ST.RE.E10228.1
ATM Asynchronous Transfer Mode: A connection orientated, cell based, data transport
technology designed for Broadband ISDN (B-ISDN). It provides a circuit-switched bandwidth-
on-demand carrier system, with the flexibility of packet switching. It offers low end-to-end
delays and (negotiable on call set-up) Quality of Service guarantees. Asynchronous refers to
the sporadic nature of the data being transmitted. Cells are transmitted only when data is to
be sent, therefore the time interval between cells varies according to the availability of data.
ATSC Advanced Television Standards Committee: An organisation founded in 1983 to research
and develop a digital TV standard for the U.S.A. In late 1996, the FCC adopted the ATSC
standard, the digital counterpart of the NTSC standard.
B3ZS Bipolar with Three Zero Substitution: A method of eliminating long zero strings in a
transmission. It is used to ensure a sufficient number of transitions to maintain system
synchronisation when the user data stream contains an insufficient number of 1s to do so.
B3ZS is the North American equivalent of the European HDB3.
Backward
Compatibility
Refers to hardware or software that is compatible with earlier versions.
BAT Bouquet Association Table: Part of the service information data. The BAT provides
information about bouquets. It gives the name of the bouquet and a list of associated
services.
baud rate The rate of transfer of digital data when the data comprises information symbols that may
consist of a number of possible states. Equivalent to bit-rate when the symbols only have two
states (1 and 0). Measured in Baud.
BER Bit Error Rate: A measure of transmission quality. The rate at which errors occur in the
transmission of data bits over a link. It is generally shown as a negative exponent, (e.g., 10
-7
means that 1 in 10,000,000 bits are in error).
BISS Basic Interoperable Scrambling System: Non-proprietary encryption from EBU (Tech3290).
Bit-rate The rate of transfer of digital data when the data comprises two logic states, 1 and 0.
Measured in bit/s.
Block; Pixel Block An 8-row by 8-column matrix of luminance sample values, or 64 DCT coefficients (source,
quantised, or dequantised).
Bouquet A collection of services (TV, radio, and data, or any combination of the three) grouped and
sold together, and identified in the SI as a group. A single service may be in several bouquets.
B-Picture; B-Frame Bi-directionally Predictive Coded Picture/Frame: A picture that is coded using motion-
compensated prediction from previous I or P frames (forward prediction) and/or future I or P
frames (backward prediction). B frames are not used in any prediction.
BPSK Binary Phase Shift Keying: A data modulation technique.
Buffer A memory store used to provide a consistent rate of data flow.
BW Bandwidth: The transmission capacity of an electronic line such as (among others) a
communications network, computer bus, or broadcast link. It is expressed in bits per second,
bytes per second or in Hertz (cycles per second). When expressed in Hertz, the frequency
may be a greater number than the actual bits per second, because the bandwidth is the
difference between the lowest and highest frequencies transmitted. High bandwidth allows
fast transmission or high-volume transmission.
Byte-mode Each byte is delivered separately in the ASI Transport Stream, with stuffing data added
between the Bytes to increase the data rate to 270 Mbit/s. See DVB Document A010 rev. 1,
Section B3.3, (ASI) Layer-2 Transport Protocol.
CA Conditional Access: The technology used to control the access to viewing services to
authorised subscribers through the transmission of encrypted signals and the programmable
regulation of their decryption by a system such as viewing cards.
CAT Conditional Access Table: Part of the MPEG-2 Program Specific Information (PSI) data.
Mandatory for MPEG-2 compliance if CA is in use.
