重点:VCD机是影音信号源播放设备,因此,图像和声音的质量是购机时首先应注意的问题。虽然VCD图像因信号压缩和数码率的限制,活动图像的分辨率只能达到250线,但因解压芯片不同和整机设计、工艺加工上的差异,图像质量也是有区别的。如经常用VCD机唱卡拉OK,则对卡拉OK音效和相应功能也要重点考虑。
Focus: VCD machine is a video signal source playback equipment, therefore, the quality of images and sound is the first purchase should pay attention to the problem. Although VCD images due to signal compression and digital rate limit, the resolution of active images can only reach 250 lines, but due to different decompression chip and machine design, process differences, image quality is also different. Such as the frequent use of VCD karaoke karaoke OK, the karaoke OK sound effects and the corresponding features should also be considered.
