Sweden’s Teracom is using Thomson Video Networks‘ ViBE VS7000 video system, NetProcessor 9030/40 multiplexer and Sapphire MPEG stream server for 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 enabled by the ViBE VS7000 and the DVB-T2 gateway processing provided by the NetProcessor multiplexer.
Teracom’s end-to-end Ultra HD delivery process begins with the ViBE VS7000, an “anything in, anything out” encoding/transcoding platform. The ViBE VS7000’s file transcoding capabilities enable output of Ultra HD/4K resolution, using either H.264 or HEVC encoding.
Sapphire is used to broadcast this Ultra HD content. The Sapphire MPEG stream server provides all the functions necessary to acquire, process, brand and generate TV channels. The Sapphire output is fed to the NetProcessor, which in turn encapsulates the multiplex into a DVB-T2-MI stream, providing signalization, transmission and synchronization parameters to DVB-T2 modulators.
By embedding the DVB-T2 gateway and inverse DVB-T2 gateway, the NetProcessor system improves the overall transmission architecture while reducing equipment and potential points of failure.
