This is actually on the disc itself. Select the "?" next to the name of each pattern and you get these text plates. Here they are presented for convenient reading. Some of the plates are very similar to one another because they only differ in IRE level or aspect ratio. However, pay particular...

That should get you an idea of some things that can be done with AVIA.

For those who are making Pronto macros for using AVIA, here are the Title and Chapter numbers for both the audio signals and video test patterns. GK TitleChapterAudio Test Signal 62Channel Identification (5.1) 6565 Channel Speaker Balance 63Left-Front Level 64Center Level...

DIY 6.1 using AVIA (Thankfully Home Theater Tune-up has the 6.1 tests as discrete signals) Here's how you can set the rear left, center, and right surround channels using AVIA. I'm assuming you are using a 5.1 processor and feeding the left surround and right surround line level outputs to a...

Another Grayscale Rescue (Posted as an abject reminder to stay within your limitations) The service level controls inside a RPTV can create some real problems. I'll try to help, but frankly this is very difficult to do without a professionally trained eye actually seeing the set. It appears...

Grayscale Rescue for an Overly Enthusiastic Tweaker As you've discovered, adjusting gray scale is not an easy matter. That is why most people leave it to professional ISF calibrators who can tune it in very tightly. At the very least you need an optical comparator or D65 light source against...

Reply re Scaler Question If I understand the question correctly, the problem is that the AVIA resolution patterns don't seem to look different despite changing the HTPC scaling resolution up and down. This seems puzzling, but is a natural consequence of your equipment's resolution. Despite...

Another Grayscale Answer for a User Let?s first review how the NTSC picture is best conceptualized so the calibration process makes sense. Think of the image as a black and white picture upon which is overlaid colorization information. This is represented on the signal lines as Y (luminance)...

Yes the forums are a wonderful resource. The immediate feedback, ability to reach many people at once, addition of information by others, and correction of errors & omissions are why I prefer to answer questions in the open forums rather than private mail or messages. Writing a single person...

Some tips on setting beam and optical focus very well. As mentioned above, display a dots pattern. Set dynamic astigmation controls to center position. This allows you to set the magnets to do most of the work and just fine tune later with the dynamic controls. Binoculars are very handy but...

Blue Defocus Defocusing the blue gun increases the efficiency of that gun and allows greater blue output. This is not an issue with direct view sets, but projection CRT displays often require some degree of blue gun defocus to achieve a grayscale which tracks correctly from black to white...

Most people obtain AVIA for calibrating their systems, but very few realize how a test disc helps separate displays from each before purchase. Ask nicely. You may get a chance to objectively evaluate a display instead of relying on how the store set up to make certain displays look better...

Using AVIA Phase Tests to Fine Tune Speaker Distance and Delay AVIA's speaker phase testing signals are also useful for very accurate adjustment of speaker delays and distances. You'll need an analog RS SPL meter set to fast response in order to take advantage of this tidbit. This may seem a...

Setting Speaker Level with AVIA Let's go back and examine what is happening when setting a system to reference level. You are attempting to set sound reproduction level such that for any given sound you produce the same loudness as was heard in a mixing studio whose system is also set to...

Should I Set my DVD Player to Enhanced or Normal Black? NTSC video signal levels are commonly measured in IRE units which can be converted to voltage levels. The conversion isn't important to this discussion. IRE units are easier to use so we all tend to refer to signal levels in IRE rather...

Black Level Clamping (aka DC Restoration) Why does the appearance of black vary with different scenes? The appearance of "black" often varies depending on the remainder of the image on consumer grade video displays. Another more technical term for how stable black remains is "DC...

Black and White Level Adjustment Let's first examine what the black level (brightness) and white level (contrast) controls actually do inside the set and the performance limitations that set the bounds within which you should keep the controls. Within the television, there are video...

AVIA Calibration Tip #6 -- Subwoofer Test Tones and Bass Management AVIA users have occasionally wondered why nothing comes out of their subwoofers during AVIA's subwoofer setup test tones unless their speaker sizes are set to "small." The test signals are working as they should, but AVIA is...

AVIA Calibration Tip #5 -- Resolution Patterns Look in your local newspaper advertisements and you'll see amazing claims of 800 to higher lines of resolution. Unfortunately, you'll be hard pressed to find a salesman who understand how those numbers were measured or how they relate to the...

AVIA Calibration Tip #4 -- Color Decoder Check NTSC video signals must be separated, decoded, and matrixed to form the final red, green, and blue signals which drive the display. Professional grade displays accurately decode the color signals and render colors correctly. However, consumer...

AVIA Calibration Tip #3 - Sharpness Pattern NTSC video carries most of its resolution in the luminance portion of the signal. Onto this is overlaid lower resolution color information to yield the final picture. By doing this, the designers of the NTSC system were able to provide an image which...

AVIA Calibration Tip #2 - Blue Bars, Red Bars, Green Bars Color bars are useful for checking the proper function of color decoders in a display. With NTSC displays one can vary the saturation (amount) and hue (phase relationship) of the display. Ideally, the display is adjusted to recreate the...

AVIA Calibration Tip #1 - Needle Pulses + Steps Video Test Pattern Needle Pulses + Steps Test Pattern At first glance, one mistakes this pattern for a traditional Needle Pulse pattern, but there are important changes in the pattern which make it more useful. Most obvious is the addition of a...

The disc has quite a few additional patterns. Take some time and read through the explanations for each one by selecting the "?" next to each pattern name. You might pick up a few pointers along the way. There was once an archive of some AVIA related postings. It seems to have gone away so I'll...
