MANILA, Philippines — Buying a television in the Philippines may soon mean getting more than sharper pictures and clearer sound.
Digital television sets sold in the country are required to have a built-in Emergency Warning Broadcast System (EWBS) capable of delivering alerts about impending or ongoing emergencies, according to the National Telecommunications Commission (NTC).
The development is part of the Philippines’ continuing transition from analog to digital terrestrial television, a shift that government officials say could strengthen the country’s disaster-warning capabilities.
TV Could Become Part of the Country’s Disaster-Alert Network
NTC Broadcast Services Division Chief Anna Liza D. Buenaviaje said digital TV receivers must be equipped with an emergency warning feature that can activate an alert even when the television is on standby.
That means compatible television sets could potentially become another channel through which Filipinos receive urgent government warnings—not just entertainment and news programming.
The system is designed to allow emergency information to be delivered to affected areas, with alerts capable of being localized or regionalized depending on the scope of the hazard, according to Department of Information and Communications Technology (DICT) Secretary Henry Aguda.
The Office of Civil Defense, operating under the National Disaster Risk Reduction and Management Council, is expected to provide the emergency content, while the DICT will handle the transmission infrastructure.
Why This Matters in a Disaster-Prone Philippines
The Philippines regularly faces typhoons, earthquakes, flooding, landslides and other hazards, making timely public warnings particularly important.
The EWBS concept is not entirely new.
The NTC’s regulatory framework for digital terrestrial television already defines an Emergency Warning Broadcast System as a mechanism that can alert and guide the public about an impending or ongoing emergency. The commission’s rules on the sale and labeling of ISDB-T receivers also form part of the regulatory framework governing compatible digital-TV equipment.
The country’s choice of Japan’s Integrated Services Digital Broadcasting-Terrestrial (ISDB-T) standard is also significant because emergency-warning capability was one of the features considered when the Philippines adopted the technology.
The Philippine Star reported in 2013 that the Japanese digital-TV standard was selected partly because of its built-in emergency alert capability, particularly relevant to a country frequently affected by natural disasters.
This Is Also About the Analog-to-Digital Switch
The emergency-alert feature is closely connected to the country’s broader migration away from analog television.
The NTC has been implementing rules for Digital Terrestrial Television Broadcasting since the mid-2010s. The commission’s framework provides for the transition from analog broadcasting to digital television, while subsequent regulations addressed the sale and labeling of ISDB-T receivers.
The latest government briefing says the Analog Switch-Off (ASO) began in Mega Manila on November 22, 2025, with the initial phase expected to run for 12 months unless extended by the NTC.
Government officials have stressed that the migration will not necessarily happen nationwide at exactly the same time.
DICT Secretary Aguda said the government is focused on achieving sufficiently high digital-TV penetration before shutting down analog services in an area. He also emphasized that digital television remains free-to-air, although households with older analog television sets will need a digital receiver or set-top box to receive digital broadcasts.
What Happens to Old TVs?
For households still using conventional analog television sets, the transition does not automatically mean they need to throw away their existing televisions.
An analog TV can continue to be used with a compatible digital TV receiver or set-top box, allowing it to receive digital terrestrial broadcasts.
However, consumers buying a new digital television should pay attention to whether the unit complies with Philippine requirements for ISDB-T digital receivers and carries the appropriate labeling.
The NTC has published regulations specifically covering the sale and labeling of ISDB-T receivers, reinforcing the need for consumers to check compatibility before purchasing equipment.
Digital TV Is More Than Better Picture Quality
The government is promoting the digital shift not only for improved television viewing but also because digital broadcasting can accommodate more services within available spectrum.
According to the PIA report, digital terrestrial broadcasting allows stations to transmit more programs while delivering clearer picture and sound. Digital signals can also provide more consistent reception within a broadcaster’s coverage area compared with traditional analog transmission.
But the disaster-warning capability may ultimately prove to be one of the most consequential advantages.
In 2024, Philippine Star reported that the NTC, DICT and disaster-management authorities were looking at integrating an emergency warning broadcast system into digital television, drawing comparisons with Japan’s disaster-alert infrastructure. At the time, officials also stressed the need to ensure that households still dependent on analog television could access digital services before analog broadcasting was discontinued.
The Philippines has also previously tested the use of digital television for disaster information. In 2018, the Philippine News Agency reported that PTV-Davao was preparing to pilot a broadcast information system using EWBS technology for disaster warnings.
The Bigger Question: Will Filipinos Actually Receive the Alerts?
The technology is only one piece of the puzzle.
For the system to be effective, three things have to work together: compatible receivers, functioning digital broadcast infrastructure, and timely emergency information from authorities.
That is why the country’s digital migration is important beyond the television industry.
A properly equipped digital TV could potentially serve as an additional emergency communication channel when people are at home watching television—even if the set is not actively being used.
For a country where disasters can develop rapidly, those extra minutes of warning can matter.
And as the Philippines moves deeper into its digital-TV transition, the television sitting in a Filipino household may soon have another job besides entertainment: helping warn families when danger is approaching.
