ADVANCED FEATURES 49ENGLISHVideo Adjustments Advanced FeaturesVideo AdjustmentsThe AVR 347 includes sophisticated DCDi byFaroudja video processing that deliversenhanced video quality, even for older analogvideo source components, as well as upgradedon-screen displays. When upscaling videomaterials from a lower resolution to a higherone (the AVR 347 upscales to a maximum of720p), the processor is adding pixels to theoriginal image. Sometimes when convertinginterlaced video (displays all odd rows then alleven rows of the frame) to progressive-scanvideo (displays all rows at once) and increasingthe resolution, the interpolation of new pixelscan cause jagginess, or a staircase effect, atedge transitions, such as the stripes in anAmerican flag. Faroudja engineers developed theDCDi (Directional Correlational Deinterlacing)algorithm to ensure that the additional pixelsfollow the edge, virtually eliminating thejagginess and enhancing upscaled images.The video processor is set at the factory toautomatically provide the best picture as itdetects the capabilities of your video display andthe incoming source video signals. However, youmay experiment with the Video Setup menuadjustments to try to improve the picture further.The Video Setup menu includes a reset feature inthe event you wish to return to the factorydefaults and try again.To access the Video Setup menu, press the OSDButton L to display the menu system, andnavigate to the Video tab. Press the Set ButtonF to access the Video Setup menu, shown inFigure 31.Figure 31Output Format: This setting is used to specifythe resolution of the AVR’s video output as 576i,576p or 720p.When the HDMI Output is active, 576i output isnot available. If you select the 576i setting andthe video display is capable of 720p resolution,the AVR will automatically select the higherresolution. If the display is not capable of 720presolution, the AVR will select the 576p setting.If your source signal is 1080i or 1080p, it will bepassed through to the HDMI Output as is, butyou may not select that output format on thisline, as upscaling to these resolutions is notsupported. If you are using the ComponentVideo Monitor Outputs, you will not be able toview 1080p materials, but 1080i sources will bepassed through. In any event, when the sourcesignal is 1080i or 1080p, the semi-OSDmessages will not appear, including the volumebar. Full OSD displays will appear, but at a lowerresolution.Viewing Preference: This setting allows you toselect factory-predetermined picture setting thatis optimized for various types of programmaterials. You will notice that when you changethis setting, the Sharpness, Brightness, Contrastand Color settings will change accordingly. Theavailable options are CINEMA, SPORT, NATUREand VIVID.Sharpness: You may adjust the Sharpnesssetting from 0 to 100 in increments of 4-5 units.We recommend leaving this setting as low aspossible, as contrary to what you might expect, aless sharp image can appear clearer on screen.In addition, increasing the Sharpness requiresadditional video processing, which may lead toloss of sync with the audio or visual artifacts.However, there is no harm in experimenting withthis setting.Brightness: This control adjusts the level atwhich black is delivered. We recommend leavingit at its factory setting, although there is noharm in experimenting if you are using a testsignal.Contrast: This control adjusts the differencebetween black and white in the picture. Werecommend leaving it at its factory setting,although there is no harm in experimenting ifyou are using a test signal.Color: This control adjusts the hue of the colorsin the picture, and may be set between 0 and100. Select a setting in which people andobjects on screen look natural. There is no“recommended” setting, and no harm inexperimenting.Reset: If you wish to return the video settingsto their factory defaults, select this line and pressthe Set Button F.Advanced FeaturesThe AVR 347 is equipped with a number of ad-vanced features that add extra flexibility to theunit’s operation. While it is not necessary to usethese features to operate the unit, they provideadditional options that you may wish to use.Front-Panel-Display FadeIn normal operation, the front-panel displaysand indicators remain on at full brightness,although you may also dim them or turn themoff as shown on page 46. As an additionaloption, you may also set the AVR so that thedisplays are on whenever a button is pressed onthe front panel or remote, but then fade outafter a set period of time.To set the front-panel displays to the Fade mode,press the OSD Button L to bring the mainmenu to the screen. Press the ⁄/¤Navigation Button D so that theSystem -tab is highlighted in white, andpress the Set Button F to enter theSYSTEM SETUP menu (Figure 32).Figure 32With the SYSTEM SETUP menu on yourvideo display, press the ⁄/¤ NavigationButton D so that the blue cursor bar is high-lighting the VFD Fade Timeout -line.Next, press the Set Button F, followed bythe ‹ /› Navigation Button E so thatthe amount of time that you wish the displays tofade out after a button is pressed is shown.Once this time is set and the unit returned tonormal operation, the displays will remain on forthe time period selected whenever a button ispressed on the front panel or remote. After thattime they will gradually fade out, with theexception of the lighting surrounding theStandby/On Switch 3, which remains on toremind you that the AVR is turned on. Note thatif the displays have been turned completely offusing the Dim Button, as shown on page 46, theFade function will not operate.
