ABS-CBN gave away a few set-top/converter set to some of its audience last year for ISDB-T. Umagang Kay Ganda and Ted Failon on DZMM-AM were the programs that gave these away. The set includes the set-top/converter set and an AV RCA cable to connect to their CRT or HDTV. The name given to it is TV+. TV+ does not have HDMI out. Therefore, users will see SD on whatever TV they connect it to.
ABS-CBN did not really explain what ISDB-T is all about in technical terms. ABS-CBN seems to be marketing the ISDB-T by introducing TV+ and explaining it as a new way to watch free TV very clearly without the interference of their old antenna.
I think that's a good way of putting it. Utilizing the advantage of clear pictures is its strength.
TV+ is not exclusively locked on to ABS-CBN and Studio 23. It can also tune in to GEM, PTV and TV5.
Meanwhile, GEM and PTV are datacasting too.
