摘要： PROBLEM TO BE SOLVED: To achieve accelerated data download by multiplexing while keeping balance between communication usage amount and network usage situation.SOLUTION: The data delivery system comprises a data delivery server, multiple networks, a terminal that can request to deliver data and a communication data control server that controls usage situation of the networks. The terminal collects communication amount data in each network from the communication data control server, divides the data to be delivered into data blocks so that their communication usage amounts are equal to each other and requests the data delivery server to separately deliver them. The data delivery server determines whether the data blocks requested by the terminal can be delivered within a communication time limit defined by the system. If a time required for transmitting the data blocks exceeds the communication time limit, it is attempted to shorten the data transmission time by compression. If the data block transmission time still exceeds the communication time limit after the data compression, the data blocks are subdivided.
摘要翻译：要解决的问题：通过多路复用实现加速数据下载，同时保持通信使用量和网络使用情况之间的平衡。解决方案：数据传送系统包括数据传送服务器，多个网络，可请求传送数据的终端和控制网络使用情况的通信数据控制服务器。终端从通信数据控制服务器收集每个网络中的通信量数据，将要传送的数据划分成数据块，使得它们的通信使用量彼此相等，并请求数据传送服务器分别传送它们。数据传送服务器确定终端所请求的数据块是否可以在系统定义的通信时间限制内传送。如果发送数据块所需的时间超过通信时间限制，则尝试通过压缩缩短数据传输时间。如果在数据压缩之后数据块发送时间仍然超过通信时间限制，则数据块被细分。版权所有（C）2012，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a technology for providing a commercial message (CM) to a viewer without losing an advantage of digest viewing by preventing the CM from being cut off when the viewer carries out the digest viewing by using a television broadcast video recording reproducing apparatus. SOLUTION: A moving image digest function extracts features of image and audio in the unit of frames configuring a moving image, uses an evaluation function to evaluate the features, and records a result of the evaluation as a ranking value in the unit of frames. In the case of creating a digest, since the frames are used in a higher ranking order, display control of the CM can be attained by placing a high ranking to the CM parts and extracting a prescribed number of frames of the CM parts.

摘要： PROBLEM TO BE SOLVED: To enable a plurality of semiconductor devices to share an external memory without connecting a system bus and to enable the external memory to be directly connected to each of the semiconductor devices. SOLUTION: The expansion interface of a first semiconductor device receives from a memory controller B of a second semiconductor device a read request based on a protocol for an external memory A, and sends a read request for the external memory A to a memory controller A according to the read request. Data sent from the memory controller A according to the read request are sent to the memory controller B according to the protocol. If the data cannot be sent to the memory controller B at the normal timing of the protocol after the reception of the read request, the expansion interface outputs a stop signal to the memory controller B to stop the operation of the memory controller B until the data can be sent.

摘要： PROBLEM TO BE SOLVED: To provide a summary-reproducing apparatus capable of generating and displaying a summary which can look out over the content as a whole, regardless of the number of scenes contained in the original content.
SOLUTION: The summary-reproducing apparatus comprises a data-recording portion, a scene change detecting portion, a significance calculating portion, a scene-ranking portion, and a summary image reproducing portion. The data-recording portion records a plurality of still image data acquired, by respectively encoding a plurality of still images continued in time, series as motion image data. The scene change detecting portion detects scene change in a motion image acquired by reproduction of each still image data in time series, based on each piece of still image data. The significance calculating portion calculates index value, indicative of significance for each still image within the motion image, based on each piece of still image data. The scene-ranking portion ranks each scene, based on the index value is indicative of significance for a still image contained in each scene in the motion image. The summary image reproducing portion reproduces each still image contained in each scene, selected by only a predetermined number of them in the order of the ranking as summary immages.
