Cisco Model 6275 Frequency Agile Demodulator (NTSC) Data Sheet
Description
The Continuum DVP
Models D6238 and D6239 8VSB
Demodulators from Scientific-Atlanta, enable 8VSB
television signals to be inserted into digital cable systems.
Both the Model D6238 and Model D6239 will process an
off-air HDTV 8VSB television signal providing an ASI
output for injection into a QAM modulator. The Model
D6239 also includes a built-in multiplexer allowing for the
combining of two 8VSB broadcast signals into a single
38 Mbps ASI output for use in 256 QAM cable applications.
Using a standard web browser via the RJ-45 Ethernet port, you can set up all parameters in just a few minutes.
Parameters include local station selection, alarms, and even PSIP processing.
You can select certain program elements contained in the stream for deletion. For example, if you choose to
completely delete private data services from a particular stream you can simultaneously modify channel numbers to
allow correct channel mapping. In another example if both HDTV and SDTV signals are present in the stream, you
can just pass the signal you want to inject into your cable system.
Both the Model D6238 and Model D6239 provide quality monitoring of carrier, and transport stream via web
interface. Warning and major alarm signals are also provided via contact closures. Plus, the Model D6239
includes switching to a local alternate ASI program.
Users who require advanced features like ASI inputs and onboard remux should use the Model D6239.
