GIGe
Gigabit Ethernet High speed Ethernet standard for transmitting data at one gigabit per
second. All switches in the GIGe (video) network must be rated to pass this level of traffic.
IGMP Internet Group Management Protocol. Used by Ethernet Switches and end devices to
manage multicast video on IP networks.
HD High Definition
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.
Media Server A media server converts video and audio from HDMI or Composite video and creates an
IP stream that can be modulated on the RF network via the QAM 20. There are several
manufacturers of Media servers that are compatible with the COM3000, contact you
Distributor.
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 AT&T /
DIRECTV HD signals are MPEG4 contained in a MPEG2 transport stream. 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.

Pro:Idiom Pro:Idiom is an industry accepted hardware based 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
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
