A proprietary digital terrestrial set-top box (also known as the "Mahiwagang Black Box") which offers free-to-air legacy Philippine TV networks' channels and additional free-to-view channels from the ABS-CBN Corporation. The free-to-view channels include Cinemo!, Yey, DZMM Teleradyo, and the Knowledge Channel. The one-off cost for the box is ₱1,499 (approximately US$28) and viewers will need to insert the sim card provided with the box into their mobile phone to activate or decrypt the free-to-view channels. These channels are free-to-view in the sense that although they are not subject to a recurring subscription, they cannot be accessed on generic or non-proprietary ISDB-T receiving devices.
