    • A method of transmitting video data includes receiving a frame of video data of a first resolution from an image capture device at a video transmission device and generating interlaced fields of the frame of video data at the video transmission device by applying a filter with a different set of filter coefficients to at least one field than is applied at least one other field. A method of producing video data of a particular resolution includes generating estimated high resolution video data from low resolution video data received at a display device, producing estimated low resolution video data from the estimated high resolution video data by applying a filter to the estimated high resolution video data, differencing the estimated low resolution video data and the received low resolution video data to generate difference data, and using the difference data to generate new estimated high resolution video data.
    • 一种发送视频数据的方法包括:从视频传输装置的图像捕获装置接收第一分辨率的视频数据帧,并通过应用具有不同集合的滤波器在视频传输装置处产生视频数据帧的隔行扫描场 的滤波器系数至少应用至少一个其他场的场。 一种产生特定分辨率的视频数据的方法包括从在显示装置处接收的低分辨率视频数据产生估计的高分辨率视频数据,通过将估计的高分辨率应用滤波器从所估计的高分辨率视频数据产生估计的低分辨率视频数据 视频数据,差分估计的低分辨率视频数据和接收到的低分辨率视频数据,以产生差分数据,并使用差分数据生成新的估计的高分辨率视频数据。

    • The present invention provides a method and apparatus for the correction of time base errors in a video signal. The method and apparatus may combine a horizontal scaler and a time base corrector. A time base corrector in accordance with the present invention can function without locking a clock to a horizontal synchronization signal. Furthermore, a method or apparatus in accordance with the present invention may operate as a finite impulse response filter, an infinite impulse response filter, a low pass filter or an adaptive filter.
    • 本发明提供了一种用于校正视频信号中的时基误差的方法和装置。 该方法和装置可以组合水平缩放器和时基校正器。 根据本发明的时基校正器可以在不将时钟锁定到水平同步信号的情况下起作用。 此外,根据本发明的方法或装置可以作为有限脉冲响应滤波器,无限脉冲响应滤波器,低通滤波器或自适应滤波器来操作。
