Abstract: Even when specific information (first information, second information) about individual sensors is inadequate to identify each of the individual sensors, whether all the sensors coupled to a semiconductor device are authentic can be determined. The semiconductor device can be electrically coupled with plural sensors and is configured as follows. Registration information is generated based on first combined information composed of plural combined pieces of first specific information respectively about plural sensors coupled to the semiconductor device when making registration. The semiconductor device generates determination target information based on second combined information composed of plural pieces of second specific information respectively about plural sensors coupled to the semiconductor device when making determination and compares the determination target information with the registration information.

Abstract: There is included a detection unit for detecting a magnitude of a surplus of a direct current to a source voltage generated by a voltage generation unit generating the source voltage from the direct current obtained by rectifying a signal inputted from an antenna terminal. A data processing unit operating at the source voltage and performing data processing on a transmission/reception signal includes a clock control unit for determining a frequency of a clock signal for the data processing based on the magnitude of the surplus current detected by the detection unit in a state where a frequency of the clock signal is set to a predetermined reference frequency. Since the power consumed by the data processing unit at the time of detecting the surplus of the direct current is determined by the specific reference frequency, the surplus of the direct current can be detected as an absolute surplus.

Abstract: Input terminals to which two types of serial data with similar formats are sent are disposed. Video data sent to the normal dubbing input terminal is data that has not been compressed/encoded. Data sent to the straight dubbing input terminal is data that has been compressed and encoded. Data received from the input terminal includes a sync error flag (error flag for each sync block) that is OR output data of data added by a reproducing VTR and transmission error information. The sync error flag is sent to an ECC encoder through a format converter not through an BRR encoder. An output signal of an ECC encoder is recorded to a magnetic tape by recording heads through a recording driver.

Abstract: A line number LN is extracted from serial data corresponding to BTA S-004 standard. The line number LN is placed as LN0 and LN1 to each of a luminance signal Y and color difference signals Pr/Pb of a 4:2:2 signal. The 4:2:2 signal is converted into a 3:1:1 signal by a bandwidth-compressing means. In addition, the 3:1:1 signal is re-arranged to two-channel signals Ch0 and Ch1 with the same format at a transmission rate of 46.40625 MHz. Thereafter, the, signals are processed at the transmission rate of 46.40625. The line number LN is placed as LN0 and LN1 at the beginning of one horizontal interval.

Abstract: Reproducing heads reproduce signals from a tape in advance of recording heads for a time period equivalent to a system delay. An ECC decoder corrects an error of a signal received from each reproducing head. A BRR decoder decompresses and decodes the signal received from the ECC decoder. A concealing circuit interpolates the signal received from the BRR decoder. An output signal of the concealing circuit is sent back to a selector of the recording system. The selector switches between a signal received from an input terminal and the reproduced signal at the end of each field. An intra-field encoding process or an intra-frame encoding process can be selected as an compressing and encoding process. Information that represents the selected encoding process is recorded on the tape.
