Title: Multiple code readout device
Inventor: AMINO TADASHI
IPC: H04N19/895
Filed: 1996-08-29
Abstract: PROBLEM TO BE SOLVED: To provide a multiple code/readout device which allows to prevent a wrong code from being outputted even when part or all of two codes are absent. SOLUTION: Two codes multiplexed to a composite video signal are detected by a comparator 32 and converted to parallel data by a code incorporating circuit 34. The first code detected at first is supplied to a comparison circuit 42 through a register 38 and the second code detected next is supplied to the circuit 42 through an inversion circuit 40. Whereas the circuit 42 supplies a high-level signal to a register 46 when the first code coincides with the inversion code, otherwise it supplied a low-level signal to the register 46. The register 46 outputs the first code supplied from the register 38 when given a high-level signal but it outputs the first code already stored when supplied with a low-level signal. By this, only the first code which coincides with the inversion code is outputted and thereby outputting of wrong codes is prevented.
