影碟机从VCD发展到超级VCD,使图像的水平清晰度增加了近100线,从260线提升到350线;而音频方面除了增加了两个声道外,并没有多大的变化,因此,其“超级”主要在于视频方面。 美国斯高柏(C-Cube)公司在研制数字视频解压芯片方面一直处于领先地位,最近,在其推出的第三代MPEG-2A/V高素质解压芯片CL 8830中,应用了Real-sonic技术,可恢超级VCD在音频方面具有前所未有的优秀表现。 Realsonic技术是一项全新的数字音频处理技术,其处理速度高达50MIPS。斯高柏公司首次在一片CL8830超级VCD解压芯片上同时集合了数字声场处理(DSP)、数字均衡处理(DEP)和数字卡拉OK处理(DKP)等数字音频处理电路。该芯片除了使超级VCD的视频图像具有高素质、强纠错外,还可使普通的双声道电视或一对音箱发出三维音场的立体声,以及音乐厅、教堂、体育馆等多种音响模式的音响效果;还有数字化图示均衡器,可随意调整频率响应曲线的形状,以获取最佳的音响效果;
VCD player developed from VCD to Super VCD, so that the horizontal resolution of the image increased by nearly 100 lines, from 260 lines to 350 lines; and audio except for the addition of two channels, and not much change, so its “Super” mainly lies in the video. C-Cube, a US company, has been at the forefront of developing digital video decompression chips. Recently, Real-sonic technology was introduced in its CL 8830, the third generation MPEG-2A / V high-quality decompression chip , Can restore super VCD in the audio with unprecedented performance. Realsonic technology is a new digital audio processing technology that processes at up to 50 MIPS. For the first time, the company has integrated digital audio processing circuits such as Digital Sound Processing (DSP), Digital Equalization (DEP) and Digital Karaoke Processing (DKP) on a CL8830 Super VCD decompression chip. The chip in addition to the Super VCD video images with high quality, strong error correction, but also can make ordinary two-channel television or a pair of speakers three-dimensional sound field stereo, as well as concert halls, churches, stadiums and other audio mode Of the sound effects; There are digital graphic equalizer, the shape of the frequency response curve can be adjusted to get the best sound effects;
