    • Conversion encoding coefficients which are accumulated in an input memory and read out from the memory is input into converting unit. Conversion matrix integration unit multiplies a basis matrix of conversion encoding coefficient by, arbitrary interpolation matrix or thinning matrix which is input from resolution conversion matrix inputting unit and sampling conversion matrix inputting unit to produce a converting matrix, and outputs the same to the converting unit. Alternatively, the conversion matrix integration unit selects a converting matrix which is previously calculated and stored in the memory, and outputs the same to the converting unit. The converting unit inputs the converting matrix from the conversion matrix integration unit and the conversion encoding coefficients from the input memory, and achieves the resolution conversion and sampling conversion by matrix product computation of the conversion encoding coefficients in row unit.
    • 积存在输入存储器中并从存储器读出的转换编码系数被输入到转换单元中。 转换矩阵积分单元将转换编码系数的基矩阵乘以由分辨率转换矩阵输入单元和采样转换矩阵输入单元输入的任意内插矩阵或稀疏矩阵,以产生转换矩阵,并将其输出到转换单元。 或者,转换矩阵积分单元选择预先计算并存储在存储器中的转换矩阵,并将其输出到转换单元。 转换单元从转换矩阵积分单元输入转换矩阵和来自输入存储器的转换编码系数,并通过行单位的转换编码系数的矩阵乘积来实现分辨率转换和采样转换。

    • Input MPEG compressed data is input into a partial decoder and a logo insertion controller. A block DCT coefficients (a) output from the partial decoder is divided into a logo insertion region (c) and a non-logo insertion region (d) in a logo insertion region separator. Logo data (e) supplied from a logo information supply section is combined into the logo insertion region (c) with an arbitrary mixing ratio in a logo information insert section. In a logo region partial re-encoder, intra-frame coding of an image insertion region is executed when a starting frame for inserting an image is an intra-coded frame or a predictive coded frame, and, when the starting frame is a bidirectionally predictive-coded frame, inter-frame coding of the image insertion region is executed, and intra encoding of the image insertion region is executed in a frame to which the starting frame for inserting the image can refer.

    • The picture input section 12 fetches image data from the storage device 11, and then, inputs image data on sequential n images into the section 13 for measuring correlation between sequential images and the section 14 for measuring correlation between sampled images. The section 13 for measuring correlation between sequential images measures the correlation between sequential images based on video data. The section 14 for measuring correlation between sampled images measures the correlation between sub-sampled images. The short shot determining section 15 determines short cut points by using the correlation between the sequential images and the correlation between the sub-sampled images. Otherwise, short cut points may be determined in consideration of motion amount between the sequential images or the sub-sampled images.

    • A next input image selector 8 specifies a time at which an input image to be processed next is to be input immediately after finishing an encoding of one image. An input video capture 1 obtains an image of which input time has been specified and sends this image to an input image information detector 2. The input image information detector 2 makes a decision as to whether or not the input image is an image to be processed based on an image variance between this input image and an input image processed immediately before stored in a frame memory 3. If this decision is negative, an input image re-selector 4 re-selects an image to be processed, and if the decision is affirmative, this input image is sent as an image to be processed to a target output bits setter 5 and a motion predictor 11. An output bits controller 6 determines a quantizing level of a quantizer 14 from target output bits and actual output bits obtained from an encoder 15. A video encoder capable of encoding images in uniform picture quality with realtime processing feature can be provided.
