Abstract:
Viewers of video on demand (“VOD”) programs are automatically presented with Emergency Alert System (“EAS”) information during an invocation of the EAS system. A VOD Support System receives notification of an EAS event and directs EAS information to be stored in a VOD Server. The VOD Support System then invokes a function in the VOD Server, causing the VOD server to suspend all active VOD streams and, instead, stream out the EAS information comprising a preamble and emergency information identified by the VOD Support System. Upon completion of streaming this information, the VOD Server will automatically resume each of the VOD programs previously suspended. VOD viewers watching a VOD session that is interrupted by an EAS test are thus automatically returned to their VOD programming at the point where their program was interrupted.
