摘要： A system, method, and apparatus for reducing the video decoder processing requirements are presented herein. During a rewind operation, a reference picture for a group of pictures is decoded and stored into a reference frame buffer. By storing a reference picture for the group, the reference picture need not be decoded to display each picture in the group during the rewind operation.

摘要： Schemes for rewinding a HITS stream in video recorder and playback systems are presented herein. Reference pictures are stored for a group of pictures, allowing subsequent pictures to be decoded from the reference pictures. The foregoing significantly reduces the number of picture decodes required to display a HITS stream in reverse order.

摘要： Presented herein are systems, methods, and apparatus for improving performance of video decoders during rewind and fast forward operation. Video decoder performance is improved by avoiding repetitive decoding of prediction pictures. When a decoded prediction picture is stored in a frame buffer, techniques are presented for decoding multiple pictures in the rewind order which are dependent thereon, displaying the picture directly from the frame buffer, and setting one type of prediction picture as another type of prediction picture.

摘要： A method is presented for marking high-quality digital images with a robust and invisible watermark. It requires the mark to survive and remain detectable and authenticatable through all image manipulations that in themselves do not damage the image beyond useability. These manipulations include JPEG “lossy” compression and, in the extreme, the printing and rescanning of the image. The watermark also has the property that it can detect if the essential contents of the image has changed. The first phase of the method comprises extracting a digest or number N from the image so that N only (or mostly) depends on the essential information content, such that the same number N can be obtained from a scan of a high quality print of the image, from the compressed form of the image, or in general, from the image after minor modifications (introduced inadvertently by processing, noise etc.). The second phase comprises the marking. This can be done in form of an invisible robust watermark, or in form of some visible signature or watermark.
摘要翻译： 提出了一种用强大且不可见的水印标记高质量数字图像的方法。 它需要标记生存，并通过所有图像操作保持可检测和可认证，这本身不会损害图像超出可用性。 这些操作包括JPEG“有损”压缩，在极端情况下，打印和重新扫描图像。 该水印还具有可以检测图像的基本内容是否已改变的属性。 该方法的第一阶段包括从图像中提取摘要或数字N，使得仅N（或主要地）取决于基本信息内容，使得可以从扫描的高质量打印获得相同数量N 图像，从图像的压缩形式，或一般来说，从稍后修改的图像（通过处理，噪声等无意中引入）。 第二阶段包括标记。 这可以以不可见的鲁棒水印的形式或以一些可见的签名或水印的形式来完成。
