    • A digital video signal processing system receives encoded packets of data representing video image information in compressed form. A video decoder and an associated video RAM are used to decode and decompress the video packets to form groups of video image representative digital words. The video image groups are organized in a compressed component format (e.g., Y, U, V in the ratio 4:2:2) related to the video image compression format in which pairs of color related components correspond to more than one pixel. The video decoder also includes an on-screen display (OSD) unit which converts a graphics bit map stored in a section of the video RAM to groups of graphic image representative digital words. The graphic image groups are organized in an uncompressed component format (Y, U, V in the ratio 4:4:4). Color related components of the uncompressed graphic image groups are deleted by a converter so as to form new graphic image groups having the same format as the video image groups which may be readily multiplexed with the video image groups to insert a graphics image within a video image.
    • 数字视频信号处理系统以压缩形式接收表示视频图像信息的编码数据分组。 视频解码器和相关联的视频RAM用于解码和解压缩视频分组以形成视频图像代表性数字字组。 视频图像组以与多于一个像素对应的视频图像压缩格式相关的压缩分量格式(例如,比例为4:2:2的Y,U,V)被组织。 视频解码器还包括屏幕显示(OSD)单元,其将存储在视频RAM的一部分中的图形位图转换成图形图像代表数字字的组。 图形图像组以未压缩的组件格式(Y,U,V,比例为4:4:4)组织。 通过转换器删除未压缩的图形图像组的颜色相关的组件,以形成具有与视频图像组容易复用的视频图像组相同格式的新的图形图像组,以在视频图像内插入图形图像 。

    • A variable length decoder including the cascade combination of a buffer memory for providing parallel-bit coded data in N-bit bytes, and a first barrel shifter having an R-bit input port and an R-bit output port (R>N). The R-bit output port of the first barrel shifter is coupled to respective first inputs of a bank of R two-input OR gates. The outputs of the OR gates are coupled to the parallel input of a register or latch, the output of which is coupled to the address input port of a lookup table for providing decoded versions of variable length codewords applied to its address port, and providing indicia which indicates the length of respective decoded variable length codewords. The output of the register is also coupled to the input of a second R-bit input R-bit output second barrel shifter. The output of the second barrel shifter is coupled to respective second input connections of said bank of OR gates. The indicia provided by the lookup table are applied to a Shift State Machine, which generates control signals to control the respective bit shift operations of the first and second barrel shifters. The combination of barrel shifters and the OR circuit provide for rapid application of successive variable length codewords to the lookup table.
    • 一种可变长度解码器,包括用于提供N位字节的并行比特编码数据的缓冲存储器的级联组合和具有R位输入端口和R位输出端口(R> N)的第一桶形移位器。 第一桶形移位器的R位输出端口耦合到R个双输入或门组的相应第一输入端。 或门的输出耦合到寄存器或锁存器的并行输入端,寄存器或锁存器的输出端耦合到查找表的地址输入端口,用于提供应用于其地址端口的可变长度码字的解码版本,并提供标记 其指示各个解码的可变长度码字的长度。 寄存器的输出也耦合到第二R位输入R位输出第二桶形移位器的输入端。 第二桶形移位器的输出耦合到所述OR门组的相应的第二输入连接。 由查找表提供的标记被应用于移位状态机,该移位状态机产生控制信号以控制第一和第二桶形移位器的相应位移操作。 桶形移位器和OR电路的组合提供连续可变长度码字到查找表的快速应用。

    • A tool storage container has a base member with a tool receiving member. A cover is coupled with the base. An opening is in the cover. The opening may have a configuration corresponding to the tool maintained within the carrying case or any other configuration which enables viewing and prohibits removal of the tool when the container is in a closed position. A plurality of storage areas are within the inside of the cover. Also, fingers secure the tool in the carrying case so that in an open condition, the tool is maintained in the carrier.

    • A protective overshoe which reduces the risk of injury from industrial impact, compression, chemical, puncture, and electrical hazards and simultaneously protects both a foot and a street shoe worn by the foot. The overshoe may include a protective sole, a protective upper, and a toe box. The protective sole is made with conventional materials such as butyl rubber, neoprene rubber, polyvinyl chloride, nitrile, and combinations thereof. An optional puncture guard in the sole protects against punctures. The protective upper is large enough to substantially cover the upper of the street shoe. Protective uppers are made of the same or similar materials as those used in the protective soles. The toe box, which substantially covers and protects the user's toes, is formed of a conventional rigid material such as steel, rigid plastic, or fiberglass. The overshoe may also include a metatarsal guard, an upper which extends up along the user's calf, or a strap for tightening the overshoe about the street shoe.
