Design And Simulation Of Audio Over Ip (AoIP) Frequency Modulated (FM) Broadcast Studio System (88-108mhz)

ABSTRACT

Communication Protocols are the key tools for data transmission; most of them were defined for asynchronous data transport. Underpinning the Internet is the Internet Protocol (IP), which, has offered an ideal pathway for general Information Technology convergence with its capability of carrying large variety of signals (audio, control, voice, video, data, etc.). This thesis is on “the Design and Simulation of Audio Over IP (AoIP) frequency modulated broadcast studio system”. Using a digital microphone, radio signal is introduced into the system, the introduced signal transported within an IP based Local Area Network is mixed with a combination of digitally networked console/mixer, CD/Tape recorder and computer system to produce an output signal routed across the network and modified/edited to produce radio programs, jingles, commercials, intro, call sign etc. A dedicated server within the network is used to store these programs from where the programs are cued for airing. The studio output signal is excited and amplified severally with a transmitter to produce radio frequency signal within the FM frequency range. This can be received by multiple listeners within the given range. With the aid of a Studio Transmitter Link (STL) and a Satellite link the studio output signal is sent to other network stations. This research work is a new studio automation technology for audio signal transmission in radio stations within FM range (88-108MHz). The work proves a perfect replacement for traditional form of audio signal transport. Educational Studios, Radio Broadcast Studios, Music Studios would find this very resourceful.
