Keyword	Description
Download (service)	This is to deliver and store receiver software and common data for all receivers in the nonvolatile memory of the receivers for terrestrial digital broadcasting through the broadcasting wave.
Data broadcasting	This is a broadcasting service to combine simple video images, still images, characters, graphics, and subtitles with normal sounds. The target of data broadcasting in the digital satellite sound broadcasting is car reception (car navigation system) and mobile reception (cell-phone, PDA).
PSI	Abbreviation of Program Specific Information. This is an information necessary to choose a target program. It consists of PAT (Program Association Table), PMT (Program Map Table), NIT (Network Information Table) and CAT (Conditional Access Table). It is specified in the MPEG system standard and Ordinance of Ministry of Internal Affairs and Communications.
SI	Abbreviation of Service Information. This is a various information specified for the convenience of program choice. It is defined in Ordinance of Ministry of Internal Affairs and Communications. Its content is specified in the ARIB standard. In addition to extend the original parts of the ARIB standard, the PSI information of MPEG-2 is included.
SBR	Abbreviation of Spectral Band Replication This is a sound encoding method which is relatively effective in the case of a low bit rate. The information is stored in the fill element of ADTS and is used for the interpolation of high range of AAC. A receiver without the SBR function has backward compatibility to reproduce AAC.
CAS	Abbreviation of Conditional Access System. This is a system to control the viewing of service (programming channel) and event (contents).
Interactive communication (interactive data broadcasting service)	This is a service to combine data communication with broadcasting. It is assumed that the receiver has a function to communicate with data processing center by connecting it to a public telephone network, a PHS network, a mobile telephone network, ISDN, ADSL, FTTH, and CATV.
CDM	Abbreviation of Code Division Multiplex. This is a method to disperse the frequency band of a signal directly by a different spread code in every channel, and to multiplex plural channels in the same frequency band, followed by sending it out in a transmission channel.
TS	Abbreviation of Transport Stream. This is a transport stream specified in the MPEG-2 system standard (ISO/IEC 13818-1).
