[opendtv] Sinclair Station Taps Rohde for Mobile DTV Install

Good choice, since WNUV currently supports only one program in their 
underutilized multiplex.

This part:

"The R&S AEM100 comes with the SFN function already integrated. This function, 
which can be optionally activated, makes it possible to supply the ATSC Mobile 
DTV transport stream from the multiplexer to several transmitters, allowing for 
simultaneous transmission on the same frequency in SFNs."

is confusing. It seems to say that the SFN can be for just the mobile 
stream(s). I don't think that's possible.

These M/H deployments are also impressively quick, just like the DVB-T2 HD 
streams in the UK. The standard was only ratified last week, IIRC. The ION 
station in the DC market has been transmitting M/H for some time now, but not 
in a SFN.

Sinclair Station Taps Rohde for Mobile DTV Install
10.22.2009.

WNUV-DT, a Sinclair-owned station in Baltimore, has installed the industry's 
first fully compliant ATSC Mobile DTV multiplexer and exciter for the new A/153 
Mobile DTV Station.

Rohde & Schwarz supplied the gear, including its new SX800, a full frequency 
agile exciter already used in the newest ATSC and NTSC medium-power air-cooled 
and high power liquid cooled R&S transmitter systems. It is also available for 
use in transmitters from other manufacturers, supports all worldwide TV 
broadcast standards and also can be deployed for ATSC Mobile DTV and SFN 
networks.

The heart of the system is the new R&S AEM1000 emission multiplexer, which 
includes the IP encapsulator, a signaling generator and the Mobile DTV 
multiplexer. The single RU high product fully supports ATSC Mobile DTV and SFN 
operation and can be integrated into existing installations, leaving the 
standard ATSC A/53 multiplexer in place.

The R&S AEM100 comes with the SFN function already integrated. This function, 
which can be optionally activated, makes it possible to supply the ATSC Mobile 
DTV transport stream from the multiplexer to several transmitters, allowing for 
simultaneous transmission on the same frequency in SFNs. This allows network 
operators to address coverage problems to serve more viewers without having to 
apply for additional frequencies.

The complete ATSC Mobile DTV functionality is configured controlled and 
monitored using a web browser locally or remotely. All commands for automatic 
monitoring and for the instrument settings are available over an SNMP interface.
