4. Video Compression. It would take about 210Mbps of bandwidth to carry an
uncompressed video signal with the associated stereo audio channels. Obviously, this
is unreasonable in a CATV system so we must find a way to shrink the bandwidth
requirements while MAINTAINING a high quality signal. We call this Video
Compression. The most popular and versatile method is called MPEG.
a. MPEG1 – VHS quality, the original, low cost method. Not suitable for most
CATV applications. Good for PEG channels, city hall video, video arraignment
b. MPEG2 – Broadcast TV & DVD quality. The number of bits coded for
Luminance, Brightness and Chrominance is indicated by 4.2.0, 4.2.2 or 4.4.2 for
6bit, 8 bit and 10bit coding respectively. 10 Bit is used in post production studios
to produce TV commercials and HDTV programming. 8Bit is often used in TV
broadcasting for commercials, and 6 bit is the standard definition [SD] found in
DBS satellite, DVD disks and Cable TV.
c.
MPEG4 – Low Bit Rate Video. Used in Video Games, also for use over the
Internet, DSL or T1 lines for real time video conferencing and video
streaming. Uses a fraction of the bandwidth of MPEG2.
THE NEW
STANDARD FOR QUALITY IN LOW BIT RATE VIDEO
5. Radiant RM1100. The Radiant RM1100 series is an MPEG4 Encoder and Decoder as
well as a REMOTE CONTROLLER for centralized Set Top Boxes, Laser Disk Players,
Security & Surveillance Systems, VCRs and any other device that can be controlled by
an Infrared Remote Controller.
a. The RM1100 breaks new ground in providing Cable TV Systems Operators and
Telephone Companies new opportunities to generate revenue by delivering video
and audio over as little as 100kbps
b. The RM1100 is an Ethernet Attached APPLIANCE. It conforms to all industry
standards and will work on any Local, Wide or Metro Area Network
[LAN/WAN/MAN]
c. The RM1100 works with YOUR LAN and will throttle back automatically [this is
user selectable] if the network link gets congested. Conversely, the RM1100 can
be configured to set priority to all packets leaving the device, guaranteeing
throughput in networks where Quality of Service [QoS] Packet Prioritization is
available.
d. The User has the ability to CHOOSE what is more important, Bandwidth or
Quality. Also you can configure the RM1100 to fix a set bandwidth, a set quality
level or let the system run in automatic mode.
e. The RM1100 is designed to work with the customer’s own PC [using Radiant
“RM-PC Vision” Software] or with the Radiant RM View Station.
6. Radiant “RM View Station”
The Radiant RM View Station includes a dedicated PC that:
a. Allows the client to view and control the video & audio on the PC screen
b. Provides for connections to a large screen TV Monitor or a Projector
c. Is Ethernet attached and is assigned an IP address on the customer LAN
d. Controls an RM1100 in the Head End or Central Office
e. The RM View Station delivers Superior Quality since it is optimized for the
system and the application and runs no other programs.
