With the growing data consumption of emerging video applications and users’ requirement for higher resolutions, up to 8K, a huge effort has been made in compression technologies. Recently, versatile coding (VVC) standardized by moving picture expert group (MPEG), providing significant improvement performance over its predecessor high efficiency (HEVC). In this paper, we provide comparative subjective quality evaluation between VVC HEVC standards 8K resolution videos. addition,...
In this paper, we propose, through an objective study, to compare and evaluate the performance of different coding approaches allowing delivery 8K video signal with 4K backward-compatibility on broadcast networks. Presented include simulcast single-layer signals encoded using High-Efficiency Video Coding (HEVC) Versatile (VVC) standards, spatial scalability SHVC base layer (BL) enhancement-layer (EL), super-resolution applied VVC after decoding reach resolution. For up-scaling, selected...
The latest video coding standard, called versatile (VVC), includes several novel and refined tools at different levels of the chain. These bring significant gains with respect to previous high efficiency (HEVC). However, encoder may still introduce visible artifacts, mainly caused by decisions applied adjust bitrate available bandwidth. Hence, pre post-processing techniques are generally added pipeline improve quality decoded video. methods have recently shown outstanding results compared...
The Digital Video Broadcasting (DVB) has proposed to introduce the Ultra-High Definition services in three phases: UHD-1 phase 1, 2 and UHD-2. specification includes several new features such as High Dynamic Range (HDR) Frame-Rate (HFR). It been shown studies that HFR (+100 fps) enhances perceptual quality this enhancement is content-dependent. On other hand, brings challenges transmission chain including codec complexity increase bit-rate overhead, which may delay or even prevent its...
