Property
Distribution
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

specifically multicast networks utilizing Internet Group Management Protocols (IGMP).
PSIP
Program and System Information Protocol. Signals included in a digital TV signal that
instruct the TV to tune to a specific 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
look for ch 7 on UHF38. PSIP data also includes current and future programming
information.

3COM3000 Product Description
The COM3000 is the next evolution of the Technicolor Multiclient Solution product line. It builds
on the successful COM2000 system with additions of several new features.
A COM3000 system consists of the following three components:
➢COM400 chassis
➢COM51or COM51A tuner cards (maximum of 6 per chassis)
➢QAM20 modulator (maximum of 2 per chassis)
Configured with 6 COM51 receivers and one QAM20 a COM3000 can tune up to 138 AT&T /
DIRECTV channels.
➢Each COM51 card can receive up to 23 AT&T / DIRECTV channels.
➢COM51 cards will be incrementally licensed to tune between 8 (base package) and 23 channels in
increments of one channels per software upgrade.
➢QAM20 is capable of 48 QAM channel outputs incrementally licensed from 16 (base package) to 48
QAM channels in groups of 2 channels per software upgrade.
➢The channels are routed to an internal QAM20 modulator for RF output. In addition to the RF
output the COM51 chassis provides two 10 gigabit and two 1 gigabit ethernet ports.
The COM3000 system is shown below in Figure 1.
Figure 1 - COM3000
➢The original AT&T / DIRECTV broadcast video encoding format is preserved, and the output
transport stream is encrypted with the Pro:Idiom digital rights management (DRM).
➢Multiple COM400 chassis can be “stacked” to provide more than 138 output channels. Up to 16
chassis can be connected in the same system.
QAM 20s

➢The COM51 receiver cards are controlled and managed via an Ethernet connection within the
COM400 chassis.
oThe COM51 card includes a built-in web interface and can be configured using a web
browser.
oTo view high definition video from the COM3000 a TV or set top box equipped with
Pro:Idiom decryption technology must be used.
oStandard definition channels may be distributed in-the-clear.
3.1 Additional Features
In addition to high quality AT&T / DIRECTV programming, the COM3000 system offers
additional powerful features:
➢Optional Mediatune software upgrade offers switched matrix control capabilities for public space
environments.
➢Internal “home screen” channels can be configured to stream static image message screens direct
from the COM3000 system. No additional equipment required.
➢Vid Play utilizes a free program developed by Technicolor that will stream a MPEG2 transport
stream file from a low-cost PC (not provided) to the Technicolor QAM20 modulator for locally
originated video programming.
➢External content sources such as outboard transcoders and video encoders can be streamed to the
Technicolor QAM20 Modulator.
➢An electronic program guide that is fully customizable to system channel lineup and local
programming. PSIP data will pass to televisions and “map” the channels without intervention. (PSIP
interpretation is TV dependent, not all TVs respond to PSIP in the same manner. Test the TVs
before installing.
➢Guide.XML works in conjunction with Technicolor set back boxes to provide an interactive program
guide.
➢Interfaces with Emergency Alert Systems (EAS). Capable of sending locally originated streams to all
video channels for site specific emergency broadcast. (Only available on systems utilizing the
Technicolor QAM20 modulator).
➢Low power consumption. Typically, a fully loaded chassis draws <300 watts.
