The LC7455A/M extracts the closed caption signal superimposed on a video signal during the vertical return period and, under the control of a clock signal provided by the decoder IC, transfers that signal to the IC (usually a microcontroller) that decodes the closed caption data. The LC7455A/M supports four operating modes. Modes 1 and 2 can be used for XDS. In these modes, the LC7455A/M,in combination with the decoder IC (microcontroller),extracts the caption signal superimposed on field 2 and uses it for NTSC VCR functions such as the automatic time and date setting function. In modes 3 and 4, the LC7455A/M, in combination with the decoder IC (microcontroller), extracts the caption signal superimposed on fields 1 and 2 and uses it for NTSC TV applications (mode 3) or PAL TV applications (mode 4).
