A video compression system includes a video encoder and a bitstream processing circuit. The video encoder is hardware that performs hardware video encoding upon frames to generate a first bitstream. The first bitstream is output from an entropy encoding circuit of the video encoder. The bitstream processing circuit performs a bitstream post-processing operation upon the first bitstream to produce a second bitstream that is different from the first bitstream, and outputs the second bitstream as a compression output of the frames.

A video encoder has a processing circuit and a universal binary entropy (UBE) syntax encoder. The processing circuit processes pixel data of a video frame to generate encoding-related data, wherein the encoding-related data comprise at least quantized transform coefficients. The UBE syntax encoder processes a plurality of syntax elements to generate UBE syntax data. The encoding-related data are represented by the syntax elements. The processing circuit operates according to a video coding standard. The video coding standard supports arithmetic encoding. The UBE syntax data contain no arithmetic-encoded syntax data.

A scanner has a hollow base, a bracket securely received in the hollow base and having a paper-pressing bar mounted onto the bracket, a top seat securely provided to one side of the hollow base and a top cover mounted on top of the top seat. The top cover has a pressing plate extending into an interior of the top seat and a pair of pressers each extending to engage with and abut the paper-pressing bar. The paper-pressing bar has a driven gear mounted on one distal end thereof so as to correspond to a driving gear of the bracket and a rubber sleeve mounted on the paper-pressing bar to increase a friction. The paper-pressing bar is releasably mounted on a pair of cutouts in the bracket so that the paper-pressing bar is able to move vertically relative to the bracket.
