Applications
- Master or Slave Sync Generation in HDTV Production Environment
The SPG1000 is a multiformat HDTV Sync Generator. Designed to support the HDTV production environment, the SPG1000 also provides a genlock function and an external clock source for the TSG1000 Series Programmable and HDTV Generators.
Sync Generator
The SPG1000 provides master and slave sync generator capabilities for multiformat HDTV production environment. Independent selection of output and genlock input formats (see Table 1), timing advance and delay controls, and timing presets provide flexibility in system integration. In the absence of an incoming reference signal, the SPG1000 automatically switches to its own stable internal reference.
Test Signals
The SPG1000 test-signal complement is designed to support the operational requirements of the typical postproduction environment. These include picture-monitor setup signals and color bars for tape leaders.
The SPG1000 test-signal set includes:
- 100% color bars
- Pluge with white clip indicator
- Black, grey, white, and red fields
- Convergence pattern with 5% overscan markers
- 5-step grey scale
- Timing signal with 1-ns markers
Test signals are provided in GBR and Y, PB, PR format.
Controls and Indicators
All SPG1000 operating selections and timing adjustments may be made from the front panel. Once all selections are made, the front-panel controls may be disabled to prevent accidental changes to user settings. The vacuum fluorescent front-panel display provides information on the front-panel function currently selected.
Remote Control
The SPG1000 will provide RS-232 or ground closure remote control of most front-panel functions. In addition, front-panel settings may be stored and recalled through the remote control port.
