In this technology driven era, effective communication is the backbone for success of any business. In Post- Covid times, effective and engaging digital communications have become integral part of our day to day lives ranging from basic online learning and education delivery to complex remote health care management. This increasing demand has given rise to introduction of many tools to support video conferencing solutions. Many of these tools have limitation that they require dedicated hardware resources and installation of software at client and host end. Increasing use of communication tools inspire us to explore the concept of video conferencing in more depth. The motivation for undertaking this research work is to develop a light-weight chat tool that facilitates peer-peer communication with minimal resources. In simple terms, just a simple web browser at both ends shall be enough to enhance user engagement with customized video calling experiences. Furthermore, many additional attributes like user login authentication, screen recording, screen sharing, text chat, multiuser chat, room management, audio/video controls have been integrated in developed tool. We also performed the performance evaluation of communication quality using various image/video quality measuring metrics like PSNR (Peak signal-to-noise ratio), SSIM (structural similarity index measure) and VMAF (Video Multi-method Assessment Fusion). Our results depict that with the joining of 2
nd and 3rd video stream other than the room creator, the PSNR, SSIM and VMAF values are 28.55, 94.84, 61.24 and 26.24, 93.74, 51.62 respectively. The reduction in PSNR and other video quality metrics is observed due the fact that with addition of each user a noise element is inducted in the communicating system. A holistic performance analysis was also performed using different types of browsers and also varying room-sizes. [ABSTRACT FROM AUTHOR]- Published
