Migrating Live Production to IP Technology
It’s About Time
![Page 3: MediaNet 2015 Chuck Meyer CTO – Production. Migrating Live Production to IP Technology It’s About Time](https://reader036.vdocument.in/reader036/viewer/2022062423/56649f3c5503460f94c5a7a1/html5/thumbnails/3.jpg)
Where we have been
Color television workflows embodied a brittle, camera-to-the-home stovepipe
Production was Directly attached to the home TV
Every business model ROI was based on 1 to many

Where we are Now
Digital television ( HD ) broke the strict connection between the camera and the home
Video production became line based
The requirement for nano-seconds is gone
Many new ROI models are proposed, leveraging IP technology

Bound the Problem
Time of Day – Only important to your PVR
Sampling time – Too fast to perceiveNanoseconds and Microseconds
Media Time – Sets the constraintVideo: mutual to a line ( ~15 usec )
Audio Image: mutual to a sample ( ~20 usec )
Lip Sync: audio to video ( -10 msec to + 30 msec )*

Strategy for Timing
• Source time cameras and mics• Data buffers exist at end-points
• Digital SDI works this way today• Today’s facilities are Time of Flight• IP can be managed this way as
well– And in the future PTP enables more

10 GbE Enables Live
Fabric delay with jitter is bounded: < ½ Video Line
Source timed, deterministic systems perform equally with today’s SDI
Time of flight design still works just like SDI
Upstream pre-select models stay the same
Familiar control surfaces still manage the facility

Multiple ROI models
Bandwidth scalability easily adapts to new formats
