DiSEqC (Digital Satellite Equipment Control)
A standard through which it is possible to let a DiSEqC compatible receiver send a signal over the RF cable to a switching device to switch between different LNBs or dishes. The DiSEqC uses the 22KHz signal to control the switching device.
Programme Guide (Electronic Programme Guide, EPG)
A electronic program guide (EPG) that comes with the broadcast to a particular satellite, note that every station fills the EPG differently or not, so differences in the EPG are not necessarily receiver errors.
Frequency
The number of cycles or events per one second, which is expressed in the unit of hertz
FTA (Free-To-Air)
An unscrambled broadcast, which you can view without additional payments to a service provider.
Hi-Fi (High Fidelity)
The characteristics of audio devices that can play back all the audio frequencies of the human, which is the range of 16Hz~20KHz, uniformly from the low frequency to high frequency. Sometimes it is used to indicate good quality of an audio device such as stereo tape recorder.
LNB (Low Noise Block)
An electronic unit mounted on the satellite dish. It receives the signals reflected by the dish and converts them to signals that can be used by this product.
OSD (On Screen Display)
The function that displays the information about the monitor that the user needs or has to know on the screen directly. OSD information includes brightness, contrast, tuning, RGB adjustment, and screen size and positions (top, left, width, and height), and so on.
OTA (Over The Air)
Means that software downloads where the manufacturer reserves the right to decide when and where to release them through satellite system.
SCART
A
S/PDIF (Sony/Philips Digital Interface format)
Standard format for digital audio output. It outputs audio signals directly as digital audio signals without changing into analog signals because conversion into analog signals can degrade signal quality.
Transponder
An automatic device that receives amplifies and retransmits a signal on a different frequency.
