    摘要： A moving picture encoding apparatus divides a moving picture signal into key frames and non-key frames, encodes the key frames, predicts the non-key frames from the encoded key frames, determines an encoding rate for each non-key frame, encodes each non-key frame, and outputs an error-correcting code at the encoding rate as encoded data of the non-key frame. To determine the encoding rate, parameters related to the likelihood of prediction errors are calculated by at least two different methods for each non-key frame, the parameters are compared, one of the parameters is selected, and the encoding rate is calculated from the selected parameter. The selective use of differently calculated parameters enables an efficient encoding rate to be calculated for each non-key frame and reduces the transmission of encoded data that the decoder does not need or cannot decode.

    摘要： A video encoder apparatus using a distributed video coding (DVC) includes a Wyner-Ziv frame encoder for forming a predictive image of a Wyner-Ziv frame on the basis of coded key frames, and determining, according to the fallibility of the transform coefficients of the predictive image with respect to the transform coefficients of an original image based on the Wyner-Ziv frame, the amount of error correction codes to be transmitted so as to transmit the error correction codes corresponding to the determined amount. When no errors are found between the transform coefficients of the original image of the Wyner-Ziv frame and the predictive image, information indicating that no errors are found is sent out instead of the error correction codes for the Wyner-Ziv frame in question.

    摘要： To code the current frame of a moving picture, a weighting coefficient and the mean pixel values in the current frame and a reference frame are obtained. The weighting coefficient is used to modify the mean pixel value in the reference frame, and an offset value is calculated from the resulting modified mean pixel value and the mean pixel value in the current frame. Reference image blocks are then selected from the reference frame, and a predicted image block is generated by applying the weighting coefficient and the offset value to each selected reference image block. Because of the modification of the mean pixel value of the reference frame, pixel values in the predicted image blocks are distributed around the mean pixel value in the current frame, which leads to efficient coding.

    摘要： A moving picture encoding apparatus divides a moving picture signal into key frames and non-key frames, encodes the key frames, predicts the non-key frames from the encoded key frames, determines a final encoding rate for each non-key frame, encodes each non-key frame, and outputs an error-correcting code at the final encoding rate as encoded data of the non-key frame. To determine the final encoding rate, the number of error-correcting bits needed to correct prediction errors is estimated by a first method and one or more second methods. The second methods are used to decide whether to use the number of bits estimated by the first method as the final encoding rate, or whether to supplement the estimated number of bits by adding an encoding rate correction. As a result, the encoding rate is not supplemented unnecessarily and the encoding efficiency is improved.
