Description

  The present invention relates to an HTML content visualization apparatus capable of converting HTML content into video and an operation method thereof.

  In recent years, with the widespread use of digital television, content other than video has been frequently viewed on television. For example, HTML contents widely released on the Internet can be browsed with an HTML browser installed in a digital television.

  The HTML content is a generic name for content composed of an HTML file described in HyperText Markup Language, or an HTML file and a file such as an image associated with the HTML file.

  When viewing HTML content on a digital television, many use a remote controller (remote controller) attached to the television, but the HTML content viewing operation is originally premised on an operation using a mouse or keyboard. For example, there were the following problems.

  1) In the operation method in which the cursor moves to the linkable position each time the direction button is pressed instead of direct designation operation with the mouse, the remote control is repeated many times in order to view all the contents in the site having a lot of link information. It was necessary to press the button. This is particularly noticeable in HTML contents that are often vertically long.

  2) Even with browsers and remote controls that allow the cursor position to be freely specified like a mouse, it is necessary to keep pressing the button when moving the cursor to the target position of the content, and a finer link position is specified. It was difficult to make fine adjustments.

  3) A method of moving by assigning number tags to the link position in a certain order and inputting the number of the target link with the remote control. This is a number input (about 3 digits) when specifying the target position of the content. The number of button presses can be reduced because it is only a numeric string), but there is a problem that the original content screen is difficult to see due to the number tag attached to the link.

  There are others that use external devices such as a personal computer (PC) keyboard, but the connection is troublesome. All of them had advantages and disadvantages, and there was a need for a method that could be easily operated with a remote control.

  Further, as described in Non-Patent Document 1 below, there is an attempt to convert HTML content into a moving image style, but HTML content is handled as HTML content, and this cannot be displayed on a BML browser.

An HTML content imaging apparatus comprising an imaging unit for converting an image into an image is used as a solution means.

  For example, if the number of the images is smaller than a predetermined number, the HTML content visualization apparatus duplicates the images so that the number of images after duplication is larger than the predetermined number. .

  For example, the HTML content visualization apparatus obtains the number of images already obtained at a timing in the middle of obtaining the image, and writes the number of images in a file provided in advance.

  For example, the number of images already obtained at the timing of obtaining the image is obtained, the number is divided by a predetermined frame rate of the video, and the result of the division is written in a file provided in advance. .

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[First Embodiment]
FIG. 1 is a configuration diagram of a communication system including an HTML content visualization apparatus according to the first embodiment.

  The HTML content visualization server 1 (HTML content visualization device) acquires HTML content from the web server 2 via the network 3, converts it into video (here, BML content), and displays the content via the network 4. 5 to the server.

  Each of the networks 3 and 4 is the Internet or a closed network. The display device 5 is a device capable of displaying (reproducing) BML content and includes a BML browser.

  The remote controller 51 is used for the operation of the display device 5 and communicates with the display device 5 by infrared rays or wireless.

  The HTML content visualization server 1 includes a communication unit 11 that communicates with the networks 3 and 4, an imaging unit 12 that converts HTML content into an image at multiple timings while scrolling HTML content, and converts the obtained plurality of images into video. And an imaging unit 13 that performs the processing.

  FIG. 2 is a diagram comparing the size of HTML content with the display area of the display device 5.

  The number of pixels in the display area is H × W, that is, the length in the vertical direction (referred to as height) is H, and the length in the horizontal direction (referred to as width) is W. When the HTML content is displayed, the total number of pixels is H ′ × W ′, that is, the vertical length (height) is H ′ (> H), and the horizontal length (width) is W ′ (> W). ). In the first embodiment, an image including a height H ′ and a width W in the HTML content viewed from the top to the bottom is used as a chapter, and an image including one or more chapters is generated.

  The HTML content visualization server 1 stores height H, H ′, width W, W ′ in advance, and reads and uses them appropriately. In addition, the HTML content visualization server 1 stores in advance constants Δm and Δn used in the operation, and appropriately reads and uses them. Also, the HTML content visualization server 1 has areas of coordinates (m, n), variables i, idx, and images (i) used in its operation, and stores the coordinates, variables, and images in the corresponding areas, as appropriate. It is designed to read. Also, the HTML content visualization server 1 has a chapter file used in its operation.

  For example, when the user operates the remote controller 51 and inputs a desired address to the display device 5, the display device 5 transmits the address (URL) to the HTML content visualization server 1.

  The communication unit 11 receives the address, accesses the web server 2 having the corresponding HTML content, and acquires the HTML content via the network 3.

  FIG. 3 is a flowchart showing the operation of the HTML content visualization server 1 after the HTML content is acquired in the first embodiment.

  First, the imaging unit 12 analyzes the HTML content and obtains the height H ′ and the width W ′ (S1).

  Next, the imaging unit 12 initializes the coordinates (m, n) to (0, 0), the variable i to 0, and the variable idx to 0 (S3).

  Next, the imaging unit 12 converts an area surrounded by coordinates (m, n), (m + H, n), (m, n + W), and (m + H, n + W) into an image, that is, an image (i) in the HTML content. Conversion is performed (S5). For example, an HTML rendering engine is used for conversion to an image. The format of the image is, for example, JPEG (Jay Peg, Joint Photographic Groups), BMP (Bitmap), PNG (Ping, Portable Network Graphics), or the like.

  Next, the imaging unit 12 determines whether or not the height H is greater than or equal to a value (H ′ + Δm) (S7). If not (S7: NO), Δm is set to the coordinate m, and 1 is set to the variable i. Add (S9) and return to step S5.

  On the other hand, if it is determined YES in step S7, the imaging unit 12 corresponds the character string “chapter” and the variable idx as an identifier indicating a chapter, and the variable i, that is, the number of generated images, as a chapter switching index. Then, for example, “chapter 1-929” is written in the chapter file (S11).

  The imaging unit 12 divides the variable i by the frame rate (for example, 29.97 frames / second), converts the calculation result, that is, the end time of the chapter in terms of seconds into the format of hours, minutes, and seconds, A character string “chapter” and a variable idx are used as an identifier indicating a chapter, and values in the form of hours, minutes, and seconds are associated with each other as a chapter switching index. The chapter file may be written (S11).

  Next, the imaging unit 12 adds 1 to the variable idx (S13).

  Next, the imaging unit 12 determines whether or not the width W is greater than or equal to a value (W ′ + Δn) (S15). If not (S15: NO), Δn is added to the coordinate n and 1 is added to the variable i. Then, the coordinate m is initialized to 0 (S17), and the process returns to step S5.

  On the other hand, if it is determined YES in step S15, the imaging unit 13 converts the image (0) to the image (i) into a video that can be reproduced in the order of this image (S19). Visualization can be performed by software such as ffmpeg, for example. In ffmpeg, if a plurality of images and a frame rate are given, the plurality of images can be converted into video of the frame rate.

  Note that the conversion from an image to a video can be performed using software such as ffmpeg. In addition to normal playback, the video may be slow playback, fast forward, pause, etc.

  Next, the communication unit 11 transmits this video and chapter file to the display device 5 (S21), and the process ends.

For example, if the index is the number of pixels,
chapter 1-929
chapter2-1858,
chapter 3-2787,
(Hereafter omitted)
And so on.

Or the chapter file, for example, if the index is the chapter end time,
chapter 1-00: 00: 31
chapter2-00: 01: 02,
chapter 3-00: 01: 33,
(Hereafter omitted)
And so on.

  The display device 5 receives the transmitted video and plays it with the BML browser. The video is paused, fast forwarded, rewinded, and paused as appropriate. The chapter time in the video becomes longer as the height H ′ is higher.

  Normal video playback, slow playback, fast forward, and rewind correspond to vertical scrolling of HTML content. The smaller the constant Δm, the slower the scroll speed.

  In addition, the display device 5 performs chapter switching based on the index written in the chapter file, thereby obtaining the same effect as the horizontal scrolling.

  If the constant Δn <W, there is an overlapping area between chapters, and the smaller the constant Δn, the smoother the horizontal scrolling becomes. For example, when the HTML content is a map, the positional relationship in the horizontal direction can be confirmed, which is preferable.

  On the other hand, if constant Δn = W, there will be no overlap between chapters. That is, it is possible to provide a user interface in which the screen is switched by chapter feeding.

  The constants Δm and Δn are previously stored in the HTML content imaging server 1, but may be set from the outside.

[Second Embodiment]
Next, a second embodiment will be described. The second embodiment is different from the first embodiment in that the length of the video time is equal to or longer than a desired length. The configuration of the communication system according to the second embodiment is the same as that of the first embodiment, and the same components are denoted by the same reference numerals and redundant description is omitted.

  In the second embodiment, the HTML content visualization server 1 stores in advance a value TH equal to the number of images corresponding to the desired video time length. When 29.97 images are used for 1-second video, that is, when the frame rate is 29.97 and the length of time of the video is at least 30 seconds, the value TH is set as the HTML content imaging server. 1 stores a value “899 (= 30 × 29.97)” in advance.

  When the HTML content is acquired, the HTML content visualization server 1 executes steps S1 to S15 in FIG. 3, and if NO is determined in step S15, Δn is added to the coordinate n and 1 is added to the variable i. The coordinate n is initialized to 0 (S17), and the process returns to step S5.

  FIG. 4 is a flowchart showing the operation of the HTML content imaging server 1 after it is determined YES in step S15 of FIG.

  If it is determined YES in step S15 of FIG. 3, the imaging unit 12 first determines whether the variable i is less than the value TH (T1).

  If not (T1: NO), the imaging unit 12 converts the image (0) to the image (i) into a video that can be reproduced in the order of this image (T3).

  If the variable i is less than the value TH (T1: YES), the imaging unit 12 calculates the value TH / variable i and selects the smallest integer value N that is equal to or greater than this value (T5).

  Next, the imaging unit 12 duplicates the images so that N images from the image (0) to the image (i) are obtained as a result (T7).

  Next, the imaging unit 12 rewrites the index written in the chapter file to an index multiplied by N (T9).

  Next, the imaging unit 13 converts the N images (0) to N images (i) into videos that are reproduced in the order of these images (T11).

  Next, after steps T3 and T11, the communication unit 11 transmits the video and chapter file converted by either method to the display device 5 (T13), and the processing is completed.

  The display device 5 receives and reproduces the transmitted video. The video is paused, fast forwarded, rewinded, and paused as appropriate. The length of video time is, for example, 30 seconds or more, which is suitable for visualization of HTML content that needs to be viewed for a long time. In addition, by duplicating the image and lengthening the video time, the same effect can be obtained as when the scrolling speed is slowed down.

  Note that the value TH that determines the length of time of the video is previously stored in the HTML content video server 1, but may be set from the outside.

  As described above, according to the content visualization device according to each embodiment, HTML content can be converted into video. Therefore, if the display device can display video, the content of the HTML content can be obtained without having an HTML browser. Can be confirmed. Since the video browsing operation is simpler than the HTML content browsing operation, a reduction in the number of operations can be expected. In addition, the contents of the HTML content can be confirmed while performing slow playback, fast-forwarding, pause, etc. peculiar to the video. In addition, since the chapter file is generated, it is possible to enjoy the convenience of operations unique to the video such as chapter sending.

  A computer program for causing the server 1, that is, the HTML content imaging apparatus, to execute the operation method of the HTML content imaging server 1 is readable by a computer such as a semiconductor memory, a magnetic disk, an optical disk, a magneto-optical disk, and a magnetic tape. It can be recorded on a recording medium and can be widely distributed by being transmitted through a communication network such as the Internet.
