摘要： An image-coding format converting apparatus comprising an EMPEG2 image decoder 30, a resolution/frame rate converter 31, a motion vector converter 32, and an MPEG4 encoder 33. The EMPEG2 decoder 30 decodes a bit stream of EMPEG2 image codes, generating an image signal. The resolution/frame rate converter 31 converts the image signal. The MPEG4 encoder 33 encodes the output of the resolution/frame rate converter 31, generating a bit stream of MPEG4 image codes. In the resolution/frame rate converter 31, pixels are added or extracted in accordance with the start position of a macro block, thus adjusting the input image signal to one than can easily be encoded to MPEG4 image codes. The motion vector converter 32 generates an MPEG4 motion vector from parameters such as an MPEG2 motion vector. The MPEG4 encoder 33 uses the MPEG4 motion vector to encode the output of the resolution/frame rate converter 31.

摘要： An image data converting apparatus comprising an MPEG2-image data decoding section 19, a scan-converting section 20, an MPEG4-image encoding section 21, and a picture-type determining section 18. The MPEG2-image data decoding section 19 decodes input MPEG2-image compressed data in both the vertical direction and the horizontal direction by using only lower, fourth-order coefficients. The scan-converting section 20 converts interlaced-scan pixel data to sequential-scan pixel data. The MPEG4-image encoding section 21 generates MPEG4-image compressed data from the sequential-scan pixel signals. The sections 19, 20 and 21 are connected in series. The picture-type determining section 18 is connected to the input of the MPEG2-image data decoding section 19. The section 18 determines the picture type of each frame data contained in the interlaced-scan MPEG4-picture compressed data, outputs only the frame data about I/P pictures, discards the frame data about B pictures, thereby converting the frame rate.
