scope:
This ETS specifies the data syntax to be used by Videotex services for conveying photographic data.
In general, it applies to the interchange of photographic data via storage or transmission media.
The ETS is applicable to Videotex terminals connected to various types of telecommunication networks including; a Public Switched Telephone Network (PSTN), a Public Switched Packet Data Network (PSPDN) or an Integrated Services Digital Network (ISDN). For the ISDN case, these terminals will typically support "ISDN Syntax-based Videotex" (see ETS 300 079 [3]).
The syntax allows for some private extensions beyond the transmission of still pictures. For example, a provision has been made for the transmission of a "difference" image to allow a slow scan television type of application.
