The disc is structured into multiple chapters of tutorial and setup information, followed by a chapter filled with advanced video and audio test signals. A bonus section contains a video montage of down-converted high-definition live-action material selected for critical evaluation of screen setup.

Basic Test Patterns
The basic video test signals can be used without test equipment and require only the use of color filters, which are supplied. While, ideally, an inexpensive sound-lever meter should be used with many of the audio test signals, in most systems you can get by using just your ears as the test instrument. Easy-to-navigate menu access is provided to all signals and instructional materials.

Avia II Advanced Video Test Patterns
Containing a generous subset of the exhaustive set of video setup, calibration, and evaluation signals from Ovation Multimedia's Avia Pro, the Avia II Advanced Video Test Pattern section contains most of the Avia Pro patterns that can be usefully utilized without video test equipment. Special emphasis was placed on evaluating and adjusting widescreen and newer technology, fixed panel display technologies such as LCD, DLP, LCOS, SXRD, and Plasma. Newly introduced from the first Avia disc are motion tests, including several for player/screen behavior with mixed progressive/interlaced signals and for color-wheel artifacts with color-sequential displays (mainly DLP). Gamma, an extremely important charactersitic for flat-panel technologies, can be estimated by Avia II tests.

Reference Level Accuracy and Resolution
Like the signals in Avia Pro, AVIA II achieves reference-quality signal accuracy by starting as directly digitally generated 480P 2/3 pull-down, 4:4:4 test signals in native widescreen DVD resolution. This avoided any signal level shifts or resolution changes which might have occurred with analog signal acquisition or HDTV downconversion.

The pattern masters were compressed with custom MPEG2 encoders whose signal accuracy and quality were optimized through close collaboration between Ovation and the encoder manufacturer.

One Size Doesn't Fit All
Sometimes, commonly available test patterns are not ideal. AVIA II includes variations of patterns to allow selection of one just right for the job. Traditional color-bar adjustment, for instance, are often hampered in consumer sets by screen overscan. The primary color-bars test pattern in Avia II is windowboxed so that no color bar is cut off or partially visible. And instead of only being able to check black level stability at one APL, the AVIA II user can select the APL using the freeze frame capabilities of a DVD player.
