It also developed various foundational standards for telepresence systems. ITU-T H.323 – the ITU standard for interoperability in audio, video and data transmissions over IP – is the world's most widely used voice over IP (VoIP) communication protocol. SG16 is the origin of a large family of successful videoconferencing systems tailored to several networks: for example, ITU-T H.320 and H.310 for narrow- and broadband ISDN, and H.324 for PSTN and 3rd Generation mobile. Test results demonstrate that VVC provides about a 40% bit rate reduction for 4K/UHD test sequences using objective metrics. H.265/HEVC for equal subjective video quality. VVC is expected to achieve about a 50% bit rate reduction vs. Now the next generation video coding technology called "Versatile Video Coding" (VVC), consented as ITU-T H.266 at SG16 in July 2020. HEVC needs only half the bit rate of H.264 | MPEG-4 AVC, delivering an HD viewing experience while concurrently enabling operators to utilize network capacity more efficiently. H.265 supports more video at higher quality on the available bandwidth. H.264 is the first truly scalable video codec, and continues to deliver excellent quality across the entire bandwidth spectrum – from high-definition television to videoconferencing and 3G mobile multimedia. H.264/AVC and H.265/HEVC remain the most deployed video compression standard worldwide. This collaboration led to two Primetime Emmy award winning Recommendations, the first in 2008 for ITU-T H.264 (or MPEG-4 Part 10 Advanced Video Coding, AVC), and the second in 2017 for High Efficiency Video Coding (HEVC, published as ITU H.265 | ISO/IEC 23008-2). This includes narrowband and wideband speech coders, and work carried out together with ISO/IEC's JPEG and MPEG working groups in image and video compression, including JPEG and JPEG 2000 (ITU-T T.80 and T.800 series) and MPEG-2 Video (ITU-T H.262). In this article we discuss an example use case for a medical application that illustrates the need for the research and development in the iGLANCE framework.SG16 is home to all media coding work in ITU-T and is home to some very well-known standards following a long tradition of work. There are two main application fields within iGLANCE: consumer and medical systems. One of the key components of this system is view interpolation and its related challenges. It consists of free viewpoint video interpolation and coding. We describe the ongoing iGLANCE project and introduce the iGLANCE decoding and rendering system. In this article we discuss an example use case for a medical application that illustrates the need for the research and development in the iGLANCE framework.ĪB - The iGLANCE project aims at researching the methods of receiving and rendering of free-view 3D-TV sequences. N2 - The iGLANCE project aims at researching the methods of receiving and rendering of free-view 3D-TV sequences. T1 - iGlance project: free-viewpoint 3D video
