4.2 Expectation for New Video Coding Technology
In order to utilize the UHD video with 4K and 8K resolutions, it is insufficient to
use the present standard (AVC/H.264) which was standardized for the purpose of
the coding video with the resolution up to HD. New video coding technology will
be required, which compresses video greater while maintaining the high quality of
an original video as much as possible. New video coding technology has a possi-
bility to change SD/HD video compressed by MPEG-2 or AVC/H.264 into
HD/UHD video and to exchange the television broadcasting which is the most fa-
miliar video media to the next generation TV.
5 Progress of Device Technologies Supporting UHD Video
There are several base technologies such as camera, display, storage, transmission
system and video coding, which can realize next generation UHD video technol-
ogy. There have been remarkable achievements in these areas until now. There-
fore, we will soon be able to realize UHD video. In the following, the present
status of camera, display, storage and digital network, is surveyed.

Device technologies for realizing UHD video
5.1 Video Capture Device
Pixel size reduction of the image sensors for digital video cameras, in which high
speed pick-up is possible, has progressed and the realization of high resolution cam-
eras is ready.
With regards to consumer cameras, small camcorders that fit in the hand also
support HDTV resolution with remarkably low price. Moreover, in professional
use, several cameras with support of 4K resolution have already been announced
