The sports festival is also a festival for broadcasting technology

"NHK Beijing Olympic Site" video distribution page.We distribute live distribution of the Olympics, missed videos, highlight videos, etc.

Ayumi Hirano won a gold medal with a snowboard men's half pipe. It was a great run. However, it seems that there are many people who have missed his brave figure on live TV broadcasts. This is because the run -up run on NHK switched to the sub -channel just before Hirano's run, the third run of Hirano. Digital broadcasting has a multi -channel mechanism, and if sports broadcasting time is extended, it is often the case that a sub -channel broadcast does not respond by changing the normal program formation. This is a mechanism that divides the bandwidth of the radio wave assigned to the broadcast into two and plays another content. The subchannel is one of the main channels, so it's a good idea to press the channel button on the remote control to see it, but it seems that there were a certain number of people who could not do that. Even so, it was the worst timing. Even if I was able to switch to a sub -channel well, the image quality was poor, even though it was a run of a gold medal. It is natural because the number of pixels of the usual broadcast is about one -quarter in terms of resolution. Every time I repeat this experience, I realize that broadcasts using radio waves have a limit. Sports festival that can see the evolution of IT technology. That's why I enjoy this winter with sports broadcasts every day. Worldwide sports competitions are held every two years, alternately for summer tournaments and winter tournaments. Due to the catasis, the summer Tokyo tournament was postponed by one year and held in 2021. I can't help. The tournament is a sports festival and a festival of broadcasting technology, but it is unlikely that you will see the evolution of surprising technologies if the interval is short. Nevertheless, if you look carefully, the shooting method, how to show it, the signage that conveys the progress, and how to convey the aggregation results are steadily improved. And IT is used in various situations. However, the radio waves flying in the sky are the same as 20 years ago. I realize that radio waves are finite resources, and I understand that once I started, I can't change the mechanism, but I'm a little disappointed. The optimal transmission content of radio waves, internet, or content cannot be transmitted without media. In the case of content such as sports broadcasting broadcasts, the transmission route is the media. Whether you use radio waves for the transmission or use a network for content delivery, the user experience differs greatly even if it is the same content. Broadband Internet should be fulfilled, and the evolution of mobile networks will be able to meet the expectations of the general public. However, radio waves are public resources, and broadcasting that uses them is stiff in various laws so that business is not given priority. On the other hand, only one YouTuber carries the camera on its own (although it may only have a smartphone), as well as the appearance, from shooting to editing, configuration, and production alone. It is in the current world that moves the world. Nevertheless, even if a YouTuber wants to cover a global sports tournament, it doesn't come soon. If you can do that, you may be able to do content that you have never seen before. The mechanism that searches for content is still a conventional content that is still in the sea tactic and a rare content made with limited resources. I think it would be nice to be able to enjoy both seamlessly. Therefore, the mechanism of discovery must still evolve. If you can't find it, it's synonymous with the content that doesn't exist. Hirano's gold medal run can always be seen on demand. That was a salvation, but the poor image quality can't be helped. Moreover, it is difficult to find on -demand content, whether you are willing to show it, and what happened.
