ATG Danmon Completes Major Systems Upgrades for Ericsson

ATG Danmon has completed a series of system expansion projects at the Stockholm headquarters of Ericsson Broadcast Services.

"These are the latest in an ongoing series of infrastructure enhancements and additions which have been completed successfully by ATG's engineers working in partnership with our technical management team," says Pontus Wahlstedt, System Engineer and Chief Designer at Ericsson AB. "They include upgrades of existing channels from standard-definition to high-definition plus additional technical facilities to accommodate new channels. ATG was the logical choice as its systems integration team has an in-depth understanding of the total studio, post-production and playout infrastructure at our Stockholm premises, going back to the building's origin as TV4 Sweden. A key element of each task was to ensure that all scheduled live-to-air and file-based transmission were able to continue without interruption."

"We have completed several projects for Ericsson in recent months," details Scott Adams, Senior Project Engineer at ATG Danmon. "These include a new studio for TV4 Sports News, new HD channels for Canal8 and TV12 and various upgrades from SD to HD.


"The TV4 Sports News studio project centred on additions to network-shared resources with new elements including optical camera feeds from the studio to the production switcher, an expanded Evertz multiviewer system, Cisco network switching and Axon glue.

"The new EBS Canal8 HD channel required integration of Miranda upconverters, an expanded Evertz multiviewer and Axon interfaces.

"Expanding Ericsson's infrastructure to accommodate the TV12 HD channel required installation, configuring and testing of a Miranda Imagestore 750 master control and branding processor. This has an integral flash-memory store capable of holding more than 4,000 high-definition or standard-definition images. We also integrated Miranda interfaces, Snell routing matrix expansion and Axon glue.

"The standard-definition to high-definition upgrade projects include TV4's K2 studio which centred on a further Snell router expansion. We have also added high-definition playout facilities for three Ericsson channels (Cmore, CMore Fotboll and CMore Hits) with another Snell router expansion, additional Miranda interfaces and Axon glue. In TV4's presentation studio we have integrated a high grade Sony OLED video monitor as well as TSL and Genelec audio monitors, camera fibre and Axon distribution amplifiers."


"Additional work recently completed at EBS in Stockholm has included expanded signal multiplexing resources, plus the large-scale installation of Harmonic Omneon ingest and playout servers for TV4."
