    • A video processing apparatus for de-interlacing includes a video decoder and a de-interlacing circuit. The video decoder decodes a video data stream to generate an interlaced video signal and transmits a first interlaced control signal. The de-interlacing circuit is coupled to the video decoder, and includes a detecting unit and an interlacing to progressive converting unit. The detecting unit generates a second interlaced control signal according to the interlaced video signal and the first interlaced control signal. The interlacing to progressive converting unit is coupled to the detecting unit for receiving the interlaced video signal as well as the second interlaced control signal and for converting the interlaced video signal into a first progressive video signal according to the second interlaced control signal.
    • 用于去隔行扫描的视频处理装置包括视频解码器和去隔行电路。 视频解码器解码视频数据流以产生隔行扫描视频信号并发送第一隔行控制信号。 去隔行电路耦合到视频解码器,并且包括检测单元和逐行转换单元的隔行扫描。 检测单元根据隔行视频信号和第一隔行控制信号产生第二隔行控制信号。 与逐行转换单元的隔行耦合到检测单元,用于接收隔行扫描视频信号以及第二隔行控制信号,并根据第二隔行控制信号将隔行视频信号转换成第一逐行视频信号。

    • A source frame signal received at a first frame rate is converted to a destination frame signal output at a second frame rate. By adjusting the clock frequency of the clock signal in the destination frame signal, the second frame rate is made to be the same as the first frame rate. Adjusting the destination clock frequency prevents overflow and underflow conditions. The destination clock frequency is decreased to prevent underflow or increased to prevent overflow. The destination clock frequency during the last horizontal line is adjusted to comply with some display devices having a maximum time constraint from a last horizontal sync signal to a vertical sync signal in the destination frame signal.
    • 以第一帧速率接收的源帧信号被转换为以第二帧速率输出的目的地帧信号。 通过调整目的地帧信号中的时钟信号的时钟频率,使第二帧速率与第一帧速率相同。 调整目标时钟频率可以防止溢出和下溢条件。 目的地时钟频率降低以防止下溢或增加以防止溢出。 调整最后水平行期间的目的地时钟频率以符合从目标帧信号中的最后水平同步信号到垂直同步信号具有最大时间约束的一些显示设备。
