This paper provides a comprehensive analysis of the implications of the metaverse on the music industry, focusing on copyright issues and potential solutions. It delves into the concept and characteristics of metaverse platforms, describing them as environments that immerse users in a variety of virtual experiences. A significant portion of the paper is dedicated to exploring music use and copyright infringement in the metaverse. It examines how users incorporate existing music into their content, often leading to legal challenges due to copyright infringement. The paper discusses the role of online service providers (OSPs) in this context and the legal implications of their actions. The paper also addresses the 'safe harbor' provisions for OSPs and examines the balance between protecting rights holders and limiting OSP liability. It highlights the challenges and limitations of copyright enforcement in the metaverse, especially given the unique nature of content on platforms such as Roblox. Finally, the article proposes solutions to simplify music licensing in the metaverse, suggesting a shift from property rules to liability rules and the establishment of Collective Management Organizations (CMOs) to streamline the licensing process and better protect copyright holders' interests.

Due to social distancing caused by COVID 19, music concerts have not been allowed at home and abroad, and it is not known when overseas concerts will be able to resume unless the pandemics calm down, even if they are available. Meanwhile, people consume much more content through online services such as Netflix and YouTube than before. Under these circumstances, the music industry expects the virtual livestreamed performance to restore sluggish live performances again and bring about a digital renaissance. It also leads to the issue of reestablishing a copyright system regarding a livestreamed performance and of preparing a new rate of royalty standards for the use of works in OTT. In addition, a multi-territorial licensing of r ights in musical works is necessary to resolve copyright issues efficiently by applying the same term s to all countries from where the audience comes. In this paper, I examine the legal nature and the decision of copyright fees of performances as an integral part of the music industry.

Many young people, who are most affected by TV audition programs and the K-pop craze, have begun to choose careers in music. They attended music classes through academies or took private lessons, and then went on to a college's practical-music department. As the number of applicants increased, competition for university practical-music programs increased abnormally. As a result, many students then started learning music at an early age through private educational institutions and academies. Afterwards, as high schools related to practical music began to appear, the number of students entering practical-music high school and technical schools increased. However, a big problem in practical-music high schools was difficulty in finding professional teachers who majored in music. This arose because it was difficult for someone with a practical-music major to acquire a full-time teaching certificate. There are many ways to obtain a teacher's license, but the only option for practical-music majors is to graduate from the Graduate School of Education. However, since the Graduate School of Education is limited to classical and traditional music, admission itself is difficult. Even if someone is accepted by the school, most of the courses consist of classical music and traditional music education, which is very difficult for someone who majored in practical music. Therefore, in this thesis, we study the current situation in practical-music high schools, looking at why a regular Level 2 teaching certificate is needed and how to obtain one.

Internet purchase is increasing according to the activation of Electronic Commerce. Currently, the hardware is main purchase items in the Electronic Commerce. The on-line purchase of digital product, that is electronic file type of product, has many merits such as, does not cost in logistics, is ease of searching the product, and is possible of 'Try and Buy' system. But, actually digital products have not been major product and Cause of its piracy problem. Therefore, the tchnology of digital rights management is focused within EC. The piracy problem of digital products comes from the lack of safety in DP license control technology. Current EC has no method to identify the object that has the right to use the digital product. The protecting of object change is impossible and the protection of hacking is not enough and EC has many problems in efficient license control because of the incompletion of EC structure. In this paper, we propose the design and implementation of on-line circulation system, which can activate on-line circulation of MP3 digital data product in EC, by using the new license control technology, that is Dynamic License Control technology.

The patent right is that creators are received the right of monopoly for supporting their creation work perseveringly but sometimes it causes infringement of freedom of creation. In this study, we examine the patent of music game in arcade game field and also examine Konami's, which is a main producer in this field, institutes many lawsuits repeatedly. It brought on diversion of rivals and depression of game market. We examine the abuse of music game patent through the case of Konami. We examine the negative influence through all music game market that creativity blocked by repetitive patent lawsuit institutes from little change of operation device and music game hardware even though it is reasonable for guarantee of new technology patent in game field which is a idea industry. We examine the lawsuit cases of abuse of music game patent in Korea, China and Japan and we analyze market change through the cases. We recommend policy for this industry development.

The purpose of this study was to investigate music therapists' awareness of the music therapy national certification (MTNC). Online questionnaires were distributed to music therapists who voluntarily agreed to participate in this research and 143 completed surveys were collected for analysis. The questionnaire consisted of 37 questions (background information, awareness of the necessity for MTNC, expected effects of national certification, and qualification management). According to the collected data, music therapists reported that they were highly aware of the necessity for MTNC. The participants believed that excessive issueing of private licenses might deteriorate the quality of music therapy services and job opportunities. As alternatives to address private license-related issues, participants agreed with the establishment of national certification system. Given that participants did not have enough knowledge of MTNC and the MTNC may have both pros and cons, the results should be generalized with caution. Still, this study could provide basic information for further discussion on the establishment of MTNC.

Since the introduction of MP3 players, CD recordings have gradually been vanishing, and the music consuming environment of music users is shifting to mobile devices. The introduction of smart devices has increased the utilization of music through music playback, mass storage, and search functions that are integrated into smartphones and tablets. At the time of initial MP3 player supply, the bitrate of the compressed music contents generally was 128 Kbps. However, as increasing of the demand for high quality music, sound quality of 384 Kbps appeared. Recently, music content of FLAC (Free License Audio Codec) format using lossless compression method is becoming popular. The download service of many music sites in Korea has classified by unlimited download with technical protection and limited download without technical protection. Digital Rights Management (DRM) technology is used as a technical protection measure for unlimited download, but it can only be used with authenticated devices that have DRM installed. Even if music purchased by the user, it cannot be used by other devices. On the contrary, in the case of music that is limited in quantity but not technically protected, there is no way to enforce anyone who distributes it, and in the case of high quality music such as FLAC, the loss is greater. In this paper, the author proposes an audio watermarking technology for copyright protection of high quality stereo music. Two kinds of information, "Copyright" and "Copy_free", are generated by using the turbo code. The two watermarks are composed of 9 bytes (72 bits). If turbo code is applied for error correction, the amount of information to be inserted as 222 bits increases. The 222-bit watermark was expanded to 1024 bits to be robust against additional errors and finally used as a watermark to insert into stereo music. Turbo code is a way to recover raw data if the damaged amount is less than 15% even if part of the code is damaged due to attack of watermarked content. It can be extended to 1024 bits or it can find 222 bits from some damaged contents by increasing the probability, the watermark itself has made it more resistant to attack. The proposed algorithm uses quantization in DCT so that watermark can be detected efficiently and SNR can be improved when stereo music is converted into mono. As a result, on average SNR exceeded 40dB, resulting in sound quality improvements of over 10dB over traditional quantization methods. This is a very significant result because it means relatively 10 times improvement in sound quality. In addition, the sample length required for extracting the watermark can be extracted sufficiently if the length is shorter than 1 second, and the watermark can be completely extracted from music samples of less than one second in all of the MP3 compression having a bit rate of 128 Kbps. The conventional quantization method can extract the watermark with a length of only 1/10 compared to the case where the sampling of the 10-second length largely fails to extract the watermark. In this study, since the length of the watermark embedded into music is 72 bits, it provides sufficient capacity to embed necessary information for music. It is enough bits to identify the music distributed all over the world. 272 can identify $4*10^{21}$, so it can be used as an identifier and it can be used for copyright protection of high quality music service. The proposed algorithm can be used not only for high quality audio but also for development of watermarking algorithm in multimedia such as UHD (Ultra High Definition) TV and high-resolution image. In addition, with the development of digital devices, users are demanding high quality music in the music industry, and artificial intelligence assistant is coming along with high quality music and streaming service. The results of this study can be used to protect the rights of copyright holders in these industries.

The National Conference of Commissioners on Uniform State Laws promulgated the Uniform Computer Information Transactions Act (UCITA) in 1999. In 2000 and 2002, this Act was also Amended. UCITA provides a comprehensive set of rules for licensing computer information, whether computer software or other clearly identified forms of computer information. Computerized databases and computerized music are other examples of computer information that would be subject to UCITA. It would also govern access contracts to sites containing computer information, whether on or off the Internet. UCITA would not govern contracts, even though they may be licensing contracts, for the traditional distribution of movies, books, periodicals, newspapers, or the like. Part 8 of UCITA provides a remedy structure somewhat modeled on that of Article 2 but adapted in significant respects to the different context of a computer information transaction. For example, 808 of UCITA recognizes the focus in a license context for a licensor's remedy should properly be on recovery for benefit conferred or for lost profit, rather than on damage measurement by a substitute transaction, where the license is non-exclusive so additional transactions are permitted and there is very little cost in reproduction of the information and its redistribution. Section 816 of UCITA also contains very important limitations on the generally recognized common law right of self-help as applicable in the electronic context.

There are lots of limits on preventing illegal transaction of digital contents by existing DRM(Digital Right Management) methods because of illegal download and share of contents, which is resulted from advanced information technologies, development of cloud services, and smart instruments. In the other hand, the number of creators based on one person, in the area of music, webtoon, digital magazine and video, is increasing. As a result, it is needed that the necessities of digital contents transaction under the condition of convenience and efficiency through licence and management of contents to protect copyright of contents and to increase the transaction of digital contents. Therefore how to promote the transaction of digital contents should be studied by way of research analysis of contents market through interviewing experts in business.

P2P(Peer To Peer) system, a most attractive file sharing system, is the largest channel of contents distribution and it takes 50% of network traffic. But P2P systems are infamous for used to illegal contents distribution channel not only in music industry, but also in movie industry. But, DRM(Digital Right Management) enabled P2P models are not suggested until now that interrupting illegal contents distribution and keeping advantage of P2P. So in this paper, we suggest a DRM enabled P2P model that can support distributed processing ability and high scalability with no modification in exist P2P model or architecture.
