  • Patent number: 8049818
    Abstract: The present invention relates to a video processing method and apparatus capable of performing a proper video process corresponding to various color systems. A decoder extracts color information from a received video signal including vertical synchronous information for a vertical scanning frequency of a picture, color information of the picture, and frequency information corresponding to the color information. A frequency evaluator evaluates the received vertical scanning frequency and the received frequency of the video signal color information on the basis of the vertical synchronous information and the frequency information of the color information.

  • Publication number: 20040259516
    Abstract: An apparatus and a method of controlling a low noise amplifier of a receiver, in which the activation of the low noise amplifier is automatically controlled using an automatic gain control current for a received signal. The apparatus may include a low noise amplifier, an automatic gain control current detector, a switch, and a controller. The low noise amplifier amplifies a noise-free received signal. The automatic gain control current detector detects an automatic gain control current based on the level of a signal output from the low noise amplifier. The switch controls the activation of the low noise amplifier. The controller controls the operation of the switch according to the automatic gain control current detected by the automatic gain control current detector.
