A technique for detecting three modes of video input signal and outputting a vertical sync signal based on the input signal. In a first mode, a standard video signal is received and a line counter is used to decode and output the vertical sync. In a second mode where a non-standard signal is received, line counter cannot be used, but a vertical sync is detected and output. In a third mode, no video input signal is received, yet a vertical sync is output in free-running mode so that a blank screen is displayed.

A color comb filter ( ), video decoder ( ) and method for separating chroma (U,V) and luma (Y) signals from a composite video signal ( ). The comb filter ( ) includes circuitry ( ) for generating color filter selections for filtering a chroma video signal ( ) and control logic ( ) for determining the filter selections based on color boundary properties of the chroma video signal (U,V). The video decoder ( ) includes a comb filter ( ), a demodulator ( ), low pass filter ( ), a remodulator ( ) and a subtractor ( ). The filtered, remodulated chroma signal (U ,V ) is subtracted from the composite video signal ( ) to produce a luma signal absent hanging dots and false colors.

Caller Select allows the user to select incoming telephone numbers in the Caller ID that he wishes to receive and will ring the telephone all other numbers will be rejected and not allowed to ring the telephone Numbers may programmed either by pressing an enter switch during a review controlled by a switch or by going into the program mode by pressing a mode switch and pressing buttons on a touch tone phone The operation is controlled by software running in a low power microprocessor The Caller Select mode may be turned off by a switch which in display of the Caller ID only and ringing by all calls.

In accordance with an embodiment of the present invention a microprocessor in the horizontal phased lock loop reads the horizontal timing with respect to the sync input and provides an increment incto the horizontal discrete time oscillator to make corrections in its timing to maintain lock to the sync input. The horizontal discrete time oscillator output is used to produce a pixel clock which drives the color discrete time oscillator in a color phased locked loop. A microprocessor reads a phase error between the color burst input and the color local oscillator frequency and writes an increment incto the color discrete time oscillator to maintain lock to the color burst. The horizontal phase locked loop adjusts incthat varies about nominal increment (nom_inc) by Δh. The feed forward error correction for the adjustment to the color discrete time oscillator is the nomimal increment (nom_inc) and a feed forwarded scaled version of Δh.

A phase-locked loop is provided which is operable to lock the sampling clock (pixel clock) to the incoming horizontal sync pulse contained within composite video information. Given the input signal is a VCR signal or a normal noise-free signal, there exists two modes of operation, coarse lock mode and fine lock mode, which are used in controlling the phase-locked loop. In the coarse lock mode, coarse corrections are made to a horizontal discrete time oscillator so that a fast lock may be achieve using the fine lock mode. Coarse corrections are based on a normalized sum of weighted pixels collected within a narrow gate window. Lock is achieved when the falling edge is centered within the window. Given the input signal is a television signal having noise, there exists one mode of operation where the flat window phase detector is used instead of coarse lock mode to bring the sync edge to fall within the window, where the flat window normalization constant is tuned.

A SECAM decoder and an FM modulator therefor are disclosed, in which a demodulated color signal is provided to indicate deviations in the frequency of modulated color information from a nominal subcarrier frequency. The demodulator comprises numerator and denominator filters operating on the modulated color information, and a divider providing a ratio result by dividing the numerator filter output by the denominator filter output. The demodulator may include two sets of numerator and denominator filters offset in phase from one another, where one of the two sets is selectively employed in order to mitigate divide-by-zero problems. Also disclosed are methods for demodulating digitized FM color signals in a SECAM decoder.

In one embodiment, a method for processing a video signal includes: (1) receiving and storing luminance and chrominance information for each pixel in a first portion of the signal; (2) receiving luminance and chrominance information for each pixel in a second portion of the signal; (3) determining an estimated motion vector for each particular pixel of the second portion by comparing the luminance and chrominance information of the particular pixel to the stored luminance and chrominance information for one or more pixels in a search area of the first portion to determine a pixel in the search area that most closely matches the particular pixel and determining the estimated motion vector according to the particular pixel and the most closely matching pixel; (4) using the estimated motion vector to access the chrominance information for the most closely matching pixel; (5) using a three-dimensional comb filter to filter the chrominance information for the particular pixel and for the most closely matching pixel to determine three-dimensional filter output chrominance information for the particular pixel; (6) receiving the three-dimensional output chrominance information and if the chrominance information for the particular pixel matches the chrominance information of the most closely matching pixel within a specified tolerance, using the three-dimensional filter output chrominance information to determine output luminance information for the particular pixel; and (7) providing the three-dimensional output chrominance information and output luminance information for the particular pixel for displaying the particular pixel.
