- Equivalent isotropically radiated power (EIRP), synonymous with effective isotropically radiated power, is an IEEE standardized definition of directional radio frequency (RF) power transmitted at equal power in all directions spherically from a theoretical point source.
It is differentiated from effective (or equivalent) radiated power (ERP) by use of absolute antenna gain in the calculation instead of relative antenna gain. The term "gain"is assumed to mean "antenna gain" and also "absolute" (referenced to isotropic) unless specifically stated to be relative. The gainis then multiplied by the poweractually accepted by the antenna to result in the actual EIRP. Power losses which occur prior to the antenna, e.g., in the transmission line or from inefficiency in the generator itselfare therefore not included in the calculation. - STB
A set-top box (STB) or set-top unit (STU), or nowadays known as a cable box is an information appliance device thatgenerally contains a TV-tuner input and displays output to a television set and an external source of signal, turning the source signal into content in a form that can thenbe displayed on the television screen or other display device. - CI module
the Common Interface is a technology which allows separation ofconditional access functionality from a digital TV receiver-decoder (Host) into a removable conditional-access module (CAM)
The hostis responsible for tuning to pay TV channels and demodulation of the RF signal, while CAM is responsible for CAdescrambling . The Common Interface allows them to communicate with each other.The Common Interface can be used for pay-to-view TVa module is used to interface between the pay-to-view card and the TV or device.
This allows manufacturers to install a single (common) interface into their devices rather than many.
It is a similar concept to USB. - Digital Video Broadcasting (DVB) is a suite of internationally accepted open standards for digital television.
DVB systems distribute data using a variety of approaches, including:
Satellite: DVB-S, DVB-S2 and DVB-SH
DVB-SMATV for distribution via SMATV
Cable: DVB-C, DVB-C2
Terrestrial television: DVB-T, DVB-T2
Digital terrestrial television for handhelds: DVB-H, DVB-SH
Microwave: using DTT (DVB-MT), the MMDS (DVB-MC), and/or MVDS standards (DVB-MS) - DVB-C stands for "Digital Video Broadcasting - Cable" and it is the DVB European consortium standard for the broadcast transmission of digital television over cable. This system transmits an MPEG-2 or MPEG-4 family digital audio/digital video stream, using a QAM modulation with channel coding.
- DVB-T2 is an abbreviation for "Digital Video Broadcasting Second Generation Terrestrial"; it
is the extension of the television standard DVB-T, issued by the consortium DVB, devised for the broadcast transmission of digital terrestrial television
DVB-SH ("Digital Video Broadcasting - Satellite services to Handhelds") is a physical layer standard for delivering IP based media content and data to handheld terminals such as mobile phones or PDAs, based on a hybrid satellite/terrestrial downlink and for example a GPRS uplink. The DVB Project published the DVB-SH standard in February 2007. - A conditional access module (CAM) is an electronic device, usually incorporating a slot for a smart
card, which equips an Integrated Digital Television or set-top box with theappropriate hardware facility to view conditional access content that hasbeen encrypted using a conditional access system. - What is
eMMC ?
TheeMMC solutionconsists of at least three components - the MMC (multimedia card) interface, the flash memory, and the flash memory controller - andis offered in an industry-standard BGA package.
Whereis eMMC used ?eMMC is suitable for high performance applications such as portable consumer electronic products for e.g. smartphones, digital tablets, multi-media players, PDAs, navigational systems and digital cameras.eMMC can thus be used for mobile devices, enhanced storage solutions and asreplacement for traditional storage media (i.e., HDDs).
What are the benefits ofeMMC ?
TheeMMC architecture integrating the flash memory controller in the same package simplifies the application interface design and frees the host processor from low-level flash memorymanagemen - SeeSecondly ,eMMC eliminates the need to develop interface software forall types of NAND memory by integrating the embedded controller into the memory chip and providing an easy-to-use memory solutions package for high-speed data transmissions by devices, such as mobile phones. - Transponder
In a communications satellite, a transponder gathers signals over a range of uplink frequencies and re-transmits them on a different set of downlink frequencies to receivers on Earth, often without changing the content of the received signal or signals. - Transmission Process
The outgoing transmission takes place at a very high frequency of 14,000 MHz (= 14 Gigahertz). To avoid any interference, the incoming signal (downlink)
- The Offset Dish Antenna, has its LNC not mounted centrally, but to the side of the dish. Because the LNC no longer obstructs the signal path, the dish has a better performance than the Prime Feed Focus dish. This allows the dish diameter to be smaller. Another advantage of this
type of dish is that it canbe positioned almost vertically,
- The Dual Offset Dish Antenna is an improvement on the Offset Dish antenna and has an even better performance. Its efficiency is about 80%. The main feature of this antenna is that it has two dishes: a larger receiving dish and a smaller dish facing the opposite direction which collects the signals from the larger dish and directs it to the LNC.
- Hybrid Broadcast Broadband TV (HbbTV) is both an industry standard (ETSI TS 102 796
[ 1]) and promotional initiative for hybrid digital TV to harmonise the broadcast, IPTV, and broadband delivery of entertainment to the end consumer through connected TVs (smart TVs) and set-top boxes.[ 2] The HbbTV consortium, regrouping digital broadcasting and Internet industry companies, is establishing a standard for the delivery of broadcast TV and broadband TV to the home, through a single user interface, creating an open platform as an alternative to proprietary technologies.[ citation needed] Products and services using the HbbTV standard can operate over different broadcasting technologies, such assatellite , cable, or terrestrial networks. - PVR
A digital video recorder (DVR) is an electronic device that records video in a digital format to a disk drive, USB flash drive, SD memory card, SSD or other local or networked mass storage device. The term includes set-top boxes with direct to disk recording, portable media players and TV gateways with recording capability, and digital camcorders.[ 1] Personal computersare often connected to video capture devices and used as DVRs; in such cases the application software used to record video is an integral part of the DVR.Many DVRs are classified as consumer electronic devices;such devices are sometimes referred to as personal video recorders (PVRs). - HD-capable MPEG-4 compatible satellite TV decoder
. This will then present the incoming satellite HD programming to the TV in either 720p or 1080i.
built-in ATSCtuner
You will gain nothing with an HDTV capable digital satellite TV decoder unlessit is connected to an HDTV set
HDTV MPEG-4 enabled satellite TV receiver.
Satellite TV receivers equipped with a digital video recording (DVR) optionthe integration of a built-in DVR with a satellite TV decodercertainly brings in a few significant advantages over the two-piece setup apart from saving valuable space in your equipment rack.
the functionality of the satellite receiver electronic program guide (EPG) would be well-integrated into the DVR's recording menu/scheduling system, thus makingrecording of future showsquick and easy.
Home-Theater-Capable
your digital satellite TV receiver should at least include an S-video output for standard definition, and component video or preferably an HDMI connection for HD programming. It should also incorporate a digital audio connection for Dolby Digital Surround if it does not include an HDMI output.
It is worth having a Picture-in-Picture (PIP) viewing option as the PIP feature found on most HDTVs today
http://www.practical-home-theater-guide.com/satellite-tv-decoder.html - Other features of recordable satellite receivers are USB compatibility so
external devices can be hooked up,as well as channel sorting, parental controls,picture in picture display, and subtitles.
http://www.ebay.com/gds /Your-Guide-to-Buying-a-Satellite-Receiver-/10000000177318405/g.html - Free-to-air (FTA) are television (TV) and radio services broadcast in clear (
unencrypted ) form, allowing any person with the appropriate receiving equipment to receive the signal and view or listen to the content without requiring a subscription, other ongoing cost or one-off fee (e.g. Pay-per-view). In the traditional sense, thisis carried on terrestrial radio signals and received with an antenna - The abbreviation LNB: Low Noise Block down-converter. It does not mean to block low noise!
The LNB is the device installed in front of the satellite dish andis connected with a cable (or more) to your decoder. The LNB receives the very low level microwave signal thatis transmitted from the satellite, amplifies it, changes the signals to the right frequency band and sends it with the cable to the decoder/receiver.
The expression low noise refers the quality of the first (input) electronic circuit.The quality is measured in units called;
Noise Temperature,
Noise Figure,
Noise Factor.The Noise Figure and Noise Factor are converted into Noise Temperature. An LNB with a low Noise Temperature is better than one with a high Noise Temperature.
Block refers to the conversion of a block of microwave frequencies received from the satellite thatare changed to a lower block of frequencies before sending it to the decoder. - The simple (single) LNB contains one or more local oscillators, referred to as LO running frequencies.
A universal LNB (dual band) has two local oscillators,
One to receive and convert the low band signals.
The other to receive and convert the high band signal
Multi-LNBs
A Quad LNB might have 4 outputs, for each polarization and each of two bands.
The LNB requires 18volt for Horizontal signals.
The LNB requires 13volt for Vertical signals. - Symbol rate
is the indication of the carrier modulation speed. Symbol rate tells how many transmission symbolsare modulated to the carrier per second. It is the rate of state changes on a communications circuit. - (FEC
) Forward Error Correction isa type of error correction which improves on error detection by enabling the receiver to correct errors oncethey are detected . This reduces the need for retransmissions. - A transponder is a wireless communication device that picks up an incoming signal and response to it. Transponder is a combination of the two words transmitter and
responder - FTA channel example:
Frequency: 10.773
Polarization: H (requires 18)
Symbol Rate: 22000
FEC: 5/6
Polarization note: (Our example = H)
Symbol rate (Our example = 22000)
FEC (Our example = 5/6)
- Signals transmitted by satellite can
be polarized in one of four different ways:
linear vertical

- polarization is a way to give transmission signals a specific direction. It makes the beam more concentrated. Signals transmitted by satellite can
be polarized in one of four different ways: linear (horizontal or vertical) or circular (left-hand orright-hand ). FSS satellites use horizontal and vertical polarization, whereas DBS satellites use left- and right-hand circular polarization.

There is a distinction between scrambling and conditional access, although for the viewer without a decoder the result is the same:
- LNC
- Fixed Service Satellites
Fixed Service Satellites (FSS) are satellites designed to transport telephone calls, data transmission and TV signals for broadcasting and cable organizations. Because these satellites have a relatively low power output of 10-20 watts per transmitted channel, it means that
Consumer Satellites - DBS and MPS
- A DBS, or Direct Broadcasting Satellite, is a satellite with high transmission powers, especially designed to transmit radio and TV programs. Because of its high power
( up to ten times the power ofa FSS satellite), its signals canbe received with smaller dish antennae of 25-40 cm in central receiving areas.
- Another kind of satellite is the Medium Powered Satellite (MPS), which is a satellite with a transmission power of 50 watts. The advantage of this
type of satellite is that it has more power thana FSS and its signals can thereforebe received much easier. Although it has less power than a DBS, its advantage over a DBS is that it allows the satellite to broadcast more programs. The ASTRA satellite is an example ofa MPS . MPS and DBS satellites are also referred to as consumer satellites.
- Fixed Dual FBC Tuners:
But before we look at that, let's look at the Dual Fixed FBC tuners. FBC stands for Full Band Capture. This new FBC tuner, will allow you to tune into 4 different frequencies per tuner,
To get the maximum from the Dual FBC tuners you will need to use a
Another great feature of the Solo 4K, is the Blindscan function, this is more for enthusiasts and advanced users that like to scan the skies for all the channels they can find. The Blindscan plugin will ask you to select which satellite you want to Blindscan, and then the receiver will do the rest. It's a great feature especially when looking for feeds, or scanning those satellites where channels move around frequently (this feature requires a driver update to get it working at time of writing this review).
And don't forget about the flexibility those 2 Fixed FBC tuners give you, 8 different transponders with only 2 feeds from the
