20090190655MOVING PICTURE ENCODING APPARATUS - An encoding circuit (07-30-2009
20090296809ENCODING/DECODING DEVICE, ENCODING/DECODING METHOD AND STORAGE MEDIUM - This is an encoding device for compressing/encoding an input video signal. The encoding device comprises a reduction/conversion unit for converting the format of either a luminance component or a chrominance component according to the characteristic of the input video signal and an encoding unit for compressing/encoding the video signal whose format is converted by the reduction/conversion unit to generate encoded data.12-03-2009
20100054335Encoding apparatus and decoding apparatus - An encoding apparatus having a direct mode as a prediction mode, when a pixel with opposite parity from a top field to a bottom field, for example, is referred to for obtaining a reference vector in the direct mode, performs correction by adding or subtracting a value corresponding to a half pixel to or from a value of the obtained reference vector. The encoding apparatus, when a pixel with opposite parity is referred to for obtaining a first and a second direct vector by temporally scaling the corrected reference vector, performs correction by adding or subtracting a value corresponding to a half pixel to or from values of the obtained direct vectors.03-04-2010
20100061445Moving picture editing apparatus - A moving picture editing apparatus includes a picture extracting unit that extracts pictures of a predetermined range including a picture subsequent to a coupling point from encoded data to be coupled; an adjustment-information generating unit that generates adjustment information for adjusting values of information to be continuous from/to inside to/from outside the predetermined range upon decoding, from among information included in headers of the pictures of the predetermined range extracted by the picture extracting unit; and a re-encoding unit that adds the adjustment information generated by the adjustment-information generating unit to the headers of the pictures of the predetermined range extracted by the picture extracting unit, and re-encodes the pictures of the predetermined range.03-11-2010
20100074338VIDEO ENCODING METHOD AND APPARATUS, AND VIDEO DECODING APPARATUS - To allow a finer quantization control according to the property of an image within a macroblock, quantization parameter values are allowed to be changed in units of sub-blocks equal to or smaller than the macroblock in a similar manner as in motion compensation and orthogonal transform processes. A finer-tuned quantization control is performed, for example, by selecting fine and coarse quantization parameters respectively for corresponding sub-blocks if a plurality of images having different properties coexist within the macroblock.03-25-2010
20100172412VIDEO ENCODER AND VIDEO DECODER - A video encoder that encodes each of a plurality of blocks obtained by dividing an input image, includes: a definition unit configured to define a valid area which is allowed to be used as reference in a reference image in interframe coding; a detection unit configured to detect a reference area in the reference image for a target block; a predicted image generation unit configured to generate a predicted image by outputting an image of the reference area for the reference area belonging to the valid area and outputting a complementary image for the reference area not belonging to the valid area; and a coding unit configured to encode the input image using the predicted image, wherein valid area information indicating the valid area is transmitted to a video decoder, for each group of a plurality of blocks.07-08-2010
20100226624INFORMATION PROCESSING APPARATUS, PLAYBACK DEVICE, RECORDING MEDIUM, AND INFORMATION GENERATION METHOD - A detecting section in an information processing apparatus is configured to detect an event sound from audio, the audio having been recorded when video was shot. The information processing apparatus also includes a calculating section configured to determine an event playback time at which an image associated with the event sound is played back in a video playback time sequence, the video playback time sequence corresponding to a playback speed lower than a shooting speed of the video and a determining section configured to determine a playback start time of the event sound during the video playback time sequence in accordance with the event playback time.09-09-2010
20100303370VIDEO DECODING DEVICE AND VIDEO DECODING METHOD - A video decoding device includes a decoder configured to decode a plurality of separate partial areas of each of pictures included in encoded video data and a motion vector indicating a positional relationship between each of the partial areas and a partial area of a different picture referenced in order to encode the partial area; an error detector configured to detect, as an error area, a partial area that is unable to be decoded by the decoder from among the plurality of partial areas; a referenced area determiner configured to determine a referenced area of a third picture that has already been decoded, the referenced area corresponding to the error area; a concealment unit configured to conceal the error area using data included in the referenced area; and an image integrator configured to reproduce the first picture.12-02-2010
