# DWCP-DTV

DWCP-DTV (channel 21) is a television station in Metro Manila, Philippines, serving as the flagship of the SolarFlix network. The station is owned by Southern Broadcasting Network through its licensee and subsidiary of Solar Entertainment Corporation. Its studios are located at the Third Floor Worldwide Corporate Center, Shaw Boulevard corner EDSA, Mandaluyong, while its hybrid digital transmitting facility is located at the Solar Entertainment Complex, along Nuestra Señora Dela Paz Subdivision, Barangay Sta. Cruz, Antipolo, Rizal.
DWCP-TV became the first local UHF TV station in Metro Manila that began broadcast in May 1992 as World TV 21. It operates daily from 8:00am to 12:00mn on terrestrial television, with programming available 24 hours daily across cable and satellite providers.

## History

Southern Broadcasting Network of Davao launched SBN Channel 21, the first local UHF TV station in Metro Manila since 1992. It was then known as World TV 21 by Kampana Television Corporation, which provided programming content from ABC, CNN and ESPN on this channel then. The idea is to bring back programming similar to the forcibly shut-down FEN Channel 17 of the former Clark US Air Base a year earlier due to the Eruption of Mt. Pinatubo.
Beginning on January 1, 2008, Solar Entertainment began to lease airtime on SBN, choosing to broadcast programming from its entertainment channel ETC. This partnership ended on March 2, 2011, as Solar transferred ETC to RPN. As a result, SBN renewed partnership with Solar Entertainment to create the news network Talk TV. On October 30, 2012, the channel was renamed as the Solar News Channel.
On December 1, 2013, SNC's programming was moved to RPN for wider national coverage, with ETC returned to SBN a day before.
In 2015, SBN ceased using its old analog transmitter tower at the Strata 2000 building in Pasig (which was obvious to consider even after Solar's purchase of SBN due to the old Sign-on and Sign-off sequences) and began using Solar's newly constructed tower located in Antipolo for a clearer and better signal reception in both the analog and digital signals.
As of September 12, 2019, SBN closed down its analog signal in favor of digital TV broadcast.

## Technical information

SBN launched its digital television broadcast in 2015, alongside another digital signal from Byers Communications. Solar Entertainment supplies its DTV channels through the new platform, allowing the company to launch the Easy TV DTT service. For unknown reasons, the transmitter's encryption system was activated throughout its run, making two of the station's subchannels receivable only on set-top boxes with this capability. The technical issue was fixed by September 25, 2017.
The station remained on the air, despite Easy TV's close of operations on September 30, 2019 but it ceases all of its freemium channels and remaining its free-to-air channels.

### Analog-to-digital transition

DWCP-TV terminated its analog signal on UHF channel 21, on September 12, 2019, as preparation for the Philippines' transition to digital terrestrial television. The station then flashcut its digital signal from its pre-transition channel 22 to the analog-era channel 21 for post-transition operations.
Starting May 25, 2020, the video output of DWCP-DTV, along with SBN's other digital stations, had been officially migrated to 16:9 widescreen format.
