Embodiment Construction

[0026] In general, this disclosure describes techniques for signaling information associated with notification messages, including, for example, emergency alert messages. Specifically, the techniques described herein may be used to signal the type of emergency alert message, timing information associated with the emergency alert message, and / or other information associated with the emergency alert message. In some cases, the recipient device is able to parse the information associated with the emergency alert message and cause the presentation / rendering of the digital media content to be modified such that the corresponding emergency message alert is more apparent to the user. For example, the recipient device may be configured to close or temporarily suspend the application if the signaling information indicates the presence of a particular type of emergency alert message. It should be noted that although in some examples the techniques described herein are described with res...

Abstract

A device may be configured to receive a low level signaling notification fragment from a broadcast stream. The device may parse the notification fragment. The device may determine whether an emergencyalert message is directly integrated into a media component of a service based on the notification fragment. The device may modify the presentation of the service based on the determination of whether an emergency alert message is directly integrated into a media component forming the service.

Description

technical field [0001] This disclosure relates to the field of interactive television. Background technique [0002] Digital media playback capabilities can be incorporated into a wide range of devices, including digital televisions - including so-called "smart" televisions, set-top boxes, notebook or desktop computers, tablet computers, digital recording devices, digital media players, video game devices, cellular Phones – including so-called “smart” phones, dedicated video streaming devices, etc. Digital media content (e.g. 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 transmitted over packet-switched networks, including bidirectional networks such as Internet Protocol (IP) networks and unidirectional networks such as ...
