摘要： The present invention provides a video encoding device in which a capacity of a binary data storing unit is small, a size of the video encoding device is small, a video signal can be processed in real time, and reduction in quality of images generated from the eventually obtained data can be prevented. The video encoding device according to the present invention includes: a video encoding unit which encodes a video signal; a binarization unit which binarizes an encoded value obtained from the video encoding unit; and an entropy encoding unit which subjects entropy encoding to binary data obtained from the binarization unit. Here, the video encoding unit encodes the video signal based on a characteristic of the binarization performed by the binarization unit, so that an amount of binary data obtained from the binarization unit by binarizing the encoded value that is encoded based on the characteristic is less than an amount of binary data obtained by binarizing an encoded value that is encoded without being based on the characteristic.

摘要： To provide a recording and reproducing apparatus that recovers contents having approximately the same quality as the original contents in a short time and requiring only light processing load, at the time of (a) moving the contents from the first recording medium to the second recording medium, (b) rewriting the contents in order to disable reproduction of the contents, (c) reconstructing the original contents by recovering the contents from the second recording medium to the first recording medium. The recording and reproducing apparatus includes a move processing unit 72a and a recovery processing unit 73a. The former records reconstruction information on the second recording medium in association with the second contents, the reconstruction information being used in reconstructing one or more parts of the contents that have been rewritten in order to disable reproduction of the contents at the time of moving the contents. Also, the latter reconstructs the original contents based on the remaining contents recorded on the first recording medium by recovering the reconstruction information from the second recording medium and using the reconstruction information.

摘要： A transcoder reduces the processing amount when a coded stream to which at least intra prediction is applied is transcoded into a coded stream to which intra prediction and inter prediction are applied. The transcoder converts a first coded stream to at least part of which intra prediction is applied, into a second coded stream to which intra prediction and inter prediction are applied. The transcoder includes a decoding unit that decodes the first coded stream to generate decoded image data; a prediction mode obtaining unit that obtains a prediction mode of intra prediction applied in decoding; and a coding unit that codes the decoded image data by applying the intra prediction or inter prediction to generate the second coded stream. A control unit controls causes the coding unit to use the prediction mode obtained by the prediction mode obtaining unit when the coding unit applies intra prediction.
