This study compares Real Time Streaming Protocol (RTSP) and Web Real-Time Communication (WebRTC) for video streaming quality. The developed WebRTC mobile application shows improved performance in reducing stream packet delay compared to popular Android apps.

Area of Science:

  • Computer Science
  • Communication Engineering
  • Software Development

Background:

  • Video streaming is a primary communication method, essential for overcoming distance barriers.
  • Key challenges in video streaming include bandwidth limitations, network congestion, and maintaining quality of service (QoS) and quality of experience (QoE).
  • Real Time Streaming Protocol (RTSP) and Web Real-Time Communication (WebRTC) are prominent protocols in this domain.

Purpose of the Study:

  • To conduct a comparative analysis of RTSP and WebRTC protocols for video streaming.
  • To develop and evaluate novel Android mobile applications implementing RTSP and WebRTC.
  • To assess the impact of connection establishment time and stream reception time on streaming quality.

Main Methods:

  • Development of two new Android mobile applications, one utilizing RTSP and the other WebRTC.
