摘要： A method and apparatus for displaying an image in a system having an image generation subsystem and an image display subsystem. The image generation subsystem is provided information regarding image display subsystem capabilities (i.e., image color formats and data transfer modes). The image generation subsystem generates for display test images based on permutations of those capabilities and generates image color priority lists based on the display results. The image generation subsystem is then provided digital data and image display parameters corresponding to the image. The image generation subsystem selects an image color format and a data transfer mode for the image based on the priority lists and the image display parameters, and then processes the image for display using the selected image color format and data transfer mode. The image display subsystem then displays the image.

摘要： Image data to be processed multiple times for display is encoded to provide faster display processing. For example, an original image having pixels that may be either transparent or non-transparent may be displayed multiple times within a single display and/or over successive displays. Rather than having to determine pixel transparency on a pixel-by-pixel basis each and every time the image is to be processed for display, the original image is encoded to generate an encoded image. The encoding process involves grouping the original image pixels into sets and characterizing the transparencies of the pixels of each set. A code signal representing the results of the characterization of each set of pixels is then encoded into the encoded image, along with the original image pixels. Each time the original image data is to be processed for display, the encoded image rather than the original image is used as input to special transparency decode processing. During decode processing, the code signals are retrieved from the encoded image and used to determine how to display the corresponding sets of pixels which are also retrieved from the encoded image. In this way, the original image data can be processed for display multiple times without having to perform pixel transparency analysis, one pixel at a time, each time the image is displayed.
摘要翻译：要进行多次显示的图像数据被编码以提供更快的显示处理。例如，具有可以是透明或不透明的像素的原始图像可以在单个显示器内和/或在连续显示器上多次显示。每一次图像要被处理以进行显示时，不必一个像素地确定像素透明度，而是对原始图像进行编码以生成编码图像。编码过程包括将原始图像像素组合成组并表征每组像素的透明度。表示每组像素的表征结果的代码信号随着原始图像像素被编码到编码图像中。每次要处理原始图像数据以进行显示时，编码图像而不是原始图像被用作特殊透明度解码处理的输入。在解码处理期间，从编码图像中检索代码信号，并用于确定如何显示也从编码图像中检索的相应的像素组。这样，每次显示图像时，原始图像数据可以被多次处理，而无需执行像素透明度分析，一次一个像素。

摘要： In a method and apparatus for decompressing a digital video signal representative of an input sequence of digital video frames, a digital video signal is provided to a video decompressor having a target frame decompression rate which is initially set at the maximum possible frame rate. The output of the video decompressor is monitored to determine whether the video decompressor is timely generating the output sequence of digital video frames. If the video decompressor is not timely generating the output sequence of digital video frames, then the video decompressor output is adjusted by omitting from the output sequence at least one frame from the input sequence. A frames missed value is generated in response to each group of one or more omitted frames, and deviations in the frames missed value are monitored. The target decompression rate of the video decompressor is selectively adjusted downward in response to deviations in the frames missed value.

摘要： A region of an image having a plurality of corresponding image values is encoded to generate a temporary encoded region. The temporary encoded region is then decoded to generate a decoded region. An error measure is generated as a function of the decoded pixels of the decoded region and the previous pixels of a previous region. If the error measure is less than a specified threshold, then the region is encoded as a skipped region, otherwise the region is encoded as the temporary encoded region.
