Hot-swappable The unit or device this term describes may be added to, removed from, or replaced
within the system it is a part of without powering anything down.
MPEG Moving Pictures Experts Group - A working group of ISO/IEC with the mission to develop
standards for coded representation of digital audio and video and related data.
Most commercial and some residential TVs support MPEG4 standards. All DIRECTV HD
signals are MPEG4. Many residential and some older commercial TVs will only support
MPEG2 signals and will require transcription from MPEG4 to MPEG2, or the use of a
setback box like the Technicolor DCI401MCS.

PC/VLC The COM2000 can accept streaming video from a networked PC running VLC, an open
source video software.

PID Packet Identification
Pro:Idiom Pro:Idiom is an industry accepted digital rights management encryption technology for
video signals broadcast in commercial establishments such as hotels, dormitories and
hospitals. All major programmers have accepted Pro:Idiom as an encryption method to
secure programming. Only televisions or set-back boxes with built in Pro:Idiom
encryption system decoders will be able to decrypt the signal.

Property This network, set up and maintained by the system operator or property owner,
Distribution distributes television signals via RF or IP technology. Traditional analog RF plants often
Network 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 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. In a COM2000 system your first RF channel may be 23.1. You can configure
PSIP within the COM2000 electronic program guide to map this programming to channel
2.

QAM6 Cards A board that installs in the upper left side of a COM360 Chassis. It converts the COM46's
IP-packetized streams to QAM-modulated RF for distribution throughout a property. The
board provides up to 12 QAM modulator channels in addition to a 10/100 Ethernet port.
The QAM6 base unit outputs 6 QAM channels each capable of carrying 3 HD or 8 SD
channels. Units are upgraded via 2 QAM licenses making the unit cost effective for
smaller applications. Each QAM channel can carry up to three HD or eight SD video
channels. A fully loaded COM2000 system broadcasting 48 HD channels requires 16 QAM
channels leaving additional capacity for additional services.
