A method and system for minimizing bus traffic in a video decoder is disclosed. A method and system for processing a portion of a reference picture includes designating the reference picture, selecting a display picture within the reference picture, transmitting a display picture size, and sending a display picture offset. A method and system for compressing IDCT coefficients corresponding to a macroblock, the macroblock having a plurality of blocks, includes locating each non-zero IDCT coefficient corresponding to one of the plurality of blocks, assigning an index to the non-zero IDCT coefficient, the index designating a location within the one of the plurality of blocks, packing the non-zero IDCT coefficient in little endian format, and specifying a terminator bit corresponding to the non-zero coefficient, the terminator bit indicating the end of all non-zero IDCT coefficients for the one of the plurality of blocks. A method and system for selectively controlling each hardware device within a video decoder includes obtaining a video stream, performing VLC decoding, encoding a plurality of instructions to control each hardware device within the video decoder, decoding each one of the plurality of instructions, and optionally performing an IDCT in response to each one of the plurality of instructions.

436161

A chromatographic method including chromatographically separating sample ionic species in an eluent stream, detecting the separated sample ionic species, catalytically combining hydrogen and oxygen gases or catalytically decomposing hydrogen peroxide in a catalytic gas elimination chamber, and recycling the effluent stream from the chamber to the chromatography separation column. The residence time between the detector and the chamber is at least about one minute. Also, flowing the recycle sequentially through two detector effluent flow channels of an electrolytic membrane suppressor. Also, applying heat or UV energy between the detector and the chamber. Also, detecting bubbles after the chamber. Also, a Platinum group metal catalyst and ion exchange medium in the chamber. Apparatus for performing the methods.
