Ultra-High-Definition Television and Its Optical Transmission

Abstract

SUMMARY'Super Hi-Vision' (SHV) is promising as a future form of television. It is an ultra-high definition TV system that has 16 times the number of pixels of HDTV and employs a 22.2 multichannel sound system. It offers superior presence and gives the impression of reality. The information bitrates of the current prototypes range from 24 to 72 Gbit/s, and a fiber optic transmission system is needed to transfer even just one channel. This paper describes the optical transmission technologies that have been developed for SHV inter-equipment connects and links between outdoor sites and broadcasting stations.

Field transmission of an uncompressed 8K ultra-high definition television optical signal with forward error correction codes

“…The number of links depends on the frame rates (24 to 120 Hz) and on the sampling structures of the 8K image. Figure 1(a) shows an overview of the interface mapping of a 72 Gb/s 8K image with a 60-Hz frame rate [6] into twelve 10G links. The three color components (red, green and blue) that constitute the 8K image are respectively divided into four to produce twelve 4K sub-images.…”

[Survey paper] A Review of Broadcasting Technology

“…Current digital cables predominantly utilize 64QAM, but 4096QAM has been standardized in DVB-C2 40) . It is now possible to transmit uncompressed Super Hi-Vision over optic fiber 41) . Moreover, Super Hi-Vision has been transmitted over long distances on a global IP network 42) .…”

Service-Oriented Control Framework for Next Generation Media Applications Over Future Networks

“…The data intensiveness of these formats precludes the use of traditional IP networks [5]. The distribution of uncompressed data streams for film postproduction or critical scientific and medical applications requires up to 8 Gb∕s and 72 Gb∕s for 4K and UHD, respectively, [5,6]. For live video and video-on-demand (VoD) streaming applications, advanced compression technologies based on JPEG2000, H.264, and the more recent H.265 standard, can reduce these requirements to about 250 Mb∕s and 300-500 Mb∕s for 4K and UHD, respectively, [7][8][9].…”

“…A number of works have proposed optical transmission systems for DC and UHD television broadcasting applications [6,9]. However, these works have focused on the implementation and trial of novel encoder/decoder (codec) and streaming systems, and not on the design of architectures for end-to-end delivery of networked media services using 4K and UHD.…”
