电视的标签决定带宽的要求吗?

date:On November 14, 2017 Source:  

   利诺威HDMI光纤种类线材对于现在的电视来说是否也有要求呢,过去标清电视到2K电视的选择还是比较可观的,可是现在的线材高度越来越高,电视的标准也就越高了,不知道何时多处了个4K标签,然而这样的一个标签让电视划分了等级,对于带宽的标准也就多了一个选项,也就只在4K这个词里面,现在就是用标签名来决定4K电视带宽的要求,下面利诺威HDMI光纤结合数字信息知识讲解4K电视标签的带宽选项。

Lenovic HDMI fiber types of wire for the current TV is also required it, in the past SDTV to 2K TV's choice is quite substantial, but now the wire height is higher and higher, the higher the standard TV, Do not know when a 4K tag, however, such a tag for the television division of the level of bandwidth for the standard also had an option, it is only in the word 4K inside, and now is the tag name to decide 4K TV bandwidth requirements, the following LG Roland HDMI fiber digital information combined with knowledge of 4K TV label bandwidth options.

4K技术的发展

   随着视频技术的发展,4k视频在未来几年将逐渐成为主流。如广东省在2017年7月发布《关于开展新数字家庭行动推动4K电视网络应用与产业发展的实施方案》,将力争用3至5年时间建成以4K电视为核心的超高清互动数字家庭网络。

With the development of video technology, 4K video will gradually become the mainstream in the next few years. For example, Guangdong Province announced in July 2017 "Implementation Plan for New Digital Home Operations to Drive 4K TV Network Applications and Industries" and will strive to build a 4K TV-based UHD interactive digital home network in 3-5 years .


   4K可分为三个等级:准4K、基础4K、极致4K。不同等级的4K对画面帧率、抽样比、压缩比、网络传输带宽等都有不同要求,要求越高,体验到的色彩丰富性、画面生动性就越精彩。如极致4K视频需要最高75兆的带宽,而对于家里有多个4K电视的,需要200M甚至500M的带宽,才能满足家庭对4K视频的承载需求。

4K can be divided into three levels: quasi 4K, basic 4K, extreme 4K. Different levels of 4K on the picture frame rate, sampling ratio, compression ratio, network bandwidth, etc. have different requirements, the higher the requirements, experience the richness of color, the more lively screen more exciting. Extreme 4K video requires up to 75 megabytes of bandwidth, while for families with multiple 4K TVs, 200 megabytes or even 500 megabytes of bandwidth are needed to meet the family's need for 4K video.


   那么4K有那几样的标签标准呢?-So what kind of label standard 4K?


   准4k带宽-25~30Mbps- Quasi 4k bandwidth -25 ~ 30Mbps


   基础4K带宽-30~45Mbps-Basic 4K bandwidth -30 ~ 45Mbps


   极致4K带宽-45Mbps~55Mbps-Ultimate 4K bandwidth -45Mbps ~ 55Mbps


   4K视频无疑会对通信网络的带宽和质量提出更高的要求,推动通信产业的发展。一方面,在固定宽带领域,4K视频会推动百兆宽带的普及,对于家里有多个4K电视的,会要求升级到200M甚至500M、千兆。同时为保证视频质量,除了峰值速率,对每用户的保证带宽也提出了更高的要求。这就要求运营商在宽带网络建设时,要用更低的分光比,或者启用下一代PON技术,提供更高的保证带宽。

4K video will undoubtedly put forward higher requirements on the bandwidth and quality of communication networks and promote the development of the communications industry. On the one hand, in the field of fixed broadband, 4K video will promote the popularization of Fast Wireless, and it will require upgrading to 200M or even 500M and Gigabit for home with multiple 4K TVs. At the same time, to ensure the video quality, in addition to the peak rate, guaranteed bandwidth for each user also put forward higher requirements. This requires operators in the construction of broadband networks, to use a lower splitting ratio, or enable next-generation PON technology to provide higher guaranteed bandwidth.
