SEATAC, WASH.—Advanced Broadcast Solutions announced it designed and installed a new
HD-SDI infrastructure with embedded audio for KHSL-TV, the CBS affiliate
serving the Chico-Redding, Calif., market (DMA No. 132). The native HD upgrade
included new master control and production control rooms, plus new studio and
ENG cameras, NLE systems, and the adoption of a tapeless workflow.
Owned by GOCOM Media of Northern California, KHSL shares operations with KNVN,
the local NBC affiliate owned by K4 Media, as part of a joint facility
arrangement. Aaron “Mike” Roberts, director of engineering, said the ABS
project provided a technological fresh start for the facility, which had
previously transitioned from analog to digital SD, then to an HD/SD hybrid
infrastructure. The facility had layers of cables that could not be organized
or removed until after the new infrastructure was operational.
ABS completed the project in November 2013, and the facility began using its
native HD system in January. The new HD-SDI infrastructure includes embedded
audio, which significantly reduced cable runs. In fact, more than four racks of
system routing equipment were replaced by a 4 RU 128x128 Utah Scientific
router. Other master control upgrades include Harmonic Omneon video servers
controlled through NVerizon automation.
Built around a Ross Carbonite production switcher, the new production control
room features a Miranda Kaleido multi-viewer, Panasonic LCD monitors, Ross
XPression CG, BlackStorm playout server, Yamaha LS9 audio board, Clear-Com
intercom system and custom furniture from Martin & Ziegler. All newsroom
edit systems were also upgraded to Adobe Premiere CS6 and are connected to an
18 TB SAN system.
For field production, ABS replaced an aging group of tape-based camcorders with
eight JVC GY-HM600 ProHD handheld camcorders with built-in 23x Fujinon lenses.
Part of KHSL’s new tapeless workflow, the cameras record HD footage to SDHC or
SXHC media cards. Roberts said the new cameras were particularly effective
shooting low-light footage, which was beneficial at the site of a local April
10 accident between a FedEx truck and school bus that gained national
Rather than traditional studio cameras, ABS installed five Panasonic AW-HE120
robotic PTZ HD cameras, each with a custom 13-inch LCD prompter system mounted
on top that maintains the eye line of the news anchors.
During the project, ABS personnel utilized a vacant space on the second floor
of the facility to relocate the analog news production. The space formally used
by news production was then used to assemble new racks and equipment. Once the
HD infrastructure was in place, ABS created the new master control for KHSL and
KNVN, and its three multicast channels.
The facility’s original location for master control was designed to support a
single station, so master control had been moved several years ago during an
upgrade to accommodate multiple channels. However, technological innovations
allowed ABS to return master control back in its original location. The new HD
news production equipment was then installed in the space previously occupied
by master control.
