CBS Newspath uses Scopus DVB transmission gear
CBS Newspath deployed Scopus Network Technologies’ DVB digital video transmission equipment to cover both the Democrat and Republican National Conventions this summer. Using a Scopus Codico platform for encoding video signals, CBS Newspath delivered up to 15 different channels for CBS affiliates to pick up live remote feeds from the convention sites.
CBS Newspath provided workspace and transmission facilities for affiliates and international broadcasters who wanted live on-site convention coverage.
For the Republican convention at Madison Square Garden in New York, eight VBR channels were statistically multiplexed into an MCPC stream with Scopus E-1000 encoders, under the control of a Scopus NMS-4000 management system, and routed into two RTM Series multiplexers. Additional RTM-3310 multiplexers aggregated four CBR ASI stream channels along with this eight-channel MCPC stream to produce the final 12-channel MCPC uplink package.
The output of those devices passed through a SDM 2020 modulator, hit a Codico RSW-7200 redundant switch, was output to an Advent uplink system for transmission to IA6 (formerly Telstar 6) Transponder 3 as a 47.25Mb/s MCPC carrier, and then downlinked by various affiliates across the country. This system and its associated efficiency allows CBS Newspath to transmit 12 channels in less than a full transponder, allowing other CBS groups to use the remaining transponder bandwidth.
Compared to the configuration used for the DNC at the RNC, CBS Newspath reallocated channels fed from inside the convention to offer SCPC coverage of events taking place elsewhere in the city. Mobile trucks some using Scopus’ E-1710 platforms facilitated these transmissions.
