and digital televisions. As an uncompressed connection, HDMI is independent of
the various digital television standards used by individual devices, such as ATSC
and DVB, as these are encapsulations of compressed MPEG video streams (which
can be decoded and output as an uncompressed video stream on HDMI).
LNB
Stands for Low-Noise Block converter. This is the (receiving, or downlink) antenna
of what is commonly called the parabolic satellite dish commonly used for satellite
TV reception. The LNB is usually fixed on or in the satellite dish. The purpose of
the LNB is to take a wide block (or band) of relatively high frequencies, amplify
and convert them to similar signals carried at a much lower frequency (called
intermediate frequency or IF). These lower frequencies travel through cables
with much less attenuation of the signal, so there is much more signal left on the
satellite receiver end of the cable. It is also much easier and cheaper to design
electronic circuits to operate at these lower frequencies, rather than the very high
frequencies of satellite transmission.
PID
Stands for Packet Identifier. This is a set of numbers identifying stream packets
contained within a single data stream
Polarization
The orientation of the electrical and magnetic fields of a signal. Satellites use mainly
vertical and horizontal polarization.
S/PDIF
Stands for Sony/Philips Digital Interconnect Format. A common use for the S/PDIF
interface is to carry compressed digital audio as defined by the standard IEC 61937.
This mode is used to connect the output of a DVD player to a home theater receiver that
supports Dolby Digital or DTS surround sound. Another common use is to carry
uncompressed digital audio from a CD player to a receiver. This specification also
allows for the coupling of personal computer digital sound (if equipped) via optical or
coax to Dolby or DTS capable receivers.
Smartcard
A pocket-sized card with embedded Integrated Circuits which can process data. It can
receive input which is processed and delivered as an output. The card may embed a
hologram to avoid counterfeiting. It is used for accessing encrypted TV channels or
services.
Teletext
A television information retrieval service developed in the United Kingdom in the
early 1970s. It offers a range of text-based information, typically including national,
international and sporting news, weather and TV schedules. Subtitle (or closed
captioning) information is also transmitted in the teletext signal, typically on page 888 or
777.
YPbPr
A color space used in video electronics, in particular in reference to component video
cables. YPbPr is the analog version of the YCBCR color space; the two are numerically
equivalent, but YPBPR is designed for use in analog systems whereas YCBCR is
intended for digital video. YPbPr is commonly called "component video", but this is a
misnomer, as there are many other types of component video (mostly RGB with sync
either on green or one or two separate signals).
YPbPr is converted from the RGB video signal, which is split into three components, Y,
PB, and PR.
* Y carries luma (brightness) and sync information.
* PB carries the difference between blue and luma (B - Y).
* PR carries the difference between red and luma (R - Y).
Sending a green signal would be redundant, as it can be derived using the blue, red and
luma information.
