Abstract
4K/8K systems are expected to take over HDTV. Commercial 4K broadcasting has started and the 8K
broadcasting is planned for 2018. However, the content is still insufficient. It is a similar situation to that of HDTV in the
1990s’. HDTV content upconverted from analogue TV content was important to supplement the insufficient HDTV content.
The upconverted HDTV content was also important for news coverage because HDTV equipment was heavy and bulky.
Current 4K/8K situation is similar and covering the news with 8K equipment is very difficult because 8K equipment is much
heavier and bulkier than that of HDTV in 1990s’. Currently HDTV content is sufficient and HDTV equipment has matured to
cope with news coverage. Upconverter from HDTV to 8K is a variable candidate to solve the problem. However the
upconversion from the interlaced HDTV to 8K is 32 times enlargement and the upconverted 8K images become very blurry.
The upconverter from HDTV to 8K with super resolution is proposed to fix the blur. In this paper the details are discussed.
