ATG Broadcast upgrades TV4 Sweden to HD

As the first stage in the transition to a full SD/HD parallel service, the broadcaster’s Omneon server was upgraded for HD ingest and an HD master control was added.

ATG Broadcast has completed an upgrade for one of Sweden's largest independent TV channels, TV4. The new installation includes HD ingest, upconversion and transmission facilities at TV4's headquarters in central Stockholm.

The HD ingest area includes a Snell & Wilcox Memphis MPEG-2 HD encoder and the addition of HD ports to TV4's Omneon server, plus a substantial investment in Axon interfaces and format converters. The upgrade added 2.7TB of disk storage to the Omneon archive, increasing the total online system capacity to nearly 11TB.

Channel branding will be provided by an Avid DekoCast graphics system incorporating clips and cell animation options. A new NVISION HD master control switcher will work alongside the existing Eyeheight SD switcher and will give the network's program controllers complete freedom to operate the SD and HD sister channels in tandem or with separate content. An existing 64-square Pro-Bel SD router has been expanded to accommodate 32-square HD crosspoints. The contract also included a 16-square HD router and Tektronix WFM7100 HD waveform monitor.
