Network
This network, set up and maintained by the system operator or property owner,
distributes television signals via RF or IP technology. Traditional analog RF plants often
are in need of repairs and upgrades before they will pass digital HD programming. RF
levels and signal to noise ratios (Modulation Error Rate) should be tested to industry
standards. IP systems require technicians proficient in IP switch configurations,
specifically multicast networks utilizing Internet Group Management Protocols (IGMP).
PSIP
Program and System Information Protocol. Signals included in a digital TV signal define
the display channel. For example, an off-air channel may be broadcast on UHF ch 38 but
the station call letters are ch 7. PSIP data instructs the TV to display a virtual channel 7 on
the TV rather than the physical channel 38. PSIP data also includes current and future
programming information.

The QAM20, shown above in Figure 4 is an Edge QAM256 modulator capable of outputting up to
48 QAM carriers.
➢QAM20 ships from the factory authorized for 16 QAM carriers. The unit is upgradable in 2 QAM
increments via optional software license (SWQAM2) to a maximum of 48 QAM output carriers.
➢Depending on the DIRECTV channel bit rate, each QAM carrier may support up to three HD or eight
SD program channels.
➢Accepts IP input from:
oCOM51 Card
oCOM46 Card
oExternal MPEG2 transport stream (.TS)
➢Each QAM is individually agile and able to output to any carrier frequency in a 128-channel range
oModeLow enables carriers 1 to 128 (57MHz to 819MHz) output
oModeHigh enables carriers 26 to 158 (237MHz to 999MHz) but not 95 to 99
➢New User interface makes configuring channel line ups easier than the previous QAM6.
