Page 13: Applications
GUIDE TO INSTALLATION AND OPERATION 3 Applications 3.1 Downstream Branding In many cases, branding is done downstream of a Master Control switcher. In this scenario an LGK-3901 may be used for basic logo insertion (station logo, ratings, etc.). Moreover, advanced graphics can be achieved using an external graphics co-processor.
Page 14: Rich Graphics Keying - (Dsk-3901)
GUIDE TO INSTALLATION AND OPERATION 3.2 Rich Graphics Keying – (DSK-3901) This is a variant of the Downstream Branding application but without any basic logo insertion capability. A DSK-3901 card is supplied with rich graphical content from external graphics co-processor(s). Voice-overs may be supplied via embedded audio on one of the Fill inputs, or via external AES inputs.
Page 15: Downstream Parallel Branding
GUIDE TO INSTALLATION AND OPERATION 3.3 Downstream Parallel Branding This is a variant of the LGK-3901 Downstream Branding application, where one Master Control switcher feeds several branding devices in parallel. This scenario is usually seen when the same signal has to be branded differently, for different channels or different regions.
Page 16: Low-Cost Channel Branding For Specialty Channels
GUIDE TO INSTALLATION AND OPERATION 3.4 Low-Cost Channel Branding for Specialty Channels In the case of specialty channels, a Master Control switcher may not be needed as most content is played out directly from a server. There is no need to perform transitions from a server feed to a live feed and vice-versa. For this scenario, branding can be done on an LGK-3901 directly downstream of the server playout port, and for the low-end part of the specialty channels, a simple logo inserter may be ideal.
Page 17: Master Control Switching
GUIDE TO INSTALLATION AND OPERATION 3.5 Master Control Switching The LGK-3901 can be used as a traditional Master Control switcher, as it includes an optional AB mixer. In the case where live events need to be handled, the LGK-3901 is a compact and economic solution for stations which need a transition engine without all the features that typically burden the cost &...
Page 18: Master Control Backup
GUIDE TO INSTALLATION AND OPERATION 3.6 Master Control Backup In a traditional playout chain, a small utility router is typically used as a low-cost backup for the main master control path. Indeed, a small router is cheaper than a full Master Control switcher, and moreover, this configuration allows the backup path to bypass not only the Master Control switcher but also the main station router.

GUIDE TO INSTALLATION AND OPERATION • Loss of timecode • Loss of closed captions • Errors in embedded audio • Errors in Dolby E streams An SDI data analyzer is needed to monitor the timing of the SDI input sources and the outputs with respect to the facility reference.
Page 24 GUIDE TO INSTALLATION AND OPERATION To buffer half a line of 1080i / 59.94, increase the above reference timing to: 0 line +4.3µs (+15µs) = 0 line +19.3µs. Note: If the path delay of the SDI input sources is such that they are all offset from reference by several lines then adjust the reference by the same number of lines to align the output to the unusual input timing.
Page 25: Audio Processing
GUIDE TO INSTALLATION AND OPERATION 4.5 Audio Processing Audio processing requires the LGK-3901-OPT-AUD or DSK-3901-OPT-AUD audio option to be enabled. The audio engine provides the following possible features: • Input selection from embedded SDI or external AES • AB mixing of multi-channel audio sources for cuts and variable rate fades •...
Page 26: Example Route Manager Templates
GUIDE TO INSTALLATION AND OPERATION Some audio blocks are controlled by automation, and others may be set up to automatically follow other system states; for example audio AB mixing may follow video AB mixing and Easyplay clips may drive voice-overs and/or follow the up/down state of keying layers on Program or Preview.
Page 27: Easyplay
GUIDE TO INSTALLATION AND OPERATION The Duck value sets the amount by which the background audio level is attenuated when the voice-over is fully on. The Preset value sets the level of the voice-over audio when the voice-over is fully on. Both values are measured in decibels.
Page 28: Store Memory
The store memory is physically located as shown in the accompanying diagram. DSK-3901 may be upgraded to LGK-3901 by the addition of store memory and appropriate options, both purchasable from Miranda Technologies Inc (see section 9.2.3). Figure 4.3 Store Memory location Media files are always pre-loaded into the store memory prior to being keyed over background video.
Page 29: Keying Graphics
GUIDE TO INSTALLATION AND OPERATION 4.8 Keying Graphics Keying is the process of inserting one video signal (the Fill signal) into another video signal (the Background signal) according to a third signal (the Key signal). Graphics fill/key signals may be sourced from the following methods: •...
Page 30 Xplorer • Animation Builder (available from the MCS CD) • Miranda Adobe After Effects Plug-in (available from the MCS CD) 4.8.2.3 Easytext Easytext requires the LGK-3901-OPT-TXT option. CG text effects including static text and simple crawls are defined within OXA Easytext files, or templates. These templates may comprise of many text and/or image elements, all of which may be updated dynamically via automation.
Page 31: Emergency Alert System (Eas)
Air feature. This may be triggered from automation (see Oxtel Automation Protocol v15), GPI, control panel (such as the Miranda RCP-BR) or the front panel. When Emergency To Air is selected, the most downstream keyer that is associated with a store (on the program output channel) is faded down over 25 fields.
Page 32 • Since most receivers have analogue audio outputs, the audio will first need to be converted to AES using an external converter such as the Miranda ADC-1711 or ASD-771p. • The AES audio is then fed to the LGK-3901 via an external AES input pair and the audio is mixed onto the background via a voiceover.
Page 33 ‘Voiceover On’ and ‘Voiceover Off’ command and appropriate delays to ensure that the data for the crawl is received. Such GPI macros are outside the scope of this manual, but can be discussed with Miranda Support. As the LGK-3901 retains the last EAS text message received, the EASNone.oxa crawl will only be seen when the EAS mode is activated with no alert level.

Page 36 GUIDE TO INSTALLATION AND OPERATION Figure 4.4 Linear Keying Full keying is where the Fill signal needs to be multiplied by the Key signal prior to being added to the modified Background signal. In this case, the Fill has not already been cut by its key external to the LGK-3901/DSK-3901. The card cuts a hole in the Fill with the Key and then cuts a hole in the Background with a computed (1 - Key) signal.
Page 37 GUIDE TO INSTALLATION AND OPERATION 4.8.5.5 Masking The LGK-3901/DSK-3901 allows a rectangular masking area to be defined for each of the five keyers. This mask applies to any signals fed into the keyer; external fill/key signals, or the output from internal stores (LGK-3901 only). For internal images (LGK-3901 only), the area range of the mask is determined by the width and height of the image in pixels, and is limited by the selected video standard.
Page 38: Preview Channel
GUIDE TO INSTALLATION AND OPERATION 4.9 Preview Channel The LGK-3901/DSK-3901 Preview Channel is used typically for previewing graphics and audio voice-overs prior to bringing them to air on the Program Channel, but can also monitor a range of different video and audio signal paths throughout the video chain.
Page 39: Active Preview
4.9.3 Active Preview When LGK-3901/DSK-3901 is controlled via Miranda RCP-BR, Xpanel or iControl, keyers may be armed for cuts or fades. When enabled the Active Preview feature allows the keyers on the Preview chain to change state during an arm to show the keyer state that will occur on the next “Take” command. When disabled, the Preview keyers are controlled independently of the keyer arm state.

Page 42: Graphics Co-Processors
GUIDE TO INSTALLATION AND OPERATION 4.11 Graphics Co-Processors The LGK-3901/DSK-3901 can be configured for use with the following Miranda Graphics Co-Processors: • Miranda Imagestore Intuition+ Graphics Co-Processor • Miranda VertigoXG Graphics Processor (Single channel) The Co-Processor can generate complex output incorporating multiple objects (animations, clips, images and text) on numerous virtual keying layers.
Page 43 GUIDE TO INSTALLATION AND OPERATION For example, if an LGK-3901 receives a command to load a graphic into layer 0x5, it will forward this command onto the Co-Processor to load the graphic into the first keying layer. To do this the LGK-3901 subtracts 5 from the layer value before relaying the command.

Page 46: Closed Captions
GUIDE TO INSTALLATION AND OPERATION 4.12 Closed Captions Closed caption information is usually passed through the LGK-3901/DSK-3901 whatever the Closed Caption option is set to. The reason that the option exists is that when the standard is set as NTSC (525), closed caption information is found within the active picture (lines 20/21), and so it will be destroyed when graphics are keyed over these lines.
Page 47: Message Logging
This allows a remote syslog server to be set up, permitting log files to be logged externally. Setting up a syslog server is well documented on the Internet; however Miranda Support can also provide details. 4.14.3 Local Logging Local logging to the Compact Flash storage is enabled or disabled via the SETUP > LOGGING > LOCAL LOGGING front panel menu.
Page 48: System Configuration
GUIDE TO INSTALLATION AND OPERATION 4.15 System Configuration The front panel USER PRESETS menu is used to import and export different LGK-3901/DSK-3901 system configurations required for different user applications. For example a card may be switched between different video standards by creating two configurations and then importing the appropriate configuration file when a change is required.
Page 49: Exporting Configurations
GUIDE TO INSTALLATION AND OPERATION The active configuration from any LGK-3901/DSK-3901 card can be copied into the Configurator tool at any time so that granular edits can be made to the restart behaviour of volatile settings.
