  • Patent number: 5561467
    Abstract: High resolution vertical and horizontal components of a high definition video signal are combined with a standard broadcast system video signal, such as the NTSC system, in which high frequency horizontal resolution components are sampled and used to modulate at least a first sub-carrier signal. The first sub-carrier is frequency interleaved onto the standard broadcast signal. Vertical high resolution components are time compressed and time division multiplexed onto top and bottom portions of the standard broadcast signal. The modified broadcast signal can be decoded by a standard receiver to display a standard resolution video image, while receivers designed to decode the modified signal can time division demultiplex the vertical high resolution components and demodulate the horizontal high resolution components, combine these components with the standard components, and generate a high definition video image.

  • Patent number: 5320782
    Abstract: Acicular or platy titanium suboxides, expressed by the general formula, TiOx where x is a positive real number less than 2, have a geometric anisotropy as an aspect ratio in the acicular or platy form of 3 or more, a higher specific surface area and a greater geometric anisotropy even in comparison on the basis of the same degree of reduction, and are capable of retaining their native configurations during the reduction. The resin mediums incorporated with the acicular or platy titanium suboxides have good electric properties, and a higher mechanical strength.

  • Patent number: 5151779
    Abstract: A signal transmission system for high definition television that can handle a second television signal which is superior in quality to a first television signal such as an NTSC (National Television System Committee) television signal. The transmitting end of the system transmits a first television signal including a video signal, audio signals, etc., through a main transmission line, as well as a third television signal including a high definition components obtained as the difference between the second and the first television signal through an auxiliary transmission line. The receiving end of the system receives and synthesizes the first television signal transmitted through the main transmission line and the third television signal transmitted through the auxiliary transmission line to produce the second television signal.

  • Patent number: 5072297
    Abstract: A method and system for multiplexing additional audio information in the form of pulse code modulation (PCM) audio signals onto a television signal. The PCM audio signal is time multiplexed into scanning retrace intervals of the video signal. At a receiver, the bit error rate of the decoded PCM audio signal is compared with a threshold so as to switch the audio output from the PCM audio signal to a conventional FM demodulated audio signal when the bit error rate exceeds the predetermined threshold. In this way, the benefits of both PCM audio and FM audio can be obtained by utilizing the higher immunity of FM signals in low signal-to-noise ratio environments, while the high fidelity PCM audio signal is utilized when the signal-to-noise ratio environment is relatively high.
