Sweden's Teracom is using Thomson Video Networks’ ViBE VS7000 video system, NetProcessor 9030/40 multiplexer, and Sapphire MPEG stream server to demonstrate a complete transmission chain for DVB-T2 delivery of HEVC-encoded video.
To enable delivery of Ultra HD content, Teracom has combined its DVB-T2 transmission capability with the HEVC compression efficiency enabled by the ViBE VS7000 and the DVB-T2 gateway processing provided by the NetProcessor multiplexer.
Teracom's delivery model begins with Thomson Video Networks' ViBE VS7000, an encoding/transcoding platform powered by Thomson's MediaFlex video operating system. The ViBE VS7000's file transcoding capabilities enable output of UHD/4K resolution, using either H.264 or HEVC encoding. Thomson Video Networks' Sapphire is then used to broadcast this UHD content.
Teracom is feeding the Sapphire output to the NetProcessor, which encapsulates the multiplex into a DVB-T2-MI stream, providing signalisation, transmission, and synchronisation parameters to DVB-T2 modulators.
"By deploying state-of-the-art technology on our infrastructure to enable DVB-T2 transmission of HEVC-encoded Ultra HD content, we are demonstrating that we are capable of offering our customers the highest quality viewing experience," said Håkan Axén, product manager at Teracom Group. "Thomson Video Networks products enable us to leverage HEVC to realise compression efficiencies of up to 50%, which in turn makes it possible to broadcast Ultra HD services to the home."
