摘要： PROBLEM TO BE SOLVED: To allow one device to reproduce plural broadcast programs and an information recording medium by providing a 1st demodulation circuit that demodulates a 1st transport stream, a 2nd demodulation circuit that demodulates a 2nd transport stream and multiplexing all or parts of packets of both the demodulated transport streams. SOLUTION: A radio wave from a 1st digital broadcast satellite is converted into a base band signal via a parabolic antenna 11a and a tuner 12a and a demodulation error correction section 13a decodes the signal into an original transport packet. A pre-processing circuit 14a writes identification of a packet to the header of the packet and the result is fed to a multiplexer section 15. A radio wave from a 2nd digital satellite broadcast is processed similarly. A multiplexed transport packet is once stored in a buffer memory 20 via an encryption decoding section 16. A demultiplexer section 17 extracts packets of a designated program from a series of packet flows.

摘要： PROBLEM TO BE SOLVED: To provide a method for interpolating image data photographed in an electronic photographing apparatus that has a Bayer matrix.
SOLUTION: To interpolate an interpolated pixel X33 (green pixel), an average value for surrounding pixels that position surrounding the interpolated pixel X33 is calculated, and then center values for the green pixel in the horizontal, the diagonal and the reverse diagonal directions included with the interpolated pixel X33 are calculated using following expressions (2) to (4) respectively. Finally, a value, the difference between the center value and the average value of which is the smallest, is to be pixel data for the green pixel that positions at X33. The expressions are expressed as follows:expression(1):ave=(G22+G24+G42+G44), expression(2):horiz=median(G31, (G22+G42)/2, (G24+G44)/2, G35), expression(3):Slash=median(G15, G24, G42, G51), expression(4):Bslash=median(G11, G22, G44, G55).

摘要： PROBLEM TO BE SOLVED: To reduce the bit width of a demodulator without deteriorating a bit error ratio by calculating a phase from the ratio of components I and Q based on n-bit data obtained by an automatic gain circuit and differentially decoding a calculated phase to decode data. SOLUTION: Quadrature detectors 21 to 23 convert intermediate frequency signals obtained based on a received signal into quadrature base band signals. Two correlating devices 33a and 33b respectively calculate correlation between a base signal and a spread code. An automatic gain control circuit 34 fetches n(m>n)-bit data from m-bit data respectively showing the components I and Q of the correlating value outputted by the correlating devices 33 based on the number of effective bits at each symbol frequency of the base band signal. The demodulator 31 calculates from the ratio of the components I and Q based on n-bit data obtained by the circuit 34 and differentially decodes the calculated phase to decode data.
