Standard-Definition EAS Encoder
The transition to digital TV distribution provides new methods of implementation. Drake has developed a specialized SDE24EAS encoder module to digitize legacy analog EAS (Emergency Alert System) receivers for digital distribution.
EAS is national public warning system in the United States. The system may be used by federal, state or local authorities to deliver important emergency information. EAS is designed to override all channels with the EAS information. Most EAS systems have been analog based.
The EAS receiver activates the EH244 encoder host EAS mode by providing a contact closure. Once EAS is activated the Encoder Host will replace all PIDS with the encoded EAS message from the SDE24EAS encoder so that all programs contain the message.
