Operation, cont’d Operation Front Panel Controls and Indicators All of the scaler’s controls are on the front panel (figure 3-1). Front panel LEDs provide graphic indication of some of the basic system functions. For more complex tasks, such as system configuration, the scaler has a menu system that is operated using the front panel buttons and displayed on the output monitors (figure 3-2).
If a different input is selected, see 1 , the switching action deselects the freeze function, the frozen image is lost, and the Freeze LED returns to its unlit state. Freeze has no affect on input 4 when it is passive (unscaled). Audio controls 4 Volume and buttons — The Volume buttons regulate the volume level of the selected audio input. Use the Volume buttons to increase and decrease the audio level for the current input.
Operation, cont’d 8 Enter button — The Enter button either activates a submenu or function in the IN1404XT menu system or saves a changed value. See Front Panel Operations in this chapter for details. The effects of all adjustments are visible on the screen or audible on the audio output, but they are temporary unless saved. The adjustments return to their previous settings when the adjustment screen exits by either a timeout or the operator pressing the Menu button.

Operation, cont’d Signal Format screen The Signal Format screen shows the video format (such as RGBHV, component video, or S-video) assigned to each input and provides the ability to change the video format assigned to each input. It is critical that the signal format selected is correct. If the wrong input circuitry is selected for the input signal, the scaler will not function properly and will display either a distorted image or no image at all.
• Standard — For standard 1.33 inputs (also known as full screen). • Anamorphic — Provides vertical image squeezing to accommodate anamorphically enhanced DVDs (1.85). • Wide screen — For wide 1.78 inputs (letterbox). • Wider screen — For wider screen 2.35 inputs (narrow letterbox). • Tomarama — Expands a 16:9 signal to fill a 4:3 screen (1.78). As it expands the signal, it cuts off the left and right sides, simulating the movie aspect ratio “Cinemascope”.

RGB video on input 4. Input 4 must be configured as a passive (unscaled) to serve as a time reference for seamless switching. If input 4 is not already configured as passive, the scaler automatically reconfigures the input when you turn seamless switching on. Use the Menu or button to highlight “On” or “Off” and press the Enter (and save) button to turn seamless mode on or off. Size screen The Size screen displays two status indicators that show the horizontal and vertical size settings.
Operation, cont’d The VTR001 CM that receives the TP output can receive RGsB signals from the scaler. However, the red, green, and blue video signals’ black levels are not clamped to a 0V reference, as for RGBHV or RGBS. For most displays, this is not a problem. On some displays (such as some LCD displays) however, the black levels of the red, green, and blue signals may change as the average picture level changes, resulting in an unacceptable image.

in common”. Seamless switching only occurs between the passive channel 4 input and the channel in common input. Switching between input 4 and a non-channel in common input occurs during the vertical interval of input 4. There is a slight delay without blanking while the new input syncs to input 4 and becomes the new channel in common input. When you switch between two scaled inputs without going through input 4, the switch is not seamless. A brief blanking interval is seen on the output.
Operation, cont’d To change the output aspect ratio of most DVD players: 1. Enter the DVD player’s setup or action menu while the disc is stopped. 2. Select the 16:9 aspect ratio.

Operation, cont’d Advanced Input submenu options Figure 3-13 shows the submenus that are available from the Advanced screen. The scaler automatically adjusts for different input and output modes. However, if the input signal has slightly different timing or is non-standard, some settings may need to be manually adjusted.
Vertical Blanking Total Lines Blanking Area Active Area Active Lines Horizontal Blanking Active Pixels Total Pixels Figure 3-14 — Advanced input settings • Horizontal blanking — Set from the Blanking submenu. The number of pixels per line that are inside the blanking area to the left of the active area (including the horizontal sync width and the horizontal back porch. • Vertical blanking — Set from the Blanking submenu.
Operation, cont’d Vertical Blanking Active Blanking Area Active Area Horizontal Blanking Figure 3-15 — Incorrectly blanked image Similarly, if the vertical blanking adjustment is set to less than the amount of actual blanking, the IN1404XT starts scaling before the first line of the active image. This early scaling results in a blank border on the top and cropping on the bottom, and looks as if the image is shifted down. Press the and buttons to shift the blanking period vertically on the screen.
Blanking Area Incorrect Active Area Active Lines Active Area Active Pixels Figure 3-16 — Incorrect active area setting Similarly, if the number of active image lines that the scaler is set to scale is set to less than the amount of actual active lines that are input, the IN1404XT only scales the set active area and will skip some of the input lines. This early end to the scaling process results in an output with fewer lines than it should, and looks as if the image is stretched vertically.
Operation, cont’d Press the and buttons to increase and decrease the number of active pixels. Press the and buttons to increase and decrease the number of lines. Press the Enter button to save the changes and return to normal system operations. Total pixels adjustment There are several methods to determine the correct value to use in the total pixels variable. Usually, the best method is to use the input signal specifications.
• Interlaced — Some video sources output interlaced video at rates that the scaler interprets as progressive scan mode. This option lets you force the scaler to recognize it as interlaced video. • Swap Fields — Swaps the interlaced fields (if necessary). Although this option can be turned on when the input is progressive, it has no affect on progressive video. • Invert Sync — To invert the sync polarity (if necessary).
Operation, cont’d Troubleshooting This paragraph gives recommendations on what to do if you have problems operating the scaler, and it provides examples and descriptions for some image problems you may encounter. The following tips may help you in troubleshooting. 1. Some symptoms may resemble others, so you may want to look through all of the examples before attempting to solve the problem. 2.
