Video Delay
User selectable 0 ... 15 frames, can be disabled
Audio
24-bit, transparent forwarding of PCM and compressed audio
Sample rate = 48kHz (SDI compliant)
Channels = 16 inputs and 16 outputs (4 groups of 4 channels each)
Delay = Embedder audio delay selectable 0 ... 320ms per channel
Metadata (RDD6)
1 channel input, 1 channel output, SDID selectable
BNC Input
Impedance = 75Ohm
Return loss = >15dB 5 ... 1485MHz; >10dB 1485 ... 2970MHz
Maximum cable length = 250m (SD), 230m (HD), 140m (3G) using Belden 1694A cable
Jitter tolerance = >0.7UI (alignment)
BNC Output
Impedance = 75Ohm
Output voltage = 0.8Vpp (typical)
Return loss = >15dB 5 ... 1485MHz; >10dB 1485 - 2970MHz
Output jitter = <0.2UI (alignment), <0.5UI (timing)
Latency
Video latency input to output = 120 ... 200 pixel, depending on video standard
Audio latency input to output, embedder and de-embedder combined = <0.6ms (HD, 3G), <2ms (SD)
General Features
Power fail relay bypass (may be enabled/disabled via GUI)
Lip-sync compensation for processed and non-processed audio signals via video delay
Dedicated routing for non-processed channels; all channels (maximum 16) can be routed to/from the device or looped through
Test pattern generator (no genlock)
Master-sync capable
ITU-R BT.1685 / ARIB STD-B39 metadata support
