  • Patent number: 7415717
    Abstract: A broadcasting system, receiving device, and method that allows the viewer to set conditions for the display of commercials (CMs) with broadcast programs. A broadcasting device transmits the programs and CMs via separate channels. A receiving device receives the separate channels and records the CM information. The receiving device combines the recorded CM information with the programs for display in accordance with customer requirements set by the viewer. The customer requirements are also sent back to the commercial broadcasting company to adjust the CMs transmitted to the viewer and the fees charged for viewing the programs.

  • Patent number: 5299022
    Abstract: A portable video camera and recording apparatus is comprised of a video camera section and a recording section. The video camera section is comprised of a CCD, analogue-to-digital converters for converting signals from the CCD into digital form. The digital signals are then processed, converted into analogue form, processed in analog form, and then output as the composite video signal. A digital luminance signal and either a digital composite color signal or a plurality of digital color difference signals are received as inputs into the recording section. If the digital composite color signal is received, then the signals are time-base-compressed, converted into analogue form, the composite color signal is frequency converted and filtered and the luminance signal is frequency modulated and filtered. Next, the signals are added together and recorded onto a recording medium.

  • Patent number: 4516172
    Abstract: A solid state television camera having a solid state image sensing device, such as CCD image sensing device and an iris for controlling the amount of light from an image irradiated on the image sensing device. The iris is controlled by the peak level of a smear signal of a horizontal scanning line during a vertical blanking interval so that the smear signal contained in a video signal from the image sensing device is reduced. Further, the iris can be controlled by the average level of the smear signal instead of the average level of the video signal of one field as the smear signal has the whole information of the image of one field, that causes the construction of detecting circuit to be very simple and the fidelity of the iris control to be high.

  • Patent number: 4355327
    Abstract: A digital color encoder for a television camera in which during digitally modulating a carrier of 3f.sub.sc (f.sub.sc is a color subcarrier frequency) with a digital color signal which is obtained by sampling input video information data at a sampling pulse rate having a frequency of 3(n/m)f.sub.sc (with m and n being relatively small integers) at N line the digital color signal is amplitude modulated by 3-phase modulation vectors each having a phase difference of 2/3.pi. from each other so as to produce a digitally modulated color signal. At N+1 line, the digital color signal is amplitude modulated by the 3-phase modulation vectors each having a phase opposite to that at the N line so as to produce an output of N+1 line which is then phase inverted to provide a digital modulated color signal. Thus, a digital color television signal with color phase having the standard television signal format is obtained.
