热炒的8K时代,板上钉钉却也任重道远

2017-08-28 09:15:51   中国经济网

根据计算机电脑杂志日期的一则报道,8K技术位列外媒评选出11大过度热炒的技术之一。而当前,在彩电业市场进入寒冬期后,以技术为核心驱动的高阶竞争时代里,8K技术又成为家电企业纷纷追逐的对象,众多家电企业开始涉足8K技术,就连知名家电品牌夏普也不例外,最近放出消息称,本月底夏普将发布首款消费级8K电视新品。

8K曾经离我们非常遥远的名字,一下子变得热络起来,甚至在整体家电行业中出现了8K时代到来的呼声。按照相关专家的解释,8K顾名思义,其拥有的7680x4320的分辨率差不多是4K的四倍,1080P的16倍。横向7680个有效像素点,纵向4320个有效像素点,能够带来极致的画质体验,画面细腻程度的确是无可比拟的。

从目前家电企业所释放的消息,8K技术似乎已经被掌握,但问题恰恰在于技术领先不一定代表消费领先,技术的单点突破,不代表行业的整体提升。在4K尚未得到广泛普及应用的当下,8K要想实现弯道超车,开启一个全新的影像数据价值时代,尽管技术层面已经板上钉钉,但改写行业格局依然是任重道远。

首先,在如今这样一个互联时代,电视已经不再是过去的电视,抛开整个家庭环境下大屏的核心位置外,单就电视正常观看运行的流程而言,8K电视只解决了最后一个显示器的问题,在这之前还有摄、编、存、播等多个环节。换言之,8K已不再是一项技术,而是依托技术存在的一个系统,除了电视机本身外,以内容为核心的片源、以网络宽带为核心的传输,以及以电视影像处理为核心的芯片等硬件标准缺一不可。现实是,目前尚未看到追逐8K电视的家电企业,能够着力为8K电视解决整个8K系统,都只是单个抛出了并无实际用处的8K电视。

就拿视频的录制和储存来说,据了解,录制20分钟8K超高清视频,就会占用4TB的储存空间,如此大的数据量,如果没有一定的储存设备和处理设备,是不可能做到的。同样,问题也会出现在传输环节,目前传统的电信号传输方式,无法支持8K画面的传输,若要改造传输缆线,这更是一个浩大的工程,不仅仅费用极高,并且也不是一朝一夕所能完成的。而更为关键的是内容,当前4K内容极其匮乏,更遑论8K内容了,所以综合看来,无论是前期的拍摄、影片存储、后期制作、影院播放,都需要专门的8K设备,可目前能够生产8K放映机的厂商却是寥寥无几。

即使上述问题都得到了解决,仍然还存在一个非常尴尬的问题就是,目前很多地区是无法实现4K直播的,更遑论看到使用8K技术转播的2020年东京奥运会呢?除此之外,在生产成本上,8K电视机动辄几十万甚至上百万的价格也会让很多人望而却步。

一个系统的硬件设施跟不上,一项技术的成本过高,一个全新产品的用户教育时间过短,等诸多的因素导致即便突破了某个关键技术,但依然无法改写行业格局的现实。技术的价值,不仅仅在技术层面实现了超越,更多在于技术创造了多少社会效应,这其中最为核心的是整个产业达到技术驱动时代前行的地步。而整个产业与技术能否产生化学反应的考量,在于大众对技术的自有需求和社会环境催化。只有大众对技术有基本需求,技术足够成熟满足盈利条件,与此同时技术的生产成本下降,与之配套整体产业链让大众对技术有接触能力和接触想象空间,这些条件同时成立的时候,创新才能真正进入大众视野,得以进一步提升和普及。

更为通俗的讲,8K技术只有形成业务流程“链”,才能与整个行业、社会“网”对接,并且能够编制出家电的互联“网”。若8K技术只是一座在电视显示领域的金字塔,那么始终无法被互联“网”所接纳。所以,一个8K时代的到来,不是一台8K电视的问世,而需要一套8K全产业链生态系统的创造。
