炫龙卡资料及参数

高清晰、高保真的数字音视频已伴随着DVD的到来而全面深入我们的生活，以DivX为代表的低容量高质量的MPEG4视频格式的诞生更是给人们带来惊喜。而作为电脑用户，并不愿意在仅仅十几英寸见方的显示器上观赏这类节目。而且，尽管软件解压技术已日臻成熟．但实际的解压效果还是不如硬件解压设备，这也是时至今日视频解压卡仍在市场中存在的原因之一。这里我们将要为大家介绍来自Sigma Designs公司的全能视频解压输出卡--- REALmagic EM8475。

    炫龙卡的最大亮点就在于它能对即将到来的HDTV电视提供全面的支持，独特的YPrPb色差分量端子视频输出能满足从480i(隔行)到1080p(逐行)清晰度的HDTV电视。如果配上DVD视盘和逐行扫描电视机，用户还可通过炫龙卡真正享受到逐行扫描DVD视频的高清晰乐趣。而且若对模拟输出的音效和电脑音箱不满意，还可以通过炫龙卡的SPD怖音频输出接口将Dobly Digital和DTS环绕声音效输出到专门的解码器上以营造出更为震撼的声场。由于模拟和数字音频输出共用一个接口，在主程序Xmedia player中就可以完成两种模式之间的相互转换

炫龙卡开创了一个视频解压卡整合的时代，不仅如此，YPrPb分量端子视频信号的输出再加上对HDTV的完善支持，相信炫龙卡必将成为新一代的KTV视频点播及家庭娱乐中心的最佳产品
