This Technical Specification establishes the method of signalling the specific location referencing used by all TPEG1 applications that require detailed location information to be delivered to client devices such as TPEG1-RTM, TPEG1-PTI, TPEG1-TEC or TPEG1-PKI. The TPEG1-Location Referencing Container (TPEG1-LRC) is described, as well as how it is used to signal which specific location referencing method is in use for a particular TPEG Message. It is able to handle Location Referencing methods that are external to ISO/TS 18234 (all parts) and the internal location referencing method (TPEG1-LOC) defined in ISO/TS 18234-6.
