精彩的影音世界永远都不会缺乏超前的技术支持,继上期针对4K2K升频与2D转3D处理这两个目前最火热的视频处理技术进行深入浅出的剖析之后,本期将围绕激光背光光源与环绕声三维音效处理两种最热门的影音技术进行分析,希望能够找到未来影音市场发展的重要之道。这两种影音技术分别针对不同的应用层面,激光背光光源属于视频类,多声道音效处理属于音频类。其实,这两种新技术都不是现在才面世的,而是经过长年的研究与发展才逐渐迈向成熟,证明它们的效果已经获得市场的广泛认可。尤其是多声道音效处理技术,已经慢慢渗透入AV放大器与耳机领域。而激光技术对于国人来说都并不陌生,早在数十年前就已经出现,并广泛应用在军事、医学、教育以及商用等领域。在家庭影音领域,一直以来都有许多厂商希望能够将激光技术应用在显示设备之中,以解决传统光源存在的各种亮度与色彩方面的问题。但是由于激光具有不同于普通光线的特殊光学特性,很难应用在直射式显示设备之中。不过在近两年,分别有不同的民用厂商将激光技术应用在消费级别显示设备的背光光源部分,解决了传统高压水银灯以及LED光源存在的各种不足之处。
Wonderful audio and video world will never lack of advanced technical support, following the previous period for 4K2K up-conversion and 2D to 3D processing, the two hottest video processing technology to explain profound theories in simple language, this issue will focus on laser backlight and surround Acoustic three-dimensional sound effects processing two of the most popular video technology analysis, hoping to find the future development of audio and video market, an important way. The two audio and video technologies are applied to different application levels, the laser backlight light source is a video class, multi-channel audio processing belongs to the audio class. In fact, these two new technologies are not available now, but only gradually mature after years of research and development, proving their effectiveness has been widely recognized by the market. In particular, multi-channel audio processing technology, has slowly penetrated into the field of AV amplifiers and headphones. Laser technology, however, is no stranger to people in the country, as early as decades ago, and has been widely used in military, medical, educational and commercial fields. In the field of home audio and video, many manufacturers have been hoping to apply laser technology to display devices to solve various brightness and color problems of traditional light sources. However, due to the special optical characteristics of lasers that are different from ordinary light, it is very difficult to apply them in direct display devices. However, in the past two years, different domestic manufacturers have applied laser technology to the backlight source of consumer-level display devices to solve the various shortcomings of traditional high-pressure mercury lamps and LED light sources.
