Zurich, Switzerland (October 26, 2010)–More than 1000 Barix Audio over IP devices were used for contribution, distribution and monitoring of live broadcast audio for the recent 2010 Commonwealth Games in Delhi, India.
The 2010 Commonwealth Games, held from October 3-14, were reportedly the largest multi-sport event staged in India. More than 6,000 athletes from 71 Commonwealth nations and dependencies competed in 21 disciplines. Host public broadcaster Prasat Bharathi produced the official “International Signal” live from 12 competition venues.
Prasat Bharathi contracted Mahanahar Telephone Nigam Limited (MTNL), a telecom service provider and provider of broadband services in Delhi, to install and operate a redundant fiber network from all 12 venues to the International Broadcast Center (IBC), transporting IP audio over MPLS. The IBC managed and delivered more than 40 contribution and 250 coordination feeds to and from the venues, and served as the origination point for broadcast signals delivered globally to rights holders.
Barix Exstreamer 1000 professional IP encoding/decoding devices were the core audio transport solutions, with special firmware from Barix to deliver very low-latency audio (between 20-30 milliseconds of delay). Redundant pairs of Exstreamer 1000 devices contributed live sports commentary and broadcast-quality event audio from each venue to the IBC. Any broadcast facilities receiving live feeds from the IBC used Barix Exstreamer devices to receive and decode the program audio.
MTNL, using Barix IP audio and CISCO network components, established an IP network that exceeded the performance levels of traditional telephone links, and met the signal quality requirements of all broadcast partners. Barix IP devices additionally provided SNMP traps that allowed personnel to monitor the links from the MTNL network center at the company’s operational headquarters.
