GLOSSARY OF TERMS
DVB-T the Digital Video Broadcasting
standard that defines modulation and error 
correction in terrestrial transmissions. MPEG-2 
is used as the transport stream.
EPG - Electronic Programme Guide – a 
service that displays detailed information 
about current and future programmes on the 
television screen.
FTA - Free-to-air – uuencoded radio and 
television channels that may be received on 
any television set.
STB - Set-top box – an electronic device 
connected to the television set, which 
processes the signal received from the 
ground-based, cable or network satellite 
antenna. It enables the playback of video and 
sound.
HD (High Definition) - Used to describe 
video content that is in one of the high 
definition video formats. These are broadly 
720i/p and 1080i/p. The 720 or 1080 refers to 
the number of horizontal lines used to define 
the picture and the “i” and “p” refer to 
“interlaced” or “progressive scan”. Ordinary, 
“SD / Standard Definition” TV used 576 lines 
(PAL standard).
Full-HD - HD television standard for 1080p 
quality video, with 1080 horizontal lines.
HD Ready - HD television standard for 720p 
quality video, with 720 horizontal lines.
Aspect ratio: The ratio of vertical and 
horizontal sizes of a displayed image. The 
horizontal vs. vertical ratio of conventional 
TVs is 4:3, and that of widescreens is 16:9.
JPEG: A very common digital still picture 
format. A still-picture data compression 
system proposed by the Joint Photographic 
Expert Group, which features small decrease 
in image quality in spite of its high 
compression ratio.
XviD: MPEG-4 based video compression 
technology, that can shrink digital video to 
sizes small enough to be transported over the 
internet, while maintaining high visual quality.
H.264: is a next-generation video 
compression format. H.264 is also known as 
MPEG-4 AVC. Developed for use in high 
definition systems such as HDTV, Blu-ray as 
well as low resolution portable devices, H.264 
offers better quality at lower file sizes than 
both MPEG-2 and MPEG-4 ASP (DivX or XviD). 
H.264 is sometimes referred (erroneously) as 
x264 – x264 is the name of a popular 
freeware encoder for the H.264 format. H.264 
is also sometimes referred to as MP4, again 
this is technically incorrect. MP4 is a container 
format much like AVI or MKV and it can be 
used to “house” many different types of 
compression codecs, not just H.264.
Container. The multimedia container file is 
used to identify and interleave different data 
types. Simpler container formats can contain 
different types of audio codecs, while more 
advanced container formats can support 
multiple audio and video streams, subtitles, 
chapter-information, and meta-data (tags) — 
along with the synchronization information 
needed to play back the various streams 
together. There are many container formats, 
such as AVI, Matroska (MKV), MOV, MP4, 
OGM, WAV, etc.
PCM (Pulse Code Modulation): A system 
for converting analog sound signal to digital 
signal for later processing, with no data 
compression used in conversion.
S/PDIF - Format for carrying audio digitally 
over either optical (TOSLINK) or electrical 
(Coaxial) cable. Can carry high quality DTS or 
Dolby Digital audio.
