TPEG2 - Wide Area Broadcast

Description:

This solution is used within Australia, Canada, the E.U. and the U.S.. It combines standards associated with TPEG2 with those for C-X: Wide Area Broadcast. The TPEG2 standards include upper-layer standards required to support multi-modal information services.. The C-X: Wide Area Broadcast standards include lower-layer standards that support one entity broadcasting information to all wireless devices over an area that covers at least a metropolitan area without any expectation of acknowledgement or response; security is provided by the upper-layers.
