In addition, it is possible to provide a storage medium and a recording / reproducing apparatus capable of easily exchanging contents among a plurality of recording media.

  Hereinafter, a case where the content is a program broadcast by terrestrial digital broadcasting will be described as an example.

  FIG. 1 is a configuration diagram illustrating an example of a content processing system. The book 1 is a recording / playback apparatus that records and plays back video and audio, and may be either a portable type or a stationary type. Reference numeral 2 denotes a recording medium capable of recording digital data, for example, a memory card equipped with a readable / writable flash memory. Details of the configuration of the recording / playback apparatus 1 and the recording medium 2 will be described.

  First, the configuration of the recording / playback apparatus 1 will be described. The receiving unit 5 selects a radio wave received by the broadcast receiving antenna 4 and extracts content data as digital data. Here, when the content data is encrypted or compressed, the receiving unit 5 decrypts or decompresses the content data. The control unit 6 performs various controls of the recording / reproducing apparatus 1, and includes a data processing means 7 that performs processing such as converting content data sent from the receiving unit 5 into reproducible data, and processing. A recording / reproducing unit 8 for reproducing and recording the content data, and a content list generating unit 9 for generating a list of recording times and titles of the recorded content data.

  The storage unit 10 stores the content recorded by the recording / reproducing unit 8, the content list created by the content list generating unit 9, and the like. The operation unit 11 is, for example, a button or a touch panel, and the user uses the operation unit 11 to input a channel selection instruction from the reception unit 5, a recording / reproduction instruction to the recording / reproducing unit 8, and the like. The display unit 12 includes, for example, a liquid crystal display, and displays content, an operation menu screen, and the like.

  The recording medium RW unit 13 records the content data output from the recording / playback processing unit 8 on the recording medium 2 or reads the content data recorded in the recording medium 2 in accordance with an instruction from the control unit 6. The RF tag RW unit 14 communicates with the RF tag in a non-contact manner, and reads and writes data of the RF tag. Note that the RF tag is an information medium such as an RFID (Radio Frequency Identification) or a wireless IC tag that reads and writes a built-in memory in a non-contact manner using radio waves or electromagnetic waves called in various ways.

  The recording medium 2 includes a memory card unit 21 that is connected to the recording medium RW unit 13 and exchanges data such as contents, and an RF tag unit 22 that is wirelessly connected to the RF tag RW unit 14 and transmits and receives data. The memory card unit 31 includes a terminal unit 23 for connecting to the recording medium RW13, a control unit 24 for reading data requested by the recording medium RW13, and a memory unit 25 for recording data. For example, content 26 is recorded in the memory unit 25. The RF tag unit 22 includes a memory unit 29 for recording data, an antenna 27 for communicating with the RF tag RW unit 14 of the recording / reproducing apparatus 1, a control unit 28 for reading data according to a request from the RF tag RW unit 14, It consists of. In the memory unit 29, for example, ID 30 that is a unique identifier of the RF tag unit 22, content information 31 of content recorded in the memory unit 25 of the memory card unit 21, and the like are recorded.

  FIG. 2 shows an example of a memory map in the memory unit 29 of the RF tag unit 22. The memory map 40 includes an ID storage area 41, an RF tag information area 42, a memory card information area 43, and a content information storage area 44. The ID storage area 41 is an area for storing the unique ID 30. For example, the ID storage area 41 is an area that can be read once written at the time of shipment of the recording medium but cannot be rewritten. In the RF tag information data storage area 42, data for determining the type of the RF tag 22 is stored, and in the memory card information area 43, information such as the capacity and remaining capacity of the memory 25 of the memory card unit 21, memory card access history, etc. Is stored. In the content information storage area 44, information corresponding to items such as the title and recording date and time of the content stored in the recording medium 2 is stored in a capacity and order determined for each item. For example, if the title character has 40 bytes and the recording date and time is 8 bytes, the recording / playback apparatus 1 can read the content information via the RF tag RW14 if they are recorded in the order of the determined items. Is possible.

  FIG. 3 shows an example of content information recorded in the memory 29 of the RF tag unit 22. In this example, the content information includes information corresponding to items such as the title 51, the genre 52, the recording date and time 53, and the recording time 54 for each of the contents 55, 56, and 57 recorded in the memory unit 25 of the recording medium 2. It is recorded.

  For example, each item information of each content information can be arbitrarily set by describing the number of stored content information and the capacity value corresponding to the item of the content information at the beginning of the content information area or the memory card information area. Can be set. The genre 52 or the like may be recorded as character data, or a number corresponding to the genre may be determined in advance, and the corresponding number may be recorded. In addition, in the portion where there is no content information, for example, as shown in the genre of the content “mysterious world” 51, “−” display or display indicating that there is no data may be used. The reading of the content information of the recording medium 2 by the recording / reproducing apparatus 1 described above will be described.

  FIG. 4 shows an example of a content information read processing flow. First, the RF tag RW unit 14 of the recording / reproducing apparatus 1 sends information necessary for communication on radio waves or magnetic fields, and searches for a communicable RF tag (S201). If the RF tag unit 22 is within a range where communication with the RF tag RW unit 14 is possible, power is generated by the radio wave or magnetic field of the RF tag RW unit 14 (S202), and the RF tag unit 22 responds to the RF tag RW unit 14. Return (S203). Next, the RF tag RW unit 14 acquires the RF tag information in the RF tag information data storage area 42 in order to confirm that the type of RF tag, here, the content information is a recordable RF tag. (S204). It is confirmed from the acquired RF tag information whether or not it is a corresponding RF tag (S205), and if it is not a corresponding RF tag, another RF tag is searched (S206). On the other hand, in the case of a corresponding RF tag, the RF tag RW unit 14 acquires an ID (S207), acquires memory card information (S208), and acquires content information (S209). The order of acquiring the ID in S207, acquiring the memory card information in S208, and acquiring the content information in S209 is not limited to the example shown in FIG. 4, and may be executed in a different order or simultaneously. May be. Further, when a plurality of recording media are read, the processing from the information transmission in S201 is repeatedly performed to acquire the content information of each recording medium. Through the above processing, the acquired content information is displayed as a content list on the display unit 12 of the recording / reproducing apparatus 1 (S210).

  As described above, in this example, in order to acquire the content information recorded in the memory 29 in the recording medium 2 by the RF tag RW unit 14 of the recording / reproducing apparatus 1, the recording medium 2 is inserted into the recording / reproducing apparatus 1. In addition, the content in the recording medium 2 can be easily confirmed without having to record the content information in advance in the recording / playback apparatus 1.

  FIG. 5 shows a display example of a content list displayed on the display unit 12 of the recording / reproducing apparatus 1. Reference numeral 61 denotes information for identifying a recording medium, that is, an ID is displayed. In this example, a number is displayed as the ID, but a character, a mark, or the like may be used. A content list display unit 62 displays a part or all of the content information shown in FIG. Here, the genre may be displayed as characters or may be displayed as an easy-to-understand icon. Reference numeral 63 denotes the remaining amount of recording media in the memory card information. Reference numerals 64, 65, and 66 denote operation buttons. By selecting an operation button from the operation unit, an operation desired by the user can be performed. For example, if there is content that the detailed display is desired to be viewed, the content to be viewed is selected from the content list, and the detail screen is displayed by selecting the 66 detail button. For example, the detailed screen displays within a range in the content list data such as a content change history and a detailed description of the content.

  Next, a procedure for writing content and content information to a recording medium will be described. FIG. 6 shows an example of a flow of processing for writing content and content information to a recording medium. Here, it is assumed that the recording medium 2 is inserted in the recording medium RW unit 13 of the recording / reproducing apparatus 1 in advance.

  When the recording medium 2 is selected as the content storage location (S301), the recording / reproducing apparatus 1 acquires the remaining memory capacity of the recording medium (S302), and whether the content type is streaming data acquired by streaming. In the case of streaming data, the recordable time is calculated from the remaining memory capacity of the recording medium 2 (S304), and the recordable time is displayed on the display screen (S305). When the content is not recorded in the recording / playback apparatus 1 or the like, the content capacity is compared with the remaining memory capacity of the recording medium 2 (S306), and the remaining memory capacity of the recording medium 2 is insufficient. If so, a memory shortage message is displayed (S307), and the user is prompted to replace the recording medium. When the remaining memory capacity of the recording medium 2 is sufficient or when it is streaming data, the recording / reproducing apparatus 1 writes the content into the recording medium 2 (S308), and after the writing is completed, obtains the remaining memory capacity of the recording medium 2 again. (S309).

  Next, a content information acquisition process for acquiring content information from the recording medium 2 is performed (S310). The content information acquisition process in S310 is the same as the process in S201 to S209 in FIG. If the content list data has already been acquired, S310 may be omitted. Then, the content information of the content previously written on the recording medium 2 is added to the acquired content list data and written to the content list data area. Furthermore, the remaining memory capacity information acquired in S309 is written (S313).

  Through the processing described above, the recording / reproducing apparatus 1 can write content information corresponding to the content recorded on the recording medium 2 in the RF tag unit 22 of the recording medium 2. Further, when the user wants to confirm what content is recorded on the recording medium 2 later, the user can know the contents of the recorded content without inserting the recording medium 2 into the recording medium RW13 of the recording / reproducing apparatus 1. be able to.

  FIG. 7 shows another configuration example of the recording medium. The recording medium 220 is obtained by adding a switch 221 between the memory card unit 21 and the RF tag unit 22 to the recording medium 2 shown in FIG. The same parts as those in FIG.

  In the recording medium 220, when power is supplied to the terminal of the memory card unit 21, that is, when the recording medium 220 is inserted into the recording medium RW unit 13 in the recording / playback apparatus 1, The control unit 24 and the memory 29 of the RF tag unit 22 are connected. Otherwise, the control unit 28 of the RF tag unit 22 and the memory 29 are connected. As a result, when the recording medium 220 is inserted into the recording medium RW unit 13 of the recording / reproducing apparatus 1, the recording medium RW13 can read and write to the memory 29 of the RF tag unit 22. As described above, when the recording medium 220 is inserted into the recording medium RW unit, the recording medium RW unit 13 reads and writes data in the memory 29 instead of the RF tag RW unit 14 to insert the recording medium RW 13 into the recording medium RW 13. It is possible to prevent content information from being written to a nearby recording medium, which is different from the recording medium used. Further, depending on the attachment position of the RF tag unit 22, there is a possibility that the RF tag RW 14 cannot communicate with the RF tag unit 22 even when the recording medium 220 is inserted into the recording medium RW unit 13. For this reason, when the recording medium 220 is inserted into the recording medium RW unit, content information to the recording medium 220 is read by writing to the memory 29 by the recording medium RW unit 13 instead of the RF tag RW unit 14. Can be reliably written.

  Next, a method for moving content between recording media will be described.

  FIG. 8 shows another configuration example of the content processing system. The recording / playback apparatus 601 is the same as the recording / playback apparatus 1 shown in FIG. 1, except that content editing processing means 602 that deletes the contents of the storage media and moves and copies the contents between the storage media is added. The same parts as those in FIG. Hereinafter, content editing processing in the content editing processing unit 602 will be described.

  FIG. 9 is a display example on the display unit 12 of the recording / reproducing apparatus 601 that has read the content list for three recording media. 3 is an example of content information of the first recording medium, FIG. 10A is an example of content information of the second recording medium, and FIG. 10B is an example of content information of the third recording medium. Here, in FIG. 9, the same reference numerals are given to the same components as in FIG. 5, and in FIG. 10, the same components as in FIG.

  In this example, content 58 and content 59 are recorded on the second recording medium as shown in FIG. 10 (1), and content 60 is stored on the third recording medium as shown in FIG. 10 (2). It is recorded. Reference numerals 71, 72, and 73 in FIG. 9 denote tabs corresponding to the respective recording media, which indicate the ID of the first recording medium, the ID of the second recording medium, and the ID of the third recording medium, respectively. The content list with the ID is displayed at the top. FIG. 9 shows an example in which the content list of the first recording medium is displayed in the content list 62. Here, when the tab 72 is selected, the content list of the second recording medium is displayed, and when the tab 73 is selected, the content list of the third medium is displayed. When the edit button 65 is selected, the edit mode is activated and the content editing processing means 602 starts the content editing process.

  FIG. 11 shows an example of a display screen on the display unit 12 of the recording / playback apparatus 601 during the content editing process. The same components as those in FIG. 5 or FIG. In FIG. 11, 81, 82, 83, 84, 85, 86, 87, and 88 are buttons for editing operations, 89 is a content list of the third recording medium, and 90 is a storage capacity of the third recording medium. Indicates the remaining amount.

  When the move button 81 is selected, the content move setting is enabled. When the copy button 82 is selected, the content copy setting is selected. When the delete button 83 is selected, the content delete setting is selected. When the change button 84 is selected, the content information can be changed. Become. When the operation cancel buttons 85 and 88 are operated, for example, the previous operation is canceled. By selecting the execution button 87, the content information is moved or copied between the content lists. When the edit end button 86 is selected, if there is content that is being edited, the content is written to and read from the recording medium. Here, FIG. 11 (1) is an example of a display screen in which no edit processing button is selected, and FIG. 11 (2) is a case where the move button 81 or the copy button 82 of FIG. 11 (1) is selected. The example of a display screen in the case of a case is shown. In this example, only the buttons necessary for editing are shown, and there may be other operation buttons. The above buttons are not always displayed on the screen, but may be displayed in a pop-up when necessary. It doesn't matter.

  Next, the flow of the movement process will be described. FIG. 12 shows an example of the content movement processing flow.

  As shown in the display screen example in FIG. 11 (1), for example, when moving the content 55 of the first recording medium to the third recording medium, the user moves the cursor or the like to the title of the content 55. After selecting a certain “prima donna 1”, the move button 81 is selected (S401). In this example, in order to explain the content movement process, whether or not the movement button 81 is selected is detected in S401. However, when another button such as the copy button 82 is selected, the detection is performed in the same manner, and the corresponding action is taken. Process.

  When the selection of the move button 81 is detected in S401, the content selected by the cursor is recognized as the content to be moved, and a display requesting the user to select the recording medium to be moved is performed (S402). When the user selects the portion where the ID of the recording medium to be moved is displayed and presses the execute button 81 (S403), the user recognizes the recording medium at the move destination and asks for confirmation as to whether or not to end editing. Display is performed (S404). In this state, the content on the actual recording medium is not moved, but on the screen display, for example, the character color or shading is changed or the mark is changed so that the user can know the content scheduled to move on the content list. It is desirable to display such as adding characters or to blink characters or marks.

  When the end button 86 is selected (S405 YES), for example, a message as shown at 611 in FIG. 13 is displayed to prompt the user to insert a recording medium on which content to be moved is recorded (S406). When the recording medium is inserted (YES in S407), the recording / playback apparatus 601 confirms that the recording medium is correct, reads the content selected as the moving content from the inserted recording medium, and stores it in the storage unit 10. . When the storage of the content in the storage unit 10 is completed, the content is deleted from the recording medium. If the user selects the copy button 82 instead of the move button 81, the content is not deleted. If the delete button 83 is selected, the content is erased from the recording medium, and the process ends.

  After the content is stored in the storage unit 10 in S408, a message prompting the user to insert the destination recording medium is displayed (S409). When the user inserts another recording medium (YES in S410), it is confirmed that the recording medium is correct, and the content stored in the storage unit 10 is recorded on the inserted recording medium (S411).

  In this example, the case where one content is moved between two recording media has been described. However, the present invention is not limited to this, and may be used when a plurality of contents are moved between two or more recording media. good. In this case, the selection of the moving content and the movement destination in S401 to S404 is repeatedly performed, and the processes in S406 to S411 are repeated until it is determined in S412 that the movement has been completed.

  Note that when a user inserts a recording medium, the recording medium has the same outer shape, and therefore it may not be clear which recording medium is requested to be inserted. Therefore, when the recording medium is held over the RF tag RW unit 14, the ID of the held recording medium may be displayed in addition to the message, as indicated by 612 in FIG.

  As described above, according to the method described above, it is possible to easily move and copy content between recording media. Further, a method for efficiently performing content movement or copying processing between recording media will be described. FIG. 15 is a diagram showing a conceptual diagram of content movement. For example, the content 26c is moved from the first recording medium 2a to the third recording medium 2c, the content 26e from the second recording medium 2b is moved to the first recording medium 2a, and the content 26d is moved to the third recording medium 2c. In this case, if the first recording medium 2a, the second recording medium 2b, and the third recording medium 2c are sequentially inserted, it is necessary to insert the first recording medium 2a again. Therefore, the content editing processing unit 602 determines the insertion order so that the number of insertions of the recording medium is the shortest, and displays the insertion message in the determined order. As an example of how to determine the insertion order, the first group is a recording medium having contents only at the movement source, the third group is a recording medium having contents at the movement destination, and the second is a recording medium having contents at the movement destination and the movement source. Recording media are inserted in the order of the first group, the second group, and the third group. In FIG. 13, the storage medium 2b is the first group, the storage medium 2a is the second group, the recording medium 2c is the third group, and the storage medium 2b, the storage medium 2a, and the recording medium 2c are inserted into the recording medium RW in this order. Thus, it is possible to efficiently move and copy content.

  Further, when the number of recording media is increased and a plurality of recording media correspond to each group, the order of inserting the recording media in the first group and the third group is not limited, but there are a plurality of recording media in the second group. If there is, you need to order them. As an example of how to determine the order within the second group, first, an arbitrary recording medium is selected and inserted at the beginning and end of the second group. Next, when the movement of the previously selected recording medium is ignored, only the movement source, the movement destination, or the movement source and the movement destination are the same as the first group and the second group. It is divided into a second group of two groups and a third group of second groups. If there are still a plurality of second groups, an arbitrary recording medium is selected again, and the order of insertion is determined by dividing the same group. FIG. 16 shows the order in which recording media are inserted into the recording media RW unit 13 of the recording / reproducing apparatus 601 when the second group of the second group is one or less. First, a message prompting the insertion of the recording medium of the first group is displayed, and the moving source content of the first group is inserted (S501). Next, a message prompting the user to insert an arbitrary recording medium in the second group is displayed, the content at the movement source of the arbitrary recording medium in the second group is read, and the content is written as necessary (S502). Thereafter, the contents are similarly read or written in the order of the first group of the second group, the second group of the second group, and the third group of the second group (S503 to S505). Finally, the content is written to an arbitrary recording medium of the second group and the third group, and the movement process is terminated (S506 to S507).

  As described above, the content editing processing unit 602 notifies the user of the storage medium to be inserted so that the number of insertions of the storage medium is as small as possible, thereby efficiently moving the content between the recording media. it can. Although the content movement has been described above, the content duplication is performed in the same manner.

  FIG. 17 shows an example of a configuration diagram of a recording medium. The recording medium 230 is obtained by adding content information generating means 101 to the recording medium 2 shown in FIG. The content information generation means 101 and the content data stored in the memory card unit 21 are analyzed, data necessary for content list generation is collected, and content list data is generated. By providing the content information generating unit 101 in the recording medium, the content list can be generated and stored on the recording medium side even when the content is recorded on the recording medium by a recording / reproducing unit having no content list generating function. .

  FIG. 18 shows an example of a display screen when a recording area of a recording medium name that can be registered by the user is provided in the memory section 29 of the RF tag section 22 of the recording medium. The user's favorite name 620 can be displayed in the portion where the recording medium ID is displayed, and the display is easy to understand. Note that a user can easily recognize a desired recording medium by attaching a name sticker to the recording medium. Furthermore, a voltage is applied to the surface of the recording medium to change the display, and when no voltage is applied, a liquid crystal film is disposed to hold the display, and when the recording medium is inserted into the recording / reproducing apparatus, the recording medium When a name is set, the name of the recording medium may be displayed on the recording medium as well.

  FIG. 19 shows a configuration example of a recording / reproducing apparatus and a recording medium changer. The same parts as those in FIG.

  The recording / reproducing apparatus 190 is obtained by adding a wireless communication unit 170 to the recording / reproducing apparatus 1 shown in FIG. The wireless communication means 170 is capable of local connection such as a wireless LAN.

  The recording medium changer 171 includes a wireless communication unit 172 that can communicate with the wireless communication unit 170, connectors 176 to 178 that connect to the recording media 180a, 180b, and 180c, and a switch 175 that selects one of the connectors 172 to 178. A recording medium RW unit 174 for reading and writing the recorded recording medium data. The control means 173 controls each component of the recording medium changer 171 and exchanges data. For example, the control unit 174 transmits the content requested from the recording / playback apparatus 190 via the wireless communication unit 172.

  According to the recording medium changer 171, it is possible to browse, move, and duplicate contents in the recording medium without inserting the recording medium into the recording / reproducing apparatus 190. Note that although FIG. 17 illustrates the case where three recording media are connected, the number of connected recording media can be increased by increasing the number of connectors. Furthermore, it is possible to increase the number of connectable recording media by adding an expansion unit as an expansion unit including only a switch unit and a connector unit.
