Simplifying Video Transport
SDI/SDTI 4 Channel Analog/Digital AES Audio Embedded
and Optical Transmitter [DLC150E]
DigiLink Video Transport System
FEATURES
Single card audio embedder and video transport
Embed into SDI or SDTI
• One-to-four analog audio
channels
• One or two AES-3 audio pairs
• Asynchronous or synchronous digital audio
• Standby video signal continues to deliver audio
on loss of video input
Optical transport (with or without embedded audio)
• SD-SDI (SMPTE 259M-C, ITU 656)
• SDTI (SMPTE 305M)
• DVB-ASI
• Analog Audio (4)
• AES-3 (2 stereo pairs)
• Full reclocking removes jitter from SDI
Externally accessible SFP transceiver optics
• Optical budget to 33dB
• WDM (1310nm, 1550nm)
• CWDM ITU G.694.2 (Channels 27-61)
Inputs
• Video (with or without embedded audio)
• 75ohm BNC
• Other modules on DigiLink chassis
(via backplane)
• Audio

The DLC150E is a flexible audio embedder and video transport card
designed for use in the DigiLink video transport system. The DLC150E
will embed analog or AES audio into SDI and SDTI as well as transport all
standard 270Mb/s digita l formats.
The DLC150 functions as both an audio embedder for four channel analog or two stereo
pair AES-3 audio, and as a 270Mb/s video over fiber optics transport module. The DLC150
uses industry standard 1310nm, 1550nm, and CWDM Small Form-Factor Pluggable (SFP)
optics. Provisioning and monitoring is accomplished using switches, LEDs, front monitor
jack, SNMP or HTTP via DigiLink Manager.
