摘要

本文的目的是研究使用压缩技术(H.264和H.265)和分辨率(4K, 2K，全高清和标清)的连续B帧在电视系统中改变其质量时的影响。分析了一组图像(GOP)中连续B帧数为B = 0和B = 4的情况。对压缩比、峰值信噪比(PSNR)、比特率、P帧和B帧等参数的分析结果以表格和图形的形式给出，并据此得出结论。

The impact of successive B frames on TV signal using different compression techniques and video resolution

The aim of this paper is to examine the impact of successive B frames using compression techniques (H.264 and H.265) and resolution (4K, 2K, Full HD and SD) when changing their quality in a television system. The analysis was done for a case when the number of successive B frames in the Group of Pictures (GOP) was B = 0 and B = 4. The results obtained for analysis parameters: compression ratio, Peak Signal Noise Ratio (PSNR), bitrate, P frames and B frames are presented by tables and graphics, based on which conclusions were made.

期刊介绍： The TELFOR Journal is an open access international scientific journal publishing improved and extended versions of the selected best papers initially reported at the annual TELFOR Conference (www.telfor.rs), papers invited by the Editorial Board, and papers submitted by authors themselves for publishing. All papers are subject to reviewing. The TELFOR Journal is published in the English language, with both electronic and printed versions. Being an IEEE co-supported publication, it will follow all the IEEE rules and procedures. The TELFOR Journal covers all the essential branches of modern telecommunications and information technology: Telecommunications Policy and Services, Telecommunications Networks, Radio Communications, Communications Systems, Signal Processing, Optical Communications, Applied Electromagnetics, Applied Electronics, Multimedia, Software Tools and Applications, as well as other fields related to ICT. This large spectrum of topics accounts for the rapid convergence through telecommunications of the underlying technologies towards the information and knowledge society. The Journal provides a medium for exchanging research results and technological achievements accomplished by the scientific community from academia and industry.
