DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, examples specifically showing the best mode for carrying out the present invention will be described with reference to the drawings.
[0015]
"Example"
A signal recording / reproducing apparatus and a signal recording / reproducing method according to an embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a diagram showing a configuration of a signal recording / reproducing apparatus according to an embodiment of the present invention. 101 is a signal recording / reproducing apparatus, and 102 is a removable recording medium. Reference numeral 190 denotes an external device. The signal recording / reproducing apparatus 101 includes a display unit 103, a CPU 104, a memory 105, and a recording / reproducing unit 106.
[0016]
The signal recording / reproducing apparatus 101 has a slot into which the recording medium 102 is inserted. In this embodiment, the signal recording / reproducing apparatus 101 is a PDA (Personal Digital Assistant), and the recording medium 102 is a memory card (in the embodiment, an SD card (registered trademark)).
[0017]
When content is input from the external device 190, the recording / playback unit 106 transfers the content to the recording medium 102. The content that the recording / playback unit 106 writes to the recording medium 102 is digitized data such as music, images, movies, and texts. For example, when the external device 190 is a video camera or a video tuner, moving picture content in the MPEG4 format is input to the recording / playback unit 106. When the external device 190 is a digital still camera, the content of a still image in JPEG format is input to the recording / playback 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 the content data table according to the embodiment of this invention. The content data table is a data table in which information on the content written on the recording medium 102 by the signal recording / playback apparatus 101 is written. Reference numerals 201, 202, and 203 denote recording medium identification numbers, 211, 212, and 213, reference numbers of recording media used in the signal recording / reproducing apparatus 101, and reference numerals 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 an SD card, a unique ID number is recorded therein as data, and is displayed on the surface so that the user can identify it. In the embodiment, the ID number is used as a recording medium identification number. The recording medium identification number may be a value designated 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, or a photograph of a symbol marked on the surface of the recording medium 102 by a user. It can be used as an identification image. Alternatively, an image stored in advance in the memory 105 may be used. The file name of data in which such a photograph and image are converted into an icon is used for processing inside the CPU 104.
[0021]
The content information is information related to the content. Specifically, the content title, creation date, type (image, music, text, etc.), recording location, size (time, file size, etc.), format, etc. The content information may be created automatically by the CPU 104 or manually input by the user.
[0022]
The content data table is a correspondence table for associating a content and 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]
[Write content to recording media]
FIG. 3 is a flowchart when the content of the embodiment of the present invention is written to the recording medium. In step 301, content is input from the external device 190 to the recording / playback 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 that prompts the user to determine whether or not to read the recording medium identification image is displayed on the display unit 103. When the user designates not to read the recording medium identification image, the CPU 104 reads a predetermined recording medium identification image from the memory 105 in step 310 and proceeds to step 306. If the user designates reading 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 content of the recording / playback unit 106 is written to the recording medium 102.
[0024]
In step 307, content information is created. CPU104 outputs a default value to the display part 103, and a user corrects it suitably. In step 308, the CPU 104 determines whether or not the recording medium 102 written in step 306 is included in the content data table, that is, whether or not the recording medium 102 is already used. If already used, the content information is written in the corresponding area of the content data table (step 309). If it is 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 when reading the content of the embodiment of the present invention from the recording medium. When the user performs an operation for requesting content reproduction on the signal recording / reproducing apparatus 101, the CPU 104 reads the content data table from the memory 105 and displays it on the display unit 103. FIG. 5 is a diagram showing an example of 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]
In 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), content information of the content (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 in which the titles of the contents are displayed in FIG. 5 can be changed. For example, the order of content titles is ABC / Iweo or type. In FIG. 5, “Previous page” and “Next page” are used to display the contents that are displayed following or before the list of contents that cannot be displayed on the display unit 103. The user selects content to be reproduced from the screen displays of FIGS.
[0027]
When the content to be played back is determined and the user selects “playback” 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 is a diagram showing 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. Compared to searching for a single recording medium from a plurality of recording media based only on the recording medium identification number, the user's labor can be greatly reduced.
[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 designated recording medium, It is determined whether or not the recording medium is correct (step 405). If the loaded recording medium is not correct, the user is requested to load the correct recording medium (step 407). Specifically, a message “Recording medium is different. Insert the displayed card.”, A recording medium identification number, and a recording medium identification image are displayed 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). End the process.
[0029]
The flowchart when 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 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 reference 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, the content information of the content can be browsed only by the signal recording / reproducing device 101 that has recorded the content on the recording medium 102. 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 recording medium 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 apparatus 101.
[0031]
