Advances in Wireless Video

The technical director of A&E's live reality show "Live PD" faced several technical issues.  One major challenge was how to cost-effectively produce a lie cop show in six cities simultaneously using up to 41 cameras.  The show is a REMI (Remote Integration Model) production, where every camera is home run from each police vehicle to A&E master control in New York.  All cameras must be in perfect genlock synchronization, and have perfect audio and video lip-sync, because ther is no time in a live broadcast to correct synchronization issues.

In this presentation we'll dive into details behind the video transmission solution from VidOvation and AVIWEST that solved this unique technical challenge.  Learn about AVIWEST's SafeStreams technology, with advanced forward error correction, that automatically re-requests dropped packets and uses bonding techniques, precise timing, and adaptive bitrate encoding over bonded cellular and the public internet.

Time permitting, we will also discuss new developments in wireless technology that facilitate broadcast-quality transmission up to 3 kilometers with only 7 milliseconds of latency.  A unique combination of adaptive modulation and a highly adaptive H.264 codec enable reduced latency and increased picture quality in wireless video transmission.



In an effort to better predict turnout we are now using Eventbrite for monthly meetings.  If you expect to attend please register.  There is no obligation, and unregistered walk-ins are still welcome, but this will help us gauge room size and refreshment orders in advance.


The NAB building is at the junction of N Street, 18th Street and Connecticut Avenue, just south of DuPont Circle.  There is street parking on many blocks in the vicinity - check signs and meters for hours!  The closest Metro stops are DuPont Circle (Red line - two blocks) and Farragut West (Orange/Blue lines - four blocks)
