    • A projection apparatus includes an illumination system providing an illumination light beam, a light valve disposed in a transmission path of the illumination light beam and converting the illumination light beam into an image light beam, a projection lens disposed in a transmission path of the image light beam, a first field lens, and a second field lens. The first field lens and the second field lens are disposed between the light valve and the projection lens and in the transmission paths of the illumination light beam and the image light beam. The first field lens is a positive meniscus lens with a first concave surface facing the projection lens. The second field lens is a positive meniscus lens with a second concave surface adjacent to the first field lens. The projection apparatus is capable of reducing a ghost image.
    • 投影装置包括提供照明光束的照明系统,设置在照明光束的传输路径中并将照明光束转换为图像光束的光阀,设置在图像光的传输路径中的投影透镜 光束,第一场透镜和第二场透镜。 第一场透镜和第二场透镜设置在光阀和投影透镜之间以及照明光束和图像光束的传输路径中。 第一场透镜是具有朝向投影透镜的第一凹面的正弯月透镜。 第二场透镜是具有与第一场透镜相邻的第二凹面的正弯月透镜。 投影装置能够减少重影。

    • A method for processing an audio/video bit-stream includes the steps of receiving an input bit-stream, detecting whether the input bit-stream has a startcode emulation prevention pattern, and removing the startcode emulation prevention pattern from the input bit-stream to generate an output bit-stream and setting a flag signal as a first designated flag value when the startcode emulation prevention pattern is detected. The method further includes the step of detecting whether the input bit-stream includes a startcode, and directly outputting the input bit-stream and setting the flag signal as a second designated flag value when the startcode is detected.
    • 一种用于处理音频/视频比特流的方法包括以下步骤:接收输入比特流,检测输入比特流是否具有起始码仿真预防模式,以及将起始码仿真防止模式从输入比特流移除到 当检测到起始码仿真防止模式时,生成输出比特流并将标志信号设置为第一指定标志值。 该方法还包括检测输入比特流是否包括起始码,并且当检测到起始码时直接输出输入比特流并将标志信号设置为第二指定标志值的步骤。
