including an HDD may be used. In this case, the operation of each unit is controlled based on a command from a CPU (Central Processing Unit) instead of a signal from the system control circuit 110.

  The data recording / reproducing apparatus 100 is connected to the television 150. Instead of the television 150, a display-only monitor or the like may be connected to the data recording / reproducing device 100 as a display device.

  The system control circuit 110 controls the operation of the data recording / reproducing apparatus 100 while inputting and outputting signals as will be described later. This operation includes recording of received video / audio data, reading of recorded data, and the like. This control is performed based on a program stored in advance in memory 112, for example.

  The OSD image generation circuit 114 displays a message image based on a user instruction acquired via the operation unit 122 or the light receiving unit 124, or when a predetermined condition is satisfied in the system control circuit 110. Generate a signal. The message image is a channel display, a recording setting screen display, a volume display, or other image, and is different from the image recorded on the hard disk device 140. When the OSD image generation circuit 114 generates such a message image signal, the OSD image generation circuit 114 outputs the message image signal to the output unit 138. When this signal is output, a message image represented by the signal is displayed on television 150.

  The operation unit 122 detects an instruction input by a user operation (for example, pressing a button). The operation unit 122 is, for example, an input button provided on the front panel of the data recording / reproducing apparatus 100, but is not limited thereto. When an instruction is detected, a signal for causing each unit to execute processing corresponding to the instruction is generated. This processing includes reception channel selection processing by the tuner 130, data reproduction, recording, and other processing. The generated signal is input to the system control circuit 110.

  The light receiving unit 124 receives a remote control signal emitted from a remote control terminal described later. This signal is input to the system control circuit 110.

  The timer circuit 126 measures the time in the data recording / reproducing apparatus 100. The timer circuit 126 operates based on power supplied from the outside, but can continue to operate for a preset time even if there is a temporary power failure. The clock circuit 126 outputs time data to the system control circuit 110. A control signal from the system control circuit 110 is input to this circuit. The time of the clock circuit 126 is corrected based on this signal.

  The display unit 128 displays information regarding the data recording / reproducing apparatus 100. This information includes items such as time, reception channel, counter, recording / playback mode, and the like. The display unit 128 is, for example, an indicator formed on the front surface of the data recording / reproducing apparatus 100, but is not limited thereto.

  An antenna 190 is connected to the tuner 130. The tuner 130 may be any tuner that can receive broadcast data such as analog broadcast and digital broadcast. The radio wave received by the tuner 130 is output to the MPEG encoder 132. Further, the tuner 130 can switch the reception channel based on a signal from the system control circuit 110.

  The MPEG encoder 132 converts the signal input from the tuner 130 into a digital signal and outputs the digital signal to the system control circuit 110.

  Based on the signal from the system control circuit 110, the hard disk device 140 writes MPEG encoded data to the hard disk 144 by the information recording head 142 and reads data recorded on the hard disk 144.

  The MPEG decoder 136 decodes the MPEG encoded data read from the hard disk device 140 and outputs the decoded data to the output unit 138.

  The output unit 138 outputs the signal from the OSD image generation circuit 114 and the signal from the MPEG decoder 136 to the television 150. As a result, the television 150 displays the image message generated by the OSD image generation circuit 114 and the video read from the hard disk device 140.

  With reference to FIGS. 2A and 2B, data recorded by the data recording / reproducing apparatus 100 according to the present embodiment will be described. FIG. 2A shows the structure of data recorded on hard disk 144. FIG. 2B shows the structure of data recorded on hard disk 144 when received data is further recorded on hard disk 144.

  This data is broadcast data representing a television broadcast or a radio broadcast received via the tuner 130, for example. Such broadcasting may be either analog broadcasting or digital broadcasting.

  As shown in FIG. 2A, “No.” for specifying the stored data record is stored in the field 202.

  Data representing the name of the program is stored in field 204. This data is sent along with the program to be transmitted, for example.

  Recording start disk No. Is stored in field 206. Recording start cylinder No. Is stored in field 208. Recording start track No. Is stored in field 210. The data items for specifying the recording start position are not limited to the above items, and may be any data item that can be uniquely specified.

  Similarly, the recording end disk No. Is stored in field 212. Recording end cylinder No. Is stored in field 214. Recording end track No. Is stored in field 216.

  The overwrite recording code is stored in the field 218. This code is a code indicating whether or not the data stored in this record can be overwritten.

  As shown in FIG. 2A, in the hard disk device 140, programs received in the order of “drama 1 episode”, “drama 2 episode”, “variety”, and “movie” are recorded. In this case, for example, “Drama 2 episode” is recorded from the track “02” of the cylinder “20” of the disc “01” to the track “02” of the cylinder “40” of the disc. In this data, overwrite recording is “prohibited”.

  With reference to FIG. 2B, data when recorded by the data recording / reproducing apparatus 100 according to the present embodiment will be described. The data structure shown in FIG. 2B is the same as the data structure shown in FIG. Therefore, description thereof will not be repeated here.

  The data structure shown in FIG. 2B is such that a series program (for example, “drama 3 episode”) received via the tuner 130 continues to “drama 2 episode” by executing a program described later. Represents the case of recording. That is, data No. After “Drama 2 Episode” recorded as “2”, “Drama 3 Episode” is recorded as data No. “3”.

  In this case, the recording start position of the data of “Drama 3 episode”, that is, “recording start disk No.”, “recording start cylinder No.”, and “recording start track No.” are recorded in the “variety already recorded”. Is the same as the start position of “”, but the end position of the recording is stored according to the capacity of “Drama 3 episode” (fields 212 to 216). As a result, the data indicating the start position of the variety recording is data following the end position of the recording of the drama 3 episode.

  With reference to FIG. 3, a control structure of system control circuit 110 that realizes data recording / reproducing apparatus 100 according to the present embodiment will be described. FIG. 3 is a flowchart showing a procedure of processing executed by system control circuit 110.

  In step S302, system control circuit 110 detects a recording instruction. This detection is performed, for example, when the user operates a remote control terminal (not shown) and presses the recording button, or when the time of the clock circuit 126 reaches the reserved recording time.

  In step S304, system control circuit 110 acquires information on a program to be recorded based on a preset reception channel of tuner 130. This information may be transmitted, for example, accompanying a program, or may be acquired when a user presses a predetermined button and directly inputs attribute data about the program.

  In step S306, system control circuit 110 determines whether or not the program is a continuous drama. This determination is made based on, for example, acquired information or based on attribute data input by the user. In this case, if the information or attribute data includes a code indicating that it is a continuous drama, the program is determined to be a continuous drama. If it is determined that the program is a continuous drama (YES in step S306), the process proceeds to step S308. If not (NO in step S306), the process proceeds to step S310.

  In step S308, system control circuit 110 obtains the end position of the previously recorded program. This acquisition is performed, for example, by reading data representing the end position recorded in a predetermined area (fields 212 to 216) of hard disk device 140.

  In step S310, system control circuit 110 moves information recording head 142 of hard disk device 140 to its end position.

  In step S312, system control circuit 110 outputs an instruction to start recording the designated program. As a result, the program received via the tuner 130 is written to the hard disk 144 by the information recording head 142 via the MPEG encoder 132.

  In step S314, system control circuit 110 detects an instruction to end recording. This detection is performed, for example, when a preset recording end time is reached. Alternatively, it is performed when the user presses a recording end button.

  In step S316, system control circuit 110 outputs an instruction to end recording. Thereby, the writing of data to the hard disk 144 by the information recording head 142 is completed.

  In step S318, system control circuit 110 records the recording end position in a predetermined area of hard disk 144.

  With reference to FIG. 4, a control structure of the system control circuit 110 when a program recorded in the data recording / reproducing apparatus 100 is reproduced will be described. FIG. 4 is a flowchart showing a procedure of processing executed when system control circuit 110 reproduces a program. The following processing is executed, for example, when the user selects a continuous playback mode, which is one of the program playback modes, on the playback screen.

  In step S402, system control circuit 110 outputs an instruction to display a list of recorded files. As a result, the recording information recorded on the hard disk device 140 is displayed on the television 150. This recording information includes a data number, a program name, an attribute indicating that it is a continuous program, a recording time, a recording date and time, a recording mode, and the like.

  In step S404, the system control circuit 110 acquires the number of the file to be played back selected by the user. This acquisition is performed when the user presses a predetermined button on a remote control terminal (not shown).

  In step S406, the system control circuit 110 moves the information recording head 142 to a predetermined position based on the acquired file number. This position is the data recording start position.

  In step S408, system control circuit 110 outputs an instruction to reproduce the selected file. As a result, broadcast data recorded in a predetermined area of the hard disk device 140 is read and decoded by the MPEG decoder 136. The decrypted data is sent to the television 150 connected to the output terminal 138.

  In step S410, system control circuit 110 determines whether or not an instruction to end reproduction has been detected. This detection is performed, for example, when the user presses a stop button on the remote control terminal. If it is determined that an instruction to end reproduction has been detected (YES in step S410), the process proceeds to step S414. If not (NO in step S410), the process proceeds to step S412.

  In step S412, system control circuit 110 outputs an instruction to start playback of the next file. In this case, the continuous drama is recorded in a predetermined area of the hard disk 144 based on a predetermined order. Therefore, the next drama file is read without the movement of the information recording head 142.

  In step S414, system control circuit 110 outputs an instruction to end file reproduction. As a result, the information recording head 142 ends the data reading mode and switches to the standby state.

  In step S416, system control circuit 110 outputs an instruction to display the initial setting screen. When this instruction is output, an initial setting screen is displayed on the television 150. This screen is, for example, a reproduction menu or a preset blue background screen.

  The operation of data recording / reproducing apparatus 100 according to the present embodiment based on the above-described structure and flowchart will be described separately for data recording and reproduction.

[When recording data]
When the user inputs information for recording reservation, an instruction is detected from the information (step S302). Information on the program corresponding to the reception channel set based on the information is acquired (step S304). If the program is a continuous drama (YES in step S306), the end position of the drama recorded last time is acquired (step S308). The information recording head 142 of the hard disk device 140 is moved to a predetermined position (step S310), and recording is started (step S312). When the predetermined time comes and the recording is finished (step S316), the position at that time is stored in the hard disk device 140 (step S318).

  Thus, for example, when the received serial drama is the third broadcast, it is recorded on the hard disk 144 following the second program already broadcast and recorded. That is, as shown in FIG. 2B, “drama 3 episode” is recorded as program “No. 3” after “drama 2 episode” recorded as program “No. 2”.

[When playing back data]
When a user operates a remote control terminal (for example, when a predetermined menu is selected by displaying a reproduction menu) and a program recorded on the hard disk device 140 is reproduced, the television 150 has a list of predetermined files. It is displayed (step S402). When the user selects a program from the list, the information recording head 142 of the hard disk device 140 moves to a predetermined position corresponding to the file number corresponding to the program (step S406).

  When playback of the program starts (step S408), the next file is played back (step S412) unless the user instructs the end of playback (NO in step S410). For example, as shown in FIG. 2B, when the user is watching the second drama, when the drama ends, the third drama is continuously played.

  Thereafter, when the user operates the remote control terminal to instruct the end of playback (step S414), an initial playback screen is displayed on the television 150.

  As described above, based on the detected recording instruction, data recording / reproducing apparatus 100 according to the present embodiment acquires information on a program broadcast on a channel corresponding to the instruction. If it is determined that the program is a continuity program (for example, continuously drama, news, etc.) based on the information, the position already recorded for the program is read, and then the program is recorded. To do.

  In this way, since a continuously broadcast program such as a series drama or series program is recorded continuously in a predetermined area of the hard disk 144, such information can be continuously played back during playback. it can. Accordingly, it is possible to provide a data recording / reproducing apparatus capable of continuously reproducing videos having relevance to each other.

<Second Embodiment>
Hereinafter, a second embodiment of the present invention will be described. The hardware configuration of the data recording / reproducing apparatus 100 according to the present embodiment is the same as that of the first embodiment. Therefore, detailed description thereof will not be repeated here.

  The data recording / reproducing apparatus according to the present embodiment is different from the first embodiment described above in that mutually related information is not necessarily continuously recorded on the hard disk 144.

  The data recorded on the hard disk 144 will be described with reference to FIG. FIG. 5A shows an arrangement of video information recorded on hard disk 144. FIG. 5B shows a table structure storing data representing the positional relationship of the information.

  Referring to FIG. 5A, “Drama 1 episode” is recorded in sector 502. “Drama 2 episode” is stored in the sector 504. “Another drama” different from these dramas is stored in the sector 506. Similarly, the recorded video information is written in the hard disk 144 in the recording order. Here, the sector refers to a unit of data recording in the hard disk 144.

  Referring to FIG. 5B, the program number is stored in field 522. The name of the program is stored in field 524. Recording start disk No. Is stored in field 526. Recording start cylinder No. Is stored in field 528. Recording start track No. Is stored in field 530. Recording end disk No. Is stored in field 532. Recording end cylinder No. Is stored in field 534. Recording end track No. Is stored in field 536. Group No. Is stored in field 538. This group No. Is a number for specifying the group to which the video recorded in each sector belongs. This number may be set automatically based on information sent with the reception of the video, or may be set based on information input by the user.

  The playback order is stored in field 540. This reproduction order represents the order of reproduction when the user inputs a reproduction instruction. That is, when video information belonging to the same group is recorded, the video information is reproduced in ascending order of numbers based on this reproduction order.

  With reference to FIG. 6, a control structure of system control circuit 110 realizing data recording / reproducing apparatus 100 according to the present embodiment will be described. FIG. 6 is a flowchart showing a procedure of processing executed by system control circuit 110. Note that the same steps as those in the first embodiment described above are denoted by the same step numbers, and description thereof will not be repeated.

  In step S604, system control circuit 110 obtains the recording start position. This acquisition is performed by reading the recording end position of the program recorded in a predetermined area of the hard disk 144.

  In step S606, the system control circuit 110 moves the information recording head 142 to the start position.

  In step S618, system control circuit 110 obtains program information corresponding to the reception channel. This acquisition is performed, for example, by acquiring the program information from the accompanying information transmitted together with the video information.

  In step S620, system control circuit 110 determines whether the program is a continuous drama. This determination is made based on the program information acquired in step S618. If the program is a continuous drama (YES in step S620), the process proceeds to step S622. Otherwise (NO in step S620), the process proceeds to step S624.

  In step S622, system control circuit 110 generates the reproduction order as file attribute information. This generation is performed, for example, so as to be associated with the playback order of the previously recorded program already recorded on the hard disk 140.

  In step S624, system control circuit 110 generates general attribute information. The general attribute information is, for example, a recording date and time or a recording mode.

  In step S626, system control circuit 110 records the attribute information in a predetermined area of hard disk device 140.

  With reference to FIG. 7, the control structure of the system control circuit 110 when reproducing the video recorded in the data recording / reproducing apparatus 100 will be described. FIG. 7 is a flowchart showing a procedure of processing executed by system control circuit 110. The same processes as those shown in FIG. 4 are denoted by the same step numbers, and description thereof will not be repeated here.

  In step S708, system control circuit 110 starts playback of selected file A.

  In step S 710, system control circuit 110 reads the reproduction number of file A from hard disk device 140.

  In step S712, system control circuit 110 searches for file B having the next number after the reproduction number.

  In step S714, system control circuit 110 determines whether reproduction of file A has ended. This determination is made based on whether or not a predetermined signal (for example, a signal indicating the end of data recording) is detected via information recording header 142 of hard disk device 140, for example. If it is determined that reproduction of file A has ended (YES in step S714), the process proceeds to step S718. If not (NO in step S714), the process proceeds to step S716.

  In step S716, system control circuit 110 continues to play the file.

  In step S718, system control circuit 110 determines whether or not file B searched in step S712 exists. This determination is made based on, for example, whether or not a code representing the file B has been acquired or whether or not a code indicating that the corresponding file does not exist has been acquired by the search. If file B exists (YES in step S718), the process proceeds to step S720. If not (NO in step S718), the process proceeds to step S722.

  In step S720, system control circuit 110 starts reproduction of file B. Thereby, the program corresponding to the file B is displayed on the television 150 following the program corresponding to the file A.

  In step S722, system control circuit 110 detects the end of reproduction. This detection is performed, for example, when the user presses the stop button on the remote control terminal or when the file B is played to the end.

  In step S724, system control circuit 110 outputs an instruction to display an initial screen. As a result, a preset blue background screen or menu selection screen is displayed on the television 150.

  The operation of the data recording / reproducing apparatus according to the present embodiment based on the above-described structure and flowchart will be described for the case of recording data and the case of reproducing data.

[When recording data]
When the user presses the recording button, the instruction is detected (step S302). The recording starts (step S312), and when the user presses the recording end button (step S314), program information is acquired when the recording ends (step S618).

  If the program is a continuous drama (YES in step S620), a playback order is generated and recorded in a predetermined area of hard disk 144, that is, an area for storing the playback order as data (step S626).

[When playing back data]
The user operates the remote control terminal to display a file list (step S402). When the user selects a file number to be viewed, the selection result is acquired (step S404). Playback of the selected file A is started (step S708), and the playback number of file A is read during playback (step S710).

  While the file A is being reproduced, the file B having the next number of the reproduction number is searched (step S712), and when such a file B is recorded (YES in step S718), the file A File B is reproduced after reproduction (step S720). In this way, file B is reproduced following file A.

  As described above, according to the data recording / reproducing apparatus of the present embodiment, when video information (for example, a continuous drama or a series program) is recorded, it is reproduced as attribute information related to each program information. The order is recorded. In this way, since the program can be reproduced based on the reproduction order without being continuously recorded on the hard disk device 140, the user can view the continuous program continuously. Accordingly, it is possible to provide a data recording / reproducing apparatus capable of continuously reproducing videos having relevance to each other.

<Modification>
Hereinafter, modifications of the embodiment of the present invention will be described. The first and second embodiments described above are for the case where the recording means for recording data is a hard disk device, but the present invention can be applied to a randomly accessible recording means such as a hard disk device. Not limited. For example, the data may be recorded on a video tape or other serially accessible recording means.

  That is, at the time of data recording (recording), the user inputs data attributes, and based on the attributes and the control signal recorded on the video tape, the data recording area and contents (for example, in a continuous drama) And the like may be stored as management data in a memory provided in the video tape case. Alternatively, management data including contents and attributes recorded at the head of the tape may be recorded for a video tape that does not have such a memory.

  With reference to FIG. 8, the management data according to the present modification will be described. FIG. 8 shows a structure of a table in which management data is stored. This table may be stored in a memory provided in the case of the video tape, or may be stored in a memory of the data recording / reproducing apparatus.

  Number data representing the record number of the management data is stored in field 802. This number data is automatically set when a new program or the like is recorded.

  The recording start time data is stored in the field 804. The recording end time data is stored in the field 806. These time data are time data output from the time measuring circuit 126. For example, time data when the system control circuit 110 outputs a recording start instruction is acquired as recording start time data. Similarly, time data when the system control circuit 110 outputs a recording end instruction is acquired as recording end time data and stored in a predetermined field.

  Title data is stored in field 808. When this data is included in the broadcast data, the data is stored. When the user can input data using a remote control terminal (not shown), the input data is stored.

  The recording channel data is stored in the field 810. This data represents the reception channel of the tuner set when receiving a program.

  The recording mode data is stored in the field 812. This data represents a mode when a program is being recorded. This mode includes, for example, a standard mode, a triple mode, and the like.

  In the data recording / reproducing apparatus having such a configuration, when a user inputs in advance an attribute of data to be received, whether or not the attribute is related to an attribute of data stored in this table (for example, continued). For example, a program broadcasted at the same time every week). This determination is made, for example, by comparing codes representing the attributes. When it is determined that the data to be received is related to the data already recorded on the video tape, the recording end position of the data recorded on the video tape is determined based on the management data recorded in the memory. Is done.

  As described above, according to the data recording / reproducing apparatus of the present modification, data to be newly received is recorded continuously at the end position where the data has been cued. It can be played as it is without fast-forwarding.

  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.
