Super Hi-Vision multi-channel satellite transmission experiment with too much super-high speed internet satellite "KIZUNA" in STRIKE OPEN 2009

With regard to the "Super Hi-Vision" that exceeds the current HDTV, various technologies have steadily advanced steadily, and this timeSTRL Open 2009, There is prepared a Super Hi-Vision Theater which can experience 22.2 multi-channel sound which surpasses 33 million pixels, which is 16 times the Hi-Vision currently being broadcast, surround 5.1 ch. Besides that, the Wideband Super Hi-Vision transmission experiment with this WINDS satellite is wonderful. If you've actually done movie editing and have encoded and decoded it, it is a content that makes it even more appreciated.

As a content, live broadcasting from Sapporo by Super Hi-Vision (video bit rate is really 24 Gbps, audio only 27.6 Mbps) is transmitted in real time from H in antenna in the vicinity of the entrance of the Broadcasting Technology Laboratory It is encoded with .264 etc. and received within 100 Mbps and received via the ultra high speed Internet satellite "KIZUNA" (speed is 370 Mbps to 500 Mbps), and at the same time also from Kashima Space Technical Center, another Super Hi - Vision image (encoded With a bit rate of 100 Mbps).

A report that can catch a glimpse of the aggressive technical power of NHK is as follows.

On the whole it looks like this


Outline of super Hi-vision satellite transmission experiment


Explanation of the way of how to reach Sapporo in Hokkaido to Setagaya ku, Tokyo


Specifically, it is like this


A big deal


The tip of the antenna


Hitting and changing, this time to the indoor exhibition. This is a channel changer.


Encoding is done by this procedure. Uncompressed Super Hi-Vision video is a tremendous bit rate of 24 Gbps. Even sound alone requires 27.6 Mbps. We encode this in MPEG-4 AVC / H.264 format and audio in MPEG-2 AAC format. As a result, the encoded Super Hi-Vision video / audio stream is within 100 Mbps and is decoded in real time via satellite. Simply put, it's just a combination of movie encoding and decoding, but it's bigger and it's not that the amount of data, speed and real-time nature are not half full. If you are a person who has done movie editing, I think that you can really feel how amazing this is.


The satellite transmission parameter is like this, the transmission bit rate is dependent on the method, but it is 370 Mbps to 500 Mbps. It is certainly not ashamed of the name of the ultra-high speed internet satellite.


Looking at it again, NHK is a figure that seems to ask about 1 million times about what to do live broadcasting from where. Perhaps it is possible to realize a sense of reality at an unprecedented level, but if you can not catch up with any commercial other than NHK ... ....


This is a device to decode super Hi - Vision sent from the satellite. Or it seems to be only a server rack.


Received signals from ultra-high speed internet satellite "KIZUNA" are also monitored in real time. I feel radio waves through space.


It makes me feel like I'd like to paste it because I can make a label such as "satellite" at once


And this is the Super Hi - Vision image that is actually being sent live from Sapporo.


It will do a demo with such feeling. Rather than saying that I am watching the monitor, I feel that I am looking out from the "window".


A state of live broadcast from Sapporo. The sound is difficult to understand in the movie, but it really makes me feel like I am looking outside from this position in Sapporo.


Super Hi - Vision video being sent at the same time. It is 96 Mbps for video alone and 2 Mbps for audio.


It is like this. I do not know what is different from what is in front of my eyes.


Perhaps the day will come when Internet streaming will be possible at this level, but I am astonished at the fact that the technology that can realize the presence here far in remote areas has reached here . Another thing that makes me sad more is that this greatness will not be totally transmitted by hand-held cameras and the like. As we are doing this Sunday, 24th, we recommend going to see and experiencing once. I thought, "I do not see any TV anymore", but I changed my mind and changed my mind and became a feeling that "Nobody seems to see anything other than NHK in the future".
