Patent number: 5537159Abstract: The nonlinear, deflection waveform used improve registration in a three picture tube projection television system is produced using interpolation of stored data setting points by first performing a reduced number of high-order interpolation calculations using the setting points and then performing low-order interpolation calculations either between two calculated high-order interpolated data points or between one of the calculated high-order interpolated data points and one of the setting points. This results in reducing the work load on the central processing unit in the registration system. In addition, a reduced bit-size requirement for the interpolation portion of the registration is obtained by storing registration data of a first bit size and then adding bits below the original LSB for the interpolation calculation prior to performing the digital to analog conversion.Type: GrantFiled: May 19, 1994Date of Patent: July 16, 1996Assignee: Sony CorporationInventors: Masayuki Suematsu, Toshihiko Hamamatsu, Makoto Kondo

Patent number: 4633313Abstract: Digital data transfer in a digital television receiver between an internal central processing unit, or an external computer, and the video/audio processing circuitry by way of an internal bus is accomplished efficiently and without producing noise interference by using a high-frequency clock signal and a relatively low-frequency clock signal at different times. The high-frequency signal would normally produce visually perceptable noise, however, it is employed only during vertical blanking intervals, and the low-frequency clock signal, which would not produce visually perceptable noise, is used at all times other than the vertical blanking intervals, whereby noise interference that would be otherwise seen on the visual display of the television receiver is suppressed.Type: GrantFiled: January 7, 1986Date of Patent: December 30, 1986Assignee: Sony CorporationInventors: Takao Mogi, Masayuki Suematsu

Patent number: 4275354Abstract: First and second counters in a pulse width modulating circuit, whose respective outputs determine the trailing and leading edges of a pulse width modulated signal, count input clock pulses at a constant speed. The number of the pulses applied to the second counter during a cycle relative to the number of the pulses applied to the first counter is increased or decreased by one in response to a modulating pulse to change the counting phase of the second counter thereby changing the width of the pulse width modulated signal. Gates freeze the phases of the two counters at minimum and maximum pulse widths of the pulse width modulated signal to avoid abrupt jumps from minimum to maximum or vice versa.Type: GrantFiled: January 19, 1979Date of Patent: June 23, 1981Assignee: Sony CorporationInventors: Masayuki Suematsu, Takao Mogi, Akira Taki
