摘要： The invention aims at reducing the circuit size while maintaining the creation of a predictive image suitable for the intra prediction based on a pipeline processing. The encoding device is operated to perform intra prediction in blocks of pixels resulting from division of a frame of a moving image has a pseudo-local-decode-image-creation module for simply encoding an original image, and an intra prediction module for using the created pseudo local decode image to select an intra prediction mode. In the intra prediction based on pipeline processing, the pipeline stage for selecting an intra prediction mode and the pipeline stage for creating predictive image data according to the selected intra prediction mode are separated.

摘要： A technique for improving a compression rate without needing new determination information (encoding flag information) is provided. For compression of each area to be encoded, based on a skip mode (a process which does not compress information of the area to be encoded, but copies previous information of the area to be encoded), it is determined whether an existing predicted image generated by an existing encoding standard is used, or an interpolation predicted image newly generated by executing move searching between decoded images is used.

摘要： In expansion and reduction of the size of a macroblock in a moving image encoding, a compression ratio falls because an information amount for describing size information of the macroblock increases. An image decoding device includes a CU dividing unit and a CU-size storing unit. The CU-size storing unit has stored therein size information of an encoded CU in an encoding target picture to be stored and size information of all CUs in preceding and following pictures used for prediction. The CU dividing unit predicts a CU size in an encoding target position using the CU size information stored in the CU-size storing unit and determines a CU size of a final encoding target CU.

摘要： The present invention is directed to improve compression efficiency by variable-length coding in accordance with characteristics of image data to be processed. An apparatus for compressing quantized data by variable-length coding includes: a statistical information storing memory (212) for storing statistical information (MBTyp and CBPL) of coded image data; a variable-length code table generating unit (213) for generating a variable-length code table on the basis of the statistical information stored in the memory; and a variable-length coding unit (205) for performing variable-length coding on the basis of the variable-length code table. The variable-length code table generating unit generates a variable-length code table by adding occurrence probability of statistical information calculated within a predetermined range of the coded image data and initial occurrence probability selected on the basis of a coding parameter (S3005), and assigning a short code in descending order of statistical information obtained by the addition (S3006).

摘要： A vibration sensor has a first substrate, a second substrate relatively movable by an external vibration while opposed to the first substrate, an electret group having a plurality of electrets that are arrayed in a relative movement direction on a side of one of surfaces of the first substrate, and an electrode group having a plurality of electrodes that are arrayed in the relative movement direction on a side of a surface of the second substrate. The surface of the second substrate is opposed to the electret group. A positional relationship between the electret group and the electrode group changes with a relative change in position of the first and second substrates by the external vibration to output an external vibration detection signal.

摘要： For the purpose of providing an image encoding technique for reducing the amount of codes, in inter prediction in which motion search is performed by using a block obtained by dividing an input image and a reference image, the motion vector of the block is predicted by selecting from the motion vectors of the surrounding blocks. Further, in the method of calculating a differential vector and then performing encoding, the number or positions of candidate blocks from which a prediction vector is selected are changed block by block or frame by frame and thereby adaptive and efficient video image compression is performed.

摘要： During the reception of a content delivery service, if the service is continued by switching a communication path, a temporary interruption occurs upon the switching of a session. There are cases where the same service cannot be continued if the communication speed of the communication path prior to switching is greatly different from that of a communication path after switching. Sessions for delivering two contents each encoded from the same source data, having different bit rates, and temporally synchronized with each other are established simultaneously with respect to a client terminal. The sessions are switched at the client terminal based on information on the respective times of content data from the two sessions such that a temporal continuation is provided therebetween.

摘要翻译： 在接收内容传送服务期间，如果通过切换通信路径继续服务，则在切换会话时发生临时中断。 如果在切换之前的通信路径的通信速度与切换后的通信路径的通信速度大不相同，则存在不能继续相同服务的情况。 相对于客户端终端同时建立用于从相同的源数据编码的具有不同比特率并且彼此在时间上同步的两个内容的会话。 基于来自两个会话的内容数据的相应时间的信息，在客户终端处切换会话，使得在它们之间提供时间延续。

摘要： When the meta data in an MP4 file is converted, a media data recopying process involves a long process duration and large memory space allocation. The invention provides that when an MP4 file is converted, an increment of a converted file size is estimated based on previously-registered meta data conversion candidate information, an overwritable free space equivalent to the estimated incremental size is inserted before a media data portion. In the MP4 file conversion, the converted meta data overwrites the to-be-converted meta data portion and the overwritable free space such that the MP4 file is converted without moving the media data.
