System Configuration

Once the settings have been made on the main video setup screen, you may either return to the main setup menu or proceed to the two Advanced Configuration setting menus. The options on those pages are set by your choice on the SOURCE TYPE line as shown above, but you may wish to change one or more of the set- tings to customize video presentation.

To return to the MAIN MENU, press the ¤ Navigation Button DF so that the on- screen ➞ cursor is pointing to BACK TO MASTER MENU and press the OK/Enter Button E on the TC 30 or the Set Button Q.

To change the settings on the ADVANCED CONFIGURATION menus, press the ¤ Navigation Button DF so that the on- screen ➞ cursor is pointing to ADVANCED CONFIG SET and press the Set Button Q. The first page of the ADVANCED CONFIGURATION menus (Figure 6a) will appear on-screen.

Advanced Configuration Settings

The Advanced Configuration Settings may be used to change the individual items that make up the default profile for each video input. You may change none, one or as many of the settings as you wish to create the on-screen image that you prefer. As with all of the video settings, you can't "hurt" anything by experimenting with the set- tings and while the defaults represent the result of extensive lab testing with a variety of display types, input sources and test signals, there is no "right" or "wrong" setting other than the ones that look best to you.

The settings available on Page 1 of the ADVANCED CONFIGURATION menus (Figure 6a) are all On/Off settings. When the page is shown, use the ⁄/¤ Navigation Button DF to move the on-screen➞ cur- sor next to the line for the setting you wish to change. Then, press the ‹/› Navigation Button DF to turn the setting on or off.

The settings available on Page 1 of the

ADVANCED CONFIGURATION menu are the following:

NOISE REDUCTION: When this setting is turned on, there is a reduction in the video noise that is often present in analog input sources.

X-COLOR SUPRRESSION: When this setting is on, there is a reduction in the cross- color interference that typically appears in com- posite video sources as moiré in finely detailed objects.

DCDi INTERPOLATION: DCDi stands for Directional Correlation De-interlacing, and it is a Faroudja technology that examines each pixel for the optimal direction from which to interpolate the video information with regard to local edges. This adaptive process prevents the appearance of staircasing and the jagged edges that are often visible with other means of de- interlacing.

FILM MODE DETECT: When this setting is on, special circuits are used to detect the presence of film-originated material so that the original film-frame sequence may be recovered by weaving together the appropriate video fields.

FILM MODE EDIT DETECT: When this setting is on additional processing is applied when film-based material is detected so that any disruption in the frame sequence of film- based material due to video edits or the overlay of video text over film is compensated for by processing before artifacts such as feathering may appear.

FLESHTONE NOISE REDUCTION: When this setting is on, the processing is adapted to preserve the detail in faces and flesh tones while reducing noise in the total picture.

COMPOSITE VIDEO ENHANCE: When this setting is on, composite video signals are processed at the level set in the main Video menu to adjust the high frequency content of the signal. This setting acts on the vertical and horizontal as well as the luminance and chromi- nance signals to offer what will appear as enhanced depth in the picture as well as greater small object detail.

When all settings on this submenu page that require adjustment have been made, use the ‹/› Navigation Buttons DF to move the on- screen ➞ cursor next to PAGE 2 and then press the OK/Enter Button E on the TC 30 or the Set Button Q. to move the next page of Advanced Configuration settings, or move the on-screen➞ cursor next to the TO VIDEO MAIN line to return to the main Video menu.

The settings available on Page 2 of the ADVANCED CONFIGURATION menu (Figure 6b) are the following:

TEST VIDEO: The test signals that are called up on this line are designed for use in factory setup of the AVR 745’s video processing circuit and they are not designed for user adjustment of any controls on your video sources, on your video display or on the

AVR 745 itself. You may bypass this setting line unless you wish to view the signals, but remem- ber that they are not designed for any consumer use.

To view the test signals, with the on-screen ➞ cursor next to the TEST VIDEO line, press the ‹/› Navigation Buttons DF to select one of the test signals described below, and then press the OK/Enter Button E on the TC 30 or the Set Button Q to activate the test signal. The test signal will remain on the screen for the length of time selected in the ADVANCED SETTINGS menu for the on-screen menus, as explained on page 53. The four test signals are:

Color Bars: These are a variation of tradi- tional split-field color bars used to check the internal settings for luminance/chrominance voltage levels with respect to the eight basic colors.

Triangle Fixed: This test signal puts two opposing triangles on-screen, with a black triangle on the right and a white triangle on the left to test aspects of the pull-down logic soft- ware.

Triangle Flashing: This test signal also puts two opposing black and white trian- gles on the screen, but it flashes them at a high frame rate to test the 3/2 pull-down edit detec- tion and other aspects of the processor and interpolation software.

Ramp/Square: This complex pattern uses a variety of fixed and pulsating gray-scale tests to test different aspects of the 3/2 pull-down edit detection and other aspects of the proces- sor and interpolation software.
