CBC Sports Utilizes i-Mix G3 as Digital Audio Mixer For World Figure Skating Championships Coverage
- i-Mix G3 with Cross-Point Digital Matrix Router/Profile Editor Allows Canada's National Public Broadcaster Custom Audio Routing and Profile Management -
Tokyo - (Mar. 25, 2007) - When the 2007 World Figure Skating Championships conclude here today new champions will have been crowned and Canadians may finally get some sleep. The cause of the sleeplessness has been CBC Sports' unprecedented six days of coverage of the event that included live broadcast back to Canada in the wee hours of the morning in addition to nightly primetime programming.
Tieline Technology, a leading provider of high-quality remote broadcast digital audio codecs, is pleased that as part of the extensive coverage, CBC Sports has relied upon the i-Mix G3 as a full communications and on-air talent mixer.
"We needed a comprehensive, flexible box," said Anthony DuBoyce, CBC Technology's Senior Manager for Advanced Systems Development & Integration. "The key is that we can talk to the host on one line and talk to all the talent on the other line."
While Tieline's i-Mix G3 is normally recognized for its codec capabilities, CBC/Radio-Canada is using the i-Mix as a digital mixer with IP remote control capabilities and with an embedded Matrix Cross-Point audio router for specific commentary and mixing needs.
CBC Sports set up a production "cabin" within 1,000 feet of the venue and ran multiconductor, 50-pair audio cable from its commentator positions back to the mixer. DuBoyce said the i-Mix Matrix was set to run two 4-wire circuits as intercom into the box, two each for host and color commentators. The left and right channels brought program sound and mic signals on one side and two intercom feeds on the other channel.
The i-Mix also handles the remote control of the gain/mic level. CBC Sports used another technology to put IP over duplex twisted pair.
"Remote control of the level of the color commentary is one way we use it. Levels can be different during the event and it is difficult for us to interrupt them on air.
Two i-Mix G3's made the trip to Tokyo, one as a fail-safe. The boxes came with POTS or ISDN module but the codecs weren't used this week.
The Tieline i-Mix G3 is part of a shrinking on-site production aspect of the CBC Sports international events coverage. 95 percent of the production is done back in Toronto. On-site handles primarily the premix and also gain controls.
CBC Sports has undertaken in the last few years a bold, innovated approach to the coverage of live events with a new remote control production model designed to significantly reduce production costs. Starting with the 2004 Summer Olympics in Athens, Greece, CBC/Radio-Canada deployed high speed networks and the latest technologies in compression and video serving to transmit raw feeds to its studios in Montreal and Toronto for local editing and broadcast.
CBC/Radio-Canada is Canada's national public broadcaster and one of its largest cultural institutions. With 28 services offered on Radio, Television, the internet, satellite radio, digital audio, as well as through its record and music distribution service and wireless WAP and SMS messaging services, CBC/Radio-Canada is available how, where, and when Canadians want.
Through this array of activities, CBC/Radio-Canada brings diverse regional and cultural perspectives into the daily lives of Canadians in English, French and eight aboriginal languages, in nine languages on its international Radio service, RCI, and in eight languages on its web-based radio service RCI viva, a service for recent and aspiring immigrants to Canada.
