    摘要： A method and apparatus for digitally encoding video image data, which is particularly suited for encoding Internet Web pages, eliminates the need for performing time consuming, computationally intensive motion vector searches by taking advantage of prior knowledge regarding the Web page movement. In a first preferred embodiment, a digital video encoder, such as an MPEG encoder, employs Web page scrolling coordinates obtained from a browser application to determine, through calculation instead of searching, motion estimation for all the macroblocks of the present image frame relative to the previous frame. In a second preferred embodiment, the encoder receives information from the browser application that indicates that certain portions of an image, such as a Web page animation window, are continuously changing, and thus should be encoded as an intra frame. The invention may be employed in a cable television system which includes Internet access capabilities that permit system users to download Web pages for viewing on their televisions from a remote browser application located in the cable system's headend.

    摘要翻译： 用于数字编码视频图像数据的方法和装置，其特别适用于编码因特网网页，消除了通过利用有关网页移动的现有知识来执行耗时且计算密集的运动矢量搜索的需要。 在第一优选实施例中，诸如MPEG编码器的数字视频编码器采用从浏览器应用获得的网页滚动坐标，以通过计算而不是搜索当前图像帧的所有宏块的运动估计来相对于 前一帧。 在第二优选实施例中，编码器从浏览器应用程序接收指示诸如网页动画窗口的图像的某些部分正在连续变化的信息，因此应该被编码为帧内帧。 本发明可以用在有线电视系统中，该有线电视系统包括允许系统用户从位于电缆系统头端的远程浏览器应用在其电视机上下载网页的因特网接入功能。
