This document establishes the method of signalling the specific location referencing used by all TPEG2 applications that require detailed location information to be delivered to client devices such as TPEG2-TEC. The TPEG2-location referencing container (TPEG2-LRC) is described and shows 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 the present ISO series and the internal location referencing methods defined as parts of this series.
