SatcoDX Satellite ChartColumn Explanation |
What is "Ch #"?
| Ch # | Channel Number |
| Satellite operators use
a numbering system on the frequencies their
satellite transmits down to Earth. However, there is no worldwide
standard on how the numbers are assigned to the frequencies, thus each
satellite operator invents its own proprietary numbering system. In
certain areas such as North America, a unified numbering system is in
use. A satellite operator will often use a standard numbering system
across all the satellites in its fleet. Note: A channel number such as "40" might represent a certain downlink frequency on one satellite, a different frequency on another satellite, and another frequency on yet another satellite. |
|
What is "Freq. GHz"?
| Freq. GHz | Downlink Frequency in GHz (Giga Hertz) |
| The frequency the
satellite uses to beam the transmission down to
Earth. This is known as the "downlink" frequency - as opposed to the
frequency used to send the transmission to the satellite in the first
place, which is known as the "uplink" frequency. There are two main frequency bands in use; the C-Band with downlink frequencies in the 3 and 4 GHz range, and the Ku-Band with frequencies in the 10, 11 and 12 GHz range. 1 GHz = 1000 MHz = 1000000 kHz = 1000000000 Hz. (Hz = Hertz). Example: 3.456 GHz = 3456 MHz |
|
What is "Pol"?
| Pol | Polarization |
| One frequency can be
used twice by using two opposing polarizations, so
that the two signals on the two identical frequencies do not interfere
with each other. This doubles the actual number of channels that can be
transmitted in the satellite's frequency range. One way of transmitting a signal is in linear polarization, the other way by rotating circular polarization. For the latter, imagine that the signal is transmitted like the thread of a screw. Therefore, there are two polarization modes: "H" = Horizontal, and "V" = Vertical, for linear polarized signals "R" = Right hand circular, and "L" = Left hand circular, for rotating/circularly polarized signals Note: Sometimes in North America the expression "reversed polarity" is in use. Often, rotating signals are used in C-Band and linear signals in Ku-Band, but there are no rules to this. Usually - but not always - the frequencies in use on the opposing polarities are separated from each other to minimize any remaining influences. |
|
What is "Coverage"?
| Coverage | Satellite's Antenna Coverage Beam | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Some satellites beam
their programmes to Earth using a transmission
antenna that is designed such that the beamed signal covers the entire
part of the Earth visible from that satellite's location in orbit. Such
transmission antennas are called global. It most cases it makes more sense for a satellite operator to concentrate signals to a certain area on Earth, mainly that part of Earth where the intended recipients of TV, radio or data channels are at home. For example, since the target audience is usually at home on land and not out at sea on ships somewhere, it makes more sense to point a transmission antenna to the land masses of Earth rather than to the oceans. Most satellites have more than one antenna on board, combined with cleverly designed reflectors that enable the satellite's footprint to match a desired reception area. It is therefore important to know which frequencies are connected to which transmission antenna in order to know on what parts of the Earth signals can be received. SatcoDX contains unique maps of the coverage areas of each of these antennas. In the centre of those coverage areas reception is possible with smaller antennas than at the edges of these coverage areas. Outside of these coverage areas, reception is probably still possible but using more advanced equipment. Each of these coverage areas has been given a Coverage Code in 8-letter-format. The first three letters indicate satellite operator, the following three letters indicate type or version of satellite itself and last two letters define the individual antenna coverage area. This 8-letter-format Coverage Code, or just parts of it, like only the satellite operator, or satellite type, can be displayed with receivers using the automatic programming function of SatcoDX. The coverage codes are also used by the Profile and Wizard functions of the "SatcoDX World of Satellites" software to identify which transmissions are receivable at a specific location. The satellite operator codes are as follows:
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

| PACKAGE | Used to identify a package of channels |
What is "Frame Rate"?
Number of pictures (frames) per second (Hz). Most commonly used frame rates are 25 Hz (25 pictures per second) and 30 Hz.What is "Video Format"?
Chroma Sampling Rate, MPEG knows three variants: 4:2:0 being widely used, and 4:2:2 used for high quality feeds. 4:4:4 is not usedWhat is "Channel"?
| Channel | Channel Name |
| Name of television,
radio or data channel as it is known to the public. Newly added or unidentified channels may temporarily carry the name of the channel as broadcast on the satellite. |
|
What is "Aspect Ratio"?
Ratio of width against hight of picture. 4:3 widely used for regular transmissions, and 16:9 for high definition transmissions. 2.21:1 used for cinema transmissionsWhat is "Number of Pixels"?
Video Resolution is defined by the number of pixels in width by hight| PAL/SECAM | 720x576 704x576 544x576 480x576 352x576 352x288 |
| NTSC | 720x480 704x480 544x480 480x480 352x480 352x240 |
| HDTV | 1280x720 1920x1080 |
What is "Video Bitrate"?
Transport Stream Bitrate of the Video signal as measured off life stream by SatcoDX AutoScan Station, in Megabit per second (Mbps, or Mb/s)What is "Mode"?
| Mode | Transmission Mode | ||||||||||||||||||||||||||||||||||||
| This is the commonly
used name of the transmission mode/standard.
Analogue transmission technologies define colour mode such as PAL,
SECAM, NTSC, or sound mode such as Wegener. Digital transmission technologies define the norm, as MPEG-2, or Digicipher etc. Analogue technologies are less critical, and colour mode mainly refers to the television monitor connected to receiver. Digital technologies require a satellite receiver capable of receiving that particular mode. The list of modes is as follows:
|
|||||||||||||||||||||||||||||||||||||
What is "Audio"?
| Audio | Audio Subcarrier Frequency |
| This is for analogue
channels; this column shows the audio frequencies.
The video signal of a television channel is transmitted on the Channel
Frequency given in the "Freq. GHz" column. The accompanying sound
signal is transmitted at a subcarrier of that video (main) frequency. The audio subcarrier frequency is given in MHz (Megahertz). A single frequency entry in this column represents Mono sound, while two frequencies seperated by "&", represent Stereo sound. Two or more frequencies without "&", represent different Mono sound carriers. For digital channels this column gives the Teletext PID. |
|
What is "PMT"?
| PMT | Programme Map Table |
| Only applicable for digital transmissions. | |
What is "SR"?
| SR | Symbol Rate |
| Only applicable for
digital transmissions. The symbol rate is the speed at which the data on the transponder is transmitted, in thousands of symbols per second (ksym/sec). The symbol rate is sometimes expressed as Megasymbols per second (Msym/sec, also referred to as MBaud/sec). A symbol rate of 27500 ksym/sec is equal to 27.5 Msym/sec. |
|
What is "FEC"?
| FEC | Forward Error Correction |
| Only applicable for
digital transmissions. The FEC (Forward Error Correction) indicates how many Bytes are used for the actual signal, and how many for correction of errors. A FEC of 1/2 means that 1 Byte out of 2 is used for error correction, while a ratio of 7/8 means 7 Bytes are used for the actual signal, and only one for error correction. A FEC of 1/2 gives as perfect as possible reception, since every Byte containing actual signal is controlled by another Byte checking it. When a provider chooses a FEC of 7/8 it means he is not wasting any bandwidth at the cost of delivering a signal. The lower amount of error correction means that more sophisticated equipment at the receiving end (for example a more stable and sensitive LNB, or higher reserves with the dish) are needed compared to the same transmission using a FEC of 1/2. |
|
What is "V-Pid"?
| V-Pid | Video Program Identification |
| Only applicable for
digital transmissions. The Video PID defines the data substream containing the video signal. Radio signals, which by definition don't contain any video signal, carry the value 8191 (this means empty) in the Video PID. The SatcoDX charts do not carry this 8191 value to make the charts clearer, and because receivers will anyhow shut down the video when there is none. |
|
What is "A-Pid"?
| A-Pid | Audio Program Identification |
| Only applicable for
digital transmissions. The audio PID defines the data substream containing the Audio (either TV or Radio sound) information. |
|
What is "PCR/4DTV"?
| PCR/4DTV | PCR / 4DTV |
| Only applicable for
digital transmissions. The PCR (Programme Clock Reference) is used by receivers to synchronise the video and audio elements of the transmission. For 4DTV systems, this column is used to show the virtual channel number used by the channel. |
|
What is "SID"?
| SID | Service Identification |
| Only applicable for
digital transmissions. The Service Identifier is used by the receiver to identify a certain service within a transmission. |
|
What is "NID"?
| NID | Network Identification |
| Only applicable for
digital transmissions. The Network Identifier identifies a certain Network Provider. This enables the receiver to search for just those channels originating from this network provider. The NID is usually unique for each provider, which enables this receiver function to work. Occasional feeds, and channels intended only as feeds for broadcasters, often do not adhere to this rule and are broadcast instead with the default NID value in their equipment. |
|
What is "TID"?
| TID | Transponder Identification |
| Only applicable for
digital transmissions. The Transponder, or Transport Identifier identifies a certain transponder (unique for each transponder per network). This enables the receiver to search for only those channels on this particular transponder. |
|
What is "Audio Format"?
The way audio channels are transmitted :| Single | One single audio channel |
| Dual | Two independent audio channels |
| Stereo | Two dependent channels, one for left audio, the other for right audio |
| Joint | The two stereo channels joined as used in MP3 |
What is "Sampling Rate"?
The frequency of sampling the audio signals. Three variants are in use: 32, 44.1 and 48 kHzWhat is "Audio Bitrate"?
Transport Stream Bitrate of the Audio signal as measured off life stream by SatcoDX AutoScan Station, in kilobit per second (kbps, or kb/s)What is "Package Information"?
| Package Information | Package name for channel |
| This details the package name for the channel. It is used by the SatcoDX World of Satellites software to select channels from specific packages and providers. | |
What is
"First Time Seen by"
"Last Time Seen by"?
| First Time Seen | First Time Seen by SatcoDX |
| This is the date the channel was first observed and entered onto the SatcoDX Chart by a SatcoDX Monitoring Station. This timestamp is updated when a change is made to the channel's data, for example if the channel's PIDs are changed. The name of the Monitoring Station that logged the transmission or amended the data is listed with this timestamp. | |
| Last Time Seen | Last Time Seen by SatcoDX |
| This timestamp shows the date and time of the latest logged observation of the channel by a SatcoDX Monitoring Station. Where applicable, it shows the name of a SatcoDX Contributor who assisted SatcoDX with the channels details. | |
