摘要:
Since there is a case where reproduction of metadata is limited according to the processing power of a reproduction apparatus or the designation from a user, the invention provides a data structure in which metadata whose preferential reproduction is desired can be selected and reproduced. The metadata relevant to a moving image includes a stream data structure including one or more access units each being a data unit which can be independently processed, and each of the access units includes first data to specify an effective period defined with respect to a time axis of the moving image, object area data describing a spatio-temporal region in the moving image, second data including one of or both of data to specify a display method relevant to the spatio-temporal region and data to specify a processing to be performed when the spatio-temporal region is specified, and third data to specify, in a case where one or more access units exist on a same screen in the moving image at a time of reproduction of the metadata, reproduction priority of each of the access units.

There is provided an invention in which a buffer size and a data buffering size before a reproduction start can be determined according to a transfer rate of data and a network protocol used. In metadata of a moving image, a dynamic range of a data amount in a buffer is described, and the buffer size and the data buffering size before the reproduction start of the metadata are determined by this dynamic range.

A video transcoding method comprises decoding a first bit stream encoded by a first video encoding format to obtain decoded video data and side information, converting the decoded video data and side information into a form suitable for a second video encoding format to obtain converted video data and converted side information, and encoding the converted video data using motion vectors contained in the side information to obtain a second bit stream of the second video encoding format.

A tunable LD with reduced number of the butt joint is disclosed. The tunable LD includes the reflector and a waveguide core. The reflector includes a plurality of segments each having a grating region and a space region adjacent to the grating region. The waveguide core includes a gain region extending in two segments adjacent to each other and a tuning region extending in two segments adjacent to each other and also adjacent to the segment for the gain region.

A wavelength monitor monolithically integrated with a tunable LD is disclosed. The wavelength monitor includes at least two filters, each having a periodic transmission spectrum but a period between nearest neighbor periods is different from the other. A transmittance of the first filter and another transmittance of the second filter at a grid wavelength attributed to the WDM system forms a combination which is specific to the grid wavelength bur different from other combinations at other grid wavelengths.

A specifying unit specifies a pixel value at a pixel position of a reference image to a pixel of a sample enlarged image at a position relative to a pixel position of the reference image as an initial pixel value. A selecting unit selects a target pixel from pixels other than pixels having the pixel values specified therefor including the pixels having the initial pixel values are set in the sample enlarged image. An allocating unit configured to allocate the pixel value of the pixel at a similar region position of the reference image to the pixel value of the target value in the sample enlarged image when a searching unit searches the similar region position similar to a pixel value pattern including a set of already specified pixels in a spatial neighborhood of the target pixel from the reference image is provided.

A method includes inputting to-be-processed data including a set of first-N-dimensional-coordinate values in an N-dimensional space and first-sampling values, inputting search-pattern data including a set of second-N-dimensional-coordinate values in the N-dimensional space and second-sampling values, setting a set of virtual-corresponding points designated by third-N-dimensional-coordinate values, acquiring input patterns each including third-sampling values within a first range with reference to a corresponding virtual-corresponding point, acquiring search patterns each including fourth-sampling-values within a second range with reference to a corresponding second-N-dimensional-coordinate value of the second-N-dimensional-coordinate values in correspondence with each of the second-N-dimensional-coordinate values, detecting, from the search pattern data, an estimated pattern including one search pattern and having smaller differences with respect to the input patterns than other search patterns, setting sampling values at first positions corresponding to the virtual-corresponding points in the estimated pattern as sampling values at the virtual-corresponding points, and converting a sampling rate of the to-be-processed data.

An image processing device includes an acquisition unit, a memory, a search unit, and a synthesis unit. The acquisition unit acquires a moving image including a plurality of images, and sets a pixel in a process image as a target pixel. The process image is to be processed in the moving image. The memory stores a fine texture image obtained by extracting a texture component in a reference image different from the process image. The search unit sets a pixel position of the target pixel as a first position, and to search a predetermined range in the fine texture image in order to find a second position corresponding to the first position. The synthesis unit synthesizes a pixel value of the second position in the fine texture image with a pixel value of the target pixel.
