Clear Channel Advertising Agency Streams High-Quality Digital Signage at Low Bitrates to Subway Stations With Matrox Maevex H.264 Encoders & Decoders
Clear Channel Norway installed Matrox Maevex™ H.264 encoders and decoders to deliver advertising content on 176 digital screens in 3 stations within the Oslo metro system. The distributed digital signage is no longer impacted by metro-run system tests that abruptly shut off the power. Consequently, screens, along with Matrox AV-over-IP devices, are now controlled remotely via Matrox Maevex PowerStream™ software.
Composed of 6 lines and 100 stations, the Oslo metro system features an annual ridership of over 80 million. While considered prime advertising real estate, the metro system presented several challenges for integrator Clear Channel Norway to deliver digital signage in three metro stations.
