This paper introduces the world’s first video and audio codec system that complies with 8K broadcasting standards and describes transmission experiments via a broadcasting satellite using this system. 8K Super Hi-Vision (8K) is a broadcasting system capable of highly realistic 8K Ultra High Definition Television (UHDTV) video and 22.2 multichannel audio. In Japan, domestic standards for 8K broa...
An efficient resource allocation is important to guarantee the best performance with a fair distribution of multi-beam satellite capacity to provide satellite multimedia and broadcasting services. In this way, available bandwidth and capacity problems in new satellite system likes Multi-Input-Multi-Output (MIMO), exploring new techniques for enhancing spectral efficiency in satellite communicat...
The migration from analog to digital of the broadcasting technologies, already well consolidated for satellite systems, is becoming a reality also for terrestrial transmission. Digital Terrestrial Television (DTT) is also evolving to offer interactive services and a degree of flexibility which can be exploited to offer tailored applications to users which include, for instance interactivity, di...
Due to its high-performance broadcast capability, -ary phase-shift-keying (MPSK) direct sequence code division multiple access (DS/CDMA) technique is widely used in terrestrial and satellite communications to provide wired/wireless services such as audio broadcasting, video broadcasting and high-speed data transmission. However, both coherent and noncoherent MPSK modulation schemes are sensitiv...
