摘要： In general, according to one embodiment, an image distribution device of the embodiment includes a receiver, a compressor, a request acceptor, a determiner, and a distributor. The receiver receives data captured by an imaging device of an in-vehicle device mounted in a vehicle. The compressor compresses the captured data of after elapse of a certain time to generate compressed captured data. The request acceptor accepts a distribution request to specify a desired time from an information processing device. The determiner determines whether the desired time is a past time within a certain time from a present time. The distributor distributes, when the desired time is the past time within the certain time from a present time, the captured data to the information processing device, and distributes, when the desired time is a past time prior to the certain time, the compressed captured data to the information processing device.

摘要： A video decoder obtains a first set of picture buffering parameters associated with a current picture of an encoded video bitstream. The first set of picture buffering parameters identifies a set of one or more reference pictures for use in decoding the current picture by a graphics processor. The video decoder revises the first set of picture buffering parameters into a second (different) set of picture buffering parameters for use in decoding the current picture by the graphics processor. The second set of picture buffering parameters is transferred to the graphics processor for decoding the current picture.

摘要： For compressing a video signal, a local multiscale transform is applied to a frame of the video signal to obtain coefficient blocks. The coefficients of each block are distributed into coefficient groups associated with that block. A plurality of the coefficient groups associated with a block are processed. The processing of one of the groups comprises determining an exponent for encoding the coefficients of that group. Mantissas are determined for quantizing the coefficients of the plurality of groups in combination with the exponents respectively determined for these groups. Coding data including each exponent determined for a coefficient group and the mantissas quantizing the coefficients of the group in combination with this exponent are stored in an external frame buffer. The mantissas determined for quantizing the coefficients of one of the groups are represented in the coding data by a respective number of bits depending on the exponents determined for the plurality of coefficient groups.

摘要： An apparatus and a method for temporary storage of image-encoding data are provided. The apparatus for temporary storage of image-encoding data is utilized for high-resolution image encoding, wherein the apparatus includes an image sensing unit, a storage unit, and an encoding unit. The image sensing unit creates a plurality of frame data in successive order. Each frame data is composed of a plurality of macroblock row data. The storage unit includes a first storage portion and a second storage portion. The capacities of the first storage portion and the second storage portion are both a positive integral multiple of the size of the macroblock row data. The storage unit receives the macroblock row data from the image sensing unit and writes the macroblock row data into one of the first storage portion and the second storage portion. When the encoding unit reads the written macroblock row data from one of the first storage portion and the second storage portion, the storage unit simultaneously receives new macroblock row data from the image sensing unit and writes the new macroblock row data to the other one of the first storage portion and the second storage portion. The design of the first storage portion and the second storage portion is utilized to conserve storage space.
