Masterkey & Plainmasterkey:
The coded, respectively uncoded 8-byte key, used to trigger certain card functions like “opening” the card.
The Masterkey can be calculated from the sum of the hexserial and the provider group.
So the mathematical formula is simply: hexserial + provider group = master key.
The Masterkey is also sometimes referred to as Key00. Whenever the Masterkey is written to the card, that is done uncoded (the plainmasterkey). The plainmasterkey is necessary for further processing of the key- and channel information.
One million cycles per second.
MMDS: Microwave Multipoint Distribution Services (see MUD)
A device that modulates a signal, for example, an analogue signal or an MPEG-2 transport stream onto a radio frequency carrier
A process in which a message is added or encoded onto a carrier wave. Among other methods, this can be accomplished by frequency or amplitude modulation, known as AM or FM, respectively.
Modified Original Smart Card. These are the original provider supplied smart cards.
MPEG is short for Moving Pictures Expert Group.
This is the organization that developed the MPEG standard.
MPEG comes in several versions:
– MPEG-1, mainly used for Video CD and MP3
– MPEG-2, the standard in digital TV, DVD and set-top boxes
– MPEG-4, the multimedia standard for the web
Multicrypt receivers are universal receivers that utilize a common interface to serve as a carrier for separate CAM’s. Multicrypt receivers have been developed under pressure of the market. Their flexibility lies in the possibility to host several CAM’s, thus enabling them to accommodate multiple coding systems.
MultiChoice Africa was born on the African continent and its history can be traced back to 1986 when a number of South African media companies formed Africa’s first pay TV channel, M-Net. From humble beginnings, M-Net grew much faster than anticipated.
Multiple Analog Component (MAC) Transmissions:
A video/audio/data transmission method that separates the data, chrominance and luminance components and compresses them for sequential relay over one television scan line. There are a number of systems in use and under development including A-MAC, B- MAC, C-MAC, D-MAC, D2-MAC, E-MAC and F-MAC.
Multiple Unit Dwelling (MUD):
MUD Microwave Multipoint Distribution Services – MMDS – A system for distributing television programs via terrestrial microwaves to very small receive dishes
The simultaneous transmission of two or more signals over a single communication channel. The interleaving of the luminance and chrominance signals is one form of multiplexing, known as frequency multiplexing. MultiChoice transmissions use time division multiplexing (TDM) whereby data streams are divided in time into interspersed data packets.
MUX – A device that takes the outputs from a number of encoders and multiplexes them together to form one data stream
A computer that controls the functions of a specific multiplexer pair in a compression system.
– Megabits per second. The standard unit of bit rate measurements, it represents 1,024 kilobits or 1,048,576 bits per second, although in practice this number is often rounded to 1,000,000 bits.
– Type of fixed-pixel projection television that uses a chip illuminated by a lamp to produce the image–as opposed to projection technologies that use CRTs. Examples include DLP, LCD, and LCoS rear-projection HDTVs.
– Motion Picture Association of America. Industry association for producers of motion pictures.
A low-loss coaxial cable connector used at the elevated microwave frequencies.
A coding system which is especially popular among Spanish and Turkish providers.
Nanos are commands, sent to the card in order to update the card.
– The resolution at which a TV or monitor is designed to display images. Image signals higher or lower than a specified native resolution must be converted to be displayed accurately. For example, a TV with a native resolution of 1080i can display 1080i images but may upconvert 480p images to 1080i. In contrast, a TV with a native resolution of 480p must downconvert a 1080i signal to 480p for display. CRT-based projection TVs can have more than one native resolution, but fixed-pixel displays such as LCD and DLP are limited to display one resolution and convert all others.
The National Television Standards Committee which created the standard for North American TV broadcasts.
NTSC Color Bar Pattern:
The standard test pattern of six adjacent color bars including the three primary colors plus their three complementary shades.
Negative Picture Phase:
Positioning the composite video signal so that the maximum level of the sync pulses is at 100% amplitude. The brightest picture signals are in the opposite negative direction.
Negative Picture Transmission:
Transmission system used in North America and other countries in which a decrease in illumination of the original scene causes an increase in the percentage of modulation of the picture carrier. When demodulated, signals with a higher modulation percentage have more positive voltages.
An unwanted signal which interferes with reception of the desired information. Noise is often expressed in degrees Kelvin or in decibels.
The ratio of the actual noise power generated at the input of an amplifier to that which would be generated in an ideal resistor. The lower the noise figure, the better the performance.
