Satellite Broadcasters to Offer Best-Quality Transmissions at Olympics
By Carolyn J Dawson, TMCnet Contributor
The use of Carrier ID during satellite transmissions of the London 2012 Olympic Games was announced at IBC in September 2011. Work is in full swing for the deployment of Carrier ID by satellite broadcasters, thereby ensuring the best quality of satellite TV services across the globe. The London Olympics is being termed as one of the most-watched events, with an anticipated generation of at least 2,000 hours of satellite coverage.
Satellite operators will be able to recognize transmissions to their satellites in a more competent manner with Carrier ID, which is essentially a mark on uplink signals. When signal interference occurs, Carrier ID helps satellite operators speed up coordination with earth station operators.
The majority of the satellite community, comprising of satellite operators, encoder and modulator manufacturers, broadcasters and uplink providers, are busy ensuring that the DVB satellite being transmitted are of the best quality. Three worldwide associations, namely the World Broadcasting Unions-International Satellite Operations Group, the Global VSAT Forum (News - Alert) and sIRG or satellite Interference Reduction Group are also assisting this effort.
In a joint release, David Bair, CTO of Eutelsat; Thierry Guillemin, CTO of Intelsat; and Stewart Sanders, SVP, Customer Service Delivery at SES (News - Alert) said, "This is the first phase of a long-term collaborative undertaking to implement Carrier ID in order to further raise the bar of quality to our broadcast customers. It underscores our constant quest to improve technologies and procedures to deliver the highest standards of service."
Major satellite operators like Eutelsat, Intelsat (News - Alert) and SES, whose collective orbital assets equal to nearly 60 percent of global commercial satellite capacity, have already incorporated Carrier ID information into their earth station information tables, thereby guaranteeing the understanding, extraction and analysis of Carried ID data.
Martin Coleman, executive director of the Satellite Interference Reduction Group; David Hartshorn, secretary general of the Global VSAT Forum; and Dick Tauber, chairman of WBU-ISOG and VP Transmission Systems and New Technology (News - Alert) at the CNN News Group said, "The satellite communications and broadcasting industries are to be commended for this breakthrough. Never before have had broadcasters, satellite operators, uplinkers, and manufacturers collaborated to implement an initiative with the sole objective of improving the quality of satellite television services for millions of viewers."
