摘要： Input signals in floating-point format are converted into output signals in integer format while handling saturation cases appropriately. Saturation exists when the value of an input signal is outside the output range. Saturation cases are detected by invoking an integer comparison instruction using signals in floating-point format as inputs to tile integer comparison instruction. When implemented in software on processors such as the Intel.RTM. Pentium.TM. processor, using an integer comparison instruction to compare signals in floating-point format provides more efficient signal conversion than conventional schemes that use a floating-point comparison instruction to compare floating-point signals.
摘要翻译：浮点格式的输入信号将以整数格式转换为输出信号，同时适当地处理饱和情况。当输入信号的值超出输出范围时，存在饱和度。通过使用浮点格式的信号调用整数比较指令作为平铺整数比较指令的输入来检测饱和情况。当在诸如Intel TM Pentium TM处理器的处理器上的软件中实现时，使用整数比较指令来比较浮点格式的信号提供比使用浮点比较指令来比较浮点信号的传统方案更有效的信号转换。

摘要： A system and method is provided for encoding data wherein contiguous data values represent a video image. Three contiguous data values are applied to a loop filter to provide digital filtering of the data values. A frame differencing device performs a subtraction operation upon one of the three contiguous data values simultaneously with the performance of a filtering operation upon another one of the three contiguous data values. Additionally, a discrete cosine transform device performs transform operations upon the third contiguous data value simultaneously with the performance of the digital filtering and the frame differencing operation upon the other two contiguous data values. Because the loop filter is a multipass device the frame differencing device and the discrete cosine transform device must wait while some filtering operations are performed. As soon as one of the contiguous values is applied to the output of the digital filtering device it is operated upon by the frame differencing device. When the frame differencing device is done with this value the discrete cosine transform device begins operating upon the output of the frame differencing device and the frame differencing device operates on the next contiguous data value from the loop filter. A discrete cosine transform system is provided for performing discrete cosine transforms on matrices of input video data.
摘要翻译：提供了一种用于编码数据的系统和方法，其中连续数据值表示视频图像。将三个连续的数据值应用于环路滤波器以提供数据值的数字滤波。帧差分装置对三个相邻数据值中的一个同时执行对三个相邻数据值中的另一个执行滤波操作的减法运算。此外，离散余弦变换装置在与其他两个相邻数据值的数字滤波和帧差分操作的执行同时对第三连续数据值执行变换操作。由于环路滤波器是多通道设备，因此执行一些滤波操作时，帧差分装置和离散余弦变换装置必须等待。一旦连续值中的一个应用于数字滤波装置的输出，它就被帧差分装置操作。当帧差分装置用该值完成时，离散余弦变换装置开始在帧差分装置的输出上运行，并且帧差分装置对来自环路滤波器的下一个连续的数据值进行操作。提供离散余弦变换系统，用于对输入视频数据的矩阵执行离散余弦变换。

摘要： A local subsampled color video signal is converted directly to a CLUT 8 format for local display as a preview image without being locally compressed and decompressed, while the same signal to be transmitted to a remote locate is compressed. The local preview display is thus generated using relatively little computer time and hardware, while still being of adequate quality for preview purposes.

摘要： A method and apparatus for scalably decoding a sequence of encoded digital video frames with a digital processor. A frame discard interval is determined in accordance with the processing power of the digital processor and a counter is initialized. A frame is selected from the sequence for decoding. The selected frame is decoded and the counter is incremented. If the counter is less than the discard interval then the process is repeated; otherwise, at least one subsequent frame from the sequence is replaced with a sync frame which is thereafter decoded.
