Closed Captioning for IP Production:
Intuitive Workflows Have Arrived
T
he transition to IP workflows
is paying off
for broadcasters.
Evolving from hardware-driven SDI
workflows to software-controlled IP

reduce costs.
While the benefits of IP production
represent a clear choice, changing

often feel concerned that

it

Understanding the Move to IP
Demystifying captioning signal
paths for the IP paradigm is key to
achieving broadcasters' updated
benchmarks. Leveraging wellexecuted
software and cloud-based
content production help them meet
important goals, including:
* taking advantage of the
scalability, cost savings,
flexibility, and APIs in the cloud
* making remote production

The first is broadcasters who are
currently in the process of moving
away from the linear TV world and
traditional

into an IP-based model. Their new
IP workflow may be specifically
for their traditional
channel, or
it may be for a new non-linear

is how to migrate these activities
to a software/cloud/API-friendly
environment for all the advantages
they bring. As noted above, the
benefits

highly automated workflow requiring

remotely. Continuity
in

is key to this group, who place a
high priority on a familiar-feeling
experience within their new IPpowered
workflow.
For this user group, a solution such

engineering teams get access to the
latest technology without needing to
relearn their live captioning process.
