    Abstract: PURPOSE:To improve the use convenience of a user at the time of program search processing by comparing an audio signal with plural threshold levels, and recording melody non-existence information and melody existence information obtained in accordance with a result of comparison together with the signal. CONSTITUTION:An inputted audio signal S1 is compared with plural threshold levels VR1-VR4 being different from each other, and when it is below the minimum level VR4, melody non-existence information is generated. On the other hand, when the audio signal S1 is above any level VR1-VR4, melody existence information containing its level is generated, and the melody non-existence information or the melody existence information is recorded onto a recording medium 1 together with the audio signal S1, therefore, the melody non-existence and the melody existence information can be recorded surely irrespective of the audio signal level. Also, at the time of reproduction, by comparing the set input threshold level and the reproducing threshold level of melody existence information, a melody existence part is retrieved, therefore, in accordance with the audio signal, the melody existence part can be retrieved.

    Abstract: PURPOSE:To prevent the deterioration the burst error correction length by expanding the final interleave interval of the P series and reversing the direction of retarding the interleave so as to locate the final word of the Q series after the preceding word. CONSTITUTION:The final interleave interval of the P series is expanded as to the P and Q series with respect to an optional word and the interleaving is applied to restore a word W7 and the Q series in reverse direction so as to locate the final word of the Q series after the recording word. Thus, even if an error exceeding the correctable burst error length takes place, the remaining error is reduced. Moreover, in order to improve the error correction capability at the simultaneous occurrence of a burst error and a random error, it is preferred to take the largest interleave delay quantity (quantity of restoration) in the reverse direction. Thus, the deterioration in the burst error correction capability is prevented and the deterioration in general error correction capability is prevented.

    Abstract: PURPOSE:To prevent the reduction in the error correction capability by setting the interleave interval of an error correction code series longer partially to evade any word of P and Q series with respect to a prescribed object work from being duplicated in the recording direction. CONSTITUTION:The interleave interval of the error correction code series is set longer partially so as to evade the duplication in the recording direction as to words W0-W7 of the P and Q series with respect to the optional object word. Thus, even when the interleave interval is taken sufficiently large due to a small block size, the same frame except the object word is avoided as to each word of each error correction code system with respect to an optional object word. Thus, the reduction in the error correction capability is prevented.

    Abstract: PURPOSE:To improve the conversion accuracy by holding the voltage of a capacitor at a time synchronously with a prescribed clock after an integration voltage reaches a prescribed voltage by means of a sample and holding circuit and adding an output of the sample and holding circuit to an input signal of the next sampling period. CONSTITUTION:The AD conversion section 10 is provided with a capacitor 2 receiving an analog input signal from an input terminal 1 at a prescribed period of sampling and a current source 3 to integrate the voltage, and the counting operation of a counter 5 is stopped just after the integration output exceeds the threshold value of a comparator 4. The voltage change by integration is quantized by turning off a switch SW3 of the current source 3 synchronously with the first cock after the integration output exceeds a prescribed threshold value of the comparator 4 and a difference from the analog input voltage is held in the capacitor 2. The error voltage is stored in a capacitor 21 of the sample and holding circuit 20, added to the input signal of the next sampling period and the added signal is used as the next AD conversion input. Thus, the quantization error is fed back.

    Abstract: PURPOSE:To detect assuredly an error of a data word by considering all words of a block containing words with which the errors are detected at a time as erroneous by the error check codes obtained from plural series of different data blocks of a prescribed number of data words. CONSTITUTION:A data block formed with a prescribed number of data words D1, D2-, the P- and Q-series parity check codes P and Q different from the data block series, a cyclic redundancy check code C of said block series, etc. When the errors of words D1, D2- which cannot be detected by the code C are detected by the codes P and Q, flags F1-F4 for P and Q series of wrong words D1, D2- are all set at ''1''. At the same time, the all flags of other words D1, D2- of the corresponding block are also set at ''1'' and considered as erroneous. Thus it is possible to detect a word error with no overlooking.

SOLUTION: An arrow c1 for connecting an FCS 22, a CPU 21, a memory controller 23, a DDR-PHY controller 25, and a clock controller 26 is a signal for requesting frequency changeover. An arrow c2 is a signal for inputting a Self Refresh Enter command. Consequently, an LPDDRSDRAM 29 is operated in a self refresh mode. An arrow c4 is a signal for requesting the reset of DDR-PHY 24. An arrow c6 is a signal for requesting clock frequency changeover. An arrow c8 is a signal for requesting parameter setting of DDR-PHY, thereby selecting a DLL or a DL mounted on the DDR-PHY 24 as the one to be used, and determining a parameter to be set, etc. An arrow c10 is a signal for inputting a Self Refresh Exit command. An arrow c12 is a signal for announcing termination which expresses the termination of the frequency changeover. COPYRIGHT: (C)2010,JPO&INPIT
