摘要： An apparatus by which a user can easily set a parameter for conversion when a compression encoding system of video stream is converted is provided. A particular period in a first video stream is repeatedly reproduced to convert the reproduced portion into a second video stream in real time. At that time, the user checks the image quality after conversion on a preview screen and sets a desired conversion parameter. A local decode image is output to the preview screen. Thus, the circuit configuration is simplified.

摘要： In a transcoder that decodes and encodes a motion picture stream, a highly compressed motion picture stream cannot be obtained if the same corresponding frame is referenced for coding purposes in a situation where an intraframe coding mode, in which an unconverted stream is not provided with vector information, is used and in a situation where an interframe predictive coding mode, in which the unconverted stream is provided with vector information, is used. Further, if an additional frame is referenced after searching for the corresponding frame, the circuit scale and power consumption increase. To solve the above problems, the disclosed transcoder comprises a decoder for decoding an input motion picture stream and detecting sub-information indicating whether an intraframe coding scheme or interframe predictive coding scheme is used; and an encoder for changing the frame to be referenced at the time of coding depending on whether the sub-information indicates the use of the intraframe coding scheme or interframe predictive coding scheme.

摘要： The time required to transcode an encoded image signal to an image signal encoded by a different encoding method is reduced. Disclosed herein is a transcoder comprising: a picture selector 4 which extracts specific types of pictures (I- and P- pictures) from a first image signal (MPEG2 stream) and generates a subset of the first image signal; a first decoder 5 which decodes the subset image signal; and a first encoder 7 which encodes the decoded image signal to a second image signal (MPEG4 stream). The picture selector 4 uses the extracted pictures to generate the subset image signal with a reduced effective length.
