    摘要: A transcoding method and apparatus designed to reduce, with a high picture quality, the computation processing volume required for transcoding are provided. A recording and reproduction apparatus 100 includes an encoder 101, a transcoder 102, an intermediate information storage memory 105, a stream storage memory 106, a compression expansion means 107, an input image storage memory 108, and a user interface 110. When performing encoding in an encoder 104 with a second compressive encoding method, the intermediate information is read from the intermediate information storage memory 105, processed into a utilizable format, and utilized during encoding with the second compressive encoding method.

    摘要: In increasing multi-channel broadcast situations, user friendliness is insufficient in that digest information can not be generated to satisfy users' demands to record two contents which are broadcast at the same time. In a reproduction apparatus which simultaneously records a plurality of digital video signals and creates a digest of each of the signals to shorten the reproduction time, particular frames of input digital video signals are recorded on a recording medium as reproduction position information. A first decoder decodes the digital video signals as a whole, and a second decoder decodes only digital video signals associated with the reproduction position information. The output of the second decoder is used as a digest generation signal of a digest generation module.

    摘要: An image transmission device compresses and transmits image data to be sent and cannot correct errors occurring on the transmission path when image data to be transmitted is larger than a currently prescribed image size. In an image receiving device which receives compressed image data, data to be inputted is inputted by switching between first periods, during which the amount of data transmitted per prescribed time interval is a first data transmission amount, and second periods, during which the amount of data transmitted per prescribed time interval is less than the first data transmission amount. Compressed image data is inputted during the first periods, and error correction codes are inputted during the second periods, and a control unit expands the output of an error detection unit by means of an expansion unit and outputs the same.

    摘要: The present invention provides an image decoder which decodes a stream encoded with standard resolution and transforms it into a high-definition image with a better image quality. An intra-field pixel interpolation module generates an interpolated pixel using pixels in a field. An inter-field pixel interpolation module generates an interpolated pixel using pixels from another field. A weighted averaging module refers to the prediction mode used in predictive encoding for the coded stream. If the prediction mode is a field prediction mode, it increases the mixture ratio of interpolated pixels generated by the intra-field pixel interpolation module, and if the prediction mode is a frame prediction mode, increases the mixture ratio of interpolated pixels generated by the inter-field pixel interpolation module.
