This month I decided to take a break from talking about TV transmission to focus on TV reception.

You might not have noticed, but… some things ain’t worth protectin’.

We cannot deny how quickly lighting technology is advancing, nor how certain technologies are taking over and replacing those of the past.

In the past, I have written about out-of-band (OOB) interference between ATSC signals in different bands: the low VHF band into a high VHF channel and a high VHF band ATSC into a UHF channel.

In my August column, “The Audio World Without ISDN,” we looked at the impending demise of ISDN and the options available for those who can no longer get service.

One of my missions at this year’s NAB Show was to take a deeper assessment of the state of interoperability of audio-over-IP devices in preparation for an upcoming project.

Many stations will replace transmitters, RF systems, line and antennas as part of the channel repack after the incentive auction and it makes sense to select gear that will work for ATSC 3.0.

As previously covered in this column, IEEE 1588 Precision Time Protocol (PTP) is an essential part of a modern all-IP media production system.
