FIG. 2 is a schematic diagram illustrating an example of a hardware configuration in the moving image reproducing apparatus according to the present embodiment. The operation of each hardware component in the moving image thumbnail information acquisition process and the moving image thumbnail reproduction process will be described with reference to FIG. As shown in this figure, this apparatus includes an “interface” 0201 and a “storage device (or storage medium)” 0202 that are moving image information holding units, a “CPU” 0203 that is a moving image thumbnail information acquisition unit and a reproduction unit, and “main”. A “memory” 0204 and a “display” 0205 as a display unit. These are connected to each other via a data communication path such as a “system bus” 0206 to perform transmission / reception and processing of information.
The storage device stores various programs executed by the CPU, moving image information, and the like. The main memory reads a program stored in the storage device for execution, and simultaneously provides a work area that is a work area for the program. A plurality of memory addresses are assigned to the main memory and the storage device, respectively, and a program executed by the CPU performs processing by exchanging data with each other by specifying and accessing the memory address. It is possible.
The interface is, for example, a recording medium such as a DVD or CD (regardless of whether it is read-only or rewritable), a DVD drive 0207, a CD drive 0208, or an external storage device such as an HDD. Is provided with a function of acquiring moving image information from the storage device and storing the acquired moving image information in a storage device or a dedicated temporary storage memory.

Specifically, for example, the interface acquires a command “display thumbnails of the moving image information and perform fast-forward playback”, for example, by pressing a remote control button by the user. Then, first, the moving image information is stored in a memory address α of a storage device (including an external storage device such as an HDD; the same applies hereinafter). Next, the moving image thumbnail information acquired from the moving image information based on the moving image thumbnail information acquisition program described later is stored in the memory address β of the storage device. Then, the moving image thumbnail displayed based on the moving image thumbnail information is fast-forwarded and reproduced based on the reproduction program described later.

  FIG. 3 is a diagram illustrating an example of a moving image thumbnail information acquisition program in the moving image reproducing apparatus according to the present embodiment. The program of this example (1) acquires the identification information of the moving image information and stores it in the memory address X (line number 001 in the figure), (2) the program is the moving image information related to the identification information stored in the memory address X Is read and stored in the memory address α (002), (3) the condition for reproducing the moving image thumbnail related to the moving image information is acquired and stored in the memory address Y (003), (4) stored in the memory address Y In this program, a dot that matches a certain condition is acquired as moving image thumbnail information and stored in the memory address β (004). Note that the acquisition of the condition in 003 is performed based on a table in which, for example, the number of moving image dots and a condition to be selected when reproducing a moving image thumbnail are associated with each other.

  FIG. 4 is a conceptual diagram for explaining an example of a configuration related to acquisition of a condition based on the association table. FIG. 4A shows an example of such a table, in which the dots of the moving image to be selected when reproducing the moving image thumbnail are indicated by coordinates corresponding to the number of moving image dots in the left column. As shown in FIG. 4B, the coordinates are expressed based on the column assigned a serial number from the left and the row from the top. Therefore, in FIG. 4A, when the number of dots in the moving image is 1024 × 768, (1, 1) (showing the first row and first row), (1, 31) and so on every 30 dots. The condition to be selected is shown. As a result, the moving image thumbnails in the lower column from the moving images in the upper column in FIG. 4B are obtained from the dots obtained by such selection.

  Next, using FIG. 2 again, a configuration related to acquisition of moving image thumbnail information based on the above-described moving image thumbnail information acquisition program will be described. First, a moving image thumbnail information acquisition program as a moving image thumbnail information acquisition unit is expanded in the work area of the main memory, and acquires moving image information at the memory address α of the storage device, which is moving image information identified by the identification information acquired by the above processing. Then, an instruction to store in the memory address 1 of the main memory is sent. Then, in accordance with the instruction, the CPU reads the moving image information stored at the memory address α from the storage device and stores it at the memory address 1 of the main memory. Next, from the moving image information stored in the memory address 1 of the main memory, the CPU acquires moving image thumbnail information in accordance with the above conditions and stores it in the memory address 2 of the main memory. Further, the moving image thumbnail information may be stored at the memory address β of the storage device.

  FIG. 5 is a diagram illustrating an example of a reproduction program in the moving image reproduction apparatus according to the present embodiment. The program of this example acquires (1) identification information of moving image thumbnail information and stores it in the memory address X (line number 001 in the figure), (2) stores moving image thumbnail information identified by the identification information from the storage device. (002), (3) Generate a moving image thumbnail based on the moving image thumbnail information and store it in the memory address Z (003), (4) Reproduction method of the generated moving image thumbnail ( A signal input via the interface by a user's remote control operation or the like is acquired (004), and a video thumbnail to be played back is selected from the video thumbnails based on the acquired signal. (005), (5) play the video thumbnail on the display (00) ), It is a program of the. Note that the selection of the moving image thumbnail to be reproduced in 005 is performed based on, for example, a table in which the reproducing method indicated by the input signal is associated with the moving image thumbnail selected at the time of reproduction represented by a serial number.

  FIG. 6 is a conceptual diagram for explaining an example of a configuration related to selection of a moving image thumbnail based on the association table. FIG. 6A is an example of such a table, and the serial number of the moving image thumbnail to be reproduced is shown in the right column corresponding to the reproduction method such as normal, fast forward (double speed), etc. in the left column. . As shown in FIG. 6B, the serial numbers are assigned according to the scene order of the moving image thumbnails. Thus, for example, FIG. 6A shows that when fast-forward (double speed) playback is performed, a moving image thumbnail is played every other scene, such as 1, 3, 5, 7, 9, and so on. ing. Alternatively, in the case of fast forward (double speed), instead of playing back every other scene, all the scenes may be played back with the display time of each scene shortened. For example, in the case of normal reproduction, when the display time of one scene is 1/30 second, this is reproduced with a display of 1/60 second. In the case of slow playback, it can be considered that playback is performed in the same manner.

Next, referring again to FIG. 2, a configuration related to reproduction of a moving image thumbnail based on the above-described reproduction program will be described. First, a playback program as a playback unit is expanded in the work area of the main memory, and the moving image thumbnail information stored in the memory address β of the storage device, which is moving image thumbnail information identified by the identification information acquired by the above-described processing, is acquired. And sends an instruction to store in the memory address 2 of the main memory. Then, according to the command, the CPU reads the moving image thumbnail information stored at the memory address β from the storage device and stores it at the memory address 2 of the main memory. Next, when a reproduction signal is input through the interface by a user's remote control operation or the like, moving image thumbnail information corresponding to the input reproduction signal is selected from the moving image thumbnail information stored in the memory address 2. . For example, if the reproduction signal is a signal indicating that the reproduction signal is “fast forward (double speed)”, the CPU refers to the table as shown in FIG. Double-speed) ”is acquired. Then, the selected moving image thumbnail information is developed in the VRAM 0210, and the moving image thumbnail displayed based on the moving image thumbnail information is reproduced on the display.
The above example has been described with the case where the moving image thumbnail information acquisition unit acquires the moving image thumbnail information from the moving image information acquired from the recording medium such as a DVD by itself. The moving image information may include moving image thumbnail information in advance, and the moving image thumbnail information acquisition unit may be configured to acquire the moving image thumbnail information simply by copying the moving image information.
FIG. 7 is a conceptual diagram showing an example of a display state of reproduction on such a display. In the example shown in the figure, seven moving image thumbnails of titles 1 to 7 are displayed on the display. Also, immediately below each moving image thumbnail, the recording date and time of the moving image are displayed as reference information related to each. Also, although not shown in the figure, when there are many videos, only the video thumbnails related to some of the videos are displayed, and when displaying other video thumbnails, go to the next page or the previous page. You may make it display the icon for transfer to the lower right of a screen.
In addition, when a video thumbnail of “title 5”, for example, is selected from a plurality of video thumbnails on the display and click playback is performed, the title number corresponds to the number of the numeric buttons on the remote control. When the user presses the “5” button, the moving image thumbnail of “title 5” is selected. In FIG. 7, the state that the moving image thumbnail of “title 5” is selected in this way is indicated by the frame of the moving image thumbnail being displayed with a bold line.

<Process flow>
FIG. 8 is a diagram illustrating an example of the flow of processing in the moving image playback apparatus of the present embodiment. The flow of processing in the figure consists of the following steps.

  First, in the moving image information acquisition step S0801, the moving image reproducing apparatus acquires moving image information from a recording medium such as a DVD or CD, for example, by a DVD drive or CD drive, or from an external storage device such as an HDD. The acquired moving image information is temporarily stored in a storage device or a dedicated temporary storage memory.

  Next, in the moving image thumbnail information acquisition step S0802, the moving image playback apparatus acquires moving image thumbnail information from the moving image information. The moving image thumbnail information acquired here is also temporarily stored in a storage device or a dedicated temporary storage memory.

  Next, in step S0803 for reproducing a moving image thumbnail based on the moving image thumbnail information, the moving image reproducing device reproduces the moving image thumbnail. This reproduction includes trick reproduction.

  Furthermore, in the moving image thumbnail display step S0804, the moving image playback apparatus displays the moving image thumbnail on the display. In the display process, the moving image thumbnail that has been subjected to the reproduction process may be displayed, or the displayed thumbnail may be reproduced. That is, step S0804 may be processed after S0803 or may be processed before.
