GUIDE TO INSTALLATION AND OPERATION 1 DNR-101i Digital Noise Reducer DNR-111i Digital Noise Reducer with MNR 1.1 Introduction The DNR-101i and DNR-111i provides Digital Video Noise Reduction of SDI video signals for incoming feed and compression pre-processing applications. The DNR-101i and DNR-111i perform advanced, 10-bit, 3D Gaussian noise reduction and variable surface and edge filtering. In addition, the DNR-111i removes Mosquito noise, using Miranda’s proprietary region-based 3D-MONORD algorithm.
GUIDE TO INSTALLATION AND OPERATION 2 Installation 2.1 Unpacking Make sure the following items have been shipped with the DNR-101i or DNR-111i Digital Noise Reducer. If any of the following items are missing, contact your distributor or Miranda Technologies Inc. • • • DNR-101i or DNR-111i Digital Noise Reducer Rear panel labels This manual 2.
GUIDE TO INSTALLATION AND OPERATION 2.2.3 imaging Solo Frame To install this module into Solo follow these steps. For a closer look at module installation and removal, refer to the frame's Guide to Installation and Operation. 1. In order to remove the frame's front panel, gently pull on it. 2. Carefully place the DNR-101i/111i between the module guides and gently push the module towards the rear of the frame until the module's edge connector is secured to the backplane.

GUIDE TO INSTALLATION AND OPERATION 4:2:2: serial digital video input Connect a 4:2:2 serial digital video source to 4:2:2 IN. The DNR-101i/111i accept a 4:2:2 serial digital video signal in either 525 or 625-line format. This input must conform to the SMPTE 259M-C standard. Make sure the input 4:2:2 cable has a maximum length of 250 m (850'). An active loop-through is provided. Refer to section 3.3, Status Monitoring for a description of error and EDH status on the input signal.
GUIDE TO INSTALLATION AND OPERATION 3 Operation The DNR-101i/111i can be controlled in three different ways: • The card-edge push-buttons, 4-character display and status LEDs can be used to move through a menu of parameters and to adjust parameter values. • Miranda’s RCP-100 remote control panel can be used to access the same menu structure from a remote location.
GUIDE TO INSTALLATION AND OPERATION 1 2 3 Figure 3.1 DNR-101i/111i iControl graphic interface window The Config tab The Config tab includes basic functions of the DNR-101i/111i; refer to image 3.1 to locate the different elements. The Noise Filter Mode is available only with the DNR-111i. Select MNR to access the Block Artefact Remover in the Filter tab. MENU: MODE → MNR The Bypass checkbox allows the video signal to pass through without any noise reduction.
GUIDE TO INSTALLATION AND OPERATION To recall a saved configuration, select the register through the Select User box, then click Load User. The Filter Tab The Filter tab contains sliders for filters adjustments, and in the case of the DNR-111i, controls over the Block Artefact Remover. The best configuration is based on picture content, type of display device and perceived appreciation.
GUIDE TO INSTALLATION AND OPERATION increase residual noise from the 2D Spatial filtering and 3D Temporal filtering if they are not properly ajdusted. Use the slider to control the detail enhancer filter, ranging from 0 to 15. Default value is 0, which sets filtering to off. MENU: DE Noise Reducer - 2D Spatial Filter: This bidimensional, adaptive filter detects and reduces artefacts and mosquito noise in the picture caused by MPEG compression.
GUIDE TO INSTALLATION AND OPERATION The bottom portion, Error Sensitivity Selection, includes a checkbox for each of the status monitors, allowing it to be turned on or off. Click on ED & ID to select all except UES. Click Clear All to deselect all status monitors. At the bottom is an error counter, which counts up errors detected by the enabled aspects of the EDH (error detection and handling) system. The counter can be cleared, i.e. reset to zero. MENU: Not available through the menu system Figure 3.
GUIDE TO INSTALLATION AND OPERATION The Remote System Administration button at the bottom of the window opens a data entry box titled Joining Locators, in which the ADD option opens a dialog box in which the user can identify the Locator by its URL. MENU: Not available through the menu system Figure 3.6 The Info Tab 3.2 Remote Control Using the RCP-100 The menu structure of the DNR-101i/111i is also accessible through the use of Miranda’s RCP-100 remote control panel.
GUIDE TO INSTALLATION AND OPERATION 3.3 Card Edge Controls The front card edge consists of four pushbutton switches, six LEDs, and a four-character alphanumeric display. The LEDs indicate the status of various parameters as shown in the list below. The Alphanumeric display shows the input line standard during normal operation. It shows the current menu item when the card edge controls are being used to access the menus to change operating parameters.
