Advances in Wireless Video

THE EVENT: You will learn about the technical challenges of producing a live multi-city reality show. You will also learn about new wireless developments facilitating broadcast quality video with only a 7msec delay.

EXAMPLES DISCUSSED: 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 “live-from-the-street” police 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 gen-lock synchronization, and have perfect audio and video lip-sync, because there is no time in a live broadcast to correct synchronization issues.

In this presentation by Jim Jachetta, he will delve into the details behind the video transmission solution from VidOvation and AVIWEST solving this technical challenge.

You will 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 bit-rate encoding over bonded cellular and the public internet.

FEATURES PRESENTED:

  • Broadcast live from six or seven different cities simultaneously

  • Maintain Gen-lock, multi-camera synchronization and lip sync

  • Stream live at 130 MPH from a police vehicle

  • Stream live from handheld camera operators

No other technology was able to meet these challenges.
