BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of supplying a part of use license information of supplied moving image data by using a computer network to give a presentation such as a display in a form desired by a user. The present invention relates to a license information supply system and a presentation method for a moving image presentation that can be provided.

[0002] A moving image presentation apparatus which enables a user to apply for a license for a part of the supplied moving image data using a computer network and give a presentation such as display to a user in a desired form. The present invention relates to a moving image presentation method.

[0003] Further, the present invention relates to a moving image recording medium which enables a user to apply for a license for a part of the recorded moving image data using a computer network and to give a presentation such as display to a user in a desired form. .

[0004]

2. Description of the Related Art In recent years, opportunities to use digital moving images in computers and communication terminals have increased, and various contents have been created. In particular, moving image data using MPEG2 (ISO13818) compression encoding technology will be generally sold in accordance with the standard called DVD, and the opportunity to use digital moving images in personal computers, communication terminals, and home playback devices Has increased.

[0005] In addition, advances in LSI process technology and computer development technology have made it possible to perform high-speed arithmetic processing.
It is now possible to decode and play back MPEG2 video compression encoded data recorded in D.

As a result, an environment in which many people can easily handle digital moving images is being prepared.

[0007] In a diversifying social situation, moving images have attracted attention as means of expression. Conventionally, there has been an increasing need to introduce moving images into presentations using personal computers, communication terminals, and the like, which mainly focus on text, drawing, and still images.

However, presentations using moving images still have problems. One is the issue of copyright. The copyright of digital moving image data sold and supplied on DVDs and the like belongs to the creator (creator), and cannot be used for editing, use, or expression without permission of others.

Another problem is the cost required for producing digital moving image data. Although it became possible to handle digital moving images easily with a personal computer, etc., the actual production itself used the traditional shooting method, and only labor saving was made in the creation and distribution of media, In order to actually obtain moving image data that can withstand a presentation as an expression means, enormous cost and labor are required. A user who makes a presentation using a large amount of moving image data must create data using moving image data distributed to society.

[0010] For example, in the case of still images, CD-ROMs on which about 100 pieces of still image data are recorded are generally sold, and most of these are processed, edited, and printed by the seller. All distributions are allowed with restrictions.
If such a mode is performed using moving image data, the amount of money required to process data for one or two hours recorded on a DVD is enormous, and from a distribution viewpoint, It cannot be valid.

Further, the problem of the size of image data is also important. Currently, high-speed networks are gradually being developed, but the delivery of moving images requires a faster infrastructure than other media. In addition, high quality is required for resolution and image quality of images used in presentations and the like, and these requirements are increasing with the times.

[0012] For this reason, there is a current situation that the speeding up of the network cannot keep up with the required image quality.
As a result, the distribution of high-quality images actually used in presentations and the like must rely on recording media such as optical disks and tapes.

[0013]

In the conventional moving image data providing form, the user is not in a state where editing is freely possible, and the cost required when possible is low. It is very expensive due to the cost of creation. As a result, even if the moving image required for editing for a presentation or the like is only a small part, the user has to pay for the entire provided media, which is a large cost. There was a problem.

[0014] On the other hand, there is a problem that the cost is extremely enormous if the data produced by the user is individually produced for the supplier.

d) buttons for designating various functions such as a bookmarker function (31e), 32 is a license information issue request button, 33 is a presentation form selection box, and 34 is a display screen. The user selects a predetermined time position by clicking these buttons with a mouse or the like.

Returning to FIG. 2, reference numeral 24 denotes an image display means comprising, for example, an LCD; 25, an image data decoding means;
Is a network communication means, 27 is a control means, 28 is a memory used by the control means, and 29 is a recording means for the terminal 11 to record editing information.

Here, in order to select a moving image to be used for a presentation using the terminal 11, a scene to be used for a presentation is selected from existing moving image data. First, the necessary information includes time information such as a start time and an end time. In addition, information on a presentation form such as text and drawing insertion is also necessary when a moving image is to be edited or an image is to be imposed.

FIG. 4 shows a procedure for selecting a moving image to be used in a presentation using the terminal 11.

In FIG. 4, in step S41, it is determined whether or not there is an instruction from the user to reproduce and display a moving image used in a presentation. Specifically, the user first inputs a moving image display command from the instruction input unit 23, and if the user does not want to supply a moving image used in the presentation, the process proceeds to step S45 to continue the current operation, On the other hand, if desired, after reproducing and displaying the moving image used for the presentation, the process proceeds to step S42. When reproducing and displaying the moving image, the control unit 27
An instruction to read the designated data from the recording medium 21 is given to the recording medium reading means 22, and an instruction to decode the data output from the recording medium reading means 22 is given to the image data decoding means 25. Is performed on the display means 24. As a result, the code data read from the recording medium 21 is decoded, and the image is output from the display unit 24.

The instruction input means 23 has functions such as a special reproduction command such as fast-forward or rewind, and a bookmark function for determining a position.

In the case of the fast feeding, the control means 27 controls the recording medium 2
1 to the recording medium reading means 22 and instruct the image data decoding means 25 to perform high-speed reproduction or thinning-out reproduction. Thus, high-speed or thinned-out moving image data is transferred to the display means 24, and the display is performed on the screen at a speed higher than that of normal reproduction.

In the case of rewinding, the control means 27 controls the recording medium 2
1 instructs the recording medium reading means 22 to perform reverse reading. However, continuous reproduction cannot be performed by simple reverse reading, so that, for example, in the case of an optical disc or the like, an operation of reading data of an amount that can be reproduced as an image and returning to a track is repeated. Also, if the moving image data is MPEG (ISO11
(1722 / ISO13818), since the recording order and the display order are different, the processing is implemented by adding a process of exchanging data so that the image data decoding means 25 can decode on the memory. Is done. Subsequent decoding and display operations are the same as those in the case of the fast-forwarding, and thus will not be described.

In step S42, the user desires to use the moving image used in the presentation in the range,
That is, the time information of the start time and the end time is stored in the bookmark function (31).
The time information (data position on the recording medium 21) is specified by the control unit 2 by specifying using the specification button of e).
7 are temporarily stored. In the end, for example, the positions of two bookmarks are memorized, and the relationship
(Position, interval, etc.) are required for presentation license information. At the time of this selection work, a temporal position of the image is selected from the reproduced images, and a presentation form such as reduction, enlargement, cutout, and effect is selected. The selection of the temporal position information of the image and the selection of the presentation mode are not always performed in this order. If the position information of the two bookmarks is not input in step S42, the process proceeds to step S46 to continue the reproduction operation.

In step S43, if the moving image used in the presentation is displayed / reproduced, step S4
Then, if the moving image is not displayed / reproduced, the process proceeds to step S47 to continue the current operation.

In step S44, the time information designated by the user in step S42 is stored in the memory 28, and the information necessary for the presentation including the time information is sent via the computer network A to the moving picture presentation license information supply server. 12 is sent.

Using the license information thus obtained, the terminal 11 can present a moving image in a desired form.

FIG. 5 shows a procedure in which the presentation license information supply server 12 issues license information based on an instruction from the terminal 11.

In FIG. 5, in step S51, the presentation license information supply server 12 determines whether or not there has been any instruction from the user terminal 11, and if there is no instruction, the flow proceeds to step S55 to proceed to the current operation. If there is any instruction, the process proceeds to step S52.

In step S52, the presentation license information supply server 12 sends the user's terminal 11
It is determined whether or not there has been a license information request. Specifically, the bookmark information and the presentation form are stored in the memory 28 by the control means 27, and the user selects a license information issuance request from the instruction input means 23 (the license information issuance button 32 is pressed in FIG. 3). In this case, the control means 27 sends the bookmark data of the two start positions and the end position and the presentation form stored in the memory 28 to the presentation license information supply server 12 so as to transmit them to the presentation license information supply server 12.
To transfer the data to.

On the other hand, if there is no such license information request, the flow advances to step S56 to continue the designated reproduction operation.
On the other hand, if there is a license information request, the process proceeds to step S53.

In step S53, it is determined whether or not there is information necessary for the presentation including time information (see step S44) from the user terminal 11, and if there is no such information, or if there is any If it is missing, it is determined that an error has occurred, and the process proceeds to step S57.
Proceed to 54.

In step S54, the moving image presentation license information supply server 12 creates time information and license information according to the presentation form based on the information obtained from the terminal 11,
Send to At this time, the charging information together with the issued license information is transmitted to the terminal 11 via the computer network A.

It is recorded in the recording means 29. The information (program) of the entire presentation is also recorded in the recording means 29. At this time, the presentation program is stored internally if the level is storable by the control means 27, and is stored in the memory 28 if the capacity is exceeded. In the case of a capacity that cannot be stored here as well, the storage is sequentially updated in size units executable from the second recording medium,
Will be executed.

Finally, FIG. 6 shows a procedure for executing a presentation program in the terminal 11 based on the license information issued from the presentation license information supply server 12.

In FIG. 6, in step S61, the playback button (31a) is pressed, and it is determined whether or not there is a request to output a moving image for presentation. If there is no request, the flow proceeds to step S64 to proceed to step S64. Continue the operation of
On the other hand, if there is any instruction, the process proceeds to step S62.

In step S62, the control means 27 searches the recording means 29 for the presence or absence of license information. If there is no license information, the flow proceeds to step S65. If there is license information, the flow proceeds to step S63. .

In step S63, the control means 27 operates in accordance with the presentation program read from the internal register, the memory 28, and the second recording medium, and outputs on the screen and other output devices not shown (such as audio output).
To give presentations sequentially. Then, at the stage of displaying the edited moving image, the control unit 27 searches the license information from the recording unit 29, and when the license information of the moving image is found, the control unit 27.
Instructs the recording medium reading means 22 to read the encoded data of the corresponding image from the recording medium 21, and instructs the image data decoding means 25 to decode and reproduce the read data. As a result, the decoded image data is output as a presentation on the screen by the display means 24, and the moving image is displayed according to the license information and the presentation form.

The simplest example of such a presentation terminal is a personal computer, on which the moving image presentation software is executed.

Since the amount of encoded video data is enormous, it is desirable that such video data be sold in advance at low cost or distributed free of charge. The simplest examples are presentation software and
Some moving image data examples are to be bundled using media such as CD-ROM and DVD-ROM. And in the media,
Alternatively, by exchanging with a bundled medium, a moving image is selected, and license information of a region of the moving image used for making a presentation is requested from a server on the network. The server sends the license information at that time,
Alternatively, an actual presentation is realized by supplying the information by e-mail or the like and incorporating it into a presentation file.

A user who intends to give a moving image presentation by such a method can reduce a necessary communication amount and a copyright fee, and a provider can easily protect the copyright.
