DD5.1-EX和DTS-ESDD5.1和DTS分属不同制作格式,两种标准多年以来也一直较劲。其实DD5.1-EX和DTS-ES是双方公司分别于1998年和1999年推出的数位多声道压缩格式,将原来的5.1声道格式推入到了6.1声道格式时代。需要注意的是DTS-ES实际上包含两种:一种是DTS-EsEstendedmatrix另一种是DTS-ESDiscrete6.1。从基本架构的角度看,DD5.1-EX和DTS-ESEstendedmatrix类似,在压缩编码时,以5.1个独立数位讯号加一个中置声道,这个中置声道实际上并不独立,是以一个用类比矩阵编码技术将后中置声道处理在两个后环绕声道中,因此,它们最多只能是5.1基础上的6.1声道。与此种技术不同,
DD5.1-EX and DTS-ESDD5.1 and DTS belong to different production formats, both standards have been competing over the years. In fact, DD5.1-EX and DTS-ES are the digital multichannel compression formats that were released by the two companies in 1998 and 1999, respectively, pushing the original 5.1-channel format into the 6.1-channel format era. It should be noted that DTS-ES actually contains two types: one is DTS-EsEstendedmatrix and the other is DTS-ESDiscrete6.1. From a basic architecture point of view, DD5.1-EX is similar to DTS-ESEstendedmatrix, with 5.1 independent digital signals plus a center channel during compression encoding. The center channel is not really independent, With analog matrix coding, the post-center channel is processed in two back-surround channels, so they can only be up to 5.1 channels at 5.1-based maximum. Different from this kind of technology,
