    • A method is claimed for encoding a group of pictures at a target bit rate. A pre-analysis procedure (105) is performed for each from in the group of pictures as to develop a series of parameters. A pre-processing procedure is then performed for a frame selected from said group of pictures (115), so that the parameters associated with the selected frame are updated while the parameters associated uuencoded frames from the group of pictures remain the same. These two sets of parameters are then used to determine an allocated bit rate (125) for the frame such that when the frame is actually encoded, the allocated bit rate is reserved for the encoding operation. The allocated bit rate and the target bit rate for the group of pictures may be different, and the quantization level associated with the allocated bit rate may be different than the quantization level associated with the actual bit rate used to encode the frame.
    • 要求一种用于以目标比特率对一组图像进行编码的方法。 对于图像组中的每一个执行预分析过程(105)以形成一系列参数。 然后对从所述图像组(115)中选择的帧执行预处理过程,使得与所选择的帧相关联的参数被更新,同时来自所述图像组的相关联的编码的帧的参数保持不变。 然后使用这两组参数来确定用于该帧的分配的比特率(125),使得当该帧被实际编码时,分配的比特率被保留用于编码操作。 图像组的分配比特率和目标比特率可以不同,并且与分配的比特率相关联的量化级别可能不同于与用于编码帧的实际比特率相关联的量化级别。

    • Organocatalysts, particularly proline sulfonamide organocatalysts, having a first general formula as follows are disclosed. Embodiments of a method for using these organocatalysts also are disclosed. The method comprises providing a disclosed organocatalyst, and performing a reaction, often an enantioselective or diastereoselective reaction, using the organocatalyst. Solely by way of example, disclosed catalysts can be used to perform aldol reactions, conjugate additions, Michael additions, Robinson annulations, Mannich reactions, a-aminooxylations, a-hydroxyaminations, a-aminations and alkylation reactions. Certain of such reactions are intramolecular cyclizations used to form cyclic compounds, such as 5- or 6-membered rings, having one or more chiral centers. Disclosed organocatalysts generally are much more soluble in typical solvents used for organic synthesis than are known compounds. Moreover, the reaction yield is generally quite good with disclosed compounds, as is their enantioselective and diastereoselective effectiveness.
    • 公开了具有如下第一通式的有机催化剂,特别是脯氨酸磺酰胺有机催化剂。 也公开了使用这些有机催化剂的方法的实施方式。 该方法包括提供公开的有机催化剂,并使用有机催化剂进行反应,通常是对映选择性或非对映选择性反应。 仅举例而言,公开的催化剂可用于进行醛醇缩合反应,缀合物加成,迈克尔加成,罗宾逊环,曼尼希反应,α-氨氧基化,α-羟胺化,α-胺化和烷基化反应。 某些这样的反应是用于形成具有一个或多个手性中心的环状化合物例如5元或6元环的分子内环化。 披露的有机催化剂通常比已知化合物更易溶于用于有机合成的典型溶剂。 此外,所公开的化合物的反应收率通常相当好,它们的对映选择性和非对映选择性效果也是如此。
