    摘要： The present invention relates an adaptive video transcoding method and system, the method and the system for considering an available network bandwidth, a characteristic of a video, and a calculated load of a server, and adaptively controlling an encoding option of a transcoder, when carrying out a video transcoding such as a decoding of a video and video editing, and an encoding process, so as to enable a transcoding of a maximum number of videos in a limited environment. The adaptive video transcoding system according to the present invention comprises: a video transcoding device for calculating a minimum required compression rate required by a measured streamable bandwidth, selecting, as a transcoding encoding option, each of encoding options making up an encoding option combination with the lowest CPU usage rate of when at least one encoding option, from an encoding option combination having a greater compression rate of when at least one encoding option is combined and encoded, than the minimum required compression rate, is combined and encoded, and using the selected transcoding encoding option to transcode and transmit the video contents to a user terminal; and a user terminal for receiving and displaying the video contents transcoded according to the transcoding encoding option from the video transcoding device.

    摘要： The present invention relates to an image encrypting/decrypting system and method devised in such a way that: a transmitter and a receiver for transmitting and receiving moving images share a seed for encrypting and decrypting the moving images; the transmitter transmits moving images after encrypting the moving images by dividing them into segment units and mixing the time sequencing of the images in each of the segments in accordance with a random number generated by means of the seed; and the receiver decrypts the moving images which it receives, by sorting them in segment units and then restoring the time sequencing of the images in each of the segments in accordance with the random number generated by means of the seed. The present invention makes it possible to effectively implement the function of encrypting after having carried out transcoding even in cases involving an alteration to the frame or an increase in resolution in an encrypted moving image, and also makes it possible to resolve the problem of having to encrypt/decrypt before/after carrying out transcoding in cases where a compressed moving image is being encrypted.

    摘要： The present invention relates to a moving image coding apparatus and method involving the simultaneous parallel running of respective modules, namely: a segment-unit-coding module in which an input image frame is divided into segment units and the integer pel (integer pixel) motion is estimated while at the same time the 1/n pixel images are generated with respect to the segments of the image coded in the coding module; and a macroblock-unit-coding module in which the segments of the image frame whose the integer pel motion has been estimated in the segment-unit-coding module are received as input in the form of macroblock units and are coded in macroblock units through the 1/n pixel motion estimation. By separating the coding units into different modules and employing the techniques of parallel processing and pipelining, the present invention makes it possible to effect high-speed encoding with reduced delay in the coding rate due to differences in the processing speeds of the respective modules.
