DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to distribution of advertisements in video and music distribution over the Internet.

[0002]

2. Description of the Related Art Conventionally, when delivering video or music using the Internet, the user of the delivery pays a usage fee to the distributor. Since the distribution is performed through telecommunications, the payment of the fee is also performed by electronic commerce in which a user sends a credit card or prepaid card number to the distributor by telecommunication. Credit cards must be checked for unauthorized use at each transaction between the distributor and the credit card company using a communication line, and prepaid cards are issued and sold. It has to be complicated. When sending a credit card or prepaid card number from the user to the distributor using the Internet,
There is a risk that a third party intercepts and later, the intercepted person impersonates a legitimate user and receives unauthorized distribution. Images and music converted into digital data have very little deterioration in quality, and are easily copied. In particular, the widespread use of the Internet has resulted in a large number of illegal copies, and has unduly lost the opportunity to benefit video and music producers. When music is distributed on the Internet, it is no longer necessary to secure a large space for exhibitions like a record store, so that the distributor can have more songs. In addition, since it is easy for a user to search for a desired music, it is expected that music whose distribution has been reduced after a long time since its release will be used again. However, if there is a charge for the use of music in the same manner as in the conventional music distribution format, there is a concern that only music whose release time is new will be used, and that music whose date has passed since release will not be used.

[0003]

SUMMARY OF THE INVENTION The present invention eliminates the trouble of individually collecting fees for the use of video and music in the distribution of video and music via the Internet, and also provides electronic commerce with security problems. Without losing the interests of video and music producers and distributors. Prevent video and music producers from losing the opportunity to profit from piracy. Further, the present invention aims to increase the amount of distribution even for songs whose distribution has decreased since the release of the music.

[0004]

SUMMARY OF THE INVENTION The present invention relates to the distribution of video and music via the Internet. In order to solve the above-mentioned problems, the video and music are protected from unauthorized reproduction. The video or music will be delivered with an ad at the beginning that includes a way to remove the protection. Then, the distributor takes measures to collect the fee from the advertiser without collecting the fee from the user.

[0005]

According to the present invention, the above means are taken, and in use, a user records video and music with advertisement on a recording medium such as a magnetic disk, a magneto-optical disk, and a semiconductor memory via the Internet. The recorded video and music are played back on the playback device and enjoyed. Since the advertisement is recorded at the head of the video or music, playback is performed from the advertisement.
The playback device temporarily records the flag in the memory when the advertisement ends. This flag is a signal that the ad has been played properly, and if the ad is paused or completely stopped in the middle of the ad, or if the entire ad or part of the ad is fast-forwarded, the flag is not recorded. I do. When the recording of the flag is completed, the reproduction is performed while removing the protection applied to the video and music. The video and music are not normally reproduced unless a dedicated reproduction device is used in order to check whether the advertisement has been reproduced normally or to remove the protection applied to the video or music. Since the user is free to use the music, the number of times that the user uses the music increases as compared with the conventional method that requires a fee. Since there is no charge, songs that have passed since release will be used. Since the distributor collects a fee from a specific advertiser who has contracted according to the actual use of the distribution, it is possible to eliminate the trouble of individually collecting from an unspecified user. The creator of the video or music can receive a usage fee from the distributor according to the actual use of the distribution. In the past, if a copy was made in spite of copy protection to prevent unauthorized copying,
He had unduly lost the opportunity to benefit the creators. But,
According to the present invention, there is no charge for using music,
Advertisers may be more welcome because they can get it directly from the distributor rather than copy it, and even if they do, the advertisement will be copied at the same time and the advertisement will be played at the destination. . Therefore, the advertiser presumes that a copy is made, estimates the approximate number of copies, and pays the advertisement fee to the distributor. By paying the royalties from the distributor to the creator, it is possible to prevent the damage caused by the illegal copying by the conventional method, and protect the profit of the creator of the video and music.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a first embodiment, in which an advertisement is added to the head of music. For example, all bits of the music portion are inverted, and protection is performed so that the music is not normally reproduced as it is. The advertisement includes a method for removing the protection applied to the data and music that causes the playback device to recognize that the advertisement is part of the advertisement. The playback device recognizes the advertisement, checks for pause, complete stop, and fast-forward during playback of the advertisement, and records a flag in memory if the advertisement is played properly. Next, we analyze how to remove music protection. Then, the music is played while removing the protection. Since the music is protected, it cannot be normally reproduced unless the reproducing device has a dedicated reproducing device function. Also, even if a dedicated playback device is used, even if an attempt is made to reproduce only the music portion by separating the music from the advertisement, the reproduction is not properly performed because the protection for preventing unauthorized reproduction has not been removed. The distributor operates based on the advertising revenue from the advertiser, and does not collect from the user. The distributor pays the usage fee to the music producer. FIG. 2 shows a second embodiment. Similar to the music of the first embodiment, an advertisement is attached to a video. Since the cost of producing a video is higher than that of music, it is difficult for one advertiser to bear the cost of distribution, so a plurality of advertisers share the cost. Since video is often played for a longer time than music, advertisements are distributed to various places in the video. As shown in FIG.
Video a, advertisement b, video b, ... advertisement n, video n
・To play a video from the middle, for example,
When playing back the video n, the playback device automatically finds and plays the advertisement n at the beginning. When the reproduction of the advertisement n is completed, a method of removing the protection applied to the video n is analyzed. Thereafter, the video n is reproduced while removing the protection. As in the first embodiment, a video cannot be reproduced unless it is a dedicated reproduction device. Also, even if you use a dedicated playback device,
If the advertisement part is not normally reproduced, the video is not reproduced.

[0007]

According to the present invention, in the distribution of video and music via the Internet, the complexity of individually collecting fees for the use of video and music is eliminated, and electronic commerce with security problems is not performed. It does not detract from the interests of video and music producers. The opportunity to gain the benefit of the creators of video and music by piracy was prevented from being unduly lost. In addition, even for songs whose distribution has decreased since the release of the music, the distribution volume has been increased again.
