broadcastreport WORLD A dual format w rld


Commentary is a major part of sports broadcasting. In some technological respects it has changed very little but in others it has changed a great deal. Kevin Hiltonreports


IN TV AND radio commentary analogue has not been pushed to the sidelines by digital, unlike other areas of broadcast audio. The two formats have settled into a co-existence, giving operators the choice of what suits their needs. This is true for the three sub-


divisions of commentary systems: ISDN, POTS/PSTN (plain old telephone service/public switched telephone network) or IP codecs for single reporter use; stand- alone units with more features but which are still run by the commentary team; and larger, more sophisticated systems controlled by an engineer. Marc Wilson, sales and


marketing manager at Glensound, acknowledges that IP is now “the most popular codec option” but says the company is “disillusioned” with the technology due to the lack of “robust, simple standards”. He adds: “Where ISDN is available it is still the reliable choice.” While not embracing IP, Glensound has adopted HD Voice (see page 40), the wideband internet telephony standard, and offers a reporter’s mobile phone based on this. It has produced the RECCE HD, a three-channel mobile phone and commentary unit that works on 3G HD Voice networks. At its most basic the standalone commentary system has inputs for two microphones and outputs for two headphones, one each for the commentator and the ‘pundit’. In recent years this configuration has been expanded to offer positions for two or three commentators and one guest. Sonifex has recently moved into the standalone commentary system market with its CM- CU21, an analogue desk with two commentator positions and one for a pundit, while CTP Systems offers the DC2012. CTP established itself in commentary with the DC99-II, which was succeeded by the two-position DC2012, which is analogue but digitally controlled. CTP managing director Chris Thorpe observes that OB


companies want something “that will work wherever”. In a strange quirk of the industry, Thorpe says there was some initial resistance to the DCS2012 because it has digital control and a LCD display: “People are happy with digital routers for OBs but they were more concerned about LCDs on a commentary unit.” An analogue single commentator/voice-over booth unit is set to appear from CTP this year. Fully digital commentary systems were greeted with suspicion when they first began to come on the market around 12 years ago. Spanish manufacturer AEQ led the field with the DCS-10, which became the preferred commentators’ system for the Olympic Games. AEQ’s director of


international sales, Gustavo Robles, says: “At larger events, the digital domain is becoming more and more important,” he says. “Complexity and what is demanded from the overall system solution is having greater importance than 10 years ago. This is where digital becomes advantageous.” Klotz entered this niche


market in 2003 with the Voice but later withdrew it due to lack of demand. Glensound joined the fray in 2008 with its GDC-6432, which can run on coax, copper or fibre Ethernet. Big events such as the Olympic and Commonwealth Games are now more likely to feature digital commentary systems due to the need for central control and scalability. “Digital enables us to increase or decrease the number of commentary systems offered to the client broadcasters without redesigning the system,” explains Andy James at SIS LIVE. Riedel now produces the CCP-1116 commentary unit to work alongside its intercom systems, while Delec takes a similar approach with the oratis commentary and talkback range. Last year Finnish public


broadcaster YLE started to move from ISDN to IP and introduced digital commentary systems, with


Riedel DSC-16 panels with modified mic preamps or CCP-1116 commentary units connected to the manufacturer's intercom system. While all this goes on in the


background, there is still doubt whether integrated thinking goes on for the commentators and pundits that use the equipment.
