The development of digital technology and the Internet has brought about a great change in the content industry. In order to keep pace with these changes, the copyright law has undergone several revisions, and the concept of "digital sound transmission" was introduced in the 2006 revision. However, in the current law, digital audio transmission is problematic in that the criteria for distinguishing between broadcasting and transmission is abstract and unclear. This ambiguity makes it difficult to judge the legal status of new music webcasting service such as "Free Litsen". Although these services are positioned as digital audion transmission, they have created a new concept of pseudo transmission because of its similarity to the audio transmission in its convenience and utility. These problems stem from the imbalance of between the development of technology and the legal system, so the change of the legal system is inevitable. Thus, this study discusses US copyright law and related cases, and then suggests solutions for pseudo transmission problems. This study suggests legislative criteria for pseudo transmission problems and legislative measures that can reduce the actual damage to the music market.

In this paper, we propose a resolution enhancement method for estimating direction-of-arrival(DOA) of narrowband incoherent signals incident on a general array. The resolution of DOA algorithm is dependent on the aperture size of antenna array. But it is very impractical to increase the physical size of antenna array in real environment. We propose the method that improves resolution performance by virtually expanding the sensor spacing of original antenna array and then averaging the spatial spectrum of each virtual array which has a different aperture size. Superior resolution capabilities achieved with this method are shown by simulation results in comparison with the standard MUSIC for incoherent signals incident on a uniform circular array.

The phenomenon of vocal vibrato may be regarded as an acoustic representation of one of the most rapid and continuous changes in pitch and intensity that the human vocal mechanism is capable of producing. Singers are likely to use vibrato effectively to enrich their voice. The purpose of this study was to obtain acoustic measurements (vF0 and vAm) of 45 subjects (15 trot and 15 ballad singers and 15 non-singers) and to compare acoustic measurements of the vowel /a/ produced by 3 groups on 2 voice sampling conditions (prolongation and singing of /a/). Thirty singers of trot and ballad were selected by a producer and a concert director working for the KBS (Korean Broadcasting System). The MDVP was used to measure the acoustic parameters. A two-way MANOVA was used for statistical analyses. The results were as follows; Firstly, there was no significant difference among the 3 groups in vF0 and vAm in prolongation of /a/, but in singing voice, there was a significant difference among 3 groups in vF0 and vAm. Secondly, there was an interaction between music genre and voice sampling condition in vF0, and vAm. Finally, trot singers sing with more vibrato than ballad singers. It was concluded that it is very important to analyze singers' voice including various voice conditions (prolongation, reading, conversation, and singing) and to identify differences of singing voice characteristics among music genre.

With the recent increase in YouTube content, many YouTubers are shooting with a handheld camera. Audiences are increasingly accustomed to the movement of handheld cameras. As the camera moves faster than the camera movement of the old movies, and the camera moves splendidly to the music of the music video, the camera movement in CG animation is also needed to change. The handheld Steadicam creates a natural camera movement by compensating so that the screen does not vibrate significantly even when the vibration is large and by minimizing rotation. In order to implement such camera movement, we tried to make a handheld Steadicam using nParticle simulation of Maya software and apply it to the scene to verify whether it is possible to implement the necessary natural and various movement.

In this paper, a new wireless internet service for TV is proposed using the detection of a mobile agent of each mobile company Especially. new broadcasting programs like as music charts. quiz games can be serried by a mobile internet phone. In this proposed system, all mobile protocols( WAP, ME. W3C) are supported by one server based on the mobile agent detection of URL over the existed wire and wireless internees.

Blues음악은 가장 오랜 세월 동안 가장 많은 장소에서 연주되는 음악장르로서 Jazz를 포함한 소위 실용음악분야 전반에 걸쳐 지대한 영향을 끼쳤다. 이토록 강력한 Blues음악의 생명력은 Bluenote에 기인한다 할 수 있으며 이러한 Bluenote와 Jazz음악의 상징이라 할 수 있는 Altered 스케일간의 연관성을 제시 함 으로서 Blues음악의 중요성을 재조명 하고자 한다.

초창기 Blues음악에서의 Bluenote는 단지 b3rd와 b7th음만을 상징하는 국한된 의미로서 사용되어졌다. 하지만 이후 Jazz Blues라는 장르를 통해 복잡한 구조의 화성진행과 더불어 다양한 코드스케일들이 사용되면서 Bluenote에 대한 새로운 개념정리의 필요성이 요구되기 시작했다. 따라서 본 논문은 Bluenote의 본질과 변천과정에 대한 재조명과 함께 Bluenote의 Modern Concept을 중심으로 연구되어 질 것이다.

다양한 홀에서 물리적으로 운동하는 사운드를 미리 예측한다는 것은 매우 어려운 일이다. 자유롭게 운동하는 사운드를 예측/분석할 수 있는 과학적인 소프트웨어는 사운드 엔지니어에게 많은 도움을 준다. 소리의 물리적 운동 방향(Sound Directivity), 거리에 따른 타임 딜레이(Time Delay), 스피커의 각도와 적정한 SPL(Sound Pressure Level)을 과학적인 근거에 의해서 정확한 값을 산출하여 음향 장비 설치이전에 미리 예측하여 음향 디자인을 완성한다면 시간과 비용을 획기적으로 줄일 수 있다. 본 연구은 현재 개발 과정에 있거나 혹은 사용되어지고 있는 소리 예측 프로그램을 분석하여 보다 진보된 소리예측 프로그램을 개발하고자 함이다.
