Title: Standard/nonstandard discriminating apparatus for television signal
Inventor: OTSUKA KYOKO
IPC: H04N5/04
Filed: 2001-10-24
Abstract: PROBLEM TO BE SOLVED: To accurately discriminate whether an input television signal is a standard signal conforming to its specifications or a non-standard signal not conforming to the specifications. SOLUTION: In a discriminating apparatus 1, a vertically synchronized horizontal phase value detector 21 inputs data VθH indicative of a phase in a horizontal line at timing of a start edge in a vertical synchronizing pulse. Since a counter 17 starts its counting operation for a system clock with the start edge of a horizontal synchronizing pulse, its counted value indicates a phase in the horizontal line. A counter 24 counts the number of horizontal synchronizing pulse generated in one field. A subtraction circuit 23 finds a difference (VθH- H') between a current field θH and a previous field θH. A discriminator 25 calculates the number of horizontal lines of the previous field on the basis of the difference (VθH- H') and the number of horizontal synchronizing pulses in the previous field.  The discriminator determines whether or not the calculated horizontal line number of the previous field lies within an allowable range based on specifications.
