  • Patent number: 7027107
    Abstract: In a receiving device of the invention used in high-definition television, a frequency information storage section stores error information of a frequency error of a signal output from an oscillator. A control unit controls the oscillator based on the error information stored in the frequency information storage section. In a simple configuration, it is, therefore, possible to shift, the frequency in a direction of tuning by a tuner, to thereby output the signal with an appropriate frequency from the oscillator without being influenced by an accuracy of the oscillator, thus to demodulate the received signal accurately. Accordingly, it can be avoided such a problem that no pilot signal is present in an IF signal within a predetermined band width filtered by a SAW filter or that the pilot signal, even if present, cannot be received.

  • Patent number: 5351094
    Abstract: In a high quality TV receiver and an oblong standard TV receiver, when a TV signal having a smaller aspect ratio than those receivers is received, ugly pictures due to ringings and the like are adapted not to appear on the CRT screen surface even if a velocity modulation circuit is provided. An input TV signal having a small aspect ratio is structured from an image conversion circuit which includes a scanning time proportionate to an increasing aspect ratio of the TV receiver and a velocity modulation switch circuit which controls the operation of a velocity modulation circuit 16.
