  • Patent number: 7502736
    Abstract: Disclosed is a voice registration method for voice recognition, comprising the steps of analyzing a spectrum of a sound signal inputted from the outside; extracting predetermined language units for a speaker recognition from a voice signal in the sound signal; measuring the loudness of each language unit; collecting voice data on registered (background) speakers including loudness data of the plurality of background speakers as a reference onto voice database; determining whether the loudness of each language unit is within a predetermined loudness range based on the voice data base; learning each language unit by using a multi-layer perceptron in the case that at least a predetermined number of language units are within the predetermined loudness range; and storing data on the learned language unit as data for recognizing the speaker. With this configuration, loudness of a speaker is considered at learning for registering his/her voice and at verifying a speaker.

  • Patent number: 6373527
    Abstract: A high definition television (HDTV) for displaying an image contained in a broadcasting signal of mutually different broadcasting systems is provided. The HDTV restores a first image signal which is an image signal contained in an HD digital broadcasting signal and a second image signal which is an image signal contained in an NTSC analog broadcasting signal which are input from an antenna and an external input port, and format-converts each restored image signal into an image signal having a predetermined frame format. An image signal synthesizer including two memories and a timing signal generator time-base-compresses the format-converted first and second image signals so as to correspond to a main picture and a sub-picture of a PIP image to be displayed, and synthesizes the first and second image signals into a single PIP image signal. A CRT displays a PIP image contained in the PIP image signal on a screen.

  • Patent number: 5808701
    Abstract: A video signal processing system includes a circuit for detecting the delay between a luminance signal and a color signal in a video signal, and for automatically compensating for the delay. The circuit includes a Y/C separator for separating a composite video signal into the luminance signal and the color signal, and a color difference and synchronous signals separator for separating the luminance and color signals into synchronous and color difference signals. A delay circuit receives and delays the luminance signal based on a delay control signal, and outputs the delayed luminance signal to a video signal processor, which also receives the color difference signals directly from the color difference and synchronous signals separator.
