2.1.1 Analog Video

Six analog video sources together with their sync- and clock signals can be connected to two 15-pin D-connectors. A

2:1 selector routes these signals to three video A/D converter and the logic for processing of the sync- and clock

signals.

Three video sources can be recorded at the same time, as long as they are synchronous to eachother.

Cameras can be connected in master- or slave mode. When connected as master, the sync signals are recovered from

the analog video or fed in as separate TTL signals. When in slave-mode, the sync-signals are provides by the camera-

interface of INSPECTA. The sync-signals conform to either the RS-170 ( 525 lines ) or CCIR ( 625 lines ) standard.

Either in master as in slave mode the pixel clock can be driven from one camera ( one input per connector ) or from

the INSPECTA. The INSPECTA provides up to five discrete clock frequencies: 12.5Mhz, 25Mhz, 14.1875Mhz,

28.37Mhz oder 20Mhz. One quartz-oszillator is socketed, so that oszillators with other frequencies can be plugged in.

If, with master-mode, no clock is available, one of the five internal oszillators can be synchronized to the falling edge

of the recovered horizontal sync signal. Per connector one of three video signals or one additional composite sync pin

can be selected as sync source.

The phase-jitter of the synchronized clock with respect to the horizontal sync is ¼ clock max. Synchronization is

repeated every video-line. Within the line, the clock jitter is negligible.

Additional functions of the camera ( e.g.: shutter, integration )are controlled by four independant TTL- signals. Each

connecter P1 and P2 has ist own LS-TTL compatible buffer for these signals.
