    摘要： A method and apparatus for controlling the rate of compression in video/image compression environments is provided. The method includes determining a scaling factor that results in a compressed file size as close to a target file size as possible. In determining the scaling factor, tolerance limits of the current file size as compared with a predetermined tolerance is made, and when the tolerance is not met, the current scaling factor is interpolated to generate a new scaling factor, and consideration of a ratio of file sizes is made to determine if a new down-sampling factor is needed for the interpolated scaling factor.

    摘要： An emulation prevention byte remover may include one or more of a first buffer, a second buffer, a checker, and a shifter. The first buffer may store first stream data. The second buffer may store second stream data. The checker may determine whether one or more emulation prevention bytes are included in the first, second, or first and second stream data. If the checker determines that the one or more emulation prevention bytes are included in the first, second, or first and second stream data, the checker may output a check signal. In response to the check signal, the shifter may remove at least one of the one or more emulation prevention bytes from the first, second, or first and second stream data. The shifter may generate output stream data based on the first, second, or first and second stream data.

    摘要： A video processing device includes a video preprocessor and a video processor. The video processor is configured to facilitate inputting preprocessed digital video data ready for further processing by an encoder or a transcoder, compressing the preprocessed digital video data to form compressed digital video data, and outputting the compressed digital video data. The video preprocessor operable to receive digital video raw data, configured to facilitate preprocessing a macroblock of the digital video raw data so as to output the preprocessed digital video data ready for an encoder or transcoder of the video processor when the macroblock does not indicate SKIP, and not preprocessing the macroblock of the digital video raw data when the macroblock is a SKIP macroblock indicating SKIP, but jumping to process the SKIP macroblock by an entropy encoder of the video processor instead.

    摘要： An information processing apparatus that generates images for displaying a computer execution result on a display unit of a terminal device connected through a network and that transmits the images to the terminal device. The apparatus includes an image memory that holds the images; a first transmitting unit that transmits the images, a detecting unit that detects an area obtained by updating accumulated changes between frames of the images or a frequency of changes between frames of the images, and a second transmitting unit that compresses the images by a compression method and that transmits the compressed images, when the area or the frequency detected by the detecting unit is larger than or equal to a predetermined threshold, the compression method being different from a compression method for the first transmitting unit.
