Programm Module DV Delay

Both TELE and TELE Info systems for playback automation and graphics overlay contain the additional free of change program that allows to delay the pass-through signal for specified period of time. The maximum delay period depends only on the capacity of the used Disk Arrays.

The technical implementation of signal delay is the following. The pass-through TV signal is fed to the input of the hardware converter Analog-DV* via S-Video. Then converted DV-stream comes to PC through IEE 1394 interface. The delayed signal in such a way appears to be the input signal for TELE 2.2 system. Thus the insert of all video clips, logotypes, horizontal crawls etc is carrying out not by overlying the live TV signal that comes to the input of the Stream ALPHA Plus PCI-E card but using the delayed signal from Analog-DV converter.

* We recommend to use Canopus ADVC 100 (110) converter. The device has NTSC (525/60), PAL (625/50) S-Video, composite analog inputs / outputs. The converted DV-stream is transmitted to a computer via IEEE 1394. ADVC-100 (110) provides a stable synchronization when converting analog signal to digital, assuring perfect audio and video synchronization. Since you only need the input TV signal, ADVC-55 will be sufficient. Likewise, you can use any DeckLink card for the input signal capture (for analog signal, DeckLink Intensity card will be sufficient).
