In the present embodiment, the signal recording / reproducing apparatus 101 is a PDA (Personal Digital Assistants), and the recording medium 102 is a memory card (an SD card (registered trademark) in the embodiment).
[0017]
When content is input from the external device 190, the recording / reproducing unit 106 transfers the content to the recording medium 102. The content written by the recording / reproducing unit 106 to the recording medium 102 is digitized data such as music, images, movies, texts, and the like. For example, when the external device 190 is a video camera or a video tuner, MPEG4 format moving image content is input to the recording / reproducing unit 106. When the external device 190 is a digital still camera, the content of a still image in the JPEG format is input to the recording / reproducing unit 106.
[0018]
[Description of content data table]
The memory 105 stores a content data table. FIG. 2 is a diagram illustrating an example of a content data table according to the embodiment of the present invention. The content data table is a data table in which information of the content written on the recording medium 102 by the signal recording / reproducing apparatus 101 is written. Reference numerals 201, 202, and 203 denote recording medium identification numbers, 211, 212, and 213 denote serial numbers of recording media used in the signal recording / reproducing apparatus 101, and 221, 222, and 223 denote recording medium identification images. Reference numerals 251 to 259 denote content information.
[0019]
The recording medium identification number is identification information unique to the recording medium 102. In the case of the SD card, a unique ID number is recorded as data inside and is displayed on the front surface so that the user can identify it. Therefore, in the embodiment, the ID number is used as a recording medium identification number. The recording medium identification number may be a value specified by the user.
[0020]
The recording medium identification image is an image representing the appearance of the recording medium 102 for the user to visually identify the recording medium 102. A photograph of the whole or a part of the recording medium 102 such as a photograph of a sticker attached to the surface of the recording medium 102, an enlarged photograph of a serial number, a photograph of a symbol written on the surface of the recording medium 102 by a user, and the like. It can be used as an identification image. Alternatively, an image previously stored in the memory 105 may be used. The file names of the data obtained by iconifying such photographs and images are used for processing inside the CPU 104.
[0021]
The content information is information about the content. More specifically, the information includes the title, creation date, type (image, music, text, etc.), recording location, size (time, file size, etc.), format, and the like of the content. The content information may be created automatically by the CPU 104 or manually entered by the user.
[0022]
The content data table is a correspondence table for associating a content with a recording medium on which the content is recorded using a recording medium identification number and a recording medium identification image. Therefore, the content data table includes at least a recording medium identification number, a recording medium identification image, and content information.
[0023]
[Writing content to recording medium]
FIG. 3 is a flowchart when writing content to a recording medium according to the embodiment of the present invention. In step 301, content is input from the external device 190 to the recording / reproducing unit 106. When the user loads the recording medium 102 into the signal recording / reproducing apparatus 101 (step 302), the CPU 104 reads the recording medium identification number from the recording medium 102 (step 303). In step 304, a screen prompting the user to determine whether to read the recording medium identification image is displayed on the display unit 103. If the user specifies not to read the recording medium identification image, the CPU 104 reads the predetermined recording medium identification image from the memory 105 in step 310, and proceeds to step 306. If the user specifies to read the recording medium identification image, the recording medium identification image is read in step 305, and the process proceeds to step 306. In step 306, the contents of the recording / reproducing unit 106 are written to the recording medium 102.
[0024]
In step 307, content information is created. The CPU 104 outputs the default value to the display unit 103, and the user corrects it as appropriate. In step 308, the CPU 104 determines whether or not the recording medium 102 on which the writing has been performed in step 306 is included in the content data table, that is, whether or not the recording medium 102 has been used. If it has already been used, the content information is written in the corresponding area of the content data table (step 309). If not already used, the recording medium identification number, the recording medium identification image, and the content information are written in the content data table (step 311), and the process ends.
[0025]
[Reading content from recording media]
FIG. 4 is a flowchart for reading content from a recording medium according to the embodiment of the present invention. When a user performs an operation for reproducing content on the signal recording / reproducing apparatus 101, the CPU 104 reads the content data table from the memory 105 and displays the content data table on the display unit 103. FIG. 5 is a diagram illustrating an example of a display on the display unit 103 of the signal recording / reproducing apparatus 101 according to the embodiment of the present invention. A list of content titles is displayed.
[0026]
At step 402, the user selects content in the following manner. In FIG. 5, when “details” is selected for one content (content 1 in the embodiment), the content information (content title, recording date and time, type, recording medium identification number of the recorded medium, recording The location and the recording medium identification image of the recorded medium) are displayed on the display unit 103 as shown in FIG.
When "Sort" is selected in FIG. 5, the order of displaying the titles of the contents in FIG. 5 can be changed. For example, the order of the content titles is ABC order / Iowa order, or the type order. In FIG. 5, “previous page” and “next page” are used to display the content that is continued or before the list of contents cannot be displayed on the display unit 103. The user selects the content to be reproduced from the screen display of FIGS.
[0027]
When the content to be reproduced is determined, and the user selects “reproduce” for one content in FIG. The CPU 104 displays the recording medium identification number and the recording medium identification image of the recording medium 102 including the selected content on the display unit 103. FIG. 7 shows an example of the display at this time. The display unit 103 displays not only the recording medium identification number of the storage medium but also a photograph (recording medium identification image). Therefore, the user can easily select the storage medium from the appearance of the recording medium. The user's labor can be greatly reduced as compared with a case where one recording medium is searched for from a plurality of recording media based only on the recording medium identification number.
[0028]
When the user selects a recording medium and loads it into the signal recording / reproducing apparatus 101 (step 404), the CPU 104 compares the recording medium identification number of the loaded recording medium with the recording medium identification number of the specified recording medium. It is determined whether or not the recording medium is correct (step 405). If the loaded recording medium is incorrect, the user is requested to load the correct recording medium (step 407). Specifically, the display unit 103 displays a message “The recording medium is different. Insert the displayed card.”, A recording medium identification number, and a recording medium identification image on the display unit 103. Return to step 404. If the loaded recording medium is correct, the content is read from the recording medium 102 and reproduced (step 406). The process ends.
[0029]
The flowchart for reading the content from the recording medium and the display on the display unit 103 are not limited to FIGS. FIG. 8 is a diagram showing an example of the display on the display unit 103 in step 401 of FIG. In FIG. 5, only the title of the content is displayed, but in FIG. 8, the serial number of the recording medium, the recording medium identification number, and the recording medium identification image are also displayed. In this case, step 403 in FIG. 4 may be omitted.
[0030]
In the embodiment, since the content data table is stored in the memory 105 in the signal recording / reproducing device 101, only the signal recording / reproducing device 101 that has recorded the content on the recording medium 102 can browse the content information of the content. When two recording media can be loaded into the signal recording / reproducing apparatus 101 at one time, the content data table may be stored in one of the recording media and used as the memory 105. If the content data table is also stored in the recording medium 102, the content information can be browsed by an arbitrary signal recording / reproducing device 101.
[0031]
