Design and implementation of a teleconferencing system using improved HEVC coding

摘要

Teleconferencing has become an indispensable element in any business system, because it offers the opportunity for collaborators to participate in a virtual group while remaining in divergent regions. Teleconferencing also increases productivity, minimizes travel expenses and saves travel time. This paper presents a reliable Teleconference system that utilizes an improved high-efficiency video codec (HEVC) H.265 technology with congestion control. The improvement is based on CU size decision and entropy coding, which provides an adequate approach to enhance the real-time video/IP technology in terms of improved video quality and increased compression ratio compared to the previous codec (H.264) and original HEVC.
