... STV2110A Automatic Standard Identification The circuit is alternatelyforced in eachmode during two fields (PAL mode, SECAM mode disabled or SECAM mode, PAL mode disabled). If PALsignal is identified, the alternate PAL/SECAM sequency is locked in PAL mode. To have a SECAM identification, the circuit must memorizes a first SECAM identification, than test the PAL mode and confirm a second SECAM iden- tification ...
