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.

摘要： PROBLEM TO BE SOLVED: To solve problems of the conventional digital data storage system for storing digital data that a larger amount of data are required in the case of storing non-compression data in comparison with that of compressed data (1), storage of a plurality of compressed data by each compression system is required since the required compression system differs depending on users although the contents of the data are the same in the case of storing compressed data (2), and the copyright of multimedia data such as audio and video data should be protected (3). SOLUTION: A control process 101 stores received compression data 106 to a storage 102. On the other hand, when outputting the stored compression data according to control information 107, a control process 101 uses an expansion process 103 to expand the compressed data into non-compression data, uses a watermark embedding process 104 to embed watermark information to the non-compression data after expansion, uses a compression process 105 to compress the non-compression data after the embedding into compressed data, and outputs the resulting compressed data. Thus, many more contents can be stored in comparison with the non-compression data. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To decode the digital speech signal of plural different formats by suppressing the increase of the capacity of internal RAM and of an operation clock frequency. SOLUTION: Two digital signal processors(DSP) 8 and 3 are used and each of them shares the load of audio decoding processing. DSP 8 decode-processes an audio BS(bit stream) from an input terminal 1 by a frame unit and generates frequency coefficient data to write into an external memory 11. DSP 3 reads frequency efficient data of this frame unit and decode-processes it to be PCM (pulse encoding) sample data. This PCM sample data is supplied for a D/A converter 6 through a PCM output I/F circuit 5 and converted to an analog speech signal. In a case when DSP 8 cannot decode-process one frame of audio BS in one frame period because of overloading, a deadline control circuit 12 makes DSP 8 to process the remainder in the next period and makes DSP 3 interpolate-operate in this frame period.

摘要： PURPOSE: To attain intuitional and smooth selection and viewing of a program by extracting partially the program, multiplexing the program and sending the result to a decoder and displaying a broadcast image on a same screen in a menu form. CONSTITUTION: A bit stream received from a delivery equipment to an STB 1 is given to a tuner/demodulator 2, in which a stream designated by the user is selected and demodulated. The demodulated stream includes a multiplex program and it is fed to a system decoder 3 and a distributer 4. The decoder 3 extracts the information representing the attribute of a program number or the like and gives the information to the distributer 4 and a controller 8. The distributer 4 sends the data to a multiplexer 5 according to the result of analysis. The stream of the multiplexer 5 is given to one input of a changeover circuit 6. The stream bypassing the multiplexer 5 is fed to the other input of the circuit 6. The changeover circuit 6 selects the stream according to a mode signal from a controller 8 and gives it to a decoder 7.
