TH11590EX - Signal processor for wide screen TV systems - Google Patents

Abstract

In the code / decoding system Wide screen signal For the signal of a wide screen For TV signals, the side panel chronometric data (I, Q) is transmitted (45,46,55) in the form of side bands. A pair on a carrier auxiliary signal (ASC) with a phase inversion field relative to the phase of the standard shunt carrier chrominance, side panel high frequency luminance data. (YM) except low frequency data is also sent (44,50) over the carrier-assisted shunt (ASC), but in the form of a single side band. Carrier shuffling signals help It is at the frequency of 3.58 MHz of the standard chromaticity chromaticity.

Claims (1)

1. In a wide screen TV signal processing system that consists of Main panel information And the data on the side panel, the machine contains the data processing part of the said main panel. In addition to the standard carrier chromaticity shuffling, The section for the carrier shunt modulation helps it with the side panel chronometric data. To cause the carrier signal to be modulated Of the double side band compared to the chronometric data of the aforementioned side panels and a section for contract modulation.
