Radio Broadcast Monitoring to Ensure Copyright Ownership

Abstract

In this research, we provide a way to protect copyright ownership of multimedia objects like songs. Protecting ownership is very important when we are working in a corporative environment. If someone tries to misuse others' property it is an illegal action. But capturing theses kind of actions especially on electronic objects are very difficult. There are several ways to share copyright ownership with others. We can purchase others' property and use them under conditions provided by the owner. In this research, we are focusing on protecting ownership of audio songs broadcasted by radio channels. There are so many radio channels in a country, as well as a huge number of songs are broadcasted per day. In order to broadcast particular song in a radio channel, they should purchase the right to do so. In order to make sure that this process is functioning correctly, we have to monitor radio channel and extract the broadcasted songs. Currently, this is happened manually. Manual process is no longer able to continue because the number of songs is increasing day by day. We provide an automated solution for this real-world problem. There are so many researches on this area done by various researches. They used different approaches to achieve the final goal. Most of them have used content base audio identification base approaches. In this context, an unknown audio file is identified by analysing the content of it. But, it is very hard to find researches that use this concept to monitor radio channel since there are additional complexities when we come to monitor radio channel. In this research, we extend the content-based audio identification approach to monitor radio channel automatically. First, we perform a pre-process on raw audio objects that broadcasted by a radio channel. After extracting interest areas, we generate set of hash values. Then, we perform powerful approximate matching against pre-stored hashes. Ultimately, we provide a detailed report which contains all the information of broadcasted audio songs.

Protecting Copyright Ownership via Identification of Remastered Music in Radio Broadcasts

“…In general, the current automatic monitoring systems designed to identify remastered music in radio streams exhibit limited effectiveness when radio stations modify the signals in either the time or frequency domain. The approach proposed by Senevirathna et al [5] assessed their model through various scenarios, including mixing non-song elements (such as commercials and dialogues) and introducing non-song elements in the middle of song broadcasts, as well as adding noise to the song broadcasts. However, this method did not evaluate their model's performance against alterations in the time and frequency domains.…”

“…Some approaches have been specifically developed to ad-dress copyright ownership protection in the context of monitoring radio broadcasts. In 2018, Senevirathna et al introduced a music identification algorithm focused on identifying Sinhala songs in radio broadcasts [5]. The algorithm utilised STFT representations and extracted local spectral peak values from five frequency bins selected in the mid-range of the frequency axis.…”

“…To address this, a certain degree of overlap is introduced in the series of windows used to generate the STFT of the audio segment, aiming to minimize information loss [22]. This study utilizes a 2048-bitlong window with 50% overlapping, a common overlapping proportion in the audio domain [5]. Figure 2 illustrates this.…”

“…In 2018, Senevirathna and Jayaratne [5] introduced a technique for identifying content in radio broadcasts. This method involves parallel monitoring of the radio stream and generating fingerprints through the hashing of spectral peaks in Short Time Fourier Transform (STFT) spectrograms.…”

Classification of Voice Content in the Context of Public Radio Broadcasting

“…Hence, for the purpose of measuring the performance of a broadcast program, radio stations need to monitor the broadcasting content regularly. Broadcast content monitoring helps to verify when and where the broadcast content placed, protect copyrights by knowing precisely how the content is being used, and measure performance across other broadcast channels [2,3,4,5,6]. Therefore, broadcast content monitoring is a necessary thing for radio stations.…”
