EDTV2 IDENTIFICATION SIGNAL DETECTOR DESCRIPTION
The M52393 are integrated-circuits of a semiconductor, developed especially for EDTV2 identification signal detection. In contrast to such ICs, few products on the IC market had the simple function of detecting identification signals. For that purpose, many manufacturers had to combine discrete components (nonICs) with gate arrays. There was a great demand for ICs that enabled cost reduction. In order to satisfy demand, we have developed the EDTV2 identification signal processing ICs that include all necessary capabilities for detection (synchronous signal separation, line counter, filters, level detection, and bit judgment). The use of such ICs reduces parts, eliminates the need for complicated adjustment, and enables easy handling and cost reduction. Outline 16P4 16P2N-A

FEATURES
*
* * * *
All necessary detection capabilities, such as a synchronous signal separation circuit, are integrated into a single microchip. The use of the microchip can simplify application circuits, and eliminate the need for adjustment. (Only two inputs are provided: video signal input and fsc signal input.) Our original method is used for distinguishing EDTV2 identification signals from normal video signals. Therefore the accuracy of identification is improved. The detection level is adjustable. The microchip operates on a single supply voltage of 5V. Two types of packages are provided: DIP with a lead pitch of 2.54mm (M52393P); and SOP with a pitch of 1.27mm (M52393FP).

In a case an EDTV2 identification signal (or an equivarent one) is detected a couple of times during three lines of 21 to 23 (line 284 to 286), the output will be Lo (a standard signal). On the other hand, the output will be Hi (an EDTV2 signal) through the ID signal is detected a couple of times during the three lines. The detection is performed once a field. The choice between Odd or Even is difficult. (effective data : 8 fields/ 8 frames)

EDTV2 IDENTIFICATION SIGNAL DETECTOR METHOD OF DETECTION
A line part (refer to Fig.1) An EDTV2 ID is inserted into the line 22 (line 285), therefore the IC detects during 3lines (including before and after 2 lines of the line 22). A field contains the ID signal in its appropriate lines, whitch results in an EDTV2 signal. In a case the ID signal is detected a couple of times during three lines, a signal is regarded as a standard signal not an EDTV2 considering the correlation between 2 or 3 lines (pin 7 is grounded). On the other hand, the line correlation is off by opening the pin 7. In this case, the signal is regerded as an EDTV2 even though the ID signal is detected a couple of times during the three lines. A frame mode The pin 10 is grounded (0V). The detection is performed once a frame; once a Odd field or once a Even field. It takes more than 267ms (8 frames) for the distinction. Note: The alternatvie of Odd or Even field is difficult because of no field distinction. A field mode The pin 10 is opened (2.5V). The detection is performed once a field. It takes more than 133ms (4 frames) for the distinction. A field part (refer to Fig.2) In a case the ID signal is detected in 8 consecutive fields, a signal is regarded as an EDTV2 one and the pin 9 outputs high. However it can not be detected consecutivelly, a signal is not an EDTV2 one and the pin 9 is low. Detecting timing is varied in following 2 modes.
