Application of a reliable audio-video communication system, brings many advantages. With the spoken word we can exchange ideas, provide descriptive information, as well as aid to another person. With the availability of visual information one can monitor the surrounding, working environment, etc. As the amount of available bandwidth continues to shrink, researchers focus on novel types of transmission. Currently, orthogonal frequency division multiplexing (OFDM) is widely utilized both in wired and wireless transmission. In this paper we investigate the quality of service (QoS) parameters of a simulated data transmission system, dedicated particularly to audio and video content distribution with orthogonal frequency division multiplexing. The audio research part involves a group of four language sets, namely: American English, British English, German, and Polish, processed using the Ogg Vorbis format. Whereas, in the video part we investigate a set of MPEG-4 video sequences coded at standard resolution of 480 × 270 pixels. Tests were performed under varying network and bandwidth conditions, including signal-to-noise ratio (SNR) and bit error rate (BER). Results of this study may aid parties interested in designing additional backup or supplementary services for portable devices and user terminals, including reliable means of contact, surveillance and monitoring for the Industry 4.0 and Internet of things (IoT) concept.
