Using SDI Sync Out
SDI Sync Out port is a re-clocked loop-through port of SDI Sync In. You can use this re-clocked reference
for additional Pipelines or other devices.
RS-422. Female DB-9 RS-422 port for VTR, using Sony 9 Pin Protocol (one per channel).
SDI In. BNC jack for SDI input (one per channel).
SDI Out. BNC jack for SDI output (one per channel).
Gigabit Ethernet Port. The Ethernet RJ-45 jack has two LEDs: If the left, orange LED is lit and the right,
green LED is lit, the port is operating at 1Gbs (gigabit). If only the orange LED is lit, the Ethernet port is not
connected. Be sure to use CAT-6 cabling end-to-end from Pipeline to your Macintosh or Windows PC
client for best results.
PIPELINE HD DUAL HARDWARE
The Pipeline HD Dual is 17.3 inches (43.9 cm) wide, 13.2 inches (33.5 cm) deep, and 1.5 inches (3.8 cm)
high. Pipeline HD Dual is a single rack unit, with two onboard HD/SD-SDI encoder/decoder devices
equipped with two external Gigabit Ethernet ports, using TCP/IP, UDP, RTSP, and RTP and Bonjour for
service discovery. Serial Digital Interfaces are provided for each device (BNC, SMPTE-259M 270mb/sec)
with two 8-channel embedded audio input and output ports with automatic input format detection, and RS-
422 deck control ports, using Sony 9-Pin Protocol.
Pipeline HD Dual can encode and decode DV/DVCPRO 25/50, IMX 30, 40, 50, MPEG-2 50M I-frame,
Apple ProRes SD/HD, Avid DNxHD and DVCProHD video, and 48 kHZ, 16/24 bit, uncompressed audio.
Using SDI Sync Input
The SDI Sync Input is used in both capture and playout modes but for two different purposes.
In capture mode, the SDI Sync Input is used as a method for supplying a common timecode reference to
all input channels. For the timecode to be extracted, the SDI signal connected to the SDI Sync Input must
contain a valid timecode in the vertical blanking area of the signal. This timecode is usually referred to as
VITC (vertical interval timecode). The SDI signal must be a digital signal that is frame synchronized with
the SDI signals used as the input video source for the timecode extraction to work properly. An analog
signal cannot be connected to the SDI Sync input.
In playout mode, the SDI Sync Input is used as a frame synchronization source for each of the SDI
outputs. Any timecode on the SDI Sync Input is ignored in this mode. If no signal is connected to the SDI
Sync Input, each of the SDI outputs will free run (i.e. they will not be synchronized with each other or with
any house reference). An analog signal cannot be connected to the SDI Sync input.
Caution
If only the green LED is lit or the LED is unlit, the Pipeline is operating at 100 or
10 Mb respectively. These data rates are unacceptable for real time video traffic
from all four channels. Resolve the problem by connecting at 1 Gbs before
processing jobs to avoid data loss.
