    • A method and system for minimizing bus traffic in a video decoder is disclosed. A method and system for processing a portion of a reference picture includes designating the reference picture, selecting a display picture within the reference picture, transmitting a display picture size, and sending a display picture offset. A method and system for compressing IDCT coefficients corresponding to a macroblock, the macroblock having a plurality of blocks, includes locating each non-zero IDCT coefficient corresponding to one of the plurality of blocks, assigning an index to the non-zero IDCT coefficient, the index designating a location within the one of the plurality of blocks, packing the non-zero IDCT coefficient in little endian format, and specifying a terminator bit corresponding to the non-zero coefficient, the terminator bit indicating the end of all non-zero IDCT coefficients for the one of the plurality of blocks. A method and system for selectively controlling each hardware device within a video decoder includes obtaining a video stream, performing VLC decoding, encoding a plurality of instructions to control each hardware device within the video decoder, decoding each one of the plurality of instructions, and optionally performing an IDCT in response to each one of the plurality of instructions.

    • A manual controller commands a telescope mount to automatically track a specific bright star after the image of the star is located to center of an electronic eyepiece and a timer is started. The average moving speed of the bright star is calculated after a predetermined elapsed time to acquire the right ascension (RA) and the declination (DEC) coordinates of this bright star. Subsequently, the RA and DEC coordinates are compared with pre-stored data contained within a database used to identify the bright star. The celestial sphere coordinates of the telescope can be determined after a minimum of one bright star is identified. In the auto-tracking procedure, the manual controller controls movement of telescope by feedbacks of the drifting speed and direction of the specific bright star in an electronic eyepiece for the purpose of keeping the specific bright star in the center of the electronic eyepiece.
    • 手动控制器命令望远镜安装座,在星形图像位于电子目镜的中心并启动定时器之后自动跟踪特定的明亮星。 在预定的经过时间之后计算亮星的平均移动速度,以获得该亮星的右上升(RA)和偏角(DEC)坐标。 随后,将RA和DEC坐标与包含在用于识别亮星的数据库中的预存数据进行比较。 望远镜的天球坐标可以在识别出最少的一颗明亮星之后确定。 在自动跟踪过程中,手动控制器通过电子目镜中特定亮星的漂移速度和方向的反馈来控制望远镜的移动,目的是保持电子目镜中心的特定亮星。
