# Analysis of Video Transmission Capabilities in a Simulated OFDM-Based Supplementary BPL-PLC System
## 5 Conclusions  
As shown, in case of our custom-designed OFDM-based transmission system, BPL-PLC technology has shown the potential for becoming a reliable supplementary video

communication system. According to the quality analysis, a noticeable difference was only observed from a particular breakpoint in case of SNR: in this case, higher than 28 dB, where the level of noise, color distortions, etc., was acceptable and enabled to determine characteristic elements in the video sequence.  
It should be pointed out that a similar solution has not yet been described in available literature so far. Such activities require a wide range of interdisciplinary skills from many fields of science and technology, with particular emphasis on computer science, telecommunications, coding and transmission techniques, as well as processing and analysis of multimedia content. For this reason, in the near future, we would like to focus on the practical and final implementation of our solution in the form of physical devices and proprietary software. Similar research, carried out by other authors and research centers from around the world, would certainly contribute to accelerating this process and the exchange of information.  
Undeniably, it would be interesting to examine a broader range of video content, including different resolutions as well as file formats. Such an investigation, including, i.e., various technical and subjective quality aspects, would be particularly interesting for a broad group of scientists. Professionals from the oil and mining industry would surely welcome any novel reliable and dependable services [46]. Furthermore, it would be stimulating to broaden the range of research scenarios and interested third parties involved in similar studies. Due to the current situation, and with the aid of modern ICT solutions, it would be fascinating to carry out new studies utilizing, i.e., crowdsourcing methods [47; 48; 49; 50]. A source of inspiration for further studies, including content storing and processing mechanisms, wired and wireless communication media and standards, etc., may be found in [51; 52; 53; 54; 55; 56; 57].
