CEA-2035 standardizes metadata elements describing Emergency Alert (EA) events to devices in a home network. Other standards define Emergency Alert signaling for digital cable receiving devices (ANSI/J-STD-042-A [2]) and for IPTV terminal devices (ANSI-0800012 [1]). Receiving devices in the home with access to 'commercial video' (sources of audio/video content provided as live or on-demand streams including, for example, terrestrial broadcast digital television) may wish to offer such content to a home network.
