Embodiment Construction

[0029] In general, this disclosure describes techniques for signaling (or signaling) emergency alert messages. In particular, the techniques described herein may be used to signal information associated with content contained within an emergency alert message and / or other information associated with an emergency alert message. In some cases, receiver devices may be able to parse information associated with emergency alert messages and cause presentation and / or rendering of digital media content to be modified so that corresponding emergency message alerts are more apparent to users. For example, a receiver device may be configured to shut down or temporarily suspend an application if signaling information indicates the presence of a particular type of content contained within an emergency alert message. It should be noted that although in some examples the techniques described herein are described in terms of emergency alert messages, the techniques described herein can be app...

Abstract

A device may be configured to receive a low level signaling emergency alert message fragment from a broadcast stream. The device may parse syntax elements included in the emergency alert message fragment. The device may determine whether to retrieve a media resource associated with the emergency alert message based on the parsed syntax elements.

Description

technical field [0001] This disclosure relates to the field of interactive television. Background technique [0002] Digital media playback capabilities can be included in a wide range of devices, including digital televisions - including so-called "smart" TVs, set-top boxes, laptop or desktop computers, tablets, digital recording devices, digital media players, video games devices, cellular phones – including so-called “smart” phones, dedicated video streaming devices, etc. Digital media content, such as video and audio programming, can originate from a number of sources including, for example, over-the-air television providers, satellite television providers, cable television providers, online media service providers - including so-called streaming service providers Wait. Digital media content may be delivered over packet-switched networks, which include bidirectional networks, such as Internet Protocol (IP) networks, and unidirectional networks, such as digital broadcas...
