  • Patent number: 7151559
    Abstract: When a TS (Transport Stream) generator generates a TS, the TS is modulated by a signal modulator and outputted to a tuner set. In the tuner set, various noises generated by a noise source are added to an input signal, reception processing is performed, and then the resultant signal is outputted to a LVDS (Law Voltage Differential Signal) converter. The LVDS converter converts the input signal into a LVDS of the same format as TS, and outputs the LVDS to an error rate measuring device. The error rate measuring device find a difference between the generated TS and the inputted LVDS while adjusting a synchronization and outputs the difference to a personal computer. The personal computer compares the inputted difference with a predetermined BER (Bit Error Rate), and determines performance regarding the reception process of the tuner set based on the comparison result.

  • Patent number: 7148933
    Abstract: A projector employing a linear array of light-emitting sources forms a super pixel in the form of a plurality of beams that are focused onto scanning optics that cause the beams to move across a viewing surface on a first axis for defining image lines along the first axis and on a second axis such that super pixel overwrites every addressable spot on the viewing surface thereby producing interleaved and staggered scan patterns that hide the effect of burned out, misdirected, or marginally operating light-emitting sources that would otherwise result in a degraded projected image. An alignment system that includes alignment electronics that is responsive to a charge-coupled device facilitate adjusting the scanning optics to allow precise alignment of individual ones of the light-emitting sources and to detect burnt out individual ones of the light-emitting sources.

  • Patent number: 7142246
    Abstract: An output stream of the de-interlaced image frames is produced from an incoming stream of interlaced image fields, where the interlaced image fields include complementary pairs of fields, which together comprise a frame. An input buffer includes field buffers storing the incoming stream of interlaced image fields. Field match detection logic is coupled to the input buffer, and detects matching fields in field buffers storing fields from the incoming stream separated by one other field. De-interlace logic is coupled to the input buffer and reads complementary pairs of fields from the input buffer and outputs de-interlaced frames. Control logic causes the current field from one of the field buffers to be paired with a complementary field selected from one of two fields stored in adjacent field buffers. The control logic sets a mode for the de-interlace sequence, including a standard mode and a 3:2 pulldown mode.

  • Patent number: 7133082
    Abstract: An outdoor-antenna digital television receiver system has an electrically controlled remote tuner located close to the antenna. In response to a remote control signal, the remote tuner selects a particular radio-frequency digital television signal to be received, converts that RF DTV signal to an intermediate-frequency digital television signal of prescribed carrier frequency, and drives a downlead transmission line, preferably a coaxial cable. Indoors, the downlead transmission line is provided with an echo-free termination This echo-free termination may be in a “set-top” box that includes a frequency up-conveter that converts the IF DTV signal back to an RF DTV signal for reception by a conventional digital television receiver. Alternatively, the echo-free termination may be in a special DTV receiver without a local tuner.
