1 SCO-1421 Intelligent ASI Change-Over with Probing

1.1 Introduction

The SCO-1421 is a 2x1 intelligent ASI change-over with built-in MPEG-TS probing. Changeovers are performed

electronically by the SCO-1421’s internal router. In the event of a power failure, the signal is protected by relays fitted

on the rear module, maintaining the integrity of the selected signal at the output.

Input selection can be performed automatically or manually. In automatic mode, the card will perform smart input

selection based on rules related to signal quality. In manual input selection mode, channel selection can be made

from the Densité controller, the iControl software, or simply by using a GPI. A GPI can be connected to an automation

system or any simple GPI control panel. The GPI outputs give status of the selected source, allowing tallies to be

triggered.

The card comes with sync-loss-free switching that prevents sync loss or sync drop errors upon switching.

MPEG-TS signal probing monitors PID presence of up to 12 services per input simultaneously.In the event of a loss

of data on any service PID, the SCO can be configured to automatically switch to the other input provided it is error-

free.

The optional advanced probing option enables full level 1 & 2 TR 101 290 probing and alarming. Combined with the

optional advanced probing, the SCO-1421 is not only the perfect ASI change-over but also a handy TS probe.

1.2 Features

•Two DVB-ASI source inputs and two DVB-ASI outputs (program and preview)

•Electronic switching with relay back up (on rear module) maintains selected input in the event of a power failure

•Automatic switch mode ruled by internal TS probes

•Manual changeover by local frame controller, iControl, iControl Solo or GPI

•GPI in for control & out for status monitoring (IN1, IN2, AUTO, BYPASS)

•Switching without TS sync loss errors

•Alarm reporting to iControl monitoring and control system

MPEG-TS signal Analysis

2.1 Unpacking

Make sure the following items have been shipped with your SCO-1421. If any of the following items are missing,

contact your distributor or Miranda Technologies Inc.

•SCO-1421 Intelligent ASI Change Over with Probing

•SCO-1421-DRP-R Rear Panel (see figure 2.1)

2.2 Installation in the Densité frame

The SCO-1421 and its associated rear connector 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.

2.3 Rear Panel Connectors

The SCO-1421 has multiple inputs and outputs, and making space for all the necessary connectors at the rear of the

frame requires a double-width rear panel.

With the double-width rear panel installed, the SCO-1421 must be installed in the right-most of the two slots covered

by the panel in order to mate with the panel’s connectors.

If it is placed in the wrong slot, the front panel LED will flash red. Move the card to other slot for correct operation. No

damage will result to the card should this occur.

The rear panel connections are as follows:

ASI IN 1 and ASI IN 2– serial digital ASI input

Connect two DVB-ASl video signals, conforming to EN 50083-9, to the BNCs labeled ASI IN 1 and 2.

ASI OUT – serial digital video outputs

The SCO-1421 provides two ASI video outputs on BNC connectors, labeled PGM (program) and PVW (preview). The

ASI video signals conform to EN 50083-9.

GPI IN and GPI OUT connectors

The rear panel of the SCO-1421 includes a GPI interface that allows control of the switch process.

Figure 2.1SCO-1421-DRP-R Rear Panel

GUIDE TO INSTALLATION AND OPERATION

4| SCO-1421

When constructing and using an external GPI box, be aware of the following:

1. The SCO-1421 card monitors the external power supply voltage on the GPI input. If the voltage is less than 4V

(per relay datasheet), an alarm will be raised.

2. When a GPI INPUT is triggered while the card is operating in auto mode, the card changes to manual mode and

switches to the input selected by the GPI.

3. DO NOT TRIGGER BOTH GPI INPUTS AT THE SAME TIME OR ALLOW THE TRIGGER PULSES TO

OVERLAP, AS DAMAGE TO THE RELAY MAY RESULT.

4. A GPI trigger pulse should have a duration of at least 40 ms.

Figure 2.2 GPI trigger pulse timing

Using the GPI interface

•Trigger the GPI-IN-1 or GPI-IN-2 pin to select that input.

•Trigger the AUTO-IN or BYPASS-IN pin to select that mode

•Read the GPI-OUT-1 and GPI-OUT-2 pins to identify which

output is selected

•Read the AUTO-OUT and BYPASS-OUT pins to determine

whether either of these modes is in operation.

The four GPI connectors are laid out as shown:

3 Operation

3.1 Getting Started

- The switch mode is set to AUTO by default which means the card will automatically switch to the input with

the less errors based on the error configuration that has to be done in the ALARM tab. Don’t forget to change

this setting if you don’t want the card to switch by itself.

- When in AUTO mode, the switch conditions must be set by the user as desired as most of them are set to

OFF by default. The LEVEL parameter of the measures that should cause a switch when error occurs must

be set to 1 or 2 according to the priority (1 being the most critical) or the card will never switch by itself.

- If the preview output of the card is connected, do not forget to set it’s behavior as desired on the preview

output tab.

- As it is NOT possible to probe every program present in the stream, many of the TR 101 290 measures are

only done on the programs selected for probing. It is very important to select the programs that you wish to

probe (up to 12) under the “Service Presence X” item in the ALARM – TS tab. Without doing so, many

measures indicators will always be green and won’t work as expected. The Pie Chart and PID Presence

display reporting depend also on this Service Presence setting.

- Once configured and fed with a valid signal, it is a good idea to reset the error count under the PROBING -

TR101290 tab if you want to clear the errors that might have occurred during configuration.

3.2 Control options

The SCO-1421 can be controlled in two 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 3.4).

•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 3.5)

3.3 Card-Edge Status LED

The status monitor LED is located on the front card-edge of the SCO-1421, and is visible through the front access

door of the DENSITÉ frame. This multi-color LED indicates the status of the SCO-1421 by color, and by

flashing/steady illumination.

The chart shows how the various error conditions that can be flagged on the SCO-1421 affect the LED status.

•If a cell is gray, the error condition cannot cause the LED to assume that status

•If more than one LED status is possible for a particular error condition, the status is configurable.

See Section 3.5.8 for details.

•The factory default status is shown by a 

The LED will always show the most severe detected error status that it is configured to display, and in the chart error

severity increases from left to right, with green representing no error/disabled, and flashing red the most severe error.

If the LED is Flashing Yellow, it means that the card is selected for local control using the Densité frame’s control

panel. See Section 3.4 for details.

3.4 Local control using the Densité frame control panel

3.4.1 Overview

Push the SELECT button on the SCO-1421 card edge (see Section 1.4) to assign the local control panel to operate

the SCO-1421. 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. There are no operating controls located on the cards themselves. The

controller supports remote operation via its Ethernet ports, and local operation using its integrated control panel.

The local control panel is fastened to the front of the

CPU-ETH2 controller card, and when installed can be

accessed by opening the front door of the frame. The

panel consists of a display unit capable of displaying

two lines of text, each 16 characters in length, and five

pushbuttons.

The panel is assigned to operate any card in the frame

by pushing the SELECT button on the front edge of that

card.

•Pushing the CONTROLLER button on the control

panel selects the Controller card itself.

•The STATUS LED on the selected card flashes
