  • Method and system for digitally decoding an MTS signal
    Publication number: 20040101143
    Abstract: A method and system is disclosed for digitally demodulating an analog signal. In one example, the analog signal contains a L+R signal, a L−R signal centered around a carrier signal, and a pilot signal. An exemplary system for digitally demodulating such a signal includes an analog to digital converter, three digital filters, clock reconstitution circuitry, L−R signal recovery circuitry, and channel recovery circuitry. The analog to digital converter converts the analog signal into a digital signal. The three filters separate the L+R signal, the pilot signal, and the L−R signal from the digital signal. The clock reconstitution circuitry reconstitutes a clock signal from the separated pilot signal. The L−R signal recovery circuitry recovers the separated L−R signal using the reconstituted clock signal. The channel recovery circuitry recovers a left channel signal and a right channel signal from the separated L+R signal and the recovered L−R signal.

  • Multichannel television sound stereo and surround sound encoder suitable for use with video signals encoded in plural formats
    Patent number: 6445422
    Abstract: Method and apparatus for generating a composite audio signal clocked to a selected frequency from left and audio input signals. A video/audio signal generator transmits the left and right audio input signals, together with a video signal having a horizontal synchronization signal embedded therein. If copy protection has not been applied to the video signal, the embedded horizontal synchronization signal will have a frequency of 15.734 KHz. If applied to the video signal, copy protection techniques will shift the frequency of the horizontal synchronization signal. To avoid distortion of the composite audio signal, a switch configured to selectively couple the video signal or a secondary video signal generated by an internal video signal generator to an audio signal processor which generates the composite audio output signal from the left and right audio input signals. Embedded within the secondary video signal is a horizontal synchronization signal having a frequency of 15.734 KHz.
