闭路电视解读5G网络4K视频：更快、清晰_我的网站
一 | "With the support and guidance of our board, we plan to increase our spending from nearly $6 billion per year today to $9 billion per year by 2026. To help make this spending increase possible, I am transferring $20 billion to the foundation’s endowment this month," he said.,Gates added that he plans to give virtually all of his wealth to the his foundation and will move down and eventually off of the list of the world’s richest people.,"I have an obligation to return my resources to society in ways that have the greatest impact for reducing suffering and improving lives. And I hope others in positions of great wealth and privilege will step up in this moment too," he said.,As I look to the future, I plan to give virtually all of my wealth to the foundation. I will move down and eventually off of the list of the world’s richest people.— Bill Gates (@BillGates) July 13, 2022,In May 2021, Bill and Melinda Gates announced their decision to end their marriage. The media reported in April that the two had officially divorced. It has also been reported that Melinda Gates could step down as trustee of the foundation in two years if she is unable to work alongside her former husband.,Bill Gates has a current net worth of $144 billion, according to Bloomberg's Billionaires Index.。1月13日，中央电视台与中国移动、华为共同在广东深圳成功进行5G网络4K电视传输测试。这是我国第一个5G新媒体平台建设后的又一重大突破。那么，用5G网络在线观看4K视频是什么样的体验呢？在这方面，让我们来看看中央电视台新闻的解读。首先，对5G网络的速度进行了研究。
二 | 据央视解读，第五代移动通信技术标准的理论网络速率可达10GB/s（1.25GB/s），是家庭千兆宽带理论峰值速率的10倍（约1GB/s）。
三 | 然而，这个值只是理论峰值，实际使用率也受环境和设备的影响，将远远小于“理论峰值”。据央视数据，目前主流手机wifi连接理论峰值速率为150MB/s，家庭常用100M宽带理论峰值速率为100MB/s，4G网络理论峰值速率为100MB/s（TD-LTE）。也就是说，5G比4G快100倍，除了网络速度的提高，5G网络的延时也会降低，约为1ms，这是保证自动驾驶安全的主要前提条件；5G网络支持每平方公里同时连接上百万台设备，使物联网成为现实。而智能家居则是一个现实；5G网络还支持连接速度高达500km/h的设备，这意味着即使在350km/h的高速铁路上，网络也将被连接起来。你不能被困在这出戏里。为什么5G网络需要在线观看4K视频？为了提高分辨率，视频的总像素也将得到提高。4K视频将是1080p全高清视频总像素的四倍，视频量将更大。据央视数据，4K视频的需求率在40MB/s到60MB/s之间，虽然目前4G网络可以提供100MB/s的峰值速率，但实际使用率在8MB/s到60MB/s之间，不能满足4K视频观看的需求。升级到5G网络，个人最低速率要求提升到100MB/s，即使是最低速率，也能满足4K视频观看。此外，5G网络还可以实现AR增强现实、虚拟现实和未来8K视频在线播放功能。
