The electrical-electrical transfer function (EETF), described in International Telecommunications Union—Radiocommunication (ITU-R) BT.2390–7, offers four variations, which allow high luminance imagery to be tone-mapped to a lower luminance in different ways. This is useful when converting high dynamic range (HDR) encoding spaces or rendering HDR content on screens that have limited performance. However, for some input colors, these variations introduce drastic changes in hue, in […]

To include regional contents in a national single-frequency network (SFN), the RAI Radiotelevisione Italiana has studied and tested a system configuration that benefits from the multiple physical layer pipes (PLPs) of Digital Video Broadcasting-Second Generation Terrestrial (DVB-T2) standard in a laboratory. According to the proposed solution, in each region, the national programs are transmitted in one PLP, whereas other k PLPs convey the regional contents of a macroregional SFN, formed by a […]

The shift toward Media-over-IP (MoIP) promises to bring enormous flexibility, on the one hand, but increases the configuration complexity, on the other. Apart from new skill sets, new tools are needed to test, validate, and monitor new devices based on SMPTE ST 2110 and Joint Task Force on Networked Media (JT-NM) TR-1001-1, and ensure interoperability. Moreover, in a large system, there is a significant need for thorough testing that can be repetitive, leading to wastage of precious time. In […]
