Codecs de vídeo para transmissão em tempo real: descrição e comparação dos padrões atuais com os novos

Abstract

Deals with the codecs for real-time video transmission. In the course of it, will be set out and explained the main difficulties in the computer network for the transmission of these videos. The main developments and descriptions of coding and compression standards such as, for example, known also as HEVC standard H.265 codec. A description of the new standard HEVC (H.265) containing the improvements presented in this new standard was made. There will be a comparison of the new standard H.265, which obtained a reduction of bandwidth utilization in the transmission and reception of video approximately 40% compared to its predecessor, the H.264 codec, and will also be addressed developments H. 265 codec, which has evolved for the development of codecs for transmission of 3D video and the possibility of increased quality and a greater sense of reality in the transmission and reception of video in real time.
