Contemporary Research 12 QMOD-SDI 2

Installation - Sources

Process

 Connect source(s) to appropriate inputs

 Perform Quick Setup from front panel to test operation and channel

 Use USB Web pages or front panel menus to compete the setup

 The front panel LEDs will light if 2-channel or scaling options are enabled

SDI 1 and 2

 Source can be 1080p 60/59.94 Hz, 1080i 60/59.94 Hz, 720p 60/59.94 Hz, or 480i 29.97 Hz

 QMOD will sync to SDI resolution and display format on front panel display

 1080p 3G SDI will be formatted as 1080i (there is no 1080p format in QAM presently)

 If the resolution is not one of the above, the display will state “Incorrect SIG”

 If the QMOD can’t connect to the SDI feed, display will read “No Signal”. If there is a signal, the

connection can often be made using an SDI re-clocking device.

Video/CC

 The Video/CC input can be used to create an SD digital channel, or to feed Line 21 captioning data

Audio Inputs

 SDI audio can be assigned to four groups of embedded audio, Dolby audio is passed through, stereo

AES is processed as Dolby Digital stereo in the program

 The SPDIF Coax and analog Stereo inputs can be assigned to any input

 When using 2 language tracks, the first will be Dolby Digital, the second MPEG1 Layer 2 stereo

Ethernet

 The IP and Telnet ports are assigned via front panel or Web menus

 Streaming options can be set locally or remotely

EAS

 EAS (Emergency Alert System) operation is triggered by a latching input on the SW and Ground pins, a

5-12 VDC level on the V+ and Ground pins

 The assigned EAS inputs, usually Video and Stereo, will broadcast on both programs when active

Multicast

Multicasting streams require a router with Multicast capability – the router creates the copies needed for user

requests. Use IP addresses 224.0.0.1 through 239.255.255.255, which are set aside for multicast streams.
