to put "C" band frequencies on Ku band STB


For Kalaignar channels' on "Intelsat-17" "C" band ,using Ku-band STB:

5150-3845+09750 = 11055 MHz with LNB Freq: 09750 MHz and 22K:OFF
OR
5150-3845+10600 = 11906 MHz with LNB Freq: 10600 MHz and 22K:ON

A Universal Ku-band LNB works only for Low band: 10.70 to 11.70GHz & High band: 11.70 to 12.75GHz

about free to air (FTA) channels..

Free-to-air channels are those channels that are transmitted without encryption, so that any FTA receiver can display them on your television to watch. Most FTA channels are digitally compressed with the MPEG-2/DVB standard,so modern FTA receivers are able to decode that standard.Now MPEG4/DVBS2 as well as HD standard channels also started as FTA channels from some satellites like intelsat 17.

A FTA receiver, a dish of sufficient size, a Low-Noise Block Filter (LNBF), and the cables to connect them are needed in order to receive FTA. For most FTA channels (those using Ku-band), a 30-inch dish is necessary. Only a few FTA channels are available using smaller, 18-inch dishes. There are even more channels available with a C-band (6-foot) dish, but we will not go over them here.

A wide variety of channels are available, including broadcast channels, public interest channels, and foreign language programming. New channels come and go all the time. For the complete FTA satellite or channel list, please visit lyngsat.com.

The broadcasters pay for the FTA channels. Some are using the satellite to send their signal to cable companies. Some foreign countries subsidize television for their citizens living in North America. You can't count on anything in particular being there, but you can always count on something being there.

Free-To-Air satellite equipment is not plug-and-play. You absolutely need to have knowledge about setting up this equipment or know someone who does.

There are many FTA SATELLITE FORUM sites on the internet that have all of the information that you could ever need. Every question you can think of has already been answered in these forums. Most of these forums are free.

Most Free To Air satellite content is broadcast on either C Band or Ku Band. C Band is the original frequency allocation for communications satellites. C Band uses 3.7 to 4.2Ghz for uplink; 5.9-6.4Ghz for downlink. C band requires a large dish, usually 6 feet in diameter. C band dishes vary between 3 feet and 9 feet in diameter, depending upon signal strength. The higher frequencies of Ku Band are more vulnerable to signal quality problems caused by rainfade than C Band satellite frequencies. The Ku Band uplink uses frequencies from 14 to 14.5GHz; the downlink uses frequencies between 10.7 and 12.7GHz. Ku Band dishes can be much smaller than C Band dishes. Ku Band dishes vary from 2 feet to 5 feet in diameter. Ku Band satellites typically transmit with far more power than C Band satellites. At one time, most Free To Air satellite programming was transmitted via C Band, but FTA programming has now migrated primarily to Ku Band.

CI stands for Common Interface. It is a standard, agreed to by manufacturers of satellite receivers, to interface a digital receiver to a Conditional Access Module (CAM), where the purpose of the CAM is to decipher encrypted signals. There are various Conditional Access Systems and therefore different CAMs, such as Viaccess, Irdeto, Cryptoworks, Nagravision, Mediaguard, Conax... to view Pay-TV contents

HDTV stands for High Definition TeleVision. To give you an idea what the difference between HDTV and SDTV (current conventional TV): SDTV broadcasts with a resolution of 720 lines each with 576 pixels. In total, an SDTV screen is composed of more than 400,000 pixels (720 * 576). A full HDTV broadcasts in a resolution of 1080 pixels by 1920 pixels image. In total, a full HD signal consists of more than 2 million pixel image.A full HD television signal broadcasts in a five-fold compared to a resolution analogue PAL television signal.

Full HD resolution signal has a five-fold compared to a PAL signal. Another major benefit of HDTV is implicitly much improved detail of the colors, something that significantly contributes to the feeling of a real experience. Whether analog or digital broadcasting, there is a five-fold bandwidth to such a high quality image mode also discussion.

The difference between HD (Full HD), HD Ready the number of pixels, also known as pixels. HD has a resolution of 1920 × 1080 pixels more than HD Ready 1280 x 720. An HD-ready screen should meet the following minimum requirements: - At least 720 lines - Input YPbPr, HDMI / HDCP (or DVI + HDCP) A full HD display must meet the following requirements - Minimum 1080 pixels - Input YPbPr, HDMI / HDCP (or DVI + HDCP)
