Signal Flow

QUADRIGA•Video Machine Control system queries the video playback equipment for status and diagnostics information based on SMPTE 273M-2003: Status Monitoring and Diagnostics Protocol (SMDP). SMDP is derived from the Sony Interactive Status Reporting (ISR) via the VTR RS232C Bit-Serial Digital Interface. Whenever video frames fail to decode properly on the playback device, specific report entries with timestamps are made in the Quality Report. The amount of error correction happening during machine playback is monitored, giving the operator an immediate indication on the video tape quality during the process

The QUADRIGA•Video Multi-Viewer provides the digitization operator all four video signals along with independent audio metering and vector-scope tools configurable to each A/V stream. This allows a visual display of all base-band signals at a glance. In addition, QUADRIGA•Video provides an optimized per-stream interface to control and visualize each VTR system; its signals, machine control and numerous quality control metrics supplied from the analysis engines’ signals.
