Abstract: A method and apparatus are provided for sending an emergency alert message to a companion device. The apparatus includes a memory element and a processor coupled to the memory element. The processor is configured to receive an emergency alert message (EAM) in an advanced television systems committee (ATSC) signal. The processor is also configured to identify any companion devices that comprise a launcher application capable of being used by the apparatus. The processor is also configured to send a command to the launcher application capable of causing the launcher application to execute an application to an identified companion device that comprises the launcher application. The application is capable of accessing the EAM.

Abstract: A method for content delivery using dynamic adaptive hypertext transport protocol (HTTP) streaming (DASH) without using HTTP. The method includes receiving a media presentation description (MPD) file and one or more DASH segments by a client device. Information in the MPD file is used to filter the one or more DASH segments. The filtered DASH segments are stored in a segments buffer. Particular DASH segments are requested from the segments buffer by the client device based on the information.
