DVS 706 The Carriage of Vertical Blanking Information Data in North American
Digital Television Bitstream. Based on the ETSI EN 301 775 standard and
provides extensions for the carriage of VBI data. VBI data is carried in
MPEG-2 packetized elementary stream (PES) packets as private stream 1,
which in turn is carried in MPEG2 transport packets. The Data_unit_ID
values identify the type of data as AMOL 1, AMOL II, or TV Guide. Data
encoded in the data fields are supposed to be transcoded into the VBI of
525 line video but may be interpreted directly by a decoder.
EBU European Broadcast Union.
ECM
Entitlement Control Message.
Private Conditional Access information that specifies control words and
possibly other stream-specific, scrambling, and/or control parameters.
ECMG ECM Generator
EDI Ethernet Data Input.
EIA 708-B Digital Television Closed Captioning specifies the standards for DTV
technology. DTV closed captioning is transported in the bitstream as a
logical data channel in MPEG-2 picture user data field of the DTV digital
bitstream (as defined in the ATSC A/53 and ISO/IEC 13818 standards). To
ensure compatibility, the transport channel is designed to carry analog
(EIA-608-B) and digital closed captioning (EIA-708-B).
EIT Event Information Table
A mandatory Digital Video Broadcast (DVB) SI table that transmits
information relating to the events in the MPEG transport stream.
Elementary Stream A generic term for a coded bit-stream, be it video, audio or other.
EMC Electromagnetic Compatibility.
EMM Entitlement Management Message.
Private Conditional Access information that specifies the authorization
level or services of specific decoders.
Encryption Encoding of a transmission to prevent access without the appropriate
decryption equipment and authorization.
EPG Electronic Program Guide.
Provides users of television, radio, and other media applications with
continuously updated menus displaying scheduling information for
current and upcoming programming.
ES Elementary Stream
A generic term for a stream of data of one particular type. Typically these
streams are of Video or Audio Types.
Ethernet The most widely used local area network (LAN) defined by the IEEE as the
802.3 standard.
ETSI EN 300 706 The European Television Standards Institute’s (ETSI) specification for
World Standard Teletext (WST).
