According to Nick who is a moderator on the Silicondust ATSC 3.0 forum, the firmware update will not require that their boxes be returned. Zapperbox will require their boxes to be returned to allow DRM.
The Antennaman is the person who claimed that both manufacturers would require their boxes to be returned but Silicondust claims that their box already has the correct hardware and only needs a firmware update. They are still in the process of working out the requirements. Here is a quote from their form:
We are working with A3SA on right now on DRM matters. We will not have a definitive answer until this work is complete.
The end-to-end solution must be certified, so the tuner, the storage device (if any), the playback solution, and the presentation device will all need to be certified.
