Manual of AVSHD 709 Disc Calibration Patterns - BASIC SETTINGS-1
Black-Level – Most often this control will be called brightness, and you can use chapters 1 and 2 for adjustment. On the first pattern set black-level to the lowest setting where the bars numbered 17-25 flash. For the second pattern it may be more difficult to see 17 flash, and we suggest setting black-level no lower than where you can see 19-28 flash with typical viewing conditions. Some circumstances give the same black-level setting for chapters 1 and 2, and in other situations using the setting from chapter 2 serves as an acceptable compromise.
White- Level – Manufacturers may call this control contrast or picture, and chapters 2 and 3 allow for adjustments. Start by setting white- level very low so you can easily see the bars flash. Ideally you would want to see all the numbered bars 223-253 flash on these two patterns at a low setting, but in some situations the bars numbered 235-253 may never flash. Begin turning up white-level and watch to see if any bars stop flashing as you increase white -level. Generally we suggest using the highest setting available before 244 or lower disappear, but at minimum the 223-234 bars should always flash. On some displays the bars may not disappear even using the highest setting. The White Clipping description goes into further detail, and it includes other items related to white-level, such as color shift.
Color – Look at chapter 4 through a blue filter, or if available use a blue mode on the TV. Adjust the color control to find a setting where the flashing boxes labeled color most closely match the bar.
Tint – Some manufacturers may label this control hue instead of tint. Look at chapter 4 through a blue filter, or if the TV offers a blue mode that can also be used. Adjust the tint control so the flashing boxes marked tint most closely match the bar.
Sharpness – Go to chapter 5, and set sharpness low enough for no light edges to form on the black objects. On some TVs you will need to
avoid setting sharpness too low and causing the black objects to blur into the gray. If the black objects never lose definition or blur into the gray, then you may set sharpness to minimum.
Manual of AVSHD 709 Disc Calibration Patterns - MAIN MENU
Basic Settings – This video section allows you to adjust the most common user settings, and it requires nothing more than possibly a color filter. You can use the patterns to set black-level, white-level, color, tint, sharpness, and screen position. Instructions are provided in the next part of this document.
Misc. Patterns – More advanced patterns that generally do not require measurement equipment appear in this area. These items intend to address a variety of video adjustment and equipment testing applications. Later this document includes some additional information for the Misc. Patterns sections.
HDTV Calibration – This video provides instructions for configuring your display. It was originally produced as a series by HD Nation in
episodes 56 through 59, and they used an earlier AVS HD 709 version for the demonstrations. While some items, such as the APL Clipping pattern, have changed in look, the instructions remain relevant for adjusting your electronics. HD Nation had an issue with a camera in episode 58, and the effect appears in Part 3 on Color & Tint.
CalMAN – You will have the option of Windows, Fields, or APL patterns arranged for measurements with CalMAN version 4 software. Each of the CalMAN menus will also allow you to start at either chapter 1 or 2 for different measurement choices. When you select CalMAN on the HDMV the navigation changes, and you can choose one of the pattern types or use Back to exit the selection.
ChromaPure – You have the option to choose from Windows, Fields, or APL patterns arranged for measurements with ChromaPure version 2 software. After selecting this option on the HDMV version the navigation will change, and you can choose one of the pattern types or use Back to exit the selection.
ColorHCFR – You have the choice of Windows, Fields, or APL patterns arranged for measurements with ColorHCFR version 2 software for Windows. On the HDMV version you can use Back to return to the standard navigation, if you accidentally select this option and do not wish to choose one of the pattern types.
Credits – The version number for the disc and information about some of the contributing individuals and groups will appear on the right side of the screen. After selecting Credits an option to Close the overlay appears. On the AVCHD version the Main Menu selection around the center AVS HD text will display Credits.
Windows – The measurement patterns cover approximately 15% of the screen area. These are the most common patterns for taking measurements from the middle of the display.
Fields – Except for the label in the corner, the measurement area covers the entire screen. Your display and type of application will determine if field patterns are appropriate for measurements.
APL – These custom patterns intend to hold APL constant for a series of measurements. The patterns can be used to avoid automatic display brightness adjustments during measurements. Often measurement evaluations expect relative levels, and these patterns should provide relative measurements for many digital displays that might be affected by varying APL from typical windows and fields.
