GUIDE TO INSTALLATION AND OPERATION 2 Installation 2.1 Installation in the Densité frame The HCO-1822 and its associated rear connector rear panel must be mounted in a DENSITÉ frame. It is not necessary to switch off the frame’s power when installing or removing the card. See the DENSITÉ Frame manual for detailed instructions for installing cards and their associated rear panels. 2.
GUIDE TO INSTALLATION AND OPERATION The HCO-1822 provides two HD/SD SDI video outputs on BNC connectors, labeled PGM (program) and PVW (preview). The SDI video signals conform to the SMPTE 292M and SMPTE 259M-C standards. GPI IN and GPI OUT connectors The rear panel of the HCO-1822 includes a GPI interface that allows control of the switch process. When constructing and using an external GPI box, be aware of the following: 1. The HCO-1822 card monitors the external power supply voltage on the GPI input.
GUIDE TO INSTALLATION AND OPERATION 3 Operation 3.1 Control options The HCO-1822 can be controlled in different ways: • The local control panel and its push-buttons can be used to move through a menu of parameters and to adjust parameter values (see section 3.3). • Miranda’s iControl system can be used to access the card’s operating parameters from a remote computer, using a convenient graphical user interface (GUI). (see section 3.4) 3.
GUIDE TO INSTALLATION AND OPERATION 3.3 Local control using the Densité frame control panel 3.3.1 Overview Push the SELECT button on the HCO-1822 card edge (see Section 1.4) to assign the local control panel to operate the HCO-1822. Use the control panel buttons to navigate through the menu, as described below. All of the cards installed in a Densité frame are connected to the frame’s controller card, which handles all interaction between the cards and the outside world.
GUIDE TO INSTALLATION AND OPERATION 3.4 Remote control using iControl The operation of the HCO-1822 may be controlled using Miranda’s iControl system. • • This manual describes the control panels associated with the HCO-1822 and their use. Please consult the iControl User’s Guide for information about setting up and operating iControl. In iControl Navigator or iControl Websites, double-click on the HCO-1822 icon to open the control panel. 3.4.
GUIDE TO INSTALLATION AND OPERATION Icon 3 – Input 1 status • A: Green - Status OK; format shown • B: Red – Error Icon 4 – Input 2 status • A: Green - Status OK • B: Red - Error Icon 5 – Bypass Status • A: Bypass not active – switch operational • B: Bypass activated Icon 6 – Card Heath status • A: Green - Fan OK and GPI Power OK • B: Red - Fan error or GPI Power Error When an icon shows an error state, a message describing the error in more detail will appear beneath the icons.
GUIDE TO INSTALLATION AND OPERATION 1. Manual switch Manually switches the HCO-1822 output between the two possible sources: input 1 or input 2. • Click the Manual button. The two possible sources are shown on the left. The icon representing the currently-selected input will show in green. • Click on a different source. The selection shows blue, and the Take button is activated, appearing yellow.
GUIDE TO INSTALLATION AND OPERATION • NOTE: for certain errors, the switch-over is delayed by 0.5 second beyond the selected duration because it often happens that the same signal is feeding both inputs, possibly offset by a frame or two. The delay ensures that the alternate feed is indeed error-free before switching to it.
GUIDE TO INSTALLATION AND OPERATION 3.4.3 The Alarms panel The HCO-1822 continuously monitors the condition and status of the input signals it is processing. The information is used to decide whether the input must be switched in Auto mode. It is also used to flag the status of the card in the iControl system. In general: • A number of parameter values are continuously tested against user-defined thresholds or for presence/absence.
GUIDE TO INSTALLATION AND OPERATION Video – Video Error alarm This error is always ENABLED and the level set to 1, 2 or OFF. The factory default value is level 1. Use the slider to set the duration for which the error must continuously exist before the alarm is flagged. The nominal range of durations is 0.05 to 90 seconds. When durations ≥1 sec are selected, there is an additional 0.
GUIDE TO INSTALLATION AND OPERATION Video – Timing Error This error is generated if the timing offset between the output signal and the video input is greater than 2 lines. • This alarm is always enabled, but is not a switch condition for either of the inputs. The LED color is not configurable for this alarm. Figure 3.12 Timing Error alarm Config.
GUIDE TO INSTALLATION AND OPERATION Video – Freeze Detect This error detects the presence of a signal freeze (i.e. no change in content) for a period of time; the error is flagged only when the time duration criterion has been satisfied. This error can be Enabled using the checkbox, and the level set to 1, 2 or OFF.
GUIDE TO INSTALLATION AND OPERATION .Audio – Silence CH1 (same for CH2-16) This error flags the continuous absence of sound level in the specified audio channel for a specified duration. NB – this error applies only to PCM audio This error can be Enabled using the checkbox, and the level set to 1, 2 or OFF. The user sets the detection parameters for this error using two sliders: • Threshold (dB) – sets the signal level below which silence will be considered to have been detected.
GUIDE TO INSTALLATION AND OPERATION In1->In2 Click the checkbox to force all alarm parameters for input 2 to match those set for input 1. • When this is selected, only one set of alarm parameters is displayed for both inputs. • When the checkbox is deselected, the alarm parameters for input 2 revert to their previous values, i.e. as they were before the checkbox was selected. Figure 3.18 IN1 3.4.
GUIDE TO INSTALLATION AND OPERATION The graphic and the text at the top of the panel show the timing of the two inputs with respect to the reference. Input timing measurements are shown above (Input 1) and below (Input 2) the user-programmed output timing (shown in blue). If the measured input timing respects the supported input window, this measurement will remain green. If not, the measurement will turn red.
GUIDE TO INSTALLATION AND OPERATION 3.4.6 The Reference panel The HCO-1822 output signals should always be genlocked to some reference source. The genlock source is selected in the Reference control panel.
GUIDE TO INSTALLATION AND OPERATION 3.4.8 The Miranda ALC panel Minimizing loudness differences between segments in a playout channel is an important issue in a world where multiple programs originating in different formats from different sources must be integrated seamlessly. The Automatic Loudness Control (ALC) option is the solution to this need. It uses Miranda’s proprietary wideband ALC algorithm. • Identified as HCO-1822-OPT-ALC-X, where X can be 2, 6, 8 or 16 input channels.
GUIDE TO INSTALLATION AND OPERATION 3.4.8.2 PGM1-4 tabs Loudness monitoring When turned ON, the loudness meters display the program input loudness (before ALC processing), the dynamic correction applied by the ALC, the ALC limiter correction, and the program output loudness (after ALC processing). The input and output loudness are given in dBFS or LKFS, depending on the selected ALC filter (dB without filtering, LKFS for ITU-R BS.1770 filtering).
GUIDE TO INSTALLATION AND OPERATION Here’s the time-domain response of the ALC: ALC Pre-Amp Level A pre-amp stage is available in front of the ALC to compensate for programs having an input loudness out of the ALC tracking range (very low or very high input loudness). The pre-amp level ranges from -20 dB to + 20 dB, in steps of 1 dB. Fast Mode Response The Fast Mode Response is optional and is enabled by checking the Enable box.
GUIDE TO INSTALLATION AND OPERATION 3.4.9 The Fingerprint panel Fingerprinting technology on this card functions in conjunction with iControl. • iControl 4.0 and higher is required. HCO-1822 streaming is ON by default, but the management of the stream is handled in iControl, and there is no local control of the process at this card control panel, except to select the window, and to turn streaming OFF if there are problems with the stream or the network.
