EWBS and IoT
EWBS (Emergency Warning Broadcast System) ad IoT (sensors)
The Emergency Warning Broadcast System (EWBS) incorporates new technology into early warning systems alongside traditional methods of communication. It is a system in Digital Terrestrial Television Broadcasting (DTTB) Service to alert and guide the public of an ongoing emergency situation by delivering warning information through an audible sound and the superimposition of data to various types of ISDB-T receivers that are automatically activated.
EWBS is a remote activation system for Radio & TV that transmits alert/warning information to viewers and listener about a relevant disaster that has been detected and measured by IoT sensors and other detection sources. EWBS is a feature of the Integrated Services Digital Broadcast-Terrestrial (ISDB-T) system, which is initially created by Japan. The ISDB-T standard has been adopted by more than 15 countries in recent years.
EWBS signal transmitted by broadcasters activate EWBS-ready receivers and show emergency information. Broadcasters convey the emergency information by transmitting a text message using Superimposed function.
MAIN FEATURES:
- Complete signaling of the EWBS according to ISDB-T Harmonization Document Part 3 (Revision November 2015).
- Simple and intuitive operation, does not require advanced knowledge of the ISDB-T standard.
- Compatible with VideoSwitch BTS Compression / Decompression system.
- Generates EWBS TMCC Flags ON / OFF, Signal Level 0/1, Country Code, Area Codes, Emergency Descriptors and Superimpose PIDs.
- Enables centralized operation with EWDT table (Emergency Warning Distribution Table) via DVB satellite or directly to DMUX equipment.
- Optimize satellite bandwidth: it is supported with Cable Operators and DTH (does not require a second satellite link).
- Allows you to work with encrypted signals in the satellite.
- Emergency warning by a non-saturable medium (E.g.: cell phone network).
IoT (Internet of Things)
IoT (Internet of Things) sensors for emergency detection systems are devices that detect and measure different types of physical or environmental conditions and transmit that data over the internet or a local network. These sensors are an essential component of IoT systems, enabling the collection of real-world data for monitoring, automation, and decision-making purposes.
Here are some common types of IoT sensors and their functions:
- Earthquake sensors: Detect and measure the intensity of seismic activity.
- Flooding sensors: Detect water flooding situations.
- Temperature sensors: Measure ambient or object temperature, used in HVAC systems, industrial processes, and environmental monitoring.
- Humidity sensors: Measure the amount of moisture or water vapor in the air, used in agricultural applications, climate control, and more.
- Pressure sensors: Detect and measure pressure levels, used in automotive systems, industrial machinery, and weather monitoring.
- Light sensors: Measure the intensity of light or illumination, used in smart lighting systems, photography equipment, and daylight harvesting systems.
- Motion sensors: Detect movement or presence, used in security systems, smart homes, and occupancy monitoring.
- Proximity sensors: Detect the presence of nearby objects without physical contact, used in robotics, automation, and safety systems.
- Gas sensors: Measure the concentration of various gases (e.g., carbon monoxide, methane, and air quality), used in environmental monitoring and industrial safety applications.
