    Abstract: The system carries out conversion of digital video signals organized in blocks of pixels from a first format (10, 30) to a second format (15, 25). The second format is a format compressed via vector quantization (13, 27). The vector quantization is performed by means of repeated application of a scalar quantizer to the pixels of said blocks with a quantization step (Q) determined in an adaptive way according to the characteristics of sharpness and/or brightness of the pixels.

    Abstract translation: 该过程涉及通过标量量化的与量化步长(Q)确定开采在自适应方式gemäß于像素的锐度和/或亮度的特性块的像素重复应用执行向量量化。 量化步长被确定开采增加gemäß缺乏在块中的像素的均匀性。 因此独立权利要求中包括了以下内容:(a)一种系统,用于将两种格式之间的像素的块构成的数字视频信号(b)的计算机程序产品可直接加载到数字计算机的内存和包括软件代码部分用于实现 在像素块变换的数字视频信号为有组织两种格式之间的处理。
