    摘要： Electronic devices for de-quantization are disclosed. An electronic device includes at least a multiplier. The multiplier generates a de-quantization scale by multiplying a first sub-factor by a second sub-factor after acquiring a macro-block (MB) from a bitstream. The generated de-quantization scale enables de-quantization of a block of the MB. Another electronic device includes at least a multiplier. The multiplier generates a quantization scale by multiplying the inverse of a first sub-factor by the inverse of a second sub-factor after acquiring an MB from a video sequence. The generated quantization scale enables quantization of a block of the MB.

    摘要： For processing, e.g. encoding or decoding, a video stream, a type of a current macroblock unit is determined. The type indicates portions of corresponding macroblock parameter sets necessary for processing the current macroblock unit. The corresponding macroblock parameters are mapping to a dependent set of macroblock units of the current macroblock unit. The current macroblock unit is processed if a local buffer already stores the portions of the corresponding macroblock parameter sets. If data of the portions of the corresponding macroblock parameter sets that are not available in the local buffer, the data are copied from a memory circuit into the local buffer for processing the macroblock unit.

    摘要： A progressively encoded image file, e.g. a JPEG bit stream, is decoded in multiple rounds. In first round, variable length encoded data in multiple scan segments of a first region are decoded. Meanwhile, position indicators for locating the next region are stored. In next round, the second region is decoded by reference to the position indicators for locating where the variable length encoded data of the second region are stored. The procedures are repeated until all regions are decoded to save memory usage during decoding.
