AVIA Pro

Pro Kit Contents

The contents include state-of-the-art audio and video test signals from Ovation Multimedia, as well as industry standards from CEA and other materials from SMPTE, RPG and Genesis Microchip. The printed manual provides necessary instructions for the use of each disc.

The video test disc* provided by Ovation contains over 1,000 new test signals (with approximately 3,000 variations) and gives the video / home theater professional or enthusiast unprecedented flexibility and new capabilities. AVIA Pro not only improves the “traditional” signals but also permits functions never before possible. The variation of patterns available allows the user to select the one best suited for the job, which results in a customized test pattern generator for each project. Special emphasis during development was placed on testing and adjusting widescreen and newer technology, fixed panel display technologies such as LCD, DLP, LCOS, SXRD and Plasma. (*More specific details regarding the video test disc are available in the attached document.)

AVIA Pro’s audio test disc, also provided by Ovation Multimedia, will include sound tones for Dolby, DTS and surround sound up to 7.1. Also, SACD test tones may be included.

CEA has provided the information necessary for manufacturers to meet specifically the Standard Method of Measurement for DVD-Video Players. (Standard EIA/CEA-896.) This standard was developed based on NTSC specifications and created to make it easier to compare the functionality of DVD-Video players. The CEA disc contains a suite of test signals designed to gauge and evaluate the performance of DVD-Video players. Specifically, the standard defines test signals and test procedures for measuring different aspects of brightness and color, while helping to measure signal and audio-related characteristics.

The SMPTE portion of AVIA Pro specifically monitors equipment errors in the motion imaging industry, focusing on tests patterns for color and motion.

RPG has developed two computer programs titled Room Optimizer and Room Sizer. Both are designed to optimize the placement of listener, loudspeakers, acoustical surface treatment and room dimensions in the Critical Listening Room environment. This software (for a Windows program) is an automated process designed to take full advantage of listener and equipment placement as well as take into consideration the specific room dimensions. The details include a new methodology for determining the room size for the small critical listening spaces to achieve the flattest possible frequency response. Also, RPG provides information for minimizing acoustical distortion in project studios. This includes details relevant to acoustical issues facing design of such studios, suggestions about addressing these problems and the real-world limitations of these suggestions.

The information provided by Genesis as part of AVIA Pro includes various test patterns to optimize microchip technology and help achieve life-like visibly better images.
