On December 1, 2018, "new 4K8K satellite broadcasting" started at last.
In comparison with current digital broadcasting (full high-definition), we can enjoy more high-definition high-resolution Video (super hi-vision) on TV.
Therefore we can appreciate even big-screen TV without coarseness being outstanding in beautiful Video.
Point of 4K TV
The number of the high pixels
As 4K is the number of the 4 times pixels than full high-definition (2K), coarseness is not outstanding in big screen either.
High frame rate
In 4K, Video which is higher than 60 frames is reproduced for one second.
We can enjoy even intense Video of movement more smoothly.
Only as for antenna and the tuner
Should we cope?
Antenna and tuner corresponding to reception of new 4K broadcast are necessary to enjoy new 4K broadcast.
Person whom we already already buy Supported Devices and prepared may come.
Did you buy a new HDMI cable of recorder and tuner which you connected to TV?
In HDMI cable, do you know that there are various standards? Even if HDMI cable varies in standard, shape of connector does not change.
Therefore person who does not buy a new HDMI cable may come even if we buy a new TV and tuner.
High-definition high-resolution new 4K broadcast comes to have a very big data volume to treat.
In HDMI cable which does not support 4K, we cannot fully enjoy precious beautiful Video.
Therefore when connect recorder and tuner to TV, the HDMI cable makes product corresponding to 4K, too; is necessary.
Among HDMI cable, standard supporting 4K is called "Premium HDMI".
Features of Premium HDMI is as follows.
It supports about 800 pixels (resolution: 3840 X 2160) of Video of 4K broadcast. Coarseness is not outstanding in beautiful Video in big screen either.
2 high frame rates
Frame rate is standard to select fluency of Video as. In Video of one second, we express how many frames (still image) you show.
Frame rate of new 4K broadcast 60Hz or more. In other words, more than 60 frames are displayed for one second, and Premium HDMI cable supports this.
3 line speed
Faster telecom speed is sought to become high definition, high frame rate by new 4K broadcast. Premium HDMI supports 18Gbps where 1.8 of standard doubles conventionally.
By new 4K broadcast, we increase the light and shade difference than standard conventionally and can express bright part and partially which gloomy gradation.
Therefore we can see Video with three-dimensional impression in nature near human eyes.
