ATSC 3.0 / NextGen TV was switched on in Houston last week. If you have a recent model Samsung/LG/Sony TV and an antenna you can do a channel rescan to receive it. It gives higher quality sound, picture, 4k capability in the future.

KPRC channel now carries an interactive side menu where you can watch local news, weather, feature clips etc. at any time.

But there's a problem....if I play one of these side menu clips, it starts ok but after 5 seconds I get an error message saying "No signal. Antenna not connected or program unavailable" and the picture slowly fades to black. The sound continues until the end of the clip.

Is anyone else getting the same? I have a Sony Bravia 4K VH2
