Turner Taps Nvision for Master Control

Turner Broadcasting Systems Inc. has installed Nvision’s new NV5100MC multichannel master control switching systems for its major television services, which includes TNT HD, TBS HD, TBS east and west, Cartoon Network and Atlanta’s Peachtree TV.

Turner developed a master control model that could be replicated for its numerous channels. The requirements for the model included mirrored back-up capability under automation control, with the option to go to full manual-switcher operation as required; increased audio channels, including Dolby E processing capability for HD content with surround sound; integration of external graphics, along with insertion of closed captioning and other services, without disrupting program delivery; and due to limited space, compact master control switcher panels that fit Turner’s existing model for control room consoles.

“Nvision’s NV5100 master control met all our operational criteria and they worked with us to tailor their design to fit our space limitations,” said Bob Peck, senior project manager for broadcast technology and operations at TBS. “We also wanted to ensure our operators could preview events as they are being built, and without interfering with the automation.”

A unique feature to the NV5100MC is its independent full-function preview option. Features include all the video functions that will be in the final program event, including background, three external and two logo keyers, along with true dual-squeeze previewing if needed. Single or dual squeeze can be added as simple daughterboard plug-ins on the core program/preset processor as well as preview.
